2.1Nature of Business Acquired

On April 1, 2015 (the “Acquisition Date”), the Company and Rio Alto Mining Limited (“Rio Alto”) completed the previously announced acquisition by the Company of Rio Alto pursuant to a statutory plan of arrangement under section 193 of the Business Corporations Act (Alberta) (the “Arrangement”). The Arrangement was approved by shareholders of the Company and the shareholders of Rio Alto and received final court approval on March 30, 2015.

The Arrangement was completed pursuant to the terms of an arrangement agreement dated February 9, 2015 between the Company and Rio Alto (the “Arrangement Agreement”). Pursuant to the terms of the Arrangement Agreement, Rio Alto became a wholly-owned subsidiary of the Company.

Additionally, outstanding options of Rio Alto have been deemed to have been exchanged under the Arrangement, and the holders of Rio Alto options have received options to purchase Tahoe Shares. In accordance with the terms of the outstanding warrants to purchase Rio Alto Shares, each holder was entitled to receive upon exercise, 0.227 Tahoe Shares and C$0.001 in cash in lieu of one Rio Alto Share.

To give effect to the Arrangement, Tahoe (i) issued 75,991,381 Tahoe Shares to former holders of Rio Alto Shares, (ii) 2,011,244 Tahoe Shares to former holders of Rio Alto warrants upon exercise of such warrants (all of which have now been exercised), and (iii) authorized the issuance of up to an additional 3,374,449 Tahoe Shares issuable upon the exercise of the stock options held by former option holders of Rio Alto.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of Rio Alto Mining Limited:

We have audited the accompanying consolidated financial statements of Rio Alto Mining Limited, which comprise the consolidated statements of financial position as at December 31, 2014 and December 31, 2013, and the consolidated statements of net income and comprehensive income, consolidated statements of changes in equity and consolidated statements of cash flows for the years ended December 31, 2014 and December 31, 2013, and a summary of significant accounting policies and other explanatory information.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board, and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s Responsibility

Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.  We were not engaged to provide an audit of the Company’s internal control over financial reporting.  Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting.  Accordingly, we express no such opinion.

We believe that the audit evidence we have obtained in our audits is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of Rio Alto Mining Limited as at December 31, 2014 and December 31, 2013, and its financial performance and its cash flows for the years ended December 31, 2014 and December 31, 2013 in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board.

Notes to the Consolidated Financial Statements

For the years ended December 31, 2014 and 2013

(Expressed in thousands of United States dollars, except for per share and per ounce amounts)

1.NATURE OF OPERATIONS

Rio Alto Mining Limited (“Rio Alto” or the “Company”) is the parent company of a consolidated group. Rio Alto Mining Limited is incorporated under the laws of the Province of Alberta, with its registered office at Suite 1000 - 250 2nd Street S.W., Calgary, Alberta, T2P 0C1 and its head office at Suite 1950 - 400 Burrard Street, Vancouver, BC, V6C 3A6. The Company’s wholly-owned subsidiary La Arena S.A. (“La Arena”) owns the La Arena mineral project (“La Arena Project”) in Peru. The La Arena Project has two separate deposits, a gold oxide deposit (“Phase I”) and a copper/gold sulphide deposit (“Phase II”), and several exploration prospects. Phase I is in production and a feasibility study on the economic viability of developing Phase II is underway.

On August 5, 2014, Rio Alto acquired all of the outstanding shares of Sulliden Gold Corporation Ltd. (“Sulliden”) on the basis of 0.525 of a Rio Alto common share per each Sulliden common share (the “Exchange Ratio”), which combines their respective businesses (the “Transaction”). The key asset acquired in the Transaction is the Shahuindo Gold Project in Peru which is owned by the now 100% owned subsidiary Shahuindo S.A.C. and is in the development phase.

2.BASIS OF PREPARATION

The consolidated financial statements have been prepared in accordance with IFRS as issued by the International Accounting Standards Board (IASB). The summary of accounting policies is presented in Note 5.

The consolidated financial statements are presented in United States dollars (“USD”), which is the functional currency of the Company and its subsidiaries.

The Board of Directors approved these consolidated financial statements on March 13, 2015.

3.SIGNIFICANT JUDGEMENTS

When preparing the financial statements, management makes a number of judgements, estimates and assumptions about the recognition and measurement of assets, liabilities, income and expenses. Actual financial results may not equal estimated results due to differences between anticipated and actual events.

Significant management judgement

The following are significant management judgements in applying the accounting policies of the Company that have the most significant effect on the financial statements.

a.Functional currency

The functional currency for each of the Company’s subsidiaries, joint ventures and investments in associates, is the currency of the primary economic environment in which the entity operates. The Company has determined the functional currency of each material entity is the US dollar. Determination of functional currency requires judgement to determine the primary economic environment. The Company reconsiders the functional currency of its entities in light of new events or change in circumstances.

b.Own Use Contracts

A commodity contract within the scope of IAS 39 Financial Instruments: Recognition and Measurement (IAS 39) that is also a derivative is accounted for at fair value through profit and loss (FVTPL).

Contracts, such as the Gold Prepayment Agreement (“Prepayment”) (Note 17), that may be net cash settled under the contract; or when the non-financial item is readily convertible into cash are outside the scope of IAS 39 if they

RIO ALTO MINING LIMITED

Notes to the Consolidated Financial Statements

For the years ended December 31, 2014 and 2013

(Expressed in thousands of United States dollars, except for per share and per ounce amounts)

were entered into and continue to be held for the purpose of the receipt or delivery of the non-financial item in accordance with the entity’s expected purchase, sale or usage requirements and are not written option contracts. Contracts that are exempt from IAS 39 on these grounds are commonly referred to as “own use contracts” and are accounted for as executory contracts.

The Prepayment will be settled by delivering gold ounces in accordance with the Company’s normal sale and usage requirement; therefore, the Prepayment qualifies as an own use contract under which revenue is recognized as the notional ounces are delivered.

4.ESTIMATION UNCERTAINTY

Estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period are based on management’s experience and expectations of future events. Such estimates and assumptions are continually evaluated and management believes such estimates and assumptions are reasonable under the circumstances. Actual results could differ from estimated amounts by a material amount.

Matters that require management to make estimates and assumptions include, but are not limited to, the following:

a.Mineral reserves

The Company estimates its proven and probable mineral reserves on the basis of information compiled by appropriately qualified persons. The estimation of future cash flows expected to result from exploiting reserves includes assumptions about future foreign exchange rates, commodity prices, capital requirements, metal recovery and production costs. Changes in proven and probable mineral reserves estimates will impact the carrying value of mineral properties, plant and equipment, asset retirement obligations, recognition of deferred tax amounts and amortization expense.

b.Cost of sales and mineral inventory

In determining cost of sales management estimates the quantity of ore stacked on leach pads and metal content in process and the recoverable gold in this material to determine the average cost of goods sold during the period. Changes in these estimates can result in a change in costs of sales of future periods and the carrying amount of inventories.

Minerals inventory consists of mined ore, work-in-process and doré valued at the lower of average production cost or net realizable value. Doré represents a bar containing predominantly gold by value which must be refined offsite to return gold or silver in readily saleable form. Net realizable value is the estimated receipt from sale of inventory in the normal course of business, less anticipated costs to be incurred prior to sale. The production cost of mineral inventories is determined on a weighted average basis and includes cost of raw materials, direct labour, contract mining charges, overhead and amortization.

Costs are removed from mineral inventory as ounces of doré are produced at the average cost per recoverable ounce of gold. Estimates of recoverable gold are calculated from measured quantities of ore placed on the leach pad, the grade of ore placed on the leach pad (based on assay analysis), testing of leach solutions and a recovery percentage (based on testing of solution and ongoing monitoring of the rate of gold recovery).

c.Asset retirement obligation

Changes to the provision for reclamation and remediation are recorded with a corresponding change to the carrying value of the related asset. If this increase in the asset results in the asset exceeding its recoverable amount, the

RIO ALTO MINING LIMITED

Notes to the Consolidated Financial Statements

For the years ended December 31, 2014 and 2013

(Expressed in thousands of United States dollars, except for per share and per ounce amounts)

excess is charged to expense.

The provision for reclamation and remediation is assessed on an annual basis or when new information or circumstances merit a re-assessment. Estimates and assumptions are made in determining the provision for reclamation and remediation, including estimates of the extent and costs of the activities, technological changes, regulatory changes, foreign exchange rates, inflation rates and discount rates. The provision for asset retirement obligations represents management’s best estimate of the present value of the future reclamation and remediation obligation. Actual expenditures may differ from the recorded amount.

d.Income taxes

In assessing the probability of realizing income tax assets, management makes estimates related to expectations of future taxable income, the timing of reversals of temporary differences and the likelihood that tax positions taken will be accepted by tax authorities. Estimates of future taxable income are based on forecasted cash flows from operations and the application of existing tax laws. Where applicable, tax laws and regulations are unclear or subject to varying interpretations. It is possible that such changes to recorded tax amounts may be material. At the end of each reporting period, the Company reassesses unrecognized income tax assets.

e.Derivative liability

An option pricing model based on historic US dollar gold price volatility is used to estimate the fair value of the Company’s Gold Purchase Agreement described in Note 17. Differences in assumed volatility and actual volatility may significantly affect the fair value estimate. The company estimates the number of ounces that are available for purchase under the Gold Purchase Agreement. This estimate involves the exercise of significant judgment with respect to the interpretation of the Gold Purchase Agreement.

f.Impairment of long-lived assets

Whenever there is a change in circumstances such as, a substantive decrease in metal prices, an increase in operating costs, a decrease in mineable resources or a change in foreign taxes or exchange rates, reviews are undertaken to evaluate the carrying value of mineral properties and plant and equipment considering, among other factors: the carrying value of each type of asset; the economic feasibility of continued operations; the use, value or condition of assets when not in operation; and changes in circumstances that affect decisions to reinstall or dispose of assets. For assets in the development stage reviews are undertaken to evaluate the carrying value of mineral properties on an annual basis or when circumstances require.

Future cash flows used to assess whether carrying values are recoverable are estimated based on expected future production, commodity prices, foreign exchange rates, discount rates, operating costs, reclamation costs and capital costs. Management’s estimate of future cash flows is subject to risks and uncertainties, and it is possible that changes in circumstances or unanticipated events may occur that affect management’s estimate of the recoverability of assets. To the extent that the carrying amount of assets exceeds the recoverable amount, the excess is charged to expense.

Impairment of an asset exists if the expected recoverable amount from the use or disposal of the asset is less than its carrying amount. The determination of recoverable amount is based on fair value estimations.

Fair value is determined with reference to estimates of future discounted cash flow or to recent transactions involving dispositions of similar assets. Management believes that the estimates applied in impairment assessment are reasonable; however, such estimates are subject to significant uncertainties. Although management has made its best estimate of these factors based on current and expected conditions, it is possible that the underlying assumptions could change and impairment charges may be required. Such charges could be material.

(vii)Company constructing an electrical sub-station for the Shahuindo Project

All inter-company transactions and balances are eliminated on consolidation.

b.Functional and presentation currency

The consolidated financial statements are presented in US Dollars, which is also the functional currency of the Company.

The functional currency for each of the Company’s subsidiaries is the currency of the primary economic environment in which the entity operates. The Company has determined the functional currency of each material entity is the US dollar. Determination of functional currency requires judgment to determine the primary economic environment. The Company reconsiders the functional currency of its entities in light of new events or change in circumstances.

c.Foreign currency transactions and balances

Transactions in foreign currencies are translated into the functional currency using exchange rates prevailing at the date of the transactions. Monetary assets and liabilities denominated in foreign currencies at a reporting date are translated into the functional currency at the exchange rate at that date. An exchange gain or loss arising on translation or settlement of a foreign currency-denominated monetary item is included in profit or loss.

Non-monetary items are not translated at year-end exchange rates. They are measured at historical cost (using the exchange rates at the transaction date), except for non-monetary items measured at fair value which are translated using the exchange rates at the date when fair value is determined.

d.     Revenue recognition

Revenue is derived from the sale of gold and silver and it is measured at the fair value of consideration received or receivable. Revenue is recognized when all of the following criteria are met:

·The significant risks and rewards of ownership have been transferred;

·Neither continuing managerial involvement to the degree usually associated with ownership nor effective control over the goods sold has been retained;

·The amount of revenue can be measured reliably;

·It is probable that the economic benefits associated with the transaction will flow to the Company; and

·The costs incurred or to be incurred in respect of the transaction can be measured reliably.

Revenue related to ounces of gold delivered under both the Gold Prepayment Agreement and Purchase Agreement (Note 17) is measured based on the contractual terms of those agreements and it is recognized upon shipment of ounces.

Proceeds from the sale of metals produced prior to commercial production are capitalized as part of costs deferred during development.

e.Earnings per share

Basic earnings per common share is calculated by dividing the earnings for the period by the weighted average number of common shares outstanding during the reporting period. Diluted earnings per share is calculated by adjusting the weighted average number of shares outstanding for the dilutive effect of options and warrants. The computation of diluted earnings per share assumes the conversion, exercise or contingent issuance of securities when such conversion would have a dilutive effect on earnings. It is assumed that outstanding options, warrants and similar items are exercised or converted into shares and that the proceeds that would be realized upon such exercise or conversion are used to purchase common shares at the average market price per share during the relevant reporting period with such hypothetically purchased shares causing a corresponding reduction in the number of shares used in the computation of diluted earnings per share.

f.Cash and cash equivalents

Cash and cash equivalents include cash on hand and short-term money market instruments that are readily convertible to known amounts of cash within 90 days.

g.Consumable inventory

Consumable inventory includes consumable supplies and spare parts to be used in production. It is valued at the lower of weighted average cost or net realizable value. Replacement cost of supplies is generally used as the best estimate of net realizable value.

Any write-down of inventory is recognized as an expense in the period the write-down occurs.

h.Plant and equipment

Plant and equipment are recorded at cost less accumulated amortization and impairment losses, if any. Plant and equipment are amortized over the lesser of their estimated useful lives or the life of the related ore body. Repair and maintenance costs that do not enhance the service potential of an asset are expensed as incurred. Costs incurred to enhance the service potential of an asset are capitalized and amortized over the remaining useful life of the improved asset. When assets are retired or sold, the resulting gain or loss is reflected in earnings.

Notes to the Consolidated Financial Statements

For the years ended December 31, 2014 and 2013

(Expressed in thousands of United States dollars, except for per share and per ounce amounts)

Amortization is recorded on the following basis:

Heap leach pad and ponds	Units of production (“UOP”)
Mobile and field equipment	25% per annum
Plant and equipment	Units of production
Other mine assets	10% - 20% per annum
Other assets	10% - 25% per annum
Leasehold improvements (other assets)	Term of the lease

Assets that will only be utilized at a certain phase of the mine (heap leach pad and ponds, plant and equipment specific to certain phases of a mine) are amortized over UOP based on proven and probable reserves. Assets that can be used at more than one phase of the mine are amortized over their useful lives.

Amortization incurred prior to commercial production is capitalized as part of mineral properties and development costs.

i.Exploration and evaluation expenditures

Acquisition costs for exploration and evaluation stage properties are deferred if a future economic benefit is more likely than not to be realized.

Upon demonstrating technical feasibility and commercial viability, capitalized exploration and evaluation costs are transferred to development costs within mineral properties. Technical feasibility and commercial viability generally coincides with the establishment of mineral reserves but this determination may be affected by management’s assessment of other factors including legal, environmental, social and governmental factors.

Prospecting and initial exploration costs to define and delineate a mineral deposit that has no demonstrable reserves are expensed.

The carrying values of capitalized amounts are reviewed annually, or when there are indications of potential impairment.

j.Mineral properties and development costs

Mineral properties are carried at cost less accumulated depletion and include:

(i)Costs of acquiring production, development and exploration stage properties in asset acquisition transactions, including earn-in agreements;

(ii)Expenditures incurred to develop mining properties;

(iii)Economically recoverable exploration and evaluation expenditures;

(iv)Borrowing costs incurred that are attributable to qualifying mining properties;

(v)Certain costs incurred during production, net of proceeds from sales, prior to reaching commercial production; and

(vi)Estimates of reclamation and closure costs.

The recorded amount of capitalized costs may not reflect recoverable value, which is dependent on development programs, the nature of the mineral deposit, commodity prices, development and operating costs and the Company’s ability to bring projects into production.

Once a property reaches commercial production capital costs are amortized on units of production over the expected life of the property’s proven and probable reserves and costs of any additional work on that property are expensed as incurred, except for development programs that extend the life or enhance the value of a property, which are capitalized and depleted over the remaining life of the ore body.

(Expressed in thousands of United States dollars, except for per share and per ounce amounts)

A mineral property is derecognized upon disposal or considered to be impaired when no or limited future economic benefits are expected to arise from continued use of the asset. Any gain or loss on derecognition or impairment of an asset, determined as the difference between the proceeds received or expected to be received and the carrying amount of the asset, are recognized in the determination of profit or loss.

k.Asset retirement obligation

Asset retirement obligations encompass legal, statutory, contractual or constructive obligations associated with the retirement of a long-lived tangible asset that result from the acquisition, construction, development or normal operation of a long-lived asset. The retirement of a long-lived asset results from an other-than-temporary removal from service, including sale of the asset, abandonment or disposal in some other manner such as depletion of reserves.

The Company recognizes the fair value of an estimated liability for the future cost of restoring exploration, development and mine sites with a corresponding increase to the carrying value of the related mineral property interest. The Company amortizes the amount added to mineral property interests using the amortization method established for the related asset. Changes in asset retirement obligations due to the passage of time are measured by an interest method of allocation whereby the change is recognized as an increase in the associated liability and by an accretion expense in profit or loss. Changes resulting from revisions to the timing of restoration spending or the amount of the original estimate of undiscounted asset retirement obligation cash flows are recognized as an increase or decrease in the carrying amount of the asset retirement obligation resulting in a corresponding increase or decrease in the carrying value of the related asset.

l.Stripping costs

The Company accounts for stripping costs in accordance with IFRIC 20 — Stripping Costs in the Production Phase of Surface Mine (“IFRIC 20”), which applies to the costs incurred to remove mine waste materials to gain access to mineral ore deposits during production. Stripping costs incurred during the development of a mine are capitalized within mineral properties. Stripping costs incurred subsequent to commencement of commercial production are variable production costs that are included in the cost of inventory produced during the period in which they are incurred, unless the stripping activity can be shown to give rise to future benefits from the mineral property, in which case the stripping cost would be deferred. Future benefits arise when stripping activity increases the future output of the mine by providing access to an extension of an ore body or to a new ore body. Capitalized stripping costs are depleted based on the UOP method using proven and probable mineral reserves as the depletion base. The Company has no capitalized stripping costs.

m.Impairment of non-financial assets

For the purposes of assessing impairment, the recoverable amount of an asset is estimated. If it is not possible to estimate the recoverable amount of an individual asset, the asset is included in the cash-generating unit to which it belongs and the recoverable amount of the cash generating unit is estimated. As a result, some assets are tested individually for impairment and some are tested at the cash-generating unit level. A cash-generating unit is the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or group of assets.

An impairment loss is recognized for the amount by which the asset’s or cash-generating unit’s carrying amount exceeds its recoverable amount. Recoverable amounts are either value-in-use or fair value less cost of disposal. To determine an asset’s value-in-use, management estimates expected future cash flows from each asset or cash-generating unit and determines a suitable interest rate in order to calculate the present value of those cash flows. Future cash flows used in the determination of value in use are estimated based on expected future production commodity prices, operating costs, reclamation costs and capital costs. Fair value less cost of disposal is determined with reference to estimates of discounted future cash flows or to recent transactions involving dispositions of similar assets.

RIO ALTO MINING LIMITED

Notes to the Consolidated Financial Statements

For the years ended December 31, 2014 and 2013

(Expressed in thousands of United States dollars, except for per share and per ounce amounts)

An impairment loss for a cash-generating unit is allocated on a pro rata basis to the assets in the cash-generating unit. All assets are subsequently reassessed for indications that an impairment loss previously recognized may no longer exist or may have decreased. An impairment charge is reversed if the cash-generating unit’s recoverable amount exceeds its carrying amount. Where an impairment loss subsequently reverses, the carrying amount of the impaired asset or cash generating unit is increased to the revised estimate of its recoverable amount to the extent that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset or cash generating unit in prior periods.

n.Provisions

Provisions are recognized when the Company has an obligation, either legal or constructive, as a result of a past event and it is probable that a future outflow of resources will be required to settle the obligation. Provided that a reliable estimate can be made of the amount of the obligation, a provision for a liability of uncertain timing is recorded.

Provisions are measured at the present value of the outflow of resources expected to be required to settle the obligation using a pre-tax rate that reflects the time value of money and the risk specific to the obligation. Any increase in a provision due to the passage of time is recognized as a financing expense. Any increase in a provision due to a change in estimate is expensed.

o.Income taxes

Tax expense recognized in profit or loss comprises the sum of current and deferred taxes, except where they relate to items that are recognized in other comprehensive income or directly within equity, in which case the related current and deferred tax is recognized in other comprehensive income or equity.

Current tax is based on tax rates and tax laws that have been enacted or substantively enacted by the end of the reporting period and is payable on taxable profit which differs from profit or loss in the financial statements. Current income tax liabilities or assets are obligations to, or claims from, fiscal authorities relating to the current or prior reporting periods that are unsettled at the reporting date.

Deferred taxes are calculated by applying the liability method to temporary differences between the carrying amounts of assets and liabilities and their tax bases. Deferred tax assets and liabilities are calculated at tax rates expected to apply during the anticipated periods of realization, provided that such rates are enacted or substantively enacted by the end of the reporting period. Deferred tax assets are recognized to the extent that it is probable that they will be able to be utilized to reduce future taxable income. Deferred tax is not provided on the initial recognition of an asset or liability unless the related transaction is a business combination or affects tax or accounting profit. Deferred tax on temporary differences associated with shares in subsidiaries and joint ventures is not provided if reversal of these temporary differences can be controlled by the Company and it is probable that reversal will not occur in the foreseeable future. Deferred tax assets and liabilities are offset when the Company has a right and intention to offset current tax assets and liabilities from the same taxation authority.

Royalties and revenue-based taxes are accounted for as an income tax when they have the characteristics of an income tax. This is considered to be the case when such taxes are imposed under government authority and the amount payable is based on income - rather than being determined on the basis of production or as a percentage of revenue — after adjustment for temporary differences. For such arrangements, current and deferred tax is provided for on the same basis as described for other forms of taxation. Obligations arising from royalty arrangements that do not satisfy these criteria are recognized as current changes and included in cost of sales.

p.Share-based payments

The Company accounts for share-based payments using a fair value based method (Black-Scholes Option Pricing Model) with respect to all share-based payments. For directors and employees, the fair value of options is measured at the date of grant. Share-based payments to non-employees, whereby the Company receives goods or services

RIO ALTO MINING LIMITED

Notes to the Consolidated Financial Statements

For the years ended December 31, 2014 and 2013

(Expressed in thousands of United States dollars, except for per share and per ounce amounts)

as consideration for its equity instruments are, when determinable, recorded at the fair value of the goods or services received. If the fair value of the goods and services received are not determinable, then the fair value of the share based payment is used and is measured on the date services are received.

The fair value of options granted as share-based payments is charged to profit or loss over the vesting period with a corresponding credit to share option reserve within shareholders’ equity. For directors and employees the charge is recognized over the option vesting period based on the best available estimate of the number of share options expected to vest. Estimates are subsequently revised if there is any indication that the number of share options expected to vest differs from the previous estimate. No adjustment is made to expenses recognized in prior periods when options vested. For non-employees the charge is recognized over the related service period. When stock options are exercised the corresponding amount credited to the share option reserve is transferred to share capital.

In the event stock options are forfeited the fair value of any vested and expired stock options remains in the share option reserve.

q.Derivative instruments

Derivative instruments, including derivative instruments embedded in other contracts and instruments designated for hedging activities, are recognized as either assets or liabilities in the balance sheet and measured at fair value. The Company has not used derivative instruments to hedge exposures to cash flow or foreign currency risks. Any change in the fair value of a derivative or an embedded derivative not designated as a hedging instrument is recognized as a gain or loss in the profit or loss.

r.Non-derivative financial instruments

The Company classifies financial assets as fair value through profit or loss, available-for-sale financial assets, held-to-maturity investments or as loans and receivable. The Company classifies financial liabilities as either at fair value through profit or loss or at amortized cost using the effective interest method. Financial assets and financial liabilities are recognized initially at fair value. Transaction costs, other than those related to financial instruments classified as financial assets and liabilities at fair value through profit or loss, are added to the fair value of the financial asset and financial liability on initial recognition and amortized using the effective interest method.

Financial assets and financial liabilities classified as fair value through profit or loss are re-measured at fair value at the end of each reporting period, with gains or losses recognized in profit and loss.

Financial assets classified as available for sale are re-measured at fair value at the end of each reporting period with gains or losses recognized in other comprehensive income until assets are derecognized or become impaired.

Financial assets classified as loans and receivables and held-to-maturity investments and financial liabilities that are not classified as fair value through profit or loss are subsequently measured at amortized cost using the effective interest method.

The Company assesses, at the end of each reporting period, whether there is objective evidence that financial assets are impaired. A financial asset is impaired and impairment losses are incurred if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the asset that has a negative impact on the estimated future cash flows of the financial asset that can be reasonably estimated.

6.CHANGES IN ACCOUNTING POLICIES

a.New pronouncements effective January 1, 2014

The Company has adopted the following new and revised standards effective January 1, 2014. These changes were made in accordance with the applicable transitional provisions.

IFRIC 21 — Levies

In May 2013, the IASB issued IFRIC 21 — Levies (“IFRIC 21”), an interpretation of IAS 37 — Provisions, Contingent Liabilities and Contingent Assets (“IAS 37”), on the accounting for levies imposed by governments. IAS 37 sets out criteria for the recognition of a liability, one of which is the requirement for the entity to have a present obligation as a result of a past event (“obligating event”).

IFRIC 21 clarifies that the obligating event that gives rise to the liability is the activity that triggers the payment of the levy, as identified by the government’s legislation. If this activity arises on a specific date within an accounting period then the entire obligation is recognized on that date.

The Company applied IFRIC 21 retrospectively in accordance with its transitional provisions, and it had no material effect on the consolidated financial statements for any period presented.

Offsetting Financial Assets and Financial Liabilities (Amendments to IAS 32)

These amendments clarify the application of certain offsetting criteria in IAS 32, including:

·the meaning of ‘currently has a legally enforceable right of set-off’

·that some gross settlement mechanisms may be considered equivalent to net settlement.

The amendments have been applied retrospectively in accordance with their transitional provisions. As the Company does not currently present any of its financial assets and financial liabilities on a net basis using the provisions of IAS 32, these amendments had no material effect on the consolidated financial statements for any period presented.

Recoverable Amount Disclosures for Non-Financial Assets (Amendments to IAS 36)

These amendments clarify that an entity is required to disclose the recoverable amount of an asset (or cash generating unit) whenever an impairment loss has been recognized or reversed in the period. In addition, they introduce several new disclosures required to be made when the recoverable amount of impaired assets is based on fair value less costs of disposal, including:

·additional information about fair value measurement including the applicable level of the fair value hierarchy, and a description of any valuation techniques used and key assumptions made

·the discount rates used if fair value less costs of disposal is measured using a present value technique.

The amendments have been applied retrospectively in accordance with their transitional provisions, and had no material effect on the consolidated financial statements for any period presented.

b.Changes to standards that are not yet effective and have not been early adopted

The following accounting standards that are not yet effective have not been adopted early by the Company.

IFRS 9 — Financial Instruments (2014)

The IASB recently released IFRS 9 “Financial Instruments” (2014), representing the completion of its project to replace IAS 39 “Financial Instruments: Recognition and Measurement”. The new standard introduces extensive

RIO ALTO MINING LIMITED

Notes to the Consolidated Financial Statements

For the years ended December 31, 2014 and 2013

(Expressed in thousands of United States dollars, except for per share and per ounce amounts)

changes to IAS 39’s guidance on the classification and measurement of financial assets and introduces a new expected credit loss model for the impairment of financial assets. IFRS 9 also provides new guidance on the application of hedge accounting.

The new standard is required to be applied for annual reporting periods beginning on or after January 1, 2018.

The Company is evaluating the impact that IFRS 9 (2014) is expected to have on its consolidated financial statements.

IFRS 15 — Revenue from Contracts with Customers

IFRS 15 presents new requirements for the recognition of revenue, replacing IAS 18 “Revenue”, IAS 11 “Construction Contracts”, and several revenue-related Interpretations. The new standard establishes a control-based revenue recognition model and provides additional guidance in many areas not covered in detail under existing IFRSs, including how to account for arrangements with multiple performance obligations, variable pricing, customer refund rights, supplier repurchase options, and other common complexities.

IFRS 15 will be effective for reporting periods beginning on or after January 1, 2017.

The Company is evaluating the impact that IFRS 15 is expected to have on its consolidated financial statements.

Amendments to IFRS 11 — Joint Arrangements

These amendments provide guidance on the accounting for acquisitions of interests in joint operations constituting a business. The amendments require all such transactions to be accounted for using the principles on business combinations accounting in IFRS 3 “Business Combinations” and other IFRSs except where those principles conflict with IFRS 11. Acquisitions of interests in joint ventures are not impacted by this new guidance.

The amendments are effective for reporting periods beginning on or after January 1, 2016.

The Company is evaluating the impact that the Amendments to IFRS 11 is expected to have on its consolidated financial statements.

7.SHAHUINDO ACQUISITION

On August 5, 2014, Rio Alto acquired all of the outstanding shares of Sulliden Gold Corporation Ltd. (“Sulliden”) in exchange for 0.525 shares (“exchange ratio”) of Rio Alto common stock for each outstanding common share of Sulliden, excluding the 26,966,292 common shares of Sulliden already held by Rio Alto as described in Note 10. The Transaction was accounted for as an acquisition of assets. The primary asset of Sulliden was the Shahuindo Gold Project in Peru.

In addition to the 151,694,886 shares of Rio Alto issued in exchange for the outstanding shares of Sulliden, 750,000 Deferred Share Units (“DSUs”) and 2,510,000 Restricted Share Units (“RSUs”) were settled by the issuance of 393,750 and 1,317,754 shares of Rio Alto, respectively. The acquisition purchase price reflects the opening market price of Rio Alto’s common shares on August 5, 2014, which was CAD $2.54/share.

Each Sulliden warrant or stock option which gave the holder the right to acquire shares in the common stock of Sulliden was exchanged for a warrant or stock option which gave the holder the right to acquire shares in the common stock of Rio Alto on the same basis as the exchange ratio of Sulliden common shares for Rio Alto common shares. These options and warrants have been included in the purchase price at their fair value based on the Black-Scholes pricing model using the following weighted average assumptions:

	Options			Warrants
Issued	10,995,756			9,910,112
Strike price	$	2.42		$	2.39
Risk-free interest rate	1.09		%	1.06		%
Expected option life (years)	2.0			0.7
Expected price volatility	56		%	58		%

On completion of the Transaction, Sulliden shareholders received 0.10 of a common share in a newly incorporated company called Sulliden Mining Capital Inc. (“Sulliden Mining”) for each Sulliden common share held. Sulliden Mining was capitalized with CAD $25 million in cash from Rio Alto.

The purchase price has been allocated to the assets acquired and liabilities assumed based on their relative fair values on the closing date. The purchase price allocation is a result of management’s best estimates and assumptions after taking into account all relevant information available. The purchase price has been determined and allocated as follows:

Purchase price including shares owned previously:
Fair value of shares issued	$	352,650
Fair value of Sulliden shares owned previously	32,788
Fair value of shares issued to settle DSU and RSU	3,979
Fair value of stock options issued	9,083
Fair value of share purchase warrants issued	5,030
Cash	22,895
Transaction costs	6,414
Total purchase price	$	432,839
Purchase price allocation:
Cash and cash equivalents	$	8,776
Accounts receivable and prepaid expenses	2,950
IGV receivable	12,204
Plant and equipment	22,752
Mineral properties and deferred exploration costs	388,018
Accounts payable and accrued liabilities	(1,861		)
Net assets acquired	$	432,839

b.Sulliden Mining

On completion of the Transaction, Sulliden shareholders received 0.10 of a common share in a newly incorporated company called Sulliden Mining Capital Inc. (“Sulliden Mining”) for each Sulliden common share held. As a result, Rio Alto received 2,696,629 shares of Sulliden Mining. On the date of the Transaction, the fair value of the Sulliden shares, net of the fair value of the Sulliden Mining shares received, formed part of the purchase price of the assets acquired in the Transaction (Note 7). Sulliden Mining was capitalized with CAD $25 million in cash from Rio Alto. Sulliden Mining holds a 100% interest in the East Sullivan Property in Val-d’Or, Quebec.

c.Santa Barbara

In February 2013, the Company purchased 2,500,000 common shares of Santa Barbara at a price of CAD $0.08 per share, for total consideration of CAD $200.

d.Duran

The Company holds 5,000,000 units of Duran. The units consist of one common share of Duran and one half of a Series A Warrant and one half of a Series B Warrant (the “Duran Units”).

A whole Series A Warrant may be converted into one common share upon payment of CAD $0.25 at any time until the date that is the earlier of (i) December 31, 2014, and (ii) the date that is thirty days after the date notice is given to Rio Alto that the common shares have closed at or above CAD$0.25 for a period of twenty consecutive trading days on the TSX Venture Exchange (the “TSXV”) so long as such period occurs after September 28, 2013. The 2,500,000 Series A Duran Ventures Warrants held by the Company expired unexercised on December 31, 2014.

A whole Series B Warrant may be converted into one common share upon payment of CAD $0.35 at any time until the date that is the earlier of (i) March 28, 2015 and (ii) the date that is thirty days after notice is given to Rio Alto that the common shares have closed at or above CAD$0.35 for a period of twenty consecutive trading days on the TSXV so long as such period occurs after September 28, 2014.

Subject to the performance of certain conditions, Rio Alto may earn up to a 70% interest in Duran’s Minasnioc Gold-Silver Property (“Minasnioc”) and a 65% interest in Duran’s Ichuña Copper-Silver Property (“Ichuña”). In order to complete its earn-in option for the Minasnioc and Ichuña properties, Rio Alto must convert 100% of the warrants included in the Duran Units.

In June 2013, Rio Alto decided to terminate the Ichuña option. In November 2014, Rio Alto decided to terminate the Minasnioc option.

Other mine assets include the La Arena and Shahuindo camp offices and accommodation, with a carrying value of $21,182 at December 31, 2014 ($17,481 — December 31, 2013), and also the La Ramada power substation, property of Empresa de Energia Yamobamba SAC, which was commissioned in November 2014 and has a carrying value of $20,969 at December 31, 2014.

Land and lease permits consist of $18,116 for La Arena ($12,502 — December 31, 2013) and $11,755 for the Shahuindo Gold Project ($11,020 acquired in the Transaction).

Other assets consist of office equipment and leasehold improvements.

In the third quarter of 2013, the Company determined the carrying value of surface rights relating to an exploration project carried at $7,261 was impaired. The Company determined that the property was not viable as the gold mineralization at the property did not justify the cost of development.

16.INCOME TAXES

Income taxes differ from the amount that would be determined in applying the combined federal and provincial statutory income tax rate of 26% in the year ended December 31, 2014 (December 31, 2013 — 25.75%) to income before income taxes. The difference results from the following:

	December 31, 2014		December 31, 2013
Income before taxes	$	102,162	$	78,666
Income tax provision using the statutory tax rates	26,562		20,464
Difference in foreign tax rates	10,034		7,236

17.DEFERRED REVENUE AND DERIVATIVE LIABILITY

In 2011, the Company received $50,000 under a Gold Prepayment Agreement (“Prepayment”) and simultaneously entered into an off take agreement — the Gold Purchase Agreement (“Purchase Agreement”). The proceeds of the Prepayment were to partially fund development of Phase I. The Purchase Agreement includes a derivative liability (written option). An option pricing model that considers gold volatility is used to estimate the fair value of the derivative liability. Drawdowns of the Prepayment were initially apportioned to derivative liability based on estimated fair value with the residual amount allocated to deferred revenue.

a.Deferred revenue consists of:

	December 31, 2014			December 31, 2013
Opening balance	$	8,040		$	14,932
Cash settlement of deferred revenue	—			(4,630		)
Deliveries to recognize deferred revenue	(8,040		)	(2,262		)
Ending balance	$	—		$	8,040

Notes to the Consolidated Financial Statements

For the years ended December 31, 2014 and 2013

(Expressed in thousands of United States dollars, except for per share and per ounce amounts)

Under the Prepayment, the Company was committed to deliver a notional amount of 1,941 ounces of gold each month until October 2014. Once the accumulated monthly deliveries total 61,312 notional ounces of gold, the Prepayment is settled. The actual monthly delivery of gold ounces may vary by 5 per cent from 1,941 ounces for every $100 dollar change in the gold price from a base price of $1,150 per ounce, subject to limits at $1,450 and $950 per ounce. At a price of $1,450 or more the monthly delivery would be 85 per cent of 1,941 ounces and 115 per cent of 1,941 ounces if the price of gold was $950 or less.

The Company had the option to prepay gold ounces remaining to be delivered under the Prepayment, in whole or in part, at any time without penalty in either ounces of gold or the equivalent in cash at the then prevailing gold price. In April 2013, the Company made a one-time cash payment of $10,057 to settle 7,882 notional ounces to be delivered under the Prepayment. The price per ounce embedded in the Prepayment was lower than the price of gold when the cash payment was made. As a result, only the price per ounce embedded in the Prepayment was recognized as a deferred revenue fulfillment. The cash payment of $10,057 reduced the deferred revenue balance by $4,630 while the $5,427 balance was recorded as a loss on the settlement of the Prepayment.

The remaining committed ounces were settled in July 2014.

b.Derivative liability consists of:

	December 31, 2014			December 31, 2013
Opening balance	$	734		$	2,044
Change in fair market value of derivative liability	(734		)	(1,310		)
Ending balance	$	—		$	734

Under the Purchase Agreement the Company granted an option that allows the holder to purchase gold produced from two oxide pits (the Calaorco pit and the Ethel pit) up to an estimated amount of 634,000 ounces. The option holder may elect to pay one of either the London Gold Market AM Fixing Price or the Comex (1st Position) Settlement Price over predetermined periods of time. The option holder’s election represents an embedded derivative and is accounted for as a written call option. Changes in the fair value of the liability are reflected in profit or loss.

In the fourth quarter of 2014, the Company delivered the final estimated remaining ounces owing under the obligation. Subsequent to delivering the final estimated remaining ounces owing under the obligation, the Company was informed by the option holder that the option holder was in disagreement with the Company’s conclusion that the total obligation had been fulfilled. As more particularly described in the 2015 Technical Report, the gold mineral resources and mineral reserves of the body of gold oxide mineralization within the Calaorco pit described in the 2010 Report have increased, while the Ethel pit has been exhausted through mining.  As a result of the increased gold mineral resources and mineral reserves, the contracting parties are working together to reach an agreed upon interpretation of the Gold Purchase Agreement. Management cannot, at this time, reasonably estimate the number of ounces, if any, that the Company will be obligated to deliver to the counterparty over and above the 634,000 ounces already delivered through October 2014. In the interim, Rio Alto has voluntarily re-commenced delivery of gold produced from the Calaorco pit to the counterparty with a view to reaching an agreement regarding the interpretation of the Gold Purchase Agreement.

18.WARRANT LIABILITY

The warrant liability consists of the following:

	Warrants	Exercise Price (CAD$/warrant)		Warrant liability
Balance assumed on completion of the Transaction, August 5, 2014 (Note 7)	9,910,112	$	2.39	$	5,030
Change in fair value during the period	—	—		757
Balance, December 31, 2014	9,910,112	$	2.39	$	5,787

On August 5, 2014, the Company issued 9,910,112 replacement warrants on completion of the Transaction. The Black-Scholes Option Pricing Model is used to estimate the fair value of options granted and changes in the fair value of the liability are reflected in profit or loss. The warrants expire on April 12, 2015.

19.DEBT

The Company borrowed $3,000 in September 2011 bearing annual interest at 3-month LIBOR plus 6%. The debt matured in October 2014. As security for the Prepayment and the $3,000 loan, the Company granted a charge over its shares of La Arena and substantially all of the Company’s assets. The $3,000 loan and accrued interest of $584 were repaid in full in July 2014.

In July 2014, the Company received funds of $35,000 from BCP Banco de Credito del Peru (“BCP”) as part of a $50,000 credit facility agreement signed on June 16, 2014. The loan has a one-year term and bears annual interest at 30-day LIBOR plus 2.60%. The funds will be used for working capital. As security for this loan, the Company granted a charge over the shares of its subsidiary Empresa de Energia Yamobamba SAC and the rights of collection and future flows derived from the sale of concentrates of minerals or other products.

20.ASSET RETIREMENT OBLIGATION

	December 31, 2014			December 31, 2013
Opening balance	$	22,728		$	16,921
Accretion expense	1,591			1,547
Reclamation spending	(180		)	(918		)
Adjustment due to timing of expenditures and change in discount rate	—			5,178
Ending balance	$	24,139		$	22,728

The Company’s original reclamation and closure plan for the La Arena Gold Mine was filed with the Ministry of Energy and Mines in Peru in October 2012. The estimated undiscounted closure obligation at that time was $38,100, which when discounted at a rate of 10.25% resulted in an asset retirement obligation of $16,921 as at December 31, 2012.

A rate of 7.0% was used to discount estimated future costs at December 31, 2013. The decrease in the rate was due to a reassessment of the liability specific risk. This, combined with an adjustment of the expected timing of certain future expenditures due to a revised mine closure plan, resulted in a net increase to the asset retirement obligation of $5,178 with a corresponding increase to “Phase I” Mineral Properties (Note 14). The asset retirement obligation is continuously reviewed and therefore figures are subject to change.

The carrying value of the obligation is increased by periodic accretion charges reflected within profit and loss. The

Company posted a letter of credit, which at December 31, 2014 is in the amount of $5,014 as a partial guarantee of its closure obligations. Reclamation and closure activities include land and water rehabilitation, demolition of buildings and mine facilities, on-going care and maintenance and other costs. Cumulative to December 31, 2014, $1,522 has been spent on reclamation activities.

21.EQUITY

a.Share capital

Authorized share capital consists of an unlimited number of common shares of which 332,605,064 were issued and outstanding as at December 31, 2014 (December 31, 2013 — 176,767,682). The Company also has authorized an unlimited number of preferred shares of which none have been issued.

Upon completion of the Transaction described in Note 7, the Company issued 153,406,390 common shares. The Company also issued 2,430,992 common shares during the year ended December 31, 2014 upon the exercise of options as set out in note (b) below.

b.Share-based payments

The Company’s stock option plan authorizes the directors to grant options to executive officers, directors, employees and consultants enabling them to acquire from treasury up to that number of shares equal to 10 per cent of the issued and outstanding common shares of the Company.

The exercise price of options granted is determined by the directors, subject to regulatory approval, if required. Options may be granted for a maximum term of 10 years and vest as determined by the board of directors. The Black-Scholes Option Pricing Model is used to estimate the fair value of options granted. Vesting periods range from immediate vesting to vesting over a 3-year period.

28.CAPITAL MANAGEMENT

The capital of the Company consists of items included in equity and debt, less cash and cash equivalents.

	December 31, 2014			December 31, 2013
Equity	$	680,866		$	261,641
Debt	35,000			3,446
	715,866			265,087
Less Cash and cash equivalents	(48,165		)	(27,077		)
Capital	$	667,701		$	238,010

The Company has no externally imposed capital requirements. The objectives of the Company’s capital risk management program are to safeguard the Company’s ability to continue as a going concern, provide returns to shareholders, protect shareholder value, provide benefits for other stakeholders, and ensure the growth of the business. The Company considers the items in equity and debt as capital and manages its capital structure by issuing treasury shares, engaging in commodity-backed transactions, the potential sales of assets, the incurrence of debt or the return of capital to shareholders in light of economic conditions and the characteristics of the Company’s assets.

The Company’s capital structure reflects the Company’s focus on growth in a capital intensive industry with lengthy development times as well as the risks associated with exploration and development activities due to factors that are beyond the Company’s control including, without limitation, the receipt of necessary permits, the availability of financial and human resources and the volatility of commodity prices. The adequacy of the Company’s capital structure is assessed on an on-going basis and is adjusted as necessary and as financial markets permit in order to fund exploration and development programs. Exploration and development activities may be delayed or accelerated as circumstances or events change.

29.FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

The Company’s financial instruments consist of cash and cash equivalents, restricted cash, accounts receivable, other financial assets, accounts payable and accrued liabilities, debt, derivative liability, and warrant liability.

·Cash and cash equivalents, restricted cash, and accounts receivable are classified as loans and receivables and are measured at amortized cost.

·Accounts payable and accrued liabilities, and debt are classified as other financial liabilities.

·Other financial assets are classified as fair value through profit or loss, except for the Sulliden Mining shares which are classified as available-for-sale.

·The derivative liability and warrant liability are classified as fair value through profit or loss.

Fair values

The financial assets and liabilities that are recognized on the balance sheet at fair value are in grouped into three Levels of a hierarchy based on the observability of significant inputs used in making the measurements, as follows:

Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company can assess at the measurement date;

Level 2 — Inputs other than quoted prices included in Level 1 that are observable for the asset or liability either

directly as prices or indirectly derived from prices; and

Level 3 — Inputs for the asset or liability that are not based on observable market data.

The following table shows the Levels within the hierarchy of financial assets and liabilities measured at fair value on a recurring basis at December 31, 2014:

Liquidity risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they fall due. The Company manages liquidity risk by forecasting its cash flows from operations and anticipating investing and financing activities. Senior management is actively involved in the review and approval of planned expenditures. Management believes that the ability to fund operations through cash generated from operations should be sufficient to meet the ongoing capital and operating requirements.

During the year ended December 31, 2014, the Company generated operating cash flows from continuing operations of $110,860 (December 31, 2013 — $78,479). At December 31, 2014, the Company held cash and cash equivalents of $48,165 (December 31, 2013 — $27,077) and working capital of $9,086 (December 31, 2013 — $48,150), which the Company defines as current assets less current liabilities. The Company held no money market investments with terms greater than 90 days at December 31, 2014 and 2013.

In July, 2014, the Company received funds of $35,000, as part of a $50,000 credit facility agreement as discussed in Note 19.

For the periods beyond 2014, the Company’s cash flows from operations and available funding under the Company’s loan and credit facilities are expected to sufficiently support further expansion and growth.

Credit risk

Credit risk is the risk that a counterparty fails to discharge an obligation to the Company. The Company’s credit risk is primarily attributable to its liquid financial assets, including cash and cash equivalents, restricted cash and accounts receivable. The Company limits its exposure to credit risk by maintaining its cash and cash equivalents, and restricted cash with high-credit quality financial institutions, selling to reputable customers and insuring shipments with reputable underwriters. Management considers the credit risk to the Company to be minimal.

The Company’s maximum exposure to credit risk is as follows:

	December 31, 2014		December 31, 2013
Cash and cash equivalents	$	48,165	$	27,077
Restricted cash	5,014		4,027
Accounts receivable	2,687		30,197
	$	55,866	$	61,301

Currency risk

The Company operates in Canada, Peru and Barbados and is exposed to foreign exchange risk arising from transactions denominated in foreign currencies.

The operating results and the financial position of the Company are reported in United States dollars. Fluctuations of the operating currencies in relation to the United States dollar will have an impact upon the reported results of the Company and may also affect the value of the Company’s assets and liabilities.

The Company’s financial assets and liabilities are denominated in United States, Canadian dollars and Peruvian Sol as set out in the following table:

Net financial assets (liabilities)	$	12,034	$	1,890	$	(42,095	)	$	(28,171	)

The Company’s reported results will be affected by changes in the US dollar to Canadian dollar and US dollar to Sol exchange rate. As of December 31, 2014, a 10 per cent appreciation of the Canadian dollar relative to the US dollar would have decreased net financial assets by approximately $189. A 10 per cent depreciation of the US dollar relative to the Canadian dollar would have had the equal but opposite effect. A 10 per cent appreciation of the Sol relative to the US dollar would have decreased net financial assets by approximately $4,210 and a 10 per cent depreciation of the Sol would have had an equal but opposite effect.

The Company has not entered into any agreements or purchased any instruments to hedge possible currency risk.

Interest risk

The Company invests its cash in instruments that are redeemable at any time without penalty, thereby reducing its exposure to interest rate fluctuations.

The Company borrowed $3,000 in September 2011 bearing annual interest at 3-month LIBOR plus 6%. The $3,000 loan and accrued interest of $584 were repaid in full in July 2014.

In July 2014, the Company received funds of $35,000 from BCP Banco de Credito del Peru (“BCP”). The loan has a one-year term and bears annual interest at 30-day LIBOR plus 2.60%. The funds will be used for working capital.

As of December 31, 2014, a 1% change in the interest rate would not have changed the value of the debt as all accrued interest had been paid. Other interest rate risk arising from the Company’s operations are not considered material.

Commodity price risk

Commodity price risk is the risk that the fair value or future cash flows of the Company’s financial instruments will fluctuate because of changes in market prices. There has been no change in the Company’s objectives and policies for managing this during the year ended December 31, 2014. During the year ended December 31, 2014, the Company completed the commitments under the Purchase Agreement (Note 17).

The Company is exposed to price risk with respect to commodity prices. The ability of the Company to develop its mineral properties and future profitability of the Company are directly related to the market price of gold and copper. The Company monitors commodity prices to determine whether changes in operating or development plans are necessary. Future gold production is un-hedged in order to provide shareholders with full exposure to changes in the market gold price.

33.SUBSEQUENT EVENTS

a.Subsequent to December 31, 2014, the Company received $1,013 pursuant to the exercise of 708,875 stock options.

b.Subsequent to December 31, 2014, the Company received $2,105 pursuant to the exercise of 1,050,000 warrants.

c.On January 29, 2015, the Company completed the sale-leaseback of the La Ramada power substation, property of Empresa de Energia Yamobamba SAC, for proceeds of US $20 million with a corresponding increase in the Company’s debt in the form of a capital lease.

d.On February 9, 2015, the Company and Tahoe Resources Inc. announced that they have entered into a definitive agreement (the “Arrangement Agreement”) to combine their respective businesses (the “Rio-Tahoe Transaction”) and create a new, leading intermediate precious metals producer with several value-enhancing growth opportunities.

Under the terms of the Arrangement Agreement, all of the Rio Alto issued and outstanding common shares will be exchanged on the basis of 0.227 of a Tahoe common share and C$0.001 in cash per Rio Alto share (“Exchange Ratio”). Upon completion of the Rio-Tahoe Transaction, existing Tahoe and Rio Alto shareholders will own approximately 65 percent and 35 percent of the combined company, respectively.

Based on the closing price of Tahoe’s common shares on the Toronto Stock Exchange (TSX)  of C$17.64 on February 6, 2015, the offer implies consideration of C$4.00 per Rio Alto share which represents a premium of 22.1 percent to the closing price of Rio Alto shares of C$3.28 on the TSX on February 6, 2015 and a premium of 20.3 percent based on the volume weighted average prices of each respective company on the TSX for the 20-day period ending on February 6, 2015.

The Arrangement Agreement includes customary deal-protection provisions including non-solicitation provisions, a right to match competing offers and a C$57.6 million termination fee payable to Tahoe under certain circumstances.

Full details of the Rio-Tahoe Transaction have been included in Rio Alto’s Notice of Special Meeting and Management Proxy and Information Circular filed on March 5, 2015. The Special Meeting of Rio Alto’s shareholders will be held on March 30, 2015.

Notes to the Condensed Interim Consolidated Financial Statements

For the three months ended March 31, 2015 and 2014

(Unaudited - Expressed in thousands of United States dollars, except for per share and per ounce amounts)

1.NATURE OF OPERATIONS

Rio Alto Mining Limited (“Rio Alto” or the “Company”) is the parent company of a consolidated group. Rio Alto Mining Limited is incorporated under the laws of the Province of Alberta, with its registered office at Suite 1000 - 250 2nd Street S.W., Calgary, Alberta, T2P 0C1 and its head office at Suite 1950 - 400 Burrard Street, Vancouver, BC, V6C 3A6. The Company’s wholly-owned subsidiary La Arena S.A. (“La Arena”) owns the La Arena mineral project (“La Arena Project”) in Peru. The La Arena Project has two separate deposits, a gold oxide deposit (“Phase I”) and a copper/gold sulphide deposit (“Phase II”), and several exploration prospects. Phase I is in production and a feasibility study on the economic viability of developing Phase II is underway.

2.BASIS OF PREPARATION

These condensed interim consolidated financial statements are prepared in accordance with IAS 34 Interim Financial Reporting. They do not include all of the information required for annual financial statements and should be read in conjunction with the consolidated financial statements for the year ended and as at December 31, 2014, which are available at www.sedar.com.

The accounting policies used for the preparation of these condensed interim consolidated financial statements are the same as those expected to be used to prepare the consolidated financial statements for the year ended December 31, 2014. As part of the acquisition of the Company subsequent to March 31, 2015, it is possible that certain accounting policies will need to be reconciled to Tahoe’s accounting policies. Management does not expect these changes to be material.

These condensed interim consolidated financial statements are presented in United States dollars (“USD”), which is the functional currency of the Company and its material subsidiaries.

These condensed interim consolidated financial statements were approved by Kathryn Johnson, Chief Financial Officer of the Company during the three months ended March 31, 2015, and currently Director of Finance of Tahoe Resources Inc., on June 1, 2015.

3.SIGNIFICANT JUDGMENTS, ESTIMATES AND ASSUMPTIONS

When preparing interim financial statements, management makes a number of judgments, estimates and assumptions in the recognition and measurement of assets, including mineral properties, liabilities, income and expenses. Actual financial results may not equal the estimated results due to differences between estimated or anticipated events and actual events. The judgments, estimates and assumptions made in the preparation of these condensed interim consolidated financial statements were similar to those made in the preparation of the Company’s annual financial statements for the year ended December 31, 2014. The only significant exception is the estimate of the provision for income taxes, which is determined in these interim financial statements by using the estimated average annual effective income tax rates applied to the pre-tax income of the interim period.

4.SIGNIFICANT ACCOUNTING POLICIES

a.Basis of consolidation

Subsidiaries are entities over which the Company directs the financial and operating policies of the entity and expects to obtain benefits from its activities.

5.SHAHUINDO ACQUISITION

On August 5, 2014, Rio Alto acquired all of the outstanding shares of Sulliden Gold Corporation Ltd. (“Sulliden”) in exchange for 0.525 shares (“exchange ratio”) of Rio Alto common stock for each outstanding common share of Sulliden, excluding the 26,966,292 common shares of Sulliden already held by Rio Alto as described in Note 8. The Transaction was accounted for as an acquisition of assets. The primary asset of Sulliden was the Shahuindo Gold Project in Peru.

In addition to the 151,694,886 shares of Rio Alto issued in exchange for the outstanding shares of Sulliden, 750,000 Deferred Share Units (“DSUs”) and 2,510,000 Restricted Share Units (“RSUs”) were settled by the issuance of 393,750 and 1,317,754 shares of Rio Alto, respectively. The acquisition purchase price reflects the opening market price of Rio Alto’s common shares on August 5, 2014, which was Canadian dollar (“CAD”) $2.54/share.

Each Sulliden warrant or stock option which gave the holder the right to acquire shares in the common stock of Sulliden was exchanged for a warrant or stock option which gave the holder the right to acquire shares in the common stock of Rio Alto on the same basis as the exchange ratio of Sulliden common shares for Rio Alto common shares. These options and warrants have been included in the purchase price at their fair value based on the Black-Scholes pricing model using the following weighted average assumptions:

	Options			Warrants
Issued	10,995,756			9,910,112
Strike price	$	2.42		$	2.39
Risk-free interest rate	1.09		%	1.06		%
Expected option life (years)	2.0			0.7
Expected price volatility	56		%	58		%

On completion of the Transaction, Sulliden shareholders received 0.10 of a common share in a newly incorporated company called Sulliden Mining Capital Inc. (“Sulliden Mining”) for each Sulliden common share held. Sulliden Mining was capitalized with CAD$25 million in cash from Rio Alto.

The purchase price has been allocated to the assets acquired and liabilities assumed based on their relative fair values on the closing date. The purchase price allocation is a result of management’s best estimates and assumptions after taking into account all relevant information available. The purchase price has been determined and allocated as follows:

Purchase price including shares owned previously:
Fair value of shares issued	$	352,650
Fair value of Sulliden shares owned previously	32,788
Fair value of shares issued to settle DSU and RSU	3,979
Fair value of stock options issued	9,083
Fair value of share purchase warrants issued	5,030
Cash	22,895
Transaction costs	6,414
Total purchase price	$	432,839
Purchase price allocation:
Cash and cash equivalents	$	8,776
Accounts receivable and prepaid expenses	2,950
IGV receivable	12,204
Plant and equipment	22,752
Mineral properties and deferred exploration costs	388,018
Accounts payable and accrued liabilities	(1,861		)
Net assets acquired	$	432,839

(Unaudited - Expressed in thousands of United States dollars, except for per share and per ounce amounts)

b.Sulliden Mining Capital

On completion of the Transaction, Sulliden shareholders received 0.10 of a common share in a newly incorporated company called Sulliden Mining Capital Inc. (“Sulliden Mining”) for each Sulliden common share held. As a result, Rio Alto received 2,696,629 shares of Sulliden Mining. On the date of the Transaction, the fair value of the Sulliden shares, net of the fair value of the Sulliden Mining shares received, formed part of the purchase price of the assets acquired in the Transaction (Note 5). Sulliden Mining was capitalized with CAD$25 million in cash from Rio Alto. Sulliden Mining holds a 100% interest in the East Sullivan Property in Val-d’Or, Quebec.

c.Santa Barbara

In February 2013, the Company purchased 2,500,000 common shares of Santa Barbara at a price of CAD$0.08 per share, for total consideration of CAD$200.

d.Duran

The Company holds 5,000,000 units of Duran. The units consist of one common share of Duran and one half of a Series A Warrant and one half of a Series B Warrant (the “Duran Units”).

All the Series A Duran Ventures Warrants held by the Company expired unexercised on December 31, 2014.

All the Series B Warrants expired unexercised on March 28, 2015.

Subject to the performance of certain conditions, Rio Alto may earn up to a 70% interest in Duran’s Minasnioc Gold-Silver Property (“Minasnioc”) and a 65% interest in Duran’s Ichuña Copper-Silver Property (“Ichuña”). In order to complete its earn-in option for the Minasnioc and Ichuña properties, Rio Alto must convert 100% of the warrants included in the Duran Units.

In June 2013, Rio Alto decided to terminate the Ichuña option. In November 2014, Rio Alto decided to terminate the Minasnioc option.

14.INCOME TAXES PAYABLE

Taxes payable consist of the following:

	March 31, 2015			December 31, 2014
Special mining tax	$	2,173		$	1,706
Royalty	2,268			1,902
Income taxes payable (receivable)	(429		)	203
	$	4,012		$	3,811

Income taxes payable consists of the income tax obligation arising from taxes and a royalty imposed by Peruvian tax authorities, less tax instalments paid during the year and recognition of an increase in the deferred tax asset. The Company has obtained legal and other independent advice in determination of its tax liability. There can be no assurance that the tax authority will concur with such determination and may assess the Company for additional taxes.

During the three months ended March 31, 2015, the following tax payments were made:

	Related to 2014		Related to 2015		Total
Special mining tax	$	848	$	—	$	848
Royalty	$	837	$	—	$	837
Income tax	$	3,237	$	5,443	$	8,680
	$	4,922	$	5,443	$	10,365

The Company recognized a deferred tax asset (liability) comprised of:

15.DEFERRED REVENUE AND DERIVATIVE LIABILITY

In 2011, the Company received $50,000 under a Gold Prepayment Agreement (“Prepayment”) and simultaneously entered into an off take agreement — the Gold Purchase Agreement (“Purchase Agreement”). The proceeds of the Prepayment were to partially fund development of Phase I. The Purchase Agreement includes a derivative liability (written option). An option pricing model that considers gold volatility is used to estimate the fair value of the derivative liability. Drawdowns of the Prepayment were initially apportioned to derivative liability based on estimated fair value with the residual amount allocated to deferred revenue.

(Unaudited - Expressed in thousands of United States dollars, except for per share and per ounce amounts)

a.Deferred revenue consists of:

	March 31, 2015		December 31, 2014
Opening balance	$	—	$	8,040
Cash settlement of deferred revenue	—		—
Deliveries to recognize deferred revenue	—		(8,040		)
Ending balance	$	—	$	—

Under the Prepayment, the Company was committed to deliver a notional amount of 1,941 ounces of gold each month until October 2014. Once the accumulated monthly deliveries total 61,312 notional ounces of gold, the Prepayment is settled. The actual monthly delivery of gold ounces may vary by 5 per cent from 1,941 ounces for every $100 dollar change in the gold price from a base price of $1,150 per ounce, subject to limits at $1,450 and $950 per ounce. At a price of $1,450 or more the monthly delivery would be 85 per cent of 1,941 ounces and 115 per cent of 1,941 ounces if the price of gold was $950 or less.

The Company had the option to prepay gold ounces remaining to be delivered under the Prepayment, in whole or in part, at any time without penalty in either ounces of gold or the equivalent in cash at the then prevailing gold price. In April 2013, the Company made a one-time cash payment of $10,057 to settle 7,882 notional ounces to be delivered under the Prepayment. The price per ounce embedded in the Prepayment was lower than the price of gold when the cash payment was made. As a result, only the price per ounce embedded in the Prepayment was recognized as a deferred revenue fulfillment. The cash payment of $10,057 reduced the deferred revenue balance by $4,630 while the $5,427 balance was recorded as a loss on the settlement of the Prepayment.

The remaining committed ounces were settled in July 2014.

b.Derivative liability consists of:

	March 31, 2015		December 31, 2014
Opening balance	$	—	$	734
Change in fair market value of derivative liability	—		(734		)
Ending balance	$	—	$	—

Under the Purchase Agreement the Company granted an option that allows the holder to purchase gold produced from two oxide pits (the Calaorco pit and the Ethel pit) up to an estimated amount of 634,000 ounces. The option holder may elect to pay one of either the London Gold Market AM Fixing Price or the Comex (1st Position) Settlement Price over predetermined periods of time. The option holder’s election represents an embedded derivative and is accounted for as a written call option. Changes in the fair value of the liability are reflected in profit or loss.

In the fourth quarter of 2014, the Company delivered the final estimated remaining ounces owing under the obligation. Subsequent to delivering the final estimated remaining ounces owing under the obligation, the Company was informed by the option holder that the option holder was in disagreement with the Company’s conclusion that the total obligation had been fulfilled. As more particularly described in the 2015 Technical Report, the gold mineral resources and mineral reserves of the body of gold oxide mineralization within the Calaorco pit described in the 2010 Report have increased, while the Ethel pit has been exhausted through mining. As a result of the increased gold mineral resources and mineral reserves, the contracting parties are working together to reach an agreed upon interpretation of the Gold Purchase Agreement. Management cannot, at this time, reasonably estimate the number of ounces, if any, that the Company will be obligated to deliver to the counterparty over and above the 634,000 ounces already delivered through October 2014. In the interim, Rio Alto has voluntarily re-commenced delivery of gold produced from the Calaorco pit to the counterparty with a view to reaching an agreement regarding the interpretation of the Gold Purchase Agreement.

16.WARRANT LIABILITY

The warrant liability consists of the following:

	Warrants (000’s)		Exercise Price (CAD$/warrant)		Warrant liability

Balance March 31, 2015	8,860		$	2.39	$	5,103

The Black-Scholes Option Pricing Model is used to estimate the fair value of options granted and changes in the fair value of the liability are reflected in profit or loss. During the three months ended March 31, 2015, 1,050,000 warrants were exercised for proceeds of $2,098.

The remaining warrants were replaced for Tahoe Warrants on closing of the Tahoe Acquisition. All outstanding warrants were exercised prior to the expiration date of April 12, 2015.

17.DEBT

The Company borrowed $3,000 in September 2011 bearing annual interest at LIBOR plus 6%. The debt matured in October 2014. As security for the Prepayment and the $3,000 loan, the Company granted a charge over its shares of La Arena and substantially all of the Company’s assets. The $3,000 loan and accrued interest of $584 were repaid fully in July 2014.

In July 2014, the Company received funds of $35,000 from Banco de Credito del Peru, as part of the $50,000 credit facility agreement signed on June 16, 2014. The loan has a one-year term and bears interest at 30-day LIBOR plus 2.60%. The funds will be used for working capital. As security for this loan, the Company granted a charge over the shares of its subsidiary Empresa de Energia Yamobamba SAC and the rights of collection and future flows derived from the sale of concentrates of minerals or other products from La Arena mine.

18.SALE AND LEASEBACK TRANSACTION

The La Ramada sub-station, property of Empresa de Energia Yamobamba SAC (“Yamobamba”), was commissioned at the end of October 2014 (the “asset”). On January 29, 2015 the asset was sold to the BCP for $20,705 and it was immediately leased back for an amount equal to the selling price. The sale and leaseback transaction was denominated in Soles.

At the time of sale, the asset had a carrying value of $20,791. The loss of $86 on the asset sale has been recognized on the income statement for the three months ended March 31, 2015.

The lease obligation is denominated in Soles and carries an effective annual interest rate of 6.95%. The term of the lease is 3 years with quarterly instalments consisting of principal plus interest plus IGV. The maturity of the lease is February 1, 2018, and there is a purchase option for 3,000 Soles at the end of the lease.

Concurrent with the sale and leaseback transaction, Yamobamba entered into a Cross Currency Swap with BCP (“Swap”) for $23,600 at a fixed exchange rate of 2.9600 Sol per USD. On January 29, 2015, Yamobamba paid 69,856,000 Soles to BCP, and Yamobamba received $23,600 from BCP.

The term of the Swap is 3 years with quarterly instalments consisting of principal plus interest. The maturity of the

Swap is February 1, 2018.

The changes in the fair value of the Swap are recognized on the statement of net (loss) income and comprehensive (loss) income as an unrealized gain or loss on the Cross Currency Swap.

As at March 31, 2015, the Cross Currency Swap had a fair value of ($1,532).

Current portion of lease obligation	6,592
Non-current portion of lease obligation	12,748
Lease obligation, March 31, 2015	$	19,340

In connection with the sale and leaseback transaction for the La Ramada substation, La Arena S.A. has signed as guarantor for the lease obligation entered between Yamobamba and BCP. As part of its guarantee, La Arena S.A. is subject to the following covenants, calculated quarterly, in accordance with financial information for the most recently completed twelve month period.

1.Maintain a “debt service ratio” of at least 1.20. This ratio is defined as the cash flows for debt service divided by the debt service. The cash flows for debt service are defined as EBITDA less Income Tax less Capex additions net of long-term financing to finance such additions. The debt service is defined as the sum of La Arena’s interest expenses plus principal repayment, plus the interest expense and principal repayment of the La Ramada lease obligation.

2.Maintain a “remaining life of mine ratio” of at least 1.40. This ratio is defined as the remaining life of mine for La Arena divided by the remaining term of the lease obligation. The remaining life of mine is defined as the Proven and Probable Reserves in accordance with the NI 43-101 technical report divided by the gold production of the last twelve months.

19.ASSET RETIREMENT OBLIGATION

Asset retirement obligation consists of:

	March 31, 2015		December 31, 2014

	$	28,988	$	24,139

The Company’s original reclamation and closure plan for La Arena was filed with Peru’s Ministry of Energy and Mines in October 2012.

The Company submitted an updated reclamation and closure plan for La Arena in the first quarter of 2015. Peru’s Ministry of Energy and Mines issued its approval in March 2015. An adjustment in the amount of $4,427 was recognized in March 2015 to reflect the changes in the estimated fair value measurements which resulted in a corresponding change to the carrying values of the related asset, in this case, La Arena Phase I mineral property.

Assumptions used in determining the Company’s asset retirement obligations at March 31, 2015 include an inflation

23.FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

The Company’s financial instruments consist of cash and cash equivalents, restricted cash, accounts receivable, other financial assets, accounts payable and accrued liabilities, long-term debt, warrant liability, lease obligation and cross currency swap derivative liability.

Cash and cash equivalents, restricted cash, and accounts receivable, are classified as loans and receivables and measured at amortized cost. Other financial assets are classified as fair value through profit or loss, except for the Sulliden Mining shares which are classified as available-for-sale. Accounts payable and accrued liabilities, long-term debt and lease obligation are classified as other financial liabilities. The cross currency swap derivative liability and warrant liability are classified as fair value through profit or loss.

Fair values

The financial assets and liabilities that are recognized on the balance sheet at fair value are in a hierarchy that is based on significance of the inputs used in making the measurements. The levels in the hierarchy are:

Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company can assess at the measurement date;

Level 2 — Inputs other than quoted prices included in Level 1 that are observable for the asset or liability either directly as prices or indirectly derived from prices; and

Level 3 — Inputs for the asset or liability that are not based on observable market data.

Liquidity risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they fall due. The Company manages liquidity risk by forecasting its cash flows from operations and anticipating investing and financing activities. Senior management is actively involved in the review and approval of planned expenditures. Management believes that the ability to fund operations through cash generated from operations should be sufficient to meet the ongoing capital and operating requirements. At March 31, 2015, the Company’s working capital of $10,907 was sufficient to meet its short-term business requirements.

Credit risk

The Company’s credit risk is primarily attributable to its liquid financial assets and doré and would arise from the non-performance by counterparties of contractual financial obligations. The Company limits its exposure to credit risk on liquid assets by maintaining its cash with high-credit quality financial institutions and shipments of doré are insured with reputable underwriters. Management believes the risk of loss of the Company’s liquid financial assets and doré to be minimal.

The Company’s maximum exposure to credit risk is as follows:

	March 31, 2015		December 31, 2014
Cash and cash equivalents	$	61,713	$	48,165
Restricted cash	—		5,014
Accounts receivable	768		2,687
	$	62,481	$	55,866

Currency risk

The Company operates in Canada, Peru and Barbados and is exposed to foreign exchange risk arising from transactions denominated in foreign currencies.

The operating results and the financial position of the Company are reported in USD. Fluctuations of the operating currencies in relation to the USD will have an impact upon the reported results of the Company and may also affect the value of the Company’s assets and liabilities.

(Unaudited - Expressed in thousands of United States dollars, except for per share and per ounce amounts)

The Company’s financial assets and liabilities as at March 31, 2015 are denominated in USD, CAD and Soles set out in the following table:

	USD		CAD		Sol			Total
Financial assets
Cash and cash equivalents	$	56,704	$	875	$	4,134		$	61,713

Net financial assets (liabilities)	$	8,622	$	983	$	(51,364	)	$	(41,759	)

The Company’s reported results will be affected by changes in the USD to CAD and USD to Sol exchange rate. As of March 31, 2015, a 10 per cent appreciation of the CAD relative to the USD would have decreased net financial assets by approximately $98. A 10 per cent depreciation of the USD relative to the CAD would have had the equal but opposite effect. A 10 per cent appreciation of the Sol relative to the USD would have decreased net financial assets by approximately $5,136 and a 10 per cent depreciation of the Sol would have had an equal but opposite effect.

Interest risk

The Company invests its cash in instruments that are redeemable at any time without penalty, thereby reducing its exposure to interest rate fluctuations.

In July 2014, the Company received funds of $35,000 from BCP Banco de Credito del Peru (“BCP”). The loan has a one-year term and bears annual interest at 30-day LIBOR plus 2.60%.

In January 2015, the Company entered into a sale-leaseback transaction with BCP for $20,705. The lease obligation is denominated in Soles and carries an effective annual interest rate of 6.95%. The term of the lease is 3 years with quarterly instalments. The maturity of the lease is February 1, 2018.

Other interest rate risks arising from the Company’s operations are not considered material.

Commodity price risk

Commodity price risk is the risk that the fair value or future cash flows of the Company’s financial instruments will fluctuate because of changes in market prices. There has been no change in the Company’s objectives and policies for managing this risk since December 31, 2014.

The Company is exposed to price risk with respect to commodity prices. The ability of the Company to develop its mineral properties and future profitability of the Company are directly related to the market price of gold and copper.

NOTES TO THE PRO FORMA

CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited - Expressed in Thousands of United States Dollars, Except as Otherwise Stated)

For The Three Months Ended March 31, 2015 and The Year Ended December 31, 2014

1.DESCRIPTION OF THE TRANSACTION

The accompanying unaudited pro forma condensed consolidated financial statements of Tahoe Resources Inc. (“Tahoe”) have been prepared to give effect to the closing of the arrangement agreement entered into by Tahoe, 1860927 Alberta Ltd. and Rio Alto Mining Limited (“Rio Alto”) dated February 9, 2015 (the “Arrangement Agreement”) pursuant to which Tahoe directly acquired 100% of Rio Alto by way of a plan of arrangement on April 1, 2015 (the “Acquisition”).

Pursuant to the Acquisition, Rio Alto shareholders exchanged all issued and outstanding common shares for common shares of Tahoe at a ratio of one Rio Alto common share per 0.227 of one Tahoe common share and a nominal cash payment of CAD$0.001 per Rio Alto common share. The total transaction consideration paid to common shareholders of Rio Alto was approximately $272 in cash, and approximately $873,464 in aggregate value of common shares of Tahoe and replacement warrants and options, based on the opening price of Tahoe common shares on the Toronto Stock Exchange (“TSX”) of CAD$14.21 on April 1, 2015. The transaction consideration under the Acquisition is equal to CAD$3.23 per Rio Alto common share on a fully diluted basis based on the opening price of the Tahoe shares on the TSX on April 1, 2015.

2.BASIS OF PREPARATION

The unaudited pro forma consolidated statement of operations for the year ended December 31, 2014 combines the historical consolidated statements of operation of Tahoe and Rio Alto for the year ended December 31, 2014, to give effect to the Acquisition as if it had occurred on January 1, 2014. The unaudited pro forma consolidated statement of operations for the three months ended March 31, 2015 combines the unaudited historical consolidated statement of operation of Tahoe and the unaudited consolidated statement of operation of Rio Alto for the three months ended March 31, 2015 (note 3), to give effect to the Acquisition as if it had occurred on January 1, 2014. The unaudited pro forma consolidated statement of financial position as at March 31, 2015 combines the historical consolidated statement of financial position of Tahoe and the unaudited consolidated statement of financial position of Rio Alto (note 3), as at that date, to give effect to the Acquisition as if it had occurred on March 31, 2015.

The unaudited pro forma consolidated condensed financial statements were based on and should be read in conjunction with the following:

·Audited consolidated financial statements of Tahoe as at and for the year ended December 31, 2014 and the accompanying notes;

6

NOTES TO THE PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited - expressed in 000’s of USD, except as otherwise stated)

·Audited consolidated financial statements of Rio Alto as at and for the year ended December 31, 2014 and the accompanying notes;

·Unaudited condensed consolidated interim financial statements of Tahoe for the three months ended March 31, 2015 and the accompanying notes; and

·Unaudited condensed consolidated interim financial statements of Rio Alto for the three months ended March 31, 2015 and the accompanying notes.

The historical consolidated financial statements of Rio Alto have been adjusted to give effect to the following pro forma events:

·Those that are directly attributable to the Acquisition;

·Those that are factually supportable; and

·Those with respect to the pro forma consolidated statements of operations, expected to have a continuing impact on the consolidated results.

The unaudited pro forma condensed consolidated financial statements have been presented for informational purposes only. The pro forma information is not necessarily indicative of what Tahoe’s financial position or financial performance actually would have been had the Acquisition been completed as of the dates indicated and does not purport to project the future financial position or operating results of Tahoe.

The unaudited pro forma condensed consolidated financial statements have been derived from financial statements prepared in accordance with historical International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS”) effective as of December 31, 2014.

The Acquisition is considered to be a business combination under IFRS 3 — Business combinations (“IFRS 3”). The unaudited pro forma condensed consolidated financial statements have been prepared using the acquisition method of accounting in accordance with IFRS 3. Accordingly, the purchase price calculation and purchase price allocation are dependent upon fair value estimates and assumptions as at the acquisition date. In certain instances adequate information is not available at the time of the preparation of these unaudited pro forma condensed consolidated financial statements to perform a final estimate of fair value. Tahoe will finalize all amounts as it obtains the information necessary to complete the measurement process, which, pursuant to IFRS 3, can be no later than one year from the acquisition date. Accordingly, certain pro forma adjustments contained herein are preliminary and have been made solely for the purpose of providing unaudited pro forma condensed consolidated financial statements. Differences between preliminary estimates and final amounts may occur and these differences could be material to the accompanying unaudited pro forma condensed consolidated financial statements of Tahoe and Tahoe’s future performance and financial position.

These unaudited pro forma condensed consolidated financial statements are presented for illustrative purposes only and do not reflect the additional savings or costs that may result from the transaction. There can be no assurance that cost savings and synergies will be achieved. Similarly, no amounts have been included in the purchase price allocation for the estimated costs to be incurred to achieve savings or other benefits of the transaction.

3.HISTORICAL RIO ALTO CONSOLIDATED FINANCIAL STATEMENTS

The historical audited consolidated financial statements of Rio Alto for the year ended December 31, 2014 has not been adjusted to give effect to the acquisition of Sulliden Gold Corporation Limited (“Sulliden”) which occurred in August 5, 2014. Rio Alto’s historical financial information does not give pro forma effect to the Sulliden acquisition because Rio Alto has consolidated the results of Sulliden since the date of the acquisition and as the pro forma impact of the seven-month period beginning January 1, 2014 through July 31, 2014 was determined to not be material. The operations of Sulliden have been included in Rio Alto’s operations from that date.

4.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

These unaudited pro forma condensed consolidated financial statements have been compiled using the significant accounting policies as set out in the audited consolidated financial statements of Tahoe as at and for the years ended December 31, 2014 and 2013 and the unaudited consolidated financial statements of Tahoe as at and for the three months ended March 31, 2015. Management has determined, based on their initial assessment, that no adjustments are necessary to conform the relevant items of Rio Alto’s financial statements to the accounting policies used by Tahoe in the preparation of its financial statements.

5.PURCHASE PRICE ALLOCATION

The activity of Rio Alto constitutes a business, as defined by IFRS 3, and consequently, Tahoe has applied the principles of IFRS 3 in the accounting for the acquisition 100% of the issued and outstanding common shares of Rio Alto.

A summary of the fair value of the purchase price for the acquired assets and liabilities assumed is as follows:

Tahoe purchase consideration:
Fair value estimate of the Tahoe share consideration	$	856,198
Fair value estimate of the consideration for warrants	5,837
Fair value estimate of the consideration for options	11,429
Cash consideration	272
Total purchase consideration	$	873,736

The purchase price consideration reflects the number of outstanding shares and Rio Alto shares issuable upon the exercise of outstanding Rio Alto options and warrants as at April 1, 2015. For purposes of pro forma presentation, all issued and outstanding warrants and options (vested and unvested) exercisable of Rio Alto at the Acquisition date were converted into warrants and options of Tahoe. Fair value assumptions used are disclosed in note 6.

8

NOTES TO THE PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited - expressed in 000’s of USD, except as otherwise stated)

The preliminary purchase price allocation to the following identifiable assets and liabilities is based on their estimated fair values as of April 1, 2015.

	Preliminary Allocation
Cash and cash equivalents	$	61,713
Other current and non-current assets	88,242
Mineral interests	1,079,285
Current liabilities	(94,593		)
Reclamation provision	(28,988		)
Other long-term liabilities	(19,280		)
Deferred tax liability	(212,643		)
Total net assets acquired	$	873,736

The estimate of the fair value of mineral interests is preliminary, however, and is subject to change. The final purchase price allocation and the fair value of the net assets acquired will ultimately be determined within 12 months of the Acquisition date. Therefore, it is likely that the fair values of assets acquired and liabilities assumed will vary from those shown above. The actual fair value of the assets and liabilities may differ materially from the amounts disclosed above in the preliminary pro forma purchase price allocation because of changes in fair values, as further analysis is completed.

6.PRO FORMA ASSUMPTIONS AND ADJUSTMENTS

The unaudited pro forma condensed consolidated financial statements reflect the following assumptions and adjustments to give effect to the Acquisition, as if the Acquisition had occurred on March 31, 2015 for the consolidated statement of financial position items and January 1, 2014 for the consolidated statement of operations items for the three months ended March 31, 2015 and for the consolidated statement of operations items for the year ended December 31, 2014. Assumptions relating to the opening share price of Tahoe for the purposes of determining the consideration are based on the opening share price of the date of Acquisition of April 1, 2015. Assumptions and adjustments made are as follows:

a)An adjustment to reflect the issuance of 75,991,381 Tahoe shares, based on a ratio of 0.227 of a Tahoe common share for each outstanding Rio Alto share. The opening price of Tahoe shares on the TSX on April 1, 2015 was CAD$14.21 for total consideration of $856,198. The Rio Alto share capital balance of $507,707 was eliminated for a net adjustment of $348,491;

b)An adjustment to assume the issuance of 2,011,245 Tahoe shares, based on a ratio of 0.227 of a Tahoe common share for each outstanding Rio Alto warrant exercised. The fair value of the warrants of $5,837(1) was determined using the Black-Scholes valuation model. The Rio Alto warrant liability of $5,103 at March 31, 2015 was eliminated for a net adjustment of $734;

c)An adjustment to reflect the issuance of 3,374,449 Tahoe replacement options, based on a ratio of 0.227 of a Tahoe common share for each outstanding Rio Alto option exercised. The fair value of the options was determined using the Black-Scholes valuation model for total consideration of $11,429(1). The Rio Alto equity reserve balance of $19,743 was eliminated for a net adjustment of $8,314;

9

NOTES TO THE PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited - expressed in 000’s of USD, except as otherwise stated)

d)The remaining equity balances of Rio Alto have been eliminated which include $3,289 in other comprehensive income and $142,866 in earnings. Other pro forma adjustments include an additional negative impact of $12,242 to retained earnings for a net adjustment of $155,108;

e)An adjustment to reflect the fair value of inventories held by Rio Alto. The fair value of product inventory was adjusted by $23,077 to reflect the ounces held in inventory at the spot price of gold on March 31, 2015, of $1,187/oz less estimated refining and transportation costs of $5 per ounce;

f)An adjustment to reflect the fair value of mineral interest held by Rio Alto of $1,079,285. As the book value of mineral interests of Rio Alto is $692,910, there is a net adjustment of $386,375;

g)An adjustment to reflect the accrual of the cash consideration of CAD$0.001 per Rio Alto share totaling CAD$344 ($272), remaining transaction costs of $4,559 and change of control costs of $8,934 to accounts payable and accrued liabilities;

h)An adjustment to other long-term liabilities to reflect $3,750 in estimated additional acquisition related costs;

i)A long term deferred tax liability of $212,643 related to the excess purchase price consideration and fair market value adjustments has been recognized and will be reversed through income as the underlying asset is consumed. The Rio Alto deferred tax liability of $3,220 was eliminated for a net adjustment of $209,423;

j)Adjustments of $5,721 and $21,615 for the three months ended March 31, 2015 and the year ended December 31, 2014, respectively, to reflect the additional depreciation and depletion incurred on the depletable assets acquired and the related tax effects at the statutory rates of $1,602 and $6,052, for the three months ended March 31, 2015 and year ended December 31, 2014, respectively; and

k)An adjustment to remove transaction costs of $20,085 included in the Rio Alto March 31, 2015 statement of operations during the three months ended March 31, 2015.

(1)The inputs and input ranges, where applicable, used in the measurement of the fair value (CAD$) of the Options and Warrants at the Acquisition date are as follows:

	Options			Warrants
Share price (CAD$)	$	14.21		$	14.21
Exercise price (CAD$)	$	6.13-23.13		$	10.55

Fair value (CAD$)	$	0.49-7.98		$	3.66
CAD$ to USD$ exchange rate	$	0.7929		$	0.7929
Fair value (USD$)	$	0.39-6.33		$	2.90

7.PRO FORMA INCOME TAXES

Current tax expense includes the expected tax payable on the taxable income for the period, a royalty imposed by Peruvian tax authorities, and a special mining tax (“SMT”) in Peru. The SMT and royalty have been accounted for as an income tax under IAS 12 — Income taxes. Amounts were calculated using rates substantively enacted at period end, adjusted for amendments to tax payable with regards to previous years.
