Description of Business and Nature of Operations	1. Description of Business and Nature of Operations Wheaton Precious Metals Corp. is a precious metal streaming company which generates its revenue primarily from the sale of precious metals (gold, silver and palladium) and cobalt. Wheaton Precious Metals Corp. (“Wheaton” or the “Company”), which is the ultimate parent company of its consolidated group, is incorporated and domiciled in Canada, and its principal place of business is at Suite 3500 - 1021 West Hastings Street, Vancouver, British Columbia, V6E 0C3. The Company trades on the Toronto Stock Exchange (“TSX”), the New York Stock Exchange (“NYSE”) and the London Stock Exchange (“LSE”) under the symbol WPM. As of June 30, 2023, the Company has 29 long-term purchase agreements (three of which are early deposit agreements), with 23 different mining companies, for the purchase of precious metals and cobalt (“precious metal purchase agreements” or “PMPA”) relating to 19 mining assets which are currently operating, 13 which are at various stages of development and 4 which have been placed in care and maintenance or have been closed, located in 13 countries. Pursuant to the PMPAs, Wheaton acquires metal production from the counterparties for an initial upfront payment plus an additional cash payment for each ounce or pound delivered which is either a fixed price or fixed percentage of the market price by contract, generally at or below the prevailing market price. The condensed interim consolidated financial statements of the Company for the three and six months ended June 30, 2023 were authorized for issue as of August 10, 2023 in accordance with a resolution of the Board of Directors.

Basis of Presentation and Statement of Compliance	2. Basis of Presentation and Statement of Compliance These unaudited condensed interim consolidated financial statements have been prepared on a historical cost basis, except for certain financial instruments which have been measured at fair value as at the relevant balance sheet date. The consolidated financial statements are presented in United States (“US”) dollars, which is the Company’s functional currency, and all values are rounded to the nearest thousand US dollars (US$ 000’s) unless otherwise noted. References to “Cdn$” refer to Canadian dollars. These unaudited condensed interim consolidated financial statements have been prepared in accordance with IAS 34, Interim Financial Reporting (“IAS 34”) as issued by the International Accounting Standards Board. The accounting policies applied in these unaudited condensed interim consolidated financial statements are based on International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”) and have been prepared using the same accounting policies and methods of application as disclosed in Note 3 to the audited consolidated financial statements for the year ended December 31, 2022 and were consistently applied to all the periods presented unless otherwise stated below. These unaudited condensed interim consolidated financial statements do not include all the information and note disclosures required by IFRS for annual consolidated financial statements and therefore should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2022. The preparation of financial statements in accordance with IAS 34 requires the use of certain accounting estimates. It also requires management to exercise judgment in applying the Company’s accounting policies. The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the financial statements, are disclosed in Note 4. In the opinion of management, all adjustments (including normal recurring adjustments) necessary to present fairly the financial position at June 30, 2023 and the results of operations and cash flows for all periods presented have been made. The interim results are not necessarily indicative of results for a full year.

New Accounting Standards Effective in 2023 Amendment to IAS 12 - Deferred Tax related to Assets and Liabilities arising from a Single Transaction The amendments to IAS 12 clarify that the initial recognition exemption does not apply to transactions in which equal amounts of deductible and taxable temporary differences arise on initial recognition. The amendments are effective for annual reporting periods beginning on or after January 1, 2023. Early application of the amendments is permitted. The amendments apply to transactions that occur on or after the beginning of the earliest comparative period presented. In addition, at the beginning of the earliest comparative period the following would be recognized: · a deferred tax asset to the extent that it is probable that taxable profit will be available against which the deductible temporary difference can be utilized and a deferred tax liability for all deductible and taxable temporary differences associated with right-of-use · the cumulative effect of initially applying the amendments as an adjustment to the opening balance of retained earnings (or other component of equity, as appropriate) at that date. The implementation of this amendment did not have a material impact on the Company. Amendments to IAS 1 and IFRS Practice Statement 2 – Disclosure of Accounting policies The amendments require that an entity discloses its material accounting policy information, instead of its significant accounting policies. Further amendments explain how an entity can identify a material accounting policy. Examples of when an accounting policy is likely to be material are added. To support the amendment, the IASB has also developed guidance and examples to explain and demonstrate the application of the ‘four-step materiality process’ described in IFRS Practice Statement 2. The amendments are effective for annual reporting periods beginning on or after January 1, 2023. This amendment did not have a significant impact to the Company’s condensed interim consolidated financial statements. 3.2. Future Changes to Accounting Policies The IASB has issued the following new or amended standards: Amendment to IAS 1- The amendments to IAS 1, clarify the presentation of liabilities. The classification of liabilities as current or non-current non-current non-current Amendments to IAS 12 - International Tax Reform — Pillar Two Model Rules The amendments to IAS 12 provide a mandatory temporary exception to the requirements regarding deferred tax assets and liabilities related to pillar two income taxes (Global Minimum Tax) as well as disclosure requirements that an entity has to disclose separately its current tax expense related to Global Minimum Tax and that in periods in which Global Minimum Tax legislation is enacted or substantively enacted, but not yet in effect, an entity discloses known or reasonably estimable information that helps users of financial statements understand the entity’s exposure to Global Minimum Tax arising from that legislation. The mandatory temporary exemption is effective immediately and the disclosure requirements are effective for annual periods beginning January 1, 2023. The Company has applied this mandatory exception in the current period. Refer to Note 23 for further information on Global Minimum Tax.

Key Sources of Estimation Uncertainty and Critical Accounting Judgments	4. Key Sources of Estimation Uncertainty and Critical Accounting Judgments The preparation of the Company’s condensed interim consolidated financial statements requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities and contingent liabilities at the date of the consolidated financial statements and reported amounts of revenues and expenses during the reporting period. Estimates and assumptions are continuously evaluated and are based on management’s experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. However, actual outcomes can differ from these estimates. Information about significant areas of estimation uncertainty and judgments made by management in preparing the condensed interim consolidated financial statements are unchanged from those disclosed in Note 4 to the audited consolidated financial statements for the year ended December 31, 2022.

Financial Instruments	5. Financial Instruments 5.1. Capital Risk Management The Company manages its capital to ensure that it will be able to continue as a going concern and satisfy its outstanding funding commitments while maintaining a high degree of financial flexibility to consummate new streaming investments. The capital structure of the Company consists of debt (Note 17) and equity attributable to common shareholders, comprising of issued capital (Note 18), accumulated reserves (Note 19) and retained earnings. The Company is not subject to any externally imposed capital requirements with the exception of complying with the minimum tangible net worth covenant under the credit agreement governing bank debt (Note 17). The Company is in compliance with the debt covenants at June 30, 2023, as described in Note 17.1. 5.2. Categories of Financial Assets and Liabilities The refundable deposit on the 777 PMPA, which requires a single principal payment at maturity, is carried at amortized cost. Trade receivables from sales of cobalt and other receivables are non-interest (in thousands) Note June 30 2023 December 31 2022 Financial assets Financial assets mandatorily measured at FVTNE 1 Cash and cash equivalents 2 2 $ 828,837 $ 696,089 Trade receivables from provisional concentrate sales, net of fair value adjustment 6,11 1,105 2,516 Long-term investments - warrants held 458 560 Investments in equity instruments designated at FVTOCI 1 Long-term investments - common shares held 1 5 255,076 255,535 Financial assets measured at amortized cost Trade receivables from sales of cobalt 11 4,945 6,642 Refundable deposit - 777 PMPA 2 5 8,393 8,073 Other accounts receivable 921 1,029 Total financial assets $ 1,099,735 $ 970,444 Financial liabilities Financial liabilities at amortized cost Accounts payable and accrued liabilities $ 9,578 $ 12,570 Pension liability 3,949 3,524 Total financial liabilities $ 13,527 $ 16,094 1) FVTNE refers to Fair Value Through Net Earnings, FVTOCI refers to Fair Value Through Other Comprehensive Income 5.3. Credit Risk Credit risk is the risk that the counterparty to a financial instrument will cause a financial loss for the Company by failing to discharge its obligations. To mitigate exposure to credit risk on financial assets, the Company has established policies to limit the concentration of credit risk, to ensure counterparties demonstrate minimum acceptable credit worthiness and to ensure liquidity of available funds. The Company closely monitors its financial assets and does not have any significant concentration of credit risk. The Company invests surplus cash in short-term, high credit quality, money market instruments. Additionally, the outstanding accounts receivable from the sales of cobalt are supported by a $7.5 million letter of credit. Finally, counterparties used to sell precious metals are all large, international organizations with strong credit ratings and the balance of trade receivables on these sales in the ordinary course of business is not significant. Therefore, credit risk associated with trade receivables at June 30, 2023 is considered to be negligible. The Company’s maximum exposure to credit risk related to its financial assets is as follows: (in thousands) Note June 30 2023 December 31 2022 Cash and cash equivalents 2 2 $ 828,837 $ 696,089 Trade receivables from provisional concentrate sales, net of fair value adjustment 11 1,105 2,516 Trade receivables from sales of cobalt 11 4,945 6,642 Refundable Deposit - 777 PMPA 2 5 8,393 8,073 Other accounts receivables 11 921 1,029 Maximum exposure to credit risk related to financial assets $ 844,201 $ 714,349 5.4. Liquidity Risk The Company has in place a rigorous planning and budgeting process to help determine the funds required to support the Company’s normal operating requirements on an ongoing basis and its expansionary plans. The Company ensures that there are sufficient committed loan facilities to meet its short-term business requirements, taking into account its anticipated cash flows from operations and its holdings of cash and cash equivalents. As at June 30, 2023, the Company had cash and cash equivalents of $829 million (December 31, 2022 - $696 million) and working capital of $831 million (December 31, 2022 - $689 million). The Company holds equity investments of several companies (Note 1 5 The following table summarizes the timing associated with the Company’s remaining contractual payments relating to its financial liabilities. The table reflects the undiscounted cash flows of financial liabilities based on the earliest date on which the Company can be required to pay (assuming that the Company is in compliance with all of its obligations). The table includes both interest and principal cash flows, where applicable.

Currency Risk The Company undertakes certain transactions denominated in Canadian dollars, including certain operating expenses and the acquisition of strategic long-term investments. As a result, the Company is exposed to fluctuations in the value of the Canadian dollar relative to the United States dollar. The carrying amounts of the Company’s Canadian dollar denominated monetary assets and monetary liabilities at the end of the reporting period are as follows: (in thousands) June 30 2023 December 31 2022 Monetary assets Cash and cash equivalents $ 4,539 $ 311 Accounts receivable 128 739 Long-term investments - common shares held 74,927 60,443 Long-term investments - warrants held 459 560 Other long-term assets 3,384 3,308 Total Canadian dollar denominated monetary assets $ 83,437 $ 65,361 Monetary liabilities Accounts payable and accrued liabilities $ 6,469 $ 8,180 Performance share units 10,579 16,971 Lease liability 6,037 1,315 Pension liability 3,949 3,524 Total Canadian dollar denominated monetary liabilities $ 27,034 $ 29,990 The following tables detail the Company’s sensitivity to a 10% increase or decrease in the Canadian dollar relative to the United States dollar, representing the sensitivity used when reporting foreign currency risk internally to key management personnel and represents management’s assessment of the reasonably possible change in exchange rates. As at June 30, 2023 Change in Canadian Dollar (in thousands) 10% Increase 10% Decrease Increase (decrease) in net earnings $ (1,852) $ 1,852 Increase (decrease) in other comprehensive income 7,493 (7,493) Increase (decrease) in total comprehensive income $ 5,641 $ (5,641) As at December 31, 2022 Change in Canadian Dollar (in thousands) 10% Increase 10% Decrease Increase (decrease) in net earnings $ (2,507) $ 2,507 Increase (decrease) in other comprehensive income 6,044 (6,044) Increase (decrease) in total comprehensive income $ 3,537 $ (3,537) 5.6. Interest Rate Risk The Company is exposed to interest rate risk on its outstanding borrowings and short-term investments. Presently, the Company has no outstanding borrowings, and historically all borrowings have been at floating interest rates. The Company monitors its exposure to interest rates and has not entered into any derivative contracts to manage this risk. During the three and six months ended June 30, 2023 and 2022, the weighted average effective interest rate paid by the Company on its outstanding borrowings was Nil. During the three and six months ended June 30, 2023 and 2022, a fluctuation in interest rates of 100 basis points (1 percent) would not have impacted the amount of interest expensed by the Company. 5.7. Other Price Risk The Company is exposed to equity price risk as a result of holding long-term investments in common shares of various companies. The Company does not actively trade these investments. If equity prices had been 10% higher or lower at the respective balance sheet date, other comprehensive income for the three and six months ended June 30, 2023 and 2022 would have increased/decreased by approximately $26 million and $6 million respectively, as a result of changes in the fair value of common shares held. 5.8. Fair Value Estimation The Company classifies its fair value measurements within a fair value hierarchy, which reflects the significance of the inputs used in making the measurements as defined in IFRS 13 – Fair Value Measurements (“IFRS 13”). Level 1 - Unadjusted quoted prices at the measurement date for identical assets or liabilities in active markets. Level 2 - Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 - Unobservable inputs which are supported by little or no market activity. The following table sets forth the Company’s financial assets and liabilities measured at fair value by level within the fair value hierarchy. As required by IFRS 13, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

Trade accounts receivables, other accounts receivables and accounts payables and accrued liabilities are non-interest When balances are outstanding, the Company’s bank debt (Note 1 7 5.8.1. Valuation Techniques for Level 1 Assets Cash and Cash Equivalents The Company’s cash and cash equivalents are valued using quoted market prices in active markets and, as such, are classified within Level 1 of the fair value hierarchy. Long-Term Investments in Common Shares Held The Company’s long-term investments in common shares held are valued using quoted market prices in active markets and, as such, are classified within Level 1 of the fair value hierarchy. The fair value of the long-term investments in common shares held is calculated as the quoted market price of the common share multiplied by the quantity of shares held by the Company. 5.8.2. Valuation Techniques for Level 2 Assets Accounts Receivable Arising from Sales of Metal Concentrates The Company’s trade receivables and accrued liabilities from provisional concentrate sales are valued based on forward prices of gold and silver to the expected date of final settlement (Note 6). As such, these receivables and/or liabilities are classified within Level 2 of the fair value hierarchy. Long-Term Investments in Warrants Held The fair value of the Company’s long-term investments in warrants held that are not traded in an active market are determined using a Black-Scholes model based on assumptions including risk free interest rate, expected dividend yield, expected volatility and expected warrant life which are supported by observable current market conditions and as such are classified within Level 2 of the fair value hierarchy. The use of reasonably possible alternative assumptions would not significantly affect the Company’s results.

Revenue from precious metal credit sales is recognized at the time of the sale of such credits, which is also the date that control of the precious metal is transferred to the customer. The Company will occasionally enter into forward contracts in relation to precious metal deliveries that it is highly confident will occur within a given quarter. The sales price is fixed at the delivery date based on either the terms of these short-term forward sales contracts or the spot price of precious metal. Concentrate Sales Under certain PMPAs, gold and/or silver is acquired from the mine operator in concentrate form, which is then sold under the terms of the concentrate sales contracts to third-party smelters or traders. Where the Company acquires precious metal in concentrate form, final precious metal prices are set on a specified future quotational period (the “Quotational Period”) pursuant to the concentrate sales contracts with third-party smelters, typically one to three months after the shipment date, based on market prices for precious metal. The contracts, in general, provide for a provisional payment based upon provisional assays and quoted gold and silver prices. Final settlement is based upon the average applicable price for the Quotational Period applied to the actual number of precious metal ounces recovered calculated using confirmed smelter weights and settlement assays. Revenues and the associated cost of sales are recorded on a gross basis under these contracts at the time title passes to the customer, which is also the date that control of the precious metal is transferred to the customer. The Company has concluded that the adjustments relating to the final assay results for the quantity of concentrate sold are not significant and do not constrain the recognition of revenue. Cobalt Sales Cobalt is sold to a third-party sales agent who generally on-sells e

Restricted Share Units (“RSUs”) The Company has established an RSU plan whereby RSUs will be issued to eligible employees or directors as determined by the Company’s Board of Directors or the Company’s Compensation Committee. RSUs give the holder the right to receive a specified number of common shares at the specified vesting date. RSUs generally vest over a period of two to three years. Compensation expense related to RSUs is recognized over the vesting period based upon the fair value of the Company’s common shares on the grant date and the awards that are expected to vest. The fair value is calculated with reference to the closing price of the Company’s common shares on the TSX on the business day prior to the date of grant. RSU holders receive a cash payment based on the dividends paid on the Company’s common shares in the event that the holder of a vested RSU has elected to defer the release of the RSU to a future date. This cash payment is reflected as a component of net earnings under the classification Share Based Compensation.

To the extent that the value of the long-term investment subsequently declines, the deferred income tax liability is reduced. However, where the fair value of the long-term investment decreases below the tax cost, the Company does not recognize a deferred income tax asset on the unrealized capital loss unless it is probable that the Company will generate future capital gains that will offset the loss.

PSUs issued under the PSU plan entitle the holder to a cash payment at the end of a three year performance period equal to the number of PSUs granted, multiplied by a performance factor and multiplied by the fair market value of a Wheaton common share on the expiry of the performance period. The performance factor can range from 0% to 200% and is determined by comparing the Company’s total shareholder return to those achieved by various peer companies, the Philadelphia Gold and Silver Index and the price of gold and silver. Compensation expense for the PSUs is recorded on a straight-line basis over the three year vesting period.

On July 5, 2022, Rio2 announced that the Regional Evaluation Commission has voted to not approve the EIA. On September 7, 2022, Rio2 announced that on review of the Environmental Qualification Resolution (“RCA”), Rio2 identified numerous discrepancies with factual and procedural matters in the RCA and Rio2 has filed an administrative appeal on August 31, 2022.

Kutcho Under the terms of the Kutcho Early Deposit Agreement, the Company is committed to pay Kutcho additional upfront cash payments of $58 million, which will be advanced on an installment basis to partially fund construction of the mine once certain conditions have been satisfied. Taxes – Canada Revenue Agency – 2013 to 2016 Taxation Years - Domestic Reassessments The Company received Notices of Reassessment in 2018, 2019, and 2022 for the 2013 to 2016 taxation years in which the Canada Revenue Agency (“CRA”) is seeking to change the timing of the deduction of upfront payments with respect to the Company’s PMPAs relating to Canadian mining assets, so that the cost of precious metal acquired under these Canadian PMPAs is equal to the cash cost paid on delivery plus an amortized amount of the upfront payment determined on a units-of-production In total, the Company expects the Domestic Reassessments to have assessed tax, interest and other penalties of approximately $2 million. Management believes the Company’s position, as reflected in its filed Canadian income tax returns and consistent with the terms of the PMPAs, that the cost of the precious metal acquired under the Canadian PMPAs is equal to the market value while a deposit is outstanding, and the cash cost thereafter, is correct. The Company has filed Notices of Objection and paid 50% of the disputed amounts in order to challenge the Domestic Reassessments. Tax Contingencies Due to the size, complexity and nature of the Company’s operations, various legal and tax matters are outstanding from time to time, including audits and disputes. Under the terms of the settlement with the CRA of the transfer pricing dispute relating to the 2005 to 2010 taxation years (the “CRA Settlement”), income earned outside of Canada by the Company’s foreign subsidiaries will not be subject to tax in Canada under transfer pricing rules. The CRA Settlement principles apply to all taxation years after 2010 subject to there being no material change in facts or change in law or jurisprudence. The CRA is not restricted under the terms of the CRA Settlement from issuing reassessments on some basis other than transfer pricing which could result in some or all of the income of the Company’s foreign subsidiaries being subject to tax in Canada. It is not known or determinable by the Company when the currently ongoing audits by CRA of international and domestic transactions will be completed, or whether reassessments will be issued, or the basis, quantum or timing of any such potential reassessments, and it is therefore not practicable for the Company to estimate the financial effect, if any, of those ongoing audits. From time to time there may also be proposed legislative changes to law or outstanding legal actions that may have an impact on the current or prior periods, the outcome, applicability and impact of which is also not known or determinable by the Company. General By their nature, contingencies will only be resolved when one or more future events occur or fail to occur. The assessment of contingencies inherently involves the exercise of significant judgment and estimates of the outcome of future events. If the Company is unable to resolve any of these matters favorably, there may be a material adverse impact on the Company’s financial performance, cash flows or results of operations. In the event that the Company’s estimate of the future resolution of any of the foregoing matters changes, the Company will recognize the effects of the change in its consolidated financial statements in the appropriate period relative to when such change occurs.

Subsequent Events	29. Subsequent Events Declaration of Dividend Under the Company’s dividend policy, the quarterly dividend per common share is targeted to equal approximately 30% of the average cash flow generated by operating activities in the previous four quarters divided by the Company’s then outstanding common shares, all rounded to the nearest cent. To minimize volatility in quarterly dividends, the Company has set a minimum quarterly dividend for the duration of 2023 equal to the dividend per common share declared in the prior quarter, which was $0.15 per share. The declaration, timing, amount and payment of future dividends remain at the discretion of the Board of Directors. On August 10, 2023, the Board of Directors declared a dividend in the amount of $0.15 per common share, with this dividend being payable to shareholders of record on August 25, 2023 and is expected to be distributed on or about September 7, 2023. The Company has implemented a dividend reinvestment plan (“DRIP”) whereby shareholders can elect to have dividends reinvested directly into additional Wheaton common shares based on the Average Market Price, as defined in the DRIP.

New Accounting Standards Effective in 2023	3.1. New Accounting Standards Effective in 2023 Amendment to IAS 12 - Deferred Tax related to Assets and Liabilities arising from a Single Transaction The amendments to IAS 12 clarify that the initial recognition exemption does not apply to transactions in which equal amounts of deductible and taxable temporary differences arise on initial recognition. The amendments are effective for annual reporting periods beginning on or after January 1, 2023. Early application of the amendments is permitted. The amendments apply to transactions that occur on or after the beginning of the earliest comparative period presented. In addition, at the beginning of the earliest comparative period the following would be recognized: · a deferred tax asset to the extent that it is probable that taxable profit will be available against which the deductible temporary difference can be utilized and a deferred tax liability for all deductible and taxable temporary differences associated with right-of-use · the cumulative effect of initially applying the amendments as an adjustment to the opening balance of retained earnings (or other component of equity, as appropriate) at that date. The implementation of this amendment did not have a material impact on the Company. Amendments to IAS 1 and IFRS Practice Statement 2 – Disclosure of Accounting policies The amendments require that an entity discloses its material accounting policy information, instead of its significant accounting policies. Further amendments explain how an entity can identify a material accounting policy. Examples of when an accounting policy is likely to be material are added. To support the amendment, the IASB has also developed guidance and examples to explain and demonstrate the application of the ‘four-step materiality process’ described in IFRS Practice Statement 2. The amendments are effective for annual reporting periods beginning on or after January 1, 2023. This amendment did not have a significant impact to the Company’s condensed interim consolidated financial statements.
Future Changes in Accounting Policies	3.2. Future Changes to Accounting Policies The IASB has issued the following new or amended standards: Amendment to IAS 1- The amendments to IAS 1, clarify the presentation of liabilities.

The mandatory temporary exemption is effective immediately and the disclosure requirements are effective for annual periods beginning January 1, 2023. The Company has applied this mandatory exception in the current period. Refer to Note 23 for further information on Global Minimum Tax.

[1]As at June 30, 2023, the Company had recognized the tax effect on $2 million of non-capital losses against deferred tax liabilities.[2]Other includes capital assets, cobalt inventory, charitable donation carryforward, and PSU and pension liabilities.[3]Debt and share financing fees are deducted over a five-year period for Canadian income tax purposes. For accounting purposes, debt financing fees are deducted over the term of the credit facility and share financing fees are charged directly to issued capital.[4]The Company’s position, as reflected in its filed Canadian income tax returns and consistent with the terms of the PMPAs, is that the cost of the precious metal acquired under the Canadian PMPAs is equal to the market value while a deposit is outstanding (where applicable to an agreement), and the cash cost thereafter. For accounting purposes, the cost of the mineral stream interests is depleted on a unit-of-production basis as described in Note 13.

[1]Under the terms of the San Dimas PMPA, the Company is entitled to an amount equal to 25% of the payable gold production plus an additional amount of gold equal to 25% of the payable silver production converted to gold at a fixed gold to silver exchange ratio of 70:1 from the San Dimas mine. If the average gold to silver price ratio decreases to less than 50:1 or increases to more than 90:1 for a period of 6 months or more, then the “70” shall be revised to “50” or “90”, as the case may be, until such time as the average gold to silver price ratio is between 50:1 to 90:1 for a period of 6 months or more in which event the “70” shall be reinstated. Currently, the fixed gold to silver exchange ratio is 70:1.
