SIGNIFICANT ACCOUNTING POLICIES

SIGNIFICANT ACCOUNTING POLICIES	6 Months Ended

Significant Accounting Policies [Abstract]
Significant Accounting Policies	SIGNIFICANT ACCOUNTING POLICIES A) Statement of Compliance These condensed interim consolidated financial statements have been prepared in accordance with International Accounting Standard 34 Interim Financial Reporting (“IAS 34”) as issued by the International Accounting Standards Board (“IASB”). These interim financial statements should be read in conjunction with Barrick’s most recently issued Annual Report which includes information necessary or useful to understanding the Company’s business and financial statement presentation. In particular, the Company’s significant accounting policies were presented in Note 2 of the Annual Consolidated Financial Statements for the year ended December 31, 2017 ("2017 Annual Financial Statements"), and have been consistently applied in the preparation of these interim financial statements, except as otherwise noted in Note 2(b). These condensed interim consolidated financial statements were authorized for issuance by the Board of Directors on July 25, 2018. B) New Accounting Standards Effective in 2018 Impact of Adoption of IFRS 15 Revenue from Contracts with Customers We have adopted the requirements of IFRS 15 Revenue from Contracts with Customers ("IFRS 15") as of January 1, 2018. IFRS 15 covers principles that an entity shall apply to report useful information to users of financial statements about the nature, amount, timing, and uncertainty of revenue and cash flows arising from a contract with a customer. We elected to apply IFRS 15 using a modified retroactive approach by recognizing the cumulative effect of initially adopting IFRS 15 as an adjustment to the opening balance sheet through equity at January 1, 2018. Therefore, the comparative information has not been restated and continues to be reported under IAS 18 Revenue ("IAS 18"). The details of accounting policy changes and the quantitative impact of these changes are described below. Gold Bullion Sales IFRS 15 requires that revenue from contracts with customers be recognized upon the transfer of control over goods or services to the customer. The recognition of revenue upon transfer of control to the customer is consistent with our revenue recognition policy as set out in Note 2(f) of the 2017 Annual Financial Statements, as the condition is generally satisfied when title transfers to the customer. As such, upon adoption, this requirement under IFRS 15 resulted in no impact to our financial statements as the timing of revenue recognition on our gold bullion sales is unchanged. Concentrate Sales We assessed all of our existing concentrate sales agreements and determined that there is no change in the timing of revenue recognition, as control transfers to the smelting companies at the time of shipment, consistent with our current accounting policy as set out in Note 2(f) of the 2017 Annual Financial Statements. Although IFRS 15 identifies the shipping component associated with concentrate sales as a separate performance obligation, requiring a portion of the revenue to be deferred and only recognized once the shipment has reached the destination port, we have determined that the deferred revenue would be insignificant and thus, have not accounted for the shipping component as a separate performance obligation. IFRS 15 does not consider provisional price adjustments associated with concentrate sales to be revenue from contracts with customers as they arise from changes in market gold and copper prices between the shipment date and settlement date. As such, we have separately presented provisional price adjustments in Note 6 of these condensed interim consolidated financial statements in line with the requirements of IFRS 15. Streaming Agreements IFRS 15 requires that for contracts containing variable consideration, the transaction price be continually updated and re-allocated to the transferred goods and services. As a result, we have updated our accounting policy for revenue earned on streaming agreements such that we will treat the deferred revenue component as variable, requiring an adjustment to the transaction price per unit each time there is a change in the underlying production profile of a mine (typically in the fourth quarter of each year). The change in the transaction price per unit results in a retroactive adjustment to revenue in the period in which the change is made, reflecting the new production profile expected to be delivered under the streaming agreement. A corresponding retroactive adjustment is made to accretion expense, reflecting the impact of the change in the deferred revenue balance. The impact of the initial adoption of this change in accounting policy was an adjustment to reduce the opening deficit on January 1, 2018 of $64 million with a corresponding adjustment to reduce the deferred revenue balance. There was no impact to net income for the period. If in the second quarter and first half of 2018 we had continued to recognize revenue on streaming agreements in accordance with IAS 18, the amounts recognized for revenue, deferred revenue and interest expense would have been insignificantly different from those recognized in accordance with IFRS 15. C) New Accounting Standards Issued But Not Yet Effective IFRS 16 Leases In January 2016, the IASB issued IFRS 16 Leases, which requires lessees to recognize assets and liabilities for most leases. Application of the standard is mandatory for annual reporting periods beginning on or after January 1, 2019, with earlier application permitted, provided the new revenue standard, IFRS 15 Revenue from Contracts with Customers, has been applied or is applied at the same date as IFRS 16. We are not early adopting IFRS 16. We expect that IFRS 16 will result in an increase in assets and liabilities as fewer leases will be expensed as payments are made. We expect an increase in depreciation and accretion expenses, a decrease in operating expense and an increase in cash flow from operating activities as these lease payments will be recorded as financing outflows in our cash flow statement. We have developed a full implementation plan to determine the impact on our financial statements and internal controls. In the fourth quarter of 2017, we formed an IFRS 16 working group and began the process of compiling all of our existing operating leases and service contracts. In the first quarter of 2018, we began reviewing the relevant agreements to identify which of the operating leases and service contracts are in scope for IFRS 16. In the second quarter of 2018, we have largely completed our review of existing service contracts for embedded leases and have identified all operating leases. In the third quarter of 2018, we will complete our embedded lease review and will begin valuing our population of leases. We will provide further updates on the progression of our project plan in our subsequent interim financial statements.

A) Provision for Environmental Rehabilitation (“PER”) Provisions are updated each reporting period for changes to expected cash flows and for the effect of changes in the discount rate and foreign exchange rate, and the change in estimate is added or deducted from the related asset and depreciated over the expected economic life of the operation to which it relates. We recorded a net increase of $24 million ( 2017 : $62 million net decrease ) to the PER at our minesites for the three months ended June 30, 2018 and a net decrease of $82 million ( 2017 : $7 million net decrease ) for the six months ended June 30, 2018 . Adjustments to the estimated amount and timing of future closure and rehabilitation cash flows are a normal occurrence in light of the significant judgments and estimates involved. Rehabilitation provisions are adjusted as a result of changes in estimates and assumptions and are accounted for prospectively. In the fourth quarter of each year, our life of mine plans are updated and that typically results in an update to the rehabilitation provision. Under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (“CERCLA”) and its state law equivalents, present or past owners of a property may be held jointly and severally liable for cleanup costs or forced to undertake remedial actions in response to unpermitted releases of hazardous substances at such property, in addition to, among other potential consequences, potential liability to governmental entities for the cost of damages to natural resources, which may be substantial. These subject properties are referred to as “superfund” sites. There is a chance that our current or legacy operations in the U.S. could be designated as a superfund site in the future, exposing Barrick to potential liability under CERCLA. The U.S. Environmental Protection Agency recently announced it is considering listing on the CERCLA National Priorities List a 322 square mile site in the San Mateo basin in New Mexico (“San Mateo Site”) due to alleged surface and ground water contamination from past uranium mining. The San Mateo Site includes legacy operations of Homestake Mining Company of California. B) Pascua-Lama The Pascua-Lama project received $469 million as at June 30, 2018 ( December 31, 2017 : $484 million) in value added tax (“VAT”) refunds in Chile relating to the development of the Chilean side of the project. Under the current arrangement this amount plus interest of $335 million ( December 31, 2017 : $313 million) must be repaid if the project does not evidence exports for an amount of $3,538 million within a term that expires on December 31, 2026. The terms of the current VAT arrangement in Chile are applicable to either an open pit or an underground mine design. In addition, we have recorded $145 million in VAT recoverable in Argentina as at June 30, 2018 ( December 31, 2017 : $221 million) relating to the development of the Argentine side of the project. These amounts may not be recoverable if the project does not enter into production and are subject to foreign currency risk as the amounts are recoverable in Argentine pesos. C) Contingencies Contingencies can be either possible assets or possible liabilities arising from past events which, by their nature, will be resolved only when one or more future events, not wholly within our control, occur or fail to occur. The assessment of such contingencies inherently involves the exercise of significant judgment and estimates of the outcome of future events. Refer to note 17 for further details on contingencies. D) Streaming Transactions The deferred revenue component of our streaming agreements is considered variable and is subject to retroactive adjustment when there is a change in the timing of the delivery of ounces or in the underlying production profile of the relevant mine. The impact of such a change in the timing or quantity of ounces to be delivered under a streaming agreement will result in retroactive adjustments to both the deferred revenue recognized and the accretion recorded prior to the date of the change. There were no retroactive adjustments recorded in the first half of 2018, with the exception of the adjustment recorded to reflect the initial adoption of IFRS 15 as outlined in note 2(b). Refer to note 2(b) for further details on our accounting for Streaming Transactions.

Business Combinations and Discontinued Operations [Abstract]
DIVESTITURES	DIVESTITURES A) Investment in Midas Gold On May 9, 2018, we announced the acquisition of 46.55 million common shares, representing approximately 19.9 percent of issued and outstanding common shares of Midas Gold Corporation in a non-brokered private placement for total consideration of $38 million. Upon acquisition of the shares, we have accounted for our interest as other investments with future changes in fair value recorded in other comprehensive income. B) Sale of 50% of Veladero On April 6, 2017, we announced a strategic cooperation agreement with Shandong Gold Group Co., Ltd. (“Shandong”) where Shandong agreed to acquire 50 percent of Barrick’s Veladero mine in Argentina for $ 960 million. The transaction closed on June 30, 2017 and in the second quarter of 2017 we recognized a total gain of $ 689 million, partially on the sale of 50 percent to Shandong and partially upon remeasurement of our remaining interest in Veladero. C) Sale of 25% of the Cerro Casale Project On March 28, 2017, we announced an agreement with Goldcorp Inc. (“Goldcorp”) to form a new partnership at the Cerro Casale Project in Chile. The transaction closed on June 9, 2017. Under the terms of the agreement, Goldcorp agreed to purchase a 25 percent interest in the Cerro Casale Project from Barrick. This transaction, coupled with the concurrent purchase by Goldcorp of Kinross Gold Corporation’s (“Kinross”) 25 percent interest in the Cerro Casale Project, resulted in Barrick and Goldcorp each holding a 50 percent interest in the newly formed Cerro Casale joint operation. This ownership change coupled with the specific terms of the agreement caused a change in control of the Cerro Casale Project and we remeasured our retained interest in the joint operation at fair value at the date control was lost. The total consideration received by Barrick and Kinross implied a fair value of $1.2 billion for 100 percent of the Cerro Casale Project, which resulted in a reversal of previously recorded impairment charges of $1.12 billion in the first quarter of 2017. We recognized a gain of $193 million due to the deconsolidation of the non-controlling interest in the Cerro Casale Project in the second quarter of 2017. This joint operation is now referred to as Norte Abierto and includes the Cerro Casale, Caspiche and Luciano deposits.

Operating Segments [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION Barrick’s business is organized into eleven individual minesites, one grouping of two minesites, one publicly traded company and one project. Barrick’s Chief Operating Decision Maker (“CODM”), the President, reviews the operating results, assesses performance and makes capital allocation decisions at the minesite, grouping, Company and/or project level. Therefore, each individual minesite, with the exception of Barrick Nevada, Acacia and the Pascua-Lama project are operating segments for financial reporting purposes. Our presentation of our reportable operating segments is four individual gold mines (Pueblo Viejo, Lagunas Norte, Veladero and Turquoise Ridge), Barrick Nevada, Acacia and our Pascua-Lama project. The remaining operating segments, our remaining gold and copper mines, have been grouped into an “other” category and will not be reported on individually. Segment performance is evaluated based on a number of measures including operating income before tax, production levels and unit production costs. Certain costs are managed on a consolidated basis and are therefore not reflected in segment income.

The underlying effective tax rate for ordinary income for the six months ended June 30, 2018 was 44% after adjusting for the impact of the Dominican Republic tax audit; the net impact of foreign currency translation losses on deferred tax balances; the impact of impairment (reversals) charges; the impact of asset sales and non-hedge derivatives; the impact of non-deductible foreign exchange losses, and the impact of other expense adjustments. The unadjusted tax rate for income for the six months ended June 30, 2018 , was 73% of the income before income taxes. Currency Translation Deferred tax balances are subject to remeasurement for changes in currency exchange rates each period. The most significant balances are Argentine net deferred tax liabilities. In the six months ended June 30, 2018 and 2017 , tax expense of $ 19 million and $3 million, respectively, primarily arose from translation losses on tax balances in Argentina, due to the weakening of the Argentine peso against the U.S. dollar. These translation losses are included within deferred income tax expense. Dominican Republic Tax Audit In the first quarter of 2018, current tax expense of $ 5 million and deferred tax expense of $ 37 million were recorded, resulting from a tax audit of Pueblo Viejo in the Dominican Republic. The deferred tax expense relates to additional tax deductions included in the audit that reduced deferred tax assets but did not reduce tax expense due to the application of annual minimum tax (AMT) in certain taxation years.

Impairment of Goodwill and Other Assets [Abstract]
Impairment of Goodwill and Other Assets	IMPAIRMENT OF GOODWILL AND OTHER ASSETS In accordance with our accounting policy, goodwill is tested for impairment in the fourth quarter and also when there is an indicator of impairment. Non-current assets are tested for impairment or impairment reversals when events or changes in circumstances suggest that the carrying amount may not be recoverable. Refer to note 21 of the 2017 Annual Financial Statements for further information. For the six months ended June 30, 2018 , we recorded impairments of $61 million ( 2017 : $1,130 million impairment reversals) for non-current assets, as summarized in the following table: Summary of impairments (reversals) For the three months ended June 30 For the six months ended June 30 2018 2017 2018 2017 Equity Method Investments $30 $— $30 $— Acacia 24 — 24 — Barrick Nevada 11 — 14 — Cerro Casale — — — (1,120 ) Pascua-Lama (6 ) (9 ) (7 ) (15 ) Other — 4 — 5 Total $59 ($5 ) $61 ($1,130 ) Indicators of impairment Second Quarter 2018 Acacia In the second quarter of 2018, potential indicators of impairment were identified in relation to Acacia, specifically the ongoing uncertainty surrounding a potential resolution between Barrick and the Government of Tanzania ('GoT') as well as the sustained decline in Acacia's market capitalization below its carrying value over the first half of 2018. As a result, an impairment assessment was undertaken in the second quarter, with no impairment loss identified. The assessment assumed the resumption of concentrate sales and of operations at Bulyanhulu will occur in the second quarter of 2019 and in late 2019, respectively. The assessment also reflected the targeted outcome for a negotiated resolution in line with the proposed framework as reflected in the most recent life of mine ('LOM') plan. The key assumptions and estimates used in determining the fair value less cost to dispose ("FVLCD') are short- and long-term gold prices of $1,200 and a discount rate of 11% , consistent with the rate used for the impairment assessment completed at December 31, 2017 in the calculation of FVLCD. FVLCD is most sensitive to changes in these key assumptions and to the timing of resolution of the export ban, therefore a sensitivity analysis was performed based on a decrease in the long-term gold price of $100 per ounce, and increase in the discount rate of 1%, and a further six month delay in the resolution of the export ban. A $ 100 per ounce decrease in long-term gold price would result in the recognition of a non-current asset impairment at Bulyanhulu of $98 million, net of tax. A 1% increase in the discount rate and a further delay of six months in the resolution of the export ban would not result in the recognition of an impairment. However, should a negotiated resolution not eventuate, the recoverable value of Bulyanhulu may be further impacted, resulting in a review at such time. Subsequent to the second quarter close, OreCorp, which is Acacia's joint venture partner in the Nyanzaga project in Tanzania, executed its option under the earn-in agreement to increase its ownership in the project to 51% through a $3 million payment to Acacia. Furthermore, Acacia signed a conditional agreement to sell its remaining 49% interest in the project to OreCorp for $7 million and a net smelter royalty capped at $15 million based on future production. As a result of the agreement, and Acacia's commitment to a sale, Acacia expects to recover the value of the asset through sale and not value in use and as such has valued the asset at fair value less costs to sell of $ 10 million, resulting in the recognition of an impairment loss of US $24 million in the second quarter of 2018. Kabanga In January 2018, new mining regulations relating to mineral rights were issued in Tanzania. These regulations canceled all retention licenses and declared that they no longer have legal effect and any previous holder, along with any third party, of a retention license would need to apply for a new prospecting or mining license for that area. Our 50% interest in the Kabanga project (a joint venture between Barrick and Glencore) was affected by these changes. While we have now submitted our application for a prospecting license, the operating environment for mining projects in Tanzania remains challenging and we have determined that our carrying amount for the project is not recoverable under the current circumstances. As such, we considered this an indicator of impairment, resulting in the recognition of a $30 million impairment, which is equal to the full carrying value of our equity-method investment in the Kabanga JV, in the second quarter of 2018. First Quarter 2017 Cerro Casale As noted in note 4(c), on March 28, 2017, we announced the sale of a 25% interest in the Cerro Casale Project in Chile, which would result in Barrick retaining a 50% interest in the Project and this was deemed to be an indicator of impairment reversal in the first quarter of 2017. As such, in first quarter 2017, we recognized a partial reversal of the non-current asset impairment recorded in the fourth quarter of 2014 in the amount of $ 1.12 billion. The recoverable amount, based on the fair value less cost to dispose as implied by the transaction price, was $ 1.2 billion.

The description set out below should be read in conjunction with Note 36 “Contingencies” to the 2017 Annual Financial Statements. Litigation and Claims Update US Shareholder Class Action Briefing on the motion to dismiss was completed on April 18, 2018. A decision of the Court is pending. Veladero - September 2015 Release of Cyanide-Bearing Process Solution and Glacier Legislation Criminal Matters On March 5, 2018, the Court of Appeals confirmed the indictment against the four former federal officials in relation to the enforcement of the national glacier legislation. In a separate investigation, on April 11, 2018, the federal judge indicted two additional former federal officials and confirmed a second charge against one of the former federal officials originally indicted on November 27, 2017, alleging breach of duty in connection with their actions and omissions related to the failure to maintain adequate environmental controls. On July 10, 2018, the Court of Appeals confirmed this later indictment as well. In total, six former federal officials have now been indicted under these proceedings (one of whom has been indicted on two separate charges) and will face trial. On June 29, 2018, the federal judge ordered additional environmental studies to be conducted in communities downstream from the Veladero mine as part of the investigation into the alleged failure of three former federal government officials to maintain adequate environmental controls. The Province of San Juan has challenged this order on jurisdictional grounds. Veladero - September 2016 Release of Crushed Ore Saturated with Process Solution Temporary Suspension of Operations and Regulatory Infringement Proceeding On March 28, 2018, MAG was notified that the San Juan Provincial mining authority had rejected the request for reconsideration.

Significant Accounting Policies [Abstract]
Statement of Compliance	A) Statement of Compliance These condensed interim consolidated financial statements have been prepared in accordance with International Accounting Standard 34 Interim Financial Reporting (“IAS 34”) as issued by the International Accounting Standards Board (“IASB”). These interim financial statements should be read in conjunction with Barrick’s most recently issued Annual Report which includes information necessary or useful to understanding the Company’s business and financial statement presentation. In particular, the Company’s significant accounting policies were presented in Note 2 of the Annual Consolidated Financial Statements for the year ended December 31, 2017 ("2017 Annual Financial Statements"), and have been consistently applied in the preparation of these interim financial statements, except as otherwise noted in Note 2(b). These condensed interim consolidated financial statements were authorized for issuance by the Board of Directors on July 25, 2018.
New Accounting Standards Effective in 2018	B) New Accounting Standards Effective in 2018 Impact of Adoption of IFRS 15 Revenue from Contracts with Customers We have adopted the requirements of IFRS 15 Revenue from Contracts with Customers ("IFRS 15") as of January 1, 2018. IFRS 15 covers principles that an entity shall apply to report useful information to users of financial statements about the nature, amount, timing, and uncertainty of revenue and cash flows arising from a contract with a customer. We elected to apply IFRS 15 using a modified retroactive approach by recognizing the cumulative effect of initially adopting IFRS 15 as an adjustment to the opening balance sheet through equity at January 1, 2018. Therefore, the comparative information has not been restated and continues to be reported under IAS 18 Revenue ("IAS 18"). The details of accounting policy changes and the quantitative impact of these changes are described below. Gold Bullion Sales IFRS 15 requires that revenue from contracts with customers be recognized upon the transfer of control over goods or services to the customer. The recognition of revenue upon transfer of control to the customer is consistent with our revenue recognition policy as set out in Note 2(f) of the 2017 Annual Financial Statements, as the condition is generally satisfied when title transfers to the customer. As such, upon adoption, this requirement under IFRS 15 resulted in no impact to our financial statements as the timing of revenue recognition on our gold bullion sales is unchanged. Concentrate Sales We assessed all of our existing concentrate sales agreements and determined that there is no change in the timing of revenue recognition, as control transfers to the smelting companies at the time of shipment, consistent with our current accounting policy as set out in Note 2(f) of the 2017 Annual Financial Statements. Although IFRS 15 identifies the shipping component associated with concentrate sales as a separate performance obligation, requiring a portion of the revenue to be deferred and only recognized once the shipment has reached the destination port, we have determined that the deferred revenue would be insignificant and thus, have not accounted for the shipping component as a separate performance obligation. IFRS 15 does not consider provisional price adjustments associated with concentrate sales to be revenue from contracts with customers as they arise from changes in market gold and copper prices between the shipment date and settlement date. As such, we have separately presented provisional price adjustments in Note 6 of these condensed interim consolidated financial statements in line with the requirements of IFRS 15. Streaming Agreements IFRS 15 requires that for contracts containing variable consideration, the transaction price be continually updated and re-allocated to the transferred goods and services. As a result, we have updated our accounting policy for revenue earned on streaming agreements such that we will treat the deferred revenue component as variable, requiring an adjustment to the transaction price per unit each time there is a change in the underlying production profile of a mine (typically in the fourth quarter of each year). The change in the transaction price per unit results in a retroactive adjustment to revenue in the period in which the change is made, reflecting the new production profile expected to be delivered under the streaming agreement. A corresponding retroactive adjustment is made to accretion expense, reflecting the impact of the change in the deferred revenue balance. The impact of the initial adoption of this change in accounting policy was an adjustment to reduce the opening deficit on January 1, 2018 of $64 million with a corresponding adjustment to reduce the deferred revenue balance. There was no impact to net income for the period. If in the second quarter and first half of 2018 we had continued to recognize revenue on streaming agreements in accordance with IAS 18, the amounts recognized for revenue, deferred revenue and interest expense would have been insignificantly different from those recognized in accordance with IFRS 15.

Disclosure of operating segments [line items]
Disclosure of entity's operating segments [text block]	SEGMENT INFORMATION Barrick’s business is organized into eleven individual minesites, one grouping of two minesites, one publicly traded company and one project. Barrick’s Chief Operating Decision Maker (“CODM”), the President, reviews the operating results, assesses performance and makes capital allocation decisions at the minesite, grouping, Company and/or project level. Therefore, each individual minesite, with the exception of Barrick Nevada, Acacia and the Pascua-Lama project are operating segments for financial reporting purposes. Our presentation of our reportable operating segments is four individual gold mines (Pueblo Viejo, Lagunas Norte, Veladero and Turquoise Ridge), Barrick Nevada, Acacia and our Pascua-Lama project. The remaining operating segments, our remaining gold and copper mines, have been grouped into an “other” category and will not be reported on individually.
