Accounting Policies [Abstract]
Risks and Uncertainties	Risks and Uncertainties The Company continues to experience the impacts from geopolitical and macroeconomic pressures. With the resulting volatile environment, the Company continues to monitor inflationary conditions, the effects of certain countermeasures taken by central banks, and the potential for further supply chain disruptions relating to the Russian invasion of Ukraine and the COVID-19 pandemic, as well as an uncertain and evolving labor market. These factors could have further potential short- and, possibly, long-term material adverse impacts on the Company including, but not limited to, volatility in commodity prices and the prices for gold and other metals, changes in the equity and debt markets or country specific factors adversely impacting discount rates, significant cost inflation impacts on production, capital and asset retirement costs, logistical challenges, workforce interruptions and financial market disruptions, as well as potential impacts to estimated costs and timing of projects. The Company will continue to monitor and evaluate the potential impacts of the current and ongoing geopolitical and macroeconomic pressures. Depending on the duration and extent of ongoing global developments, these factors could materially impact the Company’s results of operations, cash flows and financial condition and could result in material impairment charges to the Company’s Property, plant and mine development, net; Inventories; Stockpiles and ore on leach pads; Investments; Deferred income tax assets; and Goodwill. Refer to Note 18 below for further information on risks and uncertainties that could have a potential impact on the Company as well as Note 2 of the Consolidated Financial Statements included in Part II of the Company's Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC on February 23, 2023. In June 2023, the Company announced the deferral of the full-funds investment decision for the Yanacocha Sulfides project in Peru for at least two years to the second half of 2026. The delay of the Yanacocha Sulfides project is intended to focus funds on current operations and other capital commitments while management assesses execution and project options, up to and including transitioning Yanacocha operations into full closure. To the extent that assessment determines that the project is no longer sufficiently profitable or economically feasible under the Company’s internal requirements, it would result in negative modifications to the Company's proven and probable reserves. Additionally, should the Company ultimately decide to forgo the development of Yanacocha Sulfides, the current carrying value of the assets under construction and other long-lived assets of the Yanacocha operations could become impaired and the timing of certain closure activities would be accelerated. As of September 30, 2023, the Yanacocha operations have total long-lived assets of approximately $1,163, inclusive of approximately $822 of assets under construction related to Yanacocha Sulfides. Refer also to the Company's risk factors under the titles "Estimates relating to projects and mine plans of existing operations are uncertain and we may incur higher costs and lower economic returns than estimated” and "Our long-lived assets and goodwill could become impaired, which could have a material non-cash adverse effect on our results of operations” included in Part I of the Company's Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC on February 23, 2023, for further information. Additionally, the Company continues to hold the Conga project in Peru, which we do not currently anticipate developing in the next ten years as we continue to assess Yanacocha Sulfides; accordingly, the Conga project remains in care and maintenance. Should we be unable to develop the Conga project or conclude that future development is not in the best interest of the business, we may consider other alternatives for the project, which may result in a future impairment charge for the remaining assets. The total assets at Conga were $896 at September 30, 2023. On June 7, 2023, the National Union of Mine and Metal Workers of the Mexican Republic (the "Union") notified the Company of a strike action. In response to the strike notice, the Company suspended operations at Peñasquito. Operations remained suspended throughout the third quarter of 2023. On October 13, 2023, the Company reached a definitive agreement with the Union that also received approval from the Mexican Labor Court. Per the agreement, the Company will pay Peñasquito workers a fixed amount equivalent to approximately 60% of wages for the duration of the strike, and an additional bonus of two months’ wages to be paid out in the second quarter of 2024 if, as a consequence of the strike, the Peñasquito mine reports no profit in 2023. Additionally, as a part of a separate annual negotiation under the Collective Bargaining Agreement, the Company agreed to an annual salary increase of 8% effective as of August 1, 2023, which is in line with the Mexican mining industry wage increases for 2023. Operations at Peñasquito will resume in the fourth quarter of 2023.
Use of Estimates	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the accounting for and recognition and disclosure of assets, liabilities, equity, revenues and expenses. The Company must make these estimates and assumptions because certain information used is dependent on future events, cannot be calculated with a high degree of precision from data available or simply cannot be readily calculated based on generally accepted methodologies. Actual results could differ from these estimates.
Reclassifications	Reclassifications Certain amounts and disclosures in prior years have been reclassified to conform to the current year presentation.
Recently Adopted Accounting Pronouncements and Federal Laws	Recently Adopted Accounting Pronouncements and Federal Laws Inflation Reduction Act In August 2022, the U.S. government enacted the Inflation Reduction Act of 2022 (the "IRA") into law. The IRA introduced an excise tax on stock repurchases of 1% of the fair market value of stock repurchases net of stock issued during the tax year and a corporate alternative minimum tax (the "Corporate AMT") of 15% on the adjusted financial statement income ("AFSI") of corporations with average AFSI exceeding $1 billion over a three-year period. The excise tax on stock repurchases is effective on net stock repurchases made after December 31, 2022 and the Corporate AMT is effective for tax periods beginning in fiscal year 2023. While waiting on pending Department of Treasury regulatory guidance, the Company is continuing to monitor developments. Based upon information known to date, the IRA had no material impact on the Company's current consolidated financial statements and is not expected to have a material impact on future consolidated financial statements, disclosures, or cash flows. Effects of Reference Rate Reform In March 2020, ASU No. 2020-04 was issued which provides optional guidance for a limited period of time to ease the potential burden on accounting for contract modifications caused by reference rate reform. In January 2021, ASU No. 2021-01 was issued which broadened the scope of ASU No. 2020-04 to include certain derivative instruments. In December 2022, ASU No. 2022-06 was issued which deferred the sunset date of ASU No. 2020-04. The guidance is effective for all entities as of March 12, 2020 through December 31, 2024. The guidance may be adopted over time as reference rate reform activities occur and should be applied on a prospective basis. The Company has completed its review of key contracts and does not expect the guidance to have a material impact to the consolidated financial statements or disclosures. The Company will continue to review new contracts to identify references to the LIBOR and implement adequate fallback provisions if not already implemented to mitigate the risks or impacts from the transition.
