SUBSEQUENT EVENTS: | ​ ​ NOTE 15 — SUBSEQUENT EVENTS: ​ Dividends: ​ On October 19, 2023, the Board of Directors authorized a dividend of $1.00 per share payable on November 22, 2023 to shareholders of record at the close of business on November 8, 2023. ​ The Accidental Spill at Buenavista Mine of 2014 update: ​ In relation to the 2014 accidental spill of copper sulfate solution at a leaching pond in the Buenavista mine, on October 12, 2023, SEMARNAT publicly announced the filing of another criminal complaint, arguing that remediation of damages to the river was incomplete and compensation for said damages was insufficient. The Company has been directed to provide information regarding remediation activities and compensation for damages. In due course Buenavista del Cobre S.A. de C.V. will analyze this new complaint. Nonetheless, the Company strongly believes that it has duly completed all remediation and compensation-related activities as required by the competent Mexican authorities and as such, this new complaint is devoid of merit. ​
