On 18 February 2025 Tailings Dam 15 at Sino-Metals Leach Zambia Limited's Chambishi facility (Copperbelt Province, Kalulushi District) failed, releasing acidic leach residue into the Chambishi Stream and the Mwambashi and Kafue Rivers; the company suspended operations and the Zambia Environmental Management Agency (ZEMA) commissioned an independent Environmental and Social Incident Impact Assessment (ESIIA). ZEMA received the consultant's final report on 19 December 2025 and held a public disclosure meeting in Kitwe on 6 January 2026. On 2 February 2026 the Ministry of Mines and Minerals Development announced that the investigation had concluded and that, once ZEMA's review of the findings is complete, stakeholders will be engaged to determine remediation and compensation modalities. Company clean-up operations began in March 2026.

Zambia's Parliament enacted the Property Transfer Tax (Amendment) Act No. 27 of 2024, assented to by President Hichilema on 24 December 2024 and in force from 1 January 2025. The Act introduces a first-ever dedicated Property Transfer Tax (PTT) schedule for mining rights: 10% of realised value on transfers of mining licences and mineral processing licences, and 8% on transfers of exploration licences. The measure directly raises the transaction cost of copper and cobalt mine acquisitions, stake transfers, and licence assignments across the Zambia Copperbelt. It is the fifth distinct fiscal or governance instrument enacted since 2024 in Zambia's rolling reform of its mining regulatory architecture.

The Pleno of Panama's Supreme Court of Justice unanimously declared Law 406 of 20 October 2023 — which ratified the renewed mining-concession contract between the Panamanian State and Minera Panamá S.A. (a subsidiary of Canada's First Quantum Minerals) — unconstitutional in its entirety. The ruling, delivered 27 November 2023 and published in Gaceta Oficial No. 29922 on 2 December 2023, found violations of 25 constitutional articles and ordered the orderly closure of the Cobre Panamá open-pit copper mine, which had produced ~350,000 t/yr of copper (~1% of global mined supply) and accounted for ~5% of Panama's GDP. The decision triggered a de-facto Panama-wide moratorium on new large-scale metals concessions and pending ICSID arbitration claims by First Quantum and Korea Resources / KORES (COFINPRO).

Chile enacted Ley No. 21.591 on 10 August 2023, establishing a two-component progressive mining royalty on large-scale copper producers with annual sales of 50,000 or more metric tons of fine copper (TMCF): a 1% ad valorem charge on annual copper sales, plus a progressive operating-margin component (RIOMA) at 8–26% of adjusted taxable mining operating income. The combined tax burden is capped at 46.5% of adjusted pre-tax earnings (45.5% for producers below 80,000 TMCF). The royalty entered force on 1 January 2024 and represents the first copper-taxation reform in Chile in over two decades, directly re-pricing output from BHP Escondida, Codelco, Antofagasta Minerals, and Anglo American operations — together accounting for a majority of Chile's ~5.3 Mt/year copper output.

The Income Tax (Amendment) Act, 2021 (Act No. 43 of 2021), assented 30 December 2021 and in force from 1 January 2022, re-introduces the deductibility of Mineral Royalty Tax (MRT) paid under the Mines and Minerals Development Act, 2015 when computing a mining company's taxable income for corporate income tax purposes. The Act removes mineral royalty from the list of non-deductible expenditures in section 44 of the Income Tax Act, reversing a non-deductibility rule that had applied since a 2015-era amendment and that mining companies and industry stakeholders had argued produced double taxation of the same revenue stream. Deductibility is conditional on the royalty having actually been paid for the charge year.
