Guinea's Mines Minister Bouna Sylla announced on 26 May 2025 the cancellation of 129 exploration permits for gold, bauxite, and diamonds that had expired between 2012 and 2024 and were held by non-compliant companies that had not fulfilled their statutory obligations. The measure is the fourth wave of post-coup mining cadastre cleanup under the CNRD/Doumbouya administration and follows two presidential decrees and a prior ministerial ordinance. Major affected operators include AngloGold Ashanti's Siguiri gold-mine exploration blocks, four gold permits held by Endeavour Mining, and Guinea Alumina Corporation's Nomba bauxite block; Axis International separately filed a USD 28.9 billion ICSID arbitration claim over bauxite-permit revocation in the same wave.

Guinea's Minister of Mines and the Minister of Finance and Budget issued a joint ministerial arrêté (approximately July–September 2022, official date recorded as 2022-09-01) establishing a mandatory bauxite reference price mechanism — the first fiscal-transparency instrument requiring all bauxite exporters operating in Guinea to apply a government-set benchmark FOB price on all export transactions. Any declared export price below the reference benchmark triggers an automatic upward adjustment to the benchmark level for purposes of royalty and tax computation, eliminating the transfer-pricing and underpricing loophole that the International Monetary Fund and the Intergovernmental Forum on Mining, Minerals, Metals and Sustainable Development (IGF) estimated caused >$1 billion per year in revenue leakage for the Guinean state. The mechanism operates separately from export quota and cap actions; it functions as a fiscal floor applicable across all operators. Chinese joint-venture operators — which control the majority of Guinea's bauxite production and export volumes — were the primary target given the prevalence of intracompany transfer pricing in Chinese-financed bauxite-to-aluminium supply chains.
