At December 31, 2025, the Company's economic interest in the Maracás Menchen Mine totaled 99.95% (December 31, 2024 - 99.4%). The remaining 0.05% economic interest is held by Companhia Baiana de Pesquisa Mineral ("CBPM") owned by the state of Bahia. CBPM retains a 3% net smelter royalty ("NSR") in the Maracás Menchen Mine. The property is also subject to a royalty of 2% on certain operating costs under the Brazilian Mining Act. Under a separate agreement, a third party receives a 2% NSR in the Maracás Menchen Mine.

The recoverable amount of the Mine Properties CGUs was determined by calculating the FVLCD. The FVLCD was determined by calculating the net present value of the estimated future cash flows (level 3 of the fair value hierarchy).
