The Mineral Resources for the Cotabambas deposit are reported by copper equivalent cut-off grade of 0.15 %CuEq within an optimized pit constraint. The effective date of the Mineral Resources is 20 November 2023.
The principal metals grades were estimated by the ordinary kriging interpolation method on capped composite copper, gold, silver and molybdenum grades. No recoveries have been applied to the interpolated in-situ estimated grades.
Tables 1 and 2 present the mineral resources by domain for Indicated and Inferred mineral resources, respectively, within the optimized pit constraint.

| Note: Base case in bold. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Summation errors may occur due to rounding. Open pit mineral resources are reported within optimized constraining shell. Reported open pit cut-off grade is 0.15%CuEq. Breakeven open pit cut-off grade is 0.07% CuEq. Mineral Resources have an effective date of November 20, 2023. The Qualified Person responsible for this resource statement is Paul Daigle, P.Geo. (APGO, 1592). . Copper equivalent ( CuEq) is calculated using the equations: Oxide: CuEq = Cu + 0.4126*Au + 0.0038*Ag + 0.000*Mo; Mixed: CuEq = Cu + 0.5819*Au + 0.0063*Ag + 0.0003*Mo; Supergene: CuEq = Cu + 0.4498*Au + 0.0054*Ag + 0.0002*Mo; and Hypogene: CuEq = Cu + 0.4373*Au+0.0053*Ag+0.0002*Mo, based on the differentials of long range metal prices net of selling costs and metallurgical recoveries for gold and copper and silver. Metal prices for the CuEq formulas are: US$ 4.25/lb Cu, US$ 1,850 /Oz Au; US$ 23.00 /Oz Ag; and US$ 20.00 /lb Mo. Metal recoveries for the CuEq formulas are for Oxide: 0.0% Cu, 65% Au, 48% Ag, and 0.0% Mo; for Mixed: 60% Cu, 55% Au, 48% Ag, 40% Mo; for Supergene: 87.5% Cu, 62% Au, 60.4% Ag, 40% Mo; and for Hypogene: 90% Cu, 62% Au, 60.4% Ag and 40% Mo. Capping of grades varied between 0.50 %Cu and 3.7%Cu, 0.33 g/t Au and 2.3 g/t Au, and between 0.029%Mo and 0.060%Mo; on 6m composites by domain. The density varies between 2.20 g/cm3 and 2.66 g/cm3. Mineralization would be mined from open pit and treated using conventional flotation. Rounding in accordance with reporting guidelines may result in summation differences. *Oxide Cu - amenable to leaching; Oxide Cu-Au amenable to blending with sulphides (Au >0.25 g/t). |
