Mineral Reserves

The Mineral Reserve estimate for Cobre Panama is entirely within the Measured and Indicated Mineral Resource estimate in the table above. It is consistent with the Mineral Reserve estimate methodology reported in the Cobre Panama Technical Report. The actual cut-off grade for the estimate varies due to variable processing recovery, but otherwise reflects a longer-term consensus copper price of $3.00/lb, a molybdenum price of $13.50/lb, a gold price of $1,200/oz and a silver price of $16.00/oz.

Cobre Panama had an estimated mine life of 31 years based on proven and probable reserves as of December 31, 2023.

Mineral Reserve - as at December 31, 2023 and reported based on a $3.00/lb Cu price
