Description
As at 31 December 2025
The Company's 100%-owned producing gold-silver-base metal mine in Oaxaca, Mexico, comprising six contiguous properties along a 55-kilometer stretch of the San Jose structural corridor in the Sierra Madre del Sur; two are production-stage (the Arista and Alta Gracia mines) and four are exploration-stage. Mining at the polymetallic Arista deposit (including the Switchback and Three Sisters vein systems) is by long-hole stoping and cut-and-fill, producing gold, silver, copper, lead and zinc. In 2025 a $150/tonne NSR cut-off (up from $120/tonne) was applied; combined Proven and Probable reserves fell from 1.12 Mt at year-end 2024 to 0.65 Mt at year-end 2025 on depletion (0.27 Mt) and engineering deductions (0.49 Mt), partly offset by 0.30 Mt of resource-to-reserve reclassification from the 2025 infill and grade-control program at Three Sisters and Arista. Reserves and resources are estimated under S-K 1300 (CIM 2014 definitions) using $3,000/oz gold, $38.00/oz silver, $4.54/lb copper, $0.95/lb lead and $1.25/lb zinc; resources are exclusive of reserves. A DDGM Technical Report Summary is filed as Exhibit 96.2.
