Yecora Mineral Resource Estimate
Highlights:
- Indicated resources of 25.3 Mt at 0.30% copper, 28.5 g/t silver, and 749 ppm molybdenum (0.79% CuEq grade),for a contained 444 Mlb of Cu-equivalent
- Inferred resources of 11.2 Mt at 0.30% copper, 24.2 g/t silver, and 831 ppm molybdenum (0.78% CuEq grade),for a contained 193 Mlb of Cu-equivalent
- The resource estimate is based on 34 diamond drill holes and 8 reverse circulation drill holes completed between 2014 and 2022 for 14,006 m of drilling in total
- Preliminary metallurgical test work projected a copper concentrate grade of 20-25% with a recovery of approximately 90% and containing 75 to 85% of the silver. The molybdenum concentrate grade was projected to be 50-55% with a recovery of 80 to 90%. Future testing will determine the feasibility of recovering lead and zinc to a separate concentrate, and thus zinc and lead were not included in the current resource estimate

Notes:
- Mineral Resources are not Mineral Reserves and have not demonstrated economic viability
- The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues
- The Mineral Resources were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves. Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council
- Numbers may not add due to rounding
- Mt are 1,000,000 metric tonnes; koz are 1,000 troy ounces; Mlbs are 1,000,000 imperial pounds; g/t are grams per metric tonne
