Source: Apex Geoscience Technical Report on the Topia Property, Durango, Mexico May 6, 2022 – All resources are historical. A qualified person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves; and the issuer is not treating the historical estimate as current mineral resources or mineral reserves.
For additional details refer to the technical report dated March 7, 2024 (effective date December 31, 2023) titled “Technical Report on the Topia Property, Durango, Mexico” available on SEDAR+.
Historical Mineral Resources were estimated using metal prices of US$1,650/oz Au, US$20.00/oz Ag, US$0.85/lb Pb, and US$1.20/lb Zn; and metallurgical recoveries of 92.4% for Ag, 55.4% for Au, 94.3% for Pb, and 90.5% for Zn. AgEq ounces were calculated using 85:1 Ag:Au ratio, and ratios of 1:0.041 and 1:0.049 for the price/ounce of silver to price/pound of lead and zinc, respectively. The ratios are reflective of average metal prices for 2021.
