Mineral Reserves are reported on a 100% basis and exclude all mineral reserve material mined prior to July 1, 2023.
Specific gravity has been assumed on a dry basis.
(2)
(3) Tonnage and contained metal have been rounded to reflect the accuracy of the estimate and numbers may not sum exactly.
Values are inclusive of mining recovery and dilution. Values are determined as of delivery to the mill and therefore not inclusive of milling recoveries.
Mineral Reserves are reported within stope shapes using a variable cut-off basis with a Ag price of US$22/oz, Zn price of US$1.20/lb, Pb price of US$0.90/lb, Au price of US$1,700/oz and Cu price of
$3.50/lb.
The Mineral Reserve is reported on a fully diluted basis defined by mining method, stope geometry and ground conditions.
Contained Metal (CM) is calculated as follows:
Zn, Pb and Cu, CM (Mlb) = Tonnage (Mt) * Grade (%) / 100 * 2204.6
Ag and Au, CM (Moz) = Tonnage (Mt) * Grade (g/t) / 31.1035; multiply Au CM (Moz) by 1000 to obtain Au CM (koz)
The SEC definitions for Mineral Reserves in Regulation S-K 1300 were used for Mineral Reserve classification and are consistent with Canadian Institute of Mining, Metallurgy and Petroleum (CIM)
Definition Standards for Mineral Resources and Mineral Reserves (CIM (2014) definitions).
(9) Under SEC Regulation S-K 1300, a Mineral Reserve is defined as an estimate of tonnage and grade or quality of indicated and measured mineral resources that, in the opinion of the qualified person,
can be the basis of an economically viable project. More specifically, it is the economically mineable part of a measured or indicated mineral resource, which includes diluting materials and
allowances for losses that may occur when the material is mined or extracted.
(10) The Mineral Reserve estimates were prepared under the supervision of Mr. Stephan Blaho, P.Eng. an employee of WSP Canada Inc. who is the independent Qualified Person for these Mineral
Reserve estimates.
