Resources
Note: Mineral reserves are based upon and included within the current mineral resource estimate.
Mineral reserves are estimated using a metal price forecast of US$1,647.50/oz for gold, US$21.64/oz for silver, US$3.60/lb for copper, US$0.92/lb for lead and US$1.14/lb for zinc
Mineral resources are not mineral reserves and do not have demonstrated economic viability. Mineral resource estimates include inferred mineral resources which are considered too speculative geologically to have economic considerations applied that
would enable them to be classified as mineral reserves. There is no certainty that inferred mineral resources will be converted to measured or indicated mineral resources.
Gold equivalency was estimated using metal selling prices of US$1,650/Oz Au, US$21.02/Oz Ag, US$0.91/Lb Pb, US$1.15/Lb Zn and US$3.70/Lb Cu.

Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
Zinc equivalent calculations used metal prices of US$1.20/lb for zinc, US$2.80/lb for copper, US$17/oz for silver, US$1,150/oz for gold and US$0.90/lb for lead and metallurgical recoveries of 70% for zinc, 68% for copper, 38% for silver, 25% for gold, and 60% for lead.
Metal price assumptions used in the Zn Eq calculation are the same assumptions used in establishing the cut-off for the estimates and reasonable prospects of eventual economic extraction.
A 5.5% Zn Eq cut-off in bold is considered to be appropriate for the sub-level caving mining method planned for extraction of the mineralization in the various deposits. All Mineral Resource estimates, cut-offs and metallurgical recoveries are subject to change as
a consequence of more detailed economic analyses that would be required in Pre-Feasibility and Feasibility studies. The 5.5% Zn Eq cut-off in bold is considered the base case Mineral Resource estimate. Other estimates are reported in the context of cut-off grade
sensitivity analysis.
