Cut-off grade for Indicated & Inferred Resources for Guanacevi is 129 g/t Ag for Alex Breccia, Santa Cruz, North Porvenir and Porvenir Dos, 190 g/t AgEq for Porvenir Cuatro and 200 g/t AgEq or 50 g/t AgEq + 3.5% Pb + Zn combined for Noche Buena and Buena Fe.
Cut-off grade for Indicated & Inferred Resources for Guanajuato is 150 g/t AgEq
Cut-off grade for Indicated & Inferred Resources for Parral (Cometa) is USD$40 Net Smelter Return (NSR)
The NSR for Parral (Cometa) was calculated using metal prices of USD$12 per ounce of silver, USD$900 per ounce of gold, USD$0.50 per pound of lead, USD$0.50 per pound of zinc; metallurgical recoveries used were 71% for silver, 75% for gold, 80% for lead and 74% for zinc.
Silver-equivalencies in the table were calculated using a 65:1 ratio based on prices of USD$ 17 per ounce of silver and USD$1,100 per ounce of gold; no base metal credits are used for calculating silver-equivalencies.
Calculations or estimations inherently involve a degree of rounding and consequently introduce a margin of error. Where these occur, they are not considered to be material.
NOTE: Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. |
