Orla Mining Cerro Quema reserve and resource estimation
The following tables presents the mineral reserve and mineral resource estimation for the Cerro Quema Oxide Project.
Proven and probable mineral reserves amount to 21.7 million tonnes at 0.80 g/t gold and 2.18 g/t silver for 0.56 million contained gold ounces and 1.53 million contained silver ounces.
The mineral reserve was estimated based on a gold price of US$1,250 per ounce and a silver price of US$17 per ounce while the mineral resource was estimated based on a gold price of US$2,000 per ounce and a silver price of US$26 per ounce.
The July 28, 2021 news release contained a typographical error in the calculation of gold and silver ounces in the inferred mineral resource category which has been corrected in the material change report dated August 9, 2021 and below. Tonnes and grades were correctly stated and remain unchanged.
