Cordero hosts one of the largest mineral inventories of silver globally, along with significant volumes of gold, lead and zinc.
The Mineral Resource Estimate for Cordero was most recently updated in February 2024. This update incorporated an additional 33,400 m of drilling for a total of 310,900 m of drilling in 793 drill holes.
The Measured & Indicated Resource grew by 70 Moz AgEq to 1,202 Moz AgEq with the Inferred Resource decreased by 12 Moz AgEq to 155 Moz AgEq as summarized below. The overall expansion of the resource was largely driven by exploration success at depth and in the northeast part of the deposit.
