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 January 2023. This update incorporated an additional 67,800 m of drilling for a total of 280,000 m of drilling in 522 drill holes.
The Measured & Indicated Resource grew by 35% to 1,132 Moz AgEq and the Inferred Resource grew by 40% to 119 Moz AgEq as summarized in the table below. This resource expansion was largely driven by exploration success at depth and in the northeast part of the deposit.
