Pan American Announces Revised PEA for the La Colorada Skarn Project, Positions La Colorada as a Future Top-tier Silver Mine
Pan American Silver pivots to high-grade phased development at La Colorada Skarn, targeting $2.6 billion NPV as Juanicipio acquisition fuels record cash flows.

The most recent news (March 24, 2026) details the results of a revised Preliminary Economic Assessment (PEA) for the La Colorada Skarn Project in Mexico. The company has shifted from a massive 50,000 tonnes per day (tpd) bulk mining concept to a phased 15,000 tpd development. This new plan targets higher-grade mineralization initially, resulting in an after-tax NPV (5%) of $2.6 billion and an IRR of 17% at base case prices. Peak annual production is projected at 19.1 million ounces of silver. This follows the March 5, 2025, announcement of new high-grade vein discoveries at the same site, which provided the geological basis for this strategic pivot.
The impact is Material - Positive. While the IRR of 17% is modest for a mining project of this scale, the strategic shift significantly de-risks the project by reducing initial capital intensity and focusing on high-grade "sweet spots." - Production Profile: The project transforms La Colorada into a global top-tier silver mine, adding 15.8 million ounces annually in the initial five years. - Cost Structure: Estimated AISC of negative $22.67/oz (due to zinc/lead credits) is a game-changer for the company’s overall margin profile. - Cash Flow: The projected $653 million in average annual incremental free cash flow represents a massive expansion compared to historical levels. - Strategic Alignment: This news validates the $2.1 billion acquisition of MAG Silver (completed Sept 2025), as the company uses the cash flow from Juanicipio to fund this internal growth without diluting shareholders further.
Pan American Silver is a leading Americas-focused precious metals producer. Its flagship project is now the La Colorada Skarn, a massive polymetallic deposit located beneath the existing La Colorada vein mine in Zacatecas, Mexico. The company also operates the high-grade Juanicipio mine (44% JV) and has a diversified portfolio across Peru, Canada, Brazil, Argentina, and Chile.
