Pan American Announces Revised PEA for the La Colorada Skarn Project, Positions La Colorada as a Future Top-Tier Silver Mine

Why It Matters

The project promises a long‑term, diversified metal supply at one of the lowest global silver costs, enhancing Pan American’s growth profile and offering investors strong, risk‑adjusted returns.

Key Takeaways

• Skarn project targets 15,000 tpd processing capacity
• Project aims 19.1M oz silver annually at peak
• After‑tax NPV $2.6B base, $5.2B upside
• AISC projected at $22.67 per ounce
• Payback period estimated 3‑4 years

Pulse Analysis

Pan American Silver’s revised Preliminary Economic Assessment for the La Colorada Skarn Project re‑imagines the 100 % owned Mexican asset as a 37‑year, 15,000‑tonne‑per‑day operation. The plan couples newly identified high‑grade veins with the existing skarn deposit, using conventional long‑hole open stoping and a new processing plant slated for commissioning around 2034. During construction, the legacy vein mine will continue producing, creating an “expanded” operation that could deliver roughly 19 million ounces of silver each year at peak. The extended mine life and integrated development aim to position La Colorada among the world’s lowest‑cost silver producers.

The base‑case economics show an after‑tax net present value of $2.6 billion and a 17 % internal rate of return, which more than double to $5.2 billion and 25 % under an upside price scenario that assumes $75 per ounce silver. All‑in sustaining costs are projected at $22.67 per ounce, thanks to substantial zinc and lead by‑product credits that also generate $653 million of annual free cash flow. These metrics place La Colorada in the top tier of global silver projects, offering investors a compelling risk‑adjusted return profile.

Pan American plans to fund the Skarn expansion entirely from operating cash flow, targeting a four‑year payback in the base case and three years in the upside. No additional permitting is required for the initial ramp, while permits for the processing plant and tailings facilities are in progress, de‑risking the schedule. Ongoing drilling, which has already added roughly 45,000 metres of skarn and 48,000 metres of vein intercepts, suggests further resource upside and the possibility of later‑stage block‑caving to extend life. For shareholders, the project delivers both a long‑term silver supply and diversified by‑product exposure to zinc and lead, aligning with rising industrial demand for these metals.
