## Minestarters Atlas summary

Pan American Silver announced a Revised Preliminary Economic Assessment \(PEA\) for its La Colorada Skarn Project in Mexico, projecting strong economics and positioning it as a future top-tier silver mine. The PEA outlines an after-tax NPV \(5%\) of $2.6 billion and an IRR of 17% at base case prices, with a 4-year payback period. The project envisions a 37-year mine life, significantly increasing silver production and utilizing conventional long-hole open stoping and a new 15,000 tpd flotation plant, supported by high metallurgical recoveries for silver, zinc, and lead.

Reasoning: Pan American Silver announced a highly positive Revised PEA for its La Colorada Skarn Project, projecting strong economics, increased silver production, and extended mine life. The study outlines a robust financial case with a 17% IRR and $2.6 billion NPV \(5% after-tax\) at base case prices, supported by high metallurgical recoveries and a substantial resource base. While the PEA's reliance on inferred resources introduces some geological uncertainty, the overall outlook is very strong for the company's future production profile.

- Positive factor: Revised PEA shows strong economics with high NPV and IRR for the La Colorada Skarn Project.

- Positive factor: Significant increase in silver production and extended mine life, positioning it as a top-tier silver mine.

- Positive factor: Low AISC for silver, reflecting strong byproduct credits.

- Positive factor: Fast payback period for initial capital.

- Positive factor: Improved grades compared to prior PEA due to selective mining.

- Positive factor: Conventional mining method \(long-hole open stoping\) reduces technical risk.

- Positive factor: Metallurgical testwork demonstrates high recoveries for silver, zinc, and lead into high-quality concentrates.

- Positive factor: Substantial resource base, including significant indicated and inferred resources for both skarn and vein deposits.

- Negative factor: The PEA includes inferred mineral resources, which are considered geologically speculative and do not have demonstrated economic viability.

- Negative factor: The PEA is preliminary in nature and there is no certainty it will be realized.

- Negative factor: The resource estimate for the skarn deposit uses a sub-level caving \(SLC\) mining method for RPEEE, while the PEA uses long-hole open stoping, which could imply a disconnect in resource definition vs. mine plan.

Facts used in scoring: 37

**Inferred Heavy Feed**

Polarity: negative

Definition: Material Inferred share of LOM mill feed, or the share is undisclosed.

Why it applies: The Revised PEA explicitly states it includes inferred mineral resources, which are geologically speculative.

Evidence · text

> it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves

**High IRR**

Polarity: positive

Definition: Post-tax real unlevered IRR in the strong tier or better.

Why it applies: The after-tax IRR of 17% for the base case and 25% for the upside case are in the strong to exceptional tiers.

## How Atlas produces this analysis

Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
