## Minestarters Atlas summary

Solaris Resources has released a positive Pre-Feasibility Study \(PFS\) for its Warintza Project in Ecuador, reporting a post-tax NPV of US$4.6 billion and an IRR of 26%. The study outlines a 22-year mine life with first quartile operating costs and a low strip ratio. The company also announced a maiden Mineral Reserve of 1.3 billion tonnes and a significant 312% increase in Measured and Indicated Mineral Resources, with the project fully funded for a construction decision.

Reasoning: Solaris has published a highly positive Pre-Feasibility Study for its Warintza Project, demonstrating robust economics with a US$4.6bn post-tax NPV and 26% IRR, supported by a maiden Mineral Reserve and a substantial increase in Measured and Indicated Resources. The project benefits from a long mine life, low operating costs, and a low strip ratio, positioning it as a significant copper development opportunity. While the cut-off grade for the MRE was lowered, and some economic study conventions are undisclosed, the overall results are very strong.

- Positive factor: Strong post-tax NPV of US$4.6bn and IRR of 26% from a PFS

- Positive factor: Maiden Mineral Reserve of 1.3 billion tonnes established

- Positive factor: Significant increase \(312%\) in Measured plus Indicated Mineral Resources

- Positive factor: Long mine life of 22 years with potential for further extension

- Positive factor: First quartile cash costs \(AISC US$0.85/lb Cu for first 5 years\)

- Positive factor: Low strip ratio of 0.53:1 \(LOM\)

- Positive factor: Project is fully funded for construction decision

- Positive factor: Conventional open pit mining and processing methods

- Positive factor: Non-material levels of deleterious elements in concentrates

- Positive factor: Strong community and government support in Ecuador

- Negative factor: Cut-off grade for MRE was lowered compared to prior estimate, potentially inflating tonnage

- Negative factor: Inferred resources are a significant portion of the total resource \(2.1 Bt Inferred vs 3.7 Bt M+I\)

- Negative factor: Mine life is currently limited by TMF design capacity, not full resource potential

- Negative factor: IRR basis \(real/nominal\) and leverage basis \(levered/unlevered\) are not explicitly stated

- Negative factor: Price deck basis \(real/nominal\) is not explicitly stated

Low confidence — this extraction should be reviewed alongside the original source.

**Encumbered by Stream**

Polarity: negative

Definition: An existing stream or royalty reduces attributable NAV and restricts future financing.

Why it applies: Solaris has entered into a gold streaming agreement with Royal Gold Inc.

Evidence · text

Reasoning: The Indicated resource adds significant tonnage and copper content, representing a good level of geological confidence. The upgrade of Inferred to Indicated is a positive de-risking step, though the lowered cut-off grade is a minor concern. \(Expanded from multi-commodity resource table for completeness.\)

- Positive factor: High tonnage in Indicated category

## 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.
