Solaris Resources (TSX: SLS; NYSE American: SLS) President and CEO Matthew Rowlinson joins Kitco Mining at the 2025 NBF CEO Mining Conference in London to discuss the new pre-feasibility study and maiden reserve for the Warintza Project in Ecuador. The study outlines 240,000 tons per year of copper equivalent for the first 15 years, a $1.07 per pound C1 cash cost, an NPV of $4.6 billion, a 26 percent IRR, and $3.7 billion in initial capital. Rowlinson calls Warintza a “multi-generational asset” with 5.8 billion tons of resource, a 50-year mine life, and tier one, quartile one cost positioning supported by a 0.53:1 strip ratio, near-surface mineralisation, and strong Ecuadorian infrastructure.

Rowlinson explains that Warintza will be permitted in two stages, starting with a 22-year reserve life linked to the initial tailings facility. Additional tailings locations have already been identified to support the full 5.8 billion ton resource and extend mine life by roughly 30 years. Solaris aims to be fully permitted by the end of 2026, complete a feasibility study in early 2027, and move into a three-year build toward production. He adds that the PFS “opens a corridor” for strategic interest, and while Solaris is advancing its own development plan, the company remains open to discussions that maximise shareholder value.
