08:24 AM EST, 11/06/2025 (MT Newswires) -- Solaris Resources ( SLSR ) traded 2.5% higher at last look Thursday in NYSE American pre-market trading as the company reported the results of a pre-feasibility study for the Warintza project in Ecuador.

The study outlined a posttax net present value of US$4.62 billion based on an 8% discount rate, with a 26% internal rate of return and a 2.6-year payback period. Initial capital costs were estimated at $3.73 billion.

The project is expected to produce 4.5 million ounces of copper equivalent per year over the 22-year mine life.

The study also included a maiden mineral reserve estimate of 1.3 billion tonnes in the proven and probable category, grading 0.41% copper equivalent.

"In a copper market characterized by declining grades, few new discoveries, and increasingly complex permitting environments, Warintza is uniquely positioned to come online at the right moment, helping meet a critical global supply gap, while delivering strong returns to stakeholders," Chief Executive Officer Matthew Rowlinson said.
