The metallurgical program, conducted at SGS Lakefield, marks the first time mineralization from the W2 project has been subjected to conventional processing analysis. Using a composite sample with a head grade of 0.78% copper, researchers achieved a final concentrate grade of 28% copper with 92% recovery. The process demonstrated that chalcopyrite within the sample is well-liberated at a primary grind size of 100 microns, allowing for efficient upgrading through flotation.

PTX Metals Reports Strong Copper Recovery at W2 Project
Initial metallurgical testing at PTX Metals' W2 project in Ontario’s Ring of Fire has yielded high-grade results, with copper recoveries reaching 97 percent. The findings provide a technical foundation for the company as it advances exploration and evaluates the economic potential of its copper-nickel-PGE assets.
Beyond copper, the circuit captured significant precious metal values. Palladium and gold concentrations were upgraded by 21 times and 16 times, respectively, relative to the head grade. While the copper circuit performed robustly, a separate evaluation of nickel recovery showed lower efficiency, with the company noting that nickel is largely hosted within pyrrhotite. PTX Metals President and CEO Greg Ferron stated that these results validate the project's potential and will inform upcoming exploration strategies, including further testwork to enhance precious metal recovery and planned locked cycle testing to confirm circuit performance.
