PPX Mining Continues Advancing Construction of Its Gold and Silver Processing Plant

TORONTO, ON / ACCESS Newswire / November 12, 2025 / PPX Mining Corp. (TSX.V:PPX)(BVL:PPX) (the "Company" or "PPX") is pleased to announce that construction of PPX Mining's processing plant continues to advance steadily, with major milestones achieved across all operational areas. Civil works for the leaching zone are complete and tank installation is underway, while crushing and milling components are nearing full assembly with equipment largely on site. Fabrication of reagent tanks and flotation equipment has been finalized, with installation progressing on schedule. Desorption units, geotube tailings infrastructure, and key laboratory facilities are currently under construction, supported by the arrival of geotextile materials and laboratory instruments. Complementing these efforts, the Company has commenced the construction of auxiliary works, including a 200-square-meter analytical/metallurgical laboratory and the first 370-meters of reinforced concrete security perimeter wall, both expected to be completed by year-end.

Leaching Area

The civil works for the leaching area have been completed, and the installation of tanks, managed by JPC Ingenieros, has begun. All metal-mechanical materials are 100% purchased and delivered to site. Welding and assembly of the first four tanks are being finalized, while the bases for the remaining four tanks are underway, with completion expected by mid-December.

About PPX Mining Corp:

PPX Mining Corp. (TSX.V: PPX.V, SSE: PPX, BVL: PPX) is a Canadian exploration and development company with assets in northern Peru. The Company's 100% owned Igor gold and silver project is located in the prolific northern Peruvian gold belt in the department of La Libertad. PPX is pursuing a two-pronged strategy to further develop and explore Project Igor. The Callanquitas structure is open along strike and at depth. Parallel structures have not yet been explored. The new discoveries in Portachuelos in 2018, as well as the exploration targets in Domo and Tesoros, show that the Igor Project is becoming a district-scale project with multiple deposits and mineralized zones. Evaluating mineral development alternatives in parallel with exploration drilling will provide dual catalysts for growth and increased shareholder value.
