TORONTO, ON / ACCESS Newswire / September 24, 2025 / PPX Mining Corp. (the "Company" or "PPX"; TSX.V:PPX; BVL:PPX) is pleased to announce that construction of the 350 tpd CIL and Flotation plant at its Igor Project in Peru to process gold and silver (dore and precious metal concentrate) continues at an accelerated pace, developing in parallel several activities such as: the installation of leach tanks, assembly of the crushing line, completion of final civil works, last weeks of earthworks in tailings and start of construction of auxiliary works, reaching an advance of the total plant to 55%.

The Company's EPC contractor began the assembly of the mechanical equipment in the milling area, while working on the unfinished civil works. Likewise, JPC Ingenieros began the installation of the leach tanks. In addition, JM&L continues with the preparation of the tailing management area to receive Geotubes. In addition, minor contractors continue with auxiliary components.

The photograph below shows a panoramic view of the construction of the plant as of September 20, 2025:

Installation

The EPC contractor has installed the two 7'x12' ball mills and jaw crusher. The mill motors and reduction gearboxes are also in place and the ring gears installed. Several metal structures such as the cyclone tower, fines hopper, coarse ore hopper, and conveyor belt support structures are also being assembled.

The following photograph, shows the mills:

Leach Tanks

The company JPC Ingenieros, a leader in the manufacture of leach tanks in Peru, has begun their assembly at site and it can be seen that the lower sections of four tanks are in place, the supports for the agitators (painted blue) are also in place for two of the tanks to the left of the following photograph. These sections will be raised on jacks and a further 3 sections welded in, to give a height of 23 feet (7 meters).

See next photograph show the leach tanks:

Tailings Management Area

The earthworks of the tailings management area are in the final stages (sufficient for the first year of operation) and the drainage channels and collection ponds are being finished. An impermeable membrane will be installed on the surface, together with a drain system using perforated plastic tubes covered with crushed stone. Geotubes will be paced on this surface and filled with tailings slurry, with process water being recovered by the drainage system and recycled to the process.

Geomembrane and geotextile materials purchased from China are scheduled to arrive in early October. The total progress to date is 65% of this first stage.

Civil Works

The EPC contractor continues with the last part of the civil works, with the construction of the retaining wall to allow trucks to tip ore into the coarse ore hopper and the circular pedestals for the water tanks and thickener, in addition to the bases of the desorption plant (rectangular), among others.

See photographs below - two circular water pedestals and circular thickener base:

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.
