PPX Mining Intersects High-Grade at Callanquitas Sulfide Zone with up to 49.52 G/T GOLD, 11,597 G/T Silver and 11.1% Copper
PRESS RELEASE
PPX MINING INTERSECTS HIGH-GRADE AT CALLANQUITAS SULFIDE ZONE WITH UP
TO 49.52 g/t GOLD, 11,597 g/t SILVER and 11.1% COPPER
Toronto – October 21, 2025 - PPX Mining Corp. (TSX.V PPX; BVL PPX - the “Company” or “PPX”)
is pleased to announce the continuation of its 4,300 meters diamond drilling program in coordination with
Proyectos la Patagonia S.A.C. (“PLP”), a partner co mpany. This drilling program is carried out inside the
mine, within two drilling chambers. The drilling was executed from the chamber 04, now reported (historic
DDH CA-24-07) and has the objective of testing Callanquitas East and the sulfide veins/breccias with four
drill holes CA-25-21, CA-25-22, CA-25-23 and CA-25-24. The drill hole CA-25-24 has partial grades, and
the company is expecting grades from the last 42 meters to come in later.
Drill hole CA-25-24 has three mineralized zones. Th e best mineralized intersection grades 8.63 g/t Au,
3756.2 g/t Ag and 0.7% Cu over 0.9 meters, includes grade of 22.38 g/t Au, 9619.5 g/t Ag and 1.9% Cu
over 0.3 meters, in the Callanquitas Este (mixed mi neralized zone). The second mineralized intersectio n
grades 10.98 g/t Au, 2189.1 g/t Ag and 2.3% Cu over 5.9 meters, includes grade of 17.33 g/t Au, 3888.3
g/t Ag and 3.9% Cu over 3.3 meters, and also includ es grade of 49.52 g/t Au, 11597.1 g/t Ag and 11.1%
Cu over 1.1 meters, tension vein of sulfide. The third mineralized intersection is still waiting for laboratory
results.
The drill hole CA-25-23 has three mineralized zones, the best intersection grades 12.33 g/t Au and 11.4 g/t
Ag over 2.4 meters, includes a grade of 27.43 g/t A u and 23.6 g/t Ag over 0.95 meters, Callanquitas Es te
(oxide mineralized zone). It also intercepted mineralized sections of low-grade tension veins.
The drill hole CA-25-22 intercepted a mineralized s ection grading 3.03 g/t Au and 13.2 g/t Ag over 1.5
meters at Callanquitas Este (mixed mineralized zone).
The drill hole CA-25-21 intercepted a mineralized section grading 0.62 g/t Au, 381.0 g/t Ag and 0.3% C u
over 1.25 meters and includes a grade of 2.78 g/t A u, 1897.0 g/t Ag and 1.3% Cu over 0.25 meters at
Callanquitas Este (sulfide zone).
The drill hole CA-25-24 was oriented at N66°E dippi ng -48°; drill hole CA-25-23 was oriented N43°E
dipping -14°; drill hole CA-25-22 was oriented N105°E dipping -48°; and drill hole CA-25-21 was oriented
N140°E dipping -39°. (See Plan View Figure 1, and Sections Figure 4). The drill holes CA-25-24 is in the
mixed – sulfide zone, CA-25-23 is in the oxide – mi xed zone, CA-25-22 is in the mixed zone, and CA-25-
21 is in the sulfide zone. See the intersections of mineralized zones below in the Table 1.

The drillhole CA-25-24 intercepted the Callanquitas Este structure and Tension Vein sulfide zone, located
6 meters south of CA-24-07 (DDH historic 07), a twi nned hole. The drillhole CA-25-23 intercepted the
Callanquitas Este structure and Tension Vein sulfide, located 150 meters north of 07. The drillhole CA-25-
22 intercepted the Callanquitas Este structure, loc ated 55 meters south of 07. The drillhole CA-25-21
intercepted the Callanquitas Este structure, located 103 meters south of 07. All boreholes are drilled from
chamber 04, located at an elevation of 2960 meters above sea level. (See Figure 1 and 2-5, Section: dr ill
holes and Longitudinal section).

The drillhole CA-25-24 intercepted the Callanquitas Este structure and Tension Vein sulfide zone, located
6 meters south of CA-24-07 (DDH historic 07). Has t hree mineralized zones, the most important is the
section grading 8.63 g/t Au, 3756.2 g/t Ag and 0.7% Cu over 0.9 meters, Callanquitas Este (mixed
mineralized goethite – pyrite, acanthite?). The sec ond section grades 10.98 g/t Au, 2189.1 g/t Ag and 2.3%
Cu over 5.9 meters, Tension Vein sulfide zone (pyrite, acanthite? chalcocite, chalcopyrite and bornite). The
third section is still awaiting laboratory results of the oxide zone (Goethite – limonite).

The drillhole CA-25-23 intercepted the Callanquitas Este structure and Tension Vein sulfide zone, located
150 meters north of 07 and 35 meter above. The best being the section grading 12.33 g/t Au and 11.4 g/ t
Ag over 2.4 meters, Callanquitas Este (oxide minera lized zone, goethite - limonite). It also intercepted
sections of low-grade tension veins (mixed zone).

The drillhole CA-25-22 intercepted the Callanquitas Este structure, located 55 meters south of 07 and at
the same height, and intercepted a mineralized section grading 3.03 g/t Au and 13.2 g/t Ag over 1.5 meters,
Callanquitas Este (mixed mineralized zone, goethite – limonite – pyrite).
Figure 4. Section: drill holes CA-25-22
The drillhole CA-25-21 intercepted the Callanquitas Este structure, located 103 meters south of 07 and 35
meter above. Intercepted a mineralized section grad ing 0.62 g/t Au, 381.0 g/t Ag and 0.3% Cu over 1.25
meters, includes a grade of 2.78 g/t Au, 1897.0 g/t Ag and 1.3% Cu over 0.25 meters, Callanquitas Este
(sulfide zone). The intercepts south of 07 (historical), near the axis of the anticline of the Bola de Igor hill,
and the increase in sulfides in Callanquitas Este i s important, as a reference we have the historical DDH
CA-11-16 and CA-12-55 (Figure 6. Longitudinal section).
