PPX obtains wide thicknesses exploration results in Callanquitas breccias

with up to 18.91 g/t Au and 1420.0 g/t Ag

Toronto – August 20, 2025 – PPX Mining Corp. (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 company. This program is being conducted underground, within two drilling

chambers. The first drilling chamber, No. 05, is designed to test the Callanquitas West breccia with drill

hole CA -25-17. The second drilling chamber, No. 04 (histo ric DDH CA -24-07), is aimed at testing

Callanquitas East and the sulfide veins/breccias with three drill holes: CA -25-18, CA-25-19, and CA-25-

20. Drill hole CA-25-20 has returned partial results, with assays from the final 60 meters still pending.

Drill hole CA -25-20 has identified three mineralized zones. The most significant includes an interval of

3.55 g/t Au and 205.5 g/t Ag over 4.2 meters, including 5.16 g/t Au and 306.0 g/t Ag over 2.0 meters.

Additional assay results from the last section of this hole are pending. Drill hole CA-25-19 also intersected

three mineralized zones, with the best interval returning 3.18 g/t Au and 257.7 g/t Ag over 11.1 meters,

including 5.62 g/t Au and 428.0 g/t Ag over 5.2 meters. Drill hole CA -25-18 intercepted a mineralized

section grading 1.53 g/t Au and 86.3 g/t Ag over 0.4 meters. At Callanquitas West, drill hole CA -25-17

intersected mineralization grading 5.00 g/t Au and 142.0 g/t Ag over 0.70 meters. (See Table 1).

Drill hole CA-25-20 was oriented N43°E with a dip of -30°; drill hole CA-25-19 was oriented N50°E with

a dip of -48°; drill hole CA -25-18 was oriented N65°E with a dip of -42°; and drill hole CA -25-17 was

oriented N229°E with a dip of -44°. (See Plan View, Figure 1, and Sections, Figure 4). Drill hole CA -25-

20 is located in the mixed–sulfide zone; CA-25-19 in the oxide–mixed–sulfide zone; CA-25-18 in the oxide

zone; and CA-25-17 in the oxide zone. See intersections of the mineralized zones summarized in Table 1.

The drillhole CA-25-17 intercepted the Callanquitas West structure, located in the northern area of the

historic drilling, and carried out in 2017 and 2024. The intercept of CA-25-17 is located 100 meters below

the drill hole CA -25-11 and 100 meters south of CA -25-13 (See Figure 2 and 3, Section: drill holes and

Longitudinal section).

Figure 2. Section: drill holes CA-25-17

The intercept from drillhole CA-25-17 confirmed the continuity of the Callanquitas West breccia, grading

5.00 g/t Au and 142.0 g/t Ag over 0.7 m. The drillhole CA-25-17 confirms the significant mineralization in

this northern area at 3,100 meters above sea level, demonstrating approximately 300 meters of

mineralization trending from the surface.

Callanquitas W est consists of several hydrothermal breccia events and faults that were mineralized at

different periods. Includes quartz arenites, siltstones, sandstones and dacites. The hydrothermal alteration

is predominantly sericite - quartz in these rocks. The mineralization, drilled by the drillhole CA-25-17, is

within mineralized Fe oxides (FeOx). These FeOx are located in the matrix of the hydrothermal breccia and

replaced by more than 10% goethite and limonite. In addition, some of the sections are totally replaced by

FeOx.

In the longitudinal section (Figure 3) we can observe that the mineralization in CA-25-17 continues at depth

about 100 m down from the drill hole CA-25-11, and 100 m to the south of CA-25-13.

Holes CA-25-18, CA-25-19 and CA -25-20 were drilled from the chamber 04 located at an elevation of

2960 meters above sea level and intercepted the Callanquitas East structure and tensional veins with sulfide

and mixed minerals. The intercepts of the three drill holes are located near the drill hole CA -24-07. See

Figure 4: Plan view, Figure 5, 6, and 7 and Figure 8 Longitudinal Section.

Figure 4. Plan view: location holes CA-25-18, CA-25-19 and CA-25-20

The drillhole CA-25-18 is located 15 meters from CA-24-07 (See Figure 5 Section) and intercepted 0.54

g/t Au and 83.2 g/t Ag over 2.5 m on the Callanquitas East breccia zone, predominantly iron oxides (OxFe).

No sulfides were intercepted.

Figure 5. Section: drill holes CA-25-18

The drillhole CA-25-19 intercepted three mineralized sections, the Callanquitas East breccia zone, and two

tensional sections. The grades are 3.18 g/t Au and 257.7 g/t Ag over 11.1 m, includes 8.32 g/t Au and 566.2

g/t Ag over 2.5 m (mixed zone); 1.94 g/t Au and 121.8 g/t Ag over 3.8 m , includes 4.31 g/t Au and 290.0

g/t Ag over 1.3 m (mixed zone); and 3.87 g/t Au and 3.9 g/t Ag over 1.7 m intercept (oxide zone).

Figure 6. Section: drill holes CA-25-19

The drillhole CA-25-20 intercepted three mineralized zones, the first two mineralized zones the assay

results are reported and the third mineralized zone at depth has missing assay results (sulfide zone). The
