PTX Metals Inc. (TSX-V: PTX) (OTCQB: PANXF) (FSE: 9PX), a mineral exploration company focused on Cu-Ni-Au-PGE and Gold projects in Ontario, is pleased to release the following assay results from its Phase 1 of 2025 drilling program at the W2 Cu-Ni-PGE and Gold Project located in the Ring of Fire, northwestern Ontario, Canada. Subsequently to the previous press release of May 27^th, 2025, drill holes W225-08 and W225-12 are now being reported.

Drilling has confirmed the presence of high-grade copper in multiple intervals above 1% Cu and consistent copper and nickel mineralization over broad widths in both drill holes W225-08 and W225-12. Additionally, drillhole W225-12 located in the CA2 zone of the Central Target, notably intercepted higher-grade palladium and platinum mineralization. This drill program has shown an improvement of both widths and grades from historical holes.

Results from PTX’s drilling include intersecting wide intercepts of encouraging grades near surface that continue to validate the potential of the exploration target issued last September, supporting a potential large bulk tonnage project. The results demonstrate a larger-scale system (~8 km in strike length) that encompasses the CA zones and the AP zones and a current goal to build a continuous system between CA1 and CA2 zones (see 3D geological model interpretation released on May 7^th).

Highlights – Drill Holes W225-08 and W225-12:

Drillhole W225-08 intercepted a core length of 97.05m in the CA1 zone of near surface mineralization starting at 26.95m directly after the overburden. Drill hole W225-12, located in the CA2 zone 2.92 km to the East of CA1 zone, intersected 88.00m of sulphide mineralization demonstrating consistency of the mineralized body within the different identified zones.

• The highest grades by individual commodity in the two holes combined include: 1.80% copper, 0.74% nickel, 0.52 g/t gold, 1.05 g/t palladium and 0.55 g/t platinum and Cobalt 0.15%

Drillhole W225-08

• • The hole intercepted a broad zone of 97.05m of near surface mineralization grading at 0.41% (Cu+Ni) and 0.10 g/t (Au+Pt+Pd), starting at 26.95m directly after the overburden. For further notes on sum of commodities see [1] below.

    • 0.82% Cu, 0.34% Ni and 0.14 g/t (Au+Pt+Pd) over 1.50m from 80.00m to 81.50m
  • Toward the end of the hole at depth 137.94m to 138.44m, a smaller interval of 0.50m at 0.73% Cu, 0.20g/t Au and 0.41 g/t Pd was intercepted showing potential for another mineralized zone at depth.

Historical drilling was selective in assaying for all commodities and selective sampling procedures occurred. As a result, the Company has systematically assayed for Copper, Nickel, Gold, Palladium, Platinum and Cobalt and is now not reporting using Metal Equivalents and seen substantial improvements in the widths of mineralization with these practices. Additionally, for simplification purposes, Cu+Ni (%) and Au+Pt+Pd (g/t) are reported below as the arithmetic sum of individual commodity per interval chosen. Individual grades by commodity are also shown in table 1.

Drill hole Analysis and Images:

Drillhole W225-08, drilled into the CA1 Zone, was designed to infill and as a step out of hole 54004-0 drilled by Inco to the south, which reported some of the highest copper grade on the property [1] and a wide interval of consistent Nickel grade. The target was successfully intercepted starting from surface below the overburden at 26.95m depth and with 97.05m of mineralization within the main interval. Drilling has confirmed the presence of high-grade copper in multiple intervals above 1% Cu with up to 1.80% Cu and Nickel ranging between 0.20% and 0.70% within the mineralized interval as reported in Table 1 and in Figure 2.

Drillhole W225-12 was designed to infill and as a step out of 130m to the east of W225-11 previously reported on May 27^th, 2025. Both of PTX’s holes showed not only higher-grade intervals but also a significant amount of palladium and platinum, where high-grade of 1.05g/t Pd was assayed in hole W225-12. Overall, the polymetallic system including copper, nickel, gold, platinum, palladium and cobalt occurs within consistent and similar wide intervals as shown in Figure 3.

QAQC:

Samples (NQ core diameter = 4.76 cm) were cut using a diamond blade saw, inserted into labeled bags, and delivered by representatives of PTX to Activation Laboratories Ltd. in Thunder Bay, Ontario. Activation Laboratories Ltd. is an ISO 17025:2005 accredited testing laboratory.

Samples were analyzed for Au, Pt, and Pd using the lead fire-assay 1C-OES package, and multi-element analysis was completed by near-total digestion (four-acid) with an ICP-OES finish (1F2 package). For over-range samples (Cu, Ni) over 1% Cu or Nickel, the 8-4 Acid Near Total ICP-OES method was utilized.

PTX inserted standards and blanks and performs duplicate analysis as part of its QA/QC program. Activation Laboratories also performs an internal QA/QC program which includes the insertion of CRM’s, blanks, sample repeats, and duplicate samples.
