PTX Metals Inc. Intercepts 235m of Mineralization, the Widest Near-Surface Mineralized Interval to Date at Its W2 Cu-Ni-PGE and Gold Project

Toronto, Ontario--(Newsfile Corp. - May 27, 2025) - PTX Metals Inc. (TSXV: PTX) (OTCQB: PANXF) (FSE: 9PX) ("PTX" or the "Company"), a mineral exploration company focused on Cu-Ni-Au-PGE and Gold projects in Ontario, announces initial assay results from two drill holes of 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 (the "W2 Project"). This marks the first drill campaign in the CA zones (CA1 and CA2 see attached image) since 1990s, aiming to infill, confirm and expand historical reported drill results. Assays are pending for the additional drillholes.

The W2 Project drilling strategy targets near-surface copper-bearing disseminated sulphide mineralization and aims to demonstrate the continuity of the system along strike and at depth. Based on the current and historical drilling, combined with geophysical surveys, the central target area is interpreted to extend for approximately 8 km in strike length and remains open at depth (see press release of May 7^th, 2025).

The second objective of the exploration program was to better delineate semi-massive to massive sulfides mineralization as well as Nickel sulphides in the CA zones reported by historical mineral exploration work, and to evaluate the presence of Gold and Platinum Group Elements (PGEs) that were not assayed in many historical drill holes.

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.

Highlights - Drill Holes W225-10 and W225-11

• Drillhole W225-10 intercepted the widest mineralized near-surface intercept to date, which reports a width of 235.14 m of mineralization, starting directly after the overburden at 19.86m. Located 3 km away to the east, drillhole W225-11 intersected a zone of higher-grade near surface mineralization demonstrating consistence along strike of the targeted geophysical anomaly connecting CA1 and CA2 zones (see Figure 1).

• Highest-grades by individual commodity in the two holes combined include: 1.81% Copper, 1.48% Nickel, 5.59 g/t Gold, 0.66 g/t Platinum and 0.57 g/t Palladium and Cobalt 0.13%

• Drillhole W225-11 intercepted the CA2 Zone 58.00 of core length from 37.00 m to 95.00 m and returned 0.27% Cu, 0.21% Ni, and 0.23 g/t Au+Pt+Pd, including multiple shorter higher-grade intervals such as:
  • 17.00 m of 0.50% Cu, 0.40% Ni and 0.33 g/t (Au+Pt+Pd) and 2.07 m of 1.32% Cu, 0.26% Ni, and 0.20 g/t (Au+Pt+Pd) (see Table 1 below for details):

• Drillhole W225-10 intercepted a near-surface significant number of continuous higher-grade intervals throughout the length of the 235.14 m that reported 0.17% Cu, 0.08% Ni and 0.18 g/t (Au+Pt+Pd) to 255.00 m, including multiple higher-grade intervals:
  • 26.14 m of 0.30% Cu, 0.07% Ni, and 0.14 g/t (Au+Pt+Pd)
  • 5.36 m of 0.59% Cu, 0.14% Ni and 0.29 g/t (Au+Pt+Pd)
  • 29.00 m of 0.25% Cu, 0.15% Ni and 0.14 g/t (Au+Pt+Pd)
  • 42.00 m at 0.22% Cu, 0.12% Ni and 0.15 g/t (Au+Pt+Pd)
  • 13.00 m of 0.30% Cu, 0.14% Ni, and 0.36 g/t (Au+Pt+Pd)
  • 6.60 m of 0.43% Cu, 0.20% Ni and 0.42 g/t (Au+Pt+Pd)
  • 0.68 m of 1.50% Cu, 0.29% Ni and 0.43 g/t (Au+Pt+Pd)

• Systematic sampling in both holes shows improved widths over nearby historical drillholes suggesting potential to improve width and tonnage of the mineralized zones at depth (Figure 2 and 3). Additionally, a repeating pattern of higher-grade Cu-Ni mineralization within the broader hole has been observed throughout the holes, suggesting that further mineralization could extend at depth. Hole W225-10 intercepted 0.79% (Cu+Ni) and 0.54 g/t (Au+Pt+Pd) at 247.00-249.00m.

Greg Ferron, President and CEO of PTX Metals, stated: "We are very encouraged by the results from drill holes W225-10 and W225-11 that were drilled into CA1 and CA2 zones respectively at our W2 Cu-Ni-PGE and Gold Project. These results start validating the exploration target issued last September, which outlines a large near-surface project and improves the understanding of our exploration model. Hole W225-10 and W225-11 intersected broader and deeper zones of mineralization than previously reported, demonstrating improved continuity and the potential to significantly expand both CA1 and CA2 zone at depth."

Drillhole W225-10, drilled into the CA1 Zone, was designed as an infill and expansion hole near historical holes 54004-0 and 54007-0 drilled by Inco. The new results not only confirmed the continuity of the mineralized horizon but defined a wider and deeper intercept than previously reported in historical data (Figure 2). Historical holes 54007-0 and 54005-0 were drilled at shallower depth and weren't sampled throughout (up to 37.85m in hole 54007-0 and 42.43m in hole 54005-0 not sampled). PTX's more comprehensive sampling in W225-10 demonstrates better continuity of the near-surface mineralization over a thicker interval; this could potentially lead to a growth upside toward the exploration target and toward a potential resource estimate. Follow-up drilling is being planned to further test continuity and grade of the CA1 zone.

Drillhole W225-11 was designed to infill and to validate historical drill holes, which duplicated holes 54002-0 drilled by Inco (noting with small adjustment in the azimuth and dip, allowing better definition of the true width). Also, historical Inco holes at CA2 zone were selectively sampled as well (Figure 3), which left largely the possibility for more positive results. Geochemically, copper, nickel, cobalt and PGEs seem to be correlated well over wide intercepts, while gold seems more erratic, even though Gold is present at lower grade in most of the drill holes. Further drilling in this area will be followed to confirm and to try to build a larger mineralized system.

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.
