PTX Metals Inc. Completes Surface Work at the Shining Tree Gold Property and Reports Multiple High-Grade Results from Surface Samples

Toronto, December 18, 2025 - PTX Metals Inc. (TSXV: PTX) (OTCQB: PANXF) (FSE: 9PX) ("PTX" or the "Company") is pleased to announce completion of a structurally-oriented, geological review and the new, high-resolution, airborne magnetics survey of the northern and central portion of its Shining Tree Gold Property, located in South Timmins along the Ridout-Tyrrell Deformation Zone (also known as "RTDZ") in Ontario, Canada. Sampling from the surface work resulted in multiple high-grade assays reported below. The highlights from the sampling were collected by SRK at the Rhonda and Herrick Targets, where samples returned up to 69.00 g/t Au and 18.82 g/t Au respectively.

Reporting initial discussion from the Shining Tree Gold Project

The primary objective of the comprehensive on-site review of the geology of the property's primary mineral showings is to create a clear understanding of the structural setting and controls on gold mineralization throughout the property and how they relate to regional geologic/structural patterns. Although the mineralized trends at each prospect are well-understood, how they relate to one another, and, more importantly, the regional geodynamic setting, requires further study.

Preliminary results from the structural review of the property suggests that available, regional geologic maps do not accurately depict the property's structural setting. During SRK's data collection and structural review of the property, 27 rock samples were taken for various purposes across the property (See Figure 1). The purposes of these samples were variable, with some of these samples being taken in attempt to reproduce historic, higher-grade Au values, while others were taken to develop understanding of the controls on localization of gold within the various veins and shear zones found across the property. Samples from both the Rhonda and Herrick areas returned the most significant results, returning up to 69.00 g/t and 18.82 g/t Au respectively.

The most comprehensive sampling was conducted at the Rhonda North Trench (See Figure 2) where samples were taken both along previously cut channels (i.e. resamples) and to the North of 2024 trenching extents along the projected vein trace. Resampling of high-grade channels from 2024 has demonstrated excellent reproducibility, suggesting higher Au grades are not the result of a nugget effect, but most likely the result of localized, but traceable, variability along the Rhonda structure that can be effectively targeted. Additionally, 4 grab samples of the Rhonda vein taken along strike and North of the 2024 Rhona North Trench demonstrate reliable continuation of gold values north of modern trenching and channel sampling. Results from these 4 samples ranged from 3.54 to 7.85 g/t Au.

All samples were hand-delivered to SGS Labs in Sudbury, Ontario who analyzed the samples for Au content via a 30/50g fire assay with atomic absorption spectroscopy (AAS) finish. SGS is an ISO 17025:2005 accredited testing laboratory. SGS performed an internal QA/QC program which includes the insertion of CRM's, blanks, sample repeats, and duplicate samples as is compliant with industry standards.

In addition to SRK's structural review and the aforementioned sampling, PTX commissioned Terrascope Inc. to conduct a high-resolution, drone magnetics survey across the central portion of PTX's Shining Tree claims. The survey wrapped up on December 12^th, 2025 with a total of 2783.5 line Km flown. The primary objective of the survey was to replace the current, low-resolution magnetics dataset used by the Company with a much higher-resolution dataset to aid with mapping the largely overburden-covered property. The current magnetics dataset is insufficient to delineate and target potentially gold-bearing structures; however, we expect this new magnetics survey, in combination with the structural information obtained from the SRK structural interpretation, will provide a sound foundation for developing successful exploration campaigns in the future.

The Company expects to release additional compilation of the structural analysis entering the year 2026. Those data will increase our understandings on lithologically- and structurally- controlled mineralization at the property and allow better definition of mineralized bodies to be drill tested and expanded.

W2 Update

As to conclude the year, the Company has also wrapped up its drilling program with approximately 1,200m drilled to date at its W2 Copper, Nickel, Platinum, Palladium (PGEs) Project, located in the Ring of Fire, Ontario. Initial core review shows sulfide-bearing gabbro with variation of disseminated to semi- and massive sulfide zones. Results are to be expected within Q1 2026.

Marketing and Advisory Contract

In December 2025, the Company has engaged Epstein Research, a private company headquartered in Upper Saddle, New Jersey, to provide marketing and advertising services to increase awareness of the Company. The cost of the 3-month agreement is $6,000 payable in advance. Epstein Research is arm's length to the Company and currently holds no securities in the Company.
