PTX Metals strengthens the foundation for the next exploration phase at the Shining Tree Gold Property in Ontario with new structural models, high-grade surface samples and modern magnetic data.
PTX Metals: Structural work as the basis for the next exploration phase
PTX Metals (TSXV: PTX; FSE: 9PX) has completed this year’s field work on its Shining Tree gold property in the South Timmins gold district of Ontario and is now presenting initial results. The focus was on a structurally oriented geological review of the main occurrences and a new, high-resolution, airborne magnetic survey over the northern and central parts of the property.
PTX Metals’ Shining Tree Gold Project is located along the Ridout-Tyrrell Deformation Zone (RTDZ), a major regional structural corridor with known gold mineralization. The aim of the work was to better understand the geological architecture of the project and the structural controls on gold mineralization and to align them with the regional geology. Although the mineralized trends in individual sub-areas are already well described, their integration into a consistent, higher-level structural model required further detailed work.
As part of the campaign, 27 rock samples were taken in the field. In addition to verifying historical high-grade gold values, they were intended to provide insights into the spatial distribution and association of gold in quartz veins, shear zones and other structural elements. The Rhonda and Herrick targets were a particular focus – and it was precisely there that the highest gold grades of the campaign were achieved.
High-grade gold finds on Rhonda and Herrick
On the Rhonda and Herrick target, PTX Metals’ field work confirmed multiple high-grade gold samples at surface. Up to 69.00 g/t
The most extensive sampling was carried out at the Rhonda North Trench. There, the re-examination of older, already created channels was combined with samples taken north of the 2024 exposed trenches along the projected vein train. According to the company, the re-sampling of previous high-grade channels showed very good reproducibility of the gold grades. This suggests that the high values are not solely due to a nugget effect, but are linked to specific, structurally defined sections of the Rhonda system that can be specifically targeted.
In addition, four grab samples were taken along the strike of the Rhonda vein north of the previous trench boundaries. These samples yielded gold grades of between 3.54 and 7.85 g/t, indicating continued gold mineralization beyond the area investigated to date.
In both target areas – Rhonda and Herrick – PTX Metals sees this as evidence of contiguous, structurally controlled gold zones that could be systematically tested in future drilling programs and incorporated into resource modeling.
All samples were delivered directly by PTX Metals to SGS Labs in Sudbury, Ontario, where they were analyzed. SGS is an ISO 17025:2005 accredited laboratory and uses an internal QA/QC program with standards, blanks, repeat and duplicate analyses, as is standard in the industry.
High-resolution drone magnetics to reveal hidden structures
In parallel with the structural reinterpretation, PTX Metals commissioned Terrascope Inc. to conduct a high-resolution drone magnetic survey over the central part of the Shining Tree claims. This survey was completed on December 12, 2025; a total of 2,783.5 line kilometers were flown.
Background: A large part of the Shining Tree Gold property is characterized by overburden, which makes conventional mapping on the surface difficult. The company believes that the previously used, coarsely resolved magnetic data set was not sufficient to clearly define and specifically test potentially gold-bearing structures. The new, significantly higher-resolution magnetic data, together with the structural observations from SRK, will now serve as the basis for a revised geological model.
The aim is to more precisely trace shear zones, faults, fold structures and lithological boundaries and link them to known occurrences such as Rhonda, Herrick and Caswell. To this end, the locations of all samples (including those in the central areas of the Shining Tree project) were mapped and linked to the new geophysical data. From the beginning of 2026, PTX Metals plans to publish the complete structural evaluation and derive drilling targets for the next exploration phase.
The combination of detailed structural work, high-grade surface samples and modern magnetic data should allow mineralized bodies to be defined more precisely and future drilling to be planned in a much more targeted manner.
PTX Metals with additional leverage via the W2 project in the “Ring of Fire”
In addition to the Shining Tree Gold Project, PTX Metals is also reporting progress from the polymetallic W2 project in the Ring of Fire in Ontario. There, the company has drilled approximately 1,200 meters by the end of the year. Initial visual evaluations of the core show sulphide-bearing gabbro with zones of disseminated to semi-massive and massive sulphides.
PTX Metals’ W2 project is focused on copper, nickel, platinum and palladium (PGEs). Concrete analysis results from the ongoing campaign are still pending and are expected in the course of the first quarter of 2026. They should provide information on grades and continuity of the observed sulphide zones and serve as a basis for further planning of exploration work in the Ring of Fire.
