PTX METALS COMPLETES PHASE 1 DRILLING AND EXPLORATION PROGRAM AT SHINING TREE GOLD PROJECT

PTX Metals Inc. has provided an update on exploration activities at its Shining Tree gold project in the Timmins gold camp. The Shining Tree gold property is located in south Timmins along the Ridout-Tyrrell deformation zone (also known as RTDZ) in Ontario, Canada, covering 23,385 hectares, and the Heenan Mallard project, covering 5,700 hectares.

The company has completed phase 1 of its 2026 exploration program at Shining Tree (see news release dated June 3, 2026). In total, six drill holes were completed for 1,209 metres targeting the historic Ronda mineralization. Variable alteration and veining were observed in all holes; alteration and veining are not necessarily indicative of mineralization, and assay results are required to assess the significance of these observations. All core has been cut and sampled and submitted to Activation Laboratories Ltd. (Actlabs) in North Bay, Ont., and results are pending.

A concurrent soil sampling, prospecting and mapping program was undertaken over the northwestern portion of the Shining Tree gold project, along a previously untested section of the RTDZ, consisting of 321 soil samples and 59 grab samples. Soil sampling and prospecting focused on areas with historically identified anomalous rock chip geochemistry, within a geophysical defined corridor. The groundtruthing revealed several lithological domains and assay results from all samples are pending.
