Drilling Initiated at Transition Metals' Polymetallic Pike Warden Project, Yukon

Rhea-AI Summary

Transition Metals (OTC: TNTMF) reports that a diamond drill has been mobilized to its 100% optioned 4,100 ha Pike Warden Project in Yukon, with drilling initiated on October 6, 2025 to test seasonally accessible targets in the Copper Junction area.

The program will test targets from 17 drill-ready sites identified during the 2025 field season and aims to complete drilling in three to four weeks (weather dependent). Pike Warden sits on the Bennett Lake Caldera rim and has returned notable historical assays of up to 48.1 g/t Au, 11,270 g/t Ag, 7.49% Cu, and 2.37% Mo. IP and 2024 ZTEM surveys refined low-resistivity, elevated chargeability and porphyry-style targets. Summer rock assay results are pending; core will be logged and sampled in Whitehorse.

Sudbury, Ontario--(Newsfile Corp. - October 6, 2025) - Transition Metals Corp. (TSXV: XTM) ("Transition" or "the Company") reports that a diamond drill has been mobilized to its 100% optioned 4,100 ha Pike Warden Project, 70 km south of Whitehorse, Yukon. The drilling will test select seasonally accessible targets from the 17 drill-ready sites outlined in the Copper Junction area and identified during the Company's 2025 summer field program (see news release dated September 9, 2025).

Company CEO, Scott McLean, commented: "We are pleased to begin drill testing some of the targets we have defined on this project. The drilling will evaluate prospective areas under cover associated with structural features linked to the Bennett Lake Caldera Complex. The Copper Junction target area is surrounded by altered and fractured outcrop shedding elevated copper, molybdenum, gold, and silver into a large, covered area that coincides with complex geophysical signatures."

The Pike Warden Project sits on the northern rim of the Bennett Lake Caldera Complex, one of Canada's largest collapsed volcanic centres. This geological environment is prospective for the formation of large polymetallic porphyry copper and epithermal gold-silver systems. More than 25 polymetallic showings have been discovered to date at Pike Warden, returning assay values up to 48.1 g/t Au, 11,270 g/t Ag, 7.49% Cu, and 2.37% Mo.

Drilling Objectives

Multiple drill holes are planned this fall to test select targets within the Copper Junction area. This area is just one of the five large-scale targets identified on the property to date. Copper Junction hosts the densest cluster of elevated copper, molybdenum, and precious metal samples on the property (Figure 1).

Next Steps and Timing

Weather dependent, the company anticipates that the drilling will be completed within three to four weeks. All drill core will be transported to Whitehorse for detailed logging and sampling. Seasonal access conditions will be monitored throughout the program.

Assay results from rock samples collected during the summer program are pending. The sampling program identified at least two new showings. An IP survey further refined ZTEM-defined low-resistivity zones at Copper Junction and delineated a broad area of elevated chargeability and resistivity east of the Copper North target area. In this area, porphyry-style copper mineralization has been mapped and sampled, returning up to 5.58% Cu and 0.76 g/t Au in historical work, and up to 3.63% Cu and 0.55 g/t Au in grab samples collected since 2021.

About the Pike Warden Project

The Pike Warden Project, located 65 kilometres south of Whitehorse, Yukon, within the traditional territory of the Carcross/Tagish First Nation, is an emerging high-grade polymetallic epithermal gold-silver and porphyry copper property. The Company owns or has the option to own 100% interest in the 203 contiguous quartz claims covering an area of approximately 41 square kilometres.

The Project encompasses a combination of historic and recently discovered high-grade polymetallic occurrences, with bedrock and scree sampling across the property returning highlight values up to 11,270 g/t Ag, 48.1 g/t Au, 7.49% Cu, 59.6% Pb, 2.37% Mo, and 2.61% Zn. Furthermore, maiden drilling at the ERT Zone in 2022 returned percussion samples with highlight values up to 468 g/t Ag, 0.19 g/t Au, 163.5 ppm Cu, and 1,150 ppm Zn over 1.5 metre sample intervals (see news release dated January 16, 2023).

Mineralization on the Property appears to be spatially associated with large-scale structures, particularly at intersection nodes. Concentric structures interpreted as caldera collapse features are intruded by porphyritic ring dykes of the Bennett Lake Volcanic Complex. A second prominent structural trend identified are northeast-trending structures trending across the property, are believed to relate to a broader regional caldera collapse hinge zone. A combination of overlapping higher-temperature alteration styles, metal zonation, and zones of increased vein and fracture density appear to indicate that a mineralizing porphyry copper system(s) are exposed at varying erosional levels, interpreted to be controlled or bounded by the caldera collapse structures.
