Trans Canada Gold appoints Paradigm Drilling for Harrison Lake project

VANCOUVER, BC / ACCESS Newswire / June 22, 2026 / Trans Canada Gold Corp. (TSX-V:TTG)(OTCQB:TTGXF) (" Trans Canada " or the " Company "), is pleased to announce that the Company has appointed Paradigm Drilling Ltd, of Kamloops B.C. as selected drill contractor for underground drilling at the Harrison Lake Gold Project. The Company will be using a Connors 20HH underground diamond drill, with 2.205" NTW Drill core. All underground work will be under the supervision of Carl von Einsiedel, P.Geo, Project Manager.

The Drill is currently being mobilized and is expected to be on-site and turning on the property shortly. The Company has now completed the installation of updated electrical underground facilities, underground drill pad set-ups, and is now ready for Phase 1- Diamond Drilling program at the Harrison Lake Gold Project. Contractors have completed all underground drill setups, upgrading underground electrical facilities, road access improvements and completing an upgraded all weather core shack/core sawing facility.

Follow up drilling will be based on the Projects previous successful historical drill programs targeting gold, with focusing on expanding previously discovered gold zones, determining continuity and orientation, locating higher grade extensions of mineralization, and preliminary testing of the remaining, untested mineralized and altered zones within the project areas. The Harrison Lake Gold Project is demonstrating the same geological characteristics as the Snowline Gold deposit situated in the Tintina Gold Belt in the Yukon. PROJECT FULLY PERMITTED FOR UNDERGROUND DRILLING/ 2026 EXPLORATION AND GOLD DRILLING STRATEGY Harrison Lake Gold Project in an advanced exploration and development setting, and is fully permitted targeting identified gold zones, increasing its gold resource.

Detailed drill planning and targeting is currently underway on the Harrison Lake Gold Project. The Company is well positioned to capture and to capitalize on the forecasted stable and ascending gold prices. Phase 1-Drilling - 6-hole program targeting the highest-grade gold zone around intercept DDH-84-52: 102 meters grading 3.54 g/t gold.

Phase 2 Drilling - 8-Hole drilling program targeting multiple high grade gold zones. DDH 88-76 which intersected 7.0 meters averaging 21.4 g/t and DDH 88-121 which intersected 9.0 meters averaging 13.5 g/t, are priority follow-ups. The Company currently has a non-compliant historical gold resource of 220,000 ounces of gold at the Harrison Lake Gold Project.

These historic estimates are disclosed solely for context. The historic estimates do not conform to current NI 43- 101 standards, are not classified as current mineral resources or mineral reserves, and should not be relied upon. A qualified person has not done sufficient work to classify the historic estimates as current mineral resources or mineral reserves.

Gold Targets Identified for Drilling and further Exploration The Company has identified Targets for further Exploration : 2 to 10 million tonnes of gold mineralized material Grading between 1.0 to 5.0 grams per tonne (g/t) gold This Target for further Exploration target is based on the current geological understating and historical drilling and identified mineralization, over several widely spaced intrusions over more than 2 kilometers of strike-length and over a combined vertical elevation range of more than 700 meters. The potential quantity and grade of this gold Target for Further Exploration is conceptual in nature , and there has been insufficient exploration to define a mineral resource and that it is uncertain if further exploration will result in the target being delineated as a mineral resource; HARRISON LAKE DISTRICT SCALE GOLD PROJECT - GEOLOGICAL HIGHLIGHTS - GOLD INTERCEPTS Harrison Lake district Scale Gold Project is located in an advanced gold exploration and development setting, which is fully permitted for targeting identified and known gold zones, in the expectation of increasing its gold resource. Detailed drill planning is currently underway on the Harrison Lake Gold Project located on Bear Mountain.
