Trans Canada Gold prepares drilling at Harrison Lake District Scale Gold Project

VANCOUVER, BC / ACCESS Newswire / June 4, 2026 / Trans Canada Gold Corp. (TSXV:TTG)(OTCQB:TTGXF) (" Trans Canada " or the " Company "), is pleased to announce that the Company is nearing completion and installation of updated electrical underground facilities, underground drill pad set-ups, and is preparing for Phase 1- Diamond Drilling program at the Harrison Lake Gold Project. Contractors are nearing completion of underground drill setups, upgrading underground electrical facilities, road access improvements and completing an upgraded all weather core shack/core sawing facility. An experienced drill contractor has been selected and drills have been mobilized to carry out the continuous underground drill program, and will be announced shortly.

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. 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. The Company is now well positioned to capture and to capitalize on the forecasted ascending gold prices. The property covers a 7-kilometre strike length of the gold rich Harrison Lake Structural Zone, with stockwork type gold mineralization within diorite intrusions (Jenner and Portal Zones) including DDH-84-52: 102 meters of 3.54 g/t gold.

Jenner and Portal Zones include 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. A corridor of similar diorite intrusions and "gold in soil" anomalies that extends for more than two kilometers to the south of the original gold discovery. Follow up drilling of some of these soil anomalies identified more diorite hosted stockwork type mineralization including DDH 88-130 which tested the Hill Zone and reportedly returned 30 meters averaging 3.0 g/t.

The style of mineralization is similar to the gold deposit model of the Tintina Gold Belt that straddles the Yukon - Alaska border and it has also been recognized that the mineralized diorite intrusions are localized along a regionally extensive shear zone adjacent to a large diorite batholith. Snowline Gold's recent discovery of the Valley deposit clearly demonstrates the potential of these types of occurrences. Tim Coupland, President and Chief Executive Officer, commented: "We are nearing final completion and preparing for Phase 1- Drilling at Harrison Lake unlocking the significant gold potential for the expansion on the district scale Harrison Lake Gold Project.
