Trans Canada Gold Has Successfully Completed Phase 1- Drilling at the Harrison Lake District Scale Gold Project and Completes Updated Underground Mine Refurbishment

VANCOUVER, BC / ACCESS Newswire / August 20, 2026 / Trans Canada Gold Corp. (TSXV:TTG)(OTCQB:TTGXF) ("Trans Canada" or the "Company") is pleased to announce that the Company has successfully completed its Phase-1 underground drilling on Bear Mountain at the Harrison Lake Gold Project located in Southwestern B.C. Paradigm Drilling Ltd, of Kamloops B.C., was the drill contractor for underground drilling at the Harrison Lake Gold Project. The Company also completed an underground Mine refurbishment and successfully passed a Mine inspection by the BC Ministry of Mines. All drill core is being safely secured and stored, catalogued and prepared for analysis, splitting and logging. The core will be analyzed for gold by the PhotonAssay method, which is now the standard method to analyse for high-grade, nuggety gold. Previous use of this assay method on the property has materially increased grades in the tested samples. This work will potentially increase the project's gold grade. All underground work and drilling was under the supervision of Carl von Einsiedel, P.Geo, Project Manager.

In addition to drilling, the Company has adopted the phased long-term investment approach, which requires updating facilities, and adopting an ongoing refurbishment approach, which will allow for a responsible deployment of capital to invest in required infrastructure updates, required to unlock the projects long-term value. The Company has successfully completed an underground Mine refurbishment program, including the installation of updated electrical underground facilities, underground drill pad set-ups for future diamond drilling, and is now ready for the Phase 2 Diamond Drilling program at the Harrison Lake Gold Project. Additional infrastructure upgrades are expected to rapidly optimize all underground drill setups, underground electrical facilities, underground access improvements and completed an upgraded an all-weather core shack/core sawing facility which is currently being utilized and preparing core for assaying. Phase 1 drilling was based on the project's previous successful historical drill programs targeting gold, 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 is located in an advanced exploration and development setting, and is fully permitted for drilling and targeting identified known gold zones. Detailed drill planning for Phase 2, 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 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 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 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 excited to have successfully completed Phase 1 - Drilling at Harrison Lake, unlocking the significant gold potential for the expansion on the district-scale Harrison Lake Gold Project. British Columbia is rapidly being recognized as a Tier 1, Jurisdictional and mining-friendly asset destination now, fast-tracking and advancing mining development projects and announcing billions in investments in an Ottawa-B.C. growth initiative favoring all Canadians. The Company is currently reviewing and improving operating efficiency and lowering operating costs intended to maximize future drilling opportunities.

"The Company is currently updating the high-quality GIS database of exploration and drilling data available to our staff of seasoned mining professionals and underground diamond drillers delivering drill results. Trans Canada Gold and its geological team is now positioned to expand the district-scale gold potential of the property and to potentially confirm higher-average gold grades with modern assay methods. The Company will embark on a program to accelerate investor awareness and branding of our unique gold opportunity, in this precious metal super-cycle."
