TDG INITIATES PRELIMINARY ECONOMIC ASSESSMENT FOR THE SHASTA GOLD-SILVER PROJECT

TDG Gold Corp. has initiated a preliminary economic assessment (PEA) for its 100-per-cent-owned Shasta gold-silver project, located within the Greater Shasta-Newberry project area in the Toodoggone district of north-central British Columbia. Ausenco Engineering Canada ULC has been appointed as lead consultant for the PEA. The company is targeting completion of the study in Q3 2026.

Demonstrating potential economic viability

This inaugural study will establish the first economic benchmark for Shasta by evaluating the existing mineral resource within a preliminary mine plan and processing flowsheet whilst leveraging the company's infrastructure framework and current permits. In addition to establishing a baseline case for Shasta, the PEA will evaluate a broader development scenario that potentially incorporates material from the Mets mining lease mineralization as well as reprocessing of historical tailings from the Baker tailing storage facility.

The study will also provide shareholders with an initial set of project metrics, including potential scale, capital intensity, operating cost profile, mine life, economic sensitivities and opportunities for future optimization.

"A mineral resource is an important foundation, but investors need to understand what that resource may mean economically," stated Fletcher Morgan, director and chief executive officer of TDG. "The PEA is designed to provide that first disciplined economic framework for Shasta and to identify the key technical and economic drivers that will guide future work."

Corporate strategy update

Management believes that TDG's 100-per-cent-owned Toodoggone assets are currently undervalued given the success of the 2025 Aurora West drilling campaign, the gold-rich porphyry discovery potential, the existing mineral resource at Shasta (coupled with its existing permits, proximity and access route to Aurora) and the Mets mining lease containing some of the highest-grade, shallowest, thickest gold in the district with expansion potential.

TDG remains well capitalized with a near-term strategy focused on three core objectives:

1. Demonstrating value within the existing portfolio of assets, with the proposed Shasta PEA representing a key strategic objective;
2. Systematically advancing all assets toward value-unlocking milestones, including technical studies, permitting-related work and exploration advancement;
3. Delivering outperformance through discovery, with the company's fully financed 2026 drilling campaign at Anyox expected to conclude by the end of June, with assay results anticipated thereafter. In parallel, TDG continues to evaluate the potential for additional Aurora-style gold-rich copper porphyry targets in the vicinity of Aurora West.

2026 exploration program

TDG is also pleased to announce a fully financed 2026 porphyry focused program consisting of baseline and targeting studies designed to advance exploration along the northwest structural corridor extending from TDG's 100-per-cent-owned Aurora West project toward and including the Baker complex. Further details will follow by separate news release.

Management update

TDG also announces that Steven Kramar has departed as vice-president, exploration, and qualified person for the company. TDG thanks Mr. Kramar for his contributions and service over the past 4.5 years and wishes him every success in his future endeavours.

Paul Geddes, PGeo, senior vice-president, business development and strategy, has assumed oversight of the company's technical programs on an interim basis while TDG evaluates suitable candidates for the role.

About TDG Gold Corp.

TDG Gold is a significant mineral tenure holder in British Columbia's Golden Horseshoe, with over 60,000 hectares of exploration ground across the Toodoggone and Anyox mining districts.

In the Toodoggone district, TDG holds a 100-per-cent interest in approximately 50,000 hectares, including the past-producing Shasta and Baker mines, and the high-grade Mets developed prospect. The company has defined a gold-silver mineral resource estimate at Shasta within the 5.5-square-kilometre Greater Shasta-Newberry (GSN) target area, which remains open for expansion (news release Jan. 8, 2025). TDG is also advancing copper-gold porphyry exploration at Aurora West, contiguous with the AuRORA2 discovery (news release Jan. 17, 2025), and across TDG's broader 53 square km Baker complex.

At Anyox, TDG holds over 10,000 hectares, including the past-producing Hidden Creek copper mine, prospective for volcanogenic massive sulphide (VMS) mineralization.
