TDG INTERSECTS HIGH-GRADE COPPER-GOLD MINERALIZATION AT AUWEST, TOODOGGONE

TDG Gold Corp. has released preliminary assays from the first drill hole completed at the AuWEST target within the company's 100-per-cent-owned Greater Shasta-Newberry (GSN) project located in the evolving Toodoggone district of Northern British Columbia. Drill hole TDG25-001 was drilled near-vertical and within 20 metres (m) of the boundary with Freeport McMoRan-Amarc Resources' (FMAR) AuRORA gold-rich copper porphyry-style discovery.

Highlights:

• TDG25-001 intersected 100.0 m grading 2.24 grams per tonne (g/t) gold (Au) and 0.38 per cent copper (Cu) from 308.0 m depth, contained within a broader 240.6 m zone grading 1.23 g/t Au and 0.23 per cent Cu (Table 1 for drill results summary).
• Four additional diamond drill holes completed: TDG25-002 to 585.0 m down hole depth, TDG25-003 to 671.0 m down hole depth, TDG 25-004 to 625.0 m down hole depth, TDG25-005 to 568.0 m all with assays pending.
• The first drill hole at southern drill pad No. 3, as well as the first stepout drill hole at drill pad No. 4 to the west of the boundary, are about to commence (based on the pad pattern set out in TDG news release Aug. 6, 2025).
• TDG is well financed with over $38-million cash in treasury including approximately $30-million of flow-through dollars -- sufficient to complete the currently proposed 2025 and 2026 programs.

All diamond drill holes so far have intersected similar mineralization consisting of disseminated and vein hosted sulphides extending over significant intervals and similar in appearance to the mineralization encountered in TDG25-001. Meanwhile, targeting studies continue within TDG's 12-kilometre (km) defined copper-gold porphyry structural corridor (TDG news release March 3, 2025), including soil sampling, mapping and greater than 30 line km of induced polarization (IP) geophysics completed over the entire GSN mineralized system. Results will be published once compiled.

Fletcher Morgan, TDG's chief executive officer, commented: "The Freeport-Amarc AuRORA discovery ranks among the highest-grade copper-gold porphyry systems recorded in B.C., positioning it as a significant new development in the region. Our priority this season is to determine the extent of the AuRORA-style mineralization on to our 100-per-cent-owned GSN project, located just one km from the Shasta gold-silver deposit. Preliminary assay results from drill hole No. 1, along with similar styles of mineralization observed in subsequent holes, point to a very encouraging start. We believe we may be in the early stages of outlining a new high-grade critical mineral system of substantial scale within B.C.'s prolific Golden Horseshoe."

Geology

The geological and hydrothermal characteristics of AuWEST discovery hole TDG25-001 are broadly consistent with generalized models for porphyry Cu-Au-Ag deposits in the Toodoggone. Mineralization is hosted by altered andesitic tuff. High-grade mineralization has an association with magnetite alteration and with a younger, overprinting, pervasive quartz-sericite/chlorite-pyrite alteration. Copper mineralization is mainly stockwork-style chalcopyrite, and precious metal mineralization has not yet been visually identified (too fine grained). The IP signature appears to be related to disseminated sulphides that overlie Cu-Au mineralization. The style of mineralization in TDG25-001 is broadly similar in appearance to that encountered in subsequent drill holes in the AuWEST target area.

QA/QC (quality assurance/quality control)

Samples for the GSN 2025 drill program followed chain of custody between collection, processing and delivery to a Bureau Veritas (BV) laboratory in Vancouver, B.C. The drill cores were delivered to the core shack at TDG's Baker mine site, and processed by geologists who inserted certified reference materials, blanks and duplicates (pulp and coarse) into the sampling sequence. The 2025 drill core was cut in half (one-half HQ core or NQ core) and placed in zip-tied polyurethane bags, then in security-sealed rice bags before being delivered directly from the Baker Mine site, to Bandstra Transportation Systems in Prince George, B.C., and ultimately to the BV laboratory in Vancouver, B.C. Samples were prepared and analyzed following procedures summarized in Table 3, where information about methodology can be found on the BV website, in the analytical guide.

Quality assurance and control (QA/QC) is maintained internally at the lab through rigorous use of internal certified reference materials, blanks and duplicates. An additional QA/QC program is under way by TDG Gold through the use of certified reference materials (CRMs), duplicate samples and blank samples that were blindly inserted into the sample batch. If a QA/QC sample returns an unacceptable value an investigation into the results is triggered and when deemed necessary, the samples that were tested in the batch with the failed QA/QC sample are retested.

About TDG Gold Corp.

TDG is a major mineral tenure holder in the Toodoggone district of north-central British Columbia, Canada, with 100-per-cent ownership of approximately 50,000 hectares of brownfield and greenfield exploration ground.

In 2023, TDG defined the 5.5-square-kilometre Greater Shasta-Newberry exploration target area (news release Jan. 25, 2023) which is located directly adjacent to the gold-rich copper porphyry AuRORA discovery announced by Freeport McMoran Inc. and Amarc Resources Ltd. (news release Jan. 17, 2025).

In 2024, TDG identified new copper-gold target areas over an expanded footprint covering approximately 53 square km known as the Baker complex (news release Feb. 28, 2024), including the North Quartz (news release April 2, 2024) and Trident (news release March 7, 2024) targets.

TDG's other Toodoggone projects within the property package include the former-producing, gold-silver Shasta and gold-silver-copper Baker mines, which produced intermittently between 1981 to 2012, and the historical high-grade gold Mets developed prospect, all of which are road accessible and, combined, have over 65,000 m of historical drilling. These projects have been advanced through compilation of historical data, new geological mapping, geochemical and geophysical surveys and, at Shasta, 13,250 m of modern HQ drill testing of the known mineralization occurrences and their potential extensions. In 2025, TDG published an updated mineral resource estimate for Shasta (news release Jan. 8, 2025), which remains open at depth and along strike.

In July, 2025, TDG closed the acquisition of Anyox Copper Ltd. (Anyox, news release July 14, 2025) which holds a combination of crown grants (100 per cent owned and optioned) and mineral claims totalling over 10,000 hectares including the former-producing Hidden Creek copper-gold mine -- all located within the Anyox peninsula at the southern tip of B.C.'s Golden Triangle. Anyox gives TDG access to a volcanogenic massive sulphide horizon within a significant past-producing district with copper-gold-lead-zinc-silver potential.

TDG is well financed with the priority exploration focus in 2025 to test for potential extensions of AuRORA-style mineralization onto TDG's 100-per-cent-owned GSN project.

We seek Safe Harbor.
