TDG Gold Intersects 164 m grading

1.04 g/t Au, 0.24% Cu at Aurora West, Toodoggone

Including 1.7 g/t Au, 2 g/t Ag, 0.32% Cu over 67 m

Vancouver, British Columbia, October 15, 2025 – TDG Gold Corp. (TSXV: TDG | OTCQX: TDGGF)

(the “Company” or “TDG”) is pleased to report additional assay results from its fully funded Phase

I exploratory drilling program at the Aurora West target within TDG’s Greater Shasta -Newberry

(“GSN”) project. The ongoing Phase I exploratory program now involves three drill rigs on the

Company’s 100% owned flagship GSN Project in the Toodoggone District of British Columbia.

Additional drilling results will be disclosed in batches of successive drill holes as assays become

available.

Phase I Drilling Highlights:

• TDG25-002: 1.02 grams per tonne (“g/t”) gold (“Au”), 2.0 g/t silver (“Ag”), 0.24% copper (“Cu”)

over 164.0 metres (“m”) including 1.73 g/t Au, 2.6 g/t Ag, 0.32% Cu over 67.0 m

• TDG25-003: 1.13 g/t Au, 2.6 g/t Ag, 0.30% Cu over 60.1 m

• TDG25-005: 0.76 g/t Au, 2.0 g/t Ag, 0.23% Cu over 92.9 m

• TDG25-007: 0.84 g/t Au, 1.1 g/t Ag, 0.33% Cu over 64.0 m

Initial Phase I Drill Holes Begin Expanding Aurora West Mineralization

The Company’s previously reported proof of concept Phase I drill hole TDG25-001 (news release Sept

02, 2025) successfully demonstrated that Amarc/Freeport’s AuRORA1 Cu-Au-Ag Zone extends onto

the Company’s tenure. Hole TDG25-001 delivered an impressive intersection grading 1.23 g/t Au, 1.8

g/t Ag, 0.23% Cu over 240.6 m.

Building upon the results from TDG25-001, recently completed 2025 Phase I drill hole TDG-25-002

intersected 1.02 g/t Au, 2.0 g/t Ag, 0.24% Cu over 164.0 m, including a higher -grade sub-interval

averaging 1.73 g/t Au, 2.6 g/t Ag, 0.32% Cu over 67.0 m , demonstrating that the Aurora West

mineralization extends up dip and south of TDG25-001. This new extension begins at a vertical depth

of 175 metres below surface and remains open to further expansion (Figure 1 & 2).

Fletcher Morgan, CEO of TDG remarks, “These initial, widely spaced and broadly mineralized

intercepts of the Phase I program are suggestive of a larger mineralized system than was initially

anticipated. Our success thus far in the 2025 program has warranted the addition of a third drill rig to

hasten the exploration of Aurora West. Given our solid treasury, and fully winterized camp , we are

also contemplating extending the Phase I drilling program through the winter months and into the

2026 exploration season. The longer Program will accelerate our development of this constantly

evolving discovery and may provide year-round news flow.”

Aurora West Outlined Over 450 Metres Down Dip

Additionally, two new intercepts of Cu-Au-Ag mineralization grading 0.76 g/t Au, 2.0 g/t Ag, 0.23% Cu

over 92.9 metres and 0.95 g/t Au, 2.5 g/t Ag, 0.20% Cu over 53. 2 m have been defined by drill hole

TDG25-005, which has also extended the AuWest discovery north and down dip of TDG25 -001

(Figure 2).The two intersections in TDG25-005 are separate monzonite porphyry intrusive dikes.

Further downdip and to the north, at a vertical depth of 440 metres below surface, Phase I drill hole

TDG25-007 extended the Aurora West Zone with multiple intersections: 0.84 g/t Au, 1.1 g/t Ag, 0.33%

Cu over 64.0 m, 0.48 g/t Au, 0.8 g/t Ag, 0.18% Cu over 27.0 m, 0.87 g/t Au, 1.5 g/t Ag, 0.23% Cu over

19.0 m and 0.59 g/t Au, 1.8 g/t Ag, 0.25% Cu over 19.0 metres.

Quality Assurance and Quality Control Protocols

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 b y geologists who inserted certified

reference materials, blanks and duplicates (pulp and coarse) into the sampling sequence at regular

intervals. The 2025 drill core was cut in half (1/2 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 (here).

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 -

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 moder n 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 08, 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% owned and optioned) and mineral claims totaling

over 10,000 hectares including the former producing Hidden Creek copper- gold mine – all located

within the Anyox peninsula at the southern tip of BC’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-funded with the priority exploration focus in 2025 to test for potential extensions of

AuRORA1-style mineralization onto TDG’s 100%-owned GSN project.
