TDG Gold Delivers Transformational 2025 and

Advances 2026 Growth Strategy with a Strong Treasury

Vancouver, British Columbia, December 16, 2025 – TDG Gold Corp. (TSXV: TDG | OTCQX: TDGGF)

(the “Company” or “TDG”) is pleased to provide a year-end corporate update highlighting a year of

significant operational, financial, and exploration achievements in 2025, while outlining a focused

and well-funded strategy for continued growth in 2026.

During 2025, TDG delivered a series of transformational milestones that materially advanced the

Company’s scale, asset quality, and market profile. These achievements were driven by the

successful discovery at Aurora West, the strategic acquisition of the Anyox Copper Project, and

disciplined capital deployment across its portfolio of gold and copper assets.

2025 Highlights: Discovery, Scale, and Accretive Growth

2025 marked a defining year for TDG, underscored by a more than 600% year-over-year appreciation

in share price, reflecting growing investor recognition of the Company’s organically driven exploration

success and expanding asset base.

The year was anchored by the Aurora West discovery, where the Company’s inaugural drill hole—

announced in September 2025 (news release Sept 02, 2025)—identified gold-silver-copper (“Au-Ag-

Cu”) mineralization on TDG’s 100% owned tenure that is interpreted to be part of a broader

mineralized system referred to as the Aurora Complex1,2 (Figure 1). The Aurora Complex1,2 refers to a

geological interpretation of a broader mineralized system encompassing Freeport-Amarc’s AuRORA2

discovery and TDG’s Aurora West discovery, based on available geological and drilling information.

Phase I drilling rapidly outlined over 600 metres (“m”) of continuous, high-tenor gold-copper

mineralization, with the system remaining open in multiple directions. These results highlight the

early-stage nature and significant upside potential of the Aurora Complex1,2.

In June 2025, TDG completed the amalgamation with Anyox Copper Ltd., concurrent with a C$28.75

million bought-deal financing, significantly strengthening the Company’s balance sheet and

portfolio. The acquisition of the Anyox Project provides shareholders with exposure to a historically

high-grade, past-producing copper district that has seen limited modern exploration since

operations ceased in 1936, representing a compelling opportunity for new discovery.

Operationally, TDG executed an aggressive exploration campaign during the second half of 2025,

with up to five drill rigs operating concurrently across Aurora West and Anyox. The Company expects

to enter 2026 with a treasury exceeding C$20 million, providing flexibility to advance multiple high-

impact programs without near-term dilution.

Aurora West: Proof of Concept and Platform for Expansion

The 2025 Phase I drill program at Aurora West delivered a rapid proof-of-concept, confirming a

meaningful extension of the AuRORA 2 Au-Ag-Cu mineralized system onto TDG’s ground through an

accelerated and capital-e Ưicient exploration approach. To date, drilling by TDG has outlined an

approximately 600 m long extension of the Aurora Complex 1,2 immediately adjacent to the property

boundary. This milestone was achieved with 22 drill holes totalling ~14,400 metres, of which 9 holes

have been publicly disclosed to date.

Recently reported drilling at the Aurora Complex1,2 by the Freeport–AMARC joint venture has outlined

a significant northward extension approaching the Company’s property boundary. Of particular

importance, drill hole JP251092 returned an exceptional intercept of 1.38 grams per tonne (“g/t”) Au,

0.27% Cu, and 1.6 g/t Ag over 201.0 m e. This intersection lies just 200 m south of the Company’s

tenure, highlighting a compelling, untested expansion target with strong discovery potential ( Figure

2).

Remaining analytical results are expected to be released in batches throughout early Q1 2026,

providing a steady flow of news and additional insight into the scale and continuity of mineralization.

Figure 1 presents the Phase I drilling progress. Drilling is currently paused for the Holiday Season and

is expected to resume in January.

Shasta - Strategic Growth Plan For 2026

With Phase I drilling at Aurora West transitioning to a planned winter shutdown, drilling is scheduled

to resume in January 2026, with lower-elevation work prioritized through the first half of the year due

to seasonal and safety considerations.

During this period, TDG will accelerate growth at Shasta ( Figure 3 ), a key component of the

Company’s development strategy and a near-term, capital-eƯicient opportunity to expand resources

within the Greater Shasta-Newberry (“GSN”) Project. The GSN area hosts numerous untested near-

surface targets within an established epithermal Au-Ag system located approximately one kilometre

(“km”) west of the Aurora Complex1,2.

The Shasta Deposit currently hosts a pit-constrained Mineral Resource Estimate 5 (“MRE”)

comprising Indicated resources of 515.8 thousand ounces (“koz”) gold equivalent (“AuEq”) at an

average grade of 1.35 g/t AuEq and Inferred resources of 505.5 koz AuEq at an average grade of 1.04

g/t AuEq, reported at a 0.40 g/t AuEq cut-oƯ grade and to a maximum depth of approximately 140 m

(with grades for individual metals disclosed in the supporting tables of the Company’s January 8,

2025 news release).

Anyox Project: Unlocking an Historic Copper District with Modern Technology

At Anyox, 2025 work focused on the Hidden Creek Mine, the cornerstone of the Project and a past-

producing, high-grade copper operation that produced from 1914 to 1935. Mining ceased during the

Great Depression due to economic conditions rather than depletion of mineralization3.

In Q3 2025, TDG completed a next-generation, deep-penetrating surface geophysical survey,

marking the first modern subsurface deep investigation below the historical mine workings. The

survey identified new, highly conductive anomalies at depth within the Hidden Creek footprint.

To refine these targets, TDG utilized two drill rigs in Q4 2025 to extend three drill holes from the 2024

program, repurposing them as downhole geophysical platforms. This work significantly improved

resolution and resulted in the identification of additional targets, most notably below the lowest

historical mine levels—an area that has never been drill tested.

Drilling of these high-priority targets is scheduled to commence in January 2026, with an initial,

results-driven program of approximately 3,000 m designed to test the potential for a new copper

discovery beneath the historic mine.

Positioned for a Catalyst-Rich 2026

With multiple discoveries underway, two district-scale projects advancing in parallel, and a strong

treasury, TDG enters 2026 positioned for sustained, exploration-led value creation. The Company’s

strategy remains focused on disciplined capital deployment, systematic exploration, and unlocking

the full potential of its gold and copper focused portfolio.

About TDG Gold Corp.

TDG is a major mineral tenure holder in the Toodoggone District of north-central British Columbia,

Canada, with 100% ownership of ~50,000 hectares of brownfield and greenfield exploration ground.

In 2023, TDG defined the 5.5 sq.km Greater Shasta-Newberry exploration target area (news release

Jan 25, 2023 ) which is located directly adjacent to the recent gold-rich copper porphyry AuRORA 1

discovery announced by Freeport McMoran Inc. and Amarc Resources Ltd. (news release Jan 17,

2025).

In 2024, TDG also identified new copper-gold target areas over an expanded footprint covering ~53

sq.km known as the ‘Baker Complex’ (news release Feb 28, 2024), including the North Quartz (news

release Apr 02, 2024) and Trident (news release Mar 07, 2024) copper-gold porphyry 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-

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 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.
