Ongoing Expansion Drilling Continues to Demonstrate Continuity of Both Scale and Tenor

Article content

Having intersected 1.25 g/t Au, 2.2 g/t Ag, 0.33% Cu over 128.7 metres, Phase I 2025 drill hole TDG25-013 has extended the Aurora West Zone Au-Ag-Cu mineralization southerly along the property boundary (Figures 1 & 2).

Article content

This new interval has suggested the tenor and thickness of the Aurora West Zone mineralization continues an additional 100 m south of previously reported drill hole TDG25-010 which intersected 1.02 Au, 2.0 g/t Ag, 0.24% Cu over 164.0 m including 1.54 g/t Au, 2.6 g/t Ag, 0.36% Cu over 56.0 m (news release Nov 26, 2025).

Visual Aurora Style Mineralization Encountered in Step Out Drilling

Article content

Mineralization visually identified as pyrite and chalcopyrite, consistent with that observed throughout the 2025 Aurora West drilling program, has been intersected in 2025 drill hole TDG25-020. Visual sulphide mineralization occurs from approximately 710 m to approximately 820 m down hole. Rushed analytical results are pending.

Article content

Drill hole TDG25-020 represents a ~500-m north-northwest step-out from the currently defined Aurora West mineralization. While the rock types, alteration assemblages, sulphide species, and are visually similar to those observed within the Aurora West Zone, there is no assurance that the Au-Cu-Ag concentrations returned by analytical results will be comparable to those reported elsewhere within the Aurora Complex.

2026 Winter Drilling Program Mobilization on Schedule

Article content

Drilling at the GSN Project in 2026 will initially focus on completing the drill holes that were paused for the December 2025 scheduled shutdown. Further drill holes in Aurora West Zone will be results driven. Once completed, drilling will subsequently focus on: (1) potential extensions to the Aurora West Zone, (2) testing the scale potential of the larger and yet unexplored Aurora Complex¹ and (3) testing for potential extensions to the near surface, pit constrained Mineral Resource Estimate⁴ in the vicinity of the epithermal Shasta complex.

Quality Assurance and Quality Control Protocols

Article content

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 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).

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 underway 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 analyzed in the batch with the failed QA/QC sample are re-analyzed.

² Preliminary Assay Results: The data reported herein are considered preliminary, as the full set of assay results for the 2025 program has not yet been received. While the Company’s QA/QC protocols (including the insertion of blanks, CRMs, and duplicates) have been applied, the current dataset is not sufficient to fully assess laboratory performance across the entire program. As additional assay results are returned and incorporated, the Company will provide an updated assessment of QA/QC performance to ensure data integrity and reliability.

³Aurora/Aurora West Zone Mineralization Isoshell: The isoshell is calculated using data derived from length weighted composites from TDG (news releases Sept 02, Oct 15 and this release) and Amarc Resources^a,b,c,d,e,f utilizing a 0.3 g/t Au cut-off grade to generate an implicit model using radial basis function (“RBF”) interpolation methodology. This creates a very smooth, highly localised 3D interpretive model that is controlled by nearby data and has limited influence at long distance. This model does not account for geological constraints.

⁴Mineral Resource Estimate (MRE): All scientific and technical information relating to the TDG’s Shasta Project pertaining to the Shasta Mineral Resource Estimate (“Shasta MRE”) contained in this presentation is derived from the Technical Report dated February 21st, 2025 (with an effective date of December 29, 2024) titled “2025 Updated Resource Estimate For The Shasta Deposit” (the “2025 Technical Report”) prepared by Sue Bird, MSc., P.Eng. of Moose Mountain Technical Services. Mineral Resources are reported at a 0.40 g/t AuEq cut-off. AuEq is calculated using US$1,750/oz Au, US$21/oz Ag, and metallurgical recoveries of 93% Au and 85% Ag, using the formula: AuEq (g/t) = Au (g/t) + (Ag (g/t) × 0.0123) The information contained herein in respect of the Shasta MRE is subject to all of the assumptions, qualifications and procedures set out in the 2025 Technical Report and reference should be made to the full text of the 2025 Technical Report, a copy of which has been filed with the securities regulators in each of the provinces of Canada (except Québec) and is available on www.sedar.com.

About TDG Gold Corp.

Article content

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.

Article content

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 Aurora¹ discovery announced by Freeport McMoran Inc. and Amarc Resources Ltd. (news release Jan 17, 2025). TDG has demonstrated the extension of Aurora-style mineralization onto TDG’s mineral claims at Aurora West with multiple drill assays published or pending, and drilling ongoing.

Article content

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.

Article content

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.

Article content

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.

Article content

TDG is well-funded with the priority exploration focus in 2026 to continue to test for potential extensions of Aurora¹-style mineralization within TDG’s 100%-owned GSN project.
