TDG GOLD EXTENDS IP ANOMALY ACROSS BOUNDARY FROM AURORA(1) DISCOVERY AND IDENTIFIES A NEARBY NEW GEOPHYSICAL ANOMALY, DRILLING ABOUT TO COMMENCE

TDG Gold Corp. has provided an update on the recently initiated reconnaissance and characterization induced polarization (IP) geophysical survey to the west of Freeport McMoran Inc./Amarc Resources Ltd.'s Aurora gold-rich copper porphyry discovery. Aurora lies immediately adjacent to the company's 100-per-cent-owned Greater Shasta-Newberry (GSN) project in the evolving Toodoggone district of Northern British Columbia.

Highlights:

• IP anomaly (AuWest) identified that is contiguous to and may be indicative of an extension of Freeport-Amarc's Aurora mineralization;
• Phase I drilling program anticipated to begin July 17, 2025, at TDG's AuWest;
• Mapping, soil sampling and other geological studies are under way with the objective of identifying new targets or to better define existing ones;
• TDG is fully financed to conduct an extensive exploration program in 2025.

2025 induced polarization reconnaissance and characterization survey

IP geophysical surveys are known to be an effective technique in identifying disseminated- and stockwork-style sulphides that are often associated with porphyry copper-gold-silver mineralization, manifesting as a chargeability anomaly. The GSN project has never been surveyed with IP methods, and, to date, the data from three wide-spaced lines completed adjacent to and to the west of Aurora have been deemed fit for purpose and utilized for targeting at AuWest, a potential extension to the Aurora mineralization. The first line is located approximately 75 metres from the Freeport-Amarc boundary with 250-metre spacing between the remaining lines. The purpose of this work was to better understand the geophysical signature of the Aurora copper-gold-silver mineralization to test for possible extensions of Aurora onto TDG's mineral tenure and provide a model for drill targeting potential Aurora analogues along the 12-kilometre structural corridor identified on TDG's mineral claims (news release dated March 3, 2025).

A chargeability anomaly in excess of approximately 23 millivolts per volt on strike and apparently contiguous with the Aurora mineralization has been identified near surface and extends to a vertical depth of approximately 350 metres. At surface along the property boundary, the anomaly has a north-south extent of approximately 320 metres and has an apparent plunge to the west. Additional lines are necessary to determine true strike length of the anomaly. This anomaly may represent a potential extension to the Aurora-style mineralization at TDG's AuWest target (news release dated May 7, 2025) and southwest within GSN. Given the nearby Aurora mineralization, this anomaly clearly merits drill testing. Further, a second chargeability anomaly has been identified with a similar signature, exceeding 23 mV/V, underlying the IP anomaly associated with AuWest.

Data from additional infill and reconnaissance IP lines are currently being processed and interpreted. Surveyed areas that generate similar anomalous geophysical responses to that associated with Aurora will be followed up with infill surveys to provide enhanced detail prior to drilling.

Drill mobilized to project site

Drill crews and equipment for a helicopter-supported drill program have begun mobilizing to the project site. Initial drill holes will test for potential mineralized western extensions of the Aurora mineralization, onto TDG's mineral claims, guided by the new geophysical data set. Drilling is expected to begin shortly after July 17, 2025.

About TDG Gold Corp.

TDG is a major mineral tenure holder in the Toodoggone district of northern-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 dated Jan. 25, 2023), which is located directly adjacent to the gold-rich copper porphyry Aurora discovery announced by Freeport McMoran and Amarc Resources (news release dated Jan. 17, 2025).

In 2024, TDG identified new copper-gold target areas over an expanded footprint covering approximately 53 square kilometres known as the Baker complex (news release dated Feb. 28, 2024), including the North Quartz (news release dated April 2, 2024) and Trident (news release dated 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 and 2012, and the historical high-grade gold Mets developed prospect, all of which are road accessible and combined have over 65,000 metres 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 metres 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 dated Jan. 8, 2025), which remains open at depth and along strike.

In July, 2025, TDG closed the acquisition of Anyox Copper Ltd. (news release dated 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 British Columbia's Golden Triangle. Exploration at Anyox will commence in late 2025 and gives TDG a first-mover advantage to a VMS (volcanogenic massive sulphide) horizon within a significant past-producing district with copper-gold-lead-zinc-silver potential.

We seek Safe Harbor.
