TDG Gold Corp. (TSXV: TDG; OTCQX: TDGGF) has mobilized a second drill rig to its 100%-owned Greater Shasta-Newberry (GSN) exploration project in northern British Columbia’s Toodoggone District. The move is part of an accelerated, fully funded exploration initiative targeting potential copper-gold-silver mineralization, as the company advances its 2025 Phase I drilling program.

The GSN project is located immediately adjacent to the AuRORA1 discovery, a copper-gold porphyry system announced in 2024 by Freeport McMoRan Inc. and Amarc Resources Ltd. While TDG has no ownership in AuRORA1 or related adjacent properties, the proximity has shaped exploration strategies at GSN, particularly around TDG’s AuWEST target area, which lies directly west of the Freeport-Amarc discovery.

Additional Drill Rig Deployed

The newly mobilized second drill rig will focus on rapidly testing new exploration targets generated through an integrated analysis of geophysical, geochemical, and geological data. This includes results from the 2025 Induced Polarization (IP) surveys currently being conducted.

According to TDG, the targets have been identified by overlaying multiple datasets, including IP responses, alteration mapping, structural data, and regional magnetic anomalies. Both drill rigs are now operating in the AuWEST area. Drilling locations will remain flexible and data-driven, based on ongoing interpretations of geological and geophysical findings.

The second drill rig is scheduled to begin operations by the end of this week.

Current Drilling Activity and Early Results

So far, one near-vertical drill hole has been completed, reaching a depth of 645 metres. This hole was designed to assess whether mineralization related to the AuRORA1 system extends onto TDG’s GSN property. Additionally, it targeted a gold-in-soil geochemical anomaly that aligns with IP anomalies in the same area.

The drill core from the initial hole has been sent for expedited assay analysis. TDG stated that results will be released once appropriate evaluations have been completed. No specific timeline has been provided for when assay results will be made public.

Phase I Drilling and Geophysical Analysis

The 2025 Phase I exploration program is supported by geophysical data from the ongoing IP survey, as well as previous airborne and ground magnetic surveys. TDG reports that the geophysical data has outlined both upper and lower anomalies, some of which appear to share characteristics with the AuRORA1 copper-gold-silver discovery.

Of particular interest is the upper anomaly, which occurs at a similar elevation to AuRORA1. Drill spacing has been planned at approximately 100 metres between holes to help delineate the scale and continuity of any mineralization. However, TDG notes that these intervals could be adjusted based on geological interpretations from early drilling.

Context: GSN and the Evolving Toodoggone District

TDG Gold is a significant mineral tenure holder in the Toodoggone District, controlling approximately 50,000 hectares of both brownfield and greenfield terrain. The GSN project, covering roughly 5.5 square kilometres, was first outlined as a major exploration target in January 2023.

GSN gained additional exploration interest following the January 2025 announcement of the nearby AuRORA1 discovery by Freeport and Amarc. While TDG has clarified that it holds no interest in the adjacent discovery, the presence of significant mineralization nearby has influenced its exploration focus.

In 2024, TDG expanded its exploration footprint within the region by identifying new copper-gold targets across an area referred to as the “Baker Complex.” The Baker Complex, spanning approximately 53 square kilometres, includes the North Quartz and Trident targets, both announced in the first half of 2024.

In addition to GSN, TDG’s portfolio in the Toodoggone includes several historical mining operations such as the Shasta and Baker mines, which produced intermittently between 1981 and 2012. Combined, these sites have more than 65,000 metres of historical drilling data. The company has updated the mineral resource estimate for Shasta in 2025, noting the deposit remains open at depth and along strike.

Expansion into Anyox District

In July 2025, TDG completed the acquisition of Anyox Copper Ltd., adding over 10,000 hectares of mineral tenure on British Columbia’s Anyox Peninsula, part of the southern end of the Golden Triangle. The acquisition includes the former producing Hidden Creek copper-gold mine and gives TDG access to a volcanogenic massive sulphide (VMS) system with copper, gold, lead, zinc, and silver potential.

Exploration at Anyox is expected to commence in the second half of 2025. The area is considered historically significant due to past production but has seen limited modern exploration.
