TDG GOLD IDENTIFIES NEW COPPER-GOLD PORPHYRY TARGET IN SAUNDERS AREA, BAKER COMPLEX

TDG Gold Corp. has provided an update from continuing targeting work within TDG's approximately 42-square-kilometre Baker complex. TDG has identified a greater-than-five-square-kilometre target within Saunders area of the Baker complex, displaying the geological features and physiography that suggest potential to host an intrusive-related copper-gold-molybdenum porphyry. This new target (designated Trident) is at least five square kilometres, is open to the northwest and southeast, and has never been drill tested.

The new Saunders area is located approximately five kilometres from TDG's Baker mill and road access is as close as the Black Gossan target near the new target's western boundary.

Prior exploration work

Historical exploration work over Saunders included limited surficial mapping, geochemical sampling (silts, soils and rocks) and geophysics, including ZTEM (Z-tipper electromagnetics). In 2023, TDG completed a lithic drainage sampling (LDS) survey covering the Baker complex and Greater Shasta-Newberry. The Saunders area had amongst the strongest values for copper/gold/molybdenum over an approximately five-kilometre drainage area as well as highly anomalous concentrations of other elements, including lead, zinc and pathfinder elements, including tellurium (see news release dated Feb. 28, 2024).

Geological interpretation

TDG has completed the compilation of the existing information for the new Trident target. Data suggest the presence of an interpreted causative intrusion, appearing as a buried, dome-like high-resistivity feature covered with blanket-like zone of lower resistivity. The low resistivity feature is interpreted to be a zone of higher sulphide content associated with the phyllic (quartz/sericite/pyrite) altered cupola of the intrusion at or near a major regional unconformity between the Toodoggone formation (above) and the Takla group rocks (below). Economic metal concentrations in British Columbia style porphyries are typically located adjacent to regional-scale unconformities. For example, the KSM and Brucejack deposits are situated at the so-called Kyba-Nelson Red Line, which represents the unconformity between the Stuhini and Hazelton groups of rocks in the Golden Triangle.

Steven Kramar, TDG's vice-president, exploration, commented: "Historical exploration was very limited outside of the Baker mine footprint and its immediate vicinity. Our new Trident target within the Saunders area has never been drill tested and represents a compelling, copper-gold-molybdenum porphyry opportunity located within the [approximately 42-square-kilometre] Baker complex and that's also within five kilometres of our existing infrastructure."

Saunders geological summary

The Saunders area within the Baker complex comprises several historical prospects, with limited past exploration focused on epithermal gold and silver. There has been little follow-up and no drilling despite widespread, coincident geophysical and base metal/precious metal geochemical anomalies consistent with the possible presence of a poorly exposed to shallowly buried large porphyry system.

The Saunders area lies at the intersection of several regional-scale structural zones and coincides with very strong airborne electromagnetic and magnetic anomalies typically associated with intrusions in this part of the Toodoggone belt. Alteration observed by past operators included high-aluminous/high-sulphidation assemblages, with minerals such as pyrophyllite, alunite, diaspore and clays in large gossans as well as multiple exposures of dikes and small stock-like bodies exhibiting porphyry-style alteration and copper-plus-molybdenum mineralization. Widespread gold-silver mineralization is well documented in the target area. These mineral assemblages are often located at the tops of porphyry systems. TDG's 2022 airborne hyperspectral survey confirmed the presence of these assemblages and expanded the known footprint of these assemblage over a broad area coincident with the catchments and headwaters of the highly anomalous LDS stream sediment sample sites (see news release dated Feb. 28, 2024).

Much of the higher-elevation areas within the target footprint are overlain by interpreted postmineralization volcanic rocks. However, the results of the high-density LDS survey sampling smaller catchments above and below the postmineral volcanic cover contacts were effective in outlining prospective target areas in the underlying package.

About TDG Gold Corp.

TDG is a major mineral tenure holder in the historical Toodoggone production corridor of north-central British Columbia, Canada, with over 23,000 hectares of brownfield and greenfield exploration opportunities under direct ownership or under acquisition. TDG's flagship projects are the former-producing, high-grade gold-silver Shasta and 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. The 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 May, 2023, TDG published an updated mineral resource estimate for Shasta (see TDG's news release dated May 1, 2023), which remains open at depth and along strike. In January, 2023, TDG defined a larger exploration target area adjacent to Shasta (Greater Shasta-Newberry; see TDG's news release dated Jan. 25, 2023). In 2023, TDG published the first modern drill results from the Mets mining lease (see TDG's news releases dated Sept. 7, 2023, Sept. 11, 2023, and Nov. 28, 2023).
