TDG Gold Corp. announced assay results from two more historical drill holes, both of which appear to support the concept that the Baker area of its Toodoggone properties may represent a bulk-tonnage, porphyry-style copper-gold target that was later overprinted by a high-grade epithermal gold-silver system. Historical drill holes BK86-10 and BK87-04 were drilled in 1986 and 1987 respectively, targeting high-grade gold-silver mineralization associated with the Baker B-Vein.

As a result, both holes were only selectively sampled at the time, based on that target model. TDG's relogging and resampling of the full length of these holes has not only confirmed the historical high-grade Au-Ag epithermal-style mineralization, extending this style of mineralization to depth, but has also identified porphyry-style copper-gold veining, alteration and sulphide mineralization comprised of pyrite, chalcopyrite, molybdenite and minor bornite over more than 100 metres of core length starting from near surface and ending in mineralization in both historical drillholes. The broad length weighted average grade intercept for diamond drillhole BK86-10 comprises 0.1 % Cu, 1.07 grams per tonne Au and 4 g/t Ag over 100.26 m from 40.2 m down hole, including 0.2 % Cu and 2.7 g/t Au over 37.4 m from 84.5 m down hole.

Diamond drillhole BK87-04 tested the B-Vein from the northwest to southeast, opposite the dominant drill trend and intercepted the epithermal, Au-Ag overprint at 135.0 m down hole. It also encountered a previously unrecorded 132.4 m interval of Cu-Au porphyry-style mineralization from 14.6 m depth, ending in mineralization at 147.0 m down hole. TDG's 2023 Exploration Program at Baker As reported in July 25, 2023 news release, TDG is approaching Baker as a "back to basics" project with potential to host a bulk tonnage porphyry-style copper-gold deposit that is most likely located deeper than historically drilled holes.

TDG has a relogging, resampling and assaying program underway that aims to use the new information to help identify vectors to potential porphyry targets for drill testing in 2024. TDG has also completed an extensive and intensive stream sediment sampling program across the Baker footprint focused on the potential for a porphyry target. Results are anticipated by early September 2023.

TDG's historical core relogging, resampling and assaying program is low cost and aims to recover and resample as much as possible of the ~30,000 m of diamond drilling known to have been completed in 342 drillholes across the 15 square kilometre ("sq.km") Baker project. The Baker historical core inventory is located at the Baker camp and mill site. So far, TDG has identified 91 complete/nearly complete drillholes for relogging, of which 41 are restacked and ready for logging, 10 have been fully relogged; and 10 have been submitted for assaying and results have been received from 3. During the historical drilling that took place between 1974-2006, only ~15% of the drill core length is estimated to have been assayed for gold-silver and virtually none for any other elements, including copper.

TDG has noted the presence of porphyry-style veining and alteration and the occurrence of bornite (Cu5FeS4), chalcopyrite (CuFeS2) and molybdenite (MoS2) throughout the 10 drillholes logged so far. TDG has also noted a significant increase gold grades in resampled core from hole BK86-10 as compared to historical recorded results for the same hole. Comparable results for BK87-04 are within the historically reported range.

By systematically relogging the historical core, including drill holes where mining is known to have taken place, followed by resampling where appropriate, TDG is aiming to assemble the first comprehensive copper-focused drill database for Baker and to select drill-ready targets for 2024. Alteration/Mineralization: BK87-04 and BK86-10 intersected porphyry style veining, alteration, and mineralization. Volcanic rocks were consistently propylitic and phyllic altered and demonstrated multi-generational stockwork style veining throughout, with pyrite, chalcopyrite, sphalerite and bornite, often associated with or within veins and their selvages and with potassic alteration and flooding.

These drillholes support the structural break observed in BK87-16 where Au-Cu mineralization increases abruptly, with both drillholes ending in weak/moderate Au-Cu mineralization. Based on available relogging and geochemical data acquired to date, the thickness of the east-northeast striking, steeply dipping altered andmineralized zone appears to be a minimum of approximately 120 m and open at depth. Re-assay of the historical intersection of the B-Vein confirmed the Au-Ag grades and widths historically reported.

Both drillholes continued to support the concept that the Baker B-Vein is surrounded by a lower grade halo of Cu-Au mineralization and the Cu mineralization is likely a function of metal scavenging from a larger porphyry system at depth. The modern assay results for drillhole BK86-10 indicate significantly higher grade for Au than the historically recorded grade with an average increase in Au of +52 % over the same 37.4 m interval, and with positive variability of +23 % Au and +75 % Au compared to historically recorded results across two nearly identical higher-grade composites. These differences could be due to a combination of historical effects including sample selection methodology, nugget effect, and/or laboratory methodology particularly for assay results generated by the historical Baker mill laboratory.

The historically published results for drillhole BK87-04 indicate the broader lower grade mineralized halo surrounding the high-grade B-vein system reconciles with modern results; variability is within 0.004 ppm and 0.3 ppm for Au and Ag, respectively. This suggests that historical results are not subject to any bias in methodology and could be validated in the creation of a potential bulk tonnage low grade resource surrounding the historical high-grade Baker vein system.
