TDG Gold drills 16.4 g/t Au over 8.3 m at Toodoggone

Mr. Steven Kramar reports

TDG GOLD INTERSECTS 8.3 M OF 16.4 G/T GOLD FROM 51 METRES DEPTH AT METS, TOODOGGONE

TDG Gold Corp. has intersected further high-grade, near-surface gold (Au) mineralization in the final diamond drill hole completed in the 2023 exploration program at TDG's 100-per-cent-owned Mets mining lease, located in the Toodoggone district of north-central British Columbia.

Diamond drill hole MT23-005 (HQ, oriented) was completed in the Mets A-Zone (1) and intersected:

  • 16.36 grams per tonne Au, four g/t silver (Ag) over 8.3 metres (m) from 50.5 m downhole depth using a cut-off grade (COG) of 3.00 g/t Au.

As stated previously (news release Nov. 28, 2023), the high-grade Au mineralization at Mets appears to track a distinct very-low-frequency-electromagnetic (VLF EM) conductivity gradient coincident with a magnetic susceptibility low. This observation is consistent throughout the 50 m of strike between drill holes MT23-004 and MT23-005/003. Further evaluation is under way to apply this interpretation across the known 130 m of strike-length of the A-Zone (1), to generate targets for the potential southern (1) and northern (1) extensions of the A-Zone and, ultimately, explore across the entire mining lease. MT23-005 was designed as a geological test of the potential controls on the northern extent of the A-Zone. The high-grade gold mineralization intersected extends the high-grade mineralized zone above hole MT23-003. Due to a mechanical issue with the drill rig, the drill hole was stopped at 74 m downhole depth rather than the targeted 210 m and hence failed to test the northern controls at depth.

Steven Kramar, TDG's vice-president, exploration, commented: "The five diamond drill holes completed at Mets in 2023 validate the continuity of shallow, high-grade gold mineralization within the A-Zone. In combination with TDG's high-resolution geophysics completed across the Mets mining lease, along with the recompiled historical information, we are developing a targeting framework and look forward to refining targets, starting with the potential extensions to the north and south of the A-Zone."

Mineralization encountered

Drill hole MT23-005 is interpreted to have intersected the same quartz-barite breccia style of mineralization as MT23-001 (news release Sept. 7, 2023) and MT23-002/MT23-003 (news release Sept. 11, 2023) and MT23-004 (news release Nov. 28, 2023). This limited drill program validates the continuity of the high-grade historical drilling and demonstrates potential to expand on the high-grade A-Zone.

MT23-005

The final drill hole of the 2023 Mets drill campaign was designed to collect structural geological data by drilling oblique to previous drilling and examine the potential for high-grade mineralization on the other side of the previously untested N75 fault, as well as testing for potential additional structures. MT23-005 intersected high-grade Au in the vicinity of the intersection reported from MT23-003 (news release Sept. 11, 2023) and may expand the previously interpreted high-grade zone. The drill hole was terminated early at a shallow depth (74 m), well before reaching the N75 fault and its target depth of 210 m due to mechanical issues on the drilling rig. The casing was left in the drill hole so that TDG can re-enter the hole and complete drilling in the future. Historical (2) trenching in the vicinity of MT23-005/003 reported results ranging from 0.04 to 15.0 grams per tonne gold in one m composite chip sampling over 48 m of the trench-length sampled.

Assay results were received from MSA Labs Canada (MSA). Samples reported in this news release with Au concentrations greater than 20 g/t were subject to subsequent metallic screen analysis for individual samples reporting greater than 20 g/t Au. Results reported are considered final.

Magnetics/VLF-EM results interpretation

The same parameters were utilized to process the VLF as for drill hole MT23-004 (news release Nov. 28, 2023) using the Karous and Hjelt (KH) filter to qualitatively interpret the 28.4 kilohertz signal produced by the ground-based geophysics survey performed in 2023. The three-dimensional interpolated voxel model supports the initial interpretation of coincident VLF conductivity gradient tracing the high-grade mineralization in the Mets A-Zone also supported by a magnetic susceptibility low tracking the same feature. This feature has only been drill tested historically to shallow depths (around 60 m) and remains open at depth where it exhibits increasing current density. While these geophysical features are seemingly coincident, it also could be due to other geological factors.

Short wave infrared light interpretation

Short wave infrared light (SWIR) analysis was undertaken on all the core drilled at Mets in 2023. SWIR is a helpful tool to identify and characterize minerals and establish relationships between species of minerals and alteration/mineralization. Preliminary analysis suggests a relationship between the presence or absence of interpreted dickite, the high-grade Au mineralization and the coincident geophysics response. Dickite is a clay mineral (part of the kaolinite group) and can be often found associated with gold-bearing epithermal systems. The SWIR interpretation appears to be strongly associated with the upper portions of the high-grade Au mineralization in all five holes drilled at Mets in 2023. Further interpretations are currently under way to fully characterize alteration. SWIR responses can be non-unique, and X-ray diffraction analysis is required to confirm mineral species present.

Quality assurance/quality control

Samples for the Mets 2023 drill program were handled via rigorous chain of custody, including sample collection, processing and delivery to the MSA laboratory in Langley, B.C. The drill core was logged, photographed and sampled at TDG's Baker mine site and processed by geologists and technicians. Quality assurance and control (QAQC) materials were inserted into the sampling sequence during geological sample selection. The drill core selected for sampling was split by mechanical core splitter and then placed in zip-tied polyurethane bags, then in security-sealed rice bags before being delivered directly by TDG staff from the Baker mine site, to Bandstra Transportation Systems in Prince George, ultimately to the MSA facility in Langley, B.C. Samples were prepared and analyzed following procedures: CRU-240, SPL-415, PPU-510 for sample preparation, FAS-221 for Au and IMS-235 for Ag and trace elements. Overlimit concentrations (greater than 20 parts per million gold) of precious metals were analyzed (where applicable) by MSC-550. Information about methodology can be found on the MSA Labs website, in the analytical guide.

QAQC is maintained internally at the lab through rigorous use of internal certified reference materials (CRMs), blanks and duplicates. An additional QAQC program was administered by TDG through the verification of lab results via use of CRMs and blank (unmineralized) samples that were blindly inserted into the sample batch. If a QAQC sample returns an unacceptable value an investigation into the results is triggered and when deemed necessary, the samples that were tested in the batch with the failed QAQC sample are retested.

The Drill hole collar information table presents the particulars for the drill holes in this news release. During the sampling process, HQ drill core was split in half using a mechanical core splitter. The collar location was located using Global Positioning System (GPS) Real Time Kinematics (RTK) system with high precision.

The degree of risk increases substantially where an issuer's properties are in the mineral exploration stage as opposed to the development or operational stage. Exploration targets and/or exploration zones and/or exploration areas are speculative and there is no certainty that any future work or evaluation will lead to the definition of a mineral resource.

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 earn-in agreement. 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 m 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 m 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 news release 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 news release Jan. 25, 2023). In 2023, TDG published the first modern drill results from the Mets mining lease (see TDG news releases Sept. 7, 2023, Sept. 11, 2023, and Nov. 28, 2023).
