TDG Gold Intersects 8.3 M of 16.4 g/t Gold from 51 Metres Depth at Mets, Toodoggone

WHITE ROCK, BC / ACCESSWIRE / December 4, 2023 / TDG Gold Corp (TSXV:TDG) (the "Company" or "TDG") is pleased to report further high-grade, near-surface gold ("Au") mineralization intersected in the final diamond drillhole completed in the 2023 exploration program at TDG's 100 % owned Mets mining lease, located in the Toodoggone District of north-central B.C.

Diamond drillhole MT23-005 (HQ, oriented) was completed in the Mets A-Zone¹ and intersected:

• 16.36 grams per tonne ("g/t") Au, 4 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 (Table 1).

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 (Figure 1) coincident with a magnetic susceptibility low (Figure 3). This observation is consistent throughout the 50 m of strike between drillholes MT23-004 and MT23-005/003 (Figure 2). Further evaluation is underway to apply this interpretation across the known 130 m of strike-length of the A-Zone¹, to generate targets for the potential southern¹ and northern¹ extensions of the A-Zone¹ 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 drillhole 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 VP Exploration, commented: "The five diamond drillholes 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-Zone¹."

Mineralization Encountered

Drillhole MT23-005 is interpreted to have intersected the same quartz-barite breccia style of mineralization as MT23-001 (news release Sept 07, 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 drillhole 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 (Image 1) 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 drillhole 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 drillhole so that TDG can re-enter the hole and complete drilling in the future. Historical² trenching in the vicinity of MT23-005/003 (Figure 1) reported results ranging from 0.04 - 15.0 g/t Au in 1 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 > 20 g/t were subject to subsequent metallic screen analysis for individual samples reporting > 20 g/t Au. Results reported are considered final.

Magnetics / VLF-EM Results Interpretation

The same parameters were utilized to process the VLF (Figure 1) as for drillhole MT23-004 (news release Nov 28, 2023) using the Karous and Hjelt ("KH") filter to qualitatively interpret the 28.4 kHz 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 (the "Feature") tracing the high-grade mineralization in the Mets A-Zone¹ also supported by a magnetic susceptibility low (Figure 3) tracking the same Feature. This Feature has only been drill tested historically to shallow depths (~ 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 ("SWIR") 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 (Figure 4) 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 5 holes drilled at Mets in 2023. Further interpretations are currently underway to fully characterize alteration. SWIR responses can be non-unique, and X-Ray Diffraction ("XRD") analysis is required to confirm mineral species present.

QA/QC

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 drillcore 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 drillcore 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 (> 20 ppm Au) 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 (here).

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 re-tested.

Table 2 presents the particulars for the drillholes in this news release. During the sampling process, HQ drillcore 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.

¹Mineral Exploration/Exploration Target Area(s): TDG is a mineral exploration focused company and the Company's Projects are in the mineral exploration stage only. 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.

²Historical Data: This news release includes historical information that has been reviewed by TDG's qualified person (QP). TDG's review of the historical records and information reasonably substantiate the validity of the information presented in this news release; however, TDG cannot directly verify the accuracy of the historical data, including (but not limited to) the procedures used for sample collection and analysis. Therefore, any conclusions or interpretations borne from use of this data should be considered too speculative to suggest that additional exploration will result in mineral resource delineation. TDG encourages readers to exercise appropriate caution when evaluating these data and/or results.

³Historical Drillcore Sampling & Assay Methodology: Historical drillcore was geologically logged with lithologies identified and notable geological features recorded. Historical drillcore was split in half (and in rare cases sawn in half) along sample intervals (lithology and mineralization dependant) generally less than 3 m. Chemical analysis was performed dominantly for precious metal analysis (Au and Ag), and infrequently for base metals (Pb, Zn, Cu), and rarely for major elements and trace elements. Historically, different commercial laboratories were utilized in addition to an assay lab at Baker Mine Site. These lab facilities may or may not have had accreditation and in all cases accreditation (if applicable) pre-dated current ISO standards. Over that period, a variety of digestion and assay methods were used, including atomic absorption, fire assay atomic absorption, aqua regia atomic absorption and aqua regia ICP with varying detection limits. Reference materials (if any) were inserted at the analytical level and thus were unblind to the facility processing the samples.

⁴Unassayed Historical Drill Core: Historical drill core intersections, lengths or intervals referenced for re-assay or geological analysis may not be available or suitable for sampling. Historical drill cores were inherited with the project and TDG provides no guarantees or warranties that these drill cores are part of the historical inventory, are available and/or have not degraded to a state that would render them wholly unusable for the purposes of scientific investigation. TDG provides no warranties/guarantees that these historical un-assayed drill cores host precious or base metal mineralization.
