Including 21.3 g/t Au over 7 m from 24 m downhole
WHITE ROCK, BC / ACCESSWIRE / September 7, 2023 / TDG Gold Corp (TSXV:TDG) (the "Company" or "TDG") is pleased to report high-grade, near-surface gold ("Au") mineralization intercepted in the first diamond drillhole at TDG's 100% owned Mets mining lease located in the Toodoggone District of north-central B.C.
Diamond drillhole (HQ, Oriented) MT23-001 was completed in the Mets A-Zone1 and intercepted:
11.1 grams per tonne ("g/t") Au, 1 g/t silver ("Ag") over 20.0 metres ("m") from 19.0 m downhole depth; and
including 21.3 g/t Au, 1 g/t Ag over 7.0 m from 24.0 m downhole depth (Image 1 & Table 1).
Assay results were received from MSA Labs Canada ("MSA"). Results are considered preliminary with the necessity to run metallic screen analysis for individual samples reporting > 20 g/t Au. Final results will be reported in due course. Fine visible gold was noted in the discharge from the cutting saw and hence core was split with a core splitter to minimize gold losses. Results from additional drillholes completed at Mets are pending.
Fletcher Morgan, TDG's CEO, commented: "These are the first drill results from the Mets A-Zone1 since exploration and development ceased in 19922. The interpreted structural zone appears to extend over 1 km of strike length and received minimal drilling outside of the 130 m strike length of the Mets A-Zone. Our technical team is continuing to track the mineralizing structure along strike and to generate drill targets to fully evaluate the potential of the mineralizing system across the entire Mets mining lease."
Mets Mining Lease
TDG's Mets mining lease is a gold-rich 200-hectare developed prospect1 with 8,784 m of historical diamond drilling2,3 and 2,622 m of trenching2 which took place between 1985-1990, and ~350 m of underground development2 completed in 1991-1992. Development work ceased in late 1992, before production commenced. Mets is road accessible and located ~23 kilometres ("km") northwest of TDG's former producing Baker mine, mill and tailings storage facilities (Figure 1). In October 2022, TDG received a 30-year extension to the Mets mining lease through to April 2053. In November 2022, TDG received the complete archive of historical work completed at Mets, including laboratory assay certificates2,3. In December 2022, TDG published a high-grade underground Exploration Target Range ("ETR") for Mets (see December 21, 2022) based on TDG's recompilation of the available historical information2,3.

* Results are PRELIMINARY. Subsequent laboratory analysis and detailed QA/QC is underway.
**Intervals are core-length weighted. True width is estimated between 80-90 % of core length; core recovery is estimated to be on average > 80 %, whereas core recovery is an average of > 95 % through the mineralized composites stated in the Table.
***Composite results were built using 3.0 g/t Au cut-off, although there may be intervals within the composite below 3.0 g/t Au.
****Calculated composites are truncated to significant 2 decimal places for Au and the nearest integer for Ag.
*****Calculated composites may not sum due to rounding.

2023 Mets Drilling
Mets is classified as a "developed prospect1" having previously had a historical mineral resource and reserve4 estimate and ~350 m of underground development in the A-Zone1 completed in 1992. The A-Zone1 is defined over ~130 m of strike length with a high density of historical drilling2,3 (the locus of the underground development). The hole reported in this news release was drilled within the Mets A-Zone1 to confirm the 1980s drilling2,3 results and modern drill results from additional holes completed at Mets are pending.
Steven Kramar, TDG's VP Exploration, commented: "Diamond drillhole MT23-001 is a near neighbour to multiple reported historical drillholes within the A-Zone1 at Mets. The results are as expected, confirming the presence of high-grade gold mineralization within the A-Zone1 and validating our model of the underground development known to have taken place. Our 2023 drill program was also designed to enhance our understanding of the structural controls to the high-grade mineralization and enable more accurate targeting of the known and potential extensions to mineralization. Our next step is to deploy a ground based magnetic and very low frequency geophysical survey to delineate the Mets structure over the entire mining lease in anticipation of a larger drill program in 2024."
The Mets mining lease is underlain by a succession of subaerial volcanic and volcaniclastic rocks, stratigraphically termed the "Toodoggone Formation" comprising andesitic or dacitic compositions and associated epiclastic rocks. The Mets structure is a quartz-barite breccia that appears to track the geological contact between tuffaceous dacite (hanging wall) and potassium feldspar porphyritic andesite (footwall). Mineralization associated with the breccia is historically described as Au dominant, Ag subordinate (i.e., high Au/Ag ratio) occurring as free gold along margins of quartz and/or barite grains with trace amounts of electrum, argentite and/or tetrahedrite.
Drillhole MT23-001 intercepted the volcanic sequence as predicted by TDG's geological modelling and intersected the quartz-barite breccia (Image 2) at the contact between the dacitic and andesitic volcanic rocks at the expected depth. The mineralized hydrothermal breccia is described as angular dacite clasts supported in a coarse-grained subhedral quartz and bladed barite crystal matrix, with trace visible very fine-grained sulfides (pyrite and galena) present in quartz-barite veining, on vein selvages and in vugs. Alteration can be described as argillic/silicic proximal to the Mets structure. Structural analysis of the Mets drill data is underway.

Samples for the Mets 2023 drill program were handled via rigorous chain of custody, between 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 was selected for sampling and 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 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-230 for Ag and trace elements. Overlimit concentrations (> 20 ppm Au) of precious metals will be 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 drillhole particulars for the drillhole 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.

The technical content of this news release has been reviewed and approved Steven Kramar, MSc., P.Geo., Vice President, Exploration for TDG Gold Corp., a qualified person as defined by National Instrument 43-101.
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.
4Historical Mineral Resource/Reserve: TDG has not reported the historical mineral resource/reserve estimates prepared by prior owners as the confidence in the estimates is insufficient to allow meaningful application of technical and economic parameters to support an assessment of reasonable prospects for economic extraction as required for public disclosure. There is no assurance that historical mineral reserves/resources will be converted into mineral resources/reserves prepared in accordance with the requirements of NI43-101. Historical mineral reserves/resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral resources/reserves in accordance with NI43-101, however, it is reasonably expected that the majority of the historical mineral reserves/resources could be upgraded 43-101 compliant resources with continued exploration.
