White Rock, British Columbia, April 12, 2022. TDG Gold Corp. (TSXV: TDG) (the “Company” or “TDG”) is pleased to report preliminary results from five drillholes from its 2021 Shasta diamond drill program including 21.0 metres (“m”) of 0.92 grams per tonne (“g/t”) gold (“Au”) and 44 g/t silver (“Ag”) [1.47 g/t AuEq*] from 48.0 m depth in hole SH21-035; 36.0 m of 0.92 g/t Au and 20 g/t Ag [1.17 g/t AuEq*] from 77.0 m depth in SH21-041; and, 16.0 m of 1.26 g/t Au and 46 g/t Ag [1.84 g/t AuEq*] from 51.5 m depth in hole SH21-044. All results contained within this news release are from holes drilled within the Creek Zone at TDG’s former producing Shasta project in the Toodoggone District, B.C. (Figure 1).
Key intercepts for diamond drillholes SH21-035, SH21-041, SH21-044, SH21-046 and SH21-049 are presented in Table 1 and shown in cross-sections (Figures 2-3). Drill results for remaining 2021 drillholes are pending analytical results.
Table 1. Results from the 2021 Drilling within the Creek Zone.
*Gold equivalent (AuEq) is used for illustrative purposes, to express the combined value of Au and Ag as a percentage of Au. Calculations are uncut and no allowances have been made to accommodate potential recovery losses that would occur in a mining scenario. AuEq is calculated using 80:1 silver to gold ratio. Composite results were built using a 0.1 g/t AuEq cut-off, although there are intervals within the composites below 0.1g/t AuEq.
** Intervals are core-length weighted. True width is estimated between 75 to 95 % of core length, and core recovery is estimated to be > 90 %.
***Calculated composites are truncated to significant 2 digits for Au/AuEq and the nearest whole number for Ag.
SH21-044 and SH21-035 were designed to test the mineralized target zone in periphery and underneath the historical small-scale workings, in similar concept to SH21-040 and SH21-040B (see TDG News Release March 29, 2022) and SH21-003 (See TDG News Release January 4, 2022). These holes demonstrate gold and silver mineralization that remains in-situ peripheral to the historical small-scale workings and further highlights the potential for continuity of the mineralized target zone at depth and along strike, and having a component that remains open to the west.
Mineralization is similar to that described in previous news releases of Shasta preliminary results: intensity of quartz/carbonate veining and hydrothermal brecciation appears proportionate to proximity to the Shasta Fault; and an alteration assemblage of strong potassic and subordinate chlorite/sericite alteration with quartz/carbonate veins containing potassic vein selvages, hosting pyrite and acanthite sulphide minerals.
All 2021 drillholes were HQ sized drill core, and historical core are NQ/BQ core size. Particulars for 2021 drillholes (location, depth, etc.)are presented in Table 2. Assay results were received from SGS Labs Canada (“SGS”). Internal QA/QC review by TDG, working with Moose Mountain Technical Services (“MMTS”), is ongoing and therefore results are still considered preliminary.

Samples for the Shasta 2021 drill program followed chain of custody between collection, processing and delivery to an SGS laboratory in Burnaby, B.C. The drill cores were delivered to the core shack at TDG’s Baker Mine site, and processed by geologists who inserted certified reference materials, blanks and duplicates (pulp and coarse) into the sampling sequence. The 2021 drill core was cut in half (1/2 HQ core) and placed in zip-tied polyurethane bags, then in security-sealed rice bags before being delivered directly from the Baker Mine site, to Bandstra Transportation Systems in Prince George, B.C., and ultimately to the SGS laboratory in Burnaby, B.C. Samples were prepared and analyzed following procedures summarized in Table 3, where information about methodology can be found on the SGS Canada Website, in the analytical guide (here).

Quality assurance and control (“QAQC”) is maintained internally at the lab through rigorous use of internal certified reference materials, blanks, and duplicates. An additional QAQC program was administered by TDG Gold through the use of certified reference materials (“CRMs”), duplicate samples and blank 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. For the purposes of this press release, results are ‘preliminary’ and thus have not undergone TDG’s comprehensive QAQC investigations.
The technical content of this news release has been reviewed and approved by Steven Kramar, MSc., P.Geo., a qualified person as defined by National Instrument 43-101.
This news release includes historical drilling information that has been reviewed by the Company’s geological team. The Company’s review of the historical records and information reasonably substantiate the validity of the information presented in this news release; however, the Company cannot directly verify the accuracy of the historical data, including the procedures used for sample collection and analysis. Therefore, the Company encourages investors to exercise appropriate caution when evaluating these results. Further data review is underway, in order to verify the validity of the data for the anticipated NI 43-101 compliant mineral resource estimate.
About TDG Gold Corp.
TDG is a major mineral claim 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, Baker and Mets mines, which are all road accessible, produced intermittently between 1981-2012, and have over 65,000 m of historical drilling. In 2021, TDG advanced the projects through compilation of historical data, new geological mapping, geochemical and geophysical surveys, and, for Shasta, drill testing of the known mineralization occurrences and their extensions. TDG currently has 96,343,142 common shares issued and outstanding.
