TDG Gold Corp. announced the first composite drill results from its 2021 Shasta diamond drill campaign which include 29.0 metres ("m") of 1.78 grams per tonne ("g/t") gold ("Au") with 89 g/t silver ("Ag") [2.89 g/tAuEq] in drillhole SH21-005 and 33.5 m of 1.03 g/t Au with 41 g/t Ag [1.53 g/t AuEq] in drillhole SH21-004 - both within the Shasta Creek Zone south of the historical workings at TDG's Shasta project located in theToodoggone District of north-central B.C. Included in this update are the over-limit assay results from drillholesSH21-004 and SH21-005 which were unavailable in TDG's, alongwith results from drillholes SH21-001, SH21-003 and historical 2007 drillholes re-assayed in 2021 (SH07-001and SH07-002). Results have been received directly from SGS Canada Inc. ("SGS") and whilst SGS has completed its QA/QC protocols for these results, a comprehensive internal Data Quality Analysis ("DQA") byTDG is still underway with subsequent assay results from the Shasta project still pending.

Therefore the results for the purposes of this news release are still considered preliminary. With the additional assay information from drillholes SH21-004, SH21-005 and the 2007 drillholes, cross section 6,347,280 N was constructed offering a more comprehensive understanding of the Shasta Fault system, the high-grade pods of mineralization in proximity to the fault, and the `halo' of Au-Ag mineralization adjacent the high-grade pods. This was previously under-tested by historical exploration and mining efforts.

In addition, the updated over-limit assays from holes SH21-004 and SH21-005 provide true length-weighted composite grades through mineralized intersections, where Au-Ag grades were previously underrepresented by the upper limits of prior analysis. Samples for the Shasta 2021 drill program followed chain of custody between collection, processing and delivery to a 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 2007 drill core was split (1/2 NQ 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 SGS laboratory Burnaby, B.C. Core samples were prepared for analysis according to SGS method PRP89: dry samples to 105°C, crush to 75 % passing 2 mm, split 250 g, pulverize 85 % passing 75 microns.

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.
