TDG Gold Corp. (TSXV:TDG) (the “Company” or “TDG”) is pleased to announce the results of diamond drillhole SH21-006 from its 2021 drill program at TDG’s former producing high-grade gold-silver Shasta Mine located in the historical Toodoggone Production Corridor of north-central B.C. Highlights include 95.5 metres (“m”) of 0.98 grams per tonne (“g/t”) gold (“Au”) and 29 g/t silver (“Ag”) [1.35 g/t AuEq*] from 27.5-123.0 m depth (see Table 1).
As with TDG’s recently published drillholes from the 2021 Shasta drill program (see TDG news releases January 04, 2022 and January 11, 2022), drillhole SH21-006 demonstrates continuity of grade and mineralization along with confirmation of grades of the surrounding historical holes and validation of the expected dimensions of mineralized zone in that section of Shasta (Figure 1). An oblique cross-section is presented in this news release that spans the Creek, JM and Upper Creek Zones (Figure 3).
Drillhole SH21-006 represents the most northerly hole drilled at the Shasta Creek Zone target in the 2021 drill program and spanned the northern portion of the Creek Zone across to the northern portion of JM Zone. The drillhole trace started approximately 150 m north of the Creek Pit and ending approximately 300 m north of the JM Pit (Figure 1). The purpose of SH21-006 was to step out to the north of 2021 drilling and infill between historical drillholes, including SH89-40, SH89-41, SH89-55 and SH89-56 (et al.), highlights from which include 37.0 m of 1.84 g/t Au and 106 g/t Ag [3.16 g/t AuEq*] in SH89-40; and 12.3 m of 1.60 g/t Au and 120 g/t Ag [3.10 g/t AuEq*] in SH89-55 (see Table 2 for historical drillhole highlights).

** Intervals are core-length weighted. True width is estimated between 75 to 95 % of core length.
Drillhole SH21-006 intersected variably silicified, potassic-altered volcaniclastic rocks below the Shasta Fault (at 17.4 m) that carried a mineralized assemblage of dominantly pyrite and acanthite associated with quartz-carbonate veins, composite vein sets and breccias. Sulphide mineralization was identified as disseminated throughout and vein-vein selvage hosted Figure 2 presents the style and grade of typical mineralization encountered.
The northern portions of the Creek, JM and Upper Creek Zones represent areas for potential expansion of the Mineralized Target Zone at Shasta because historical drill holes in the vicinity neglected to sample near surface intervals and instead focused on visually identifying higher grades for assay in concert with typical cut-off grades at the time of mining (~ > 5 g/t Au). With further drilling, this area (Figure 1, and identified in Figure 3) has the opportunity to add minable tonnage to a Shasta resource (if defined) and decrease strip ratio in the vicinity as the closest historical underground workings are over 100 m to the west.

All 2021 drill holes are HQ sized drill cores. Particulars for drill holes (location, depth, etc.) are presented in Table 3. Assay results for remaining 2021 drillholes are still pending at this time.

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. 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 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. Samples were analyzed following procedures summarized in Table 4, where information about methodology can be found on the SGS Canada Website, in the analytical guide (here).
Table 4. Au and Ag Analytical Methods
* Sample C00126417 returned > 1000 g/t Ag in over limit method GO_ICP42Q100, and is currently pending a second over limit using method GO_FAG37V. For purposes of this News Release, Sample C00126417 has been capped at 1000 g/t Ag, and is reflected in any calculations for composite interval purposes.
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.
