WHITE ROCK, BC / ACCESSWIRE / January 18, 2021 / TDG Gold Corp (TSXV:TDG) (the 'Company' or 'TDG') is pleased to provide a second set of longitudinal sections and cross sections from its interpretation work of the historical drilling and exploration undertaken on the former producing high-grade gold and silver Shasta Mine located in the Toodoggone Region of northern British Columbia. The sections presented in this news release cover the JM-Cayley-Rainier Zones and the O Zone.
The JM, Cayley and Rainier Zones lie to the south and southeast of the historically mined Creek and JM Zones (see news release January 05, 2021) and represent geologically continuous mineralized zones, segregated by minor fault offsets. Collation of historical work also highlights the presence of anastomosing vein sets that have been both mapped at surface and intersected during prior drilling, forming a 'horsetail' splay of structures which creates broad zones of near-surface mineralization with an indicated strike length of approximately 1 kilometre with only 300 metres accessed through the historical underground workings.
Historical drill holes within these veins are more widely spaced than within the workings itself but demonstrate comparable widths and grades which remain open to the south and at depth. Previous operators also selectively assayed samples from drill core using visual identification of minerals so the full potential of any mineralized gold-silver halo is currently untested.
An interval in hole DD83-03 in the southern JM and Cayley Zone (190 metres south of historical workings) returned 66.1 metres at 0.51 grams per tonne ('gpt') gold and 8.81 gpt silver, including 9.1 metres of 3.01 gpt gold and 37.29 gpt silver. This appears to represent a central higher-grade mineralized core surrounded by a broader lower-grade halo.
An additional step out 300 metres south within the Rainier Zone returned intervals including 16.2 metres at 2.58 gpt gold and 15.66 gpt silver in hole DD10-05.
Collectively these historical results indicate the potential for consistent mineralization which remains open along strike and at depth.
The O Zone was identified through prospecting and limited drilling during the late 1980s and consisted of limited vein exposures at surface paralleling a fault which appears to be an extension to the JM fault and vein system although there is an untested gap of 350 metres between the two areas. Like other programs on site, assay samples were selected upon a visual assessment and so significant lengths of drill core have not been sampled. Initial reviews suggest mineralization is hosted within a gold-silver bearing breccia along the fault and within the footwall rocks, with sample assays returning intervals such as 3.0 metres grading 2.05 gpt gold and 8.47 gpt silver in hole DD88-25 (see sections below). The O Zone has a known strike length of 320 metres and is open to the southeast and northwest.
Figure 1 below shows the location of the four zones for which drill hole longitudinal sections and cross sections are included in this news release (Figures 2-6). Additional cross sections will be published in the Shasta project area of the TDG website (https://tdggold.com/projects/shasta/).

Shasta Exploration Area Longitudinal Sections for JM-Cayley-Rainier Zones & O Zone
Historical drilling and assay results south of the Creek and JM Zone mine workings are presented here in long section in the target areas known as the JM-Cayley-Rainier Zone and the O Zone. These sections illustrate the southerly extension of gold-silver mineralization from the previously worked Creek and JM zones. The sections demonstrate significant sections of core were not sampled historically. The sections illustrate the potential for further mineralization along strike and down dip.

JM Zone Cross Section
Table 1 shows historical drill assay results with mineralized widths up to 66.1 metres ('m') of 0.51 grams per ton ('gpt') gold and 8.81 gpt silver including 9.1 m of 3.01 gpt gold and 37.39 gpt silver located due south of the former mine workings area. The records show that sections of core were not assayed, and sampling did not continue into vein 'halo' mineralization.

Cayley Zone Section
Table 2 shows historical drill assay results with mineralized widths up to 56.1 m of 0.43 gpt gold and 20.8 gpt silver including 13.7 m @ 0.60 gpt gold and 39.20 gpt silver in an underexplored area located 400 m step out to the south and south-southeast respectively of the southern extents of the JM and Creek Zone historical mine workings. The cross section also illustrates intervals of core that were not assayed.

Rainier Zone Section
Table 3 shows historical drill assay results with mineralized widths up to 16.2 m of 2.58 gpt gold and 15.66 gpt silver including 6.60 m @ 5.58 gpt gold and 22.77 gpt silver in an underexplored area located 490 m step out to the south and south-southeast respectively of the southern extents of the JM and Creek Zone historical mine workings. The section illustrates long intervals of core that were not assayed.

Table 4 shows historical drill assay results with mineralized widths up to 3.0 m of 2.05 gpt gold and 8.43 gpt silver in an underexplored area located 700 m step out to the southeast of the southern extent of the JM Zone historical mine workings.

TDG geologists continue to compile the historical exploration data for the Shasta Exploration Area. Results will be published in the coming weeks presenting additional gold-silver targets. During 2021, subject to operational approvals, TDG proposes to drill test the multiple gold and silver veins and the potential bulk tonnage stockwork mineralization. Successful confirmation of historical drill results and mineralized halo widths will rapidly advance the project to resource definition in 2021-2022.
Drill Hole Details
* Note 1: drill holes with an asterisk denote that assay results are recorded from written reports and government filed assessment reports. Laboratory certificates in these examples have not been found in historical data search. Some records also show that samples were assayed at the Baker Mine Site Laboratory, where no individual assay certificates are recorded.
