Company Update

WHITE ROCK, BC / ACCESSWIRE / January 5, 2021 / TDG Gold Corp (TSXV:TDG) (the "Company" or "TDG") is pleased to provide an update on its interpretation work of the historical drilling undertaken on JM and Creek-Shasta Zones of the former producing high-grade gold and silver Shasta Mine located in the Toodoggone Region of northern British Columbia.

Interpretation of historical data demonstrates gold and silver bulk tonnage potential surrounding the former mined areas of the JM and Creek Zone veins (Figure 1) together with their mineralized strike extensions to the south and south-east. Select drill logs and assays show gold and silver mineralization extends into host rock and vein stockworks in widths up to 100 metres. Only 63% of historical drill core was assayed and therefore there remains the potential to increase mineralized widths in several areas through resampling of historical core and drilling of new holes.

Shasta Historical Workings

A preliminary site assessment and reconstruction of historical mine working data was undertaken by Tetra Tech Inc. All mine levels, stopes, pits and access drifts were recreated from historical mine working drawings. Tetra Tech also provided a final estimated volume extraction from the 300-metre length JM Zone and the 300-metre length Creek Zone totaling approximately 420,000 tonnes including ore and waste.

Figure 1. Underground mine and pit mine workings in 3D created from historical mine plans.

Further to TDG's news release of December 16, 2020, twelve mineralized zones have been outlined at Shasta using historical and publically available data. The regional Shasta exploration target covers an area approximately 800 metres by 1500 metres. Eleven of the twelve mineralized zones at the Shasta project were previously drilled although some targets are only represented by extremely limited numbers of drillholes. This news release focuses on historical data for the known Creek-Shasta and JM Zones covering a strike length of approximately 750 metres.

Figure 2 below shows the location of the three zones for which drill hole longitudinal sections and cross sections are included in this news release (Figures 3-7). Additional cross sections will be published in the Shasta project area of the TDG website (https://tdggold.com/projects/shasta/).

Shasta Area Longitudinal Sections for Creek-Shasta and JM Zones

Historical drilling and assay results show gold-silver mineralization is present surrounding the voids of the Creek and JM Zones mine workings and is also open to the north and south. Significant sections of core were not sampled.

Table 1 shows historical drill assay results with mineralized widths up to 38.1 metres ("m") of 1.13 grams per ton ("gpt") gold and 44.93 gpt silver within the former mine workings area. The records illustrate that sections of core were not assayed, and sampling did not continue into "halo" mineralization.

TDG geologists continue to compile the historical drill data longitudinal sections and cross sections for the other mineralized zones identified in the Shasta Exploration Area. Results will be published in the coming weeks. 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.
