TDG Gold Corp. Publishes Third Set of Historical Longitudinal and Cross Sections From Shasta Exploration Area Demonstrating Continuation of Mineralization Along Strike Extending to 1.5 Kilometres
WHITE ROCK, BC / ACCESSWIRE / February 10, 2021 / TDG Gold Corp (TSXV:TDG) (the "Company" or "TDG") is pleased to provide a third 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 north-central British Columbia. The sections presented in this news release cover the Upper Creek and North Zones (see Figure 1). TDG published the zone map of the Shasta Exploration Area within its news release of December 16, 2020 available via the TDG Gold website.
Upper Creek Zone
The Upper Creek Zone is defined as the area between the northern limit of underground workings and mineralization up to 350 metres ("m") due north. The longitudinal sections show that the first 175 m is a continuation of the mineralization seen at the Creek Zone, plunging gently to the north. The mineralization is then truncated and downthrown along a fault and has been encountered at depth in nine holes drilled between 1987 and 1990 which intercepted mineralized quartz breccia at an approximate depth of 220 m to 300 m.
An interval in hole DD90-02 (270 m northwest of the historical workings) starting at 300.5 m returned 10.0 m at 1.42 grams per tonne ("gpt") gold and 31.57 gpt silver. This appears to represent a continuation of the Creek Zone and is open at depth and along strike.
The continuation of the mineralization and the gentle plunge strengthen the interpretation that the ore forming events are stratigraphically constrained. These historical results suggest potential for continued vein occurrences along strike that lie under a cap of younger, unmineralized volcaniclastic sediments. The strike is consistent with regional northwest to southeast trends.
North Zone
The North Zone is a separate vein system that occurs 750 m northeast of the main Creek and JM Zones and follows the same regional northwest to southeast trend. It was initially discovered in 1989 through the drilling of eight holes over a strike length of 300 m and is open along strike. All drilling was shallow with a maximum hole length of 100 m.
North Zone drill results are highlighted by an interval in hole DD89-34 that returned 25.9 m at 2.31 gpt gold and 30.92 gpt silver from a down hole depth of 26.90 m to 52.80 m.
Silver Reef Zone
The Silver Reef Zone is a mineral showing (MinFile Number 094E 145) located approximately one kilometre southeast of the Shasta Mine. The showing consists of quartz vein stockwork and silicified zones over an area of 200 m. The structure follows the regional trend along a northwest to southeast strike and could be an extension of the JM veins which lie 225 m to the northwest which is supported by historical anomalous soil sample results.
Silver Reef was first discovered in the early 1980s but has seen little work since. An assessment report (AR Number 9886, 1981) reports samples collected from a zone of altered volcanic rocks returned grades of 1.028 gpt silver and 0.27 gpt gold. TDG plans on mapping and sampling this zone in 2021.
The orientation and location of the Silver Reef outcrop indicates gold-silver mineralization in the Shasta Exploration Area extends a total of 1.5 kilometres from north to south.
Historical Drill Results and Sections
Figure 1 below shows the location of the two zones for which drill hole longitudinal sections and cross sections are included in this news release (Figures 2-7). All longitudinal sections and cross sections are available in the Shasta project area of the TDG website (https://tdggold.com/projects/shasta/).
Figure 1. Shasta Exploration Area illustrating the location of Creek, Upper Creek and North Zone longitudinal sections and cross sections.
Shasta Exploration Area Longitudinal Sections for Creek/Upper Creek and North Zones
Historical drilling and assay results show gold-silver mineralization continues to the north of the existing surface and underground Creek zone mine workings and remains open to the north, known as the Upper Creek Zone. Sections indicate that the Creek Zone mineralization continues to have gentle plunge to the north before being cut off by a fault and downthrown on the northern block. Significant sections of core were not sampled. The North Zone is an underexplored target zone on the Shasta project; historic drilling has highlighted gold-silver mineralization near-surface.

Table 1 shows historical drill assay results with mineralized widths up to 53.1 m of 1.37 gpt gold and 76.88 gpt silver including 11.4 m of 3.41 gpt gold and 189.64 gpt silver located immediately north 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.
