Historical Drilling Results Demonstrate Bulk Tonnage Potential At Former Producing Gold-Silver Shasta Mine
WHITE ROCK, BC - TDG Gold Corp reported 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 meters. 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.
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-meter length JM Zone and the 300-meter length Creek Zone totaling approximately 420,000 tonnes including ore and waste.
Twelve mineralized zones have been outlined at Shasta using historical and publiclyavailable data. The regional Shasta exploration target covers an area approximately 800 meters by 1500 meters. 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 information is focused on historical data for the known Creek-Shasta and JM Zones covering a strike length of approximately 750 meters. 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.
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.
