Bot
Overview
The BOT project consists of over 8,600 hectares located approximately 40 kilometres north of TDG’s 100% owned Baker-Shasta gold-silver project, adjacent to Evergold Corp.’s Golden Lion project in the Toodoggone District of north-central B.C. In 2021, Evergold drilled and discovered the ‘GL1 Main’ Zone, which carried high-grade Au-Ag and appreciable concentrations of base metal.
BOT covers a relatively underexplored portion of the Toodoggone, has never been drilled, and presents a high-calibre, frontier-level project for TDG with copper and gold-silver potential. It further augments TDG’s portfolio of assets, which include the road-accessible, former-producing high-grade gold-silver Shasta, Baker and Mets mines.
History
BOT is host to numerous previously identified precious and base metal mineral showings (MINFILEs). Evidence of hydrothermal alteration at BOT is observed in surficial gossans. These gossans have anomalous supporting precious and base metal concentrations in geochemical sampling completed to date.
TDG’s technical team has completed the re-assembly and analysis of historical reports and data that detail the exploration history at BOT from 1969 to present. In combination with the 2021 survey work, TDG now has access to 1,459 line-km of high-resolution airborne magnetic and radiometric surveys.
2021 Airborne Magnetic Survey
During the 2021 exploration season, TDG completed an airborne magnetometer survey covering BOT, performed for TDG by Precision GeoSurveys Inc. This survey provided high-quality magnetic data to supplement TDG’s existing database of geochemistry and geophysics to assist with prioritizing target zones for follow up work. The TMI (Total Magnetic Intensity) results are shown here.
Mineralization
Intense oxidation has developed extensive areas of limonite gossans, the largest of which measures 1000 m x 200 m, and is located topographically above the previous high-grade Au sample sites. Cu-Au stream sediment anomalies are observed within the creeks that incise into the above gossanous slopes, with values ranging from below detection to up to 740 ppm Cu and 640 parts per billion (“ppb”) Au, respectively. Background values for this region are < 50 ppm Cu and < 25 ppb Au.
A property-scale airborne hyperspectral survey is planned as the initial follow up of the data compilation by company geologists, to aid in vectoring using clay speciation and alteration mineral trends. 60 line-km of high- resolution deep IP surveys are also planned on east-west trending survey lines over Moose hydrothermal system to test chargeability to depth. A three-year MYAB (Multi Year Area Based) permit application had been submitted to complete 2022 work and anticipate drilling in 2023.
High Priority Targets
Silver Cirque Showing – 094E 255
Porphyry Cu +/- Mo +/- Au
Epithermal Au-Ag: low sulphidation
The Silver Cirque occurrence is located on the western flank on Mount McNamara. Silver Cirque is hosted in a 500 metre x 500 metre (“m”) alteration zone containing sphalerite, galena, chalcopyrite and minor tetrahedrite mineralization. Select grab sampling completed by previous operators contained values ranging from below detection up to 26.96 grams per tonne (“g/t”) Au and 1,350 g/t Ag.
Stockwork Zone Showing – 094E 254
Porphyry Cu +/- Mo +/- Au
The Stockwork Zone is located 3.5 km southwest of Mount McNamara. Mineralization is best developed along north-south structures that mimic the geometry of a strong ZTEM chargeability anomaly, detailed below. The mineralized zone has approximately 1% quartz stockwork with veins ranging from 3 mm to 30 cm. Rock geochemistry values at the Stockwork showing range from 11 parts per million (“ppm”) up to 1% Cu and below detection up to 9.5 g/t Au.
Regal Showing – 094E 253
Porphyry Cu +/- Mo +/- Au
Epithermal Au-Ag: low sulphidation
The Regal showing is located roughly 3.3 km south of the Stockwork showing. The geology is similar to the Silver Cirque showing to the north, where marine and volcanic rock is intruded by monzonite and granodiorite stocks.
The Regal showing mineralization in quartz +/- specularite veins as individual veins and stockworks, which contain a range from below detection to 59.8 g/t Au and below detection to 144 g/t Ag (ARIS 28037). The showing was extended to the south by Talisker Resources Ltd. in 2019 (prior to TDG’s acquisition of Talisker’s Toodoggone properties in 2020) with additional values ranging from below detection up to 9.89 g/t Au, confirming the anomalous gold and silver values in the previous sampling. The Regal showing is located near the southern termination a major 7000 m x 400 m 3D ZTEM chargeability anomaly, at 90Hz frequency.
Moose Showing – 094E 020
[Note: the mineral claim containing the Moose MINFILE occurrence is held by a third party; TDG has the surrounding claims]
Porphyry Cu +/- Mo +/- Au
Cu skarn
The Moose showing is located in the southern portion of the BOT tenure group, below a high ridgeline to the east of Moosehead Lake. Historic reporting describes widespread copper mineralization, disseminated chalcopyrite with individual samples ranging from below detection to up to 1% Cu. Overlimit assays were not completed on the historic sampling. Mineralized quartz veins also occur which contain values ranging from below detection to up to 168 g/t Ag and below detection to up to 205.3 g/t Au. A second sample of this stockwork taken 90 m to the west also contained 68.4 g/t Ag and >100 g/t Au. No overlimit assay was completed for Au analysis.
