Overview
The Talisman Historic Copper-Silver Mine is located approximately 95 kilometres by highway to the Teck Trail Smelter. Mineralization at Talisman is stratabound and appears to be skarn related. Adamera has recognized numerous similarities to stratabound Copper -silver deposits in Montana. Exact production records of the historic mine are not available, however, 521 tons of ore shipped during the early 1900’s are reported to have averaged 5% copper, 3 opt (102.9 g/t) silver, and 4.1% zinc. This is consistent with the results obtained by the Company west of the known mine site.
Samples from an initial program in yielded mineralization as high as 144 g/t silver, 3.45% copper, 6.3% lead and 6.91% zinc. A magnetic survey defines a large magnetic high anomaly southwest of the mine that appears to be associated with this mineralization.
In 2021 a follow up field program included mapping, prospecting, sampling and geophysical surveying. The work identifies zones of previously undocumented mineralization that demonstrate exploration potential. New data generated during the 2021 program has led the company to reevaluate the deposit model for Talisman.
Selected grab samples highlighting anomalous to high-grade values. The 1000 g/t Ag is above detection limit of the analytical method and requires additional analysis to determine exact amount of Ag.
Some of the zones could be rapidly advanced to drill testing. Key findings from the program include:
- New Talisman mineralization is exposed intermittently over an area measuring more than 800 x 1100 metres within a westerly trending, gently dipping metasedimentary unit.
- Identification of new mineralized stratigraphic horizons increasing the scale potential of the mineralized system.
- High grade mineralization occurs within a broad zone with active magnetics and is locally associated with strong magnetic lows
- Sulfide mineralization includes bornite, chalcopyrite, sphalerite, galena, and pyrite in association with magnetite and silver bearing minerals.
- No previous drilling has been conducted near the new mineralized zones.
With current metal prices and proximity to Teck’s smelter in Trail BC. This project is a strategic land holding and the company is considering options to advance the project including partnership opportunities with a base metal focused company. A recommended follow up program would include a ground electromagnetic survey to outline massive to semi-massive sulfide mineralization. Drilling would follow to determine the sulfide distribution and grade at depth.
