The Teahan Project, comprising Claims 7848, 7876, and 9853, forms part of Geosearcher Inc.’s Copper – Gold – Silver Projects that were assembled over a six-year period capturing new discoveries of large, at-surface, mineralized systems. The earliest description of the Teahan mineralized zone dates from 1881 and was known as the Goodfellow mine. Early production reports mention mined grades of 15% Cu, 7% Zn, and 2% Pb. During the 1920s, the Consolidated Mining & Smelting Company drilled in the area of the original showing and outlined a “lens” of sulphide-rich material of approximately 300 m with a maximum width of approximately 9 m and to a depth of 100 m. This "lens" may indicate a potential Cobar-type Cu-Au-Zn-Pb-Ag deposit.

During the 2016–2020 exploration seasons, a considerably larger (3 km x 5 km plus) copper-bearing zone was discovered immediately northeast of the historic Teahan Mine. This new zone extends along a major faulted and sheared contact for over 5 km. Of significant note is that exploration also identified a drillable target within the newly identified copper zone. A 1 km wide x 4 km long massive, high amplitude magnetic anomaly also overlies the mineralized faulted contact and it could be highlighting the potential location of a massive lode gold (copper/gold) deposit (yellow lines image 3). This immense and intense magnetic anomaly was confirmed by ground geophysics in the 2017 exploration season (see magnetic survey line of Collier Mountain Road and light blue line on image 3).

Although this is an important copper play, the area highlighted by the magnetic anomaly is also associated with multiple noteworthy gold occurrences. Keirstead Brook, Barrett Brook, and Ferndale Brook are three brooks that drain this area and have historical reports of panned visible gold (VG, see location of VG image 3). Of particular interest is the Ferndale Brook occurrence, which is located northwest of the magnetic anomaly, as large flakes of gold were reported there. These flakes could be attributed to gold plating occurring within the major fault zone identified in the area. Besides the stream VG, there is a historical assay result of 0.44 oz/t Au at the mine site to the south. During recent investigation of the historical mine and surrounding area, the gold was confirmed and is associated with samples that contained hematite and copper sulphides (16BR39 assays 1.5 g/t and 1.8 g/t Au). What enhances the overall picture of this new discovery is that the historical mine site mineralization is lies within a similar, but much smaller, less intense magnetic anomaly (16BR39 and yellow lines image 3). The historical and new discoveries viewed in context together only enhances the possibility and potential of a large orogenic lode gold (copper/gold) deposit lying within this newly discovered mineralized zone.

Highlights: New copper zone along a faulted contact (photos 1 & 2 show outcrops from new copper zone); Historically up to 12% Cu; 0.44 oz/t Au; 14.94 oz/Ag; 14.7% Zn.
