The following quoted text is from Minfile.
"The Charlie (Warren) occurrence is located west of the Tchaikazan River at an elevation of approximately 2100 metres.
The area is underlain by volcanic and sedimentary rocks of the Lower Cretaceous Taylor Creek Group, consisting of feldspar crystal tuffs, lithic fragmentals, and some flow rocks with chloritic amygdules. Argillaceous sediments are a minor component of the succession. These have been intruded by Late Cretaceous to Paleogene dioritic and feldspar porphyritic rocks.
Locally, at least five mineralized, 10 to 50 centimetre wide, quartz-carbonate veins (Charlie, Big, Avalanche, East and DK) have been identified. Mineralization is reported to consist of pyrite, pyrrhotite, galena, altaite, hessite, chalcopyrite, sphalerite, native gold and wehrlite. Secondary minerals include limonite, hematite, epidote and chlorite. The area is dominantly propylitic- altered with minor earlier potassic alteration.
The Big vein is located approximately 300 metres to the north west, while the DK vein is located approximately 300 metres up slope, the Avalanche vein is located approximately 900 metres to the north and the East vein is located approximately 1000 metres to the east- north east. Malachite mineralization is also reported in the area of the Avalanche vein. The Charlie vein has been followed along strike for 150 metres and the Big vein has been traced for 275 metres.
Mineralogical compositions and textures of the vein mineralization suggest precipitation at a high structural level, above the disseminated chalcopyrite mineralization (Hub occurrence) exposed in the valley floor. In other words, the vein mineralization was precipitated from the same hydrothermal system from which copper mineralization was deposited at a deeper level.”

The three telluride minerals noted were X-ray confirmed (Thompson, 1949).
