The Duchess occurrence is located west of the Ingenika River approximately 17 kilometres northwest of Johanson Lake.
The Duchess occurrence area is underlain by the Upper Triassic Savage Mountain Formation (Takla Group) consisting of augite porphyry basalt flow, breccia, pillow breccia, tuff and interbedded bladed feldspar porphyry.
In 2015, Pacific Empire collected a grab sample of strongly epidote and clay-altered augite-phyric basaltic andesite with about 1.5 per cent combined chalcocite and bornite blebs. This sample graded 1.813 grams per tonne gold, 29.79 grams per tonne silver, and 3.54 per cent copper (Sample 2086927, Assessment Report 35685). Sample 21086931, about 200 metres west of sample 2086927, was collected from a shear vein with epidote and bornite over 4 centimetres; this grab sample graded 39.70 per cent copper, 220 grams per tonne silver, and 0.3 gram per tonne gold (Assessment Report 35685). Samples about 300 metres northeast of sample 2086927 were up to 1.8 per cent copper.
WORK HISTORY
In 2015, Pacific Empire Minerals Corp. collected 15 rock samples and completed a 4 line-kilometre IP survey over the main target area, from the Copper King showing (094D 149) towards the ING (094D 151) showing (Assessment Report 35685). Rock samples were collected southwest of Copper King and D.S. (094D 004) and north and northeast of Bornite (094D 037).
See Copper King (094D 149) for details of work done in the immediate Duchess vicinity from 1973 to 2018.
