The Sue area is underlain by Early Eocene volcanics of the Sloko Group comprised mainly of andesitic to basaltic flows, volcanic breccia, tuff, agglomerate, and minor intercalated volcaniclastics. These are underlain by Upper Triassic Stuhini Group rocks. The strata are intruded by quartz-monzonite stocks and associated feldspar-porphyry dikes which of Tertiary Sloko-Hyder Plutonic Suite.

Volcanic derived greenstones cover most of the Sue area. The metamorphic grade of these country rocks is probably lower greenschist facies, with epidote and chlorite common in the greenstones, and the carbonates are recrystallized and dolomotized.

The sequence of country rocks has been intruded by several igneous phases. A small plug of hornblende diorite was mapped and was found to be barren except for minor pyrite near the contact zone. Other later rhyolite porphyry dikes and feldspar porphyry dikes host minor pyrite mineralization associated with the dike contacts.

In 1980, a small sample taken from a small lens of massive magnetite and pyrite in the greenstone assayed 13.0 grams per tonne silver and 0.125 per cent copper (Assessment Report 8436B).

The area is reported to contain a lead-zinc occurrence, located along the southern edge of a small intrusive plug (Geological Survey of Canada Map 1262A). The only evidence for this occurrence, found during a 1980-1981 exploration program, was a piece of float located north of the claims (Stuhini 104K 050). Mineralization within the float consisted of galena, sphalerite, and bornite in a garnet-epidote skarn (Assessment Report 9107).

In 1979, prospecting east of the Grag claims (Sue area) located a mineralized zone, marked by a gossan striking 020 to 030 degrees, about 150 metres wide and 1200 metres long. The host rock is highly silicified andesite (greenstone), which is crosscut by mineralized quartz veins. The sulphides occur along fractures and joint planes as well as minor disseminations, and include pyrite, pyrrhotite, chalcopyrite, molybdenite, galena, and sphalerite. In 1979, an 8.0 metre sample assayed 2.9 grams per tonne silver, 0.04 per cent copper,and 0.005 per cent molybdenum. Another sample returned 3.9 grams per tonne silver, 0.008 per cent copper, and 0.045 per cent molybdenum. (Assessment Report 7558)

Work History

The Sue 1 and 2 claims were staked by Frank Onucki in 1978 and limited trenching was done in 1979 by Northern Horizon Resource Corporation. The western boundary area of the Sue claims were explored as part of the Grag reconnaissance survey in 1979. In 1980, the Sue claims were being operated by Berglynn Resources Inc. who conducted geological mapping and a sampling program consisting of 3 silts and 31 rocks. This area was south of the area examined by Horizon, near Sittakanay Glacier, and is not part of the claims presently held by Optima Minerals. That part of the area previously held as the Sue claims and examined by Northern Horizon was staked by DeCoors Mining Corp in October 2006 and sold to Optima Minerals Inc in November 2006 and became part of Taku Gold block of the Taku Property. The showing was never visited by Optima.
