The DUCK showing area is on the north side of Rollie Creek approximately 1.5 kilometres upstream of Keithley Creek Road, west of the south end of Cariboo Lake and 14 kilometres northeast of the village of Likely. Access to the showing is via the main Keithley Creek road and then a network of logging roads.
The Duck property is underlain mainly by metasedimentary rocks of the Upper Proterozoic-Paleozoic Snowshoe Group and granitic gneiss of the Devonian-Mississippian Quesnel Lake Gneiss unit. Pyrite accompanied in places by chalcopyrite occurs as strong disseminations and massive lenses in dark grey phyllites of the Snowshoe Group. Pyrite, chalcopyrite, galena and sphalerite occur in quartz veins cutting the phyllite.
In 1988, drillholes D-1, D-2 and D-3 were positioned to intersect the downdip extension of chalcopyrite-sphalerite-pyrrhotite mineralization exposed in black siltstones about 60 to 100 metres to the south, in the Rollie Creek canyon. The holes intersected abundant and widespread pyrite and pyrrhotite but only weak and sporadic concentrations of chalcopyrite and sphalerite. The sulphides are disseminated throughout an array of grey, greenish grey, green, dark grey and black phyllites. Some of the green phyllites display a distinct volcanic appearance imparted by recognizable relict feldspar or hornblende grains, moderately coarse fragmental textures and a general lack of bedded structure. In drillholes D-1 and D-3, concentrations of 1768 parts per million (0.17 per cent) and 2982 parts per millio (0.29 per cent) zinc occur respectively over six-metre intervals at the contact between black phyllite and green tuffite. Elsewhere, sphalerite and chalcopyrite appear to have a random distribution throughout the assemblage but only in sufficient concentrations to impart slightly anomalous values to the assayed sections. The highest concentrations of iron sulphide appear to be in the black units. Except where contained in quartz-carbonate veins, the sulphides are very fine-grained and not easily seen without magnification even though they may occur in concentrations up to four per cent. It should be noted that the black units encountered in these holes consist of various combinations of soft black graphitic schist, dark grey phyllite and hard black siliceous siltstone, or quartzite.
The Duck claims were staked in 1987 and 1988 to cover sulphide mineralization observed in dark grey phyllites of the Snowshoe Group. In 1987-88, Gibraltar Mines Limited conducted a geochemical soil survey (1306 soil samples), VLF-EM survey (5.4 kilometres) and completed 7 NQ-size drillholes totalling 1033.9 metres.
From 1999 through 2025, Barker Minerals Ltd. conducted programs of geological mapping, float rock, till, soil and stream sediment sampling across several areas on the Frank Creek (Cariboo Lake) property. No work was recorded specifically on Rollie Creek in the area of the Duck prospect.
