The Darcy property is centred around the contact of a large, elongate body of Triassic-Jurassic picrite which has intruded Upper Triassic Nicola Group volcanic rocks along a northwesterly axis. The most common volcanic lithology is green, fine to medium-grained tuff, but ash tuff, tuff breccia and fine to medium-grained porphyry also occur. These rocks have been affected by pervasive chlorite-sericite- epidote? alteration and varying degrees of carbonatization. Sedimentary rocks include grey, laminated argillite, grey to black siltstone and conglomerate. Disseminated pyrite is common in siltstone and is locally present in argillite. Volcanic rocks of unknown age resembling the Eocene Kamloops Group (olivine present, amygdaloidal) appear to be associated with picrite and are assumed to be older than (or coeval with?) picrite (Assessment Report 14194). The picrite occurs as an elongate intrusive mass about 7 by 4 kilometres in size whose long axis is oriented in a northwesterly direction. Widespread alteration is characterized by serpentine, clay, magnetite, hematite and sericite.

Three showings have been located on the Darcy property. The discovery subcrop on Grid A consists of carbonate-potassium feldspar altered picrite and volcanic breccia cut by quartz sulphide veins. Grab samples analysed between 0.48 up to 7 grams per tonne gold and 0.11 to 0.14 per cent copper. Sulphides comprise minor amounts of bornite, chalcocite, covellite, tetrahedrite?, chalcopyrite and pyrite. The discovery showing is located within the boundaries of the Pass Lake Research Substation owned by Agriculture Canada who have refused application to allow further exploration work on their property (ca. 1988). On Grid B, located along Watching Creek about 4000 metres north of the discovery outcrop on Grid A, gold values are associated with tetrahedrite, pyrite, chalcopyrite, chalcocite, covellite, pyrite, rare native gold and/or sphalerite in carbonate and quartz veins in an area of carbonate-potassium feldspar altered picrite and volcanic rocks. At the Watching Creek showing, located about 2000 metres north of the Grid A showing, hornblende feldspar porphyries intrude picrite. There are significant strong fracture zones with abundant quartz vein stockwork and associated albite-sericite-carbonate-chlorite-epidote-pyrite alteration. Anomalous gold (up to 0.26 gram per tonne) is related to alteration associated with quartz vein stockworks and disseminated pyrite (Assessment 14194). A best assay from drilling in 1988 at the Watching Creek showing yielded 2.08 grams per tonne gold and 6.3 grams per tonne silver over a 0.5 metre intersection (Assessment Report 17413).

The Darcy claims were staked by Esso Resources in September 1984 to follow-up a grab sample that yielded high gold values. Work conducted in 1985 by Esso Resources comprised geological, magnetometer and VLF-EM 16 surveys, soil and rock sampling, trenching, test pits and access road. In 1987-88, Esso Resources completed 1.3 kilometres of drill access roads, soil, silt and rock sampling, geological mapping and 3 diamond-drill holes totalling 200 metres.
