The DD occurrence outcrops on the northwest bank of Allison Creek, approximately 970 metres northeast of the creek's confluence with Borgeson Lake.

Regionally, the area along the Allison Creek valley is underlain mostly by biotite hornblende granite and quartz monzonite of the Upper Triassic to Lower Jurassic Allison Lake pluton. More mafic phases, comprised of granodiorite, diorite and gabbro, are occasionally present within and along the periphery of the intrusion. The north-trending contact with Upper Triassic Nicola Group andesite and basalt lies east of the valley and comes to within a kilometre east of Allison Lake. The pluton is traversed along the east side of the valley by the north-striking Allison fault.

Locally, minor chalcopyrite occurs in association with magnetite in coarse, grey granodiorite of the Allison Lake pluton.

In 1982, two rock samples (Ru6 and Ru7) of malachite-stained metadiorite and quartz float fragments from a scree slope, located near the east bank of the Allison Creek, yielded 0.394 and 0.775 per cent copper, respectively, and up to 4.2 grams per tonne silver (Assessment Report 10499).

Work History

In 1971 and 1972, the occurrence area was prospected, soil sampled and mapped by Laura Mines Ltd. and Northwind Mines Ltd as the DD, J and P claims. In 1980, Nufort Resources Inc. soil sampled the area immediately west of the occurrence as the Dry and Lake claims.

In 1982, the area was prospected and sampled by Gerald McIlhargey as the Rush claim. Later that year, Impala Resources Ltd. completed a soil sampling program on the claim.

In 1990, Norsemont Mining Co. Ltd. completed a program of soil sampling and a 26.0 line-kilometre ground electromagnetic survey on the area as the Dry claims.

In 2009, Orofino Minerals Inc. completed a 922.0 line-kilometre airborne magnetic and gamma-ray spectrometer survey on the area as part of the Allison Lake property. The following year, Orofino Minerals Inc. completed a program of prospecting, geological mapping, geochemical (rock, silt and soil) sampling and 57.0 line-kilometres of ground magnetic and induced polarization surveys on the Allison Lake property.

During 2012 through 2015, Colorado Resources Ltd. completed programs of geological mapping, geochemical (rock and soil) sampling and a 6.0 line-kilometre induced polarization survey on the area as the Hit-Aspen Grove property. Also, in 2014 and 2015, HPX Quesnellia Holdings 1 Inc. completed programs of prospecting, geological mapping, geochemical (rock, silt and soil) sampling and a 622.0 line-kilometre airborne magnetic survey on the area immediately west of the occurrence as the Lisa claims.
