The Dry occurrence outcrops along a southeastward-flowing creek, 800 metres west of the south end of 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, various shears cut biotite hornblende granite and quartz monzonite of the Upper Triassic to Lower Jurassic Allison Lake pluton. Some of the shears contain chlorite, calcite, epidote and sericite.
An adit exists on the occurrence near a shear striking 165 degrees and dipping 65 degrees east. Mineralization (in the shears [?]) consists of pyrite, dark sphalerite, chalcopyrite and galena. Some samples are reported to have yielded anomalous gold and silver values (Assessment Report 20179, page 7).
In 1973, 11 character samples of a pyritic shear zone yielded from 2.4 to 34.0 grams per tonne silver and 0.08 to 2.10 grams per tonne gold, whereas a select sample of massive pyrite yielded 70.0 grams per tonne silver and 5.00 grams per tonne gold (Property File 861632).
In 2015, a rock sample (Q980239) of semi-gossanous quartz-feldspar porphyry with pyrite from an outcrop located approximately 1.5 kilometres southwest of the adit (Hazel zone) yielded 0.316 gram per tonne gold (Assessment Report 35820).
Work History
An adit, possibly dating to the 1930s, was developed on the occurrence.
In 1972, Northwind Mines Ltd. completed a program of prospecting, geological mapping and soil sampling on the area immediately east of the occurrence as the J and P claims. In 1973, the area was prospected and sampled as part of the Webber project.
In 1980, Nufort Resources Inc. soil sampled the area as the Dry and Lake claims. In 1988 and 1990, Norsemont Mining Corporation completed geological, geochemical and geophysical surveys over the showing. A northwest-trending copper anomaly was identified that included some zinc and gold anomalies (Assessment Report 20179).
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 2006, Tanqueray Resources Ltd. completed a program of rock, silt and soil sampling on the area immediately southwest of the occurrence as the Otter property.
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 2010 through 2013, Paul Hoogendoorn and Peter Palikot completed programs of prospecting and geochemical (rock and soil) sampling on the area as the Dry Lake property.
Also in 2011, Tatla Mining Partners completed a soil geochemical survey on their property north of the showing, finding elevated gold values up to 15 parts per million (Assessment Report 32777). 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.
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.
