The BO occurrence lies along the west bank of Summers Creek, approximately 23 to 26 kilometres north of Princeton.

The area along Summers Creek is underlain by the Eastern volcanic facies of the Upper Triassic Nicola Group, comprising mafic, augite and hornblende porphyritic pyroclastics and flows, and associated alkaline intrusions.

Locally, sparse bornite and chalcopyrite occur in discontinuous calcite veins in andesitic pyroclastics of the Upper Triassic Nicola Group (Central Belt, Bulletin 69).

In 1981, a rock sample (RX42636) of rhyolite hosting a quartz vein with pyrite and chalcopyrite, located approximately 1 kilometre west-southwest of the BO occurrence, yielded 0.126 per cent copper (Assessment Report 4346).

Work History

The occurrence area was mapped and soil sampled by Texas Gulf Sulfur Company Ltd. in 1971. The following year, Vargas Mines completed a 29.5 line-kilometre ground magnetic survey on the area immediately north of the occurrence as the EJ claims. In 1973, Calcio Silver Mines Ltd. completed a program of geological mapping and geochemical (rock and soil) sampling on the claims.

During 1979 through 1981, Newmont Exploration of Canada Ltd. held the area immediately north of the occurrence as the HG and MS claims and completed programs of geological mapping and geochemical (rock and soil) sampling on the claims. During 1981 through 1984, Canadian Nickel Co. Ltd. completed programs of prospecting, geological mapping, geochemical (rock and soil) sampling and ground geophysical surveys on the area as the Hit 1-4 and Miss 1-2 claims.

In 1990 and 1991, Vanco Explorations Ltd. completed programs of geological mapping, geochemical sampling and ground geophysical surveys on the area as part of the Hit and Miss property. Also in 1991, Fairfield Minerals Ltd. completed a soil sampling program on the area immediately east of the occurrence as the Zu 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. In 2017 and 2018, Colorado Resources Ltd. completed further programs of rock sampling and a historical induced polarization processing and inversion on the area as the Hit property.

In 2019, Richard Billingsley completed a program of prospecting, soil sampling and biogeochemical sampling on the area as the Sadim property.
