This EJ copper occurrence is located approximately 450 metres east of Summers Creek and 4.0 kilometres northeast of the summit of Missezula Mountain.

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.

The EJ showing is hosted in a sequence of flow breccias and bedded tuffs of the Upper Triassic Nicola Group (Eastern Belt, Bulletin 69). The volcanics are mineralized over a small area with blebs and veinlets of chalcocite up to 6 millimetres in diameter. Blebs and pods of malachite-stained breccia occur 200 metres northeast of the chalcocite mineralization.

In the vicinity, basalt and greenstone (andesite) are occasionally chloritized and mineralized with disseminations and veins of pyrite and chalcopyrite.

Work History

In 1969, a program of soil sampling was completed on the area as the Roadblock claims.

In 1972, Vargas Mines completed a 29.5 line-kilometre ground magnetic survey on the area as the EJ claims. The following year, 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 as the HG and MS claims and completed programs of geological mapping and geochemical (rock and soil) sampling on the claims.

In 1984 and 1985, P.A. Christopher completed programs of soil sampling and a ground magnetic and electromagnetic survey on the area as the MS claims.

In 1991, Fairfield Minerals Ltd. completed a soil sampling program on the area 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 2019, Richard Billingsley completed a program of prospecting, soil sampling and biogeochemical sampling on the area as the Sadim property.
