The RCJV 7-10 occurrence is located east of a small lake, referred to as Loon and later Kidney Lake, between Boomerang and Hay creeks at an elevation of approximately 1240 metres.

Regionally, the area is underlain by Middle Jurassic granitic intrusive rocks and undivided intrusive rocks of the Cretaceous Ladybird and Valhalla Intrusions (Okanagan Batholith), which are overlain by undivided volcanic rocks of the Eocene Penticton Group.

Locally, three (A, B and C) mineralized and fractured quartz-chlorite veins, up to 3 metres wide, have been identified in a quartzite host associated with a rhyolite porphyry and granite intrusive. Mineralization comprises pyrite, pyrrhotite and molybdenite. The veins strike 210 to 240 degrees and dip 50 to 65 degrees east.

In 1980, a sample (19851) from the tailings of the No. 1 shaft yielded 0.1 gram per tonne gold and 0.44 per cent molybdenum (Assessment Report 8929).

In 2015, a float sample (Poplar-011) taken to the south assayed 0.442 gram per tonne gold (Assessment Report 35864).

Another area of mineralization and former workings, comprising a 7-metre long adit or shaft and a former ‘miners’ cabin, are reported approximately 1.7 kilometres to the west-northwest. Mineralization comprises an andesite porphyry and/or diorite hosting a fractured and oxidized quartz zone with sulphides. Galena, pyrite and possibly sphalerite are reported in the tailings. Fuschite is also reported in this area.

In 2013, a rock sample from the adit/shaft area yielded 0.174 per cent lead, 0.100 per cent zinc and 2.7 grams per tonne silver, whereas another sample (VGM-002) assayed 0.019 per cent molybdenum (Assessment Report 34584).

The area has been explored since the late 1800 or early 1900s, with at least two shafts likely dating to this period. In 1980, a program of prospecting and rock and soil sampling was completed on the area as the RCJV 7-10 claims. During 2013 through 2016, programs of prospecting and rock sampling were completed on the area as the Boomerang property.
