The Rhea (or Reah) showings are located in the Copper Mountain Lookout area, 13 kilometres southwest of Nelson. The earliest known work was done before the 1920's.

The area is underlain by volcanic rocks of the Lower Jurassic Elise Formation, Rossland Group which have been intruded by granodiorite to quartz monzonite of the Middle to Late Jurassic Nelson Intrusions. The Red Mountain fault occurs to the east of the claims area. The volcanic rocks comprise tuffs, plagioclase crystal tuffs, lapilli tuffs and andesite tuffs. The volcanic stratigraphy is intruded by aplite dykes and small stocks.

Several quartz veins occur conformable to the local foliation on the southwestern flank of Copper Mountain. The white quartz veins have been sheared and host erratic metal values. Mineralization consists of pyrite, pyrrhotite, tetrahedrite, chalcopyrite, malachite and arsenopyrite.

The Rhea vein, in a strong vertical shear, is 0.3 to 1.5 metres wide and has been traced for 300 metres. It strikes 47 degrees and dips 76 degrees east. Reported gold values vary from trace to about 1.6 grams per tonne with equally low and erratic base metal values. A sample of high grade material taken from the dump assayed 9939.0 grams per tonne silver, 2.48 per cent copper, 0.15 per cent lead and 0.28 per cent zinc (Assessment Report 12720). Sampling of the vein itself in 1985 resulted in a best assay of 1.37 grams per tonne gold and 25.37 grams per tonne silver (Assessment Report 14280). The Tetrahedrite or Extension vein, just to the south of the Rhea, is similar in mineralization and trend. This vein, however, dips 40 to 50 degrees east. It has been exposed for 50 metres. The highest assay was 16.45 grams per tonne gold, 1585.8 grams per tonne silver, 0.2 per cent copper, 0.78 per cent lead and 0.04 per cent zinc (Assessment Report 14280). The O.G.G. vein outcrops about 800 metres to the north and east of the Rhea vein and is parallel to it.

In 2011, a sample from the area assayed 0.17 per cent copper and 3 grams per tonne silver (Morris, R.J. (2012-03-27): Property of Merit Report– West Kootenay Properties – Big Strike Project).

Work History

Placer mining has taken place in the area of the Rhea-Sirush Property since the late 1800s. Seven shallow adits were driven prior to 1984, to test an arsenopyrite-bearing quartz vein/zone. There are also multiple other adits and trenches reported, the locations of which have not been confirmed.

in the 1980s and early 1990s, exploration programs including hand trenches and pits, and an extensive soil sampling program were completed on the area as the OGG claims.

In 2011, Moose Mountain Technical Services, on the behalf of Rainbow Resources Inc., completed a program of prospecting and geochemical (rock and soil) sampling on the area as the Big Strike property.
