The Bluestar occurrence is located on a southeast-trending ridge, west of Limpid Creek and approximately 1 kilometre northwest of the creek’s junction with the Pend D’Oreille River.

Regionally, the area is underlain by quartzites, pelites, phyllites, limestone and argillites of the Cambrian Laib Formation; mudstone, siltstone, shale and fine clastic sedimentary rocks of the Lower Jurassic Archibald Formation (Rossland Group); basaltic volcanic rocks of the Lower Jurassic Elise Formation (Rossland Group) and undivided Paleozoic sedimentary rocks. Granodioritic rocks of the Cretaceous Anstey pluton are exposed to the northeast.

Locally, quartz veins occur along a north-trending shear zone cutting siliceous argillite, phyllitic argillite and calcareous argillite. The quartz carries minor disseminated pyrite and occasional flecks of chalcopyrite, galena and sphalerite. Carbonate, sericite and ankerite are reported associated with the quartz veins. The mineralized zone strikes between 150 and 160 degrees with a dip of 65 to 70 degrees west and is on the order of 1 to 3 metres wide and traceable along strike for approximately 500 metres. A subparallel vein is reported approximately 300 metres to the west.

In 1939, a select sample from the surface workings of the You and Me claims is reported to have yielded 13.7 grams per tonne gold, 137.1 grams per tonne silver, 4 per cent lead and 2 per cent zinc (Assessment Report 30475).

In 1983, a chip sample (CA-29) from the adit assayed 0.42 gram per tonne gold over 1.8 metres (Assessment Report 11536).

In 1984, a sample (C-46) from the adit assayed 1.02 grams per tonne gold (Assessment Report 13489). Other samples from 1984 are reported to have yielded 2.6 grams per tonne gold over 3.2 metres and 2.4 grams per tonne gold over 1.8 metres, wheras a random grab sample from the adit dump assayed 11.8 grams per tonne gold with 12.6 grams per tonne silver (Assessment Report 30475).

In 2008, a sample (918339) assayed 4.31 grams per tonne gold and 7.0 grams per tonne silver (Assessment Report 30475).

In 2009, sampling (973855) of the adit and adjacent opencuts yielded up to 91.6 grams per tonne gold and 39.3 grams per tonne silver, whereas dump samples yielded up to 8.05 grams per tonne gold, 16.4 grams per tonne silver, 0.542 per cent lead and 0.600 per cent zinc (Assessment Report 31577).

The area has been historically explored since the late 1800s in conjunction with the nearby Bunker Hill (MINFILE 082FSW002) past-producing mine. By 1934, the area had been staked as the You and Me claim. In 1939, the area was staked as the Blue Ridge mineral claim and four areas of surface workings along with a 6-metre long adit were reported on occurrence.

In 1974, a single 49.94-metre long diamond drill hole was completed. In 1980, a program of rock sampling and a 1.2 line-kilometre ground VLF-EM survey was completed on the area as the Zap claims. In 1983 and 1984, Rex Silver Mines Ltd. completed programs of rock, silt and soil sampling; geological mapping and a ground electromagnetic survey on the area as the Waneta 1-10 claims.

During 2007 through 2013, Clarke Gold Inc. conducted programs of geological mapping, soil, silt, heavy mineral and rock sampling on the area as the Nox Fort and CLY properties.
