The West Mica Mountain mica occurrence is located on the north side of West Mica Mountain, 84 kilometres north of the community of Germansen Landing.

Hostrocks are pegmatites within mica schists and gneisses and quartzites of the Neoproterozoic Ingenika Group which have been metamorphosed to the kyanite zone of the amphibolite facies of regional metamorphism. The showing is described as the richest pegmatite dike in the Mica Mountain mica district; apparently, large muscovite crystals (possibly up to 33 centimetres across) have been extracted from the deposit and a small shipment made (Geological Survey of Canada Summary Report 1927, Part A, page 33A). The mode of occurrence is described as similar to the Mica Mountain (094C 034) located 3.7 kilometres to the northeast.

All mica-bearing pegmatites in the area are reported to be formed of feldspar and quartz with small amounts of pyrite, tourmaline, and garnets. The tourmaline occurs as small, well formed, jet-black crystals frequently arranged in rosettes, and commonly found in the country rocks adjoining the pegmatites. The garnets are bright ruby-red in colour.

In 2005, Guardsmen Resources Inc. acquired the Mica Peak property, which covers the West Mica Mountain showing, in hopes that appreciable rare earth elements may be found in association with pegmatite zones. During a 1996 visit, heavy snowfall limited exploration to stream silt sampling. Unfortunately, exploration in 2007 was limited to the westernmost part of the property. In 2010, Guardsmen Resources Inc. conducted a two-day reconnaissance silt and rock geochemical sampling program; two mineral prospects, Family Farm (094C 034) and Birthday (094C 124), were briefly examined.
