The Family Farm occurrence is situated on the north side of Mica Peak (East Mica Mountain), 6.5 kilometres southwest of Williston Lake and approximately 86 kilometres north of the community of Germansen Landing.
The area is underlain by regionally metamorphosed miogeoclinal rocks of the Neoproterozoic Ingenika Group. In the vicinity of the showing, these metasediments largely comprise quartzites and schists.
According to Geological Survey of Canada Summary Report 1927, all mica-bearing pegmatites in this area consist of feldspar and quartz, and small amounts tourmaline, garnet, and pyrite. 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. One pegmatite dike in the area is also reported to have contained a well-developed crystal of pale bluish green beryl.
The Family Farm occurrence comprises two concordant dikes of white pegmatite, intruding schist and consisting of mostly muscovite, quartz, and feldspar. The larger dike forms an elongate ellipsoid that strikes 150 degrees, dips 70 degrees west and plunges up to 12 degrees towards 150 degrees, with long and intermediate axis of 100 metres and 12 metres, respectively. This dike varies up to 10 metres wide. Muscovite crystals, up to 13 centimetres in diameter, occur in the pegmatite, with the larger grains generally within 1 metre of the wallrocks. The muscovite is reported to be of excellent quality despite some surface weathering.
The smaller, parallel pegmatite dike of similar shape occurs about a hundred metres northeast of the larger one. Although pyrite, tourmaline and garnet are more abundant, only minor amounts of muscovite mica are present in this dike.
The larger dike was explored by a shaft and several drifts, while the smaller one was trenched by General Holdings Company Ltd. between 1925 and 1927. The company extracted up to 2.3 tonnes of raw mica from the workings in 1927 (Minister of Mines Annual Report 1927, page 161).
In 2005, Guardsmen Resources Inc. acquired the Mica Peak property, which covers the Family Farm 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 and Birthday (094C 124), were briefly examined.
