The Sweet Home vein showing is similar to the Windpass deposit (MINFILE 092P 039) located 1000 metres to the north. Mineralization is in gold-bearing quartz veins which cut the Devonian to Permian Fennell Formation of the Slide Mountain Group. Both the Windpass and Sweet Home veins dip at variable angles (35 degrees) to the north and cut the western margin of a steeply west-dipping diorite sill and an adjacent bedded chert horizon within the lower Fennell Formation, directly east of the upper Fennell contact.
The Sweet Home vein strikes 290 degrees with varying dips from 10 to 50 degrees north but averages 30 degrees. Within the chert that forms the western wall of the diorite sill, the vein is only centimetres wide and has little sulphide and low gold values. From here, it extends 152 metres to the east where it is thought to be truncated by a northwest-trending fault. It is not known if an offset continuation exists. The Sweet Home vein is comprised of quartz with variable but minor amounts of pyrite and chalcopyrite, bismuth sulphide and telluride in small amounts.
The Windpass showings (MINFILE 092P 039) were discovered and staked in 1916 by Olie Johnson, T.H. Campbell and Oscar Hargen. During subsequent years small shipments of high-grade ore were made from shallow workings. The property was bonded late in 1922 to the Trites, Woods & Wilson interests of Fernie, who incorporated Windpass Gold Mining Company Limited in January 1923. The Sweet Home vein was discovered and staked at about the same time. Ore shipments from the Sweet Home workings began in 1935; production statistics are not available.
The Sweet Home vein was developed by a 36-metre inclined shaft (30 degrees) which connects with a 106-metre crosscut adit, and 137 metres of drift in the footwall of the vein.
In 1969, Kamad Silver Co. Ltd. purchased a lease on the Windpass and Sweet Home claims from J.F.V. Millar, of Calgary. A magnetometer survey and limited trenching were carried out.
In April 1972, Kamad optioned the property to Dalton Resources Ltd. Work during the year included magnetometer and VLF-EM surveys over 31.8 kilometres, stripping and about 152 metres of drilling.
The company name was changed in 1973 to Dalton Developments Ltd. The option agreement with Kamad was terminated in February 1974.
Surveying and sampling of the Windpass and Sweet Home dumps indicated 32 655 tonnes at 6.99 grams per tonne gold and 16 146 tonnes at 0.68 gram per tonne gold, respectively (Sookochoff, April 1973, see Windpass, 092P 039).
Kamad Silver reported a geological review, surveying and sampling of the old workings in 1980 and diamond drilling in 1982 and 1983.
In May 1987, Kerr Addison Mines Limited optioned a 60 per cent interest from Kamad under a joint venture agreement; Texaco Canada Resources Ltd. held a royalty interest. Work by Kerr in 1987 included geological mapping, a magnetometer survey, trenching and 2016 metres of diamond drilling in 11 NQ holes. Highlights include drillhole WP87-07, which returned 1 metre grading 16.3 grams per tonne gold (Assessment Report 16764).
In 2004, Molycor Gold Corp. completed soil geochemistry, surface rock chip sampling, geological mapping, diamond drilling and a magnetometer geophysical survey. Highlights include grab sample W03AR16, taken from the Sweet Home dump, which assayed 1.52 grams per tonne gold and 1.7 grams per tonne silver (Assessment Report 27373).
