The Swamp Zone is covered by the Brian 338094 and Lone 1 claims, a part of the Lone Peak property. The showing is located near Fisher Creek, immediately north of Lone Mountain, approximately 30.5 kilometres east of Kimberley. The property, including the Magnet (MINFILE 082GNW001) and Lone Peak (MINFILE 082GNW093) showings, have been explored since the mid-1990’s by prospector B. Kostiuk. For a complete history refer to Assessment Report 31651.
Regionally, the area is located on the eastern edge of the Belt Basin. The Belt Basin is formed by the Middle Proterozoic Belt Super group. The Purcell Super group is comprised of a thick accumulation of calcitic and carbonate rocks that are interpreted to have been deposited in a large intercratonic basin.
Locally, the area is underlain by moderately north-dipping sediments of the upper part of the Creston Formation and the lower part of the Kitchener Formation. The Creston Formation consists mainly of medium- to thick- bedded mauve siltstone and white quartz arenite, overlain by interbedded green argillaceous siltstone and minor quartz arenite. The Kitchener Formation conformably overlays the Creston Formation. The Kitchener Formation is composed mainly of carbonate and carbonate- rich calcitic sediments of thinly laminated dolomite, buff and light green dolomitic siltstone, argillaceous dolomite, rare oolitic limestone, green siltstone and massive dolomite.
Mineralization is reported, from bedrock rock chip samples, as quartz/carbonatite veins with arsenopyrite and pyrite hosting gold values.
In 1998, rotary air drilling was performed and intercepted Creston Formation sediments, at 40.2 metres depth, containing gold and auriferous pyrite. A panned concentrate sample from a 0.60 metre section returned up to 32005 parts per billion gold (Hole BK98-1; Assessment Report 25972).
In 2000, rotary drill hole BK20/00 returned 35.0 grams per tonne gold from a 0.60 metre section of panned concentrates (Assessment Report 26319).
In 2002, five diamond drill holes, totalling 1391.9 metres were completed within the area of the previous rotary drilling. The best pyrite mineralization encountered was in hole LPO2-1 from 41.5 to 68.5 metres. A grab sample from this zone returned values of 1335 parts per billion gold and 23 parts per million cobalt (Assessment Report 26942).
