The KW (Ridge Zone) occurrence is located on a ridge separating the Toquart River and Ellswich Lake to the east.

The area is underlain by Karmutsen Formation basalts and andesites, and by overlying Quatsino Formation limestone, both of the Upper Triassic Vancouver Group. Stocks of quartz diorite and granodiorite of the Jurassic Island Plutonic Suite intrude the strata.

The Ridge zone consists of a west-northwest trending lineament, up to 250 metres wide, of locally sheared and brecciated Karmutsen volcanics with a number of quartz feldspar porphyry, diorite and minor gabbroic dykes and/or sills. The zone is locally bleached and brecciated and well exposed for several hundred metres of strike length.

The volcanics often contain intense quartz and epidote veinlets and patches of silicification and epidotization. Minor pyrite and lesser chalcopyrite occur in the veinlets and up to 20 per cent disseminated pyrite is occasionally present in the volcanic rocks. Similar amounts of pyrrhotite are much less common. Diamond-drill hole R89-26 intersected a silicified zone containing up to 20 per cent pyrite and a few sections carrying chalcopyrite as veinlets or disseminations. Jasper may be present in quartz veins where rocks are brecciated and bleached.

In 1905, the area was originally staked as the Red Rover Property (MINFILE 092F 034). Between 1920 and 1938, various operators completed programs of partially stripping the main vein and two adits were driven. Between 1972 and 1982, minor exploration programs and sampling of the main vein were completed. In 1983, J. Barakso acquired the property and completed silt, soil and rock chip sampling programs. In 1985, Falconbridge optioned the property and completed exploration programs including 332 metres of diamond drilling. In 1987, Electrum Resources optioned the property to Freemont Gold Corp. and completed programs of VLF-EM and magnetometer surveys, soil and rock sampling and geological mapping. In 1988, Canora Mining joined the joint venture and completed a twenty hole diamond drilling program, totalling 2,087 metres. Between 1991 and 2011, Electrum Resources completed various programs of VLF-EM and geochemical surveys, including five diamond drill holes in the TOQ zone totalling 826 metres (MINFILE 092F 542).
