The Fog North and South occurrences are located near a ridge, approximately 2.5 kilometres north of Ricardo Lake. The exact locations are unknown.

The area is underlain by a persistent band, greater than 12 kilometres long, of stratified metavolcanic and metasedimentary rocks of the Upper Triassic Quatsino and Karmutsen formations (Vancouver Group). The band trends north- west and separates Jurassic to Cretaceous Coast Plutonic Complex rock of two different compositions, diorite and granodiorite.

Locally, quartz veins, up to 1 metre across, host pyrite with gold values.

In 1985, chip samples of two mineralized quartz veins assayed up to 10.98 grams per tonne gold (Assessment Report 15763 and 17067).

The area has been historically explored, since the late 1890’s, in conjunction with the nearby Doratha Morton (MINFILE 092K 023) and Alexandria (MINFILE 92K 028) gold mines. In November 1982, Charlemagne Resources Ltd. optioned 17 reverted Crown grants. Falconbridge Limited entered into an agreement with Charlemagne and in 1985 and 1986 carried out geochemical surveys comprising 1687 soil and 440 rock samples, airborne magnetometer and electro-magnetic surveys over 300 kilometres, and a ground electromagnetic survey over 200 kilometres on the Alexandra and adjacent ground. The area was prospected as the Cordero property in 1991 and 1992 by Ripple Creek Resources. In 2008, Cuda Capital completed a 561.4 line-kilometre airborne magnetic survey on the area.
