The area is underlain by Middle Jurassic Yakoun Group rocks dominated by pyroclastic andesites and lesser massive andesite, conglomerates, volcanic sediments and argillites. These rocks are cut by quartz diorites and porphyritic felsic dikes.

The dominant structure on the property is a major west northwest trending fault zone (Rennell-Louscoone fault system), with associated splays and subparallel faults. The fault system appears to control the mineralization and alteration.

Carbonate-sulphide-sericite-silica alteration occurs in a zone up to 500 metres long and 120 metres wide. The abundance of carbonate in the area may express mobilization of the limy fraction of the underlying Juro-Triassic Kunga Group.

Disseminated and fracture filled pyrite, stibnite and arsenopyrite, associated with quartz and calcite veins occur within pyroclastics and clay-carbonate altered andesite, along the major northwest trending fault zone. A clay-like "gumbo zone" with breccia textures appears to be derived from pyroclastics, but also, generally related to the faulting.

Drilling encountered elevated gold and arsenic values associated with quartz-carbonate-pyrite (+/- arsenopyrite) veinlets in minor shears and associated alteration zones within Yakoun volcanics. A drill hole intersected a 2 metre section which assayed 3.3 grams per tonne gold and 0.6 grams per tonne silver (Assessment Report 8225).

Geological mapping and geochemical surveys by JMT Services Corp. and Chevron Canada Ltd. in 1977 and 1978 led to the discovery of the Gumbo Zone. Four diamond drill holes were drilled by the joint venture in 1980. Misty Mountain Gold Ltd. flew airborne radiometrics, resistivity and magnetometer surveys over the showing in 1995. A VLF geophysical survey was completed over the showing on behalf of the owner, Sam Courte, in 1997 to locate a potentially gold-bearing structure at depth.
