The Mess 5 occurrence is located at an elevation of approximately 1850 metres on a northeast-trending ridge, approximately 5 kilometres northwest of the north end of Fredrikson Lake, and about 179 kilometres north-northwest of the community of Germansen Landing.

The Toodoggone Gold Camp lies within the eastern margin of the Intermontane Belt and is underlain by a northwest trending belt of Paleozoic to Paleogene sediments, volcanics and intrusions. Regionally, the area is situated within a Mesozoic volcanic arc assemblage bounded to the east by the Omineca Belt and to the west and southwest by the Sustut and Bowser basins. Devonian to Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region and are commonly in thrust contact with Upper Triassic Stuhini Group marine sedimentary and volcanic rocks, andesite flows and pyroclastic rocks. These units have been intruded by the granodiorite to quartz monzonite of the Early Jurassic Black Lake Suite and are in turn unconformably overlain by or faulted against dacitic volcanics and volcaniclastics of the Lower Jurassic Toodoggone Formation (Hazelton Group).

The dominant structures in the area are steeply dipping faults that define a prominent regional northwest structural fabric trending 140 to 170 degrees. High angle, northeast-striking faults (approximately 060 degrees) appear to truncate and displace northwest-striking faults. Collectively these faults form a boundary for variably rotated and tilted blocks underlain by monoclinal strata. A major structural zone associated with the Saunders Creek regional fault cuts diagonally through the area, striking northwest.

Locally, a quartz vein hosts pyrite and chalcopyrite mineralization. The area is mapped as being underlain by marine sedimentary and volcanic rocks of the Stuhini Group and limestone of the Asitka Group near their fault-blocked contact with undivided intrusive rocks of the Black Lake Suite.

In 2004, a rock sample (165771) assayed 3.74 grams per tonne gold, 5.1 grams per tonne silver and 0.944 per cent copper, whereas other samples (165769 and 165722) yielded up to 0.16 gram per tonne gold, 9.0 grams per tonne silver and greater than 1.0 per cent copper (Assessment Report 27636).

During 2003 through 2006, Stealth Minerals Ltd. completed programs of prospecting, geochemical (rock, silt and soil) sampling and geological mapping in the area as the Fog-Mess property.
