The Molehill occurrence is in a southeast-trending valley, northwest of Kemess Creek and approximately 3.5 kilometres north-northeast of Kemess Lake, about 190 kilometres north-northwest of the community of Germansen Landing.

The Toodoggone district 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 covering an area of 90 by 25 kilometres. The basement rocks are Proterozoic metasedimentary equivalents of the Hadrynian Ingenika Group. These rocks are unconformably overlain by volcanic and sedimentary units of the Devonian to Permian Asitka Group, which are in turn overlain by Upper Triassic basaltic to andesitic flows, volcaniclastics and minor limestone of the Stuhini Group. Volcaniclastic rocks of the Lower Jurassic Hazelton Group and rhyolitic to dacitic flows, intrusions and volcaniclastics of the Lower Jurassic Toodoggone Formation (Hazelton Group) overlie the Stuhini Group. Further to the west, nonmarine sediments of the Cretaceous Sustut Group overlie the volcanic strata and form the western margin of the district.

The Early Jurassic Black Lake Suite, of quartz monzonitic to granodioritic composition, has intruded the older strata in the central and eastern parts of the region and forms the eastern margin of the Toodoggone district. Within the district, syenomonzonitic and quartz feldspar porphyritic dikes may be feeders to the Toodoggone Formation.

Locally, the area is mainly underlain by andesitic to basaltic volcanics of the Stuhini Group, with the exception of the eastern regions, which are underlain by fragmental tuffs of the Toodoggone Formation. Lower Jurassic stocks, dikes and possible sills of quartz monzonite to quartz diorite composition have intruded the Stuhini Group. See Kemess North occurrence (094E 021) occurrence for a detailed description of the regional geology.

Locally, a chlorite-sericite altered ‘Sovereign’ intrusive (monzonite) hosts pyrite, chalcopyrite, malachite and azurite mineralization associated with a north-northwest striking structural zone. In 2006, two grab samples (PG-02 and OG-04) yielded 0.268 and 0.182 per cent copper with 25.4 and 11.3 grams per tonne silver, respectively, while a 1.4-metre chip sample (PGC-03) assayed 0.11 gram per tonne gold and 5.7 grams per tonne silver (Assessment Report 29049).

The area has been historically explored in conjunction with the nearby Kemess North developed prospect (094E 021) located 2.3 kilometres west-northwest and the Kemess South past-producing mine (094E 094) located 5.3 kilometres south.

During 1966 through 1971, Kennco Explorations Ltd. completed programs of geochemical sampling and geological mapping on the area immediately west as the Kemess 1-100 claims. In 1975 and 1976, Getty Mines Ltd. examined the property and completed programs of soil sampling and geological mapping on the area immediately west.

During 1986 through 1989, El Condor Resources Ltd. completed programs of rock and soil sampling, geological mapping, trenching and a 14.1 line kilometre ground magnetic survey on the area immediately west as the New Kemess 1-2 claims. In 1990 and 1991, El Condor Resources Ltd. conducted programs of geological mapping, geochemical sampling and a 201.0 line kilometre induced polarization survey on the area as part of the Kemess property.

During 2000 through 2011, Northgate Minerals Corp. completed programs of geological mapping, geochemical sampling, geophysical surveys and diamond drilling on the area as part of the Kemess property. The occurrence was discovered in 2006 and a program of trenching and rock and soil sampling was conducted.

During 2013 through 2017, AuRico Gold Inc. examined the area as part of the Kemess and Kemess East properties.
