The Nek-1 occurrence is located at an elevation of approximately 1500 metres on a south-southwest facing slope approximately 500 metres east of Duncan Lake, about 191 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, at the Nek-1 showing as defined by diamond drilling, Asitka Group sediments and volcanics have been intruded by monzonite masses with mineralized skarn or hornfelsed zones being formed near the contacts. In 2003, diamond drilling yielded up to 2.98 grams per tonne gold over 1.9 metres in hole CD-10, whereas other sections yielded up to 0.340 per cent copper (Assessment Report 27365). In 2012, diamond drilling yielded intercepts including 0.224 gram per tonne gold, 0.028 per cent copper and 0.003 per cent molybdenum over 20.8 metres and 0.689 gram per tonne gold over 3 metres in hole KN-11-15 (Assessment Report 33320). Mineralization is inferred to be chalcopyrite and molybdenite from drill core assay results.
The area has been historically explored in conjunction with the nearby Kemess North deposit (094E 021) located 2.3 kilometres northeast, and the Kemess South deposit (094E 094) located 5 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 apart of the Kemess property. In 2003, two diamond-drill holes (CD-10 and CD-19) were completed on the Nek-1 occurrence. During 2013 through 2017, AuRico Gold Inc. examined the area as part of the Kemess and Kemess East properties. In 2012, AuRico Gold Inc. completed four diamond-drill holes, totalling 597.0 metres on the Kemess property, with two holes being located near the Nek-1 occurrence.
