The Valley of the Dolls occurrence is located on the north side of a valley running between Kemess and Duncan lakes, approximately 1.1 kilometres northwest of Kemess Lake, about 188 kilometres 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 Neoproterozoic 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.
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.
Locally, Asitka Group sediments contain garnet-diopside skarn zones with narrow, approximately 1-centimetre-wide, quartz veins and veinlets hosting sphalerite, minor chalcopyrite and rare visible gold. In 2003, diamond drilling yielded intercepts of 7.4 grams per tonne gold over 0.8 metre in hole KC-03-03; 0.281 per cent copper and 1.16 grams per tonne gold over 0.83 metre in hole KC-03-04, and 0.18 gram per tonne gold over 4.5 metres in hole KC-03-09 (Assessment Report 27365). Also, at this time, hole DR-03-01 intersected 11.75 metres of garnet-diopside skarn at a downhole depth of 312 metres that graded 0.8 per cent copper, 2.24 per cent zinc and 12.7 grams per tonne silver (Exploration and Mining in British Columbia 2003, page 19).
The area has been historically explored in conjunction with the nearby Kemess North developed prospect (094E 021) and the Kemess South past-producing mine (094E 094).
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 apart of the Kemess property. In 1999, Royal Oak Mines Inc. completed a series of 16.0 line kilometre ground geophysical surveys on the area.
During 2000 through 2011, Northgate Minerals Corp. examined the area as part of the Kemess property. In 2003, seven diamond-drill holes were completed on the area. During 2013 through 2017, AuRico Gold Inc. examined the area as part of the Kemess and Kemess East properties.
