The Nor occurrence is located approximately 2 kilometres east of Thutade Lake and 3 kilometres west of Kemess Creek, about 190 kilometres northwest of the community of Germansen Landing.
The area is underlain by Upper Triassic Stuhini Group volcanic flows, fragmental rocks and lesser sedimentary rocks. To the north, these rocks are intruded by the Lower Jurassic Black Lake granitic stock. To the south, clastics of the Mid- to Upper Cretaceous Sustut Group overlie the older rocks.
In the Nor showing area, local shears strike northwest and are typically silicified and contain sericite and pyrophyllite. A granodiorite mass located on the Nor 2 and 3 claims contains disseminated accessory magnetite. Traces of pyrite and chalcopyrite are also present. Diorite and dacite float material contain minor sulphide disseminations.
The Nor claims were staked to cover reconnaissance VLF-EM responses obtained over favourable geological structures on the east side of Thutade Lake in the southern part of the Toodoggone Gold Camp. Work on the property in 1986 consisted of a reconnaissance geological and geochemical survey. In 1989, a total of 14.4 line kilometres of induced polarization and resistivity surveys was done over portions of the Nor 4 and 7 claims on behalf of Cambridge Resources Ltd.
In 1991-92, the Nor and Cooke options, together with claims wholly-owned by Rio Algom Exploration Inc., form a contiguous property and adjoin the Kemess South Joint Venture property to the south. Work in 1991 consisted of geological mapping, soil geochemical sampling, induced polarization and magnetics surveying and diamond drilling. The purpose of this work was to delineate the westward extension of the adjacent Kemess South deposit and to test the undrilled portions of the Nor, Cooke, and Rio zones (094D 133), outlined in 1991. A total of 4519.8 metres of NQ wireline diamond drilling was completed in 18 holes from 18 setups. Six holes (92-24, 92-27 to 92-31) totalling 1184.7 metres were drilled to test the northern and western portions of the Cooke zone. The Cooke zone is predominantly underlain by phyllic-altered volcaniclastic rocks which are invaded by abundant dikes of feldspar porphyry monzodiorite, diorite and gabbro. Partially assimilated xenoliths of andesite and zones of hybrid intrusive-volcanic are common. Phyllic alteration is typically strong to intense (80 per cent sericite-quartz-pyrite) with ubiquitous disseminated pyrite averaging 1 per cent in the volcanic rocks. No significant, geochemically anomalous zones of copper or gold were intersected. Given the preponderance of intrusive bodies coupled with intensive alteration and assimilation of the volcanic rocks, it is likely that the Cooke zone is proximal to a significant pluton. Widely spaced drilling within and around the Nor, Cooke and Rio zones outlined in 1991, failed to locate significant copper-gold mineralization. As a result, all of the near-surface targets identified by geophysical surveys have been adequately tested by surface mapping and diamond drilling (Assessment Report 22886).
