The Lynne occurrence lies within the Lynne claims (ca. 1973) which are located 5.9 kilometres northeast of the Stikine River, about 109 kilometres east of the village of Iskut. The moderately dissected rolling terrain is typical of the Spatsizi Plateau.

The property lies in the Stikine arch which is bounded to the south by the Bowser Basin. The general east trend of faulting and folding along the Stikine arch contrasts with the dominantly northwest trend found in the Stikine Terrane. Mapping by the Geological Survey of Canada defines the underlying lithology as "polydeformed Mississippian to Permian chloritic schist, chert and amphibolite and massive Upper Triassic Stuhini Group porphyritic volcanics" (Open File 1005; Paper 84-1). Extensive plutonism during the Late Triassic emplaced dioritic, monzodioritic, granodioritic, and granitic phases of the informally named Stikine batholith which is likely related to the Late Triassic to Late Jurassic Hotailuh batholith. Paleozoic units are regionally metamorphosed to amphibolite grade and Lower Mesozoic rocks to lower greenschist grade.

The Lynne showing comprises sparse molybdenite, copper sulphides (mineral type not stated but assumed to be chalcopyrite), and pyrite in quartz veins hosted by a roof pendant of amphibolite in gneissic diorite of the Stikine batholith. Potassium-feldspar, epidote, and calcite veins intrude amphibolite and argillite units marginal to the batholith. A second minor occurrence of copper mineralization, in quartz veins hosted by argillite, is located in the southwest corner of the property. Analysis of mineralized bedrock was not reported; overall the mineralization was described as minor and of non-economic potential.

The property was briefly explored from 1973 to 1974, during which time mapping, soil sampling, induced polarization and ground magnetic surveys were conducted.
