The Jewel Lake area is underlain by a complex of metamorphic rocks mostly of sedimentary and volcanic origin correlative with the Carboniferous or older Knob Hill Group, and a large granodiorite intrusion correlative to the Juro-Cretaceous Nelson Plutonic Rocks. Small dikes and sill-like bodies (Eocene Coryell), feeders to nearby Tertiary lavas, pervade these units.
Locally the metamorphosed volcanic and sedimentary rocks are not always distinguishable, both being fine-grained and medium or dark coloured with primary structures such as bedding and flow banding being confused with foliation or gneissosity. Generally the sedimentary rocks are brittle and quartz-rich, however, compositions vary and some biotitic varieties have the same competence as the amphibole-rich volcanic rocks. These rocks are locally called quartzites but few are true quartzites and more appropriate terms would be quartz wacke or lithic wacke. The massive character of the volcanic rocks is due to a combination of intense regional metamorphism and primary structures. Field and petrographic data indicate that at least some of the original rock formed as a result of massive accumulations of lava flows and pillow lava. Crosscutting feeder dikes and sills are significant and contribute to the massive aspect of the volcanic rocks. The metamorphosed schistose volcanic rocks are compositionally basalts. These metasedimentary and metavolcanic rocks form part of the Carboniferous (Pennsylvanian-Mississippian) or older Knob Hill Group.
Igneous intrusions in the Jewel Lake camp include a large Lower Cretaceous granodiorite pluton and a host of younger pulaskite and lamprophyre dikes. The granodiorite is correlative with Nelson Plutonic Rocks. It is a homogeneous medium-grained grey body which intrudes the metavolcanic rocks along a northwest trending contact in the southwest part of the camp. The intrusive has produced little effect in both the metavolcanic and metasedimentary rocks. Granodiorite dikes occur and are compositionally similar to the main granodiorite body and are probably offshoots from it. Pulaskite dikes are numerically most important. Several types are evident including both quartz-bearing and undersaturated types. Post-vein lamprophyre dikes as well as the pulaskite dikes are of probable Lower Tertiary age and cut all other major geological units.
The Lake View claim (Lot 1576) is located 609 metres north- northeast from the Roderick Dhu claim (Lot 598, 082ESE125). The area is underlain by north-northeast striking and east dipping metasedimentary rocks of the Carboniferous (Pennsylvanian-Mississippian) or older Anarchist Group. The rocks are schistose quartz wackes or lithic wackes and are intruded by Lower Tertiary pulaskite dikes. A quartz fissure-vein occurs in a shear/fracture zone that roughly parallels the bedding/foliation planes of the host metasedimentary rocks. The vein strikes 340 degrees with near vertical dips to the east and is finely fractured with hematite/limonite staining. Mineralization consists of galena, pyrrhotite, pyrite, chalcopyrite and telluride with prominent malachite staining and minor azurite. Vein widths range from a few centimetres to 1.5 metres. An adit follows the vein for 30 metres where it discontinuously pinches and swells.
In 1980 to 1981, the historic lake view vein was relocated and sampled. Highlighted results were reported in two grab samples grading 8.30 grams per tonne gold, and 4.59 grams per tonne gold (Caron, L. (2014-01-21): National Instrument 43-101 Technical Report on the Gold Drop Property).
In 1983, Kenar Resources Ltd. conducted a geophysics survey in the area of the Lake View occurrence. No significant results were reported.
