The Mosquito graphite occurrence is located north west of Mosquito Creek, approximately 16 kilometres south west of the town of Nakusp.

The area is underlain by calcareous and epiclastic metasedimentary rocks of the Devonian to Carboniferous Chase and Silver Creek formations of the Proterozoic to Paleozoic Monashee Complex.

Locally, quartz-biotite-muscovite-garnet schist, biotite-garnet±muscovite±silliminite schist and marble host coarse- grained flake graphite. Graphite occurs as bright blue-black flakes disseminated throughout and oriented parallel to the foliation plane. Flake sizes generally range from less than 0.1 millimetre to greater than 1 millimetre.

In 2012, seventeen grab samples from within the Mosquito claim block returned average values of 2.54 per cent graphite (Noram Ventures News Release December 14, 2012). In 2015, rock sampling yielded from 2.6 to 4.75 per cent graphite, while sampling to the north east yielded from 2.78 to 7.56 per cent graphite (Assessment Report 35894).

In 1980, Shamcrock Construction completed an induced polarization and resistivity survey on the area as the Red Fisher claims. During 2012 through 2015, Noram Ventures Inc. completed programs of rock sampling, geological mapping, eight diamond drill holes, totalling 1294.8 metres, and a combined airborne magnetic and electromagnetic survey on the area as the Jumbo Graphite property.
