The Branch 1 Road graphite occurrence is located 800 metres south of South Caribou Lake, approximately 17 kilometres east-southeast 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, a quartz-biotite schist and marble hosts 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 2014, a continuous chip sample over 48 metres yielded 3.32 per cent graphite (Assessment Report 34974). The following year, rock samples yielded from 1.87 to 5.06 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.
