The Barnes 7 occurrence is located on a south- facing slope west of Barnes Creek and approximately 1.5 kilometres northeast of Holmes Lake.

The area is underlain by mudstone, siltstone, shale, phyllite, marble, fine clastic sedimentary rocks and volcanic rocks of the Upper Triassic to Lower Jurassic Nicola Group and Devonian to Triassic Harper Ranch Group. These have been intruded by quartz diorite dikes of the Jurassic Nelson Intrusions and Cretaceous Whatshan Batholith.

Locally, fractured and altered feldspar porphyry hosts quartz veining, up to 15 centimetres wide, with chalcopyrite, pyrite and trace tetrahedrite and galena mineralization. Small amounts of fine-grained, fracture controlled, visible gold are also reported. Alteration minerals include quartz, carbonate, sericite and malachite. The veins variably dip to the east with a northerly strike and trend parallel to the Beavan Fault to the east.

In 2005, two chip samples (23051 and 23052) of vein material from trench 31N yielded values up to 16.4 grams per tonne gold and 282 grams per tonne silver over 0.15 metre, while a 2.7 metre chip sample of fractured feldspar porphyry adjacent to the vein assayed 0.207 gram per tonne gold (Assessment Report 28197). Sampling of a malachite stained quartz vein from trench 32N, located a short distance north, yielded up to 14.9 grams per tonne gold and 594 grams per tonne silver (Sample 23068; Assessment Report 28197).

In 2015, a rock sample (706) assayed 8.2 grams per tonne gold and 52.4 grams per tonne silver (Assessment Report 36024).

During 2003 through 2005, Columbia Yukon Explorations completed programs of rock and soil sampling, geological mapping and trenching on the area as the Barnes claims. In 2015 and 2016, programs of geochemical sampling and geological mapping were completed on the area as the Lode Star property.
