The Louis occurrence is located about 45 kilometres south-southeast of the community of Dease Lake.

The area is underlain by the contact of volcanic rock, probably of the Middle Triassic Stuhini Group, and intrusive rock, probably of the Middle Jurassic Three Sisters Plutonic Suite. The mainly andesitic and basaltic volcanic rocks are cut by granitic dikes and are locally altered and migmatized. Chalcopyrite was found disseminated in a zone of migmatite between intrusive and volcanic rocks.

In 1972, the owner of the Louise claims, L. Elliot, took 300 soil samples. No other work is documented.
