The B and C showing is situated on the north side of La Rose Creek (Granite Creek), 8.0 kilometres north-northwest of Alice Arm.

The area is underlain by a sequence of volcanic and sedimentary rocks belonging to the Upper Triassic Stuhini Group and Jurassic Hazelton Group. The sequence is folded into a north-northwest trending anticline/syncline pair and has been regionally metamorphosed to greenschist facies.

This showing comprises a 0.15 metre wide quartz vein in black siltstone (argillite) of the Stuhini Group. The siltstone is cut by numerous dikes. Mineralization comprises sparse arsenopyrite, pyrrhotite, pyrite, sphalerite and galena in a gangue of quartz and minor calcite.

In 1916, work done comprised one opencut.
