It is colourless to silvery white with shiny surfaces, and like all micas it splits into thin flakes along its one perfect cleavage.

| All three drill holes intersected highly altered mafic volcanic rocks containing ankerite, sericite, fuchsite disseminated pyrite and quartz veins, similar to the lithologies hosting gold in the McEnaney Mine. All three holes intersected intensely altered and sheared zones ranging from 17 to 32 m wide (core length) containing ankerite, sericite, fuchsite disseminated pyrite and quartz veins, suggesting that the mineralized zones may have been intersected. Gold mineralization occurs within a broad deformation - alteration zone (quartz, ankerite, sericite, fuchsite, pyrite) termed the Thibault Horizon, and is located approximately 1 km to the south of the Golden River Deformation Zone. |
