The Falls occurrence is situated on the north fork of Six Mile Creek, approximately 44 kilometres northwest of the town of Mackenzie, in the Omineca Mining Division.

The Falls occurrence lies within Ancestral North America terrane sediments, possibly within the Upper Proterozoic Misinchinka Group. As recorded in the 1904 Department of Mines Annual Report "the mica appears to be very good grade and the surface showing is said to be very encouraging". A more detailed description is not available.
