About Engineer Gold Mines Ltd.

The Engineer Gold Project encompasses an area of 18,319 hectares and is currently subdivided into three areas: the Engineer Gold Mine, Tag Property and Wann River. Recent exploration has identified a small, high-grade historical gold mineral resource at the historical underground Engineer Mine (see Company website for NI-43101 report), a small gold-silver historical mineral resource on the Tag Property, numerous high-grade vein and shear-hosted bulk-tonnage gold exploration targets and a small, high-grade gold production opportunity. Both the resources are epithermal-style systems with additional epithermal targets evident on the Project, including the Happy Sullivan. Wann River constitutes an orogenic gold target associated with the prolific Llewellyn fault, and has returned significant gold silver results including a grab sample yielding 263 g/t gold and 1350 g/t silver in 2010 from the Lum showing, one of the many local BC Minfile showings.
