The MAC Lithium Project comprises four contiguous claims that cover approximately 4,300 hectares and is located 80 kilometres north of Yellowknife immediately west of the Winter Road. The claims host numerous documented pegmatites both north and south of Thistlethwaite Lake which transects the project (Figure 1).

The Consolidated Mining and Smelting Company of Canada undertook basic surveying across part of the MAC Lithium Project between 1938 and 1940 which identified numerous pegmatite dykes in quartz-mica schists of the Yellowknife Group. A historical description found in a GSC publication from 1944 of a swarm of pegmatite dykes immediately southwest of the MAC Project documents tantalite and beryl as being present within the pegmatites.Recent details of Trinex exploration activities on the project can be found in the following ASX announcements:
