The ground biogeochemical survey consisted of collecting up to ~98 samples of tree bark and needles. The survey area has been selected based on previous geological investigations of a granitic intrusion and the general trend of the exposed pegmatites in the blast pits to the north. The results of sample assays show lithium values less than 0.5 ppm Li which is below the laboratories method detection limit. Cesium values are in the range of 0.062 ppm to 1.66 ppm.

Other rare metals such as niobium and tantalum are also below the laboratory’s method detection limit.

Geology

The property is underlain by similar geological rocks to the Rose Lithium deposit and are comprised of the Archean Lower- Eastmain Group, constituted of volcano-sedimentary formational units and ultramafic to felsic intrusives. Gabbros, pyroxenites, and diorites cut across the Property geology. Pegmatites occur as irregular but generally continuous lenses within biotite schists. These felsic rocks intruded paragneiss, sandstone and conglomerate. Younger rocks of the property are represented by a Proterozoic diabase dyke.
