Aug 02, 2011 (A Wilson) - At the main pit, there is an allanite-rich zone exposed in the south wall of the cut. The zone has an exposed length of 12 feet and a maximum thickness of about 4 feet. The zone is irregular and grades into allanite poor granite gneiss at either end.

Aug 02, 2011 (A Wilson) - Allanite forms up to 5% of the mineralogy in the pits and trenches on the property. Zircon, titanite, magnetite and garnet also were found as accessory minerals in the granite and pegmatite. Lath shaped allanite crystals up to 1 inch in length make up 10-15% of the rock at the main pit. A grab sample (R-77-63-2) collected from the main trench by the OGS assayed 0.09% U3O8 and 0.42% Th. Allanite occurs as black, vitreous, bladed crystals associated with sphene, hornblende and irregular hematite-stained fractures.
