In syenite or granitic pegmatite cutting biotite gneiss and garnet-biotite gneiss. The pegmatite is composed of peristerite, microcline, quartz, and abundant pyroxene. Fractures are filled with veinlets containing fluorite, calcite, and pyrite.


"The deposit was discovered by E.T. Hogan and was explored for uranium mineralization by Stratmat Limited in 1953 and by Halo Uranium Mines Limited in 1955-56. Underground development consists of two adits and a shaft sunk from one of the adits. The deposit is located on the northwest side of Hall Lake; No. 1 adit is near the shore of the lake and No. 2 adit is 300 m northwest of it. The property is held by Rare Earth Resources Limited."
