Two dykes occur on the property, one a dyke of pink spar about 30
feet wide carrying considerable black mica, and the other a dyke of white
spar about 15 feet wide. Work was confined principally to a small opencut
on the former deposit, and about 25 cars are reported to have been
shipped. (Spence 1932)

Gadolinite and euxenite are found in a pegmatite dike cutting between metamorphic pyroxenite and gneissic granite. The dike is zoned with masses of quartz and microcline, rarely as much as 10 inches in diameter, either separately or as intergrowths of the two in the centre. These are flanked by zones carrying, plagioclase, and small rusty zones in which small crystals of euxenite, allanite and gadolinte occur sparsely. Greenish flakes of mica and some pyrite, pyrrhotite and chalcopyrite occur sporadically through the outer zones of the dike.
