In pegmatite dyke cutting amphibolite, pyroxenite and gneiss.

"The deposit was opened on the farm of R. Thompson in 1925 by Feldspar Mines Corporation. It was operated until 1925 and again in 1927. Production amounted to 2463 t of feldspar.

The main pit is 55 m long and 6-7 m wide with a 9-m face. There are two smalller pits: one pit located 55 m to the south-west is 9 m by 6 m and 3.5 m deep and the other 15 m west of this is 24.5 m by 6 m and 3-3.5 m deep."
