Mineral location - sodalite. 1906 : opened by T. Morrisson and 130 tons shipped to England as a decorative stone. 1960 : operated by C. Bosiak then P. Rasmussen for mineral specimens, in conjunction with a rock shop. The open-cut was about 200 ft long with a 5-10 ft face and there was a second pit at the foot of the hill. The former is now largely filled with loose rock and the north pit is the main working. The irregular distribution of the sodalite made it difficult to quarry but the use of explosives has made the removal of blocks an impossibility.

A biotite-nepheline-albite gneiss is cut by a small body of nepheline-albite pegmatite. Sodalite has developed along joints and fractures in the pegmatite and gneiss. Locally, the sodalite has a pegmatitic texture and ranges in size from fine veinlets to groups of crystals several cms wide. The sodalite is distributed very irregularly, but the best development is along fractures where it has spread out for several tens of cms in pegmatitic patches, along the gneissosity. Sodalite is associated with hydronephelite, cancrinite and green gieseckite and the alteration zones have a maximum width of about 3 ft. Apatite-biotite -calcite marble occurs at the E side of the S end of the old main working.
