Sep 18, 2015 (A Wilson) - The magnetite-bearing zone contains coarse-grained hornblende, pyroxene, scapolite and calcite developed in granitic gneiss, the foliation of which strikes northeasterly and dips steeply southeasterly. Crystalline limestone is exposed on a hill to the northwest of the pits. Magnetite in scattered grains and lenses impregnates the rock, and coarsely crystalline magnetite occupies vuggy parts. In polished section the magnetite-rich material showed a mosaic of coarse crystals of magnetite, magnetite with vermicular and rod-like intergrowths possibly of hematite or ilmenite, a few grains of hematite, sparsely disseminated pyrite and gangue.

Sep 18, 2015 (A Wilson) - Chemical analyses of ore samples reported in 1899 showed an iron content of 59.55 to 62.95 per cent, negligible phosphorus and titanium, and 6.59 % insoluble matter. An experimental shipment of the magnetite is said to have been made. Four small dumps containing an estimated 150 tons of ore-grade material remain.
