Oct 18, 2011 (A Wilson) - The skarn lies within a succession of paragneisses of probable volcanic origin and calcitic and dolomitic marbles in the hanging wall of the northeastern lobe of a tonalite intrusion. The skarn zone is bounded to the south by a small intrusive body of diorite and is cut by dikes of diorite and tonalite. All rock units strike northeasterly and dip steeply to the southeast.

Oct 18, 2011 (A Wilson) - Mineralization consists of streaks and disseminations of magnetite in an orebody 1300 feet long and 250 feet wide. A sample collected in 1913 contained 42.00% Fe, 0.01% TiO2, 0.152% P2O5, 7.75% CaO, 2.00% MgO and 12.53% SiO2. The distribution of magnetite in the ore zone is erratic, but the deposit possesses a high-grade central portion, with the intensity of mineralization gradually decreasing towards the margins of the deposit.
