Oct 18, 2011 (A Wilson) - The deposit consists of four separate deposits that occupy several small calc-silicate skarn zones within a calcitic marble that lies structurally above a tonalite intrusion. The marble is cut by several small diorite intrusions and narrow granitic dikes. All units strike northeasterly and dip 70-85° SE. The skarn zones consist of massive, fine- to coarse-grained, dark coloured rock composed of carbonate, clinopyroxene, epidote, hornblende, garnet and minor biotite.
