Aug 01, 2013 (A Wilson) - The host of the ore body is a dark green hornblende gneiss. It is composed of large hornblende crystals and elliptical pods of felsic material (plagioclase and quartz). To the east of the gabbro is a wide formation of hornblende (+garnet) schist. To the west of the gabbro is a formation of granite gneiss. All units are cross cut by diabase and pegmatite dikes. The main ore zone has been folded.

Aug 01, 2013 (A Wilson) - Diamond drilling intersected three high-grade sections totalling between 35 and 50% soluble iron with two low grade sections of disseminated magnetite. The total thickness is about 41 m containing less than 35% soluble iron. The high grade samples commonly contain between 10 and 15% Ti and 0.01% Ph.
