Dec 17, 2010 (A Wilson) - The main magnesite deposit is either a large carbonate-altered dunitic komatiite body or a series of dunitic or peridotitic komatiite flows. Poorly preserved spinifex textures and the fact that the ultramafic sequence occurs on the southwest flank of the Shaw Dome indicate that the stratigraphic tops are probably to the south. At the east end of the property, the iron formation is almost pure quartzite, which in places has been recrystallized to quartz veins that cross cut bedding. Locally, iron formation displays beds of jasper or reddish-coloured volcanic fragments and carbonate. At the west end of the property the iron formation is a thin carbonaceous pyritic tuff. The volcanic rocks that overlie the magnesite-talc zone are massive andesite, andesite breccia and minor dacite and quartz-crystal lapilli tuff. Locally, units are highly carbonate altered. This unit overlies the argillaceous tuff. The underlying basalt is massive and dark green in colour and displays vague outlines of pillows.

Sep 06, 2012 (A Wilson) - Nickel values from the magnesite concentrate produced from the Pamour bulk sample returned values ranging from 0.073% Ni to 0.14% Ni. A typical analysis of dead-burned MgO product is given as: MgO 92.5 percent, Fe2O3 6.0-6.5 percent, SiO2 1.0 percent, CaO Less than 0.2 percent, Miscellaneous Less than 0.5 percent Boron 10 ppm. By-product talc also produced by flotation is given as: Total MgO 31.61 percent, SiO2 62.64 percent, Total Fe* 0.35 percent, LOI 5.27 percent, CaO Nil, Al2O3 Nil.
