Geology Comments

Jul 26, 2007 (A Wilson) - Foliations trend NE (10-60°) and dip 10 -30°N. Locally, foliations trend NW (with dips to SW at 10-60°) or NE to E-W with dips 10-50° N or S, indicating a series of gentle folds which may be part of a large structure. A series of gently undulating folds occur in the west central part of the property. There is a possibility that thrusting could account for the repeated sequence of talc-magnesite, felsic to intermediate volcanics and iron formation in the South Zone area. Breccia and shear zones are noted both in the field and in drill core, especially in the graphite iron formation and mafic metavolcanics near the contacts.

Lithology Comments

Jul 26, 2007 (A Wilson) - The South Zone is overlain by andesitic tuff, chert and intermediate tuff and is underlain by chlorite-carbonate schist (peridotitic komatiite) and magnetite-jasper iron formation. The strata are relatively flat lying and stratigraphy is difficult to determine.

Mineralization Comments

Aug 19, 2013 (A Wilson) - Initial evaluation in 1985 produced "excellent high quality talc with good potential for various industrial applications". A 1987 flotation study of five samples recovered talc with high quality brightness and whiteness (both 89-91%)-according to the author "product quality as obtained is acceptable and comparable to other commercial talc product". Pilot plant testwork was conducted on two 4.4 tonne samples from the South Zone. Approximate mineral content of the samples was estimated from the whole rock chemistry as 52-53% talc and 34-39% magnesite. Flotation products from the pilot plant samples were equal in quality to the high quality results from earlier testing. Composite samples collected by WMC Resources averaged approximately 47% talc and 37-39% magnesite. Flotation trials produced good recovery of high quality talc. The talc-magnesite mineralization is quite heterogeneous on the scale of any one drill intersection. It typically varies from well foliated on its margins to massive or banded in the interior. Banding is defined by variations in grain size, typically from medium to coarse, and occurs on the scale of 50 cm to 3 m. Banding may or may not be present in any drill intersection, and is considered to represent a relict cumulate texture. Banding is typically sub-horizontal. Veins of magnesite ± dolomite ±talc comprise 0.5 to 30% of any given interval within the body (dolomite cannot be distinguished from magnesite in hand specimen). Veins are up to 10 cm thick, although most are less than 1 cm. Veins are commonly parallel to banding/foliation, and in some instances are broken. Small amounts (0 to 2%) of magnetite are disseminated throughout the talc-magnesite.
