Jul 25, 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.

Aug 19, 2013 (A Wilson) - The North Zone is overlain by peridotite and is underlain by peridotite and/or intrusive feldspar pophyritic aplite. The strata are relatively flat lying and stratigraphy is difficult to determine. The talc-magnesite encountered in the 2009 North Zone holes is generally finer-grained with less evidence of cumulate textures than in the South Zone, and typically contains a lower abundance of magnesite veins. The talc-magnesite is underlain by complexly altered ultramafic rocks, with variable amounts of chlorite, serpentine, talc and magnesite, possibly including other thin intervals of talc-magnesite that would be economic if present in larger amounts. The ultramafic rocks in this area are cut by a suite of thin, felsic to intermediate, plagioclase porphyritic dikes.

Aug 19, 2013 (A Wilson) - The zone is approximately 30 m thick. Allerston North Zone: estimated tonnage 6.3 million tonnes (S028, p. 23): average composition 33.3% magnesite, 46% talc, 1.9% dolomite, 7% chlorite, 8.5% iron oxide. An additional 12,987,000 tons is estimated from geophysical work and limited trenching (R219 p.111) Assays from the 2009 drilling completed by General Magnesium returned 20.66% magnesite and 53.8% talc over 2.9 m in GMWN09-01; 32.91% magnesite and 49.66% talc over 2.66 m in GMWN09-02; and 47.25% magnesite and 35.78% talc over 3.0 m in GMWN09-04.
