Jul 31, 2012 (A Wilson) - The rock units of the B-Zone generally strike southerly and dip moderately to the west. The migmatite forms the base of the lithologic sequence with an alteration zone towards the amphibole + biotite schist. The migmatite is most prominent on the west side of the trench and is overlain by the amphibole + biotite + quartz schist/gneiss. Locally, the amphibole + biotite + quartz schist contains garnets at the contacts with the migmatite. The amphibole + biotite + epidote schist is very weathered throughout the trench and exhibits a porphyritic texture. The deposit is associated with weathered zones developed in amphibolite and calc-silicate gneiss that are interlayered with felsite of the metasedimentary sequence. All the occurrences are located within 1 km of the eastern margin of the Jocko pluton.

Jul 31, 2012 (A Wilson) - At a mesh size of +8, vermiculite formed 6.8% for a grade of 11.5 lb per cubic foot . At a mesh size of -28, vermiculite formed 58.4% for a grade of 18 lb per cubic foot. The green vermiculite zone appears to occur as a 3 m wide band that trends for approximately 130 m along the weathering zone of the amphibole + biotite + epidote schist. The exposure of amphibole + biotite schist is too sparse in the pit to delineate a possible black vermiculite zone. Based on the proposed trend and dimensions of the vermiculite zone, the volume in the B-Zone is 390 m3 representing approximately 312 tonnes (344 short tons) vermiculite. Excellent exfoliation results were obtained from samples of both the red and black vermiculite. This material exfoliated readily retaining its size for a market grade of medium (8-14 mesh) and exhibited bulk densities superior to market requirements. For both zones, the green vermiculite exfoliated readily and mainly produced material of grade superfine (28-65 mesh) with bulk densities slightly heavier than market specifications.
