May 07, 2013 (A Wilson) - The stone is irregularly jointed and is pure white in colour at the southernmost part of the property. The band of stone was 200 feet wide and was flanked on both sides by very siliceous dolomite. The stone was described as being very coarse-grained white dolomitic marble, both pure and impure. The pure stone was quarried for use as dimension stone and for making lime. The dolomite marble strikes to the north across the property and dips 55ºE. The high purity stone occupies a zone about 75 m wide and is banded on either side by chemically impure dolomitic marble containing quartz and masses of amphibolite. The Chromasco magnesium deposit is of a band of very pure dolomitic marble that occurs within a completely deformed sequence of interlayered dolomitic and calcitic marble, siliceous marble, quartzo-feldspathic and amphibolitic metasediments, and metavolcanics. These supracrustal rocks have been invaded by a variety of intrusive rocks, including gabbro and granite, which form large plutons to the east and southwest of the marble deposit. The marble band strikes in a northerly direction and dips at about 50 degrees to the east. It is medium to coarse-grained (2-5 mm), well layered, and varies from white to pink to grey in colour. Minor amounts of impurities including white mica, calc-silicate minerals, and graphite, generally occur as sparse, scattered, fine grains. Lenses of calc-silicate rock occur locally within the marble deposit, necessitating selective mining in some places. Calcite veins and potassic alteration along fractures also constitute local quality control problems.

May 07, 2013 (A Wilson) - A grab sample collected by Goudge (sample 127)assayed 0.20% SiO2, 0.10% Fe2O3, tr Al2O3, 0.04 Ca3(PO4)2, 55.82 CaCO3 and 44.00% MgCO3. The deposit had an indicated length of 3500 ft and an average width of 250 ft. The indicated tonnage was originally 72,800 tons per vertical foot.
