Sep 18, 2015 (A Wilson) - The coarse grained, white calcitic marble borders to the north of an irregular north of east trending granitic intrusive located in the north part of the property. The elongated swampy area on the north property is wholly enclosed in a carbonate sequence. Conditions for the possibility of outlining an economic zone of high-purity calcitic marble are more favourable on the north property.
