Gold One upbeat on Modder East drilling - Miningmx

Nov 10, 2010  The shoreline represented the highest grade area of the Buckshot Pyrite Leader Zone (BPLZ) of the Black Reef. In addition to the BPLZ intersection, the underlying Channel Facies in borehole DD69 intersected 6.0 grams per tonne over a channel thickness of 427cm, confirming the high grade channel intersection obtained in DD66.
