Drilling at the Nama copper-cobalt project in northern Zambia continues to outline additional mineralization.
Operator Caledonia Mining (CAL-T) is investigating two anomalies, one of which, Anomaly A, has been subjected to nine drill holes. All nine returned mineralized intersections, with five cutting multiple zones of mineralization. Individual zones range in width from 7 to 37 metres, with grades estimated at 0.016-0.057% cobalt and 0.03-0.32% copper.
Eight of the nine holes were drilled 50-100 metres beyond the limits of known mineralization, and drilling is continuing.
At another prospect, Anomaly D, a tabular body of mineralization, measuring 2 km long and 0.5-1.3 km wide, has been outlined by 12 drill holes. Recent results show thicknesses of 7-14 metres and grades of 0.02-0.05% cobalt.
About 20 more holes will be drilled at this prospect, and drilling is also planned for a third prospect, Anomaly E.
At the Kadola property, also in the Zambian Copperbelt, consulting firm Watts, Griffis & McOuat has conducted a preliminary resource calculation on the Kadola West copper-cobalt prospect. The inferred resource is 74 million tonnes grading 0.51% copper and 0.017% cobalt. The acid-soluble grade, representing the concentration of metal recoverable by a leach process, is 0.44% copper and 0.01% cobalt.
At its Eureka prospect, also on the Kadola property, the company has drilled coincident geophysical and geochemical anomalies. Copper and gold mineralization was found in four of seven drill holes, which showed grades of 0.33 to 5.5% copper and 0.3 to 2.2 grams gold per tonne, over widths of 1 to 26 metres. The most recent drill hole intersected 50 metres with average grades of 0.54% copper and 0.84 gram gold per tonne.
