Toronto-based Caledonia Mining (CAL-T) has released results from the second round of drilling at its Kadola West copper-cobalt prospect in the southern extension of the Zambian copper belt.
Six of eight shallow reverse-circulation holes, drilled to test the 1500-metre-long southeastern extension of the soil geochemical anomaly at Kadola West, have intersected significant copper and cobalt mineralization.
An additional six holes, drilled in a portion of the anomaly that had lower geochemical values, did not intersect significant mineralization. Caledonia officials believe this part of the anomaly represents a barren zone between two major blocks of mineralization which have been offset by faulting.
Results from the latest holes include: 40 metres of 0.93% copper and 0.1% cobalt in hole 16; 10 metres of 0.35% copper and 0.02% cobalt in hole 17; 8 metres of 0.27% copper and 0.03% cobalt in hole 18; 10 metres of 0.78% copper and 0.02% cobalt in hole 19; 5 metres of 0.23% copper and 0.4% cobalt in hole 21; and 7 metres of 0.25% copper and 0.01% cobalt in hole 33.
A program of expanded geochemical soil sampling and ground magnetic surveys will begin shortly, in preparation for additional drilling later this year.
Caledonia is investigating the potential for an open-pit, heap-leach operation using acid or bioleaching, followed by solvent
extraction-electrowinning. In addition, drilling will be applied to geochemical and geophysical targets in the vicinity of Kadola West.
