Arc Minerals, which is conducting some exploration work at its joint venture (JV) with a subsidiary of Anglo American in Zambia, has observed copper mineralisation at all targets drilled.
Two holes were drilled at the new target Nkwazhi, which is located between Cheyeza and Muswema, testing a thickened lower roan unit in this part of the basin.
The first hole intersected copper mineralisation of over 20 m at the base of the upper roan along with anomalous nickel in a marker talc-schist unit in the lower roan, below which currently no further mineralisation has been observed.
The second hole drilled 400 m away did not intersect mineralisation.
It said anomalous copper mineralisation over a downhole thickness of around 45 m was observed in the saprolite zone.
Arc said although they are waiting for results from the laboratory, the hole demonstrated the potential to significantly expand the known oxide mineralisation at Cheyeza.
"I am very encouraged by the progress made during the drilling campaign by our JV partner, Anglo American, notably the identification of a new priority target and the fact that drilling is set to continue into the wet season,” said company executive chairperson Nick von Schirnding.
“One new target in particular, close to Muswema, has moved to the top-ranked priority and exhibits alteration mineralogy comparable to known deposits within the Domes Region, with visible copper mineralisation observed in the core.”
