Aim-listed Arc Minerals has commenced an initial 7 500 m drilling programme at its Zamsort/Zaco copper projects located in the Zambian Copperbelt, adjacent to world-class operating copper mines.
Zambia – During 2018, Arc Minerals conducted a comprehensive high-resolution airborne geophysical survey over its Zamsort and Zaco projects. The licenses cover in excess of 850 km² and host a large number of targets in addition to the Kalaba copper-cobalt prospect.
Arc Minerals has appointed a local drilling contractor with significant experience in the Copperbelt and two diamond drill rigs have commenced drilling.
The drilling programme is designed to test the company’s large highest-priority targets – the Cheyeza anomaly – as well as the Lumbeta and Muswema targets in addition to other targets generated through the comprehensive geophysical and soil sampling programme.
"Over the past year our technical team with the help of highly experienced external exploration consultants have completed a detailed geophysical survey and extensive soil sampling programme which has yielded some excellent results indicating that we may have a number of high-potential prospects within our Zamsort licence, says Arc Minerals executive chairman Nick von Schirnding.
The completion of the airborne geophysical survey and broad spaced soil geochemical programme by Xcalibur Airborne Geophysics last year, which covered the entire license areas and comprised 5 218 line-kilometres, resulted in the identification of 12 anomalous target areas within the Zamsort-Zaco license areas.
Since then, further infill soil sampling over the 10 km x 8 km Cheyeza region has been completed using an Olympus Vanta XRF analyser. Over 6 000 of the 35 000 samples collected over the licence area have already been analysed, adding a further target anomaly (Cheyeza Central).
Of particular interest is a 3 km by 0.8 km area at Cheyeza East where up to 2 792 ppm copper in the soils has been identified.
Arc Minerals mobilised its drill rigs after receiving the results of its first infill soil geochemistry programme which generated a large number of drilling targets from the data and geological models.
The infill soil geochemical programme is continuing and at present the exploration team are collecting and analysing soil samples over the Lumbeta target area and thereafter will continue to cover the remaining target areas identified from last year’s exploratory programmes.
