Shares in Arc Minerals (LSE:ARCM) sat at 2.3p on Friday after the business revealed that it has begun work on its potentially ‘game-changing’ exploration targets in northwestern Zambia.

The firm has started an exploration programme on the targets, identified by airborne geophysical work and follow-up analysis earlier this year at the copper-cobalt licence owned by Zamsort. Arc holds a 66pc equity interest in Zamsort together with a convertible loan that could increase its stake in the private company by a further 5pc.

The targets include Cheyeza West, located around 7km west of Cheyeza East where historical drilling has intersected zones of pervasive copper mineralisation. Chezea West is characterised by a historical EM anomaly that could represent a conductive unit like sulphide-rich sediment as well as well-defined radiometric anomalies.

Another target identified by the work is Lumbeta, which stretches for 11km and is associated with the crest of a fold. According to Arc, these formations can act as mineralisation traps and form high-grade deposits. Upon announcing the discoveries in February, Arc’s executive chairman Nick von Schirnding said they could represent a ‘potential game changer for the business’.

In Friday’s update, Arc said infill soil sampling has begun over the new target areas, with 1,200 samples already completed. This work will reduce the spacing between profile lines from 1km to 200m, allowing for more defined drilling of targets. Arc added that the prospects have continued to exceed expectations to date and will be drilled as soon as weather conditions permit.

Von Schirnding added: ‘I am very pleased to have completed the follow up work on the new anomalies and to have commenced the soil sampling programme early having been able to access Cheyeza West during intermittent dry periods.  As soon as weather conditions allow we shall be deploying rigs to Cheyeza West in the first instance and start our drilling programme. The Cheyeza West and Lumbeta anomalies, as highlighted on the attached map, are around 10 order of magnitudes larger than anything previously looked at in the Zamsort project area - and is a potential game changer for Arc Minerals.’

Friday’s progress comes just days after Arc revealed that it had completed the construction of a demonstration pilot plant at Zamsort’s Kalaba prospect. The business said the plant was completed under budget at its part-owned Kalaba prospect and has been commissioned successfully with the initial production of copper/cobalt sulphide concentrate.

Kalaba is a copper-cobalt licence covering nine of 30 high priority targets ranked by a previous JV operated by Anglo American. It is found near First Quantum’s Sentinel and Kansanshi and Barrick’s Lumwana mines. The project has an existing near-surface estimated copper-cobalt oxide resource of 16.59Mt at 0.94pc copper and a historical exploration target of 150Mt. This makes it one of the most significant projects of its type in Zambia.
