Red Rock Resources PLC (AIM:RRR) has completed its maiden drilling programme at the Luanshimba copper-cobalt project in the Democratic Republic of Congo.
It has received the majority of assay results, but said it was still awaiting those from later holes including some with significant visible mineralisation.
“Further results support the interpretation of a typical Lower Roan assemblage with prominent cobalt accompanied by copper in oxides near surface underlain by sulphide-bearing rocks with indications of vertically zoned copper minerals,” said chairman Andrew Bell.
“The limited penetration of the RC [reverse circulation] rig used in this initial programme means that the sulphide-bearing strata were in many holes not reached, but the drill campaign has achieved its primary objective in evidencing that potentially significant mineralisation, both hypogene and supergene, has taken place within the licence area.
“It is too soon to speak of a discovery or of economic potential, as we await the full results from the laboratory and will then have to assess both the grades, the volume of data from the relevant strata, and the continuity between holes.
“However, we can already feel encouraged by the many positive indications from this small maiden drill programme. We look forward to giving a full report within the next weeks,” he concluded.
Red Rock said 2,469 metres of drilling was undertaken at three prospects – Kilembwe South, Kilembwe East, and Bukulu – in 29 holes at depths between 60 and 100 metres.
Red Rock owns and operates 80% of Luanshimba, which is situated in the Haut-Katanga province in the Congolese Copperbelt.
