Red Rock completes RC drilling program in Luanshimba


The natural resource development company Red Rock Resources has completed a reverse circulation (RC) drilling program on the Luanshimba copper / cobalt project in Haut-Katanga province in the Democratic Republic of the Congo.

The Luanshimba project is operated by Red Rock Galaxy, an 80% Congolese subsidiary of Red Rock.

Three prospects have been drilled, at Kilembwe South, Kilembwe East and Bukulu.

There were 2,763 samples, including quality assurance or quality control samples prepared at the ALS Global preparation laboratory before being batch sent to the ALS laboratory in South Africa for analysis.

The majority of assay results have been received, but those from subsequent drill holes, some with significant visible mineralization, are still pending.

Holes have intercepted clastics from carbonaceous shales and carbonates of the Lower Roan subgroup in Zambian Copperbelt strata.

Multiple fault zones and fault grooves have been encountered at South Kilembwe where a copper / cobalt anomaly has been identified from previous soil geochemistry.

Copper / cobalt heterogenite oxide mineralization was found in multiple faults, with sulphides identified at the bottom of some holes.

At the Bukulu prospect, a pyritic zone covering chalcopyrites was found under carbonaceous shales, supporting the thesis of a vertical mineral zonation similar to the low roan copper strata of the Zambian Copperbelt.

A full interpretation and report of the scores will be made after receipt of the final test results.

The drilling program is being carried out by Rubaco, with geological support provided by Minerals Exploration Associate.

“Further results support the interpretation of a typical lower roan assemblage with prominent cobalt accompanied by copper in near-surface oxides underlying sulphide rocks with indications of vertically zoned copper minerals.

The limited penetration of the RC platform used in this initial program means that sulphide strata were not reached, in many holes, but the drilling campaign achieved its main objective by demonstrating that potentially significant mineralization, both hypogenic and supergene, took place in the license area ”, president of Red Rock André Bell said.

“It is too early to talk about discovery or economic potential, because we are awaiting the full results of the laboratory and will then have to assess both the contents, the volume of data of the strata concerned and the continuity between the holes.

“However, we can already feel encouraged by the many positive indications of this small inaugural drilling program,” he adds.
