Red Rock Resources PLC (LON:RRR) said initial exploration at the Luanshimba project in the Democratic Republic of Congo has shown promising results that suggest the presence of copper and cobalt mineralisation at depth.
Soil sampling at license PR13513 has identified two strong anomalous areas that are open-ended.

This included anomalous metal assays with peak values of 519parts per million (ppm) copper and 425ppm cobalt corroborate, exceeding values that were indicated using the XFR analyser. These results are considered indicative of likely copper-cobalt mineralisation at depth.
In the southern part of the licence, there was a 2km long anomaly up to 500m wide follows carbonaceous shale and silicified dolomite into the nose of a disrupted anticline underlain by known upper roan silicified dolomite and carbonaceous shale adjacent oxidised sandstone.
The group said the results confirmed favourable geological configuration and its consultants Minex Consulting SARL have recommended a ground geophysical survey and pitting or trenching over selected areas. That will be possibly followed up with reverse circulation drilling.
