Red Rock Resources Plc, the natural resource development company with interests in gold, manganese and minerals, announces the results of the soil sampling programme on license PR13513 in the Copperbelt in the south of the Democratic Republic of Congo (“DRC”) 65 km SE of Lubumbashi and near the Zambian border. The license is considered prospective for copper and cobalt mineralisation, and the commencement of the exploration was announced on 17 October 2018.
Red Rock owns 80% of the Luanshimba Project (license PR13513).
The tenement is situated along a disrupted anticline with highly prospective undifferentiated Roan sediments draping off a nearby basement dome, similar to some other productive Cu-deposits in the immediate area (Figure 1).

A comprehensive termite mound sampling programme combined with reconnaissance geological mapping was conducted over an area underlain by prospective Roan Group sediments. 452 samples were collected on a 100x100m grid, and then split, with one batch sent to ALS Laboratories in Johannesburg while the other was retained for XRF analysis.
Building on a recent regional aeromagnetic and soil sampling survey by a former ground holder, Red Rock has now identified as a result of the programme 2 strongly anomalous areas that are open-ended:
· In the southern part of the licence, a 2km long anomaly up to 500m wide striking ENE, (Trend A), 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.
· Anomalous metal assays with peak values of 519ppm Cu and 425ppm Co corroborate and exceed the XRF values and are partly coincident with above average contents of pathfinder elements Bi and V. Given the regionally low background, these results are considered indicative of likely Cu-Co mineralisation at depth.
· Occasional outcrops reveal limonitic coatings and tiny cavities after sulphides along with occasional malachite that also explain the occurrence of copper-tolerant flora.
· The northern anomaly, (Trend B), a SE- striking copper-cobalt anomaly some 1,400m by 300m wide, while more subdued, is still significant as it clearly mimics the regional metalliferous stratigraphic and structural trend.

These encouraging results confirm the favourable geological configuration and Red Rock consultants Minex Consulting SARL have recommended a ground geophysical survey and pitting or trenching over selected areas, possibly to be followed up by RC drilling.
Red Rock Chairman Andrew Bell comments: “The promising results obtained from initial exploration in this favourable geological setting suggest the presence of copper and cobalt mineralisation at depth, and further work will be carried out. Should pitting results confirm the prospectivity, we would expect to move on to a RC drill programme.”
