Red Rock Resources Plc, the natural resource development company with interests in gold, manganese and copper, announces progress to date on the ground geophysics programme announced on 20 November 2020 at the Company’s 80% owned Luanshimba License in the Democratic Republic of Congo.
The programme has been carried out under the supervision of Minerals Exploration Associates SARL (“Minex Consulting SARL”) and the first two phases have been completed:
· 70.72 line-kilometres of magnetic data was collected in December 2020 by a ground survey conducted on north-south lines with a 100m line spacing
· Ronacher McKenzie Geoscience of Sudbury, Ontario processed and interpreted the ground magnetic data during January 2021
· Three magnetically anomalous areas were observed: in the northwest, in the east, and a third magnetic high in the southwest
· An anomalous magnetic response in the southwest coincides with zones of elevated soil geochemical Cu and Co and may coincide with a mapped fold nose with postulated congruent structures that resemble other significant Cu-Co occurrences in the district
· The southwest anomaly is considered the highest priority for a follow up ground geophysics programme of IP (Induced polarisation) which will begin shortly
· Plans for a 12 line-kilometre IP and resistivity programme comprising six 2 km lines across the three target areas may be extended to eight lines to ensure thorough testing of the targets
· IP/resistivity data will then be integrated with the magnetic and geochemical data to delineate immediate drill targets
Red Rock Chairman Andrew Bell comments : “The pattern of good confirmatory results from this tenement continues, and our advisors are optimistic about the prospectivity.
The geological setting of the southwest anomaly conforms to the structural pattern in which significant deposits have historically been found and the strongly anomalous geochemical results show the presence of copper and cobalt in the area.
We must now move quickly towards the drill stage as the rainy season draws to a close.”

Red Rock owns 80% of the Luanshimba Project, which is situated 65 km south-east of the provincial capital of Lubumbashi in Haut-Katanga, in a 420 hectare prospecting license (PR13513) in the Congolese Copperbelt.
The tenement is situated along a disrupted anticline with undifferentiated Roan sediments of the Mwashya Subgroup draping off a nearby basement dome, similar to some other Cu-deposits in the immediate area.
A comprehensive termite mound sampling programme combined with reconnaissance geological mapping was conducted in 2018 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.
Red Rock identified in the southern part of the licence, a 2km long anomaly up to 500m wide striking ENE, with anomalous metal assays with peak values of 519ppm Cu and 425ppm Co, corroborating earlier XRF values and 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.
In the north, 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.
