DRC Copper & Cobalt Exploration Update
25 February 2020
Red Rock Resources Plc (LON:RRR), the natural resource
development company with interests in gold, manganese and minerals,
announces a second phase of exploration 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.
HIGHLIGHTS:
-- The license is prospective for copper and cobalt
mineralisation, and an initial programme, the results of which were
announced on 21 December 2018, identified two open-ended areas
strongly anomalous for copper and cobalt
-- Based on these results, Mineral Exploration Associates SARL
Consultants (Minex Consulting) has recommended a second phase of
exploration
-- Pitting will be undertaken in the areas C and A in Figure 1
below, on north-south lines spaced at 100m intervals with pits 40m
apart
-- Follow up trenching will be undertaken between pits where
mineralisation is encountered or further lithostratigraphical
information can be obtained
-- Geophysics will be undertaken over the north-west sector west
of 589000 E and north of 866600 S , to be followed by pitting in
area B once geophysical results have been interpreted
Red Rock Chairman Andrew Bell comments : "We obtained very
promising results from the initial exploration in a favourable
geological setting, suggesting the presence of copper and cobalt
mineralisation at depth.
As the wet season ends, we want to take the opportunity to
follow up these earlier results and find out more about the
mineralisation and the lithological units in which it is
contained.
A controlled and modular programme will enable us to test
hypotheses and step up activity quickly if justified.
We are in one of the world's most prospective environments for
the minerals we seek, working with skilled and experienced local
partners, and approach this new phase of our activity in the DRC
with considerable excitement. "

Background information :
The Luanshimba Project is a permis de recherches PR13513 held
80% by Red Rock and 20% by a local partner.
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.
A comprehensive termite mound sampling programme combined with
reconnaissance geological mapping was conducted in late 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.
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 by 500m anomaly
striking ENE, (Trend A), following 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.

Given the risk of artisanal intrusion in the event of
significant copper mineralisation being encountered in pits, Red
Rock will also seek quotes for an immediate move to a third phase
of exploration in the case of exploration success. This would be
likely to be RC drilling, and provisional planning for such
drilling assumes 4 fences at 200m intervals in area C, with 2-4
100m inclined holes, and 2 lines in each of areas A and B, for a
total of 2,500m drilled.
