Kenya Exploration Update
Mikei Gold Project - Drill Programme Second Batch Assay Results
22 March 2022
Red Rock Resources Plc ("Red Rock" or "the Company"), is a natural resource
development company with interests in gold, manganese and base metals,
principally in Africa and Australia. Further to the announcement made on 7th
January 2022, the company today announces results of second batch of 1,365
samples (including QAQC) from its phase 1 RC drilling exploration programme in
the mid KKM prospect of the Mikei Gold Project ("MGP") in Kenya.
MGP is 100% beneficially owned by Red Rock. The drill programme was carried
out by Base Drilling (Tanzania), with geological supervision by Red Rock's
in-house geological team.
HIGHLIGHTS:
o A total of 20 drill holes totalling 2093 meters were completed in the
phase 1 RC Drilling Programme at the KKM Prospect and sampling and logging was
done at 1 metre intervals by our in-house geological team prior to being sent
to SGS Limited in Mwanza, Tanzania for accredited laboratory assay.
o Results are of second batch of 1,365 samples from the last 11 out of the
20 holes drilled in the programme. Results of the first batch of 9 drill holes
(950 samples) were announced on the 7(th) January 2022.

· KKM is the Mid Prospect of the five main MGP Prospects and has an
Indicated and Inferred (JORC 2012) Resource of 371.3 Koz Au. Gold
mineralization at KKM is both structurally and chemically controlled through a
regional NW-SE trending shear zone and its rich quartz porphyry intrusions and
graphitic shale envelopes respectively.
In other areas:
· 7.5 line km of PDP IP completed at KKM and KW prospects.
· 33 line km of Gradient IP and 3 line Km of Pole-Dipole IP have
been completed in the Homestead prospect of the Eastern Licence.
· 55.6 line km of Gradient IP and 2.6 line km of Pole-Dipole IP
have been completed at the Juakali-Kehancha Prospect of the Eastern Licence.
· EIA on four of the remaining prospects (NZ, KW, MK and GM) at the
MGP was completed and EIA licence issued.
· 9 trenches (total 450m) planned mapping and sampling programme as
a follow-up to the recently completed IP campaign at Masurura Prospect of the
Eastern Licence.

Red Rock Chairman Andrew Bell comments: "15 of the 20 holes drilled in the
first drill programme since restoration of the licences encountered
mineralisation at or above above our cut-off, with some very wide intercepts.
This is very solid progress and a good result.
The objects of this first programme were to guide us as to where we might
increase the Resource size, improve the reported grade, or upgrade the
categorisation. Of these 11 holes, some of which were testing for extensions
of known mineralisation, 9 intersected gold above our cut-off grade, and we
assess that 4 provide additional grade information, 4 might have bearing on
the size of the mineralised envelope, and 1 might provide information relevant
for both grade and category estimates.
The information derived from this initial small programme, carried out by our
new geological team, does not provide information sufficient yet to justify a
recalculation of the Mineral Resource Estimate but it points us to the most
productive work for the next stage, where our objective will be to lead up to
a new MRE. The greatest impact is likely to come either from diamond drilling
deeper but still within the pit shell and down dip, where we hypothesise the
existence of higher grades, or from the bringing to Resource of new areas
where mineralisation has been encountered but few holes have been drilled.
Some potential exists from infill drilling nearer surface at mid-KKM and its
satellite deposits, but this is likely to be a lower priority.
Detailed planning of the next drill programme, which will be predominantly
diamond drilling, is now under way, and will be assisted by external
consultants."
Summary of Drill Results
Results from the latest batch bore significantly wide intercepts with some
holes having multiple intercepts above the 0.5g/t cut-off grade as seen in
KKRC095 and KKRC097. Out of the 11 drill holes, 9 returned extensive
mineralized zones.

(http://www.rns-pdf.londonstockexchange.com/rns/5219F_2-2022-3-21.pdf)
The results confirm the crucial role quartz porphyry plays as a mineralization
control in the prospect. Notwithstanding that porphyry stock in the prospect
is defined by both feldspar and quartz, it is in the quartz porphyry that most
of the important intersections are hosted, notably around contact boundaries
with black graphitic shale envelopes as noted at KKRC091 and KKRC089.

(http://www.rns-pdf.londonstockexchange.com/rns/5219F_3-2022-3-21.pdf)
The main sulphides closely associated with auriferous zones are pyrite and
arsenopyrite. Stibnite occurs at one of the more important zones in KKRC087,
offering a new and fresh dimension into future gold-association studies in the
prospect. Major alterations constituting the mineralogical suite are
sericitization, carbonatization and chloritization. Interpretational zoning of
these alteration signatures will lead to mapping of the core of the porphyry
systems, which could have a mineralogical implication.

(http://www.rns-pdf.londonstockexchange.com/rns/5219F_4-2022-3-21.pdf)
In addition, the results lay bare the positive implications to the mineral
resource through more lateral and down-dip drilling as reflected on the
intercepts of drill holes KKRC087, KKRC097 and KKRC091.

Background
The MGP (100% beneficially owned by Red Rock) comprises two prospecting
licences which cover approximately 245 km2, namely PL/2018/0202 and
PL/2018/0203, over the Migori Greenstone Belt, and are located along the
northern margin of the Tanzanian Craton. The licences extend 63 km along the
strike of the belt, which also hosts the Kilimapesa Gold treatment plant
several km to the east of the Company's licenses. The North Mara Gold Mine,
which is operated by Barrick Gold, is located 30 km to the south of the MGP in
Tanzania.
Regional exploration in the project area began in the early 1930s and
culminated in the identification and subsequent mining of the Macalder
volcanogenic massive sulphide (VMS) base metal mine.
In 2010, Red Rock began the extensive task of file organisation, data
digitisation and compilation of available historical data, following which CSA
Global (UK) Ltd performed cross-checks and validation steps prior to loading
it into a Structured Query Language (SQL) database using Datashed. During 2011
and 2012, Red Rock undertook an infill drilling programme at all five of the
lode gold prospects; MK, Kakula-Kalange-Munyu (KKM), Kakula-Kalange-Munyu West
(KW), Nyanza (NZ), and Gori Maria (GM) within PL/2018/0202.The Report
published earlier this year documented the results of Mineral Resource
estimation work initially conducted in 2011 and 2012 and revised in 2021 in
order to report the Mineral Resources according to JORC (2012)
guidelines.
JORC (2012) differs from earlier editions of the JORC Code in that for a
Mineral Resource to be estimated it requires the application of "reasonable
prospects of eventual economic extraction" ("RPEEE") principles. This has
resulted in the case of the Mikei MRE in the calculation of pit shells
supported by conceptual cost and gold price forecast parameters. Any material
outside or below the reporting pit shell was updated as "Not Classified" since
it did not meet the criteria to be reported as a Mineral
Resource.
The total Mineral Resource Estimate, at both Inferred and Indicated levels,
was estimated at:
15.13 Mt @ 1.49 g/t Au with contained metal content of 723 KOz Au
All prospects, except GM, were classified as Indicated and Inferred Mineral
Resources. GM was classified as Inferred only, mainly due to the relatively
low average RC drill recovery of 62%.
Due to the uncertain lateral extent and depth of artisanal mining at the Mikei
prospects, and the lack of topographic data to accurately deplete the Mineral
Resource, all oxidised material was classified as Inferred Mineral Resources.
The Mineral Resource was reported as that material within the RPEEE pit
shells, and above a cut-off grade of 0.5 g/t Au. The Mineral Resource was
reported as of 18 January 2021.
The technical information in this release has been reviewed by Mr Joseph Komu,
a member of AusIMM and the Project Manager of the Project. He is a member of a
recognised professional organisation and has sufficient relevant experience to
qualify as a qualified person as defined in the Guidance Note for Mining, Oil
and Gas Companies published by AIM.

Geita: 7Moz Au). The Tanzanian craton is of a similar age to other significant
orogenic gold belts such as the Yilgarn in Australia and the Lake Superior
province in Canada. The mineralization and stratigraphy of the MGB is
similar to that of the Lake Victoria Greenstone belts in Tanzania and other
Archaean greenstone deposits such as Red Lake in Canada (3.2Moz Au). Gold
enrichment within the MGB is predominantly found in and around shear zones
associated with quartz-carbonate veining and significant alteration, as well
as banded iron formations (BIFs) and polymetallic Volcanogenic Massive
Sulphides (VMS). The dominant lithologies are felsic and mafic intrusive, BIFs
and metasediments of the Nyanzian system, overlain by younger Kavirondian
volcaniclastic sediments and intruded by younger granitic intrusions.
