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 7th January 2022.
o Intercepts encountered in this second batch of results include (complete collar and assay tables are given at the bottom of this release):
o KKRC095: 37m @ 0.73 g/t Au from 120m to 157m (including 5m @ 2.05 g/t Au from 135m, 1m @ 1.59g/t Au from 145m, 2m @ 2.18g/t Au from 150m)

· 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.

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.

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.

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.

JORC Code, 2012 Edition | Table 1 | KKM Phase_1 drilling
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
|
|
|
Sampling techniques | · Nature and quality of sampling (e.g. cut channels, random chips, or specific specialized industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. · Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. · Aspects of the determination of mineralization that are Material to the Public Report. · In cases where 'industry standard' work has been done this would be relatively simple (e.g. 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverized to produce a 30 g charge for fire assay'). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralization types (e.g. submarine nodules) may warrant disclosure of detailed information. | · RC cuttings from a drill hole are collected in a RC cyclone after travelling through the hosepipe. Contamination in the cyclone is barred by passing compressed air after every 6m in unmineralized sections and every meter in mineralized sections. · Sample representivity is ensured by carefully passing speared chip samples on the 2:1 riffle splitter in a horizontal fashion from one end of the splitter to the other end. The splitter is cleaned using compressed air after every sampled meter. · Before any drilling program, all equipment is inspected and calibration/inspection certificates checked for compliance. |
Drilling techniques | · Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc.). | · RC drilling technique was used using a UDR650 rig. Hole diameter was the standard 5 ½". |
Drill sample recovery | · Method of recording and assessing core and chip sample recoveries and results assessed. · Measures taken to maximize sample recovery and ensure representative nature of the samples. · Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. | · Chip sample volume for every meter interval is monitored. Recovery is taken to be a factor of the average weight of the bulk sample in a drill hole. This way, a percentage is derived by dividing a particular interval's bulk sample with the average bulk sample weight and multiplying by 100. · Recovery is classified as follows: Poor (70%). · All drill holes generally had good recovery. · Sample recovery is maximized by using an auxiliary booster and compressor once the water table is encountered. · Representative nature of the samples is ensured by using both a PVC spear rod and riffle splitter during the sampling procedure. The PVC rod is speared in five different directions to extract chips in the bulk/reject sample bag. · No sample bias occurred. |
Logging | · Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. · Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. · The total length and percentage of the relevant intersections logged. | · Chip logging is both qualitative and quantitative. · Chip samples are logged geologically. Parameters recorded include lithology, alteration, deformation, structural features (e.g., veining), mineralization, colour and textural characteristics. · Total length of all drilling data is 1,231 m |
Sub-sampling techniques and sample preparation | · If core, whether cut or sawn and whether quarter, half or all core taken. · If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. · For all sample types, the nature, quality and appropriateness of the sample preparation technique. · Quality control procedures adopted for all sub-sampling stages to maximize representivity of samples. · Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. · Whether sample sizes are appropriate to the grain size of the material being sampled. | · RC Sampling: · For every meter drilled, a bulk/reject sample bag of ~40 kg is used to pack the chip samples. This bag is weighed and placed on the sampling station. It is shaken to mix contents and laid flat on the ground. A 50mm PVC spear is then used to scoop the dry chips in five different directions, diagonally and horizontally. Each scoop is carefully spread over a 2:1 riffle splitter for even distribution of chips into two plates under the splitter. Chip contents of one plate, weighing 2.5-3kg are packed in a small sample bag, which has been labelled and ticketed for dispatch to the lab. Chip contents of the other identical plate are packed in another small bag for storage in the yard (for future reference). · Contamination in the cyclone is barred by passing compressed air after every 6m in unmineralized sections and every meter in mineralized sections. · One of three CRMs are inserted in every 10 small dispatch samples for QAQC control in the lab during analysis. AMIS certificate reference materials used for QAQC control are as follows: AMIS0681 (Blank), AMIS0571 (Low-grade Au) and AMIS0724 (High-grade Au). Field-prepared duplicate samples are part of QC. Duplicate performance was good. · Sample representivity is ensured by carefully passing speared chip samples on the 2:1 riffle splitter in a horizontal fashion from one end of the splitter to the other end. The splitter is cleaned using compressed air after every sampled meter. |
Quality of assay data and laboratory tests | · The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. · For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. · Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. | · SGS Mineral Services Laboratory in Mwanza (Tanzania) analysed the RC samples. · SGS has an ISO/IEC 17025:2005 certification and SANAS accreditation. · In the lab, each sample is pulverized and weighed. A 50g aliquot is thereafter subjected to fire assay analysis with an AAS finish. · For QAQC, CRMs (in the field) were inserted for every 10 small, lab-dispatch samples. · The lab does repeat analyses on some of the samples. · Duplicate and CRM performance on the analysed samples was good. · This assay methodology is appropriate for the resource in question. · No geophysical tools were used. |
Verification of sampling and assaying | · The verification of significant intersections by either independent or alternative company personnel. · The use of twinned holes. · Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. · Discuss any adjustment to assay data. | · The internal technical team verified significant intersections. · No twinned holes were used. · Data entry is done under the guidance of RRRK's Standard Operating Procedures and verified by Project Geologists. · No adjustments were made to assay data. |
Location of data points | · Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. · Specification of the grid system used. · Quality and adequacy of topographic control. | · Drill holes were marked using a handheld Etrex 32x GPS with a 1-meter accuracy. · Coordinates were recorded in the UTM Arc1960 Zone 36S coordinate format. · Drill hole collars will be surveyed using a DGPS. · The RC holes were surveyed downhole using a Reflex camera- Single Shot technique, every 30m. · Full adequacy of topographic control will be achieved after DGPS surveying. |
Data spacing and distribution | · Data spacing for reporting of Exploration Results. · Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. · Whether sample compositing has been applied. | · Data spacing and distribution in infill drilling areas is sufficient to establish degree of geological and grade continuity appropriate for the Mineral Resource estimation procedures. · Targets undergoing anomaly testing however require further work to ensure compliance with JORC 2012 guidelines. · Sample compositing has not been applied. |
Orientation of data in relation to geological structure | · Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. · If the relationship between the drilling orientation and the orientation of key mineralized structures is considered to have introduced a sampling bias, this should be assessed and reported if material. | · Drill holes are designed to intersect subsurface structures and mineralization perpendicularly, at an azimuth angle of 25º and dip of -60º. · Azimuth and dip angles were determined from the general trend and dip orientations of host rocks. · It is not considered that drilling orientation has introduced a sampling bias. |
Sample security | · The measures taken to ensure sample security. | · Drilling samples are stored in a secured core yard within the exploration camp facility. · A chain of custody is applied while transporting lab samples to the SGS analytical facility in Mwanza. · This includes sealing all polyweave bags containing the shipment with unique tags, ticketing individual sample bags, using packing lists to organize dispatch of samples, and tracking sample movement between the point of exit and point of entry. · The lab gives a confirmation message once samples are received. |
Audits or reviews | · The results of any audits or reviews of sampling techniques and data. | · No external audit of the results, beyond the laboratory internal QAQC measures, has taken place. |
Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
|
|
|
Mineral tenement and land tenure status | · Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. · The security of the tenure held at the time of reporting along with any known impediments to obtaining a license to operate in the area. | · Mid Migori Mining Limited holds two Prospecting Licenses (PL). These are PL/2018/0202 and PL/2018/0203. The Government of Kenya through the Department of Mines and Geology granted them. The licenses have a 3-year tenure and the Company shall apply for renewal in 2023. · The licenses cover Migori, Nyatike, Kuria and Transmara areas in the southwestern part of Kenya, over a combined area of 245 km2. · RedRock has the full rights to conduct exploration activities in its license areas, which jointly constitute the Migori Gold Project. · The tenure is currently in good standing. · There are no known issues regarding security of tenure. |
Exploration done by other parties | · Acknowledgment and appraisal of exploration by other parties. | · The license area has an exploration history of more than 50 years. |
Geology | · Deposit type, geological setting and style of mineralization. | · The Migori Greenstone belt (MGB) forms part of the Nyanzian Supergroup, itself part of the northern extension of the gold-enriched Archaean Tanzanian craton. The granite-greenstone terrain to the south of the MGB is host to world class producing gold mines (e.g. North Mara: 4Moz Au and 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. |
Drill hole Information | · A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill hole collar o elevation or RL (Reduced Level - elevation above sea level in meters) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o hole length. · If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. | · A table containing collar information and interception data is included in the body of the announcement.
|
Data aggregation methods | · In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. · Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. · The assumptions used for any reporting of metal equivalent values should be clearly stated. | · All results presented are length weighted. · A cut-off grade of 0.5 g/t was used in reporting Exploration results.
|
Relationship between mineralization widths and intercept lengths | · These relationships are particularly important in the reporting of Exploration Results. · If the geometry of the mineralization with respect to the drill hole angle is known, its nature should be reported. · If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. 'down hole length, true width not known'). | · The relationship between mineralization widths and intercept lengths is not known at this time. |
Diagrams | · Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported. These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. | · Appropriate diagrams have been provided in the body of the announcement. |
Balanced reporting | · Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. | · The reporting is balanced. |
Other substantive exploration data | · Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples - size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. | · There is no other substantive exploration data associated with this release. |
Further work | · The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). · Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. | · Phase 2 drilling will follow up on significant intercepts from Phase 1 drill holes at depth, in addition to testing mineralization zones laterally along strike. Most holes will be drilled using the RC technique while a few will be DD holes but pre-collared with RC. |
