ASX Announcement
24 February 2022
Scale and continuity confirmed at Bandjougoy with significant thickening of iron mineralisation
Assays for remaining diamond drill holes expected over coming weeks triggering a maiden Oxide Mineral Resource estimate due Q2 2022
Highlights
-
Diamond drilling Oxide Mineral Resource growth program comprising 26 holes for approximately 2,930m completed in late 2021 at the Bandjougoy prospect.
-
First six (6) diamond drill holes representing two (2) sections reported in November 2021 confirming scale and suitability for shallow, open pit mining.
-
Diamond drill results reported in this announcement represent the next eight (8) holes over three (3) sections for an interpreted strike extent of 800m. With this announcement, 14 of 26 diamond drill holes now reported, results of the remaining 12 holes expected in the coming weeks.
-
These new drill results show a significant thickening of iron mineralisation to the west, continuity over the drilltested 3km of the modelled 4.4km strike extent, and continues to validate Bandjougoy’s suitable geometry for the potential development of a large-scale open pit mining operation.
-
Bandjougoy, with a strike length of 4.4km, is the single largest target for Oxide mineralisation at Baniaka without an Oxide Mineral Resource; it has an in-situ Oxide Exploration Target of 67-124 million tonnes at 35-49% Fe[1] .
-
Earlier pilot scale metallurgical test work results reported in September 2021 on bulk Bandjougoy Detrital Iron and Soft Oxide samples returned Lump, Fines and Pellet Feed products between 62 and 65% Fe.
-
The drill results substantiate Genmin’ s strategy to centre mine infrastructure adjacent Bandjougoy the Baniaka Preliminary Feasibility Study, scheduled for completion Q2 2022.
African iron ore explorer and developer, Genmin Limited ( Genmin or Company ) (ASX: GEN), is pleased to report the results of a further eight (8) diamond drill holes representing three (3) drill sections from the recently completed diamond drilling program at its 100% owned Baniaka Iron Ore Project ( Baniaka ), located in the Republic of Gabon, Central West Africa (Figure 1).
1 Information regarding the Bandjougoy Exploration Target is extracted from the “Independent Geologists Report on the Mineral Assets of Genmin Limited” dated January 2021 ( IGR ) authored by SRK Consulting (Australasia) Pty Ltd. The IGR is included in the Company’s Prospectus dated 9 February 2021. The Bandjougoy Exploration Target is conceptual in nature, there has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.

Managing Director and Chief Executive Officer, Joe Ariti commented: “We are extremely pleased with these diamond drilling results from Bandjougoy. These results show excellent geological continuity with a significant thickening of iron mineralisation to the west, providing an ideal starter location for open-pit mining activities. In this area, Oxide thicknesses are up to 65m beneath the existing detrital iron mineral resource, validating our strategy to centre mine infrastructure for Baniaka adjacent to Bandjougoy in the PFS, as it is likely to form the mainstay of initial mining activities”.
He added: “Remaining assays for the balance of the diamond program are expected in the coming weeks, triggering the commencement of a maiden Oxide mineral resource estimate. The Bandjougoy maiden Oxide mineral resource will not only increase Baniaka’s Oxide resource inventory but will provide additional Soft Oxide material for production of a pellet feed product. Pellets are a greener feedstock for blast furnace iron making, as they do not require sintering, and as China’s steel making industry decarbonises, we expect to see greater demand for pellets”.
Bandjougoy Drilling Results
The diamond drilling program comprising 26 holes for 2,930m was completed at the Bandjougoy prospect (Figure 2) in late 2021. Drilling reported to date has intersected oxidised iron mineralisation ( Oxide ) beneath the Detrital Iron Deposit ( DID ) mineralisation over 3km of the total strike length of 4km being tested at Bandjougoy during the diamond drilling program. Oxide iron mineralisation comprises both Soft Oxide and Intact Oxide material types. DID and Soft Oxide are the initial targets to support a mining operation at Baniaka.
The 2021 diamond drilling program at Bandjougoy builds on an initial 12 exploratory diamond drill holes for 1,186m completed in 2018. The 2018 drilling confirmed Oxide and Primary mineralisation on the eastern part of Bandjougoy (significant intercepts were reported in the IGR included in the Company’s Prospectus dated 9 February 2021). The 2021 diamond drilling program was designed to confirm Oxide mineralisation over a continuous 4km of the possible 4.4km strike length of Bandjougoy (Figure 3). This drilling program was completed in Q4 2021, and comprised 26 holes for approximately 2,930m. Results for the first six (6) of these 26 holes were reported to the market on 23 November 2021 and comprised the easternmost two drill sections BJ323 000E and BJ322 000E.
Results reported in this announcement comprise a further eight (8) drill holes for a total of 1,027.5m over three (3) sections (BJ321 800E, BJ321 400E, and BJ321 000E) extending through the centre and west of Bandjougoy. All analytical results were reported by ALS laboratories at Loughrea, Ireland, and Johannesburg, South Africa.
All eight (8) holes were successful in intercepting in-situ Oxide and/or Primary Banded Iron Formation ( BIF ) mineralisation at downhole depths that were forecast during drill planning. DID mineralisation was also intercepted in drill holes that were collared in areas with surface projection of the BIF.
Significant intercepts and collar locations are provided in Table 1 and Table 2, with key Oxide (comprising both Soft Oxide and Intact Oxide material) intervals listed below:
-
49.5m at 45.0% Fe from 10.5m in BWDD019;
-
48.5m at 38.2% Fe from 16.5m in BWDD020;
-
61.1m at 47.9% Fe from 6.4m in BWDD021;
-
18.2m at 53.8% Fe from 8.3m, and 52.2m at 43.3% Fe from 30.5m in BWDD024; and
-
57.5m at 45.0% Fe from 7.8m in BWDD025.
Significant DID intervals are further listed below:
-
6.5m at 52.7% Fe from 4.0m in BWDD019;
-
12.3m at 44.8% Fe from 4.3m in BWDD020;

Drilling on the two newly reported sections BJ321 400E and BJ321 000E (Figure 3) targeted lateral continuity and downdip extension of iron mineralisation from the westernmost section reported in the IGR (BJ321 800E, Figure 4). It further tested the strike extension of in-situ BIF and its oxidised and enriched by-products (Figure 5 and Figure 6).
All three sections confirm the presence of in-situ BIF along strike and at depth, with true thicknesses ranging from approximately 125m on section BJ321 000E to 155m on section BJ321 800E.
This represents a noteworthy thickening of the BIF in comparison to true thicknesses in the range of 55-60m encountered in the easterly BJ322 200E and BJ323 000E sections and confirms the Company’s hypothesis stated in the ASX announcement dated 23 November 2021 that the elevated ground magnetic anomaly noted between 320000mE and 322000mE (Figure 3) represents thickening of the BIF. The reasons for this thickening are considered to be folding or fault repetition of the BIF and will be investigated in due course.
The target Oxide zone of the BIF is well developed in all three (3) sections. The development of the Oxide zone is strongly affected by both primary geological and weathering controls, the combined effects of which have resulted in the zone dipping very gently at approximately 10-20 degrees to the North in the same direction of dip of the Primary BIF. This is consistent between all three (3) sections with Oxide thicknesses typically in the order of 50-65m measured perpendicular to the weathering surfaces.
The Soft Oxide component of the Oxide zone is consistent and well developed with thicknesses up to 45m and averaging approximately 30m. Lateral continuity and thicknesses of the Soft Oxide and overlying DID zones are of significance in supporting the Baniaka Preliminary Feasibility Study ( PFS ), which focuses on these enriched zones of mineralisation that are close to ground surface and amenable to open pit mining methods.
The BIF in section BJ321 000E contains a wedge of unmineralized metasediments that extends between diamond drill holes BWDD022 and BWDD023. The presence of this unmineralized unit is supported by a locally suppressed response of ground magnetic data (Figure 3). This unmineralized unit is considered to be laterally discontinuous beyond section BJ321 000E, not being encountered on adjacent section BJ321 800E. This interpretation is supported by more consistent magnetic responses on the adjacent sections. The geometry of this wedge of waste metasediment will be further constrained by subsequent drilling.
The three (3) diamond drill sections reported in this announcement materially contribute to extending the mineralised envelope westward at Bandjougoy, yielding positive DID, Oxide and Primary drill results. The extent of mineralisation at Bandjougoy is now 3km of the 4.4km of prospective strike (identified from modelling and interpretation of ground magnetic data and verified with shallow auger drilling). Significant thickening of the BIF and its associated enriched weathering by-products was encountered as expected between BJ321 000E and BJ321 800E.
The Primary BIF mineralisation remains open at depth[2] on all five sections reported to date and represents a strategic target to define a significant underlying magnetite asset at Bandjougoy.
Infill Reverse Circulation ( RC ) drilling is ongoing at Bandjougoy to achieve drilling densities considered appropriate to support a Mineral Resource Estimate that achieves a minimum Indicated classification.

Bandjougoy: Updated Context & Significance
The significance of the Bandjougoy prospect was previously stated in the market announcement dated 23 November 2021. The following complementary criteria that were set out previously in support of Bandjougoy’s significance are restated, along with supporting commentary in italics from the drilling included in this announcement:
- The BIF at Bandjougoy typically dips at approximately 30 to 40 degrees to the North. The shallow dip results in wider horizontal thickness exposed to weathering and iron enrichment. There is, therefore, greater potential volume of DID and Oxide mineralisation per vertical metre that may be amenable to shallow, open cut mining when compared to more steeply dipping BIF units.
This hypothesis is now supported by five (5) drill sections, that further demonstrate that the lower boundary of the Oxide mineralisation dips at 10-20 degrees also to the North.
2. An elevated ground magnetic anomaly is noted between 320000mE and 322000mE (Figure 3), which is considered to represent thickening of the BIF unit.
-
Sections BJ321 000E, BJ321 400E, and BJ321 800E confirm thickening of the BIF up to 150m, which translates to more significant development of enriched Oxide mineralisation. The elevated ground magnetic anomaly extends a further 600m to the west and positive Oxide intercepts are expected on section BJ320 600E with results to be released in the coming weeks.
-
The presence of the overlying DID Mineral Resource reported to the market on 21 July 2021; and
-
Bandjougoy represents the strike extension of Tsengué contiguous to the East. Tsengué has DID, Oxide and Primary Mineral Resource estimates that have previously been reported to the market.
The drill results in this announcement reinforce the scale and significance of the Bandjougoy prospect. Consequently, Genmin’s strategy is to centre mine infrastructure adjacent and proximal to Bandjougoy in the PFS, and for it to form the mainstay for the initial years of proposed mining activities at Baniaka.

Section 1 Sampling Techniques and Data
Sampling Techniques
Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as downhole 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.
Diamond drill core is the sampling method reported in this announcement. The core is sampled as quarter (PQ diameter) or half core (HQ or NQ diameter) to a nominal 2m in the residuum and BIF and broken by changes in dominant lithology. A nominal 4m length is used in non-BIF lithology.
•
- Sampling of the DID and in-situ BIF lithologies is systematically conducted over the full drilled interval of those lithologies for all drillholes. No selective methods are used in the collection of samples from diamond drill holes. The diamond drill sampling is consistent with peer iron ore projects and is considered representative of the lithologies under investigation.
•
• A Terraplus KT10 Plus handheld magnetic susceptibility meter is used to collect measurements every 50cm on diamond core. The instrument manual states that the KT-10 meter is calibrated at the factory and a periodic calibration is not required.
Aspects of the determination of mineralisation 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 1m samples from which 3kg was pulverised to produce a 30g 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 mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information.
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.).
• Diamond drilling for the 2021 program reported in this announcement was completed using a track mounted Longyear LF™90 chuck drive coring rig operated by contractor Boart Longyear.
- Drill holes pass through the residuum blanket, with hole azimuth and dip designed to target orthogonal penetration of the underlying BIF units. Through the residuum, hole size is typically PQ3 diameter (83.1mm), HQ3 (61.1mm) diameter in soft material and NQ (47.6mm) in competent rock. Core in unconsolidated and soft material is routinely recovered using a triple tube core barrel to optimise core recovery.

|---|---|
| • Core is oriented in consolidated ground, below the residuum and Soft Oxide, using a Boart Longyear TruCore™ core orientation tool. • Drill holes are surveyed using a Stockholm Precision Tools (SPT) Gyromaster™ north seeking gyroscopic downhole survey tool for dip and azimuth. |
|
| Drill Sample Recovery | |
| Method of recording and assessing core and chip sample recoveries and results assessed. Measures taken to maximise 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. |
• Diamond core recovery is measured by a technician at the drill rig and marked up on the core tray. Core recovery is recorded in the geological database and reviewed systematically. Lower recoveries are predominantly encountered in unconsolidated ground. Measures taken to ensure high recoveries are maintained in poor ground conditions include retrieval of core in 0.5m runs, and the extensive use of triple tube core barrels in oxidised lithologies. |
| 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. |
• Diamond core is cleaned to reveal undisturbed material, assembled, oriented, measured, marked-up and photographed prior to being systematically logged for geology (regolith, lithology, texture and dominant minerals) and geotechnical parameters. • Where core is oriented, representative structures are recorded on a regular basis, with corresponding confidence in the measurements. • Core is subsequently cut for sampling. • All logging is cross-checked with magnetic susceptibility measurements and assay data subsequent to receipt to ensure any anomalous or erroneous grade-lithology relationships are identified and recognised or logging corrected, as necessary. • All remaining core is kept indefinitely on site after sampling in the Baniaka sample storage facility, including the remaining unconsolidated materials that is too friable to cut. • All sample intervals are logged for the entire length of the drill hole regardless of lithology. |
| 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. |
• Diamond drill core is cut in quarter (PQ diameter) or half (HQ and NQ diameter) using a core saw and sampled to meet the desired sample mass. • Samples are put into numbered plastic bags with pre-numbered sample tickets and stored in lots in labelled large plastic bags. • In unconsolidated ground, material is split using a core splitter or large pallet knife depending on sample hardness. |

Comment
For all sample types, the nature, quality and • appropriateness of the sample preparation technique. Quality control procedures adopted for all sub-sampling stages to maximise 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/secondhalf sampling.
Core samples are prepared at Intertek Genalysis Owendo near Libreville using the following protocol: drying at 105°C, crushing to 80% passing (P80) 2mm, riffle splitting and pulverisation to P80 passing 75μm; and packaging and shipping to an external independent analytical laboratory, ALS Limited (ALS).
Field duplicates are collected as part of the sample preparation process at a rate of one in twenty samples and examination of the results indicates no material bias is present. The sample size is adequate given the particle sizes involved. A 5 kg sample weight is targeted in the residuum where particles are the largest (top size circa 35 mm) consistent with the nomogram method given in the Field Geologists’ Manual Fifth Edition, Monograph 9, published by The Australasian Institute of Mining and Metallurgy, Carlton, Victoria 3053 Australia.
Whether sample sizes are appropriate to the grain size of the material being sampled.
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.
- Samples are analysed at ALS Laboratory facilities at both Loughrea, Ireland, and Johannesburg, South Africa. Analysis is conducted for a suite of 24 elements and oxides by ME-XRF21u (lithium borate fusion and XRF finish on fused disks) and loss on ignition at 371, 650 and 1 000°C by OA-GRA05x (Muffle Furnace). The techniques are industry standard for iron ore assaying and are consistent with similar analytical packages offered by Intertek, SGS, and Bureau Veritas laboratories.
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. •
- Magnetic susceptibility is measured using as handheld KT-10 Plus Terraplus meter and the resulting data is used to aid geological interpretation.
Certified Reference Material (CRM) samples are inserted at a rate of one per 50 samples. CRM samples are sourced from Geostats Pty Ltd and include four iron grades ranging 25.6-63.0% Fe. Certified blank material (OREAS 22e) is inserted at a rate of one per 50 samples.
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.
• Field duplicates are inserted at a rate of one per 20 samples.
Verification of Sampling and Assaying
The verification of significant intersections by either independent or alternative company personnel.
• Significant intersections are compiled and validated prior to being reported publicly through internal review by Competent Persons who have consented to the release of this announcement.
The use of twinned holes.
- No holes reported in this announcement have been twinned.
Documentation of primary data, data entry procedures, • data verification, data storage (physical and electronic) protocols.
- No laboratory analytical samples have been validated using alternate laboratory facilities. This practice is however routinely implemented prior to the inclusion of exploration data into Mineral Resource estimations, and will be completed during the latter stages of the drill program.

| Location of Data Points | |
| Accuracy and quality of surveys used to locate drill holes (collar and downhole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. |
• The topography is a Digital Elevation Model (DEM) surface created from a high-resolution LiDAR point mesh calibrated and validated with Differential Global Positioning System (DGPS) points collected throughout the airborne survey area. The LiDAR survey data was classified according to the international LAS standard and format, and the bare earth class used for topographic model generation that excludes vegetation. • The grid system is WGS84, UTM Zone 33S. Where possible, DGPS points have been added to the LiDAR survey DEM to improve local accuracy. • Drill collars are pegged using handheld GPS units with a nominal accuracy of 15m. The Company has conducted a Differential GPS (DGPS) and total station survey to achieve centimetre level accuracy for all drill collars following completion of the 2021 drilling program. Revised coordinates for drill collars are outstanding at the time of this announcement. • All drillholes that are used in BIF Mineral Resource Estimates are surveyed with the DGPS method. • All diamond drill holes reported in this announcement were surveyed using a Stockholm Precision Tool (GyroMaster™) to confirm inclination and azimuth. |
| 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. |
• The intent of the 2021 drill program is to provide geological and analytical information of sufficient confidence to be included in a Mineral Resource estimation to achieve the Indicated category of classification. The dominant section spacings for diamond and RC drill holes in the 2021 and 2022 drill programs are set to achieve 200m section spacing, and 50m drill spacing along sections when combined with RC drilling. This spacing has achieved Indicated Mineral Resource classification in DID mineralisation both at the eastern portion of the Bandjougoy prospect, and at Tsengué. No Mineral Resources have yet been estimated at Bandjougoy in the in-situ oxidised BIF lithologies that underlie the DID mineralisation. Although Mineral Resources have been estimated for DID mineralisation at Bandjougoy, and along strike to the East in both DID and in-situ BIF lithologies at Tsengué, there has been insufficient exploration to determine a Mineral Resource in the oxidised BIF at Bandjougoy. • DID, oxidised, and Primary BIF samples are composited to 2m intervals, respecting geological boundaries as necessary. |

Orientation of Data in Relation to Geological Structure
Whether the orientation of sampling achieves unbiased • Diamond drilling targets the in-situ BIF, which generally dips from 30 to 40 degrees north or northwest at Bandjougoy.

Laterite mineralisation. duricrust (LAT) and gravels (LCOL) are developed on the metamorphic rocks that flank the BIF units. Canga duricrust (CAN) and DID gravels are developed on BIF bedrock, forming the mineralised body. The LAT, LCOL, CAN, DID and HYB units are collectively termed the residuum. The residuum varies from 1 m to 16 m thick.
-
• In situ BIF underlies the residuum and is divided into three main categories based on changes in the degree of weathering, iron oxide mineralogy, magnetic susceptibility and material strength with increasing depth below the residuum. The three categories ordered by reducing oxidation state are as follows:

• The residuum within the project is horizontal to sub-horizontal and is closely related to topographic variations. • In-situ BIF lithologies dip at approximately 30 to 40 degrees to the North. Drill hole direction and inclination has been planned to intersect BIF lithologies orthogonally where possible, as is noted on cross sections included in this announcement. • The significant DID, Oxide and Primary intercepts reported in this announcement are down-hole lengths. True thickness of the BIF was estimated on interpreted sections. • Sample intervals are considered appropriate for the style of mineralisation in the project area and are consistent with other publicly reported iron ore assets. |
