Diamond drilling Oxide Mineral Resource growth program completed at Bandjougoy prospect.
Program comprised 25 holes for approximately 3,000m and builds on 12 diamond holes completed in 2018.
Drill results reported in this announcement represent the first 6 of the 25 diamond holes. Assay results pending for the remaining 19 holes. Drill results continue to confirm a large-scale,flat-lying mineralised system at or near surface.
Bandjougoy's strike length of 6.3km is the single largest target for Oxide mineralisation at Baniaka without an Oxide Mineral Resource; it has an in-situ Oxide Exploration Target of 67-124Mt at 35-49% Fe1.
The strike length and width of Bandjougoy show favourable geometry for the potential development of a large- scale open pit mining operation.
Pilot scale metallurgical test work on bulk Bandjougoy Detrital Iron and Soft Oxide samples returned Lump, Fines and Pellet Feed products between 62 and 65% Fe.
Bandjougoy is now anticipated to provide the centre of gravity for the Baniaka Preliminary Feasibility Study, which is scheduled for completion at the end of Q1 2022.
African iron ore explorer and developer, Genmin Limited (Genmin or Company) (ASX: GEN), is pleased to report the results of the first two (2) drill sections from its recently completed diamond drilling program at the Bandjougoy Forprospect at its 100% owned Baniaka Iron Ore Project (Baniaka) located in the Republic of Gabon, Central West
Africa (Figure 1).
Drilling intersected oxidised iron mineralisation (Oxide) beneath the Detrital Iron Deposit (DID) mineralisation at Bandjougoy (Figure 2 and Figure 3). Oxide iron mineralisation comprises both Soft Oxide and Intact Oxide material types. DID and Soft Oxide are the primary targets to support a mining operation at Baniaka.
Managing Director and Chief Executive Officer, Joe Ariti commented: "The drill results continue to confirm the large- scale Oxide potential of Bandjougoy that is approximately 300 metres wide, gently dipping and immediately beneath the flat-lying surficial DID. The shallow dip would enable simple open pit extraction with a high mining yield per vertical metre in comparison to more steeply dipping systems, with low stripping ratios on commencement of mining due to DID at or close to ground surface with a thin veneer of unconsolidated cover. Pilot scale metallurgical test work on
1 The 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.

both DID and Soft Oxide bulk samples from Bandjougoy returned 62-65% Fe grades across a suite of Lump, Fines and Pellet Feed products."
only"We are targeting the definition of an Oxide Mineral Resource at Bandjougoy to complement its DID Mineral Resource and given its potential scale and proximity to existing Mineral Resources at Tsengué, Bandjougoy is likely to form the centre of gravity for infrastructure layout in the Baniaka Preliminary Feasibility Study", he continued.
In-situ iron grades from Oxide mineralisation reported in the first two completed sections are in line with the feed grades for bulk Soft Oxide metallurgical samples from Bandjougoy. Sample MIN06039 graded 48% Fe as reported n 15 September 2021 and sample MIN6030 graded 35.3% Fe as reported on 29 October 2021. Both samples
achieved +62% Fe product grades during pilot scale test work.
Bandjougoy Drilling Results
useThe 2021 diamond drilling at Bandjougoy builds on 12 diamond drill holes completed on the prospect in 2018. These new holes were drilled on 400m and 800m spaced sections and confirmed Oxide and Primary mineralisation on the eastern part of Bandjougoy (significant intercepts were reported in the Company's Prospectus dated 9 February 2021 (Prospectus)).
The 2021 diamond drilling program at Bandjougoy comprises approximately 3,000m for 25 holes. The drill results reported in this announcement represent the first six (6) of these 25 holes with assays received from ALS laboratories at Loughrea, Ireland, and Johannesburg, South Africa.
personalThe holes targeted the downdip extension of iron mineralisation on existing section BJ323000E (drill hole BWDD013, Figure 4) and tested the possibility of deeper oxidation and iron enrichment along an interpreted structure on newly reported section BJ322200E (Figure 5).
All six (6) holes for a total of 522.5m drilling were successful in intercepting Oxide and/or Primary mineralisation at downhole depths that were forecast during drill planning.
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:
Genmin has previously reported pilot scale metallurgical test work on bulk samples (1-2 tonnes), by Bond Equipment in Klerksdorp, South Africa (refer ASX Announcement dated 15 September 2021 and the Quarterly Activities Report dated 29 October 2021). The bulk samples were from Baniaka and included DID and Soft Oxide samples from Bandjougoy.
ForThe Soft Oxide sits immediately below the DID in the geological profile (Figures 4 and 5) and is typically finer than the DID with more material reporting to be -1mm size fraction. Consequently, Lump and Fines yields are lower than achieved with DID feed, but an additional Pellet Feed product (-0.5+0.05mm) is produced. The iron grades for both Lump and Fines products from Soft Oxide sample MIN06035 (head grade 48% Fe) was 62.3%, with an overall mass yield of 45%.
or Soft Oxide sample MIN06030 (head grade 35.3% Fe), the Pellet Feed size fraction (73% of the sample mass after scrubbing), was subject to a single stage spiral rougher test and produced a concentrate before cleaning of 62.5% Fe at a mass yield of 41%. With a subsequent spiral cleaning stage to follow the rougher stage, the Fe grade is expected to further increase, through the removal of misplaced, liberated gangue.

2Drillholes included on section in Figure 4 but previously reported in the IGR in the Prospectus.
Drilling also confirmed the shallow northerly dip of the Banded Iron Formation (BIF) hosting the iron mineralisation,
and a true BIF thickness of 55 - 60m in this part of Bandjougoy.
personal
Drill hole BWDD017 intersected a fault zone (Figure 5), which is interpreted as a subvertical reverse fault. This is noteworthy in the presence of oxidised BIF at greater depth than expected, which is interpreted to represent deeper oxidation along the structure. Oxide mineralisation is encountered to vertical depths of up to 40m below surface on section BJ323000E, and up to 55m below surface along the interpreted fault on section BJ322200E.
ForThe 18 holes reported to date on 400m drill sections yield positive Oxide and Primary drill results over 2km of the 4.4km Bandjougoy prospect. The remainder of the now complete 2021 diamond program aimed at extending drilling
n 400m sections westward for the entire strike length of Bandjougoy.
The Primary BIF mineralisation remains open at depth2 on both sections and represents a strategic target to define a significant underlying magnetite asset at Bandjougoy.
2 The interpreted down-dip extent of the BIF is restricted to 1.5x nominal drill spacing in Figure 4 and Figure 5.

Bandjougoy: Context & Significance
The Bandjougoy prospect is 4.4km long with an unfolded strike extent of 6.3km of BIF and is the single largest drill target for Oxide mineralisation at Baniaka that does not currently have a Mineral Resource Estimate.
Bandjougoy does, however, have an in-situ Oxide Exploration Target of 67 million tonnes (Mt) to 124Mt grading at
35% to 49% Fe, which confirms the significance of the prospect, in addition to the following complementary criteria:

The Company's strategy is to consolidate Bandjougoy and Tsengué into a single geological model with the intent of achieving a Mineral Resource Estimate that achieves a minimum Indicated classification. This, combined with the Flouflou and Bingamba North prospects, forms the focus of activity for Mineral Resource estimations as the foundation of the Company's Baniaka Preliminary Feasibility Study.
Information regarding the Bandjougoy Exploration Target is extracted from the "Independent Geologist's Report on the Mineral Assets of Genmin
For
Limited" (IGR) authored by SRK Consulting (Australasia) Pty Ltd. The IGR is included in the Prospectus. 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.
