Bekisopa Maiden Mineral Resource
Highlights
Northern & Central Zones Inferred Resource:
-
43.3 Mt Inferred Resource in the Northern Zone
-
✓ 43.3% Davis Tube Recovery (DTR), average head grade 33.3%Fe,
-
✓ 68.2%Fe concentrate grade at a 75-micron grind size
-
41.2 Mt Inferred Resource in the Central Zone
-
✓ 36.3% DTR from an average head grade of 30%Fe
-
✓ 67%Fe concentrate grade at a 75-micron grind size
-
Southern Zone Exploration Target 50-100Mt (average head grade 25-40%) (Mineral Resource to be reported on when outstanding analysis is completed, see Cautionary Statement below)
-
Northern & Central Zone Inferred Resource & Southern Zone Exploration Target are the result of drilling on only 1/3 of tenement strike length
-
H&S Consultants concluded high-grade outcrop material and the highgrade weathered zones can be selectively mined using conventional shovel, truck, crush and screening operations to produce lump and fines DSO
Commenting on the Resource Estimate AKORA Resources Managing Director,
Paul Bibby, commented that: “This Maiden Resource for only the Northern and Central Zones at 84.5 million tonnes is outstanding given the limited drilling in these areas. As some analysis work in the Southern Zone is still to be completed, H&S Consulting has advised of an Exploration Target of 50 to 100Mt for the Southern Zone at similar concentrate grades. This means the Company has significantly exceeded its initial expectation in the 2020 Prospectus. When all is reported, including the Southern Zone and an assessment of the DSO potential, this will confirm a significant first resource from drilling on only 30% of the 6-kilometer strike at Bekisopa. The potential for significant additional tonnage cannot be underestimated, this is an extremely positive result, achieved within 15 months of listing.”
Cautionary Statement
The board of directors wish to inform shareholders that an Exploration Target is conceptual in nature and accordingly, there has not been sufficient exploration to estimate a Mineral Resource and that further exploration will result in an estimation of a Mineral Resource.
AKORA Resources (“AKORA” or “the Company”) (ASX Code: AKO ) is pleased to provide shareholders with the maiden Mineral Resource for the Northern and Central Zones of the Bekisopa project. Mineral estimation results for the Southern Zone will be reported as soon as complete, the delay due to the late receipt of the final assay and processing trial results.
At the time of preparing the AKORA Resources Prospectus and budgets the Company forecast a 100 million tonnes maiden Mineral Resource from the first 4,000 metres of drilling at Bekisopa. As drilling success progressed it was decided to bring forward additional drilling planned for 2022 into the 2021 campaign to minimize costs and maximise the size of the initial Mineral Resource. The Northern and Central Zones comprise 25 drill holes for some 2,142 metres from a total of some 6,200 drilled metres, and has delivered an 84.5 million tonnes Inferred Resource , exceeding expectations.
The “Maiden Resource Estimates, Bekisopa” report prepared by Mr Simon Tear, H&S Consultants Pty Ltd is attached to this announcement and details the sampling and assaying methodology, the resource estimation procedure and details resource tonnages and recovered magnetic fraction grades.
Figure 1 shows the magnetic anomaly that defines the 6-kilometre strike length on the main Bekisopa tenements and drill hole locations for all drill zones. This shows that only some 30% of the strike length has been drilled, further drilling should expand the resource considerably.

Work continues on delivering the Southern Zone Mineral Resource Estimate for which H&S Consulting has indicated an Exploration Target of 50 to 100 million tonnes at an estimated concentrate grade of:
-
67% to 69%Fe at a 30% to 45% DTR with
-
1-2.5% SiO2, 0.2-1.2% Al2O3, 0.001- 0.01 % P2O5, 0.01-0.02% S & -1 to - 2.5% LOI.
H&S Consulting have also noted that “the high-grade outcrop material and the highgrade weathered zones can be selectively mined using conventional shovel, truck, crush and screening operations to produce lump and fines DSO.” These outcomes will be reported on as soon as completed.
Conclusion
The maiden Inferred Resource for the Bekisopa Northern and Central Zones have exceeded expectation at 84.5 million tonnes at a concentrate grade of 67.6%Fe, which represents a premium grade product suitable for Direct Reduced Iron pellet feed demanded for the Green Iron and Steel de-carbonised future.
The Exploration Target for the larger Southern Zone has been estimated by H&S Consultants, as 50 to 100 Mt @ 30% to 45% DTR for a total of 20 to 50Mt of magnetite with a concentrate grade of 67% to 69% Fe, ( see Cautionary Statement in relation to the Exploration Target at the commencement of this Announcement).
It is anticipated that once the final DTR assay results have been received, the Mineral Resources for Bekisopa will be updated to include the Southern zone. In addition, the
update is expected to include the definition of the potential Direct Shipped Ore material.
This extensive maiden Mineral Resource confirms the AKORA Board’s decision to list the company and accelerate the drilling campaigns. The result confirms that Bekisopa is a significant iron ore resource that could deliver high-grade fines and concentrates at relatively coarse sizings after a start-up focused on the high-grade outcrop and weathered zone iron ore.

Maiden Resource Estimates, Bekisopa, Madagascar
H&S Consultants Pty Ltd (“H&SC”) was requested by Akora Resources Limited (“AKO”) to complete maiden resource estimates for the Bekisopa Iron Ore Project in southern Madagascar. The target commodity is iron mineralisation as massive magnetite with a secondary option of nearsurface direct shipping oxidised iron material. In 2021/2 AKO drilled 64 diamond exploration holes for approximately 6,212.5m and 3,930 samples on the Southern, Central and Northern target areas, part of a continuous belt of magnetite mineralisation stretching for 5.5km of strike. Due to a significant backlog at the analytical laboratory final results for recovered magnetic fraction are not available for the Southern deposit and hence Mineral Resources are only reported for the Central and Northern deposits. These estimates have been reported in accordance with the JORC 2012 Code and Guidelines. Additional details and maps are supplied in Appendix 1.
The project is located within Paleoproterozoic age rocks in south central Madagascar. The local geology consists of a calc-silicate unit within schists and gneisses. The calc-silicate unit appears to have been a favourable host for deposition of iron mineralisation from metasomatic fluids derived from either magmatic or metamorphic processes. As is normal for high grade metamorphic rocks, the units show evidence of complex deformation including several generations of folding. There is some evidence of an early isoclinal folding and this can be seen in both outcrop and regional scales. The iron mineralisation does not appear to be isoclinally folded but is affected by a later open folding event as seen on the cross sections. The iron mineralisation occurs dominantly as magnetite although some hematite is noted, in particular within near surface environments suggesting this may be due to later alteration/oxidation. A few instances of hematite are also noted in unweathered rocks but this is rare and may be related to alteration around fault zones. The mineralisation has the form of a tabular zone or zones and trends from steeply westerly dipping in the north to moderately westerly dipping in the centre and flat dipping in the south. Faulting is not apparent on a large scale but may be present on a smaller scale that has not been identified with the current drill spacing. Oxidation is variable but generally complete oxidation is between 5 and 20m below surface and partial oxidation (generally around fractured zones only) is variable. There has been some iron

enrichment in the oxidised zone due to removal of host rock material via weathering and there is some potential for direct shipping ore (“DSO”).
AKO has supplied the drillhole databases for the deposit, which H&SC has accepted in good faith as an accurate, reliable and complete representation of the available data. H&SC performed very limited validation of the data but did not detect any obvious problems likely to impact significantly on the resource estimates. The drillhole database for Bekisopa is satisfactory for resource estimation purposes; however, responsibility for quality control resides solely with AKO.
Drill spacing was nominally 200m by 100m in the Northern target area, 200m by 50m in the Central target area and 150m by 50m in the Southern target area. The drilling technique and hole spacing is considered appropriate for the style of mineralisation and the generation of Mineral Resource estimates. Core recovery for the HQ/NTW drilling averaged about 95-96% with no significant relationship between iron grade and recovery. All drillholes were surveyed downhole every 10m using a Reflex EZ-Gyro gyroscopic multi-shot camera. No excessive hole deviations have been recorded. The hole collars were located by DGPS to sub-centimetre accuracy and the topography survey was conducted using PHANTOM 4 Pro type drones, and a pair of LEICA System 1200 dual frequency GPS. An accuracy of 10mm horizontal and 20mm vertical is quoted.
A set of standard operating procedures for drilling and sampling were prepared by the AKO and Vato Consulting, who supervised the programme, and these were always adhered to. All drill core was logged quantitatively using industry standard practice on site in enough detail to allow mineral resource estimates as required. Logging included core recovery %, primary lithology, secondary lithology, weathering, colour, grain size, texture, mineralisation type (generally magnetite or hematite), mineralisation style, mineralisation %, structure and magnetic susceptibility. All core was photographed both wet and dry and as both whole and half core. All core was geotechnically logged and RQD’s calculated for every sample interval. All drill-holes were logged using a magnetic susceptibility meter to enable accurate distinction of iron (magnetite) rich units and to potentially differentiate between magnetite and hematite-rich mineralisation. Density measurements were made using both the weight in air/weight in water (Archimedes method) for mainly fresh rock and the Caliper Vernier method for mainly regolith material.
Sampling consisted of sawn half core under geological control and measured hand-held magnetic susceptibility levels. Sample intervals ranged from 0.33m to 2.84m in length with an average length of 0.84m. The half core sample intervals were put into polythene bags along with a paper sample tag. This was then sealed using a cable tie and placed into a second polythene bag with a second paper tag and this was sealed using staples. The samples were subsequently transferred at regular intervals to the commercial sample preparation facility in Antananarivo (OMNIS) where they underwent sorting and weighing, drying at 110-120°C until totally dry and then weighed, jaw crushed to 2mm, riffle split (1:1) with one half kept as reference. A sub-sample of 100g with 80% passing 2mm was pulverised to minus 75 microns and sent for chemical analysis at a commercial

laboratory. The sample prep procedure is to industry standard. Residual material from the various sample prep stages are stored for future reference. Sample analysis comprised head assays using the XRF technique for the “Iron Ore Suite” at ALS in Perth and Ireland, with the recovered magnetic fraction analysis completed using a Davis Tube (“DTR”) and XRF analysis of the DTR fraction ie concentrate grades. The sample prep, sample sizes and analytical techniques are considered appropriate for the style of mineralisation and the commodity sought.
QAQC comprised standards, blanks and duplicates with blanks inserted every 40[th] sample, likewise for the standards with lab duplicates inserted at a rate of 2 to 4 per 100 samples. The QAQC programme is to industry standard. The QAQC results indicate no issues with the sampling or assay data.
The geological interpretation for the Mineral Resources was completed on appropriately spaced cross sections for each target area ie 200m for the Central and Northern deposits and 150m for the Southern deposit. A series of strings snapped to the drillholes were used to create a series of surfaces and solids, these included a main mineral zone and subordinate footwall lodes, 2 for the Central zone and 1 for the Northern zone along with surfaces representing the base of high grade oxidised surface mineralisation (“DSO”), the base of regolith/base of complete oxidation and the base of partial oxidation. Design of the mineral solids were based on a combination of logged geology and the sampling with additional input from DTR/head iron grades (nominal DTR cut off of 6-8% was used where data was available). The high grade zone surface was based on proximity to the topographic surface and a nominal head grade iron cut-off grade of 55-60% Fe in conjunction with geological sense. The other oxidation surfaces were based on logged geology, sulphur head assays and geological sense.
Metal grade interpolation used Ordinary Kriging on 570 2m composites for the two areas under consideration. Composites for the mineralisation were extracted from the drillhole database constrained by the mineral wireframes. Elements modelled included DTR and head Fe grades along with concentrate Fe, SiO2, Al2O3, P, S, TiO2 and Loss on Ignition (“LOI). No top cuts were applied to the data due to the relatively low coefficients of variation for each element, generally <0.5, and relatively well-structured data. The distinct high grade surface mineralisation was modelled separately to avoid smearing high grades into the main body of mineralisation.
Block models were orthogonal to the national grid with block sizes for both deposits being 25m by 50m by 5m (X, Y & Z) with no sub-blocking. A 3 pass search strategy was employed for both deposits using initial search radii of 200m by 300m by 20m with a minimum number of 12 data and 4 octants. The search ellipse was expanded to 300m by 450m by 30m with the same number of minimum data and octants and then completed with the same search radii but with a minimum of 6 data and 2 octants. One search domain was used for the Central area and two for the Northern area reflecting a modest change in strike. The wireframe boundaries for the mineralisation act as hard boundaries.

Density data for the three deposits comprised 5,451 measured values from single selected pieces of drillcore, 10-15cm in length. 2,661 samples were from the partially weathered and fresh rock zones with the remaining samples from the regolith and weathered surface material. Density data for the Central and Northern deposits, 904 and 1,482 samples respectively, was modelled unconstrained using Ordinary Kriging on the sample data. Search parameters were relatively similar to the parameters used for the metal grade interpolation with an additional larger search to ensure the generation of modelled block grades peripheral to the mineralisation.
Block model validation consisted of visual inspection of drillhole assays, composites and block grades in section, statistical comparison of composite values with block grades and grade-tonnage curves. No significant issues were noted.
The new Central and Northern resource estimates are reported from within the relevant mineral wireframes/below the topographic surface, exclusive of the DSO material, using a 15% DTR cut off on a centroid in/out basis. The cut off grade was advised by AKO following its analysis of the assay results and is similar to cut off grades used for similar types of deposits.
The Mineral Resources are classified as Inferred. The classification of the resource estimates is derived from the data point distribution (i.e. the drillhole spacing) with due consideration to other factors like grade continuity (variography), geological understanding and continuity including surface mapping, drilling method and recovery, QAQC and density data. The positive aspects for the resource classification are the geological model, the use of diamond core with >95% recovery, appropriate sampling, sample perp and analytical techniques with appropriate QAQC. The negative aspects for the classification are the are the wide drillhole spacing and the relatively poor variography, the style of mineralisation and the apparent lack of good grade continuity (implies more detailed drilling is required) and the lack density date for the oxidised zones.
The combined Mineral Resource for the Central and Northern deposits of the Bekisopa Iron Ore project are detailed below, along with the concentrate grades of the magnetite product (grind size 75 microns).

H&SC has assumed the deposits will be extracted by an open pit bulk mining method.
From the geological surveying, drilling campaign assaying and numerous product processing trials there are three potential products from within and across the Bekisopa prospect. Firstly, the highgrade outcrop material and the high-grade weathered zones can be selectively mined using conventional shovel, truck, crush and screening operations to produce lump and fines DSO. Secondly, bulk mining of the iron mineralisation between 30 to 55%Fe head grade and subjecting the material to crushing and screening to a 2mm size followed by magnetic separation to produce a +62%Fe fine product. Thirdly, bulk mining of the iron mineralisation at a nominal +15%Fe head grade using conventional mining practices and then crush and grind to ~75-microns and apply magnetic separation techniques to produce an iron concentrate product grading +67%Fe with the possibility of using higher iron head grades, nominally 25 to 45%Fe, to generate a +69%Fe concentrate feed product, both suitable for Direct Reduction Iron processes.
The Bekisopa project in south central Madagascar is a flat to gently undulating remote and isolated country area of semi-arid grassland.
Future work should comprise a substantial amount of infill drilling to upgrade the Mineral Resources.
Exploration Potential
Exploration potential consists of three components:
1] The new Mineral Resources and the likely mineralisation associated with the Southern area represent approximately 2km of strike of a 5km long zone of magnetite mineralisation. This allows for additional exploration potential along strike for some further 3km of mineralisation. No Exploration Target has been defined
2] Exploration potential exists within the mineral wireframes for the Central and Northern deposits where there has been insufficient drilling to generate data to produce interpolated block grades. An Exploration Target has been identified based on the geological interpretation for both deposits in conjunction with the drilling results, the surface mapping and the magnetic imagery of

20 to 40 Mt @ 30 to 45% DTR for a total of 10 to 20Mt of magnetite with a concentrate grade of
67 to 69% Fe, 1-2.5% SiO2, 0.2-1.2% Al2O3, 0.001- 0.01 % P2O5, 0.01-0.02% S & -1 to -2.5% LOI
The potential quantity and grade of the Exploration Target referred to above is conceptual in nature, as 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.
3] Mineral Resources for the Southern deposit will be reported as a soon as possible once the final DTR assays are available and the data processed in accordance with the appropriate resource estimation methodology. At this stage there is an identified Exploration Target for the Southern deposit based on the drilling results, the surface mapping and the magnetic imagery of:
50 to 100 Mt @ 30 to 45% DTR for a total of 20 to 50Mt of magnetite with a concentrate grade of
67 to 69% Fe, 1-2.5% SiO2, 0.2-1.2% Al2O3, 0.001- 0.01 % P2O5, 0.01-0.02% S & -1 to -2.5% LOI
The potential quantity and grade of the Exploration Target referred to above is conceptual in nature, as 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.
