AKORA DELIVERS FURTHER OUTSTANDING DRILL RESULTS WITH IRON ORE PRODUCT GRADES UP TO 66.9% FE
All assay and processing trial results for drill holes 9 to 12 from the 2020 drilling programme have been received and show outstanding intersections and product grades for the southern area of the Bekisopa Iron Ore Project.
Highlights – Assay Results
-
Assays confirm continuation of significant, near surface, high-grade iron mineralisation in a shallow dipping mineralisation zone and confirms 4km strike
-
Iron mineralisation is outcropping and is at least 45m true thickness, across three drill holes (BEKD9-BEKD11), and importantly increasing in thickness with depth.
-
Significant continuous iron mineralisation intercepts from surface, with 25.2m @ 61.4% Fe including 13.6m @ 63.5% Fe
Highlights – Processing Results
-
Iron mineralisation in the southern area upgrades extremely well at a coarse crush size of minus 2mm.
-
Product grades up to 66.9%Fe achieved after crushing to minus 2mm and wet low intensity magnetic separation (LIMS), with potential for a high quality premium DSO fines product
-
Iron recoveries up to 90.6% with average mass yields of 70% for the massive magnetite
-
Like the northern and central areas previously reported (See ASX Announcement dated 13 April 2021), drilling has confirmed continuity of iron mineralisation at depth in the southern area, with thickness increasing to the west.
-
The next ~4000m drilling campaign is designed to deliver an initial resource estimate reportable under JORC guidelines and is expected by the end of 2021;
AKORA Resources Managing Director, Paul Bibby commented on the results, “Assays for the final 4 drill holes of the 12-drill hole programme conducted in 2020 have been received and clearly indicate the significant potential for Bekisopa to be a high-grade iron ore project.”
“The results show extensive iron mineralisation intercepts from surface with mineralisation increasing in thickness with depth. The laboratory results again show that the Bekisopa project has the potential to deliver an extremely high-grade iron ore product. The product grade of 66.9% Fe is outstanding along with the excellent iron recovery at 84%. More importantly, the Bekisopa product results have been achieved after only minimal processing by crushing to 2mm followed by magnetic separation. The final product grade is exceptional and believed better than comparable iron ore projects. Our outlook for the coming JORC Resource estimate is very positive and we will continue to deliver on our stated strategy to progress Bekisopa toward a significant high grade, low-cost iron ore project.”

Introduction
Akora Resources Limited (ASX: AKO) is pleased to report on the remainder of the assay results delivered from the drilling campaign conducted in 2020 (see ASX Announcement, dated 17 December 2021) following on from results from the first 8 drill holes reported in 2021 (see ASX Announcement, dated 13 April 2021).
The laboratory results from the remaining 4 drill holes at Bekisopa (drill holes 9 to 12), all located in the southern area of the project, have been received for both the chemical assay and mineral processing (Low Intensity Magnetic Separation (LIMS) test work). The laboratory analytical analysis was completed respectively by ALS Laboratories in Ireland and Western Australia.
The results confirm the previous interpretation of a broad, shallow (15°) westerly dipping iron mineralised zone with a true thickness of at least 45 metres, increasing to the west. The mineralised zone outcrops and is continuous from surface. Simple coarse crushing and wet LIMS test work generated outstanding recoveries of up to 90.6%Fe and delivered product grades of up to 66.9%Fe. These final laboratory results confirmed the excellent qualities of the Bekisopa mineralisation and highlight the potential for low capital and operating costs and high-grade iron ore product.
Discussion
In summary, the drilling has confirmed the previous interpretation of an outcropping zone of massive and coarse disseminated magnetite +/- hematite in the southern area of the project area, starting at surface and continuous to the limit of drilling to date (see Figures in Appendix 1). The mineralisation corresponds with the magnetic anomalies set out in the plan in Appendix 1 (ie., the stacked profiles of total magnetic intensity). The magnetics data suggests semi-continuous mineralisation over at least 6km strike with drilling to date confirming 4kms of this strike length.
The new results show very high-grade massive mineralisation is present in each of the lateritised surficial, totally oxidised weathered, transitional and fresh rock zones. This outcome clearly suggests the potential for large scale mineralisation at depth and to the west.
The modelling from the ground magnetic survey has been proven by the drilling programme and the drilling campaign proposed for this year will enable the Company to deliver a JORC resource by the end of the year.

The locations, cross sections and assay intervals are shown on the plan and cross sections in Appendix 1 whilst drill hole details and other element assays are shown in Appendix 3.
The drill core chemical analysis, field testing and observations, in combination with the drill core intercepts, confirm the following:
-
There is a broad, shallowly dipping iron mineralised zone with a true thickness (including eroded parts) of at least 45 metre, across drill holes 9, 10 and 11 in the south of the permit area, with intersection averages between 39% and 59% Fe
-
Drillhole BEKD12 did not intersected significant mineralisation and suggests the mineralisation may be dipping to the east rather than to the west in this area (see figure in Appendix 1) and therefore, this location remains a valid target
-
There is a slight elevation in grade within the weathered zone, probably due to weathering of the country rock. This is illustrated by the general increase in average grade at shallower depths (see cross-section in Appendix 1)
-
There are several bands of massive magnetite-hematite, which grade greater than 60%Fe, in both oxidised and fresh rock:
3 | P a g e
-
25.2m @ 61.4% Fe in the oxidised (lateritised) zone in drillhole BEKD11
-
o13.6m @ 63.5% Fe in transition zone in drillhole BEKD11 -
3.2m @ 61.3% Fe in the oxidised (lateritised) zone in drillhole BEKD10
-
3.9m @ 63.6% Fe in the transition zone in drillhole BEKD10
-
The massive mineralisation continues at depth
-
The iron mineralisation tested to date in the south of the permit area has been confirmed as being relatively flat lying, dipping at about 15° to the west as shown on the cross-section in Appendix 1.
-
Total true width is currently shown to be at least 45m in the southern area tested to date (including eroded parts) and appears to be increasing in thickness to the west
-
Preliminary mineral processing test work on the southern area indicates mineralisation is capable of producing a high-grade iron ore product grading up to 66.9%Fe (average 66.5%Fe) from the massive magnetite at a relatively coarse crush size of 2mm
-
Wet LIMS trials recovered up to 90.6% of the iron (average 78%) for a mass recovery of 70% from the massive magnetite iron mineralisation
-
The Company proposes to conduct additional processing trials to maximise the iron content and recovery in the product fraction by recovering hematite and goethite that appears to remain in the non-magnetic fraction
Mineral Processing
First pass mineral processing test work was conducted at the ALS Iron Ore Technical Centre in Perth to examine the processing characteristics of the iron mineralisation. These unoptimized trials were performed on various crushed splits from the drill core extracted during the crushing process for preparing the analytical pulps.
Splits were collected after the core was crushed to minus 10mm to simulate a potential lump product, and then after the core was crushed to minus 2mm. The 10 and plus 2mm samples were treated using the LIMS equipment in the dry mode, which effectively separates the feed material into magnetic and non-magnetic fractions using a drum magnet. The minus 2mm LIMS test were conducted in the wet mode.
The minus 2mm fractions from the southern area (massive and coarse disseminated mineralisation) returned excellent results as shown in the table below:

Magnetic fraction, -2mm, 900 gauss magnetic drum separation, wet LIMS (Est Head = head grade estimated from combination of individual samples, Calc Head = head grade back calculated from combined magnetics and non-magnetics assays)
The first pass, unoptimized processing results are outstanding and indicated that the mineralisation should be readily upgraded to a DSO fines product through conventional crushing to minus 2mm and magnetic separation.
It is important to note that the Bekisopa magnetite mineralisation is very different from that seen elsewhere. Australian BIF magnetites are energy intensive as the magnetite is required to be ground to less than 50 microns to produce a product grade equivalent to that at Bekisopa. The Bekisopa DSO fines product has very low phosphorous (0.03-0.06% P), low SiO2 and low Al2O3.
The iron recoveries are excellent, even for the surficial lateritised material, and it appears that some iron is reporting to the non-magnetic fractions due to being in the form of much lower magnetic intensity minerals hematite and goethite, as suggested by the iron assays of the non-magnetic fractions varying from 14.4% Fe to 55.9% Fe (average 33.9%). Further testing will be performed to maximise recovery of these iron fractions into the iron ore product stream.
The high-grade magnetic products are shown as Figures 1 to 4.

Conclusions
Assay results from the drilling in southern area of Bekisopa has shown significant near surface high-grade iron mineralisation extending at depth.
This massive magnetite mineralisation readily upgrades to a 66% iron, a premium grade iron ore product, after only crushing to minus 2mm and magnetic separation, these are outstanding outcomes.

The metallurgical test work again generated an outstanding iron product grading 66.9% Fe at 83.9% Fe recovery and at a 75.3% mass yield from a simple 2mm crush followed by magnetic separation.
The phosphorous was low with most of the P reporting to the non-magnetic fraction. Silica and alumina were both low and sulphur is also low at 0.01%, probably due to weathering of any sulphides present.

Again, the metallurgical test work generated an outstanding iron product, grading 65.1% Fe at 58.9% Fe recovery and mass yield at a 55.1% from a simple 2mm crush followed by magnetic separation. The phosphorous was low with most of the P reporting to the non-magnetic fraction. Sulphur was low in this sample at 0.15%, probably due to weathering of any sulphides present.
The non-magnetic product from this LIMS trial is high in iron, suggesting a component of the less magnetic hematite and/or goethite may be present. Mineralogy and further test work will be performed to determine how to effectively capture these iron minerals into the saleable product.
BEKMETF12
This sample is a composite from logged coarse disseminated mineralisation from the southern area. It was collected from oxidised and transitional drill core, grading to slightly weathered in places.
Approximately 100g of individual samples were combined into a single combined sample with an estimated head grade of 40.8% Fe using the average of individual samples used:

The tenure was acquired by AKO during 2014 and work since then has consisted of: |
| mineralisation. | oData compilation and interpretation; |
||
oConfirmatory rock chip sampling (118 samples) and mapping; |
|||
oRe-interpretation of airborne geophysical data; |
|||
oGround magnetic surveying (305 line kilometres); |
|||
oThe current programme of 1095.5m diamond core drilling in 12 drill-holes. |
|||
| • | There was until recently debate as to which of the following two options the near surface | ||
| mineralisation is due to: | |||
oWeathering of a typical Algoma style magnetite-quartzite type banded iron |
|||
| formation (BIF); or | |||
oMore closely reflects the actual mineralisation at deeper levels and is only |
|||
| moderately altered by weathering effects, such as converting some of the | |||
| magnetite to hematite and/or limonite-goethite. | |||
| • | The recent drilling has shown beyond doubt that the second of these is in fact the case, with | ||
| at most a 25% increase in grade due to weathering effects. However, it should be noted that | |||
| some downslope creep of scree from these units may exaggerate apparent width at surface. | |||
| • | The mineralisation occurs as a series of magnetite bearing gneisses and calc-silicates that | ||
| occur as zones between 50m and 150m combined true width. | |||
| • | The mineralisation occurs as layers of massive magnetite (sometimes altered to hematite) | ||
| between 1m and 7m true width plus a lower grade zone that consists of lenses, stringers, | |||
| boudins and blebs of magnetite aggregates that vary from 1cm to 10’s of cm wide within a | |||
| calc-silicate/gneiss unit (informally termed “coarse disseminated” here). These units | |||
| sometimes have an outer halo of finer disseminated magnetite (informally termed | |||
| “disseminated” here). | |||
| • | This wide mineralisation halo provides a large tonnage potential over the 6-7km strike of | ||
| mapped mineralisation and associated magnetic anomaly within the Akora tenement. |
