AKORA Achieves Premium Iron Grades Product
from further Crushing Trials at Bekisopa
Highlights
•
3mm crush delivered benchmark 62% Iron Product Grade at low impurity
levels
•
2mm crush delivers a premium 64% grade iron ore fines product
•
2mm crush achieves excellent combined silica and alumina at 5.5% with
excellent Phosphorous and Sulphur levels of 0.03%P and 0.01%S
•
Crushing finer than 2mm is not warranted due to diminishing improvements to
iron grade and impurity levels
•
Optimal crush size of 2mm will be adopted for the JORC Resource Estimation
•
These are very favourable results as a 2mm crush is less costly than a finer
crush

AKORA Resources Limited (ASX:AKO, AKORA, the Company) is pleased to report on a series
of crushing trials on 2020 drill cores taken from its flagship Bekisopa Iron Ore Project.
These processing trials continue to show excellent iron ore product grades of; 62% iron at a
crush size of 3mm and 64% iron at a crush size of 2 mm from massive and coarse
disseminated iron mineralisation types. As expected, the iron grade increases proportionally
with finer crush sizes while the silica, alumina, phosphorus and sulphur levels decrease
substantially.
Analysis of the product grades achieved from all processing trials to date, including those
reported to the ASX on 13 April 2021, 27 April 2021 and 25 June 2021, shows the iron
mineralisation along the Bekisopa strike length can deliver high grade iron products. The
excellent product grades observed from along the strike and from the northern and southern
zones, where the 2021 drill grids are planned, ranged from 60.7 to 68.3%Fe, averaging
65.2%Fe.
AKORA Managing Director Paul Bibby stated:
“Previous processing trials at 2mm and wLIMS delivered very clean fines products at
excellent iron grades and low impurity contents. This current series of process trials
at crush sizes from 3mm down to 0.25mm has achieved a benchmark product grade of
62% iron at 3mm after wLIMS with markedly improved iron grades and lower impurity
contents at finer crushing sizes.
These trials confirm that a 2mm crush delivers quality high-grade iron ore fines
products, therefore, we have decided for the JORC resource estimation to conduct
product trials on drill core samples from the 2021 drilling campaign at 2mm and wLIMS.
This series of crushing trials confirm the favorable upgrading characteristics of the iron
mineralisation at Bekisopa in achieving high-grade clean iron ore fines products.”
Crush Size Process Trials V Iron Product Grade
Previously AKORA completed 12 processing trials incorporating 2mm crushing (Note: crush
to 2mm etc implies maximum crush size is 2mm) with wet Low Intensity Magnetic Separation
(wLIMS). Ten were on composites of massive and coarse disseminated iron mineralisation
and achieved excellent high-grade clean iron product grades, averaging 62.8%Fe. Two of the
trials were on lower head grade fine disseminated iron mineralisation, average head grade of
20%Fe, and produced an iron product grade of 46%Fe. These early evaluations focused
exploration and process trials on the massive and coarse disseminated iron mineralisation
types and indicated where practical to blend in considered proportions of the lower grade
mineralisation to achieve a saleable product. The main results from the latest series of crush
size process trials are report here with the attached Appendix containing the all the details.
AKORA completed a series of crush size trails at the ALS Perth – Iron Ore Technical Center.
Crush sizes of 3, 2, 1.5, 1, 0.5 and 0.25mm were evaluated to determine the optimum crush
size to produce a saleable iron ore product.
Four composites were prepared comprising drill core intervals from along the 6km strike. Two
samples, MET20 and MET22, comprised core from weathered zone iron mineralisation
predominately massive and coarse disseminated iron mineralisation material, while the
second pair of composites, MET21 and MET23 comprised coarse and mainly fine

disseminated iron mineralisation material selected to evaluate the potential upgradability of
this finer mineralisation type, see Figure 1.

MET22 composites had an average iron head grade of 30.8%Fe composed un-weathered
iron mineralisation and contained coarse and mainly fine disseminated iron mineralisation
(grey bars).
The coarse crush trials on MET20 and 22 composites, 40.4%Fe head grade, produced
excellent iron product grades from 3 mm through to lower crush sizes, refer Figure 2. The
3mm coarse crush delivered a 62%Fe average product grade and the 2mm crush
delivered a 64%Fe high-grade iron ore fines product with low impurities.

The iron ore product grade results from crush trials at 3mm down to 0.5mm. These results
clearly demonstrate that a coarse crush of 2mm and wLIMS processing achieves a high-grade
4|Page
64% iron product and crushing to a finer size does not produce a materially better result and
is therefore not required.
Figure 3
Combined Silica and Alumina contents, for MET 20 and 22,are all competitive with currently
produced iron ore products (see ASX Announcement 25 June 2021) from a 3mm crush or
lower. At a 2mm crush a 5.5% combined Silica and Alumina content is excellent.
Crush trials reduced the combined silica and alumina head grade from around 25% to 8% at
a 3 size and 5.5% at a 2 mm crush size. The combined result of 5.5% at 2mm crush size
compares well with the previously reported processing trials and is likely to be very well
received by iron and steel makers. Interestingly these impurity levels do not decrease at a
lower crush size of 1.5 or 1 mm, further confirming that a target coarse crush size of 2mm is
all that is required to achieve benchmark or higher iron ore fines product grades with low
impurities from Bekisopa’s massive and coarse disseminated iron ore mineralisation.
Similarly, the Phosphorus and Sulphur impurity levels are low at both a 3mm crush and
improve when crushed to 2 mm, refer Figure 4. The average Phosphorus and Sulphur head
grade in these 2 mm composites were 0.10%P and 0.02%S.

(b)
Figure 4
Phosphorus content for MET 20 and 22, figure 4(a), and Sulphur contents, figure 4(b), at the
various crushing trial sizes. Both Phosphorus and Sulphur are within specification at a 3mm
crush size and reduce further at the 2 mm coarse crush size to 0.03%P and 0.01%S.
5|Page
Crush trials on the weathered MET20 and MET22 composites show that a crush size of 3mm
and 2mm are all that is required to achieve benchmark, 62%Fe, or higher-grade 64%
iron ore products with low silica, alumina, Phosphorus and Sulphur, Figure 5.
A high-grade clean iron ore product grade is what is sought after by iron and steel makers,
particularly those looking to both lower operational costs and improve environmental
outcomes, and these trials confirm suitability of the Bekisopa iron mineralisation for this
purpose after a coarse crush of 2mm.

Figure 5
Weathered composite MET22 product grades at crush sizes of , 2 and 1mm shows improving
iron grade and lower impurities at lower crush size. A 2mm crush achieves above benchmark
iron grade of 63% with low impurities.
The un-weathered MET21 and MET23 composites comprised lower iron grade intercepts from
across all 2020 drill holes with resultant average iron head grade of 30.8% as they include a
high proportion of lower grade fine disseminated iron mineralisation, refer to Figure 1 above.
These composites also had average head grade silica of 24.7%, alumina at 3.02%,
Phosphorus at 0.136%P and Sulphur at 0.53%S. The crushing trials show that a saleable
58% iron ore product grade is achieved at a crush size of 0.5mm and benchmark 62% iron
grade is achieved at a 0.25 mm (250 microns) size, refer Figure 6.
Further, the combined silica and alumina grades are competitive at this crush size while the
Phosphorus level is within specification at both the 0.5mm and 0.25mm crush sizes. The
Sulphur content in the 3mm crushed product averages 0.5%S and considered acceptable,
however, on further crushing an average grade of 0.3%S is well inside the accepted
specification, these results are included in the attached Appendix. In the operating
environment the objective would be to blend in proportions of this mineralisation type to
produce an overall higher grade iron ore product at a coarser crush size.
6|Page
Figure 6
Crushing trials on the un-weathered MET21 and MET23 composites with head grade of
30.8%Fe and comprising predominately the fine disseminated iron mineralisation shows that
a lower crushing size of 0.5 and 0.25 mm is required to produce a 58% and 62%Fe iron product
grade.
Conclusion
Crush Size Process Trials
A coarse crush at 3 mm is shown to be capable of producing a benchmark grade 62% clean
iron ore fines product.
Crushing at 2 mm achieves a high-grade 64%Fe product with low impurity elements that
should be highly sought after by iron and steel makers, particularly those striving to lower their
operating costs and improve environmental outcomes.
Lower grade fine disseminated iron mineralisation will ideally be blended with other mined iron
types to maximise the overall iron ore product grade and tonnage from the Bekisopa iron ore
project.

Composites for the crush trials were taken from 2020 drill core from along strike. MET20 and
MET22 composites were composed of weathered iron mineralisation and therefore contained
predominately massive and coarse disseminated iron mineralisation (black bars) and had a
higher head grade, averaging 40.4%Fe. MET21 and MET22 composites were composed of
un-weathered iron mineralisation and contained coarse and mainly fine disseminated iron
mineralisation (grey bars) and had an average iron head grade of 30.8%Fe.

Head grades for the composited crushing trial samples, with the averages for the combined
weathered and un-weathered composites included. Note the different head grades between
the Weathered, 40.4%Fe, and the un-weathered, 30.8%Fe composite starting materials.
The average iron grade for the MET20 and MET22 weathered composites is 40.4%, typical
silica, alumina, Phosphorus and Sulphur contents due to the weathering. The composite
samples for the un-weathered crush trials have a lower average iron grade at 30.8%, not
unexpected considering the high proportion of less than 25%Fe iron intervals and fine
disseminated iron mineralisation material included. These un-weathered composites have
slightly higher silica, alumina and Phosphorus and Sulphur head grades.
The 3mm coarse crush delivered a 62%Fe average product grade.

The iron ore product grade results from crush trials at 3mm down to 0.5mm. These results

The combined Silica and Alumina contents for the 3mm crush test at 8% is competitive with
currently produced iron ore products (refer AKORA ASX Announcement June 28th 2021). The

Crush trials on the weathered MET20 and 22 show that a crush size of 3mm and 2mm are

with low silica, alumina, Phosphorus and Sulphur.

Crush Size Process Trials – Un - Weathered iron mineralisation.
Composites MET21 and 23 from un-weathered coarse disseminated and fine disseminated
iron mineralisation types achieved product grade after a; 0.5mm crush and LIMS achieved a
58%Fe clean product grade and at a 0.25mm crush and LIMS achieved a 62%Fe product
grade with lower impurities.
It is expected that these lower iron grade and fine disseminated iron mineralisation type
material will be best to be blended so as to achieve saleable iron ore products from an
operational mine. Following are the complete results from these latest crushing trials.
The un-weathered MET21 and MET23 composites comprised lower iron grade intercepts from
across all 2020 drill holes with resultant average iron grade of 30.8%, and they include a high
proportion lower grade fine disseminated iron mineralisation type, refer to Figure A1. The
crushing trials show that a saleable iron ore product grade at 58%Fe can be achieved at a
finer crush size of 0.5mm and benchmark 62% iron grade is achieved at a 0.25mm or 250
microns size, refer Figure 7.
Figure A7
12 | P a g e
Crushing trials on the un-weathered MET21 and MET23 composites with head grade of

a lower crushing size of 0.5 and 0.25mm is required to produce a 58 and 62%Fe iron product
grade.

Sulphur content in the 3mm crushed product averages 0.5%S and considered acceptable, on
further crushing an average grade of 0.3%S is inside the accepted specification, refer Figures

Un-weathered composite MET21 and MET23 products at crush sizes of 2 and 1mm. Product
grades at crush sizes of 0.25mm averaged 62%Fe with low impurity levels. Expectation would
be to blend this iron mineralisation type with other higher grade material to achieve a saleable
product at a coarser crush size or 2mm.
Crushing trials on the low grade un-weathered fine disseminated iron mineralisation shows it
can be upgraded, by >100%, to a 62%Fe product after crushing to 0.25mm or 250 microns.
In the operating environment the objective would be to blend proportions of this mineralisation
type to produce a higher grade iron ore product. If a 250 micron process stage was necessary
this would be some 6 to 10 times coarser than required for other comparable grade magnetite
deposits that need fine grinding processes at 25 to 45 microns to delivering a saleable iron
product at low impurity levels.

o Ground magnetic surveying (305 line kilometres);
o The 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:
o Weathering of a typical Algoma style magnetite-quartzite type banded iron
formation (BIF); or
o More 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.

Commentary
• The bands and blebs of massive magnetite aggregates along with preliminary LIMS testwork
suggest that a good iron product may be obtained using a simple crush to -2mm followed by
magnetic separation.
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 metres) of the drill hole
collar;
o Dip and azimuth of the hole;
o Down hole length and interception depth;
and
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.

Commentary
• Geological interpretation and cross sections of drillholes BEKD01 to BEKD08 are presented in the
associated press release.
• Significant assay results are included in the attached press release.
Data
aggregation
methods
• In reporting Exploration Results, weighting
averaging techniques, maximum and/or
minimum grade truncations (eg 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.
• No cuts were used as iron is a bulk commodity.
Relationship
between
mineralisation
widths
and
intercept
lengths
• These relationships are particularly important in
the reporting of Exploration Results.
• If the geometry of the mineralisation 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 (eg ‘down hole length, true width
not known’).
• The cross sections in the associated press release clearly show the relationship between downhole
mineralisation width and true width. This varies from the intercepts being approximately true
width to the intercept widths being approximately 1.5 times the true width. Some of the true
widths are still not clear and require additional drilling to confirm dips but dips are generally steep
(60-80°W) in the north and shallow (20-40°W) is the south.
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
•
A plan and interpreted cross sections are included in the associated press release that clearly
show the relationship of the drilling to the mineralisation.
