------------------------------------------------------------------------------------------------------------Australian Securities Exchange Announcement 13 October 2020

-------------------------------------------------------------------------------------------------------------

King River Resources Limited (ASX: KRR) is progressing the Speewah Prefeasibility Study (“PFS”) on the company’s 100% owned Speewah Specialty Metals (“SSM”) Project in the East Kimberley of Western Australia. The KRR PFS has retained a Kimberley focus that would produce High Purity Alumina (HPA), with any future potential co-products Vanadium (V2O5), Titanium (TiO2) and Iron (Fe oxide) not included in this initial study.

Following the KRR ASX release 7 September 2020, further significant PFS developments have been the focus of testwork and studies:

  • KRRs metallurgical testwork using its simplified purification process has produced a high purity precursor compound with the main contaminant metals (Na, K, Si, Fe, Ca, Mg and Ga) each at very low levels (about 1ppm or less than 1ppm). This precursor (see photograph below) may be suitable for the production of 4N (99.99% Al2O3) HPA after calcination (heating to 1200°C) and washing. These very low (±1ppm) contaminant levels are required because on calcination the mass (and volume) of the precursor is significantly reduced due to off-gassing of volatile elements, which causes the levels of contaminants to increase in the final HPA calcined product.

High Purity Precursor Compound
----- End of picture text -----

  • Calcination of the HPA precursor (at 1200°C) is the current focus of testwork to ensure no contamination is introduced during the heating process and 4N (99.99% Al2O3) HPA is produced.

  • The first batch of HPA samples of different alumina grades produced in previous test runs has been submitted to an independent umpire laboratory to provide greater confidence in testwork assays and help identify sources of contamination in the testwork.

  • CSA Global has updated the Mining Study based on the simplified flowsheet with improved overall recovery and lower throughput.

==> picture [595 x 87] intentionally omitted <==

  • CRU International is finalising the HPA market study to a 2028 dateline.

  • Como Engineers is working on completing the process plant and infrastructure design and costings based on the updated flowsheet and the final production of 4N HPA.

The Company aims to release the PFS as soon as practicable on completion of these remaining outcomes. In parallel with completing the PFS outlined above, the Company is continuing to progress metallurgical testwork and engineering studies using our HPA process route on alternative aluminium feedstocks. Testwork has demonstrated that a high purity HPA precursor can readily be made with fewer process steps. The implication is that start up HPA development may be initially focused around a Perth industrial estate, without the immediate capital and permitting needs of building a Kimberley based acid plant adjacent to a mining and processing operation.

This announcement was authorised by the Chairman of the Company.

Appendix 1: King River Resources Limited Speewah Project JORC 2012 Table 1

SECTION 1 : SAMPLING TECHNIQUES AND DATA

Criteria JORC Code explanation Commentary
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 down hole 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.
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 1 m
samples from which 3 kg was pulverised to produce a 30 g 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.
This ASX Release dated 13 October 2020 provides an update on the Speewah HPA
Prefeasibility Study including some hydrometallurgical processes involved in the production of
high purity alumina (HPA) from the high grade zone of the Central Vanadium deposit at KRR’s
Speewah Project (Figure 1).
Diamond Core Sample
16 HQ and PQ diamond drill (DD) core holes were drilled in the Central Vanadium deposit (see
Figure 2 and Table 1 for locations).
Three PQ holes have been used in beneficiation and leaching metallurgical testwork by Nagrom
(SDH11-09, SDH11-06 and SDH11-12, Figure 2).
Three of the PQ core holes from the high grade zone (SDH11-09, SDH11-12 and SDH11-12)
have been used in the hydrometallurgical metallurgical testwork.
For example, Nagrom received a 168kg composite magnetite gabbro sample of PQ ½ core from
the high grade zone of drillhole SDH11-12 – 18.2m-38.6m downhole. The head grade of this
sample is 0.351% V2O5, 3.45% TiO2, 20.665% Fe2O3, 13.243% Al2O3, 9.10% CaO, 4.469% MgO
and 44.591% SiO2.
Leachate Sample
TSW Analytical Pty Ltd has used a 3L composite of leachate solutions (designated AVL69,
AVL71 and AVL73) produced by Nagrom by leaching a 0.15mm non-magnetic concentrate
sample from the high grade zone of SDH11-06, SDH11-09 and SDH11-12.
The leach liquor typically assays 16110mg/L Fe, 11455mg/L Al, 4123mg/L Mg, 941mg/L Ti,
91mg/L V, 2248mg/L Na, 576mg/L K, 270mg/L Ca, 156mg/L Mn, 141mg/L P and 48mg/L Si.
Chemical precipitation and recrystallisation purification methods have been used in the
separation and precipitation of the high purity Aluminium precursor compound reported in this
announcement.
The Precursor compound is then calcined to high purity alumina product.
The process and reagents used are commercial-in-confidence.
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 (NQ and HQ3 size) drilling were completed to support the preparation of the Mineral
Resource estimate. Holes drilled vertical.
Metallurgical testwork has been completed on ½ PQ core composite sample from metallurgical
diamond drill core holes SDH11-09, SDH11-12 and SDH11-12 (Figure 2 and Table 1):
Drill sample
recovery
Method of recording and assessing core and chip sample recoveries
and results assessed.
No qualitative recovery data was recorded. Qualitative examination and photography suggested
RC and diamond recoveries are very high. Good ground conditions exist which suggests
recovery is likely to be very high.
Measures taken to maximise sample recovery and ensure
_representative nature of the samples. _
PQ drilling was used to maximise diamond sample recovery.

==> picture [842 x 92] intentionally omitted <==

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.
No relationship between grade and recovery has been identified.
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.
DD core and RC chips were geologically logged, with descriptions of mineralogy and lithology
noted.
Whether logging is qualitative or quantitative in nature. Core (or
costean, channel, etc.) photography.
Logging was generally qualitative in nature. DD core photographed wet.
The total length and percentage of the relevant intersections logged. SDH11-09, SDH11-12 and SDH11-12, all 100% logged.
Sub-sampling
techniques and
sample
preparation
If core, whether cut or sawn and whether quarter, half or all core taken. DD core was cut in half with a core saw. Some half sections sawn in quarters. ½ core used in
testwork.
If non-core, whether riffled, tube sampled, rotary split, etc. and whether
_sampled wet or dry. _
Not applicable as samples used in the reported testwork were DD core.
For all sample types, the nature, quality and appropriateness of the
sample preparation technique.
Whole continuous lengths of DD ½ core samples collected, composited and used in testwork.
These were collected to represent the composite intervals of both the High Grade and Low
Grade Zones.
Quality control procedures adopted for all sub-sampling stages to
maximise representivity of samples.
Subsampling is performed during the preparation stage according to the metallurgical
laboratories’internal protocol.
Measures taken to ensure that the sampling is representative of the in
situ material collected, including for instance results for field
duplicate/second-half sampling.
Use of DD core in metallurgical testwork gives a continuous insitu sample. PQ ensures high
recovery rates. DD core twinned previous RC drill holes. Whole sample interval used in
testwork.
Whether sample sizes are appropriate to the grain size of the material
being sampled.
Sample sizes are considered 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.
TSW Analytical Testwork
Testwork includes chemical precipitation of intermediate aluminium compounds from sulphuric
acid leachate solutions, solid liquid separations, purification steps involving recrystallisation and
ion exchange methods, and calcination. Assays are conducted on leach solutions and solid
residues, mother liquors and precipitates, eluates, precipitates and residue liquors.
TSW Analytical is a well-established analytical service provider that has developed a reputation
for producing accurate analyses for complex samples. The company’s expertise has assisted with
the development of hydrometallurgical flow-sheets for multi-element ore concentrates.
The titaniferous vanadiferous magnetite concentrate and leach residues have been assayed using
ICP-AES and ICP-MS. Solid samples were fused in a lithium borate flux, the resultant glass bead
was dissolved in hydrochloric acid and suitably diluted for either ICP-MS or ICP-AES analysis.
Loss on Ignition (LOI) at 1000OC was performed for completeness of the analytical data and to
give a better indication of the total analytical percentage approximation to 100%.
Soluble solid samples (such as intermediate aluminium compounds and recrystallised solids) were
digested in nitric acid and the digestate was suitably diluted for ICP-AES or ICP-MS analysis.
The liquor samples (such as leach solutions, wash liquors, mother liquors, and eluates) have been
analysed using ICP-AES and ICP-MS. The samples were diluted suitably for the appropriate ICP
based analysis. Dilutions are used to bring the analyte concentration into the optimum analytical
range of the ICP instrument used and to reduce matrix interference complications during
quantification.

==> picture [842 x 92] intentionally omitted <==

Precipitation efficiency has been determined using the mass of the total analyte in the leach
residue divided by the mass of the total analyte in the initial leach solution used. The resulting
fraction is multiplied by 100 to give percent precipitation efficiency.
Similarly the recovery of soluble solid precipitates has been determined using the mass of
analyte in the precipitate divided by the mass of the total analyte in the pregnant liquor from
which it was derived. The resultant fraction is multiplied by 100 to give the percent recovery.
TSW Analytical uses in-house standards and Certified Reference Materials (CRMs) to ensure
data are “Fit-For-Purpose”.
Nagrom Testwork
All solid samples have been analysed via XRF. The prepared sample is fused in a lithium borate
flux with a lithium nitrate additive. The resultant glass bead is analysed by XRF. Loss on Ignition
(LOI) is also conducted to allow for the determination of oxide totals.
MicroAnalysis Australia has analyses the 4N HPA by XRD methods to determine the alumina
phase.
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.
No geophysical data was collected.
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.
TSW Analytical
TSW reports concentrations as micrograms per gram (μg/g) in the solid (unless otherwise
stated). Instrumental response is measured against AccuTrace High Purity multi-element
standards (Choice Analytical) to achieve quantitation. Data are subjected to in-house QA and
QC procedures where an independent analyst recalculates instrumental output and compares
the newly generated data set with the original. Lack of equivalence between the two data sets
triggers an internal review and if necessary re-analysis of the entire data set. Under these
circumstances a third independent analyst will assess all generated data prior to sign off. Initial
equivalence between the two data sets, generated by the analyst and reviewer, will clear data for
remittance to the customer. All reports are reviewed by an independent analyst prior to
submission to the customer and where necessary relevant changes, such as wording that may
give rise to possible ambiguity of interpretation, will be modified prior to the final report being
sent to the customer.
Nagrom is certified to a minimum of ISO 9001:2008.
MicroAnalysis Australia is a commercial materials characterisation consulting laboratory with
comprehensive analytical and chemical science techniques

Verification of
sampling and
assaying
The verification of significant intersections by either independent or
alternative company personnel.
Significant intersections have been verified by alternative company personnel.
The use of twinned holes. All metallurgical DD core holes twinned previous RC holes. SDH11-12 has been twinned by
SDH11-13 and SDH11-14, SDH11-09 has been twinned by SDH11-10 and SDH11-11, and
SDH11-06 has been twinned by SDH11-07 and SDH11-08 (see Figure 2 and Table 1)
Documentation of primary data, data entry procedures, data verification,
data storage (physical and electronic) protocols.
Templates have been set up to facilitate geological logging. Prior to the import into the central
database, logging data is validated for conformity and overall systematic compliance by the
geologist. Assay results are received from the laboratory in digital format. Assays, survey data
and geological logs incorporated into a database.
Discuss any adjustment to assay data. No adjustments or calibrations will be made to any primary assay data collected for the purpose
of reporting assay grades and mineralised intervals.
Location of
data points
Accuracy and quality of surveys used to locate drill holes (collar and
down-hole surveys), trenches, mine workings and other locations used
in Mineral Resource estimation.
Almost 90% of the collars used in the resource estimate have been surveyed using a differential
global positioning system (DGPS) instrument, with the remaining surveyed using a hand-held
GPS. Downhole deviations have been measured by downhole survey instruments on 3 holes
only using a Globaltech Pathfinder digital downhole camera. All but four holes are vertical. All
metallurgical holes are vertical. The vertical and shallow nature of the drilling means that the
absence of downhole surveys is not considered a material risk.
Specification of the grid system used. The adopted grid system is GDA 94 Zone 52.
Quality and adequacy of topographic control. A topographic file provided by KRR was calibrated for use in the Mineral Resource estimate using
DGPS and GPS collar data. The Competent Person considers that the topography file is accurate
giventhe use of DGPS dataintheMineral Resource area.
Data spacing
and
distribution
Data spacing for reporting of Exploration Results. RC drill spacing is mostly 250 m by 250 m at the Central deposit, closing down to 100 m by 100
m in the western area (see Figure 1).
Metallurgical DD core holes are spaced about 500 m apart (see Figure 1).
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.
The Competent Person believes the mineralised domains have sufficient geological and grade
continuity to support the classification applied to the Mineral Resources given the current drill
pattern.
Whether sample compositing has been applied. Metallurgical samples were composited to represent the High Grade and Low Grade Zones
within the magnetite gabbro and within the resource envelope. This was considered
appropriate given the metallurgical testwork was designed to test the lower and high grade
zones of the mineralisation and it provided for a bulk sample suitable for the testwork.
Orientation of
data in relation
to geological
structure
Whether the orientation of sampling achieves unbiased sampling of
possible structures and the extent to which this is known, considering
the deposit type.
All metallurgical DD core holes are vertical. This allows the holes to intersect the mineralisation
at a high-angle as the magnetite gabbro has a very shallow dip to the east.
If the relationship between the drilling orientation and the orientation of
key mineralised structures is considered to have introduced a sampling
bias, this should be assessed and reported if material.
The relationship between the drilling orientation and the orientation of key mineralised
structures is not considered to have introduced a sampling bias.

Sample
security
Audits or
Reviews
The measures taken to ensure sample security. Chain of Custody is managed by the Company until samples pass to a duly certified
metallurgical laboratory for subsampling, assaying, beneficiation and hydrometallurgical test
work. The DD core samples are stored on secure sites and delivered to the metallurgical
laboratory by the Company or a competent agent. The chain of custody passes upon delivery
of the samples to the metallurgical laboratory.
The results of ay audits or reviews of sampling techniques and data. No external audits have been completed.

SECTION 2 : REPORTING OF EXPLORATION RESULTS

Criteria JORC Code explanation Commentary
Mineral
tenement and
land tenure
status
Type, reference name/number, location and ownership including
agreements or material issues with third parties such as joint ventures,
partnerships, overriding royalties, native title interests, historical sites,
wilderness or national park and environmental settings.
The security of the tenure held at the time of reporting along with any
known impediments to obtaining a licence to operate in the area.
The Speewah Project comprises 9 Exploration Licences, three Mining Leases and two
Miscellaneous Licences. Details are listed in Table 1 Schedule of Tenements held at 31 March
2020 reported previously in the March 2020 Quarterly Report. The Speewah testwork reported
in this announcement are from samples collected entirely within E80/2863. The tenements are
100% owned by Speewah Mining Pty Ltd (a wholly owned subsidiary of King River Resources
Limited), located over the Speewah Dome, 100km SW of Kununurra in the East Kimberley. The
tenements are in good standing and no known impediments exist. No Native Title Claim covers
the areas sampled and drilled. The northern part of the tenements (but not E80/2863) is in the
KimberleyHeritage Area.
Exploration
done by other
parties
Acknowledgment and appraisal of exploration by other parties. No exploration completed by other parties is relevant for the metallurgical testwork reported
herein.
Geology Deposit type, geological setting and style of mineralisation. The ferrovanadium titanium (Ti-V-Fe) deposits represent part of a large layered intrusion (the
Hart Dolerite), which was intruded c1790 Ma into the Palaeo-Proterozoic sediments and minor
volcanics of the 1814 Ma Speewah Group in the East Kimberley Region of Western Australia.
The deposits occur within the Speewah Dome, which is an elongated antiform trending N-S. The
dome is about 30 km long and attains a maximum width of about 15 km. The Hart Dolerite sill
forms the core of the dome.
Since the deposit discovery in 2006, at least two distinct types of felsic granophyres and three
mafic gabbros have been identified in the Hart Dolerite as follows:

K felsic granophyre (youngest)

Mafic granophyre

Pegmatoidal gabbro

Magnetite gabbro (host unit)

Felsic gabbro (oldest).
The vanadium-titanium mineralisation is hosted within a magnetite bearing gabbro unit of the
Hart Dolerite, outcropping in places and forming a generally flat dipping body that extends over
several kilometres of strike and width. The layered sill is up to 400m thick containing the
magnetite gabbro unit which is up to 80m thick.

==> picture [842 x 92] intentionally omitted <==

Given the mode of formation, mineralisation displays excellent geological and grade continuity
which was considered when classifying the Mineral Resource estimate.
Exposure is limited and fresh rock either outcrops or is at a shallow depth of a few metres.
Ti-V-Fe mineralisation occurs as disseminations of vanadiferous titano-magnetite and ilmenite.
Within the tenements the vanadium deposits have been divided into three deposits – Central,
Buckman and Red Hill. The test work reported in this announcement was sampled from the
Central vanadium deposit (Figure 1).
High purity alumina (HPA) is sourced from samples from the same magnetite gabbro unit within
the Central deposit that hosts the Ti-V-Fe deposit.
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
o hole length.
o 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.
New exploration results are not being reported.
Locations of diamond (DD) core holes, including metallurgical core holes used in this
announcement, are shown on Figure 2 and Table 1.
Data
aggregation
methods
In reporting Exploration Results, weighting averaging techniques,
maximum and/or minimum grade truncations (e.g. cutting of high
grades) and cut-off grades are usually Material and should be stated.
Exploration results are not being reported.
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 indetail.
Continuous lengths of ½ core composited for metallurgical samples from the Low Grade and
High Grade Zones.
The assumptions used for any reporting of metal equivalent values
should be clearly stated.
No metal equivalent values are used for reporting.
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 (e.g. ‘down hole length, true width not
known’).
Due to the very shallow dip of the mineralisation, the vertical metallurgical DD core holes
represent almost the true width of the mineralisation.
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 of drill
hole collar locations and appropriate sectional views.
Figure 2 shows the location of diamond core holes within the Central Vanadium deposit referred
to in this announcement.

Balanced
reporting
Where comprehensive reporting of all Exploration Results is not
practicable, representative reporting of both low and high grades and/or
widths should be practiced to avoid misleading reporting of Exploration
Results.
