Australian gold and nickel company, Rox Resources Limited (“Rox” or “the Company”) (ASX: RXL), in conjunction with its joint venture partner Venus Metals Corporation (ASX: VMC) is pleased to announce that initial gravity and cyanide leach recovery test work has delivered high gold recoveries from the Grace discovery at Youanmi in the OYG JV area (Rox 70% and Manager, VMC 30%).

This metallurgical program tested both oxide and fresh RC samples from the Grace deposit as a sighter program to aid in the design of a more comprehensive testing regime. Compared to gold mineralisation mined historically at Youanmi, gold at Grace is hosted in low-suphide gold mineralisation within fractured, altered granite. As a result of 2020 drilling, granite-hosted gold has been intersected over a mineralised corridor extending 2.5km to the north of the mine area. The Grace deposit extends for +700m in the near mine area (figure 1).

Results were positive and confirmed excellent recoveries with total gold extraction of up to 99.8% using a combination of gravity and 24-hour cyanide leach bottle rolls. High gravity recoveries prior to cyanide leaching of up to 69% of total gold recovered were achieved through a Knelson Concentrator.

Managing Director Alex Passmore commented : I am pleased with these excellent initial metallurgical test work results from the Grace deposit. Particularly encouraging is the relatively high gravity recoverable gold from a coarse grind. Gold ores at Youanmi show a variety of metallurgical characteristics however what it is becoming evident that the granitehosted, low sulphide mineralisation such as that at Grace are free milling (i.e. therefore amenable to conventional CIL).

www.roxresources.com.au

Results are summarised as:

Oxide Gold Ore - RXRC268 (12m)

Excellent total gold extractions of 97.74% (130µm grind) and 98.73% (75µm grind) through a combination of gravity and 24-hour cyanide leach bottle rolls.

High gravity recoveries of 66.91% (130µm grind) and 68.91% (75µm grind) of total gold recovered through Knelson Concentrator prior to cyanide leaching.

Fresh Gold Ore - RXRC287 (153m)

Excellent total gold extractions of 93.52% (130µm grind) and 99.83% (75µm grind) through a combination of gravity and 24-hour cyanide leach bottle rolls.

High gravity recoveries of 67.06% (130µm grind) and 69.18% (75µm grind) of total gold recovered through a Knelson Concentrator prior to cyanide leaching.

Results of the preliminary program indicate that the Grace deposit will be amenable to a conventional gravity and cyanide leach processing circuit.

Methodology

All test work was conducted by ALS Metallurgy Pty Ltd in Perth.

Samples for metallurgical test work were collected from coarse rejects of two RC samples previously submitted for fire assay as part of recent exploration activities. The samples selected are considered as typical examples of the mineralisation at Grace.

The coarse rejects (~30kg) were crushed to <3.35mm and homogenised / split via a rotary sample divider to obtain two 1kg composites from both oxide and fresh samples. The composites were subsequently ground to a P80: 130µm and a P80: 75µm and head assays completed for the total composite.

The composites were then put through a Knelson Concentrator and gravity gold recovered by intensive cyanidation of the Knelson concentrate. The Knelson Concentrator tails and intensive cyanidation residue were then subjected to a 24-hour bottle roll, using Perth tap water. The recovered gold in solution from the bottle roll was then added to the gravity recovered component to give total recovered gold for the sample. Residues were assayed by fire assay and the total gold recovery calculated.

For the Oxide Gold Ore Extraction Composite sample, the results of the two grind tests at P80: 130µm and P80: 75µm, indicated that this composite contains elevated levels of coarse gravity recoverable gold with 66.91% and 68.91% respectively. With cyanidation of the gravity tail, the overall gold recoveries were 97.74% and 98.73% respectively. The final residue gold grades were 0.54g/t and 0.32g/t Au respectively. For both tests the gold leach kinetics were fast with the bulk of the gold leaching in the first 2-4 hours. For both gravity tail leach tests the lime and sodium cyanide consumption rates were low with Perth tap water. For both P80: 130µm and P80: 75µm tests the calculated gold head grade from the gravity and leach test was 23.9g/t and 24.9g/t Au respectively, which are both lower than the initial duplicate gold head assays of 60.1 / 65.1g/t Au. This discrepancy is most likely due to the high levels of coarse “spotty” gold in this composite.

For the Fresh Gold Ore Extraction Composite sample, the results of the two grind tests at P80: 130µm and P80: 75µm, indicated that this composite also contains elevated levels of coarse gravity recoverable gold with 67.06% and 69.18% respectively. With the cyanidation of the gravity tail, the overall gold recoveries were 93.52% and 99.83% respectively. The final residue gold grades were 12.9g/t and 0.24g/t Au respectively. The elevated residue gold grade for the P80: 130µm test may be due to a coarse piece of gold that was not picked up in the gravity concentrate and did not fully leach after the 24 hour leach duration. The gold leach kinetics were fast with the bulk of the gold leaching in the first 2-4 hours. Also for both gravity tail leach tests the lime consumption and sodium cyanide consumption rates were low with Perth tap water. For both P80: 130µm and P80: 75µm tests the calculated gold head grade from the gravity and leach test was 199g/t and 140g/t Au respectively, which are both higher than the initial duplicate gold head assays of 89.4 / 98.4g/t Au. This discrepancy is again most likely due to the high levels of coarse “spotty” gold in this composite.

The first pass results indicate that ore derived from Grace should be amenable to conventional gravity and cyanide processing and excellent recoveries should be achievable from an optimised process route.

Grace

Grace mineralisation is hosted within a west dipping zone of strong sericite altered granite, shear veins and quartz breccia-style veins within an overall NNW trending structural zone adjacent to the historically mined Youanmi Main Lode. The rocks in this area are significantly weathered (i.e. oxide zone) down to an average 50m depth below surface. There is a transitional zone from 50 to 80m on average and then fresh rock (i.e. containing primary mineralisation) below 80m.

The metallurgical samples were collected from two drill holes as noted in Table 4 below.

About Rox Resources

Rox Resources Limited is an emerging Australian minerals exploration company. The company has a number of key assets at various levels of development with exposure to gold, nickel, copper and platinum group elements (PGE’s). The 1.2Moz Youanmi Gold Project and the Fisher East Nickel Project (78kt Ni) being the most advanced projects with exploration ongoing at the Mt Fisher Gold Project and the Collurabbie Nickel-Copper-PGE Project.

Youanmi Gold Project (Youanmi Gold Mine 70%, Regional JV’s 50% earn-in)

The Youanmi Gold Mine is located 480 km to the northeast of Perth, Western Australia. The Youanmi Mining Centre has produced an estimated 667,000 oz of gold (at 5.47 g/t Au) since discovery in 1901 during three main periods: 1908 to 1921, 1937 to 1942, and 1987 to 1997.

The project is situated in the Youanmi Greenstone Belt, within the Southern Cross Province of the Archaean Yilgarn Craton in Western Australia. The structure of the Youanmi Project is dominated by the north-trending Youanmi Fault Zone. Most of the gold mineralisation seen at the project is hosted within north-northwest splays off the north-northeast trending Youanmi Fault.

Fisher East Nickel Project (100%)

The Fisher East nickel project is located in the North Eastern Goldfields region of Western Australia and hosts several nickel sulphide deposits. The total project area is ~350km2.

Discovery of, and drilling at the Camelwood, Cannonball and Musket nickel prospects has defined a JORC 2012 Mineral Resource (ASX:RXL 5 February 2016) of 4.2Mt grading 1.9% Ni reported at 1.0% Ni cut-off (Indicated Mineral Resource: 3.7Mt grading 1.9% Ni, Inferred Mineral Resource: 0.5Mt grading 1.5% Ni) comprising massive and disseminated nickel sulphide mineralisation, and containing 78,000 tonnes of nickel. Higher grade mineralisation is present in all deposits (refer to ASX announcement above) and is still open at depth beneath each deposit. Additional nickel sulphide deposits continue to be discovered (e.g. Sabre) and these will add to the resource base. Exploration is continuing to define further zones of potential nickel sulphide mineralisation.

Collurabbie Gold-Nickel Project (100%)

The Collurabbie project is located in the highly prospective North Eastern Goldfields region of Western Australia and is prospective for gold and nickel. The project area of ~123km2 hosts the Olympia nickel sulphide deposit and a number of other prospects for nickel sulphide mineralisation. A JORC 2012 Inferred Mineral Resource of 573,000t grading 1.63% Ni, 1.19% Cu, 0.082% Co, 1.49g/t Pd, 0.85g/t Pt has been defined at Olympia (ASX: RXL 18 August 2017). The style of nickel sulphide mineralisation is different to that at Fisher East, with a significant copper and PGE component at Collurabbie, and has been compared to the Raglan nickel deposits in Canada (>1Mt contained nickel). In addition, there is potential for gold mineralisation, with several strong drilling intersections including 2m @ 2.4g/t Au from the Naxos prospect.

Mt Fisher Gold Project (100%)

The Mt Fisher gold project is located in the North Eastern Goldfields region of Western Australia, adjacent to the Fisher East nickel project, and hosts several gold deposits. The total project area is ~220km2.

Drilling by Rox has defined numerous high-grade gold targets and a JORC 2012 Measured, Indicated and Inferred Mineral Resource (ASX:RXL 11 July 2018) of 1.0 million tonnes grading 2.7 g/t Au reported at a 0.8 g/t Au cut-off exists for 89,000 ounces of gold (Measured: 170,000 tonnes grading 4.1 g/t Au, Indicated: 220,000 tonnes grading 2.7 g/t Au, Inferred: 630,000 tonnes grading 2.3 g/t Au) aggregated over the Damsel, Moray Reef and Mt Fisher deposits.

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.
RC hole diameter was 5.5" (140 mm) reverse circulation
percussion (RC). Sampling of RC holes was undertaken by
collecting 1m cone split samples at intervals.
Drill holes were generally angled at -600towards grid
northeast (but see Table for individual hole dips and
azimuths) to intersect geology as close to perpendicular as
possible.
Include reference to measures taken to ensure sample
representivity and the appropriate calibration of any
measurement tools or systems used
Drillhole locations were surveyed with DGPS by a licensed
surveyor. Logging of drill samples included lithology,
weathering, texture, moisture and contamination (as
applicable). Sampling protocols and QAQC are as per
industry best practice procedures.
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
RC drillholes were sampled on 1m intervals using riffle or
cone splitter units.
Coarse reject (~30kg) from RC samples were sent to ALS
Metallurgy Pty Ltd in Perth, crushed to 3.35mm,
homogenise / split via rotary sample divider. 200g head
assay were conducted via 50g fire assay. 1kg samples were
subsequently ground to P80: 130µm and P80: 75µm.
The samples put through a Knelson Concentrator and
gravity gold recovered by intensive cyanidation with the
non-gravity recovered residue then being added to a 24-
hour bottle roll, using Perth tap water. Residues were
assayed by 50g fire assay.
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).
Drilling technique was Reverse Circulation (RC). The RC
hole diameter was 140mm face sampling hammer. Hole
depths reported range from 5m to 200m.
Drill sample
recovery
Method of recording and assessing core and chip
sample recoveries and results assessed
RC drill recoveries were high (>90%).
Measures taken to maximise sample recovery and
ensure representative nature of the samples
RC samples were visually checked for recovery, moisture
and contamination and notes made in the logs.
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.
There is no observable relationship between recovery and
grade, and therefore no sample bias.
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.
Detailed geological logs have been carried out on all RC drill
holes, but no geotechnical data have been recorded (or is
possible to be recorded due to the nature of the sample).
The geological data would be suitable for inclusion in a
Mineral Resource estimate.
Whether logging is qualitative or quantitative in nature.
Core (or costean, channel, etc) photography.
Logging of RC chips recorded lithology, mineralogy,
mineralisation, weathering, colour, and other sample
features. RC chips are stored in plastic RC chip trays.

The sample preparation followed industry best practice. Samples were dried, coarse crushing to ~10mm, followed by pulverisation of the entire sample in an LM5 or equivalent pulverising mill to a grind size of 85% passing 75 micron.

Metallurgical test work sampling by ALS was as follows: Cyanidation Time Leach Testwork. Groundsamples of each of the composite were submitted for cyanidation time leach testwork to determine gold recovery rates at a primary grind of P80 75 µ and P80 130 µ

The gravity gold recovery procedure is summarised as follows:

(1) 1.0 kg sub-samples were ground to the P80 75 µ and P80 130 µ and passed through a 3” Knelson KC-MD3 gravity concentrator, with the following specifications: • Feed rate ~650-700 g/min

• 1500 rpm

• 3.5 L/min fluidising water flow rate.

(2) The Knelson gravity concentrate was recovered and transferred to a 1-litre bottle and combined with Perth Tap water to produce 20% solids (w/w).

(3) The concentrate sample was leached for 24 hours with 0.8% NaOH, 2% Leachwll and 5.0% Cyanide.

(4) The solution was recovered and analysed for Gold.

For all sample types, the nature, quality and appropriateness of the sample preparation technique.

(5) The Gravity Concentrate leach residue (Knelson concentrate) was combined with the Knelson tail and submitted for further cyanide leach testwork.

Gravity Tailing Recovery Procedure (1) The intensive leach tails were combined with the Knelson tailings for further cyanidation.

(2) The gravity tailings were transferred into a 3-litre plastic leach bottle, fitted with a screw-on lid, along with a sufficient quantity of water to generate a slurry sample at 40% solids (w/w).

(3) The bottle was placed on a set of mechanically driven rolls to thoroughly agitate the slurry sample prior to measuring the natural pH and dissolved oxygen level of the pulp.

(4) A sufficient quantity of hydrated lime (60% CaO) was added to the pulp to target a pH of 10.0, which was checked after 5 more minutes of agitation, and if necessary more lime was added or until the buffer point was reached.

(5) A quantity of solid sodium cyanide was added to the pulp sample to establish an initial, nominal, cyanide solution strength of 0.10% (w/v).

(6) Intermediate 30 mL solution samples were removed after intervals of 2, 4, 8, and 24 hours had elapsed. These were utilised for gold analysis and solution cyanide strength determination via titration with silver nitrate. The solution

removed was replaced with an equivalent volume made up
to the required pH and cyanide concentration levels.
(7)
At each sampling interval more lime and sodium
cyanide were added if necessary to maintain values of
>9.5% and 0.050%, respectively.
(8)
At the termination of the leach test (48 hours) the
terminal pH, dissolvedoxygen and cyanide levels were
measured, and a solution sample was taken for gold and
other element analysis.
(9)
The leach residue was filtered, washed, dried and
weighed, and a sub-sample was submitted for gold
analysis.
Quality control procedures adopted for all sub-
sampling stages to maximise representivity of samples.
Field QC procedures involve the use of Certified Reference
Materials (CRM’s) as assay standards, along with
duplicates and blank samples. The insertion rate of these
was approximately 1:20.
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.
For RC drilling field duplicates were taken on a routine basis
at an approximate 1:20 ratio using the same sampling
techniques (i.e. cone splitter) and inserted into the sample
run.
Whether sample sizes are appropriate to the grain size
of the material being sampled.
The sample sizes are considered more than adequate to
ensure that there are no particle size effects relating to the
grain size of the mineralisation which lies in the percentage
range.
Quality of assay

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.
Internal laboratory control procedures involve duplicate
assaying of randomly selected assay pulps as well as
internal laboratory standards. All of these data are reported
to the Company and analysed for consistency and any
discrepancies.

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.
The mineralisation strikes generally north-south and dips to
the west at between -50 to -70 degrees. The drill orientation
was 065 degrees and -60 dip. Drilling is believed to be
generally perpendicular to strike.
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.
No sampling bias is believed to have been introduced.
Sample security The measures taken to ensure sample security.
Sample security is managed by the Company. After
preparation in the field samples are packed into polyweave
bags and despatched to the laboratory. For a large number
of samples these bags were transported by the Company
directly to the assay laboratory. In some cases the samples
were delivered by a transport contractor to the assay
laboratory. The assay laboratory audits the samples on
arrival and reports any discrepancies back to the Company.
No such discrepancies occurred.

Criteria JORC Code explanation Commentary
Geology The Youanmi Project straddles a 40km strike length of the
Youanmi Greenstone Belt, lying within the Southern Cross
Province of the Archaean Yilgarn Craton in Western
Australia. The greenstone belt is approximately 80km long
and 25km wide, and incorporates an arcuate, north-trending
major crustal structure termed the Youanmi Fault Zone. This
structure separates two discordant greenstone terrains, with
the stratigraphy to the west characterised by a series of
weakly deformed, layered mafic complexes (Windimurra,
Black Range, Youanmi and Barrambie) enveloped by
strongly deformed, north-northeast trending greenstones.
Gold mineralisation is developed semi-continuously in shear
zones over a strike length of 2,300m along the western
margin of the Youanmi granite.
The Youanmi gold lodes are invariably associated with a high
pyrite and arsenopyrite content and the primary ore is
partially to totally refractory.

geological
setting

and
style
of There are a series of major fault systems cutting through the
Youanmi trend mineralisation that have generated some
significant off-sets.
The Youanmi Deeps project area is subdivided into three
main areas or fault blocks by cross-cutting steep south-east
trending faults; and these are named Pollard, Main, and Hill
End from south to north respectively.
Granite hosted gold mineralisation occurs at several sites,
most notably the Grace Prospect. Grace mineralisation is
hosted within a W dipping zone of strong sericite altered
granite, shear veins and quartz breccia-style veins within an
overall NNW trending structural zone.
The Commonwealth-Connemarra mineralised trend is
centred 4km northwest of the Youanmi plant. The geology
comprises a sequence of folded mafic and felsic volcanic
rocks intercalated with BIF and intruded by granite along the
eastern margin. Gold mineralisation is developed over a
600m strike length, associated with a north trending and
steeply west dipping shear zone that traverses the northwest
trending succession.

Commentary
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.
High grade intervals internal to broader zones of
mineralisation are reported as included intervals. See
Table/s.
The assumptions used for any reporting of metal
equivalent values should be clearly stated.
No metal equivalent values have been used or reported.
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’).
No definite relationships between mineralisation widths and
intercept lengths are known from this drilling due to the highly
weathered nature of the material sampled.
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.
Refer to Figures and Table in the text.
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.
Representative reporting of both low and high grades and
widths is practiced.
Other
substantive
exploration data
Other exploration data, if meaningful and material,
should be reported including (but not limited to):
geological observations; geophysical survey results;
geochemical survey results; bulk samples – size and
method of treatment; metallurgical test results; bulk
density,
groundwater,
geotechnical
and
rock
characteristics; potential deleterious or contaminating
substances.
All meaningful and material information has been included in
the body of the announcement.
Further work The nature and scale of planned further work (e.g. tests
for lateral extensions or depth extensions or large-scale
step-out drilling).
Diagrams clearly highlighting the areas of possible
extensions, including the main geological interpretations
and future drilling areas, provided this information is not
commercially sensitive
Further work (RC and diamond drilling) is justified to locate
extensions to mineralisation both at depth and along strike.
