Australian gold and nickel company, Rox Resources Limited (“Rox” or “the Company”) (ASX: RXL), in conjunction with its joint venture partner Venus Metals Corporation Limited (ASX: VMC) is pleased to report that extensional drilling at Youanmi continues to show that the project has significant upside.
Drilling at the Youanmi Gold Project near Mt Magnet, WA, in the OYG JV area (Rox 70% and Manager, VMC 30%) continues with an RC drilling and Diamond drill rigs operating (Figure 1). These are to be joined by an additional Diamond drilling rig shortly.
The next phase of drilling will involve more than 2,000m of diamond coring (in addition to RC pre-collars) testing depth extensions to high-grade ore shoots down plunge at Junction and Link (Figure 2). Additionally, step out drilling will test Rox’s exploration model with the aim of identifying recurring NW-plunging ore shoots within SW-plunging mineralised envelopes (Figures 3 and 4).
At the time of writing assay results are pending for 14 RC holes and 2 diamond holes drilled at the Link, Junction and Grace Targets.
Managing Director Alex Passmore commented: “The activity levels at Youanmi have continually ramped up through the year with the Company’s exploration model delivering exceptional results at Junction. We look forward to receiving results of the diamond drilling currently underway. The Company’s drilling results and re-interpretation work that has been undertaken since acquiring its interest in the Youanmi Gold Project have been incorporated into a new mineral resource estimate which is in the final stages of validation and which we look forward to releasing in the short term.”

Figure 1 Diamond and RC Rigs Operating at Youanmi Targeting Junction Mineralised Zone
Junction Target Area
Major accumulations of gold are found at the Youanmi Gold Project at the intersection zones between NorthSouth trending conjugate structures and the North-West trending Mine Shear. As a result, the Company has developed the Junction Target Area which is the interpreted convergence zone, at depth, between the historically mined Main Lode and the Grace Lode (Figure 3 and Figure 5).
The Grace Target is a strongly mineralised North-South trending conjugate structure that splays from the NorthWest trending Mine Shear. Current drilling is targeting where the Grace structure and Mine Shear converge at the Granite/Greenstone contact, a major rheological contrast boundary and highly favourable location for highgrade ore formation.
The Junction target area and Youanmi Underground Mine (Figure 3) are separated by the late-stage post mineralisation East-West striking Main Pit Fault that offsets the ore zones by ~30 metres. North of the Main Pit Fault, within the Mine Mineralised Envelope, the Youanmi underground development extends to a depth of 600 metres and known high-grade resources continue to ~950m below surface. The Junction area is immediately south of the Main Pit Fault within the Pollard Mineralised Envelope (Figure 3). Rox believes the Pollard mineralised envelope will continue to similar depths seen in the Mine Mineralised Envelope and has strong potential to host recurring North-West plunging ore shoots similar to the known mineralised envelopes at the Youanmi mine.
Rox is undertaking step out drilling to test this exploration model with the aim of adding to resource inventory which if successful should have a materially positive impact on ounces per vertical metre inventory.

ROX RESOURCES LIMITED 2 Level 2, 87 Colin Street, West Perth WA 6005 +61 8 9226 0044
The potential of the Junction target is demonstrated by recent drilling returning high-grade drill intercepts such as (ASX: 23 April 2021):
RXRC380: 4m @ 17.5g/t Au from 259m;
RXRC376: 4m @ 6.1g/t Au from 170m;
RXRC378: 3m @ 8g/t Au from 194m; and
RXRC379: 3m @ 7.1g/t Au from 243m at end of hole (Figure 3).
Link Target Area
The Link target area is situated within the Northern Mineralised Envelope that hosts the high-grade United North, Kathleen and Rebel-Kurrajong open pits and Hill End underground mine. At Link, a strongly mineralised NorthSouth trending conjugate structure intersects the NW trending Mine Shear and forms multiple north plunging high-grade ore shoots (Figure 4)
Drilling is targeting directly down plunge of the high-grade open pits and Hill End mine. There is strong potential for significant depth extensions to the known high-grade ore shoots.
The Company recently received promising results from RC drilling conducted at the Katheen Pit (Figure 6) and Hill End prospects during March 2021 (note: these assays were just received as the Company was trialling a different laboratory which as it transpired was slower than the regular service provider). Highlights are as follows:
RXRC372: 3m @ 6.4g/t Au from 183m (Kathleen);
RXRC374: 4m @ 5.2g/t Au from 104m (Kathleen) and 3m @ 2.8g/t Au from 126m;
RXRC382: 1m @ 6.3g/t Au from 229m; and
RXRC383: 3m @ 2.4g/t Au from 209m
These results will be followed up in due course with the focus currently on the high priority Junction target zone.
Forward plan
The current diamond and RC drilling program will target the Junction and Link areas, which continue to show strong potential to enhance and grow near mine gold resource inventory. The economic prospects of the Youanmi resource are considered strong being close to existing underground development.
The Company will continue to update the market on further results of ongoing drilling programs as they come to hand.

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 45% - 50%)
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.

JORC Table 1 - Section 1 Data and Sampling Techniques
| 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. 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 -650towards 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 picked up by differential GPS. 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 a cone splitter. Samples were sent to Intertek MinAnalytical in Perth, crushed to nominal <3mm, and 500g linear split into photon assay jars for Photon Gold analysis (PAAU2). |
|
| 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 150m to 280m for RC. |
| 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 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 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 RC chips recorded lithology, mineralogy, mineralisation, weathering, colour, and other sample features. RC chips are stored in plastic RC chip trays. |
|
| The total length and percentage of the relevant intersections logged All holes were logged in full. |
13
| Criteria | JORC Code explanation Commentary |
|---|---|
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. N/A |
| If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. RC samples were collected on the drill rig using a cone splitter. If any mineralised samples were collected wet these were noted in the drill logs and database. |
|
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. The sample preparation followed industry best practice. Photon samples were dried, crushed to nominal minus 3mm, and c. 500g linear split into photon assay jars for 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 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. The analytical technique involved Photon assay method on 500g sub-sample. |
| 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 or portable analysis tools were used to determine assay values stored in the database. |
|
| 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 samples as well as internal laboratory standards. All of these data are reported to the Company and analysed for consistency and any discrepancies. |
|
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. Senior personnel from the Company have visually inspected mineralisation within significant intersections. |
| The use of twinned holes. Twin drilling by Rox in shallower areas has verified the drill results of previous explorers. |
|
| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Primary data was collected using a standard set of Excel templates on Toughbook laptop computers in the field. These data are transferred to Geobase Pty Ltd for data verification and loading into the database. |
14
| Criteria | JORC Code explanation Commentary |
|---|---|
| Discuss any adjustment to assay data. No adjustments or calibrations have been made to any assay data. |
|
| Location of data points |
Accuracy and quality of surveys used to locate drillholes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Drill hole locations have been established using a field GPS unit. |
| Specification of the grid system used. The grid system is MGA_GDA94, zone 50 for easting, northing and RL. |
|
| Quality and adequacy of topographic control. The topography of the mined open pits is well defined by historic monthly survey pickups |
|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. RC drill hole spacing varies 40-200 metres between drill sections, with some areas at 40 metre drill section spacing. Down dip step-out distance varies 40-100 metres. |
| 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. Data spacing and distribution are sufficient to establish the degree of geological and grade continuity appropriate for JORC(2012) classifications applied. |
|
| Whether sample compositing has been applied. For RC samples, 1m samples through target zones were sent to the laboratory for analysis. The remainder of the hole was sampled using 4m composite samples. For 4m composite samples >0.2g/t Au, 1m samples were collected and sent to the laboratory for analysis. |
|
| 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 NNW-SSE and dips to the west at approximately -60 degrees. The drill orientation was 065 degrees -50 to -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 sample were delivered by a transport contractor the assay laboratory. The assay laboratory audits the samples on arrival and reports any discrepancies back to the Company. No such discrepancies occurred. |

| Geology | Deposit type, geological setting and style of mineralisation. 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. 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 Grace and the Plant Zone Prospects. Gold mineralization occurs as free particles within quartz-sericite altered granite shear zones. 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. |
| 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: • easting and northing of the drill hole collar • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar • dip and azimuth of the hole • down hole length and interception depth • hole length. Refer to drill results Table/s and the Notes attached thereto. |
| 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. All reported assay intervals have been length weighted. No top cuts have been applied. A lower cut-off of 0.5g/t Au was applied for RC. |
| 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. Mineralisation over 0.5g/t Au has been included in aggregation of intervals for RC. |
