West Australian focused gold exploration and development 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 provide an update on drill results from the Youanmi Gold Project near Mt Magnet, WA, in the OYG JV area (Rox 70% and Manager, VMC 30%).
Results reported in this release are from a 40m x 40m spaced (i.e. grid) drill pattern at the Link Prospect that is designed to convert mineralisation in this zone to additional gold resource inventory at Youanmi. This drilling, which intersected Link mineralisation at depths between 170m and 260m below surface, demonstrates that mineralisation in this area shows good continuity and should readily convert to resource ounces.
Managing Director Alex Passmore commented: “We are pleased to report further high-grade results from the Link Prospect at Youanmi. These latest assays add to our confidence that mineralisation in this area is hanging together nicely and will deliver into an updated resource inventory in due course. Link mineralisation occurs from near surface to 370 metres below surface and is open at depth. Link plunges below the previously mined United
1
North open pit and is also in close proximity to underground workings at depth, yet was not discovered until our recent exploration programs.”
Resource Growth at Link Prospect
Drilling is focussed on further growing the recently updated resource inventory at Youanmi, which currently stands at 1.7Moz at 2.85g/t Au (ASX: RXL 23 June 2021). Both resource extension and inferred to indicated resource conversion drilling is being undertaken in the near mine area.
Significantly, the June 2021 resource upgrade did not include any results from 2021 drilling, which will be incorporated into the next resource upgrade that is currently expected in the first half of calendar year 2022, pending the timing of the completion of outstanding drill assays. This upgrade is expected to both increase the resource base, and improve the confidence category of existing resources.
The results reported in this announcement demonstrate continuity of high-grade mineralisation at Link prospect (Figure 1) which augurs well for increases to the overall mineral resource.
The results (Table1, Figure 1) include:
-
RXRC430: 3m @ 9.35g/t Au from 182m within 5m @ 6.33g/t Au from 180m
-
RXRC428: 2m @ 7.93g/t Au from 279m within 9m @ 3.02g/t Au from 272m
-
RXRC426: 2m @ 12.59g/t Au from 235m within 3m @ 8.61g/t Au from 235m
-
• RXRC406: 2m @ 7.81g/t Au from 234m within 7m @ 2.82g/t Au from 230m
These results define a zone of high-grade mineralisation more than 100m from the current resource within close proximity to both the base of historic open pits and underground development (Figure 1). Infill drilling in this zone is expected to add inventory to the Youanmi indicated resource category in an area with near term production potential.
Drilling to date at the Link Prospect has defined a zone of high-grade mineralisation more than 200m from the current resource envelope with extensive down-plunge continuity of high-grade ore zones.
Mineralisation at Link is open down plunge to the northwest and up dip to the southeast.
Results are pending for 18 RC and 14 diamond holes in addition to 22,000m of aircore drilling undertaken on regional prospects.

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. Diamond drill hole core size is NQ2 size diameter through the mineralisation. Sampling of diamond holes was by cut half core as described further below. 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. Diamond core is dominantly NQ2 size, sampled on geological intervals, with a minimum of 0.2 m up to a maximum of 1.2 m. HQ and NQ2 holes were cut in half, with one half sent to the lab and one half retained. Samples were sent to Intertek Genalysis in Perth, crushed to 10mm, dried and pulverised (total prep) in LM5 units (Some samples > 3kg were split) to produce a sub-sample. RC and diamond pulps were analysed by 50g Fire Assay with ICP-OES (Intertek code FA50/OE). |
|
| 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) and diamond core (DD). The RC hole diameter was 140mm face sampling hammer. Hole depths reported range from 200m to 300m for RC and 350m to 700m for diamond. |
| 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. |
9
| Criteria | JORC Code explanation Commentary |
|---|---|
| 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, but no geotechnical data have been recorded (or is possible to be recorded due to the nature of the sample). Detailed geological and geotechnical logs were carried out on all diamond drill holes for recovery, RQD, structures etc. which included structure type, dip, dip direction, alpha angle, beta angle, texture, shape, roughness, fill material, and this data is stored in the database. 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 diamond core and 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. |
|
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. Drill core was cut in half on site using a core saw. All samples were collected from the same side of the core, preserving the orientation mark in the kept core half. |
| 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. Fire Assay 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. |
|
| 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. No diamond core field duplicates were taken. |
|
| 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 Fire Assay 50g. |
| 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 assay pulps 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. | Two twin RC holes have been completed at the Grace Prospect and confirm reliability of previous results. |
|
| 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. |
|
| 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 and diamond 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 20-100 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. | No sample compositing has occurred for diamond core drilling. Sample intervals are based on geological boundaries with even one metre samples between. 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 -50 degrees. The drill orientation was 065 and 245 degrees and -60 to -90 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. |

| 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 and diamond core. |
| 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 and diamond core. |
