West Australian gold exploration and development company, Rox Resources Limited (“Rox” or “the Company”) (ASX: RXL) is pleased to report high grade assay results from reverse circulation (RC) drilling at the Mt Fisher Gold Project (Rox 100%) and the Mt Eureka Project (Cullen Resources Joint Venture). Mt Fisher is an early-stage project within the Company’s project pipeline that includes the advanced stage Youanmi Gold Project (3.2 million ounces gold – ASX announcement 20 April, 2022).
The Mt Fisher-Mt Eureka Gold Project is located in the Northern Goldfields, approximately 500km northeast of Kalgoorlie (about 120km east of Wiluna) within the Mt Fisher greenstone belt. This belt is located 40km east of the prolific Yandal greenstone belt, host of significant gold deposits including Jundee, Bronzewing and Mt McClure (Figure 1).
Rox’s tenure covers a large area over the Mt Fisher greenstone belt (850km² in total, comprising: Rox 100% 500km², and Cullen Resources JV 350km²). Under the Cullen JV Rox is earning up to 75%, with Cullen Resources Limited holding the remaining 25%.
A 4,800m RC drill program and a 7,000m air core program were completed in December 2021 to test high priority gold targets that were generated from a detailed geological/geophysical data review. This current phase of drilling targeted numerous known gold occurrences including: the Mt Fisher Mine, the Dam/Damsel Gold Trend, Wagtail, Taipan, Southern-Galway and Eureka North-West (Figure 1).
Much of the past exploration in the belt has principally been surface geochemistry and shallow RAB drilling which highlighted strong gold anomalism although did not adequately test primary basement mineralisation. Rox’s RC drilling aimed to evaluate the continuity, grade and down dip extent of mineralisation beneath the weathered zone and into fresh basement rock.
Significantly, drilling intersected significant gold mineralisation at all target areas. The extensive nature and continuity of the gold mineralisation throughout the project area indicates the greenstone belt has strong potential for major new gold discoveries.
Managing Director Alex Passmore commented:
“The Mt Fisher greenstone belt is one of the least explored belts of the prolific Yilgarn craton, and these results shine a bright light on its potential gold endowment. This is an exciting development for Rox given our vast tenure position in the belt. Our technical team conducted a detailed review of all existing data to set the forward strategy which these results have served to validate.
These results highlight in particular the potential of the Damsel prospect which features large-scale gold anomalies and many of the geological features of major gold systems in the Yilgarn.
Damsel is located within a 1 km long gold anomaly (in regolith) defined by grades greater than 1 g/t Au. This area is part of a broader 7km long gold anomaly (>0.2g/t Au). Gold anomalism of this scale has the potential to reflect a large primary gold system. The results received at Damsel in this round of drilling provide a clear demonstration of the high gold grades and strong continuity at depth, and immediate follow up is planned.”

Mt Fisher Gold Project (Rox 100%)
Dam-Damsel Gold Trend
The Dam-Damsel Gold Trend is defined by strong gold and multi-element anomalism (Sb, As, Bi, Cu, and Zn) over 10km of strike within a well-defined structural corridor on the western limb of the Wonganoo Anticline. Mineralisation trends in a north-south orientation and is interpreted to be channelled along the bounding Dam and Dirks shear zones and particularly through an anastomosing network of linking structures between these major shears (Figure 2).
Historical drilling is mostly limited to shallow RAB with minimal testing of bedrock beneath the well-developed regolith anomalies along the Dam-Damsel-Dirk corridor.
Eleven RC holes were completed at the various prospects along the Dam-Damsel gold corridor. Results are discussed in detail below.
Damsel
The geology of the Damsel prospect comprises a package of north-south striking, strongly foliated tholeiitic to chloritic basalts intruded by felsic porphyries and dolerite/gabbro. The regolith is well developed over the area, with weathering up to 100m below surface. Primary gold mineralisation occurs in stacked parallel lenses that dip west and plunge moderately north. Mineralisation is associated with highly sheared silica-sericite-carbonate altered basalt and occurs with pyrite and chalcopyrite.
Historical drilling failed to test the extension of mineralisation to the north, with drilling ending above the mineralised shoot (missing the plunge). Seven RC holes were completed to test the down plunge extension and infill wider spacing drill sections.
The results reported in this announcement demonstrate strong continuity of high-grade mineralisation between drill sections. Mineralisation remains open down plunge to the north (Figure 3). High-grade results include:
-
MFRC081: 18m @ 6.99g/t Au from 69m, including 1 0m @ 10.27g/t Au from 74m
-
MFRC079: 2m @ 4.16g/t Au from 94m and 24m @ 1.22g/t Au from 112m, including 4m @ 3.67g/t Au from 120m
-
MFRC077: 13m @ 1.08g/t Au from 136m, including 2m @ 2.54g/t Au from 136m
Damsel mineralisation intersected by MFRC081 is open down dip and down plunge. The thickness of mineralisation and grade increases very substantially down dip from MFAC93 to MFRC021 to MFRC081 (Figure 4). Rox plans to test down dip of MFRC081 shortly.
The following figures include images related to exploration modelling of the Mt Fisher gold prospects. Indicative grade shell models (>0.2g/t Au, 1g/t Au) have been generated in Leapfrog software and are provided for reference only. The images of grade shell models are not an Exploration Target and do not contain nor indicate any estimate of potential size and grade ranges.

Dam
Anomalous regolith gold mineralisation is defined over 5 km in length at the Dam prospect (located within the Dam-Damsel Gold Trend). Gold mineralisation at Dam is associated with carbonate-silica-sericite-chlorite alteration of mafic lithologies and is characterised by an Au, Ag, As, Cu, Pb, Sb, W, Zn geochemical signature.
One RC hole was completed to test for south plunging primary mineralisation beneath strong regolith gold and antimony anomalism at Dam SE (Figure 5).
MFRC084 intersected 16m @ 2.58g/t Au from 164m, including 4m @ 3.49g/t Au from 164m and 4m @ 4.34g/t Au from 172m within strongly carbonate altered basalt (Figure 6). Follow up RC drilling is planned to define the extent of gold mineralisation along strike to the south.

Shiva
The Shiva Prospect is located 8km along strike to the south of the Dam-Damsel prospects. The gold in the regolith anomaly is defined over 1 km in length and overlies a complex zone of mafic extrusive and mafic intrusive lithologies. Primary gold mineralisation strikes north-northwest, dips west and plunges moderately south. Two RC holes were completed, significant results include: MFRC066: 1m @ 2.5g/t Au from 77m and 2m @ 1.55g/t Au from 91m, MFRC067: 4m @ 1.02g/t Au from 152m, 4m @ 1.18g/t Au from 160m.
Mt Fisher Mine
The historic Mt Fisher Mine is located on a neighbouring structural corridor approximately 8km NE of the DamDamsel gold trend. The Mt Fisher gold deposit is hosted within a sulphide facies chert, bounded by a strongly foliated chloritic ultramafic hanging wall and a basaltic footwall. The sequence strikes north-northeast and dips to the east at approximately 50°. Gold mineralisation occurs in association with massive and disseminated sulphides, mainly pyrrhotite, with lesser pyrite. Mineralisation plunges moderately southwards beneath the southern end of the existing open pit and is open at depth.
A ground electromagnetic (EM) survey by Rox in 2012 defined several conductive anomalies that are likely related to pyrrhotite associated gold mineralisation. The conductive anomaly is defined over 3km of strike length and appears to represent the down plunge extension of mineralisation at the Mt Fisher Mine.

Four RC holes were completed to test the down plunge extension of mineralisation. Additionally, one diamond drillhole was completed to test the centre of a conductive anomaly directly down plunge of the mine (Figure 7). The conductive anomalies to the south are yet to be tested by drilling.
High-grade results include:
-
MFRC065: 5m @ 6.31g/t Au from 222m within 9m @ 3.77g/t Au from 219m
-
MFDD002: 0.51m @ 4.52g/t Au from 319.45m, including 0.24m @ 8.64g/t Au from 319.45m
The results reported in this announcement demonstrate strong continuity of high-grade mineralisation up to 340m down plunge of the mine with mineralisation open along strike to the south and down dip to the east.
The sulphide assemblage through the mineralised zone consisted of semi massive pyrrhotite (up to 30%) and cross cutting quartz veining with pyrrhotite, pyrite and minor arsenopyrite; confirming that gold mineralisation is associated with massive and disseminated sulphides.
Downhole electromagnetic (DHEM) surveys will be completed on all drillholes to vector towards zones of potential thicker high-grade mineralisation.

Wagtail
The Wagtail prospect (also known as Moray Reef) is a quartz vein hosted gold reef system. Historic production from the deposit between 1949 and 1952 produced a reported 2,384 ounces at an average grade of 66 g/t Au. The reef strikes north, with a sub-vertical to steep easterly dip. High-grade mineralisation plunges moderately north. One RC hole was completed 80m down plunge to test for extensions of high-grade mineralisation (Figure 8). MFRC063 intersected 1m @ 4.66g/t Au from 127m, demonstrating geological continuity of the mineralised structure along strike and down dip. Follow up drilling is planned down dip of MFRC063 to test for zones of thicker mineralisation.

Southern and Galway
Mineralisation at the Southern and Galway prospects occurs within silicified shear zones developed on a northeast striking, northwest dipping contact between felsic volcaniclastic schist and ultramafic schist. (Figure 10).
Drilling was designed to test a shear zone beneath gold in regolith anomalies at Galway and to better understand the controls on gold mineralisation. A thick zone of high-grade gold mineralisation was intersected near-surface in MFRC075 (13m @ 6.81g/t Au from 45m, including 9m @ 8.89g/t Au from 47m). The intersection is highly encouraging as it indicates the potential for continuity of high-grade mineralisation within the interpreted northeast trending structure.
Follow up drilling is planned at depth and along strike to gain a better understanding of the geological controls on mineralisation in fresh rock.
At Southern, drilling was designed to test an interpreted NE plunge to mineralisation. However, the two holes at Southern (MFRC071 & MFRC074) were abandoned due to ground conditions and therefore failed to reach target depth. Both holes will be extended during the next drilling campaign.

Highlights from drilling at the Southern and Galway prospects include:
-
MFRC075: 13m @ 6.81g/t Au from 45m, including 9m @ 8.89g/t Au from 47m and 4m @ 2.59g/t Au from 67m at the Galway Prospect

Taipan
The Taipan shear zone is a large hydrothermal system in a complex structural setting (Figure 11). The mineralised system has a strike length of 700m and a true thickness of up to 150m and consists of sheared chlorite-quartz-biotite-carbonate schist containing moderately abundant fine disseminated pyrite. High grade gold mineralisation has been intercepted by historical drilling within the north portion of the deposit with intercepts of 20m @ 2.28g/t Au from 100m, including 2m @ 9.85g/t Au from 102m in MERC022 and 1m @ 17.4g/t Au in MEAC03 (RXL ASX Release 26 October 2021). Three RC holes were completed by Rox at Taipan in this round of drilling. These holes intercepted low grade mineralisation, however significant widths of up to 150m of highly sheared carbonate altered basalt with abundant quartz veining and minor pyrite were intercepted (Figure 12). Follow up RC drilling is planned along strike to the south to test for a primary source structure hosting higher grade mineralisation.
Highlights from this round of drilling include:
-
MFRC068: 1m @ 0.71g/t Au from 162m, 1m @ 1.14g/t Au from 172m, 1m @ 1.5g/t Au from 180m, 1m @ 0.7g/t Au from 185m, 1m @ 0.69g/t Au from 191m, 5m @ 0.69g/t Au from 194m and 2m @ 1.43g/t Au from 210m

Mt Eureka Northwest
Gold mineralisation is related to quartz veining and shearing in mafics associated with the granite-greenstone contact. Primary gold mineralisation strikes north-northeast, dips east and plunges moderately south. Two RC holes were completed to test the down plunge extension of mineralisation along the granite-greenstone contact. Significant results include: MFRC072: 4m @ 0.87g/t Au from 120m, MFRC073: 4m @ 0.58g/t Au from 4m, 3m @ 1.57g/t Au from 24m including 1m @ 3.35g/t Au from 25m and 1m @ 2.17g/t Au from 32m. Results indicate an extension of the mineralised structure to the south (albeit with only moderate grades/widths).

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 -2700or 900(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 was NQ2 size, sampled on geological intervals, with a minimum of 0.2 m up to a maximum of 1.2 m. 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 120m to 252m for RC and 313m 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. |

JORC Table 1 - Section 1 Data and Sampling Techniques
| 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. No holes have been twinned by Rox at this stage. |
|
| 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 51 for easting, northing and RL. |
|
| Quality and adequacy of topographic control. The topography of the mined open pit 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 40-100 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. RC and diamond 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. |
| Audits or reviews |
The results of any audits or reviews of sampling techniques and data. No audits have yet been completed. |

| Work conducted included aeromagnetic surveys, ground | ||
| magnetic surveys, regional mapping, rock chip sampling, soil | ||
| geochemistry (including BLEG and stream sediment | ||
| sampling) and rotary air blast (RAB) drilling. | ||
| The Mt Fisher deposit was first discovered in 1936 and | ||
| mining between 1937 and 1949 produced approximately | ||
| 4,500 tonnes of ore at 28 g/t gold (Powell, 1990). In 1980, a | ||
| small deposit was defined by percussion drilling around the | ||
| historical workings. Further drilling from 1984 to 1986 defined | ||
| a larger deposit to the south of the old workings with | ||
| Sundowner acquiring a 100% interest in the project in | ||
| January 1986. | ||
| Sundowner completed a historic estimate of 252,000 tonnes | ||

| Mineral Resources for the both the Dam and Moray Reef prospects. From 2004 to 2011, Avoca completed a total of 158 RAB/AC drill holes for 9,111 m and 64 shallow RC drill holes for 5,188 m. |
|
| Geology | Deposit type, geological setting and style of mineralisation. The geological setting is of Archean aged with common host rocks and structures related to mesothermal orogenic gold mineralisation as found throughout the Yilgarn Craton of Western Australia. |
| 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 with 1m of interval dilution allowed. See Table/s.. |
| 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. A lower cut-off of 0.5g/t Au was applied with 1m of interval dilution allowed. Higher grade intervals are reported at lower cut-off of 5g/t Au with 1m of interval dilution allowed. |
|
| 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. However reported intercepts will usually be more than true width. |
| 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. Indicative grade shell models (>0.2g/t Au, >1g/t Au) are included in figures within this announcement. These grade shell models have been generated in Leapfrog software. These grade shells are provided for reference only. The images of grade shell models are not an Exploration Target and do not contain nor indicate any estimate of potential size and grade ranges. |
