Overall gold recoveries of up to 96% via Locked Cycle Flotation Testwork (91% staged recovery to concentrate) then float tails CIL (5% staged recovery).
Flotation produces high concentrate grades of +50g/t gold with a low arsenic grade and mass pull, confirming that a concentrate sales pathway provides a low CAPEX, simplified flowsheet.
BIOX[®] test-work delivers very high gold recoveries of 95.6% from concentrate, at low oxidation rates.
Engineering works well advanced to provide CAPEX and OPEX estimates for three potential processing options (BIOX[®] , Albion[®] and Concentrate sales).
Geo-metallurgical work currently underway to determine the varying mineralogy to refine the optimal flowsheet.
Youanmi Pre-Feasibility Study (PFS) scheduled to be completed by end-July 2024.

West Australian gold exploration and development company Rox Resources Limited (“Rox” or “the Company”) ( ASX: RXL ) is pleased to report high gold recoveries from multiple flowsheets based on recent metallurgical test work programs on its 100%-owned Youanmi Gold Project in Western Australia.

The metallurgical test work program has focused on the fresh sulphide portion of the Mineral Resource, which is the focus of the PreFeasibility Study (PFS) currently nearing completion.

Rox Resources Managing Director, Robert Ryan, commented:

“The results from the current metallurgical test program build on the swathes of previous metallurgical test work and historical processing data at Youanmi. The results highlight strong gold recoveries to a concentrate and exceptional recoveries from low oxidation rates in both BIOX[®] and Albion[®] technologies.

“Engineering works are well advanced with detailed estimates for OPEX and CAPEX due by the end of June, which will allow for PFS completion by the end of July.”

Flotation Testwork

Rox provided ALS Metallurgy (ALS) with a composite sample of 67.3kg of selected quartered NQ sized core from a recent drilling campaign in the Link Resource area. All selected core was representative of the PFS mine plan at Link. This composite sample complemented previous flotation testwork conducted on other areas in the mine plan, being Main and Pollard.

Locked Cycle Testwork (LCT) was conducted by ALS in Perth, under the supervision of JT Metallurgical Services (JT), who acted as the lead manager for all these testwork campaigns on behalf of Rox.

Locked Cycle Testwork aims to simulate the continual nature of the flotation circuits, providing a more accurate representation of how the circuit would perform at full scale compared to batch testwork. Float tests were conducted at a feed size of P80 75µm. Float and leach testwork was conducted in site raw water.

Two flowsheets were assessed as part of the PFS testwork, including:

Flowsheet #1 – Rougher/Scavenger, Cleaner, Re-cleaner: Flotation feed to rougher/scavenger, rougher/scavenger concentrate cleaned, with the cleaner tail returned to the flotation feed. Cleaner concentrate reports to the re-cleaner with the re-cleaner tail reporting to the cleaner feed. Re-cleaner concentrate reports to final concentrate; and

Flowsheet #2 – Rougher/Scavenger, Cleaner, Re-cleaner with Concentrate Regrind: Flotation feed to rougher/scavenger, rougher/scavenger concentrate cleaned, with the cleaner tail returned to the flotation feed. Cleaner concentrate is ground to P100 53μm prior to reporting to the re-cleaner. The re-cleaner tail reports to the cleaner feed. Re-cleaner concentrate reports to final concentrate.

A total of six cycles were completed on each of the flowsheets.

The results of LCT 1 and LCT 2 are shown in Table 1 below. This shows that the finer regrind of LCT 2 achieved a higher overall gold, sulphide and arsenic grade, and a lower overall mass pull compared to LC1 (11.6% to 13.5%).

Cycle 6 rougher tails from both locked cycle tests were representatively sampled and subjected to a cyanidation leach, reflecting a flowsheet consisting of flotation followed by a CIL on the flotation tail, provided in Table 2 below.

LC2 Cycle 6 Rougher Tail	75 μm	0.86	0.87	0.32	54.42	95.70

Average lime and cyanide consumptions are considered low (0.83kg/t and 0.16kg/t).

The flotation tail leach achieved an average leach extraction of 55.19% at 48 hours. Factoring in the flotation concentrate, the sample achieved a total extraction (either leached or collected as a flotation concentrate) of 96.27% and 95.70% for LC1 and LC2 respectively.

The following is noted from the flotation concentrate assay results:

Low arsenic concentrations. Concentrations are below the common smelter-imposed penalty threshold.
Low total and organic carbon content;
Both samples show low levels of common deleterious elements such as bismuth, tellurium, lead, cadmium and mercury – which is in line with historical results;
Variable silicate concentrations between tests, significant reduction in silicate concentration in LC2 indicates that the regrind was effective in reducing non-sulphide gangue reporting to concentrate; and
3.00% silicate in LC2 is indicative of good froth drainage and low concentrations of non-sulphide gangue minerals such as clays and other hydrophobic minerals. This is indicative that additional cleaning stages are unlikely to significantly improve the concentrate grade, hence are not required.

BIOX[®] Test work

==> picture [71 x 67] intentionally omitted <==

Metso was engaged to assess the Youanmi ore using their proprietary BIOX[®] bacterial oxidation technology. Metso has previously tested samples from Youanmi in both 1990 and 1992.

Approximately 4.1kg (dry weight equivalent) of the 2022 ROM Composite Flotation Concentrate was sent over to SGS Johannesburg for BIOX[®] amenability test-work. This material was selected so that a direct comparison to previous Albion[®] test-work could be conducted. A total of seven BIOX[®] Batch Amenability Tests (BATs) were completed on the provided concentrate sample. The tests assessed the degree of sulphide oxidation across different bacterial oxidation incubation periods, namely:

BAT 1 – 12 days
BAT 2 – 15 days
BAT 3 – 7 days
BAT 4 – 16 days
BAT 5 – 13 days
• BAT 6 – 9 days
BAT 7 – 10 days

All BAT tests were inoculated with an identical quantity of Youanmi adapted culture. All other tests parameters including nutrient additions, initial and total acid additions and temperature were all kept constant across all tests.

The results of the tests are shown in Table 3 below:

Table 3: BIOX[®] Oxidation Results

		Sulhide	Arsenic	Iron
BAT Test	Period (Days)	p Oxidation (%)	Solubilisation (%)	Solubilisation (%)
BAT 3	7	37.4	98.9	35.3
BAT 6	9	92.8	99.7	78.5
BAT 7	10	97.8	99.7	83.2

BAT 2	15	98.6	99.7	84.7
BAT 4	16	99.1	99.7	85.7

On completion, each BAT test was filtered and the residue washed to remove any residual acid and dried at 50°C. A representative sub-sample was taken for cyanidation test-work. A cyanidation test was also completed on an un-oxidised sample for comparison. Results of the cyanidation test-work are presented in Table 4 below:

BAT 7	98	6.1	3.2	29.20	1.14	320	96.4	91

The tests show that the bacterial oxidation of the sample was effective in increasing the cyanidation leach recovery compared to the unoxidised sample by more than 35.8%. Furthermore, it was shown that partial sulphide oxidation (37%) yielded comparable leach recovery (95.8%) to samples significantly more oxidised. It is hypothesised that biological oxidation preferentially oxidised sulphides minerals containing gold, namely arsenopyrite. This suggests that only partial oxidation of the Youanmi ore is required to achieve high gold recoveries through cyanidation.

Albion[®] Test-work

The Albion process is a combination of ultrafine grinding and oxidative leaching at atmospheric pressure. The first step is mechanical liberation using an IsaMill™ to grind the feed particles to a narrow size distribution. The second step is chemical liberation achieved by injecting supersonic oxygen, using the HyperSparge™ injection system, into the base of a series of Albion Leach Reactors to oxidise the gold concentrate.

Albion® Testwork was conducted on three composite samples as part of a 2021 testwork campaign, as previously announced to ASX on 23 December 2021. A summary of results are shown in Table 5 below:

Geo-metallurgical Modelling

==> picture [71 x 67] intentionally omitted <==

Rox has commenced a geo-metallurgical modelling program to further understand the following:

The lithological domains across the ore body;
Variability in gold recovery for different domains; and
Potential relationships between mineralogical characteristics and gold recovery.

To date, analysis of over 1,000 LeachWELL assays have been conducted on RC and diamond intercepts.

Oxidation Amenability and PFS Trade-off Study

The BIOX[®] and Albion[®] Processes are well-known technologies across the global mining industry. BIOX is used at various gold projects around the world, including Agnico Eagle’s Fosterville gold mine in Victoria and Endeavour Mining’s recently commissioned Sabodala-Massawa Project in Senegal. GeoProMining LLC’s, Zod gold mine in Armenia has successfully operated an Albion[®] plant since 2014.

Rox has engaged Maca Interquip and Metso to conduct engineering studies (including capital and operating cost estimates) for the Concentrate Processing Plant, Albion Plant and BIOX Plant.

The results of these studies, coupled with the completed metallurgical testwork, will assist Rox in determining if an oxidation process or a concentrate sales model will form the base case for the PFS.

Albion®	90-91.5%	55-60%	92.3-99%	88.6-95.7%

PFS Completion Timeline

With these engineering studies nearing completion, Rox anticipates that the Pre-Feasibility Study will be completed by the end of July 2024, slightly later than the originally expected completion date of June 2024.

Section 1: Data and Sampling Techniques

Criteria	JORC Code explanation	Commentary
Sampling techniques	Nature and quality of sampling (eg 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.	Sampling consisted of reverse circulation (RC) and half- core NQ2 sized diamond samples. Metallurgical samples were selected and composited by Rox geologists and JT Metallurgical Services metallurgists to best reflect domains within the target mineralisation. These were selected using geological logging information and Fire Assay (Au) grades and ICP (other elements). Metallurgical composites were generated by splitting out using rotary splitter the desired mass of each interval composite. The composite was then thoroughly combined by passing through a rotary splitter three times. All composites were freezer stored in a sealed, labelled bag inside the laboratory
	Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.	The entire RC and diamond (DD) drilling sample was extracted prior to subsampling at surface next to the rig. Diamond and RC field duplicates were taken on selected samples to measure representativity of sample splits.
	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 (eg ‘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 (eg submarine nodules) may warrant disclosure of detailed information.	Industry sampling, preparation and assaying techniques have been used to acquire the current dataset. Sample preparation consisted of coarse crushing a maximum of 3 kg of the submitted sample, pulverising to >85% passing 75 microns and homogenising the pulp. 50 g sample sizes were chosen for analysis of gold, with fire assay fusion and detection by atomic absorption spectrometry (AAS).
Drilling techniques	Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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).	The Youanmi drilling database has been built up over several decades by several different operators. Only RC and DD holes have been used in the resource estimate. The collar table summary is tabulated below.
Drill sample recovery	Method of recording and assessing core and chip sample recoveries and results assessed.	Sample recoveries were recorded by the field geologist in the field during logging and sampling. Core recoveries where available were calculated based on nominal run lengths versus measured length of recovered core. 96% of the recorded intervals have core recoveries > 80%.

		Commentary Limited records relating to historical RC or diamond core sample recoveries have been identified, however, where described, sampling and recovery procedures are consistent with standard Australian industry standards. No relationship between sample recovery and grade has been analysed. The Competent Person considers that the level of detail is sufficient for the reporting of metallurgical results Lithological logging is qualitative in nature. Logged intervals were compared to the quantitative geochemical analyses and geophysical logging to validate the logging. Mineralised intercepts from diamond drillcore were cut using a diamond saw into half-core and sampled on either a 1m basis or over geological intervals from 0.3m to a maximum of 1.2m. RC samples were collected every metre on the drill rig using a cone splitter. A 1.5-3kg sample split was collected into a calico bag for laboratory submission. In some cases, composite samples of up to 5m were collected via spear sampling. Anomalous composite samples were usually re-assayed at 1m intervals where composite assays were greater than 50ppb, 80ppb or 250ppb depending on the program. Sample preparation consisted of drying, riffle splitting samples >3 kg, coarse crushing, pulverising to >85% passing 75 microns and homogenising the pulp. The Competent Person considers these methods appropriate for this style of mineralisation.

		Commentary Metallurgical testwork was conducted at ALS Metallurgy in Perth and Metso South Africa (BIOX®testwork) with all laboratory procedures used being commonly accepted and certified techniques for gold. Solid and Solution samples were prepared and assayed at ALS or Metso South Africa. Duplicate 50g fire assays with an AAS finish were used to determine gold assays. This is a total technique and is considered appropriate for this level of testwork. Quality control was carried out by inserting blanks and standards into the sampling chain. These all demonstrated acceptable levels of accuracy and precision. All Flotation and leach testwork in Perth was conducted in site water sourced from Rox’s Kathleen Open Pit. This water is deemed brackish and best represents future water sources. N/A Historical assay quality control measures are largely unknown. Regular duplicates with satisfactory results were reported from some programmes. The Metana (bulk of historical samples) laboratory appears to have systematically undertaken a 10% duplicate fire assay analysis. No system of submission of standard reference material and blank samples is believed to have been in place at the time of this drilling, in line with local industry practice at that time. Goldcrest took field duplicates, standards and blanks on an approximate 1 in 20 basis (5%) and all Goldcrest drill samples were submitted for assay. Goldcrest twin drilling in shallower areas has verified the drill results of previous explorers. Historical quality assurance and quality control data relating to the remaining resources is either no longer available or is inconsistently reported. Given the long time period over which the data was generated it was not possible to independently verify the quality of the data. Rox took field duplicates at a frequency of 1 in 26 samples and inserted external standards and blanks at a frequency of 1 in 26 samples. Laboratory introduced QAQC samples included coarse reject and pulp repeats and internal standards. Generally, results were precise and accuratewithonly afew inconsistenciesidentifiedin

	Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established.	Historical assay quality control measures are largely unknown. Regular duplicates with satisfactory results were reported from some programmes. The Metana (bulk of historical samples) laboratory appears to have systematically undertaken a 10% duplicate fire assay analysis. No system of submission of standard reference material and blank samples is believed to have been in place at the time of this drilling, in line with local industry practice at that time. Goldcrest took field duplicates, standards and blanks on an approximate 1 in 20 basis (5%) and all Goldcrest drill samples were submitted for assay. Goldcrest twin drilling in shallower areas has verified the drill results of previous explorers. Historical quality assurance and quality control data relating to the remaining resources is either no longer available or is inconsistently reported. Given the long time period over which the data was generated it was not possible to independently verify the quality of the data. Rox took field duplicates at a frequency of 1 in 26 samples and inserted external standards and blanks at a frequency of 1 in 26 samples. Laboratory introduced QAQC samples included coarse reject and pulp repeats and internal standards. Generally, results were precise and accuratewithonly afew inconsistenciesidentifiedin

Criteria	JORC Code explanation	Commentary
Mineral tenement and land tenure status	Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.	The Youanmi mining centre is covered by a Joint Venture agreement with Venus Metals Corporation Limited known as the ‘OYG JV’. This comprises ten granted Mining Leases, with a beneficial interest of Rox 70% and Venus 30%. The leases are M57/51, M57/75, M57/97, M57/109, M57/135, M57/160A, M57/164, M57/165, M57/166 and M57/167
	The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.	There are no impediments preventing the operation of the lease.
Exploration done by other parties	Acknowledgment and appraisal of exploration by other parties.	Gold was first discovered at Golden Crown, just to the south of Youanmi in 1894. Some ore from the area was carted to the government battery at Mount Magnet for treatment. Further prospecting led to the discovery of further deposits in 1905, and production commenced from the United and Hill End mines. The Main Lode was discovered in 1908, and the townsite of Youanmi was gazetted in 1910. Youanmi Gold Mine Limited was floated in 1911 and commenced operations based on the Main Lode. Further discoveries led to the development of the Pollard Lodes and Currans to the south, where a small treatment battery was established. The mine struggled during World War One with a shortage of labour and high costs, and finally closed in 1922. It employed around 100 men. In 1934, the Youanmi Gold Mining Limited was floated in London with the intention of restarting underground mining. Production started in August 1936 and continued until 1942, when a shortage of skilled labour due to World War II, resulted in a second closure. About 200 men were employed in this phase. The maximum vertical depth reached by the workings was about 300m below the natural surface; the average stope width was 1.5m. After 1942 the townsite was abandoned; the only remaining infrastructure is the town cemetery. Eastmet Limited, an 80% owned subsidiary of Metana Minerals NL, entered into a JV agreement with Tantalex Ltd and Franmere Holdings Pty Ltd to earn 50% of a group of tenements at Youanmi. Open mining began in October 1986 and the 600,000 tpa conventional Carbon- In-Pulp plant was commissioned on 31 December 1986, by which time Eastmet had acquired the remaining 50% of the Project. The original tenements covered the Main, Hill End, and Western Laterite open-pits; additional tenements acquired covered the United North, Kathleen, Rebel-Kurrajong and Bunker open-pits and the unmined Commonwealth and Connemara resources. Ore and waste were mined on 2.5m flitches by backhoe excavators and hauled by 50t offroad dump trucks. Exploration and development drilling was completed on a 320m by 10m grid, with the holes inclined -60 to the east and sampled at 1m intervals. Grade control during mining used Ditchwitch trenches cut from west to east spaced 5m apart and sampled at 1m intervals along the trench. Additional RC drilling was used in new areas and at the transition from oxide to fresh ore.

		Commentary After completion of the Main Lode pit in 1989, satellite pits were mined including the high-grade Penny West pit, 28 km to the south. The maximum production rate was 187,000 tonnes per quarter. The peak quarterly gold production was 37,900 oz in September 1991. The plant ceased treatment in October 1992 and mill cleanup continued into January 1993. Between 1990 and 1993 Eastmet completed a programme of deep diamond drilling to test the extensions of Main Lode to a maximum of 750m vertical depth. Gold Mines of Australia Limited (GMA) was created in 1993 when Eastmet, Metana and Paragon Resources NL were merged. In October 1993, the GMA board approved development of the Youanmi underground mine. The ore was processed through a new 220 ktpa flotation and bacterial oxidation circuit, however the operation ultimately failed to achieve production targets, and the underground mine was closed in November 1997. The Youanmi gold deposits are hosted in the Youanmi Terrane. They were formed where a N-striking sequence of high- Fe tholeiitic mafic rocks and BIFs intersects a NNW- striking, variably WSW-dipping high-strain zone interpreted to be a sinistral-normal shear system. The foliation is axial planar to a S-plunging isoclinal synform. Mined deposits lie at various positions on this structure: • Western limb: Bunker, United North (E-dipping stratigraphy) • Hinge: Rebel, Kathleen (S-dipping stratigraphy) • Eastern limb: Hill End, Main Pit (W-dipping stratigraphy) The east limb of the folded mafic sequence is stoped out by the irregular intrusive contact of a large monzogranite intrusion. The exposed monzogranite-mafic contact has low strain, suggesting the intrusion of the monzogranite is late in the folding and formation of the foliation. Interflow sediments are altered chlorite-quartz-magnetite rocks up to several metres thick. These sediments have focused much of the strain and frequently host auriferous shears. The mafics and monzogranite are intruded by intermediate porphyry bodies with complex geometric and timing characteristics. Gold mineralisation and alteration are localised in N- to NNW-striking, and moderately to steeply W-dipping anastomosing shear zones 1m to 20 m thick, averaging 3 to 4m. The mineralogy of the shear zones is sericite- quartz mylonites with abundant sulphides, chlorite and carbonate, with accessory biotite, rutile and apatite. The gold occurs within the pyrite and arsenopyrite, which may be up to 15% of the volume of the mylonite. They are interpreted to have formed relatively late in the geological history of the area, as they crosscut the foliation and the monzogranite. A lesser mineralisation style is quartz vein stockwork lodes within the monzogranite. These trend NNE and are the brittle equivalent of the ductile shear zones in the mafic. The quartz veins are usually steeply dipping and a fewcentimetreswide,with veryhighgrades; coarse
