Youanmi Deeps Metallurgical Testwork Achieves 96% Gold Extraction

Highlights:

  • September 2021 testwork delivers substantial improvement in gold extraction for Youanmi Deeps
  • Historical production averaged 86.8% gold recovery, with new testwork improving extraction to 95.6%
  • Testwork overseen by OMC (Orway Mineral Consultants) and draws on new methodologies not previously utilised at Youanmi
  • Como Engineers engaged to complete scoping level process plant design and costing - work commenced September 2021

___________________________________________________________

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 metallurgical testwork recently conducted on the Youanmi Deeps Resource, located within the OYG JV area (Rox 70% and Manager, VMC 30%).

The work forms part of development studies currently underway into potential future production at the Youanmi Gold Project. This preliminary part of the study will establish processing pathways to optimise gold recovery prior to progressing to more extensive and detailed "feasibility study level" metallurgical testwork.

Managing Director Alex Passmore commented:

"In June 2021 (ASX release 23 June 2021) we reported a 30% increase in the Youanmi Deeps Resource, and now we are pleased to report that advances in gold extraction technology over the last 30 years (since GMA built its processing plant) have made a significant difference in gold recovery.

"Preliminary metallurgical testwork indicates a 10% increase on historical gold recoveries by utilising a pressure oxidation leach process (i.e. POX).

"Furthermore, we look forward to results of (scoping level) process plant design and costing later this year being undertaken by Como Engineers who have a long track record of success for both design and development of similar sized gold processing facilities in WA with a variety of flowsheet designs."

Comparison to Historical Data

The principal past producer at Youanmi, Gold Mines of Australia (GMA) operated the Youanmi Deeps underground mine in the 1990s. At which time GMA also operated a 600ktpa oxide ore CIL plant configured to handle 270ktpa of sulphide (i.e. Youanmi Deeps) feed through a bacterial oxidation plant (Bachtech technology). During this period the operation achieved an average of around 87% metallurgical recovery up until the plant shut down in November 1997 (Figure 1).

Figure 1: Large improvement on historical treatment recovery

Rox's September 2021 testwork results included two composite samples taken from 30 individual diamond drill core intervals of historical drilling comprising of mainly half and quarter NQ drilling core, including 14 sections from the upper part of the Hangingwall Lode domain, and 16 sections from the upper part of the Main Lode domain. The Main Lode, and Hangingwall Lode domains combined represent over 30 percent of the entire Deeps Mineral Resource. Figure 2 and Table 2 contain the drill hole locations and sample intervals of the composites used in this metallurgical analysis.

Processing Plant Scoping Level Study

Como Engineers have been engaged to conduct scoping level design and costing including capital cost estimate and operating cost for a processing plant solution which will include utilising parts of the existing 1990s circuit where appropriate into a new build located away from the recently discovered Grace mineralisation.

The flowsheet design is based on utilising a standard crushing and grinding circuit to 75 microns, before performing conventional flotation to extract the high gold grade sulphides, after which float concentrates are reground to 15 microns before undergoing a pressure oxidation leach process to liberate gold at very high recovery rates. Float tails will also be leached to ensure highest possible gold recoveries overall.

The scoping level design work is based on a small processing plant of just 300 ktpa capacity incorporating a relatively small Pressure Oxidation Leach (POX) circuit as the base case option being considered. The size of the POX circuit is small comparable to other low grade high tonnage operations for two main reasons. Firstly, very low mass pulls achieved of under 15%, and secondly, the low tonnage nature of the plant required to treat very high head grade material from the Deeps Resource (noting resource grade is over 7.5 g/t Au).

Other oxidation process technologies are still under consideration to establish the most economically feasible solution going forward.

Relevance of Testwork to Youanmi Resource

It is noted that this early stage testwork is relevant to the Youanmi Deeps Resource (ASX release 23 June 2021) which comprises just over half the total resource of 1.7 mil ounces (refer Table 3 below).

Next Steps

The testwork has demonstrated a well understood pathway to very high gold recoveries, something which was not achieved in the 1990s, and further testwork in combination with the costing studies will determine the optimal and most economical feasible process solution, exploring various other suitable processes.

Further testwork in combination with the costing studies will determine the optimal and most economical feasible process solution. The additional testwork is not only recovery related.

Incremental capital cost versus gold recovery analysis outcomes are being continuously examined with current flow sheet scenarios.

Future work is planned to include a wider range of underground resource domains for which the OYG JV has abundant samples in the form of diamond drill core, including the recently discovered Link area to the north of the current deeps resource, which after geological modelling has been completed will be included in the next resource update.

Appendix 1

Petrographic Analysis

Introduction

Petrographic analysis was completed on 11 sulphide rich diamond core samples across the Youanmi deposit with the aim of determining the mode of occurrence of gold within various ore zones. Preparation of 11 polished thin sections and petrographic descriptions were completed by Diamantina Laboratories in Perth.

Report Summary

Visible gold was observed in all samples. Gold particles sizes range from 2-150μm. At least three gold species occur in order of abundance:

  • Low-silver gold, is most prevalent, primarily on pyrite grain boundaries and with silicates and occasionally in micro-fractures and cavities; grain sizes from 10-150μm
  • Argentian gold (silver-rich); within pyrite grains that lie in and/or along fractures and cavities; finegrained (<10-20μm)
  • Aurostibnite (Sb-rich), quite rare, very-fine grained (<10μm) in silicate matrix

The majority of gold particles observed occur on pyrite grain boundaries, with silicates and in both cavities, on grain boundaries and micro-fractures. This is important as gold particles not included within sulphide grains are more likely to be free milling. Only two examples of gold with arsenopyrite were observed. The gangue mineralogy is predominantly quartz, sericite and dolomite. The sulphides are dominated by pyrite and lesser arsenopyrite, with uncommon stibnite.

Petrographic Descriptions and Microphotographs

Sampling of diamond holes was by cut halfcore as described further below.
handheld XRF instruments, etc). These examplesshould not be taken as limiting the broad meaning ofsampling. Drill holes were generally angled at -570 towards gridnortheast (but see Table 2 for individual hole dips andazimuths) to intersect geology as close to perpendicular aspossible.
Include reference to measures taken to ensure samplerepresentivity and the appropriate calibration of anymeasurement tools or systems used 30 drillhole location sections were selected including 14sections from the upper part of the Hangingwall Lodedomain, and 16 sections from the upper part of the MainLode domain. The selection was based on providing arepresentative diamond drill holes that each represent atleast 20% of the proposed mining and mill feed inventory.
Aspects of the determination of mineralisation that areMaterial to the Public Report. In cases where 'industrystandard' work has been done this would be relativelysimple (e.g. 'reverse circulation drilling was used toobtain 1 m samples from which 3 kg was pulverised toproduce a 30 g charge for fire assay'). In other casesmore explanation may be required, such as wherethere is coarse gold that has inherent samplingproblems. Unusual commodities or mineralisationtypes (e.g. submarine nodules) may warrant disclosureof detailed information Diamond core was cut according to lithological intervals anddispatched to the laboratories. Sampling protocols andQAQC are as per industry best practice procedures.
Drillingtechniques Drill type (e.g. core, reverse circulation, open-holehammer, 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 diamond core (DD). The DD holediameter was predominantly half and quarter NQ drillingcore size diameter. Hole depths reported range from 50m to215m to 745m for diamond.
Drill samplerecovery Method of recording and assessing core and chipsample recoveries and results assessed Limited records relating to diamond core sample recoverieshave been identified. The sections selected from the MainLode, and Hangingwall Lode domains combined representover 30 percent of the entire Deeps Mineral Resource. Thisis above the target threshold for this analysis.
Measures taken to maximise sample recovery andensure representative nature of the samples Diamond Drilling sampling documentation where availabledescribed, sampling and recovery procedures consistentwith standard Australian industry standards (Yeates, R.J.2003).
Whether a relationship exists between samplerecovery and grade and whether sample bias mayhave occurred due to preferential loss/gain offine/coarse material. There is no observable relationship between recovery andgrade, and therefore no sample bias.

Orientation ofdata in relationto geologicalstructure Whether the orientation of sampling achieves unbiasedsampling of possible structures and the extent to whichthis is known, considering the deposit type. The mineralisation strikes generally NNW-SSE and dips tothe west at approximately -50 degrees. The drill orientationwas 065 and 245 degrees and -60 to -90 dip. Drilling isbelieved to be generally perpendicular to strike
If the relationship between the drilling orientation andthe orientation of key mineralised structures isconsidered to have introduced a sampling bias, thisshould be assessed and reported if material. No sampling bias is believed to have been introduced.
Sample security The measures taken to ensure sample security. The chain of custody for historical samples is not welldocumented, but was reviewed by RSG (Yeates, 2003) andfound to be consistent with the standard practice for thetime.A large number of samples these bags were transported bythe Company directly to the assay laboratory. In somecases the sample were delivered by a transport contractorthe assay laboratory. The assay laboratory audits thesamples on arrival and reports any discrepancies back tothe Company. No such discrepancies occurred.
Audits orreviews The results of any audits or reviews of samplingtechniques and data. Goldcrest conducted a thorough review of historicalsampling and assay techniques and data in September,2004.No other sampling audits have been carried out to date

Geology Deposittype,geologicalsettingandstyleofmineralisation. The Youanmi Project straddles a 40km strike length of theYouanmi Greenstone Belt, lying within the Southern CrossProvince of the Archaean Yilgarn Craton in WesternAustralia.The greenstone belt is approximately 80km long and 25kmwide, and incorporates an arcuate, north-trending majorcrustal structure termed the Youanmi Fault Zone.This structure separates two discordant greenstone terrains,with the stratigraphy to the west characterised by a series ofweakly deformed, layered mafic complexes (Windimurra,Black Range, Youanmi and Barrambie) enveloped bystrongly deformed, north-northeast trending greenstones.Gold mineralisation is developed semi-continuously in shearzones over a strike length of 2,300m along the westernmargin of the Youanmi granite.The Youanmi gold lodes are invariably associated with a highpyrite and arsenopyrite content and the primary ore ispartially to totally refractory.There are a series of major fault systems cutting through theYouanmi trend mineralisation that have generated somesignificant off-sets.The Youanmi Deeps project area is subdivided into threemain areas or fault blocks by cross-cutting steep south-easttrending faults; and these are named Pollard, Main, and HillEnd 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 quartzsericite altered granite shear zones.The Commonwealth-Connemarra mineralised trend iscentred 4km northwest of the Youanmi plant. The geologycomprises a sequence of folded mafic and felsic volcanicrocks intercalated with BIF and intruded by granite along theeastern margin. Gold mineralisation is developed over a600m strike length, associated with a north trending andsteeply west dipping shear zone that traverses the northwesttrending succession.

Data aggregationmethods In reporting Exploration Results, weighting averagingtechniques,maximumand/orminimumgradetruncations (e.g. cutting of high grades) and cut-offgrades are usually Material and should be stated. Only selected sections were assayed in this set ofmetallurgical testwork
Where aggregate intercepts incorporate short lengths ofhigh-grade results and longer lengths of low-graderesults, the procedure used for such aggregation shouldbe stated and some typical examples of suchaggregations should be shown in detail. Mineralisation over 0.5g/t Au has been included in theselected sections of diamond core.
The assumptions used for any reporting of metalequivalent values should be clearly stated. No metal equivalent values have been used or reported.
Relationshipbetweenmineralisationwidths andintercept lengths These relationships are particularly important in thereporting of Exploration Results.If the geometry of the mineralisation with respect to thedrill hole angle is known, its nature should be reported.If it is not known and only the down hole lengths arereported, there should be a clear statement to this effect(e.g. 'down hole length, true width not known'). The mineralisation strikes generally NNW-SSE and dips tothe west at approximately -50 degrees. The drill orientationwas 065 and 245 degrees and -60 to -90 dip. Drilling isbelieved to be generally perpendicular to strike. Given theangle of the drill holes and the interpreted dip of the hostrocks and mineralisation (see Figures in the text), reportedintercepts approximate true width.
Diagrams Appropriate maps and sections (with scales) andtabulations of intercepts should be included for anysignificant discovery being reported These shouldinclude, but not be limited to a plan view of drill holecollar locations and appropriate sectional views. Appropriate maps and sections are available in the body ofthe report.
