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.

Youanmi has a Total Mineral Resource of 1,656 koz of contained gold, with potential for further expansion with the integration of existing prospects into the Resource and further drilling. Youanmi was a high-grade gold mine and produced 667,000ozof gold (at 5.47 g/t Au) before it closed in 1997. Youanmi is classified as a disturbed site and is on existing mining leases which has significant existing infrastructure to support a return to mining operations.
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
MET061: (Upper) Youanmi Deeps
Classified as a pyrite quartz muscovite schist.
Eight gold occurrences were seen, all low-silver gold. Four as fine grains (6 - 15μm) in pyrite and four as grains in silicate matrix.

| 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. |
