Youanmi Near Surface Resource Increased to 1.0Moz – Total Youanmi Gold Project Resource Lifts to 3.2Moz

Highlights:

  • Youanmi Near Surface Resource increased by 204Koz Au to 1,004Koz Au
  • This resource upgrade incorporates 16,000m of additional RC drilling above 160m vertical depth and delivers a 26% increase in the Near Surface Resource contained gold.
  • Youanmi Mineral Resource inventory has increased by 93% from 1.7 million ounces (June 2021) to 3.2 million ounces following an intensive exploration campaign throughout 2021 and early 2022.
  • All in exploration costs on a rolling average basis for the project (Underground and Near Surface Resources) since project acquisition indicate an average $7 per ounce discovery cost (approximately $10 per ounce discovery cost for the Near Surface Resource in this update).

West Australian 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 report a significant increase to the Mineral Resource Estimate ("MRE") for the Youanmi Gold Project near Mt Magnet, WA.

Drilling and exploration work at the Youanmi Gold Project predominantly in the OYG JV area (Rox 70% and Manager, VMC 30%) has yielded substantial increases in known and defined tonnages and ounces since acquisition and commencement of drilling in Mid-2019.

Rox has used an independent consultant, Widenbar Associates, to complete the Near Surface Resource estimate (refer Table 1). The previous near surface resource for Youanmi was published in June 2021 (ASX RXL 23 June 2021).

Managing Director Alex Passmore commented:

"We are very pleased to announce this increase to the Near Surface Resource Estimate at Youanmi following the inclusion of newly delineated mineralised zones along the mine corridor including the Link, Footwall Lodes and Hanging-wall Lodes.

The lift in the Near Surface Resource incorporates data from 16,000m of RC drilling undertaken in the second half 2021 and early 2022. The substantial increase in both Near Surface and Underground resources at Youanmi is testament to the strong geological understanding our exploration team has developed, allowing for precise and effective targeting of gold lodes that continues to deliver strong results. The scale of Youanmi is starting to become more apparent and in line with our high level of confidence in the Project.

This resource will underpin the open pit component of the company's Scoping Study which is on track for completion in the middle of the year."

Youanmi Near Surface Resource Modelling Parameters Discussion:

Geology and Geological interpretation

The Youanmi Gold Project is located in the central part of the Youanmi greenstone belt, which is situated in the Southern Cross Province of the Yilgarn Block of Western Australia. The greenstones and surrounding granitoid rocks are Archaean in age. The geology of the Mine Area consists of a north to northwest trending sequence of greenstones. The greenstone succession at Youanmi comprises strongly magnetic tholeiitic basalt, sheared basalt, banded iron formation and mafic schist. The greenstone succession is intruded by an adamellite batholith, called the "Youanmi Granite".

Gold mineralisation represents a typical structurally controlled Archaean shear hosted lode deposit. Mineralisation is hosted in both the Mine Shear Zone, a 1-25m wide shear zone that has been traced along strike for over 2,300m and 900m down-dip, and a series of footwall and hanging wall shear zones. The Mine Shear is subparallel to the greenstone-granite contact and has variable dips of between 30°-70°W striking 330°.

Mineralisation is concentrated along a major flexure in the Mine Shear as it splays of the regionally-extensive Youanmi shear zone. Gold is intimately associated with sulphide minerals and silicates in zones of strong hydrothermal alteration and structural deformation.

Granite hosted gold mineralisation occurs at several sites, most notably Grace and the Plant Zone Prospects, controlled by conjugate structures striking 000°-010° and dipping 60-70°W. Plant Zone mineralisation is associated with stockwork quartz veining, within a deeply weathered granite host. Mineralised envelopes extend over a strike length of at least 1,400m, lying subparallel to the Mine Shear Zone but several hundred metres inside the granite contact. At Grace, the mineralised structure consists of a moderately W-dipping shear zone and silica-stibnite-Au breccia-style veins within sericitized granite.

Drilling techniques

Where recorded by previous explorers, RC drilling was carried out using a face-sampling hammer. Various drilling contractors were used over the years.

RC drilling by Rox was carried out with a 140mm face sampling hammer.

Most historical diamond drilling was undertaken using an NQ diameter bit.

Diamond drilling completed by Rox was undertaken using a combination of HQ and NQ2 diameter bits. Precollars for diamond holes were drilled using 140mm face sampling RC hammer.

RC and diamond down-hole surveys were completed using north-seeking gyroscopes.

Sampling and sub-sampling techniques

Historical RC samples were collected every metre via a cyclone into a plastic bag prior to splitting with a Jones riffle 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.

Historical diamond drill core was cut using a diamond saw into half-core or, in the case of HQ diameter core into ¼ core and sampled on either a 1m basis or over geological intervals to a maximum of 1m. Core was stored at the Youanmi mine site. Historically, information relating to sample recovery and quality, while often noted on logs, was not always well documented.

RC sampling by Rox was undertaken by collecting 1m using a cone splitter. RC samples, 1m samples were taken through target zones. 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.

Rox 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 laboratory and one half retained.

Sample Preparation and Assaying

Assaying methodology and laboratories have varied over the years with several historical operators. Standard industry practice sampling, preparation and assaying best practises were used at the time. The typical analytical technique was fire assay fusion and detection by atomic absorption spectrometry.

Rox RC and diamond core 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. Pulps were analysed by 50g Fire Assay with ICP-OES (Intertek code FA50/OE).

Estimation Methodology

A total of 21 mineralised wireframes were modelled comprising the Mine Lode and associated footwall and hanging-wall lodes. The wireframes were created in Seequent Leapfrog Geo mining software ("Leapfrog") using a combination of logged geology and gold grade to identify the mineralised intervals in drill holes. Merged tables of assay and lithology were created in Leapfrog and the interval selection function was used to code the intersections as belonging to one of the mineralised lodes. No minimum or maximum thickness values were applied for interpretation of the lodes.

The mineralisation wireframes used for the previous January 2022 Youanmi Underground Mineral Resource were updated with the additional assays received since the date of the previous database. The wireframes have all been terminated by the base of oxidation surface. Above this surface (ie in the oxide zone) and outside the area of the wireframes, indicator modelling has been used to define mineralisation.

Near Surface Resources by Area

Probability plots and histograms were used to confirm that domaining produced consistent data sets and to generate top cuts. Analysis was undertaken for composite data inside the mineralisation wireframes. High grade cuts (top cuts) were applied that ranged from 8 g/t Au to 60 g/t Au. A 125g/t Au top was used for the Grace deposit.

The resource estimations were generated using Ordinary Kriging Interpolation techniques, using Micromine 2022 software. Higher grade outlier samples were cut on an area basis. Parent cell block sizes were 5m x 10m x 5m, rotated to a strike of 330°. Sub-celling was used to honour geological, open pit and underground void boundaries. Model interpolation honoured the mineralisation boundaries, with only composites within a domain being used to estimate that domain. Cut-off grades remained the same as those used in the 2021 estimate, (0.5g/t Au for Near Surface Deposits). The Grace deposit which is high grade and has a relatively high nugget has a higher cut-off grade of 1.5 g/t Au.

Block model validation was carried out in several ways, including visual inspection on sections, long sections and plans, and in 3D, model vs composite statistics, swathe plot validation with all validation methods producing reasonable results.

The Mineral Resource was classified as Indicated or Inferred based on the level of geological understanding of the mineralisation and the drill hole spacing. Drill hole sample spacing was the primary metric with Indicated Resources classified where sample spacing was 40m or less. The Inferred classification generally represents areas with drill hole spacing 40m to 75m apart.

Mining and Metallurgical Methods

It has been assumed that the Youanmi Near Surface Deposits will be mined by conventional open pit methods. No dilution has been built into the resource model.

No assumptions have been made about metallurgical factors. The oxide ores at Youanmi are essentially free milling, with historic oxide plant performance via the conventional CIP circuit demonstrating an average gold recovery of 89.4% over the seven years of operation.

A pilot plant trial from October 1993 to July 1994tested three bulk samples of concentrate. Afterbacterial oxidation, recoveries up to 99% wereachieved.
The performance between 1995 and 1997 ofthe flotation and bacterial oxidation circuit wasgenerally lower than budgeted due almostentirely to below budget ore deliveries. Althoughthe plant rarely achieved its full capability, itconsistentlyexceededtheprojectedmetallurgical recovery of 81%, with an averagerecovery of 87.5%.
Blending of ore was not anticipated prior tocommissioning and feed variability createdsignificant problems for both the flotation andbacterial oxidation circuits.
Operating performance history demonstrates asteadilyincreasingrecovery,withinitialcommissioning values of 85% increasing rapidlyto a maximum of 92.4% in 1994-95. This isindicative of improving metallurgical control anddiminishing amounts of reactive sulphide fromtransitional zones. Based on historical operatingdata, one of the most significant factorsaffecting both throughput and recovery wasmechanical and equipment failures within thebio-oxidation circuit.
