Venus Metals Corporation Limited: Substantial 39% Increase to Youanmi Gold Resource to 1.7Moz Au

Australian gold and nickel company, Rox Resources Ltd. (ASX:RXL), in conjunction with its joint venture partner Venus Metals Corporation Ltd. (ASX:VMC) is pleased to report a significant increase to the mineral resource estimate 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 independent consultants for both the Youanmi Near Surface and Deeps areas. Widenbar Associates completed the Near Surface Resource (Youanmi Near Surface Deposits Resource Estimate June 2021 - refer Table 1*) while CSA Global completed the Youanmi Deeps Resource Estimate (Report Youanmi Deeps Youanmi Deeps Mineral Resource Estimate June 2021 - refer Table 1*). The previous resource for Youanmi was published in 2018 (Widenbar).

Managing Director Alex Passmore commented: "The release of the updated Youanmi Resource is a milestone for the Company (and the OYG JV) and demonstrates the strong potential to continue to grow high-grade gold resources at the Youanmi deposit. The Company is very pleased with both the expansion of the Deeps Resource as well as achieving a considerable increase in inventory to the Near Surface Resource areas including some spectacular results at Grace which contains 109,000 ounces at an average gold grade of 7 g/t Au at shallow depths. An overall increase in gold resources of 39% is a great result, as is the $16 /oz discovery cost realised to achieve these results.

This resource update also highlights Rox's low enterprise value per attributable resource ounce which based on the Company's last reported cash balance (March 2021) and current market capitalisation is calculated to be only $45 per ounce. On the back of the resource upgrade, we will be commencing the Youanmi Mine Feasibility Study. Drilling will continue at Youanmi with a focus on the ongoing conversion of inferred material into indicated categories for both the Deeps and Near Surface Resources and extension of the Youanmi Deeps along strike and down dip. In addition, regional grass roots exploration drilling will continue on our extensive tenement interests with the intent of making new discoveries in the area."


Comparison to 2018 Resource Estimates (Widenbar 2018):

An overall increase of 39% in contained gold has been achieved, with a 52% increase in metal in the Indicated category, and a 31% increase in the Inferred category (Figure 1 below*). Cut-off grades remained the same as those used in the 2018 estimate (i.e. 4g/t Au for Deeps and 0.5g/t Au for Near Surface) and 1.5 g/t Au was used for Grace.

Youanmi Deeps Resource Discussion:

Twenty-three mineralised lodes were modelled using Leapfrog software for wireframe interpretations, along an approximately 2.2 km of strike length, comprising the Main Lode and associated footwall and hanging wall lodes along the main trend corridor.

The estimation process estimated both the grade-thickness and the intersection thickness using ordinary kriging. The block grades were calculated by dividing the grade-thickness by the estimated thickness (which is not the same as the actual physical thickness of the wireframe interpretation).

The hanging wall and footwall lodes are predominantly 0.5 m to 2.0 m thick, while the Main Lode is generally on the order of 1.0 m to 3.0 m thick, but locally exceeds 10.0 m.

The lode intersections were interpreted based on several characteristics, such as grade, shearing, degree of mylonitisation, veining, sulphide content, or alteration and bleaching. Intervals were generally selected using the assay tables, verified using core photographs and logging, except where historic core was unsampled, in which case lithology tables were used.<

Pinch-outs were applied manually around the peripheries and at roughly half of the average data-spacing, up to 40 m.

To subset the lode interpretations into the higher-grade shoots, a statistical approach was adopted, using Leapfrog to model the grade-thickness variable. The grade-thickness composite dataset was then constrained to those points inside the high-grade shoot models.

As is illustrated in Figure 3, progression from the previously quoted resource (2018) shows significant depth extension below the -340 mRL as well as tightening up the model above this reflecting the different modelling technique applied and demonstrating a more conservative approach along strike. Increased resource tonnage and metal was also due in part to more lodes being identified and interpreted east and west of the main lode.

Resources ounces per vertical metre (OVM) increased significantly in localised areas including in the upper levels (above 210 mRL), and intermediate levels (below 70mRL to -150mRL). In the area between -170 mRL and -290 mRL the updated resource was more conservative in the Inferred category, hence the reduction shown through this area in Figure 6 which shows total OVM, however the Indicated portion through this area increased from 170 OVM to around 940 OVM, which is an impressive result.

For the purpose of block modelling a total of 21 areas were defined with each having their own variogram modelling parameters assigned. The block model grade estimation methodology used ordinary kriging interpolation within Micromine 2021 software. Search distances and orientations were unique to each of the individual areas. The Currans Find deposits used Inverse Distance Cubed estimation methodology as there was too little data for robust variogram calculation.

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 Grace deposit which is high grade and has a relatively high nugget has a higher cut-off grade of 1.5 g/t Au applied to it resulting in a total resource of 490,000 tonnes at 6.95 g/t Au for 109,000 ounces.

This mineral resource estimate includes maiden resources for Grace and Currans Find deposits.


Next Steps

On the back of this resource upgrade the Company has commenced studies into the optimal production scenarios at Youanmi. These studies will feed into a detailed feasibility study which is due for completion in the second half of next year. The various studies include metallurgical test work, development of a geo-metallurgical model, processing plant design, pit optimisation, underground mining optimisation, dewatering and geotechnical studies, waste rock characterisation and environmental baseline testing.

In parallel to the study outlined above the Company is undertaking an extensive regional exploration program and a drilling program in the near-mine area. Ongoing exploration results will be released to the market as they come to hand.

The Company is highly confident that the resource inventory at Youanmi will continue to grow rapidly as results from this program are incorporated into further resource estimates.

About Venus Metals Corporation Limited:

Venus Metals Corporation Ltd. (ASX:VMC) is a West Australian based Company with a focus on gold and base metals exploration. The Company aims to increase shareholder value through targeted exploration success on its projects.

The Company's major gold project is the Youanmi Gold Mine, located 500km north east of Perth. The Youanmi Gold Mine is now jointly owned by Venus Metals (30%) and Rox Resources Limited (70%) (OYG JV); Indicated and Inferred Resources of the mine exceed 1.2 million ounces of gold.

Exciting new discoveries at the Youanmi Gold Mine have been made at the Grace prospect in footwall granites where very high grades of free milling gold have been intersected, including 25m @34.7g/t Au from 143m (RXRC 287) and 13m @60.49 g/t from 181m (RXRC 239). The Grace Prospect may substantially add to the Youanmi Gold Mine resources.
