High Grade RPM Gold Exploration and Plant Design Purpose
Melbourne, Mar 3, 2022 AEST (ABN Newswire) - Nova Minerals Limited (
ASX:NVA) (QM3:FRA) (NVAAF:OTCMKTS) has defined a number of exciting targets at the High-Grade RPM Gold Project to increase and prove-up the current Inferred Resource. The aim of the extensive drilling program planned for 2022 is to delineate additional high grade Indicated Resources at the RPM Project to include in the production schedule through the Korbel Central Processing Facility as designed in the Scoping Study (ASX Announcement: 28 February 2022). The RPM high grade resource provides an exciting opportunity to deliver a higher average mill feed grade and substantially increase and improve the gold production profile over the life of the project.
Highlights
- Phase 1 - Two rigs drilling 5,000m at the RPM North Deposit to infill around RPM-005 (132m @ 10.1 g/t Au) - (RPM-005 returned an overall average grade of 3.5 g/t Au over 400m from surface within the RPM North mineralized zone (ASX Announcement: 11 October 2021)) and the current Inferred Resource of 23mt @ 2g/t for 1.5Moz (ASX Announcement: 27 October 2021) to prove it up to the higher confidence Indicated status to include in the production schedule immediately.
- Phase 2 - Three rigs drilling 15,000m at the RPM North Deposit to step-out in order to increase the current resource which remains wide open along strike, depth, and thickness, as well as initial drilling to test the highly prospective RPM South zone which shows a much larger surface footprint from rock chip sampling and geological observations.
- The initial Scoping Study represents a starter operation that provides a solid platform for growth and identifies clear opportunities for improvements, which the company now intends to aggressively pursue. The Korbel Central Processing Facility, as designed in the Scoping Study, provides the flexibility to schedule feed from numerous ore sources that are expected to come online over the life of the Project. Inclusion of the high-grade RPM resources to feed the centralised 6Mt pa Mill, in order to take advantage of the high sensitivity to grade as outlined in the Scoping Study (ASX Announcement: 28 February 2022), is a priority to greatly improve the overall project economics.
- The gold production rate and project mine life have the potential to grow significantly with continued resource definition and expansion, as demonstrated in recent announcements at the Korbel and RPM Projects, and ongoing exploration activities across the wider Estelle Gold Trend, with a clear early focus to prove up the high grade 1.5Mozs @ 2.0g/t Au resource at the RPM North Deposit to the Indicated category as well proving further Indicated and expanding the resource at Korbel.
Nova CEO, Mr Christopher Gerteisen commented: "The Company reached a major milestone in the recent announcement of its maiden Scoping Study (ASX Announcement: 28 February 2022).
While constrained by the amount of Indicated Resources available from a single ore source within a starter pit at Korbel Main, we were very pleased to report strong and positive results that shows the flow sheet we have developed works better than expected and can support a viable project with exceptional flexibility to maximise opportunities from multiple ore sources that will ultimately come online as we continue to develop the Estelle Gold Trend.
To clear up the CAPEX component, Korbel Main is a key to the rapid development of the Estelle Gold Trend and has now demonstrated itself as a viable standalone project expected to contribute a significant portion of future gold production utilising a centralised processing infrastructure which is scaled for the greater project to receive feed from multiple ore sources from across the entire Estelle Gold Trend as the years progress.
While this ore feed will initially mainly come from the Korbel and the high-grade RPM Deposits, where we have existing resources that will come online sooner in the production profile as studies are completed, later it is anticipated that ore feed will also come from the Train, Shoeshine, and Stoney prospects, as well as from additional discoveries that we expect to be made in the future. One must understand the big picture and potential that Nova is developing a Gold Trend which is endowed with numerous deposits that will eventually be sources of ore to feed into the Korbel Central Processing Facility as designed in the Scoping Study. As we move forward, it is expected that minimal extra capital expenditure will be required, mainly going towards material haulage infrastructure to bring in ore from sources across the Project area to the centralised Korbel Plant site.
There is no continual capital expenditure or upsizing required of the plant as the flexibility in feed grade from ore sorter grade control and multiple ore sources from deposits across the Project area will give us the desired increase in NPV and IRR, and resiliency in outside market forces, as illustrated in the sensitivity analysis in figure 2* below."
Scoping Study Plant and Infrastructure Design
Nova's initial plant design of a 6Mt pa mill throughput rate and associated CAPEX was considered for these future resources and throughput with the sensitivity analysis (Figure 2*) showing the Project to be resilient to changes in capital costs and recoveries, with significant leverage to improved head grade, particularly high-grade RPM mill feed proposed to be added into the mining and key assumptions in short order.
The Scoping Study released on 28 February 2022 represented a snapshot in time to assess a Korbel Main starter pit scenario and did not include potential resource extensions at either the Korbel or RPM Deposits that have been announced since the current Korbel Main MRE was completed in December 2021. The study did however allow clear provisions in the CAPEX for a higher feed grade as pointed out in the paragraph above. Material handling studies are well underway to haul the material to the planned Korbel Central Processing Facility (Figure 3*).
High Priority Targets for Diamond Drilling at the High-Grade RPM North Project
Nova's initial targeted drilling program has clearly defined significant zones of gold mineralisation along and adjacent to the high-grade RPM North Deposit's 1.5Moz Inferred Resource zone (Figure 1*) to move resources into the Indicated category. Of particular interest is the area immediately along strike to the west of the RPM-005 (132m @ 10.1 g/t Au) - (RPM-005 Returned an overall average grade of 3.5 g/t Au over 400m from surface within the RPM North mineralized zone (ASX Announcement: 11 October 2021)) where a number of holes are planned to be drilled to produce an interim resource expansion to the Indicated category and increase the tonnages.
A number of these exciting new targets that have been identified for future drilling coincide with an extensive zone at the RPM South Prospect which will be drill tested later in the year.
Subject to weather, it is anticipated that drill rigs will be onsite at the RPM Project in April.
