    Anchorage, Alaska, Oct. 09, 2024 (GLOBE NEWSWIRE) -- Nova Minerals Limited (“Nova” or the “Company”) (NASDAQ: NVA) (ASX: NVA) (FRA: QM3) is pleased to announce further high-grade intercepts from the first eight holes of the 21 hole reverse circulation (RC) drilling program conducted in the RPM starter pit area in 2024, within its over 500km2 flagship Estelle Gold Project, located in the Tintina Gold Belt in Alaska. The shallow drilling program was focused on near surface mineralization <50m in depth in support of the RPM starter mine Feasibility Study (FS) currently underway.

    Highlights

    • Results from shallow infill and step-out drilling confirms continuity of near surface high-grade mineralization at RPM North with multiple broad intersections grading > 5 g/t Au from surface and sample interval grades up to 39 g/t Au
    • High-grade gold intersections targeting near surface mineralization above the current high-grade Measured and Indicated core continue at RPM North with all holes ending in mineralization. Significant results include (Table 1 and Figures 1 and 2):
      • RPMRC-24005                                                                 
        • 43m @ 4.4 g/t Au from 2m including;

    • Assay results from the over 500 soil and 225 rock samples collected as part of the extensive 2024 surface exploration and mapping program targeting gold, antimony and other critical minerals from traverses at Stibium, Wombat, West Wing, Muddy Creek, RPM, Styx, and the new claims added in 2023, will be reported by area once received and processed.
    • Resource update including both the 2023 and 2024 drill results to be completed once all results are received.
    • RPM starter mine Feasibility Study (FS), and updated economic study of the Estelle wide project in progress, with the aim to commence with a smaller scale, low capex, high-margin starter mine at RPM as soon as possible, which will provide cashflow to fund the expansion of the larger Estelle project organically.
    • Whittle Consulting engaged to complete project optimization, METS Engineering engaged to complete metallurgical and process design work, and Roughstock Mining engaged for pit and engineering design.

    Nova Minerals CEO, Mr Christopher Gerteisen commented: “These results speak for themselves and we believe will add considerable value to the upcoming resource update and ultimately the FS which will be focused on RPM as a scale-able low capex/high margin project with future expansion plans achieved through cashflow as soon as possible.

    With further 2024 drill results to follow in short order, these results, along with the 2023 drilling will be included in the upcoming resource update. We look forward to updating all stakeholders on these fronts as we continue to progress on our path towards production and early cashflow at RPM within the greater Estelle gold and critical minerals district.”

    RPM Drilling Discussion

    A total of 21 RC holes were drilled at RPM as part of the 2024 drilling program, of which assay results for eight holes have now been received and are reported in this announcement. The drilling was focused on near surface mineralization <50m in depth and had two main objectives.

    1. The first and primary objective was to infill and prove up near surface inferred resources that define the up dip extension of the steep to vertical dipping RPM North high-grade core zone. A new drill pad (Pad 24-1) was located between the two previous drill pads (Pad 1 and Pad 23-1) at RPM North to fill this data gap and prove up this high-grade material (Figures 1 and 2). The initial assay results from holes RPMRC-24005 to RPMRC-24008 indicate this objective was achieved.
    2. The secondary objective of the shallow 2024 drill program was to extend drilling to the South and Southwest of the current RPM North resource to begin to test a potential link with the RPM Valley zone situated approximately 150m to the Southwest. Highly prospective mineralized intrusive rocks have been observed in this area in recent geological mapping and confirmed with anomalous surface sample results. The results returned from holes RPMRC-24001 to RPMRC -24004 indicate the RPM North deposit remains wide open to the South-Southwest and is potentially connected to the RPM Valley zone (Figures 1 and 3). This warrants further follow-up diamond drilling to test the considerable resource upside potential.

    These latest results continue to prove up areas of thick intervals of high-grade gold mineralization (+2g/t) within the existing RPM North resource area, confirming the continuity of the high-grade bonanza core zone, as well as indicating the potential for significant extensions to the existing resource. A representative cross-section (Figures 2 and 3) clearly shows the latest drill holes intersecting up and down dip continuity to mineralization outside of the current resource grade shell. This has the potential to significantly grow the resource in the upcoming MRE update.

    Geological observations also indicate the mineralized intrusive unit is a steeply dipping funnel shaped body which flares out to have a wider footprint near the surface where substantial up-dip potential remains.

    In the central core zone where the intrusive unit is thick and continuous the deposit remains wide open with further significant resource upside potential, up-dip, down-dip, and throughout the intrusive, particularly to the South which remains largely untested by drilling.

    The majority of the holes drilled in 2024 were collared in granodiorite intrusive rocks, the primary host of mineralization at RPM. The granodiorite-hornfels contact was intercepted to the north from Pad 24-1 and to the south from Pad 23-1 where gold mineralization is encountered in both the intrusive and the hornfels. The drillhole intersections as well as observed outcrop between these two drill pads consist entirely of granodiorite crosscut by quartz-tourmaline-sulfide veins, with massive quartz zones of over 1-m thick hosting samples up to 291 g/t Au.

    Estelle Next Steps

    Estelle is a major mineralized trend, hosting gold, antimony, silver, copper, and other critical elements and Nova is working to begin production as early as possible with the potential to operate for decades supplying the minerals the world needs.

    A Feasibility study has commenced for RPM with METS Engineering engaged for metallurgical and process design, RoughStock Mining for pit and engineering design, and Whittle Consulting for complete project optimization, from starter operation with the view of minimizing capex, to finding a steady state mine plan to clear expansion plans. The studies currently underway have the objective of:

    • Getting RPM into production as soon as possible
    • Early year low capex with high margin to fund expansion of the greater Estelle Project
    • Optimized mine plan for highest grade with least strip material for early years
    • Pit Slope scope and design
    • Optimum flow sheet design to increase recovery whilst decreasing reagents to bring down operating costs
    • Plant size, design, and location

    In addition, the Company is also very aware of the value of a domestically sourced critical mineral antimony, and in parallel with the above plans in the FS, we are also looking at our antimony discoveries at both Stibium and Styx in particular from many angles with multiple parties to potentially establish a small scale, stand-alone, quick start up antimony-gold mine, with potential US Dept. of Defense (DoD) support to fully secure the US supply chain.

    Data Verification

    For the 2024 reverse circulation drilling program, 1.52m chip samples were riffle split (dry) to obtain 3-5 kg samples at the drill site, these samples were crushed to achieve >90% passing a 2mm sieve and split down to 225 g to 275 g samples at Nova’s on-site prep facility. Samples were then sent to ALS Fairbanks for additional prep and chemical analysis. Field duplicates (RC) for recent data were collected every 1 in 20 samples at the same time using the same method (riffle split) as the parent sample. Blank material was inserted 1 in 40 samples. Standard Reference Material (SRM) was inserted 1 in 20 samples. Three different SRMs at three different grades levels were used.

    ALS is a certified commercial laboratory and is independent of Nova Minerals. Gold analyses were completed by Au-ICP21 which is gold by fire assay and ICP-AES. For overlimits greater than 10 g/t Au analyses were completed by fire assay and gravimetric finish.
