Anchorage, Alaska, July 31, 2024 (GLOBE NEWSWIRE) — Nova Minerals Limited (“Nova” or the “Company”) (NASDAQ: NVA, NVAWW) (ASX: NVA) (OTC: NVAAF) (FSE: QM3) is pleased to announce the commencement of resource definition drilling and exploration field programs on its over 200mi2 flagship Estelle Gold Project, located in the prolific Tintina Gold Belt in Alaska.
The Company is focused on Feasibility Study (FS) stage drilling at the high-grade RPM deposit to continue to increase and prove-up resources to the higher confidence Measured and Indicated categories. With a total defined 5.2 Moz Au in-pit constrained S-K 1300 compliant resource (Table 1) across 4 deposits, the Estelle Gold Project has development optionality in terms of initial project size and scale, which is subject to market conditions and strategic partners to meet our objective of ultimately growing the Estelle Gold Project into a tier 1 gold producer. The Feasibility Study currently underway is considering a strategy to achieve production with a scalable operation, by:
| 1. | Establishing an initial low capex smaller scale operation at the high-grade RPM deposit requiring less infrastructure for expected early cashflow and high margins to potentially self-fund expansion plans; and/or |
| 2. | Develop the higher capex larger mining operation for increased gold production, cash flow, and mine life that potential future large gold company strategic partners have expressed an interest. |
Work Plan and PFS Highlights:
| ● | Resource Drilling. Program focused at RPM to increase and prove-up resources as part of the Feasibility Study utilizing the company owned drill rig to achieve a cost efficient program (Figures 1 to 5). |
| ● | Mineral Resource Estimate (MRE). Update to include the 2023 and 2024 drilling data and to incorporate the higher gold price for an updated resource. |
| ● | LIDAR. Detailed survey across the property to enable detailed infrastructure design, mineral reserve classification, exploration, etc. |
| ● | Heap Leach. Metallurgical test work is currently underway with METS Engineering to include a low-cost gold recovery method option in the flow sheet for processing lower grade ores to potentially substantially reduce capex and increase the gold production profile. |
| ● | Geotechnical. Detailed studies are underway to potentially increase pit slope angles further. Early indications show very competent geology, with the study results expected to have a significant positive impact on the project economics. |
| ● | Ore Sorting. FS level test work to commence to investigate the additional benefit of using Steinart multiple sensor technologies and further improve on previous exceptional results from utilizing XRT density sorting. Ore sorting results to date have shown the potential to significantly improve resource extraction providing processing optionality, which is expected to reduce overall processing costs, increase total gold production, and increase the life of mine. In addition, planning is underway to complete a future 200kt bulk pit pilot test program to further de-risk ore sorting and optimize material handling and flow. The expected benefits of ore sorting to improve project economics include: |
| ○ | Pre-concentration of mill feed by separating it into high-grade, low-grade and waste fractions | |
| ○ | Selective high grading of lower grade ores and existing waste dumps | |
| ○ | Reduction of environmental risks and costs – smaller tailings dam footprint | |
| ○ | Optimization of multiple process streams, for example, sending appropriate ore to the mill and heap leach | |
| ○ | Pre-concentration of ore in order to reduce transportation costs | |
| ○ | Lowering operating costs | |
| ○ | Improving ore grade |
| ● | Critical Elements. In addition to copper and silver, highly elevated concentrations of Antimony and other critical elements have been discovered at numerous prospects across the Estelle Project. These elements have the potential to provide significant by-product credits to the project. The Company continues to include multi-element analysis for all samples to define these resources for potential future extraction from the gold processing waste stream, and/or as a stand-alone small-scale operation for near term cash flow, i.e. for antimony production which is found in prospects outside of the existing gold deposits. The Company continues to pursue this opportunity as well as federal and state grants for critical minerals development studies and extraction/refining plant capital requirements. The US Government is engaged in providing grant funding and support through the Defense Production Act (DPA) and other legislation to establish and fully secure US domestic critical minerals supply chains which are currently controlled by foreign adversaries. The Estelle Gold Project with its potential of contained critical mineral resources and other key project aspects could contribute to achieving these US national security objectives. |
Nova CEO, Mr Christopher Gerteisen commented: “In less than 5 years we have taken the project from green fields to a total 5.2 Moz Au in-pit constrained S-K 1300 compliant resource with a FS now in progress. We have focused defining high confidence resources for conversion to reserves at 2 deposits, RPM and Korbel, from the over 20 prospects across the Estelle Gold Project on our path towards production. Now in the FS stage, the asset is progressing towards development with our strategy reflecting the flexibility of the project to current market conditions and our commitment to balance sheet management, with a low-capex, expected high margin, scalable start-up operation with potential self-funded expansion and/or a strategic partner to advance the full-scale production scenario to ultimately realize our goal of becoming a tier 1 gold producer with the Estelle Gold Project.”
This strategy provides a defined path to production designed to provide free cashflow, while potentially allowing us to continue to unlock the district organically and to deliver on our prior track record of resource growth, new discoveries, at a low-cost per discovery ounce.”
2024 RPM Drill Plan
Highly targeted and strategic drilling at the RPM deposit continues, with the Company owned Reverse Circulation (RC) rig working to upgrade and expand the current resource. Of the drilling planned for 2024, the majority will be allocated to advance the RPM high grade starter pit area and to further delineate the at-surface, high-grade (1 g/t Au to > 5 g/t Au) zone encountered there during 2022-2023 drilling, while upgrading inferred resources and testing for potential near surface extensions of the high-grade gold system to the south and west (Figures 1 to 5). Drilling at RPM will be complemented by ongoing metallurgical work and environmental surveys as outlined in this announcement along with studies as necessary to inform economic assessment of the discovery to gain a head start for a potential initial low capex smaller scale operation at the high-grade RPM deposit requiring less infrastructure for early cashflow and high margins to self-fund expansion plans.
Due to the speed, efficiency and lower costs of running the Company owned RC rig on labor hire only, when compared to diamond drilling, this drill program is designed to be conducted at a lower cost, while providing the necessary data density to meet our objectives of expanding and proving up a significant amount of the existing RPM resource into the Measured and Indicated categories to allow conversion into economic reserves for the upcoming FS.
The Company looks forward to announcing the assay results from the drill campaign as they come in to assess the significance of the observations in Figures 1-4.
