Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Filing Summary
Nova Minerals Corp said an engineering and processing-capacity assessment confirmed approximately 216,000 tonnes per annum of front-end crushing, grinding and concentration capacity at the Port MacKenzie, Alaska plant. Nova is advancing a Phase 1 refinery under a fully funded $43.4 million Department of War-supported project. The refinery is designed to produce up to approximately 600 tpa of refined antimony, with domestic production of military-grade antimony trisulphide targeted for 2027; standard Grade II antimony metal, greater than 99.65% purity, is an intermediate co-product.
Capacity modeling indicates potential refined antimony production of approximately 9,400 tpa at a 5% antimony feed grade and 20,000 tpa at a 10% grade, subject to feed grade, additional downstream refinery equipment and other operating requirements. Under those modeled scenarios, additional primary crushing, sorting or grinding equipment would not be required; expansion would principally require downstream refining capacity. The facility could also process feedstock from Nova’s Estelle Project and suitable third-party mineral sources.

Exhibit 99.1
Nova Minerals Confirms 216,000 tpa Processing Capacity, Advancing Alaska’s Critical Minerals Hub
Anchorage, Alaska, November 10, 2026 – Nova Minerals Corp (“Nova” or the “Company”) (NYSE American: NVA | ASX: NVA) is pleased to announce that an engineering and processing capacity assessment of its newly acquired processing plant, which is to be constructed at Port MacKenzie, Alaska, has confirmed front-end crushing, grinding and concentration capacity of approximately 216,000 tonnes per annum (tpa). This substantial processing capacity provides a scalable platform for future commercial antimony production, with capacity modelling indicating potential refined antimony production of up to approximately 20,000 tpa, subject to feed grade, additional downstream refinery equipment and other operating requirements.
The processing infrastructure provides a strong foundation for Nova’s strategy to establish a fully integrated U.S. domestic antimony and critical minerals processing and refining hub in Alaska, with the capability to produce both antimony metal and antimony trisulphide. The facility is also intended to support processing of feedstock from Nova’s Estelle Project and potentially suitable third-party mineral sources, creating opportunities to expand domestic processing capacity and strengthen U.S. critical minerals supply chains.
Highlights
| ● | 216,000 tpa processing capacity: Plant crushing, sorting, grinding and concentration infrastructure provides significant capacity for future commercial operations. | |
| ● | Two parallel grinding circuits: Two mill trains, each with approximately 108,000 tpa capacity, provide operational flexibility, staged expansion opportunities, and capacity for additional suitable mineral feedstocks. | |
| ● | Phase 1 pilot-scale refinery up to 600 tpa: Initial production of military-grade antimony trisulphide and >99.65% antimony metal is being advanced under the fully funded $43.4 million Department of War (DoW) supported project. | |
| ● | Significant full-scale commercial expansion potential: Capacity modelling indicates potential refined antimony production of approximately 9,400 – 20,000 tpa, with 5 – 10% Sb feed grade, subject to additional downstream refinery equipment and other operating requirements. | |
| ● | Multi-commodity processing opportunity: Plant infrastructure could also support processing of tungsten, gallium, bismuth, tellurium, arsenic, and other suitable critical mineral feedstocks. | |
| ● | Potential regional toll-processing hub: Port MacKenzie provides a strategic processing destination for Nova’s Estelle Project and potentially other third-party mineral producers. |
Nova Minerals CEO, Mr. Christopher Gerteisen, commented:
“The confirmation of 216,000 tonnes per annum of front-end processing capacity is a significant milestone for Nova and highlights the strategic value of the infrastructure we have secured at Port MacKenzie.
“While our initial $43.4 million Department of War supported project is focused on establishing production of up to 600 tonnes per annum of refined antimony, the processing infrastructure acquired provides a clear pathway to a substantially larger commercial operation, with additional downstream refining equipment representing the principal requirement for expansion.
“Importantly, this infrastructure also creates opportunities beyond antimony, with the potential to establish Port MacKenzie as a multi-commodity critical minerals processing and refining hub serving Nova’s Estelle Project and other mineral producers throughout Alaska and the broader region.
“Our vision is to develop strategically important domestic processing infrastructure that supports US critical minerals independence, strengthens secure domestic supply chains and positions Alaska as a major participant in the US critical minerals industry.”
216,000 tpa – A Significant Processing Infrastructure Advantage
The modern turnkey processing plant, previously owned and operated by Agnico-Eagle at the Hope Bay Gold Project, has been procured and delivered to Nova’s Port MacKenzie site. The plant incorporates crushing, grinding, gravity, flotation and leaching circuits, together with associated equipment and engineering plans. A Steinert ore sorter has also been separately procured.
The grinding circuit establishes overall processing capacity of approximately 216,000 tpa, comprising two parallel mill trains, each capable of processing approximately 108,000 tpa.
This substantial front-end capacity provides operational flexibility and the ability to progressively expand production without requiring replacement of the major existing processing infrastructure. It also provides a potential capital advantage compared with developing an entirely new processing facility.
Phase 1 Pilot-Scale 600 tpa Refinery – Foundation for Larger Commercial Expansion
Nova is currently advancing its Phase 1 refinery under the $43.4 million DoW supported project, targeting domestic production of military-grade antimony trisulphide in 2027.
Based on extensive metallurgical test-work, Nova has developed a hydrometallurgical flowsheet incorporating leaching, electrowinning, melting and sulphurization to produce military-grade antimony trisulphide, with standard Grade II antimony metal (greater than 99.65% purity) as an intermediate co-product.
The initial refinery is designed to produce up to approximately 600 tpa of refined antimony, with electrowinning capacity representing the principal production constraint. This deliberately staged, pilot-scale development reflects the scope of the DoW funded project and is not representative of the substantially larger processing capacity which will be available through the already acquired front-end plant.
Commercial Expansion - Potential Production of up to 20,000 tpa Refined Antimony
Following successful completion of Phase 1, Nova sees a clear pathway to substantially increasing commercial antimony production by leveraging the existing 216,000 tpa front-end processing infrastructure and installing additional downstream refinery equipment, principally electrowinning and melting capacity.
Depending on feed grade and assuming sufficient downstream refinery capacity, modelling indicates potential refined antimony production of approximately:
| ● | 9,400 tpa based on a 5% antimony feed grade; and | |
| ● | 20,000 tpa based on a 10% antimony feed grade. |
The capacity assessment indicates that additional primary crushing, sorting and grinding equipment would not be required under the modelled production scenarios. The principal expansion requirement would be additional downstream refining capacity.
These scenarios highlight the significant potential of the acquired infrastructure to support a much larger commercial antimony operation as Nova progresses beyond the initial Phase 1 project.
Beyond Antimony – Building America’s Critical Minerals Hub in Alaska
The 216,000 tpa processing platform also creates opportunities beyond antimony, with the potential to process suitable third-party ores and concentrates and evaluate additional critical mineral commodities, including tungsten, gallium, bismuth, tellurium, arsenic, and other strategic elements.
Nova sees the potential for Port MacKenzie to become a regional toll-processing destination, providing third-party mineral producers with access to established processing infrastructure while creating potential additional revenue streams for the Company.
Nova is actively engaged in collaborations with the University of Alaska Fairbanks CORE-CM, the National Science Foundation Critical Mineral Accelerator Engine in Alaska and other US Government programs. The Company is also pursuing additional funding opportunities, with applications submitted and under review, to support development of the Estelle Critical Minerals Project and Port MacKenzie Processing and Refining Hub.
