Highlights:
- Nova Minerals (ASX:NVA) is advancing its US grant applications for drilling at the high-grade Stibium gold-antimony prospect in Alaska, with results showing impressive soil and rock chip samples.
- The gold price remains near all-time highs, and antimony prices have surged, presenting a significant economic opportunity for the Estelle Project, particularly with US demand for critical minerals rising.
- Nova is preparing to begin resource drilling in 2025, aiming to establish a gold-antimony resource and potentially become one of the first US-based antimony producers.
Nova Minerals Ltd (ASX:NVA) , (NASDAQ:NVA) is advancing its exploration efforts at the Estelle Project in Alaska, focusing on the Stibium prospect, which has revealed an extensive and high-grade gold and antimony zone. This development comes amid a favorable economic backdrop, with gold prices hovering near record highs at US$2,717 per ounce and antimony prices surging from US$17,240 per tonne in 2023 to US$33,367 by October 2024. The significant rise in antimony prices has been driven by China's export restrictions on the mineral, making it even more valuable and enhancing the economic potential of Stibium.
The Stibium prospect now boasts a well-defined, high-grade gold and antimony target, ready for resource drilling. Nova's CEO, Christopher Gerteisen, emphasized the company's commitment to advancing this opportunity, particularly through seeking US Government grant funding to accelerate the project. The company is gearing up for 2025 field activities, including drilling at Stibium and the nearby RPM zone, positioning the Estelle Gold and Critical Minerals Project at a crucial moment, with strong commodity prices and the strategic importance of antimony.
Nova's exploration work has outlined an extensive mineralized zone at Stibium, based on results from 180 soil samples. High-grade gold is considered to be above 1 g/t, and over 35 soil samples returned gold grades above this threshold, with one sample even reaching 35.6 g/t gold. Additionally, 10 soil samples showed antimony concentrations above 0.1%, with some samples reaching up to 2.8% antimony. This solid groundwork has provided a clear picture of the potential of Stibium and supports the company's plan for further exploration and resource drilling.
In addition to soil sampling, Nova has collected over 200 rock chip samples, with the best results including gold grades as high as 141 g/t, 64.7 g/t, and 62.3 g/t. Antimony results have been equally impressive, with grades of 60.5%, 56.7%, and 55.7%, signaling the prospect's significant potential. Stibium has been defined over an 800-metre-long by 400-metre-wide zone, hosted in quartz diorite intrusive rocks and hornfels sedimentary rock. The zone remains open for further exploration, with potential extensions yet to be fully explored.
The company’s exploration team, led by Hans Hoffman, head of exploration, has noted the impressive gold and antimony anomaly at Stibium, which is visible in the final soil results. A heat map clearly shows the extent of the mineralized zone, and the team is focused on drilling identified high-grade stibnite veins, gold-bearing quartz veins, and mineralized hydrothermal breccia. The location of the ridge at Stibium is favorable for easy access, with minimal drill pad construction required and easier access to water due to its lower altitude compared to other Estelle prospects.
Nova is also moving forward with its grant applications to the US Department of Defense (DoD) as part of its membership in the Defense Industrial Base Consortium (DIBC). This step is vital because antimony is a critical mineral used in defense applications such as infrared sensors, semiconductors, night vision goggles, and munitions production. With both the US and the European Union fully reliant on imports of antimony, Nova is positioning itself to meet the growing demand for this essential resource. Following China's export restrictions on antimony, which accounted for 48% of global production in 2023, the mineral’s supply has been constrained, increasing the strategic importance of projects like Stibium.
Nova aims to bring Stibium into production as one of the first US-based antimony mines, tapping directly into the domestic demand for this critical mineral. The company's strategic location, strong exploration results, and the rising value of antimony put it in a prime position to capitalize on the growing demand for both gold and antimony. As Nova progresses with its drilling and grant applications, it remains focused on advancing the Estelle Gold and Critical Minerals Project and securing its place in the global minerals market.
