Nova Announces Strategic Investment in Adelong Gold

Melbourne, Australia, Sept. 09, 2025 (GLOBE NEWSWIRE) — Nova Minerals Limited (“Nova” or the “Company”) (NASDAQ: NVA) (ASX: NVA) (FRA: QM3) ) is pleased to announce a strategic cornerstone investment representing 7.8% of the ordinary shares in Adelong Gold Limited (ASX: ADG) (Adelong), a gold-antimony focused exploration and near-term production company with a diversified portfolio of high-grade projects across Australia and Brazil.

This investment forms part of Nova’s ongoing strategy to partner with undervalued, high-growth-stage resource companies with projects in proven mineralized districts that offer near-term production upside, exposure to high-impact exploration results, and long-term value creation through diversification.

Nova’s strong balance sheet enables it to make the Adelong investment, which we believe could offer significant upside potential, and which we do not expect to compromise the pace or scale of our ongoing development activities at its flagship Estelle Gold and Critical Minerals Project. The Estelle Project remains Nova’s primary focus, with the current drilling season nearing completion and a strong pipeline of near-term, value-driving catalysts anticipated, including drill assay results, surface exploration data, further metallurgical test work, and an updated Mineral Resource Estimate (MRE) expected to enhance both the scale and confidence of the existing multimillion-ounce gold resource.

In addition, Nova’s application for U.S. Department of Defence grants to potentially fast-track its antimony project continues to advance.

Nova CEO, Mr. Christopher Gerteisen commented: “Adelong represents a unique investment opportunity, combining near-term gold production potential with significant high-grade exploration upside and future antimony prospects. With drilling now underway at the high-priority Apollo and Lauriston prospects — strategically located near Agnico Eagle’s world-class Fosterville Mine — Adelong is ideally positioned to potentially leverage strong gold market conditions and multiple exploration catalysts. Lauriston’s historical production of approximately 233,000 ounces at an average grade of 20.7 g/t gold from shallow depths highlights the strength of the system, while recent drilling has delivered exceptional results, including 8m @ 104 g/t Au, with 2m @ 413 g/t Au from 95m⁽¹⁾.

With drilling success already demonstrated, first gold recently produced at Challenger, and we believe Adelong is poised for a transformational phase. Nova is excited to support this growth story with capital and strategic support, as we work together to potentially generate significant value for both companies’ shareholders.”
