Nova Minerals Commences Antimony-Gold Drilling at its Stibium Prospect

Anchorage Alaska, June 11, 2025 (GLOBE NEWSWIRE) -- Nova Minerals Limited (“Nova” or the “Company”) (NASDAQ: NVA) (ASX: NVA) (FRA: QM3) ) is pleased to advise that drilling has commenced at its highly prospective Stibium prospect targeting both gold and antimony mineralization. The first diamond drill rig is now operational, with a second diamond rig and the Company-owned RC rig currently being mobilized and scheduled to begin drilling later in June.

Nova’s application for U.S. Department of Defense funding to potentially fast track antimony from mining to refining continues to progress.

Highlights

• A maiden 3,000m diamond drill program is now underway at the Stibium prospect located in close proximity to Nova’s Whiskey Bravo camp and the bulk tonnage Korbel gold deposit (Figures 1 and 2).

• The first drill hole is designed to test a potential high-grade gold-antimony zone, delineated through extensive surface sampling (Figures 3 and 4).

• Drilling at the Stibium prospect is focused on delivering a maiden Mineral Resource Estimate (MRE) for both gold and antimony at this site. Surface sampling has confirmed a significant mineralised footprint, approximately 800 metres long and 400 metres wide, with standout results including: (ASX Announcement: 14 January 2025, and Figures 3 and 4):

• • 12 rock samples > 30% Sb with a high of 60.5% Sb

  • 10 soil samples > 0.1% Sb with a high of 2.8% Sb

  • 16 rock samples > 5 g/t Au with a high of 141 g/t Au

  • 35 soil samples > 1 g/t Au with a high of 25.6 g/t Au

• A second diamond drill rig, along with the Company-owned reverse circulation (RC) rig, is currently being mobilized and is scheduled to commence drilling later in June.

• Nova’s application for potential U.S. Department of Defense (DoD) funding to fast track its antimony assets from mining to refining has continued to progress and if successful, upon receipt of such grant funds the Company intends to:

2. Add further diamond drill rigs to this year’s exploration program

3. Develop a state-of-the-art antimony metallurgical processing hub at Port Mackenzie, Alaska. The Company has already submitted applications and is in discussions with the Port Mackenzie Authority to secure a long-term land lease, with the potential to expand the site footprint.

4. Engage with potential antimony off take partners.

5. Employ a world-leading antimony refining expert. Discussions in this regard have already commenced.
