Nova Minerals Limited disclosed that its 2025 RPM Valley drilling program at the Estelle Gold and Critical Minerals Project produced a record‑grade intercept of 0.5 m at 364 g/t Au, the highest‑grade result ever reported for the project. The program also returned a 65 m intercept at 3.6 g/t Au from hole RPM‑081 and a 33 m intercept at 0.3 g/t Au from glacial till drilling, underscoring the breadth of the mineralized system.
The 364 g/t intercept demonstrates that the Estelle Project contains discrete high‑grade zones within a broader, open‑ended gold system. Such high‑grade targets are critical for improving the economics of a large district‑scale asset, as they can be mined at lower cost and provide a strong foundation for a first‑production plan. The intercept also signals that the resource expansion potential is greater than previously modeled, which will feed into the company’s upcoming pre‑feasibility studies.
Management confirmed that the new data confirm the continuity of mineralization at depth and in multiple directions, reinforcing the company’s confidence that the system remains wide open. This continuity is a key driver for the planned resource expansion and supports the company’s strategy to advance toward first production, as it reduces exploration risk and accelerates the path to a commercial mine.
The Estelle Project is a district‑scale asset in Alaska’s Tintina Gold Belt, currently holding a JORC‑compliant gold resource estimate of 9.9 million ounces. In addition to gold, the project is a critical‑minerals asset with significant antimony potential, adding strategic value amid global demand for defense‑grade materials. The glacial till results suggest the presence of bulk‑mineable oxide material that could be processed via heap leach, offering a lower‑cost option for a portion of the deposit.
CEO Christopher Gerteisen highlighted that the high‑grade intercepts “represent a significant advancement for RPM Valley and further validate the scale and quality of the gold system identified to date.” He added that the discovery confirms discrete high‑grade zones within a broader system that remains wide open in multiple directions and at depth, underscoring the company’s confidence in the project’s long‑term viability and its strategy to move toward production.
The company’s 30‑plus‑year experience in leading resource projects, combined with the Estelle Project’s scale and dual‑resource potential, positions Nova Minerals to capitalize on both gold and critical‑minerals markets. The new drilling results will inform the next phase of pre‑feasibility studies, helping to refine cost estimates, mine design, and production plans for a potential first‑production milestone.
