Nova Uncovers Gold Anomaly Near 8.65Moz Korbel Resource

Why It Matters

If the anomaly proves extensible, Estelle’s resource base could grow beyond its current 9.9 Moz, boosting Nova’s valuation and supporting its starter‑mine plan at RPM. The find also heightens the strategic relevance of Alaska’s Tintina Belt for U.S. critical mineral supply.

Key Takeaways

• Portage Pass anomaly lies 2.5 km from 8.65 Moz Korbel deposit
• Seven rock samples exceed 2 g/t Au, peak 14.3 g/t
• Ten soil samples grade over 0.5 g/t Au, indicating broad mineralisation
• Nova plans follow‑up soil program and IP survey to map extension
• Anomaly could add valley‑scale resources, raising Estelle’s 9.9 Moz base

Pulse Analysis

The Estelle district in Alaska’s Tintina Gold Belt has long been a focal point for large‑scale gold exploration, anchored by Nova Minerals’ 8.65 Moz Korbel deposit. The belt’s prolific geology, which hosts more than 220 Moz of documented gold, makes any nearby discovery a potential game‑changer for the company’s portfolio and for investors tracking frontier assets. Nova’s recent surface program, covering 75 km of traverses and over 400 soil samples, underscores its systematic approach to expanding the resource footprint.

At the newly identified Portage Pass prospect, seven rock samples surpassed 2 g/t gold, with a standout 14.3 g/t assay, while ten soil samples recorded grades above 0.5 g/t. The geochemical fingerprint closely matches that of Korbel, suggesting a contiguous mineralised system rather than an isolated pocket. Nova plans a second round of intensive soil sampling and an induced‑polarisation (IP) survey, mirroring the methodology that previously unlocked Korbel’s scale. If the follow‑up work confirms continuity, the anomaly could add a valley‑scale extension, potentially lifting the overall Estelle resource well beyond the current 9.9 Moz combined Korbel and RPM deposits.

Beyond gold, Nova’s broader strategy includes a U.S. $43.4 million grant to develop domestic antimony production, positioning the company at the intersection of precious metals and critical minerals policy. A larger Estelle resource would not only improve the economics of the planned RPM starter mine but also provide a domestic supply chain for antimony, a metal essential for flame‑retardants and aerospace alloys. The convergence of a new gold anomaly, ongoing feasibility studies, and government‑backed antimony funding amplifies Nova’s growth narrative and could attract both equity capital and strategic partnerships as the U.S. seeks to secure its mineral supply chain.
