ANCHORAGE, Alaska : Nova Minerals Ltd. (ASX: NVA, OTCQB: NVAAF) has identified a high-priority gold target at its Estelle Gold Project, following surface sampling results that confirmed high-grade mineralization west of the existing RPM deposit.
The discovery, located within the West Susitna Mineral District, highlights a significant expansion of the mineralized footprint at the project. Rock samples collected during the 2025 exploration season at the “RPM West” target yielded gold grades as high as 24.6 g/t. This development sets the stage for a targeted drilling campaign scheduled for 2026, as the company seeks to replicate the success of its flagship RPM deposit.
For investors, the timing is critical. Alaska’s Tintina Gold Belt: a province hosting some of the world’s largest gold systems: remains a focal point for Tier 1 discoveries. Nova Minerals is now positioning itself to prove that RPM is not an isolated occurrence, but part of a much larger, high-grade corridor.
The Numbers Behind the Discovery
The 2025 exploration program was not a cursory glance at the surface. It was a systematic, data-driven assault on the Estelle Project’s 35-kilometer mineralized trend.
The company covered 75 line kilometers and collected a massive dataset: 430 soil samples, 170 rock samples, and 26 stream sediment samples. The results were immediate. Approximately 2 to 3 kilometers west of the main RPM area, geologists discovered a quartz-sulfide vein within felsic intrusive rock that graded an astonishing 246 g/t Au.
That is not a typo.
While that peak assay represents a localized high-grade vein, the broader sampling at RPM West returned consistent results, including peak assays of 24.6 g/t Au. Three separate samples in the area exceeded 10 g/t Au. On the northern section of the main RPM ridge, the highest rock sample graded 11.7 g/t Au, further validating the northern extension of the mineralized system.
The geochemistry tells a compelling story. Nine soil samples along the northern RPM ridge showed gold concentrations significantly above background levels, with one reaching 1.6 g/t Au. In the world of soil sampling, those are loud numbers. They point to a buried system that is leaking gold to the surface.
Why RPM West Matters
The significance of RPM West lies in its proximity to the existing RPM resource. In mining, “near-mine exploration” is the lowest-risk, highest-reward strategy. If Nova can prove that the high-grade “pods” identified at RPM North and RPM South extend or repeat at RPM West, the project’s economics shift from robust to exceptional.
“The discovery of high-grade mineralization at RPM West is a potential game-changer for the 2026 season,” said an industry analyst familiar with the Tintina Belt. “They are seeing the same geological signatures: felsic intrusives and quartz-sulfide veins: that characterize the million-ounce deposits nearby. It’s a repeat of the pattern.”
This pattern recognition is vital. The Estelle Project already contains two multi-million-ounce gold resources. However, the market has been waiting for evidence that Nova can find more than just bulk-tonnage, low-grade ore. These high-grade surface hits provide that evidence.
The strategy is clear: define the high-grade targets now to maximize drill efficiency in 2026. This mirrors the trajectory of other successful Alaskan projects, such as Taseko’s Florence Copper, where systematic de-risking led to operational status.
Geological Context: The Tintina Gold Belt
To understand Nova’s potential, one must understand the neighborhood. The Tintina Gold Belt stretches from Alaska into the Yukon and houses giants like Donlin Creek and Fort Knox.
Nova’s Estelle Project sits on the same structural trend. The mineralization is typically associated with Reduced Intrusion-Related Gold Systems (RIRGS). These systems are known for their massive scale, but they can be tricky. The gold is often hosted in sheeted veins and stockworks within and around felsic intrusions.
What Nova has found at RPM West is the classic RIRGS “smoke.” The high-grade quartz-sulfide veins (like the 246 g/t Au outlier) suggest a high-energy mineralizing event. When you find these veins at the surface, you aren’t just looking at a single vein; you are looking at the plumbing system of a much larger body of mineralization.
The 2025 program successfully mapped these plumbing systems across 75 kilometers. By identifying these anomalies now, Nova is shortening the path to a resource upgrade.
The 2026 Inflection Point
The mining industry is currently grappling with a paradox. While gold prices hover near historic highs, capital for exploration remains selective. Investors are no longer interested in “blue sky” promises; they want high-grade targets and clear timelines.
Nova Minerals is leaning into this reality. The company has designated the RPM ridgeline as a high-priority drill target for 2026. The goal is simple: identify the next high-grade pod.
The clock is already ticking. Exploration in Alaska is dictated by the seasons, and the 2025 data has provided the roadmap for a high-impact 2026 campaign. This is not just about adding ounces; it’s about adding the right ounces: the ones that can be mined at lower costs and higher margins.
As we have seen with other strategic minerals projects in the U.S., such as the US Antimony injection to break the China-Russia grip, domestic supply chains and proven mineral reserves are becoming matters of national and economic security. While Nova is primarily a gold play, the Estelle project also contains critical minerals, adding another layer of strategic value to the district.
Strategic Infrastructure and District Development
One cannot discuss the Estelle Gold Project without mentioning the West Susitna Mineral District as a whole. The district is undergoing a transformation. The State of Alaska has been supportive of the West Susitna Access Road, a piece of infrastructure that would fundamentally change the cost structure for every project in the area.
For Nova, this infrastructure is the “missing middle.” It bridges the gap between a world-class discovery and a world-class mine. Similar to how Oklahoma is betting on refining for mineral sovereignty, Alaska is betting on infrastructure to unlock its mineral wealth.
With access comes lower operational hurdles. The ability to move heavy equipment and supplies by road rather than air could reduce exploration and development costs by 30% or more. This makes the high-grade hits at RPM West even more valuable, as the threshold for economic viability drops.
Market Outlook and Investor Strategy
Nova Minerals (ASX: NVA) has had a volatile run, typical of junior explorers in a high-interest-rate environment. However, the underlying asset continues to grow. The current market capitalization often fails to account for the sheer scale of the Estelle project, which remains one of the few independently owned, multi-million-ounce gold projects in a Tier 1 jurisdiction.
The 2026 drill program will be the ultimate test. If Nova hits high-grade mineralization at depth at RPM West, the “pod” theory will be confirmed. This would suggest that the Estelle project is not just a collection of deposits, but a continuous mineralized system with multiple high-grade centers.
Investors should watch for:
- Permitting updates: Any progress on the West Susitna Access Road.
- 2026 Drill Mobilization: Early indicators of the scale of the upcoming campaign.
- Geochemical follow-up: Further sampling results from the periphery of the 2025 program.
The Bottom Line
Nova Minerals has done the heavy lifting. The 2025 exploration program has provided the data necessary to de-risk the next phase of growth. With surface grades of up to 24.6 g/t Au and a monster 246 g/t Au vein in the vicinity, RPM West is no longer a “potential” target: it is the primary target.
The transition from 2025 discovery to 2026 drilling represents a pivotal moment for the company. In a market that is increasingly hungry for domestic gold production and high-grade discoveries, Nova Minerals is sitting on one of the most promising trends in the North American Arctic.
As the industry moves toward 2026, the focus will shift from “what is there” to “how big is it.” If the RPM West anomalies are any indication, the answer could be very big indeed.
