High-grade RPM gold finds boost Nova Minerals (NASDAQ: NVA)
Rhea-AI Filing Summary
Nova Minerals Limited reports new high-grade gold results from its 2025 surface sampling at the RPM regional and ridgeline area within the Estelle Gold and Critical Minerals Project in Alaska. Rock samples returned grades up to 24.6 g/t Au and soils up to 5.5 g/t Au, outlining new anomalies west of RPM and along the northern RPM ridgeline.
These results build on earlier RPM reconnaissance and have led the company to rank the RPM ridgeline as a high-priority drill target for 2026. Nova is advancing Estelle as a large undeveloped gold project while also progressing a US$43.4 million U.S. Department of War–funded antimony supply initiative targeted for late 2026/2027.

Nova Announces Further High-Grade Gold Discovered at RPM
Anchorage Alaska, March 9, 2026 - Nova Minerals Limited (“Nova” or the “Company”) (NASDAQ: NVA) (ASX: NVA) (FRA: QM3) ) is pleased to announce assay results from its 2025 surface sampling program in the RPM regional and ridgeline area of the Company’s flagship Estelle Gold and Critical Minerals Project, located in the prolific Tintina Gold Belt in Alaska..
Highlights
| ● | Field observations and 2025 surface assays have identified new gold anomalies emerging to the west of RPM and along the northern end of the main RPM ridgeline (Figures 4 to 6). |
| ● | Anomaly highlighted by: |
| ○ | Three rock samples grading >10 g/t Au including a high of 24.6 g/t Au (Table 1), and three soil samples grading >1 g/t Au with a peak of 5.5 g/t Au (Table 2). |
| ● | These results build on earlier surface reconnaissance along the RPM ridge line, which previously returned 20 rock samples > 1.0 g/t Au, with a high of 52.3 g/t Au, and 11 soil samples > 0.5 g/t Au, with a high of 4.8 g/t Au (ASX Announcement: 3 February 2025). |
| ● | The RPM ridgeline is slated as a high-priority drill target for 2026 as the Company aims to identify the next high-grade pod similar to RPM North. |
Nova General Manager and Geologist, Mr Hans Hoffman, commented:
“Integrated geological, geochemical, and geophysical data, including initial interpretations from drone magnetometry 3D inversion processing all support a compelling drill target at the northern extension of the RPM ridge. Surface sampling has returned multi-gram gold assays from stockwork quartz veining in both hornfels and intrusive host rocks, with magnetic signatures along the ridgeline showing strong analogies to the main RPM deposit. Drill testing of these anomalies is a high priority for our 2026 program, and given its strategic location along access routes to RPM, any success here has the potential to deliver substantial upside to the Estelle Project.
“It’s too early to say what we have found a couple of kilometres to the west, but with grades up to 24.6 g/t Au, we will definitely be back in 2026 to expand on this anomaly.”
2025 Estelle Surficial Reconnaissance Program
During the 2025 field season, Nova’s geologist team, led by General Manager and geologist Mr Hans Hoffman, undertook an extensive surface exploration mapping and sampling program across three main areas of the Estelle Project comprised of over 30 traverses covering 75-line kilometers, 430 soil samples, 170 rock samples, and 26 stream sediment samples (Figure 1).
As a result of that program and reported to date:
| ● | Assay results from recent rock and soil sampling have outlined a newly developing large-scale gold-copper system at West Wing (ASX Announcement: 2 March 2026). |
| ● | Surface results from the RPM regional and ridgeline areas, including high-grade RPM-style gold assays of up to 24.6 g/t Au, have identified new drill targets at RPM, as outlined in this announcement. |
Further results from 2025 soil and rock sampling across the project district will be reported by area as they are received and processed in the coming weeks.

RPM Regional and Ridgeline
Additional sampling was conducted at the northern end of the main RPM ridge as well as along spur ridges 2-3km west of there. At the northern end of the main RPM Ridge, nine soil samples were greater than 0.2 g/t Au, including five greater than 0.4 g/t Au, and a high of 1.6 g/t Au. At this same location, four rock samples were greater than 1.0 g/t Au with a high of 11.7 g/t Au (Figure 3). These samples were collected primarily in granodiorite which was discovered in the creek drainage below the hornfelsed ridges above.
Two to three kilometers to the west a season high 24.6 g/t Au quartz-sulfide vein in felsic intrusive (Figure 3) was discovered along a spur ridge as well as a 14.6 g/t Au rock sample of sedimentary rock in a drainage just below there. No felsic intrusive had been previously noted in this region. Five soil samples collected in the vicinity were greater than 0.3 g/t Au with high of 1.0 g/t Au. Sampling in this area is relatively sparse and warrants follow-up in 2026.
