Nova Minerals Discovers Further High-Grade Gold at its Wombat Prospect up to 360 g/t Au on its Estelle Gold and Critical Minerals Project, in Alaska
Nova Minerals (NVA) has announced significant high-grade gold and gallium discoveries at its Wombat Prospect within the Estelle Gold and Critical Minerals Project in Alaska. The 2024 exploration revealed 7 out of 17 rock samples exceeding 2 g/t Au, with exceptional grades of 360 g/t Au (second-highest gold sample at Estelle) and 93.2 g/t Au.
The exploration also identified high-grade gallium, with 10 samples exceeding 30 ppm Ga and a peak of 74.5 ppm Ga. This is particularly significant as gallium is a critical mineral following China's export ban. The Wombat prospect shows a gold anomaly with up to a 1km long strike length, featuring thick quartz-arsenopyrite veins up to 4m wide.
At the Stoney prospect, sampling revealed combined gold, silver, copper, and antimony mineralization, with the best sample yielding 6.1 g/t Au, 124 ppm Ag, 2.4% Cu, and 340 ppm Sb.

Insights
The latest exploration results from Nova Minerals' Wombat prospect represent a remarkable discovery that significantly enhances the potential of their Estelle Gold project. The headline grade of
The discovery's value is amplified by three key factors:
- The consistent high-grade nature of the findings, with 7 out of 17 samples exceeding 2 g/t Au
- The significant strike length of 1km, suggesting substantial resource potential
- The presence of high-grade gallium, with 10 samples exceeding 30 ppm, reaching up to 74.5 ppm
The gallium discovery is particularly timely given China's recent export ban on this critical mineral. Gallium is essential for semiconductors, LEDs and defense applications, making domestic sources increasingly valuable. The U.S. Department of Defense's interest in securing domestic supply chains adds strategic importance to this finding.
The project's location in Alaska's Tintina Gold Belt is another significant advantage. This region hosts several world-class gold deposits and the infrastructure and regulatory environment in Alaska are favorable for mining development.
Looking ahead, these results strongly justify follow-up drill testing. The combination of exceptional gold grades, significant strike length and critical mineral content positions this discovery as a potentially significant contributor to Nova's resource base. The systematic exploration approach, with over 500 soil samples and 225 rock samples collected, demonstrates a thorough evaluation of the property's potential.
Anchorage Alaska, Jan. 23, 2025 (GLOBE NEWSWIRE) -- Nova Minerals Limited (“Nova” or the “Company”) (NASDAQ: NVA) (ASX: NVA) (FRA: QM3) ) is pleased to announce additional high-grade gold and gallium surface sample assay results from its 2024 exploration season with 7 rock samples grading > 2 g/t Au, including a high of 360 g/t Au which is the 2nd highest gold sample found at Estelle to date, and 10 multi-element samples from 2023 and 2024 grading > 30 ppm Ga (gallium), with a high of 74.5 ppm Ga from the Wombat prospect at the Company’s over 500km2 flagship Estelle Gold and Critical Minerals Project located in the Tintina Gold Belt in Alaska.
Highlights
- 2024 follow-up sampling of the thick, up to 4m, high-grade quartz-arsenopyrite veins discovered at Wombat in 2023 further confirms the presence of a gold anomaly with up to a 1km long strike length (Table 1 and Figure 3).
- 2024 sampling reveals 7 out of 17 rock samples greater than 2 g/t Au at Wombat, including 360 g/t Au and 93.2 g/t Au (Table 1).
- Previously announced results from Wombat in 2023 (ASX Announcement: 29 January 2024) included ten samples greater than 2 g/t Au, with a high in a reclassified sample of 298 g/t Au (Table 1).
- Multi-element analysis of samples taken from Wombat in 2023 and 2024 also revealed high-grade gallium, with 10 samples greater than 30 ppm ga and a high of 74.5 ppm Ga. Gallium is another critical mineral for which the U.S. Department of Defense is seeking to secure a domestic supply chain for since China recently banned all exports (Table 2 and Figure 4).
- Gold, silver, copper, and antimony anomaly hosted in Stoney Vein with massive exposure with 10m width, 300m vertical relief, and 1km strike length (Table 3 and Figures 5 to 9).
- Final results being processed for surficial mapping and sampling at RPM.
Nova Head of Exploration, Mr Hans Hoffman commented: “Wombat and Stoney are early-stage prospects in the heart of the Estelle claim block. The consistency of vein-hosted mineralization at both of these prospects will warrant drill testing down the road as we continue to unlock the potential of the Estelle Gold and Critical Minerals project.”
2024 Exploration Mapping and Sampling Program Results
During the 2024 field season Nova’s Head of Exploration, Mr. Hans Hoffman, continued the surface exploration mapping and sampling program across the Estelle claim block with a particular focus on following up results at prospects identified in the 2023 season. 511 soil samples, 225 rock samples, and approximately 5 tons of bulk sample material were collected across the property (Figure 3).
As a result of that program, and reported to date:
- Assay results from soil and rock chip samples from the Styx prospect identified high-grade antimony (Sb) and gold in outcrop, with grades up to
54.1% Sb and 9.8 g/t Au (ASX Announcement: 22 November 2023). - Assay results from soil and rock chip samples collected from the Muddy Creek prospect, with a high of 128.5 g/t Au, have extended the high-grade gold mineralization zone by a further 400m to 800m in length now. Muddy Creek is considered to be one of the most impressive gold anomalies on the claim block to date (ASX Announcement: 27 November 2024).
- Assay results for antimony from rock samples collected at the Stibium prospect have identified an 800m long by 400m wide antimony rich zone with results of up to
56.7% Sb and 11 samples grading >30% Sb (ASX Announcement: 5 December 2024). - Assay results for gold from rock samples collected at the Stibium prospect show the previously identified 800m long by 400m wide zone is rich in both gold and antimony, with gold results of up to 141 g/t Au and seven samples greater than 20 g/t Au (ASX Announcement: 11 December 2024).
- Assay results for gold and antimony from soil samples collected at the Stibium prospect have identified high-grade resource targets within the previously identified 800m long by 400m wide zone (ASX Announcement: January 13, 2025), and
Assay results for gold and multi-elements including silver, copper, gallium, and antimony from samples collected at both Wombat and Stoney have now been received, and reported in this announcement.
Final results from the soil and rock chip samples taken from the wider RPM area in 2024 will be reported shortly.
A summary of the 2024 sampling program is shown below in Figure1.

Wombat Surface Sampling
Field crews conducted another surface sampling program over the newly discovered Wombat area in 2024. A total of 17 rock samples were collected, 7 of which were greater than 2 g/t Au, with exceptional grades of 360 g/t and 93.2 g/t Au recorded. The exceptionally high-grade samples located in the center part of Figure 3 below are from a weathered quartz-arsenopyrite vein.
A lab discrepancy in a rock sample previously reported as being from RPM in 2023, was actually found to have come from the Wombat prospect, and graded 298 g/t Au, when re-analyzed in 2024.
Table 1 below provides a summary of the top ten gold rock sample results found at Wombat over the 2023 and 2024 exploration programs. Samples from 2023 were previously reported in the ASX Announcement dated 29 January 2024, with the exception of sample number E408592 which has been corrected following the lab discrepancy noted above.

In addition to the high-grade gold results as shown above, the Wombat prospect also contains 10 of the 15 highest gallium values identified across the Estelle project. Gallium has also been listed as a critical mineral by the USGS, and it is used in electronic circuits, semiconductors, LEDs, and radar systems. The U.S. Department of Defense is also seeking to secure a domestic gallium supply chain since China recently banned all exports of this critical mineral. In granitic rocks, concentrations of gallium greater than 30 ppm can be considered high-grade.
Table 2 below provides a summary of the top ten gallium (ga) rock sample results found at Wombat over the 2023 and 2024 exploration programs. Gallium has not previously been reported in exploration results and accordingly is being reported for the first time in this announcement.

Stoney Surface Sampling
In 2024 one day was spent at Stoney to attempt to expand the previous geochemical coverage of the vein main vein occurrence. Accessing the vein directly is difficult due to terrain and ice, however a 250m traverse was conducted where samples of the vein were attainable below the base of outcrop. One prominent chute was used to access the vein directly. Gold distribution was a bit variable with five samples greater than 1 g/t Au, however most samples had additional silver, copper, and antimony components. Table 3 below provides the top 15 samples collected in 2024 with respect to cumulative gold, silver, copper, and antimony grades. These samples are also presented in Figures 6 through 9. Additional metallurgical work is required to report gold equivalent grades.
