Nova Minerals (NASDAQ: NVA) outlines new Portage Pass gold anomaly near Korbel
Rhea-AI Filing Summary
Nova Minerals Limited reports new exploration results from its 2025 surface program at the Estelle Gold and Critical Minerals Project in Alaska, outlining a significant gold anomaly at Portage Pass about 2.5 km from the Korbel deposit. Rock assays returned up to 14.3 g/t gold, with 11 rock samples above 1.0 g/t and several above 4 g/t. Soil sampling defined 23 samples at or above 0.2 g/t gold, including 10 above 0.5 g/t with a peak of 1.8 g/t. The company plans a detailed soil grid and a potential induced polarization survey in 2026 to better define this target. Estelle hosts two multi-million-ounce gold resources across a 35 km trend, and Nova is also advancing a US$43.4 million U.S. Department of War–funded antimony project aimed at production in late 2026/2027.

Insights
Nova outlines a promising new gold anomaly near existing Estelle resources, but results remain early-stage exploration data.
The update highlights Portage Pass as a new gold target only 2.5 km from the established Korbel deposit within the Estelle project. Sampling produced strong rock grades up to 14.3 g/t gold and soil anomalies peaking at 1.8 g/t, over multi‑kilometre traverses, indicating a potentially sizable mineralized system.
These are surface assays without drilling, so continuity, thickness, and eventual resources are not yet defined. The planned 2026 soil grid and induced polarization survey should refine targets and determine where to drill. The company also notes a US$43.4 million award to support its antimony strategy, with production targeted for 2026/2027, which may help fund broader project advancement.

Exhibit 99.1
Nova Announces a Significant New Gold Anomaly Developing at Portage Pass
Anchorage Alaska, April 14, 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 Portage Pass area of its flagship Estelle Gold and Critical Minerals Project, located within Alaska’s prolific Tintina Gold Belt has identified a new broad zone of gold mineralization 2.5km from Korbel.
Highlights
| ● | Potentially significant new gold anomaly defined at Portage Pass from field observations and 2025 surface assays (Figure 3). |
| ● | Geochemical signature comparable to the multi-million ounce Korbel gold deposit across the ridgeline to the north, with mineralization appearing more consistent and higher grade. |
| ● | Strong potential for valley-scale extension analogous to the exploration pathway that led to the Korbel discovery. |
| ● | Anomaly supported by seven rock samples grading >2 g/t Au including a high of 14.3 g/t Au (Table 1), and 10 soil samples grading >0.5 g/t Au with a peak of 1.8 g/t Au (Table 2) discovered along the ridgelines above the Portage Creek valley floor. |
| ● | 2026 soil sampling program planned, with a follow-up IP geophysical survey to be undertaken in line with the exploration approach that led to the Korbel discovery (Figure 3). |
Nova General Manager and Geologist, Mr Hans Hoffman, commented:
“The 2025 surface sampling at Portage Pass has outlined a broad gold anomaly just over the ridge from the established Korbel deposit. The proximity to existing resources and proposed infrastructure makes Portage Pass particularly compelling. These early results reinforce our belief that the greater Estelle district continues to deliver new opportunities with real upside potential.”
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. |
| ● | Assay results from recent rock and soil sampling have identified a significant new gold anomaly at Portage Pass, as detailed in this announcement. |
All results from 2025 soil and rock sampling across the project district have now been reported.

Portage Pass
139 soil samples and 68 rock samples were collected along traverses in the central portion of the claim block between Korbel and Stoney/West Wing. A moderate grade anomaly is developing in the headwaters of Portage Creek with 23 soil samples greater or equal to 0.2 g/t Au, including 10 soil samples greater or equal to 0.5 g/t Au. 11 rock samples primarily focused on the Estelle pluton granodiorite are greater than 1.0 g/t Au, including 5 greater or equal to 4 g/t Au and a high of 14.3 g/t Au.
The anomalies were identified across two separate traverses of approximately 3.5km and 2.8km, highlighting the potential for this moderate-grade mineralization to extend into the valley in a manner comparable to the Korbel deposit, located immediately north across the ridge. Notably, mineralization identified in talus fines and base of outcrop samples above the Portage Pass valley appears more consistent and of slightly higher grade than that observed at Korbel.
A detailed soil sampling grid is planned across the valley in 2026. Subject to the results, a ground-based induced polarization (IP) geophysical survey will be undertaken, following a similar exploration pathway to that which led to the discovery at Korbel.
While stronger geochemical anomalies are present elsewhere at Estelle, Portage Pass represents a compelling target given its proximity to Korbel and the associated proposed infrastructure.
