NovaAnnounces a Significant New Gold Anomaly Developing at Portage Pass

---

AnchorageAlaska, 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<br> significant new gold anomaly defined at Portage Pass from field observations and 2025 surface<br> assays (Figure 3).
●	Geochemical<br> signature comparable to the multi-million ounce Korbel gold deposit across the ridgeline<br> to the north, with mineralization appearing more consistent and higher grade.
●	Strong<br> potential for valley-scale extension analogous to the exploration pathway that led to the<br> Korbel discovery.
●	Anomaly<br> supported by seven rock samples grading >2 g/t Au including a high of 14.3 g/t Au (Table<br> 1), and 10 soil samples grading >0.5 g/t Au with a peak of 1.8 g/t Au (Table 2) discovered<br> along the ridgelines above the Portage Creek valley floor.
●	2026<br> soil sampling program planned, with a follow-up IP geophysical survey to be undertaken in<br> line with the exploration approach that led to the Korbel discovery (Figure 3).

NovaGeneral Manager and Geologist, Mr Hans Hoffman, commented:

“The2025 surface sampling at Portage Pass has outlined a broad gold anomaly just over the ridge from the established Korbel deposit. Theproximity to existing resources and proposed infrastructure makes Portage Pass particularly compelling. These early results reinforceour belief that the greater Estelle district continues to deliver new opportunities with real upside potential.”

2025Estelle 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<br> results from recent rock and soil sampling have outlined a newly developing large-scale gold-copper<br> system at West Wing (ASX Announcement: 2 March 2026).
●	Surface results<br> 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<br> drill targets at RPM, as outlined in this announcement.
●	Assay results<br> 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.
