Exhibit 99.1

Nova

Minerals Announces Korbel Floatation Test-work Produces High-Grade Gold Concentrate up to 26.7 g/t Au with Consistent Recoveries Exceeding

95%

Anchorage,

Alaska, June 29, 2026 - Nova Minerals Corp (“Nova Minerals” or the “Company”) (NYSE American: NVA | ASX:

NVA) is pleased to report results from bench-scale rougher flotation testing on low-grade Korbel ore, undertaken within a broader Feasibility

Study (FS) level metallurgical test-work program. Flotation of low-grade Korbel ore at a coarser-than-conventional grind size has the

potential to materially reduce both capital and operating costs while maintaining strong gold recovery.

Highlights

●

>95%

Gold Recovery: Low-grade Korbel ore (0.39–0.42 g/t Au) delivered a strong flotation response at 250 µm or finer,

producing a low-mass pull of only 2-3% (meaning a 97-98% reduction in the volume going to downstream processing), and a high-grade

concentrate of 14.7–26.7 g/t Au (Table 1).

●

Significant

Potential FS Value Upside: Application of coarse particle flotation to the bulk tonnage S-K 1300 compliant pit constrained 425

Mt @ 0.3 g/t Au (4.05 Moz Au) Korbel resource (Table 4) is expected to enhance Estelle’s FS outcomes by upgrading low-grade

ore, reducing processing intensity, lowering energy use, improving gold recovery, and simplifying the flowsheet (Figure 2) by potentially

eliminating ore sorting and heap leach requirements and allowing a significantly smaller Carbon-in-Leach (CIL) plant.

●

Ongoing

PFS Optimization: Korbel CIL test-work and further coarse particle flotation studies are underway to refine the flowsheet, confirm

high gold recovery and gangue rejection, and optimize plant design, scale, configuration, and overall project economics.

Nova

Minerals CEO, Mr. Christopher Gerteisen, commented:

“As

part of our ongoing Feasibility Study optimization work, these results represent a major breakthrough in our metallurgical test program.

The demonstration that Korbel ore is highly amenable to coarse particle flotation, producing a very high-grade concentrate representing

only 2-3% of the total mass while achieving gold recoveries in excess of 90%, has the potential to be a game changer for the project.

The

successful application of coarse particle HydroFloat technology to our process flowsheet has the potential to deliver substantial reductions

in processing and capital costs, while simplifying downstream operations. These improvements could significantly enhance the project’s

overall economics and increase our ability to profitably recover gold from lower-grade material across the bulk-tonnage Korbel deposit.

Metallurgical

test work is continuing to evaluate even coarser particle sizes, which could further improve the project’s processing cost profile

and strengthen our strategy of maximizing gold production and resource conversion over the life of the mine.”

Korbel

Flotation Metallurgical Test-work

The

test-work was undertaken on a composite sample generated from diamond drill core from the Korbel Main deposit, representing predominantly

fresh sulfide intrusive-hosted ore from an intrusion-related gold system. The sample material was selected from drill holes KBDH-005,

KBDH-011 and KBDH-025 over the intervals summarized in Table 2, with the results outlined in Table 1.
