Exhibit 99.1

Change to ADS Ratio and Stock Distribution

Melbourne, Australia, October 15, 2025 - Nova Minerals Limited (“Nova” or the “Company”) (NASDAQ: NVA, NVAWW) (ASX: NVA) (FRA: QM3) announces a ratio change to its sponsored American Depositary Receipt (“ADR”) program with The Bank of New York Mellon.

This corporate action, which is a 5 for 1 forward split for the purposes of the NASDAQ listing, will have the effect of increasing the number of American Depositary Shares (“ADSs”) on issue. It has no effect on the number of underlying shares on issue or the nominal value of the ordinary shares.

The former ratio of sixty (60) ordinary shares to one (1) ADS has been changed to twelve (12) ordinary shares per one (1) ADS effective on October 28, 2025. There will be no change to the underlying ordinary shares.

The first day of trading under the new ratio is expected to be October 29, 2025.

To effect this change, ADR holders will receive four additional ADSs for every one (1) ADS held as of October 27. 2025, the ADR record date. Existing ADSs will continue to be valid and will not have to be exchanged for new ADSs. In connection with this change, the register held by The Bank of New York Mellon (BNY) will be closed for issuances and cancellations from the close of business on October 24, 2025 and BNY anticipates the registrar will reopen on October 30, 2025 for all issuance and cancellation transactions.

The Board has undertaken the forward split to better align the company’s share price with industry peers and enhance liquidity, offering broader access to investors amid strong interest in Nova’s gold and antimony assets as the Company continues to advance toward production.

In addition, the Company’s public warrants with the trading symbol “NVAWW” (the “Warrants”), were amended in accordance with the terms of the Warrant Agreement and the Definitive Certificate, whereby if the Company at any time while the Warrants are outstanding, enters into a forward stock split, an adjustment is made to the exercise price and the proportion of ADSs issued upon exercise of your Warrant in accordance with Section 4 of the Warrant Agreement and Section 3 of the Definitive Certificate. As such, upon the consummation of the change to ADS ratio and forward stock split, the exercise price of the Warrants shall be decreased from $7.266 per ADS to $1.4532 per ADS and the proportion of ADSs issued upon exercise of each Warrant will be proportionally adjusted from one Warrant for one ADS to one Warrant for five ADSs such that the aggregate Exercise Price of each Warrant shall remain unchanged. Similar adjustments will be made the Company’s private warrants.
