Exhibit 99.1

Amendment to the Scheme Implementation Deed for US Redomiciliation

Amendment to the Scheme Implementation Deed

Nova Minerals Limited (Nova or the Company) (ASX: NVA, NASDAQ: NVA, FSE: QM3) refers to its announcement dated 3 March 2026 regarding its entry into a Scheme Implementation Deed (SID) with Nova Minerals Corp (US Holdco) for the purpose of effecting the Company’s proposed redomiciliation to the United States.

On 31 March 2026, the Company executed a deed of amendment to the SID (Amendment Deed) which restates the consideration being offered for Nova’s Nasdaq listed warrants (Nova Listed Warrants). Originally, the SID provided that the holders of Nova Listed Warrants would receive US Holdco warrants to be listed on the NYSE (US Holdco Warrants) based on a ratio of 1 US Holdco Warrant for every 1 Nova Listed Warrant. Following discussions with the listing officers of the NYSE, Nova and US Holdco have agreed to increase the ratio to 3 US Holdco Warrants for every 1 Nova Listed Warrant held on the scheme record date. The ratio for the warrants exchange has been increased to satisfy the listing requirements of the NYSE regarding the listing of the US Holdco Warrants.

Security holders are not required to take any actions at this time.

The Amendment Deed is enclosed.

This announcement has been authorised for release by the Board of Nova Minerals Limited.
