The assay results for the first eight holes have confirmed that the mineralisation is consistent with the geological model and identified new broad low grades containing local higher grade intervals at very shallow depths. The current program has been extended beyond the original plan of 3,250m to cover a greater strike length and ensure continuity of the highly prospective areas within the tertiary structure. Mr Romain is on site where drilling will continue until the end of May and is estimated to exceed 5,000m. Refer ASX Release 11 May 2023. The Company confirms that it is not aware of any other new information or data that materially affects the information included in the original market announcement. Contract for Investor Relations Support The Company has entered a contract for investor relations support in North America with non-executive director, Michelle Roth. The contract will see Ms Roth assist with the delivery of the Company’s Investor Relations Strategy as it aims to increase its profile with the North American investor base. Ms Roth led comprehensive shareholder engagement solutions for a worldwide client base for greater than 35 years. Her clients have operated mines or explored in North America, Australia, Africa, Europe and South America for gold, silver, platinum, copper, nickel, and diamonds. The Board, excluding Ms Roth, have determined the services will not impair her independence. The material terms of the contract are payment of A$3,000 per month for a period of 6 months which may be extended at the discretion of the Board (absent Ms Roth). Financial Position The Company had a strong cash balance at quarter end, 31 March 2023, of A$7.26 million. A further $A8.0 million was held in escrow as part of selling the final 20% of the Lithium Joint Venture to Green Technologies Limited (ASX:GT1) in November 2022. Since the quarter’s end, the A$8 million has been released from escrow whereby, A$4.7 million has been received by the Company, with the A$3.3 million balance remitted to Canadian Revenue Agency (“CRA”) as part of Canadian withholding tax obligations. Ardiden expects the residual A$3.3 million to be remitted to the Company following receipt of a tax clearance certificate from CRA in the second half of 2023.

The Company’s 1,088 km2 District-Scale Gold Project is the largest continuous gold land holding in the Uchi Belt, where Barrick, Newmont, Kinross, and Evolution all hold significant gold mine and exploration assets. Ardiden’s strategic landholding is situated on the same geological belt as Red Lake, the ‘Uchi’ Subprovince, which has produced over 30M oz of gold to date and where new Tier-1 gold discoveries are still being made, such as Great Bear Resources’ Dixie Project, which is now under new ownership following the successful CAD$1.6 billion acquisition by Kinross (Figure 2). In addition to its Pickle Lake Gold Project, Ardiden has retained ~13 million shares in Green Technology Metals (ASX:GT1) which it acquired as part proceeds from the sale of Ardiden’s lithium assets.
