Snapshot	A Definitive Feasibility Study on retreating the gold tailings at Windarra and Lancefield was completed in July 2021. On July 31, 2024, Poseidon Nickel entered into an agreement with Encore Minerals Pty Ltd. to develop the Windarra Gold Tailings Project, using Draslovka proprietary Glycine Leaching Technology (GLT) and other patented technology. The agreement includes an up-front non-refundable payment of $250,000 upon signing of the agreement and the commencement of a testing period. It is a staged framework agreement with a final agreement to be entered into upon the completion of the test work. Pursuant to the Agreement, Poseidon will receive a total of $1.25 million in cash, an NSR royalty of 3% on production and $1.6 million towards the existing rehabilitation bond. The funding, development, operation, closure and rehabilitation of the project will be the responsibility of Encore Minerals.

• Tailings

Summary:

Between 1981 and 1994, approximately 5.1 Mt of gold ore was treated at an average head grade of 5.1 g/t gold producing over 700,000 ounces of gold at a recovery of 84.2%. The gold tailings were isolated from the nickel tailings and deposited initially in the South dam and then the North dam from 1988. The North dam contains approximately 80% of the gold tailings tonnage. A minor proportion of gold tailings was deposited on top of the Central dam to assist with capping the nickel tailings prior to rehabilitation of the Central dam.

Poseidon is considering development of the Windarra Gold Tailings Project, which comprises the Windarra Gold Tailings Mineral Resource contained within the North and South tailings dams (Windarra) and the Lancefield Gold Tailings Mineral Resource contained on License To Treat (LTT) tenement 700-3709 (Lancefield). The Mineral Resource comprises 4.75 Mt at the Windarra North and South dams at an average grade of 0.73 g/t gold and 1.21 Mt at Lancefield at an average grade of 1.27 g/t gold, all classified as Indicated resources. There is a total of approximately 161,000 ounces of gold contained within the Project Mineral Resource at Indicated classification. The Project also has access to an additional 0.38 Mt at an average grade of 1.20 g/t gold at Lancefield currently classified as an Inferred resource. With additional resource definition drilling it is considered likely this material would be reclassified to an Indicated resource also.
