Horizon Minerals has significantly expanded its nickel portfolio through its recent merger with Poseidon Nickel, adding 422,000 tonnes of nickel metal across multiple projects. Key assets include the Black Swan project, which contributes 178,700 tonnes of nickel, including stockpiles, and hosts several deposits like Silver Swan (12,940t at 9.5% grade) and Golden Swan (6257t at 3.91%). The Lake Johnston project adds 52,000t of nickel, with its Maggie Hays deposit containing high-grade zones above 3%. The Windarra project contributes another 71,500t at 1.64% grade, with historic grades up to 16%. The acquisition strengthens Horizon’s nickel position and provides infrastructure like the Black Swan processing plant, which could be repurposed for gold.
