Admiralty Resources NL (ASX: ADY) has further advanced production at its flagship Mariposa magnetite Iron Ore Project in Chile amid continuing solid demand for iron ore. The March Quarter 2026 saw the Company continue its production ramp-up, with a focus on enhancing the quantity and quality of the final product. Total quarterly mining was 96,005 tonnes, down 18.8% on the prior quarter, while total quarterly iron ore concentrate production was 42,992 tonnes, down 5.8% on the prior quarter. The mineral processing plant is continuing operation while awaiting the electrical connection necessary for additional crushing and grinding equipment, which is expected to increase operational efficiency and the monthly volume of minerals processed. After Trafigura sourced a vessel, a total of 58,087 tonnes of Iron Ore Concentrate was loaded onto the MV DAWN FZ at Las Losas Port for the Company's second overseas shipment. The vessel departed port on 1 April 2026 bound for customers in China. Admiralty also completed geological drilling totalling 763.08 metres in March and plans to blast 50,000 tonnes of waste rock in April 2026. The Company has completed the installation and commissioning of the substation and transmission line for power operations and is progressing various other infrastructure upgrades, including the tailings filter press system, concentrate stockpile, and tower mill foundation. The Company is also reviewing the regulator's responses to the Mariposa Transport DIA (environmental impact statement) and seeking approval for the purchase of industrial water from Agrosuper's water treatment plants.
