The updated MRE features a 64% increase in the Total\nMineral Resource at the Severn deposit, reaching 8.54Mt at 0.82% Sn for 70,002\ntonnes of contained tin.\n\nThis pivotal upgrade brings the total Heemskirk Tin Project Resource to\n13.36Mt at 0.86% Sn, representing 115.3kt of contained tin.\n\nA major highlight is the 125% increase in the Indicated Resource category,\nwhich now stands at 6.05Mt at 0.84% Sn for 50,739 tonnes of contained tin.\n\nConsequently, Heemskirk remains the highest-grade undeveloped tin project in\nAustralia and ranks third highest globally among peer projects. Across its\ncombined assets, including the nearby St Dizier deposit, Stellar’s Total\nResource Base now exceeds 129kt of contained tin.\n\nThis latest Severn upgrade follows the recent 2026 MRE update for the adjacent\nQueen Hill deposit, which delivered a 25% increase in contained tonnes and a\n32% increase in contained tin.\n\nStellar is advancing its Prefeasibility Study (PFS), anticipated for\ncompletion in 2H 2026.\n\nThis significant milestone follows a recent $17 million cornerstone investment\nfrom Metals X Limited (ASX:MLX).
