Keel hosts a historical 2020 JORC Inferred Mineral Resource Estimate of 11.2 million tonnes grading 4.5% zinc, 17 g/t silver and 0.6% lead, at a 3% zinc cut-off, containing approximately 510,000 tonnes of zinc, 72,000 tonnes of lead and 6.14 million ounces of silver. Northmin has secured the database, 3D wireframes and block model supporting the estimate, based on 83 diamond drill holes. Following final grant of PLA 186, the company plans database validation, updated 3D geological modelling, permitting and verification drilling, with a commitment to drill at least two diamond holes during the first two years of the licence

【Flash | Sumitomo Chemical Starts Mass Production of 4-Inch InP Epiwafers】

Sumitomo Chemical has established mass production of 4-inch Indium Phosphide (InP) epitaxial wafers at its Ibaraki Works and begun commercial sales, becoming one of the few Japanese epi houses capable of stable volume production. The products target photonic-electronic convergence devices for AI data centers and high-speed networks. The company aims to generate approximately JPY10 billion in InP epiwafer sales by the mid-2030s. SMM views the move into commercial production as a direct addition to Japan’s InP material supply and supportive of medium-term high-purity indium demand. Annual wafer capacity, output and indium consumption were not disclosed.
