Quotation of Zinc plating Slag on April 30

Rockfire Resources announced that GeoRes Mining Consultants had commenced a maiden JORC Inferred germanium resource estimate at its 100%-owned Molaoi zinc deposit in Greece. The work will also remodel the principal zinc lodes and produce an updated Inferred zinc resource, with results expected within four weeks. Drilling to upgrade the existing resource from Inferred to Indicated is continuing, with hole HMO-022 currently in progress. Molaoi currently hosts a JORC Inferred Mineral Resource of 15.0 million tonnes grading 7.26% zinc, 1.75% lead and 39.50 g/t silver, using a 4% lower-grade cut-off. This equates to approximately 1.09 million tonnes of zinc, 260,000 tonnes of lead and 19.1 million ounces of silver. Portable-XRF readings from HMO-022 also identified a roughly 1-cm-wide chalcopyrite vein with a single reading of 12% Cu; Rockfire explicitly cautioned that the pXRF reading is preliminary and is not a substitute for laboratory assays.

5N Plus planeja expandir sua unidade em St. George, Utah, em aproximadamente 50%, com conclusão prevista para o segundo semestre de 2027. O local transforma antimoneto de índio e outros materiais especiais em materiais semicondutores, wafers, substratos e componentes selecionados, com capacidades de recuperação, purificação e crescimento de cristais. Novos equipamentos serão instalados progressivamente, mas a capacidade específica de InSb não foi divulgada; o valor de 50% refere-se à expansão da instalação, não à demanda de índio.
