[{"type":"text","content":"\n\n26 June 2025\nRockfire Resources plc\n(\"Rockfire\" or the \"Company\")\n \nMolaoi Update\nRockfire Resources plc (LON: ROCK), the base metal, critical mineral and precious metal exploration company, is pleased to provide this update regarding the on-going development activities at its 100%-owned Molaoi zinc deposit in Greece.\n \nGEOLOGICAL LITHOFACIES MODELLING\nThe completion of a 3-dimensional (\"3D\") lithofacies model of the Molaoi Project has provided important geological support for the 2024 mineralisation model.\n· The 3D modelling improves targeting for future exploration and is expected to lead to significant resource growth along the 5 kilometres still to be drilled towards the north.\n· The Molaoi zinc/silver/lead/germanium deposit consists of four dominant, north-south layers of sandstone, interlayered with lava flows. The sandstone units are the primary hosts for economically significant zinc mineralisation.\n· At the Kalamaki prospect, where most of the drilling has been done, the highest-grade and thickest mineralisation is within the thickest sandstone layers. These economic concentrations of mineralisation are understood to have formed along or close to active faults at the time the rocks were being formed. These are termed \"growth faults\".\n· The recent study supports a model whereby hot, zinc-rich fluids were injected up and along fractures, with zinc moving through and being precipitated into the porous sandstone units.\n· This model has highlighted other positions along strike where similar faults may have been active and will assist to identify zones with thicker and higher-grade mineralisation.\n· More than half a dozen sites are now deemed favourable targets for exploration along strike. These targets are supported by surface enrichment of zinc, and/or old workings and/or historical drill holes which successfully encountered high-grade zinc mineralisation.\n \n\nMap showing the location of growth faults with coinciding sandstone layers, surface zinc anomalism and historical drill holes which intersected high-grade zinc. These are well-defined targets for the discovery of further tonnes of zinc, l...
