Vulcan Energy Chair, Dr Francis Wedin, commented: "We are pleased to have someone of Roberto's calibre join our Board. He brings valuable skills and experience in the construction of large-scale, global infrastructure projects, which will be of significant benefit to Vulcan as we construct Project Lionheart. He also has extensive management and corporate governance experience, having been a Director of several listed companies across jurisdictions including the US, Chile, Peru, Spain, Portugal, Denmark and Australia. On behalf of the Board and management team, I warmly welcome Roberto to Vulcan and look forward to his contribution on the Board as we build our lighthouse European lithium and renewable energy project."

About Vulcan Energy

Vulcan Energy (ASX: VUL, FSE: VUL) is building the world's first integrated carbon neutral lithium and renewable energy business to decarbonise battery production. Located in the Upper Rhine Valley Brine Field between Germany and France, Vulcan's Lionheart Project (Lionheart) is a lighthouse project for Europe's energy and critical raw material resilience.

Lithium is to be extracted from low impurity geothermal sub-surface brines using Vulcan's industry-leading VULSORB® technology. Naturally heated, the brine powers production and conversion of lithium to battery-quality material by creating a renewable energy co-product for use in operations, with surplus sold into the local energy market. This integration, technology and favourable brine chemistry collectively enables one of the lowest cost lithium operations globally.

Extraction is only the starting point for Vulcan. The Company has reimagined mining using innovation to integrate and capture more of the value chain. The Company has made its positive Final Investment Decision on Lionheart, construction is underway, offtake contracted and further phases of production are in planning.
