KGL Chief Executive Officer Sam Strohmayr said: “Completion of the $300 million equity raising means the Jervois Project is fully funded through construction and into production, marking a significant milestone for KGL. Our focus is now firmly on execution, with development activities advancing across several critical workstreams, including accommodation and mine infrastructure, long-lead process equipment procurement and drilling. These activities demonstrate Jervois’ transition from funding and construction readiness into project execution as we progress towards Final Investment Decision.” Accommodation village and Mine Infrastructure area KGL has executed an approximately A$36 million contract with Northern Transportables Pty Ltd for the design, manufacture, supply, transport, installation and commissioning of the Jervois 180- person accommodation village and associated Mine Infrastructure area buildings. The village will provide 252 single-occupancy rooms, comprising 180 newly manufactured rooms and 72 refurbished en-suited rooms. The first 100 new rooms and principal village facilities are scheduled to be ready for occupation in February 2027, all 180 new rooms are scheduled to be available by April 2027, and relocation and commissioning of the earlier 72 rooms are scheduled for completion in June 2027.
