Delta Lithium has appointed Bell Potter Securities Limited (“Bell Potter”) as financial adviser to conduct the Strategic Review and explore various options for Mt Ida Gold. Delta Lithium will use the Strategic Review to determine how to best monetise the substantial gold potential of the Baldock deposit, and broader assets package that comprises Mt Ida Gold. The decision is in line with Delta Lithium’s strategy to maintain a principal focus on its lithium assets at the Mt Ida Lithium Project and the Yinnetharra Project. There is no guarantee that the Strategic Review will result in any specific transactional outcome. Commenting on the Strategic Review Managing Director, James Croser said: “Delta Lithium's Strategic Review of Mt Ida Gold is a considered decision, catalysed by the significant recent growth in its Mineral Resource, and its emerging potential as a significant high-grade gold operation. “The broader Mt Ida Project is a fantastic asset, hosting both sizeable gold and lithium Resources. Our shareholders know our core focus is lithium, and we will always look at the best way to deliver value creation for our shareholders. “With the body of technical work we have recently completed on the gold opportunity, including a meaningful Resource upgrade, an internal Scoping Study, metallurgical test work, and approvals for open pit and underground mining, it makes sense for us to consider all options for its ongoing development. 1,Refer to the Company's announcement titled '[Mt Ida Gold MRE Update]' dated [28 June 2024] available on its ASX Markets Announcement Platform for further information. ASX ANNOUNCEMENT 26 September 2024 We will assess the outcomes of this Strategic Review against Delta Lithium's own development options, to ascertain the best way forward.” Mt Ida Gold Mt Ida is located approximately 100km northwest of Menzies, and approximately 225km by road from Kalgoorlie in Western Australia’s prolific Eastern Goldfields mining region (Figure 1). The Project area resides on granted mining leases and is approved for open pit and underground mining at Baldock, which hosts the majority of the high-grade gold Mineral Resource at Mt Ida. The Strategic Review will progress in parallel with ongoing development studies and exploration. The recent scoping study contemplated a toll treating or ore purchase agreement for the gold resource only, while preserving the lithium resource for a future investment decision. Figure 1: Location of Mt Ida Project with Gold and Lithium Resources stated 2 ASX ANNOUNCEMENT 26 September 2024 Delta Lithium has completed metallurgical test work with favourable results, has received all permitting for both open pit and underground mining, and has identified additional drill targets with the aim of growing the existing 752koz resource to >1Moz and position Mt Ida as a genuine standalone scale project. Ongoing work at Mt Ida includes advancing metallurgical and geotechnical studies to a sufficient level of detail for a future Reserve Statement, and progressing towards completion of a Prefeasibility Study. Studies for a standalone process plant option are also continuing, along with extensional and exploration drilling to grow the MRE.
