Announcement PDF ASX ANNOUNCEMENT 3 November 2023 ` Mt Ida Lithium Project receives Approval of Mining Proposal and Mine Closure Plan Highlights: • The WA Department of Mines, Industry, Regulation and Safety (DMIRS) has approved the Mining Proposal and Mine Closure Plan for open pit mining operations at Mt Ida. • This approval, in conjunction with other key permitting already received (Native Vegetation Clearance Permit and 5C Water Extraction Licence) provides for the ability to commence open pit mining operations at Mt Ida. • This is a key milestone in the Company’s strategy to achieve ‘shovel ready’ status on Phase 1 of mine development at Mt Ida and further de-risks development of the concentrate project. • Approval of open pit mining now positions the company to take advantage of the opportunity to exploit shallow gold ore that is overlying lithium ore2. • Detailed technical work is now underway based on the recent Lithium MRE update and the maiden Gold MRE announced by the Company2. Delta Lithium Limited (ASX:DLI) (“Delta” or the “Company”), is pleased to advise that it has achieved a key milestone in the development of its Mt Ida Lithium Project (Mt Ida or Project) in Western Australia. This Approval follows the submission in March of this year of a Mining Proposal and Mine Closure Plan to the WA Department of Mines, Industry, Regulation and Safety (DMIRS), in relation to open pit mining operations1. Commenting on the approval Managing Director, James Croser said; “With all statutory approvals for commencement of mining now received, it is accurate to say that Mt Ida is indeed shovel-ready. The combined lithium and gold resources present a compelling mining project. The Company is now in an enviable position at Mt Ida to simultaneously progress studies on the lithium concentrate project; while also progressing discussion around deriving value from high-grade gold.” ENDS Release authorised by the Board of Delta Lithium Limited.
