Genesis Minerals Limited (Genesis) (ASX: GMD) is pleased to advise that is has completed the acquisition of the Leonora assets from St Barbara Limited (St Barbara) (ASX: SBM).

The transaction is on-strategy, fully funded, and delivers unique synergies to the prolific Leonora District that will seek to generate significant long-term shareholder value.

In parallel with the transaction, Genesis has been advancing the Leonora Gold Project (LGP) comprising the Ulysses, Admiral, Orient Well and Puzzle deposits, to ensure the Genesis assets meet the long-term targets set as part of the acquisition of St Barbara's Leonora assets. Genesis is pleased to announce a maiden LGP Ore Reserve of 9.8Mt @ 2.0g/t for 630koz. Feasibility level studies have been conducted for Ulysses, Admiral, and Orient Well, whilst a Pre-Feasibility level study has been conducted for Puzzle. The LGP Ore Reserves includes two new development projects, Admiral open pit and Ulysses underground, that will be paired with the Gwalia mine to fill the underutilised Gwalia mill (refer pages 4-6 for project updates). Given the recent focus on Mineral Resource to Ore Reserve conversion and mine development, only minor changes are reported for the LGP Mineral Resources, updated to 41.0Mt @ 1.6g/t for 2.0Moz; compared to 39.3Mt @ 1.6g/t for 2.0Moz at 29th March 2022). All deposits remain open along strike and at depth. Group Ore Reserves stand at 3.9Moz and Group Mineral Resources stand at 15.0Moz. Genesis will complete a strategic review of Gwalia in the December half 2023 and provide a five-year outlook to the market in the March quarter 2024

Managing Director Raleigh Finlayson said the transaction has created a leading Australian gold house, 100% focused on Leonora. 'Most importantly, we can now get on with the job of unlocking the unique synergies and delivering the long life, 'margin over ounces' Leonora business plan we have clearly articulated to shareholders' Mr Finlayson said. 'The next six months will be focused on a strategic review of Gwalia, re-building the foundations to ensure a new lease of life for this prolific gold asset. 'On behalf of Genesis, I would like to thank St Barbara for its co-operation throughout the transaction and extend a warm welcome to our new colleagues at the Gwalia operation who are now part of the Genesis team.'

This announcement is approved for release by Raleigh Finlayson, Managing Director of Genesis.

Economic Outcomes

The Ore Reserve estimate is based on a Pre-Feasibility level of accuracy with inputs from mining, processing, transportation, sustaining capital and contingencies scheduled and costed to generate the Ore Reserve cost model. Load and haul mining costs are built up from first principles by Genesis Mining Services based upon life of asset ownership costs and operating costs. Drill and blast costs are derived directly from tendered prices. Road haulage costs are from budget rates supplied by a reputable goldfields haulage contractor. Site capital costs are sourced from tendered pricing for infrastructure. Processing and G&A costs are sourced from the most recent operating costs for Dacian's Mt Morgans Mill. The Ore Reserve returns an economic outcome based on the assumed commodity price and cost estimation, and the Competent Person is satisfied that the project economics that make up the Ore Reserve are suitable based on the mine design, modifying factors, assumptions, and environment. Sensitivity analysis has indicated that the project drivers are gold price, mining and metallurgical recovery followed by operating expenditure.
