• Assay results include 70m @ 3.4g/t Au and 70m @ 3.0g/t Au
• Infill drilling supports Hemi Definitive Feasibility Study mine plan
• Maiden Measured Mineral Resource of 0.6Moz at Brolga Stage 1 pit

De Grey Mining Ltd has announced the remainder of the infill grade control drilling results from the Brolga deposit at the Hemi Gold Project. The drilling was conducted as part of an Operational Readiness program and is expected to provide continued confidence to potential debt providers as to the quality and consistency of the mineralisation. Mining and processing at Hemi are scheduled to commence with the Brolga Stage 1 (starter) pit, and this infill grade control drilling covers the first 12 months of ore production from Brolga. The results will allow detailed ore production, stockpiling and plant feed scheduling for the critical commissioning and ramp-up phase. Highlights include 70m @ 3.4g/t Au from 36m, 70m @ 3.0g/t Au from 36m, and 36m @ 4.3g/t Au from 70m. The infill drilling has also enabled the reporting of a maiden Measured Mineral Resource Estimate of 12.7Mt @ 1.4g/t Au for 0.6Moz within the Brolga Stage 1 starter pit. The Brolga Stage 1 pit contains a Probable Ore Reserve of 26.9Mt @ 1.64g/t for 1.42Moz of contained gold and has an estimated operating cost, including pre-strip, of approximately A$865/oz. This delivers free cashflow of approximately A$2,200M at the DFS gold price of A$2,700/oz and pays back the capital cost of the Project in under two years.

Year 1 of ore production at Brolga comprises 9.9Mt @ 1.65g/t Au for 525koz of contained gold.
