Perth, Aug. 21, 2024 (GLOBE NEWSWIRE) —

Perth, Western Australia/ August 21, 2024/Perseus Mining Limited (ASX/TSX: PRU) wishes to update the estimates of the Mineral Resources and Ore Reserves at each of its African operations as summarised in Table 1 and Table 2 below, and detailed in this report. Highlights

• Perseus Mining has delivered another year of organic growth from resource definition drilling and studies, leading to new Measured and Indicated (M&I) Mineral Resources and Proved and Probable Ore Reserves, adding to the long-term sustainability of the Group’s production profile.

• The Group’s total M&I Mineral Resources at 30 June 2024 are estimated to be 115.9 Mt grading 1.31 g/t gold, containing 4.9 Moz of gold, compared with the estimate of 30 June 2023 of 122.8 Mt grading at 1.31 g/t Au for 5.2 Moz of gold.

• Group Proved and Probable Ore Reserves are now estimated at 64.9 Mt at 1.39 g/t gold for 2.9 Moz, compared to the estimate of 30 June 2023 of 73.8 Mt at 1.45 g/t gold for 3.4 Moz of gold.

• Inorganic growth during FY24 included the acquisition of OreCorp Limited including its primary asset, the Nyanzaga Gold Project. In compliance with Canadian Instrument NI 43-101 these Mineral Resources and Ore Reserves remain treated as Foreign Estimates, not current Perseus estimates, until further work can be completed.
