ABSTRACT:Blackham Resources Ltd (ASX: BLK) (“Blackham”) is pleased to provide a revised Mineral Resource estimate for the Matilda-Wiluna Operation of 96Mt @ 2.2g/t for 6.7Moz of gold, which includes Indicated Resources of 69Mt @ 1.7/t for 3.88Moz. Mineral Reserve calculation is currently underway and will be reported in the near future. The changes in the resource results from the combined effects of successful further drill testing in some areas, mining depletions at Matilda, a change of resource modelling process for some deposits (ordinary kriging (‘OK’) to localised uniform conditioning (‘LUC’)), revised pit shells and the initial inclusion of the Wiluna Tailings mineralisation. Approximately 1.3Moz of the resource base is free-milling and can be processed through the existing Wiluna CIP plant. Feasibility studies are currently being completed on Blackham’s 620,000oz of tailings with a view to treating them through the existing free milling circuit. The remainder of the mineralisation is sulphide ore requiring treatment through the Wiluna sulphide circuit. Blackham is working towards the completion of the feasibility study to justify the capital to re-establish the sulphide circuit and treat the sulphide ores. Subject to a successful completion of the feasibility study and sourcing of the required funding, it is expected a decision to proceed will be made in 2019, enabling significantly higher gold production through exploiting the large and higher-grade feed sourced from both deeper pits and large scale underground mining
