ABSTRACT:Blackham Resources Limited (ASX: BLK) (Blackham or the Company) is pleased to present final results from the Wiluna free milling drill programme. During March’18 to May’18, Blackham’s exploration team drilled 133 RC holes (11,612m) focused on delineating further free milling open pit reserves over the 3.7kms of strike at the Wiluna Mine. The results reported are from the final 66 holes received (5,326m). All Wiluna Mine drilling assays have now been received and will be incorporated into Blackham’s next resources and reserves update anticipated in the September ’18 quarter. This is a follow up programme to the 77,000m of drilling completed during 2017, which successfully delivered probable reserves of 669,000oz (7.7Mt @ 2.7g/t Au) within Wiluna open pit cutbacks. The A$1,600 Au/oz pit optimisations shown below were completed immediately prior to the latest drilling, and confirm the potential for open pit cutbacks and new free milling open pits to be developed at the Wiluna mine site. These latest drilling results are expected to support substantial increases to open pit resources and reserves within open pits. Current drilling is focused on free milling ores above the top of fresh rock (generally top 60-80m) that metallurgical test work has confirmed are viable feed sources for the Wiluna CIL plant, with average leach recoveries on the oxide and transitional ores being 90.8% and 84.3%, respectively, after 24 hours. The Blackham management team believes the free milling ores within the existing Wiluna Mine footprint are an attractive feed stock for the currently operating mill and allows for fast-tracking mining approvals.
