THE DRILL SERGEANT: Blackham Resources (ASX: BLK) declared its latest drilling program at the company’s Wiluna and Matilda gold operation in Western Australia has identified extensions to shallow oxide and transitional mineralisation.
Blackham Resources said the results indicate potential for new open pits close to the Wiluna plant.
During March and April, Blackham’s exploration team drilled 130 RC holes focused on delineating further free milling open pit reserves over the 3.7 kilometres of strike at the Wiluna Mine.
The company said the Wiluna Mine drilling is expected to conclude in mid-May and resources will be re-estimated at that time.
“Pit optimisation studies completed immediately prior to this drilling demonstrate the potential for open pit cutbacks and new open pits to be developed at the Wiluna mine site,” Blackham Resources said in its ASX announcement.
“The $1,400 and $1,800 shells are similar in extent, which shows open pit mining is expected to be economic at a range of potential gold prices.
“These latest drilling results are expected to support substantial increases to open pit resources and reserves within open pits.”
Blackham said the potential for increased sulphide resources was highlighted by drill hole WURC0508, which intersected high-grade Wiluna shear-style sulphide mineralisation of:
22 metres at 3.29 grams per tonne gold from 97m down-hole, including 2m at 5.15g/t gold and 3m at 8.33 g/t gold.
Balckham said these zones show improving grade and thickness of Starlight mineralisation at depth and remain open for follow-up drill testing.
“Wiluna Mine final drilling results from outstanding holes are expected by the end of May, with resource and reserve updates to follow,” the company said.
“Golden Age underground drilling is ongoing and Lake Way drilling is due to commence this month.”
