Horizon Minerals, which had been conducting a milling campaign at its Boorara gold operation in Western Australia, has completed the program and poured first gold.
The fourth and final milling campaign extended from 19 January to 4 February. Overall gold recoveries exceeded expectations with an average throughput of 87 tonnes per hour at the Regal East trial pit and Lakewood facility.
Gold produced from the campaign totaled 1,182 fine ounces, and the first pour milestone met on 28 January.
“The ultimate aim of the trial mining and toll milling from Boorara is to verify the tonnage and grade uplift potential when compared to the current Boorara global resource model,” Horizon Minerals Managing Director Jon Price said.
“Results to date have demonstrated this potential and will inform an updated mineral resource estimate and a maiden ore reserve as part of the consolidated feasibility study ahead of a development decision inclusive of construction of a standalone processing facility at Boorara.
Next step for Horizon is the mine’s full geological and economic summary, which it expected to be completed during the current quarter. A consolidated feasibility study is projected for the September quarter of this year.
Horizon owns 100% of Boorara, located 10 km east of Kalgoorlie’s Super Pit gold operation in Western Australia.
Boorara is divided into three project areas: Royal (Southern), Crown Jewel (Central) and Regal (Northern).
