Major Mines & Projects - Mining Intelligence and News
Although blasting will continue to be in 15 m benches, the mining will take place in 4 m slices. Production drilling is done using Pit Viper 351 and BE 49R drills, both with 12½ inch (31.75 cm) drill bits. The drill pattern varies depending on ore or waste. Smaller drills are used for pre-splitting and pit wall control.
