The mine has already produced 2.6Mt of coal on a 100% basis, 27% ahead of Macquarie Wealth’s forecast.
“The strong production result in the June quarter means the scheduled longwall change out will now happen two weeks ahead of plan,” Macquarie said in a research note.
“Production outstripped sales and coal stocks built during the June quarter.
“Stockpiled coal will be sold during the September quarter during the longwall change out.”
Pre-production coal production for the quarter of 1,403kt was ahead of 1,230kt forecasts, according to Macquarie.
“The CHPP was commissioned during the quarter with better than expected yields and product quality achieved,” it said.
