Whitehaven has upgraded the resources and reserves at its Blackwater mine in Queensland, strengthening the miner’s long-term production outlook.
Whitehaven said Blackwater’s total recoverable reserves increased 91 per cent to 365 million tonnes (Mt) from 191 million Mt, while total coal resources rose 6 per cent to 1,919Mt from 1,817 Mt.
The upgrade was underpinned by improved geological confidence from the inclusion of 4,267 structural and 211 quality drillholes, alongside refined economic assumptions and the inclusion of additional prospective mining areas that support continued long-term production.
Whitehaven CEO Paul Flynn said the latest results reflect steady progress in integrating the Queensland operations the company acquired from BMA.
“This uplift to resources and reserves at Blackwater unlocks future mining areas and reinforces its position as a long-life asset and the strong potential for growth and optionality at the Blackwater Mine,” Flynn said.
Marketable reserves increased to 298Mt from 169Mt, driven by the upgrade in recovered reserves.
The updated marketable reserves estimate considers mine processing data, confirming alignment between modelled and achieved yields.
