ASX ANNOUNCEMENT

FY21 Production guidance update

Whitehaven wishes to update FY21 production guidance from a range of 20.6-21.4Mt, to 20.4Mt and reaffirm managed coal sales and unit costs guidance.

Continuing stronger-than-expected production performance at Maules Creek is expected to deliver 12.5Mt for the full year. Combined with production output of 3.8Mt at the Gunnedah Open Cuts, total open cut production is expected to deliver 16.3Mt

FY21 ROM production from Narrabri is expected to be 4.1Mt (4.0Mt YTD). This reduction in guidance is attributable to downtime associated with the acceleration of engineering works to support the longwall operation and a recent geological event. Overhaul works on the longwall and machinery repairs are expected to be completed in the coming days.

Whitehaven has undertaken a program of geo-sensing drilling to provide confidence around the geological conditions in the remainder of the LW109 panel. This drilling has not identified any significant geological features present in the balance of the LW109 block.

FY21 guidance has been updated to take into account the above developments.
