Energy Resources of Australia produced 489 tonnes of uranium oxide during the June quarter, a 25 per cent increase on the same period a year earlier.
The company said all ore milled was taken from existing stockpiles, and no exploration was conducted during the quarter.
The Rio Tinto-owned uranium miner announced late last year that Kakadu's traditional owners had rejected its plans to expand development of the key Ranger uranium mine in the Northern Territory.
Following a strategic review, ERA said on Tuesday it plans to continue using its existing ore stockpiles, which it says will last until late-2020, and to use part of the proceeds for rehabilitation of the Ranger area.
The company in April also signed a deal to borrow up to $100 million from Rio Tinto - if needed - to reintegrate the rehabilitated site into the surrounding Kakadu National Park.
