No, EXU doesn't own the Joint Ore Reserves Committee.
They do however, have a Mineral Resource of 675,000oz gold from 11.7 Mt grading 1.79 g/t Au and an Initial Ore Reserve of 485,000 oz gold from 7.2 Mt grading 2.09 g/t Au, for the Tampia deposit alone, if that's what you mean.
Very easy information to find.
