The Coronation Hill uranium prospect Katherine - Darwin area, Northern Territory

The uranium prospect at Coronation Hill is situated on the south side of the valley of the South Alligator River, 75 miles from the town of Pine Creek, from which it is accessible by trucks in the dry season. The surface showings consist of discontinuous exposures of autunite over an area approximately 400 feet square upon the north-eastern corner of Coronation Hill, an isolated feature within the river-valley. The rocks present are of Proterozoic age. Mineralization is found within two deeply-weathered members of a sedimentary-volcanic complex which forms the basal member of the Upper Proterozoic: the rocks of the prospect may be in part of Lower Proterozoic age. Sulphide mineralization accompanied by a secondary uranium mineral has been found at one point by diamond drilling: the sulphides are principally pyrite and the nickel sulphide bravoite. Mineralization is associated with a partly crushed and highly altered zone adjacent to a mass of Upper Proterozoic sandstone which overlaps the older and lower rocks. The structure is imperfectly understood and the control over mineralization has not been established. Development work, including costeaning, pitting, diamond drilling (1006 feet in two holes) and geophysical surveys (Radiometric, magnetic and electrical) has found no mineralization of economic grade, although it has shown the presence of alteration and sulphide mineralization which indicate that the full potentialities of the prospect have not yet been determined. Further work sufficient to complete preliminary exploration would require a minimum of 2500 feet of diamond drilling on underground operations at least equivalent to 1000 feet of drifting and crosscutting. Diamond drilling is somewhat preferable, since it can reach more deeply below the weathered zone. Only after completion of this additional work can it be determined whether or not the prospect is of economic value.
