Geology of the Enterprise Mine, Pine Creek, Northern Territory

Gold mineralisation at the Enterprise Mine, 230 km south of Darwin, occurs within folded and metamorphosed sediments of the Lower Proterozoic Burrell Creek Formation adjacent to the Cullen Granite. The mineralised zone, which occupies an area of approximately 800 m x 300 m is local- ised by a moderately tight, upright symmetrical anticline which plunges shallowly southwards._x000D_
The anticline has been disrupted by numerous faults on which the maximum movement is 40 m. Gold is associated with quartz and sul- phide veins which are present as saddle reefs, inter-reef veins and fault controlled reefs._x000D_
it occurs within the veins or their alteration haloes, either as free gold (2 - 50 per cent of total gold content) or intimately associated with sulphides, principally arsenopyrite and Pyrrhotite.
