The Broken Hills district is located on the southern portion of the Coromandel Peninsula, on the east of the North Island of New Zealand. The district is bounded to the north by the Hikuai township, to the east and south by the Kopu-Hikuai highway (State Highway 25A) and to the west by the Coromandel Ranges. The district is loosely defined by an area of low aeromagnetic signal, understood to be caused by the destruction of magnetite in volcanic rocks by hydrothermal fluids, and which therefore delineates the likely hydrothermal footprint of a paleo-hydrothermal system. The peninsula itself comprises the remnants of the extinct Coromandel Volcanic Zone, active between 18 and 2 Ma, producing steep, mountainous morphology, and numerous other epithermal deposits and prospects.
