Hilton Mine


A large operating, underground silver-lead-zinc mine located in NW Queensland, closely related to the Mt Isa mines 20km to the south, but the mineralised section is only one-third the thickness of the Mount Isa ore zone, extending from 300m to 1,000m depth for 6.5km. It is more folded and more interrupted by faults and dykes. Ore zones are from 3m to 25m thick. 11 orebodies have been assessed, the two to be mined containing 24Mt and providing a ten-year mine life at a production rate of 2.5Mt/y.

As of mid-2005, Xstrata stated the reserves as: George Fisher South – 10Mt grading 7.8% zinc, 5.6% lead and 130g/t silver. George Fisher North – 11.4Mt grading 8.8% zinc, 4.7% lead and 92g/t silver. Resources at the South orebody were 22Mt at 8.9% zinc, 6.5% lead and 150g/t silver, while those at George Fisher North stood at 14Mt at 10% zinc, 5.15% lead and 100g/t silver.
