PorterGeo Database - Ore Deposit Description

The Mt Leyshon gold deposit, is located 24 km south of Charters Towers in northeast Queensland, Australia (#Location: 20°17'31"S, 146°16'15"E) The deposit is hosted by the Permian Mt Leyshon Intrusive and Breccia Complex (a subvolcanic porphyry-breccia complex) which occurs within an ~100 km-long northeast-trending corridor of sub-volcanic Permo-Carboniferous rock scharacterized by

Geology of the Mt. Leyshon gold deposit, Australia: a ...

The facies architecture of the Mt. Leyshon breccia complex is reinterpreted as a subvolcanic intrusive breccia and igneous complex. The main pipe breccia defines the margins of the complex, which also contains a number of smaller breccia pipes and dykes, associated with porphyritic intrusives. The grossly rhombohedral shaped main pipe breccia has antler-like geometries with inter-fingering ...

At both Mt Leyshon and the Great Eastern Target, broad resistivity lows occur on top of and at the sides of a deep reverse polarised magnetic core. At Mt Leyshon, the low resistivity reflects gold mineralisation within overprinting alteration surrounding the early hot intrusive phase defined by the deep reversely magnetised core.
