Geological setting of the Tick Hill Au deposit, NW Queensland, Australia

URL: https://geoscience.data.qld.gov.au/dataset/cr125258 The Tick Hill Gold Deposit is situated 110 km SSE of Mount Isa in NW Queensland, Australia. Whilst Cu Au deposits are common in the Mt Isa block, gold grades are generally less than 1 to 2 gt, and gold rich deposits are rare. One notable exception to this is the Tick Hill gold deposit in the southern part of the Mary Kathleen Domain. Although the Tick Hill deposit presents a mineralization style of great interest to exploration companies, little is known about the deposit other than that it is a gold rich, shear hosted hydrothermal deposit that has been interpreted as a possible end member IOCG deposit. Tick Hill was discovered in 1989, and was mined over a short period of time 1991 1995. Partly because the deposit was developed so quickly, no detailed studies have been published on the deposit or its style of mineralization. Apart from several student theses and some shot overview articles, few details about the deposit are available in the public domain. The overall aim of this report was to correct this situation. The work presented here was designed as a PhD project in the Economic Geology Research Centre EGRU at JCU, undertaken by Mr Truong Le, and combines new petrological, geochemical, mapping and geochronological results, with materials from past exploration reports.
