Pot Pourri of New Data Galleries

Through generous donations of data by individuals and companies, new data galleries and other information containing numerous maps, sections and field photos continue to be constructed for major deposits in a range of commodities:

Gold

  • Gosowong, Indonesia – a new epithermal district with continuing new high-grade discoveries in the Halmaheras in eastern Indonesia (including a detailed discovery history)
  • Karangahake, New Zealand – a classic high-grade epithermal deposit from the Coromandel Peninsula, and the first gold mine in the world to use extraction of gold by cyanide solution
  • Maricunga Belt, Chile – including the La Coipa, Refugio, Cerro Casale and La Pepa deposits in this famous Miocene gold belt in northern Chile
  • Palmarejo, Mexico – an historic epithermal Ag-Au vein deposit in Chihuahua, mined originally by the Conquistadores and currently undergoing renewed exploration and development

Copper

  • Kansanshi, Zambia – a new developing copper mine in the famous Central African Copperbelt
  • Frieda River, Papua New Guinea – a well known and significant porphyry copper deposit undergoing continuing assessment in the same belt as Grasberg, Ok Tedi, Panguna and Porgera
  • Ernest Henry, Australia – one of Australia’s largest IOCG deposits
  • Lisbon Valley, USA – a newly developed sediment-hosted deposit in Utah
  • Pebble, USA – a rapidly growing major Cu-Au-Mo porphyry resource in Alaska

Uranium

  • Alligator Rivers Uranium Field, Australia – an excellent review of recent research on one of the world’s greatest uranium districts
  • Valhalla, Australia – one of Queensland’s undeveloped resources

Zinc

  • Lady Loretta, Australia – a small but classic “Sedex” deposit within the world’s greatest zinc repository, the Mt Isa – McArthur Basin
  • Cerro de Pasco & Colquijirca, Peru – two of the world’s largest zinc deposits, classic examples of replacement deposits in carbonates associated with felsic intrusive centres
  • Menninnee Dam, Australia – once thought to be a stratiform deposit in the Early Proterozoic metasediments of the Gawler Craton, Menninnee Dam has since been shown to be an unusual replacement deposit in basement carbonates and related to the emplacement of the Hiltaba Suite granites, coeval with Olympic Dam

Nickel

  • Jacare, Brazil – a discovery history of this significant undeveloped nickel laterite deposit
  • Sudbury, Canada – comprehensive information from this unique but classic giant deposit
