23.01.2022 The second part of our Andean Porphyries 2017-18 International Study Tour has been completed. This professional development course was aimed at geologists within the minerals industry, and was conducted between 4 and 18 June 2018. It attracted geologists form the majors, including Rio Tinto, BHP, Vale, Sumitomo and MMG, from Australasia, China, Japan, Canada, USA, Peru, Chile and Brazil. The tour visited six major porphyry Cu-Mo, Cu-Mo-Zn, Cu-Au and Au systems, from Paleocene... to Miocene in age, and from the Central Andes in southern Peru, through the Peruvian Andes to the Northern Andes in Ecuador. Deposits included 'classic' porphyry, porphyry-skarn, porphyry-breccia and porphyry-epithermal deposits, and their supergene derivatives. Participants were able to take any 3 or more days, up to the full tour. For details of the deposits visited, dates, conditions and to view the tour photo album to see who went and what they saw, go to www.portergeo.com.au/andeanporphyries2018
22.01.2022 Well, the CopperBelts 2014 International Study Tour has been completed, and very successfully. The final tour group totalled over 40 geologists from a wide range of companies from around the world. We visited some of the most economically important and geologically significant sediment hosted copper deposits in the world. We were enthusiastically welcomed by the expert geological staff at each site, who provided a series of very interesting, enlightening and professionally re...warding technical visits. Each involved an overview briefing or series of lectures, mine or field inspection of the ore and host rocks and sessions with drill core. Sites visited included the classic Zambian Copperbelt deposits at Mufulira, Nkana-Mindola and Nchanga-Konkola; the Zambian Domes Region mines at Lumwana and Kansanshi; the Congolese Copperbelt ores at Tenke-Fungurume, Kolwezi, Kamoa, Kinsevere and Mutunda, the Kalahari Belt Boseto Project deposits in Botswana and the KGHM Kupferschiefer complex in Poland. These visits were supported by expert field and classroom workshops and lectures.

15.01.2022 My copy of the new AusIMM Australian Ore Deposits volume - to which I contributed - arrived today and is on my desk !!! This is the 6th in the series, the first... of which was published in 1953. It comprises ~900 pages containing over 175 papers describing most of the significant ore deposits in Australia. For various reasons, such as mine closures and unavailability of staff, the responsible companies were unable to contribute papers for a number of key deposits. As this would leave a gap in coverage, in mid April of this year, the editor, Neil Phillips, asked if I could prepare a number of review papers based on information in the public domain, some of which I had already researched for the PorterGeo online ore deposit database. To this end, I contributed 8 papers on McArthur River Zn-Pb-Ag, Boddington Au-Cu, Cadia Au-Cu, Telfer Au-Cu, Nifty-Maroochydore Cu, Stawell Au and Angas Zn-Pb-Ag-Au, and a paper comprising a collection of 2 to 3 page extended abstracts on White Dam Au, Mt Peake V-Ti-Fe, O'Callaghans W, Agnew Au and Mt Cattlin Li-Ta. All this took ~4 months of work and it is great to see the result. This volume is available to purchase online as a hard copy or on USB from www.ausimm.com.au See more
07.01.2022 During early 2015, Mike Porter was invited to contribute two papers to a special issue of Geoscience Frontiers "Giant Mineral Deposits". These were submitted in June and August of the same year, and have been published online in the May issue of the journal. The papers are open access and may be downloaded at no charge, as follows: The geology, structure and mineralisation of the Oyu Tolgoi porphyry copper-gold-molybdenum deposits, Mongolia: A review; Geoscience Frontiers 7 ...(2016), pp. 375-407; DOI 10.1016/j.gsf.2015.08.003. www.sciencedirect.com/science/article/pii/S1674987115000924 Regional tectonics, geology, magma chamber processes and mineralisation of the Jinchuan nickel-copper-PGE deposit, Gansu Province, China: A review; Geoscience Frontiers 7 (2016), pp. 431-451; DOI: 10.1016/j.gsf.2015.10.005. - www.sciencedirect.com/science/article/pii/S1674987115001231 See more
06.01.2022 Porter GeoConsultancy conducted a geological tour to a selection of the most significant sediment-hosted copper provinces and deposits in Southern and Central Africa (Botswana, Zambia, DRC) and Europe (Kupferschiefer in Poland) during May 2014. The mine and project visits were complemented by context setting overview expert workshop(s). Participants were able to take any 2 or more days up to the full tour, as suits their availability, interests and budget. More details are av...ailable from the tour website.

06.01.2022 The Andean Porphyries 2017-18 International Study Tour has two modules. The first, Andean Porphyries 2017 was successfully completed between Sunday 23 and Saturday 29 April 2017, and visited four major deposits in the Central Andes of Chile. The second, Andean Porphyries 2018 in June 2018 will include the remainder of the program involving 6 deposits distributed from the Central Andes in southern Peru, through the Peruvian Andes to the Northern Andes in northern Ecuador. Fo...r detail go to: www.portergeo.com.au/andeanporphyries2018 This tour is open to all geologists world wide. They may take any 3 or more days up to the full tour, as suits their interest, availability or budget. This professional development course will provide a comprehensive overview of the scope and variability of the occurrence of 'porphyry related' deposits, and their common and contrasting characteristics. It will include: each of the styles of porphyry related deposits & commodity groupings, including 'classic' porphyry, porphyry-breccia, porphyry-skarn, porphyry-epithermal and supergene deposits of Cu-MoZnAu, Cu-Au & AuCu, the three differing, distinct and laterally contiguous, geotectonic zones that host significant porphyry mineralisation in the Andean Orogen, the northern, Peruvian and central Andes, a representative selection of deposits, from central Chile in the south, to northern Ecuador in the north, deposits spread across the principal temporal clusters of emplacement, from Cretaceous to Miocene/Pliocene.
05.01.2022 Over 40 geologists from around the world registered for CopperBelts 2014. Registrations have now closed and the tour is about to start !!!
