Gold (Copper) Short Course: Intrusion-related, Porphyry and Carlin-type Deposits

By Craig Hart (Director, MDRU – UBC, Vancouver), Adi Maryono (Consultant, Jakarta) and Steve Garwin (Consultant, Perth)

Venue: Sanur Paradise Plaza Hotel Time: 08:30am - 17.30pm.  This course is being held in conjunction with the East Asia : Geology, Exploration Technoilogy and Mines 2013 Conference.  Short course only registration is available.

This one day short course will be divided between intrusion-related gold by Craig Hart, porphyry systems by Adi Maryono and Carlin deposits by Steve Garwin.

The development and classification of intrusion-related gold models provides the foundation for the descriptive characterization of these systems and presentations about their formation. Examples of geochemical and geophysical footprints will provide a foundation for the development of appropriate exploration methods for these systems. Emphasis will be on those systems in Alaska and Yukon that are best understood.

The porphyry deposit component will present key geological characteristics of porphyry copper-gold systems from district- to deposit-scale including descriptions of intrusions, alteration, copper sulphide mineralogy, iron-oxides, veining, lithocap and leached cap. The lecture presents proven mapping techniques and critical field observations that can be used as vectors to ore. An emphasis will be placed on the recognition of porphyry systems through overprinting retrograde alteration zones, beneath barren lithocaps and leached caps. Examples include deposits in Indonesia.

The Carlin deposit component will present the geology, styles of hydrothermal alteration and mineralization, geochemical expression and geophysical signature of Carlin-type gold deposits.  Examples include deposits and districts in Nevada, Southeast Asia, China and elsewhere. The course will focus on vectors to ore and successful methods that have been applied towards deposit discovery.

This course will be of interest to exploration- and mine- geologists who wish to learn more about the characteristics of these important gold and copper deposit types.

Presenters

Craig Hart is the Director of MDRU, the Mineral Deposit Research Unit at the University of British Columbia. His experience includes regional geological mapping, mineral deposit and regional metallogenic studies, plutonic systems, geochronology, and exploration targeting orogenic belts around the word. He is a major contributor to the development of intrusion-related gold models, is dedicated to graduate student research and training, and a recipient of the SEG Distinguished Lecturer (2011).

Adi Maryono has over 23 years of experience as an exploration geologist in SE Asia, Pakistan, Papua New Guinea, Solomon Islands and Australia. He has been involved in a number of discoveries and Tumpangpitu in East Java (Intrepid). He holds a B.Sc. degree in Geology from the University of Gadjah Mada, Indonesia and a M.Sc. degree in Mineral Exploration from Queen's University, Canada.

Steve Garwin has 25 years of experience as an exploration geologist in SE Asia, China, Papua New Guinea, Solomon Islands, Australia, the western USA, British Columbia, Mexico, Peru, Ecuador and Chile. He worked with Newmont Mining for ten years, including two years as Chief Geologist in Nevada. Steve is one of the leading authorities on epithermal, porphyry and Carlin-style fellow at the Centre for Exploration Targeting at the University of Western Australia since 2001.
