20 SEG NEWSLETTER No 90 • JULY 2012 SEG NEWS 2012 Distinguished Lecturer Dan Wood—and Distinguished Guests Left, Dan Wood (SEG 2009 F), SEG 2012 Distinguished Lecturer, speaks to students at James Cook University about careers in geology. During his recent visits, Dan also spoke at the University of Papua New Guinea (above). In attendance were the Deputy Vice-Chancellor of UPNG (a mathematician) as well as the Director of the Papua New Guinea Geological Survey. Over two weeks this spring, SEG held the inaugural courses in its “Field Methods in Economic Geology” training program. Participants came from around the globe to attend the courses, held at the Littleton, Colorado, headquarters course center. Both courses were fully booked. Sixteen volunteers from industry and academia donated considerable time and energy in giving lectures, organizing hands-on exercises, and mentoring the participants. During the first week, “Exploration and Drilling” provided an introduction to drilling, mining, and mineral processing methods for geoscientists new to economic geology. Participants were introduced to the conceptual framework and the basic techniques employed in exploration and mining. The course in - cluded hands-on opportunities to practice logging, sampling, and interpreting RC drilling results and drill core. Partic - ipants particularly benefitted from the high instructor-to-student ratios, the mentoring given by course instructors, and exposure to “tried-and-true” as well as state-of-the-art exploration techniques. During the second week, “Mineral Exploration Methods” was designed for recently hired professionals seeking to *SEG Education and Training Committee, Program Coordinator Field Methods in Economic Geology, I and II Littleton, Colorado · May–June 2012 Contributed by ELIZABETH HOLLEY* (SEG 2010) and KEN PAUL (SEG 1992 F) enrich their understanding of the concepts and techniques integral to mineral exploration. Course topics included ore deposit formation, analytical techniques and quality control, geochemical and geophysical techniques for mineral exploration, and the integration of data sets to generate exploration targets. For participants, this was a chance to rapidly gain needed exploration knowledge in a week. The two spring courses were an overall success: 80% of the participants would recommend these classes to a friend. Next year’s course will retain the most effective components as well as improvements generated by participant feedback. The classroom component will be condensed into a single, six-day course, entitled “Practical Methods in Economic Geology.” This course will target geoscientists with 0 to 3 years of experience in industry, as well as those seeking exposure to a wider range of deposit styles and exploration methods. Featured will be introductions Participants review core-logging techniques. to exploration and analytical and drilling techniques within the conceptual framework of ore deposit genesis. More emphasis will be given to handson exercises and breakout sessions so that attendees can practice applying concepts, with the same mentoring and high instructor-to-student ratios as in this year’s courses. The field component of the training curriculum, “Field Methods in Economic Geology: Mapping,” will take place in Arizona for the first time in early December 2012. Registration will open in September. We look forward to seeing you there! 1
JULY 2012 • No 90 SEG NEWSLETTER 21 SIMEXMIN 2012: The 5th Brazilian Symposium on Mineral Exploration Ouro Preto, Brazil · May 20–23, 2012 Contributed by ALVARO P. CRÓSTA (SEG 2008 F) SEG NEWS The 5 th Brazilian Symposium on Mineral Exploration (SIMEXMIN 2012, http://www.adimb.com.br/simexmin20 12/English ) was held in the old mining town of Ouro Preto, in the Iron Quad - rangle of Minas Gerais state, Brazil, on May 20 to 23. The conference was promoted by the Agency for the Technolog - ical Development of the Brazilian Mineral Industry (ADIMB), and copromoted by SEG. More than 1,000 participants attended the event, which covered a variety of themes: government policies for the Brazilian mining sector; recent exploration and discoveries of base and precious metals; Brazilian corporate exploration programs; metallogeny of the Brazilian, Canadian, and African shields; world commodities market; Tapajós and Xingu gold provinces; potential of rare earths, including vanadium, chromium, thallium, and tantalum; new exploration techniques; new deposits and largescale iron projects in Brazil; new worldclass mineral deposits; metallogenetic periods and phases of Brazilian ore provinces. The SEG organized a technical session and a short course as part SIMEXMIN. The session “Base and Precious Metals: New Exploration and Discoveries” was chaired by Alvaro Crósta (SEG) and Francisco I. (Chico) de Azevedo (Gold- Fields) with the following program: Canahuire Au-Cu-Ag Deposit, Peru - Chico de Azevedo (Gold Fields) Discovery and Development of the Caspiche Au-Cu Deposit, Maricunga Dis - trict, Chile - Justin Tol man (Exeter Resources) Discovery of Colosa Gold-Rich Porphyry Deposit, Cajamarca, Colombia - Timoleon Garzon (AngloGold Ashanti) Neoarchaen and Palaeoproterozoic Ni- Cu-EGP, Cr, Fe-Ti-V–bearing Magmatic Ore Systems of the Sao Francisco Craton - Reinaldo Brito (CPRM-Brazilian Geological Survey) Recent Advances in Genetic Concepts for Sedimentary-Hosted Copper Mineraliza - tion - Alexander Brown (École Poly - technique de Montreal) SEG members and student members pause during networking for a group photo.

Characteristics and Exploration Criteria for Orogenic Gold - Richard Goldfarb (USGS). The SEG-sponsored short course, “Sedimentary-Hosted Strati form Copper and Related Mineraliza-tion,” was given by Alex Brown (École Polytechnique de Montreal) on May 24 and 25 and had full attendance. SEG Vice-President for South America, Alvaro Crósta, organized a session with Brazilian geology students and academics to promote SEG s student programs and activities, as well as the establishment of new student chapters. It was attended by 30 students and academics from several Brazilian universities, who learned about the advantages offered by the Society to student chapters and their members. The number of student chapters has increased considerably in Brazil in the last few years, from two to six. Representatives from these chapters benefitted from financial support provided by SEG and ADIMB to attend SIMEXMIN and SEG s short course. The SEG booth attracted great attention during the event, with 30 students and professionals signing up for SEG membership. With this addition, Brazil’s membership has had a significant increase, nearly 150% since 2009, making Brazil the 2 nd largest SEG member community in South America. 1
