38 SEG NEWSLETTER No 90 • JULY 2012 Institute of Geology and Geophysics, Chinese Academy of Sciences Student Chapter STUDENT NEWS Field Trip to Jiaodong Peninsula The Institute of Geology and Geophysics, Chinese Academy of Sciences (IGGCAS) SEG student chapter organized its first field trip (May 6–10), highlighted by a visit to two giant Au deposits, the Jiaojia The underground lounge at Jiao gold mine. From left to right: Mingjian Cao, Mingjun Tian, Yu Zhang, Zhiyuan Li, Engineer from Mining Company, Kuifeng Yang, Yachun Cai. and Linglong deposits, which are disseminated-type and quartz-vein gold deposits, respectively. Additionally, the Sanshandao gold deposit and granites of Jiaojia and Linglong were investigated along the way. The main purpose of this trip was to help students to understand the geological features of disseminated-type and quartz-vein gold deposits and differences between these types of deposits, and to broaden their understanding of hydrothermal deposits. The field trip was led by Dr. Kuifeng Yang, associate professor at IGGCAS. Five Ph.D. candidate student chapter Several members of the group pose during an investigation of Jiaojia granite.

Engi - neers from Jiao Mining Company hosted the group and gave an introduction to the Jiao deposit, and also led the group on a tour of the underground orebody. 1 Leicester Student Chapter Second Annual SEG Student Chapter Symposium Following the success of its first sympo - sium held in 2011, the Leicester student chapter hosted the Second Annual SEG Student Chapter Symposium in February, this year on the theme of sustainable development. Leicester welcomed students from chapters all over the UK to the Symposium, which focused on sustainable development in mineral exploration and how companies need to consider sociopolitical and environmental issues when undertaking exploration and mining projects. Keynote speaker Sarah Gordon, from AngloAmerican, gave an exciting talk entitled “Sustainable Mining: Reality or Spin.” Other guest speakers at the Symposium included Jack Lunnon and Andy Rodgers from MICROMINE, John Menzies from CMI Capital, and Daniel Smith from the University of Leicester, who presented the beginning of his afternoon workshop with a talk on “Sustaining Supply and Sustainable Development.” Mark Davis also attended as a guest of the chapter and represented SRK Exploration Services. During the first of two workshops, students worked in groups to identify a deposit using hand specimens, stream Students in the exploration workshop had the opportunity to analyze data and make decisions about exploration during project simulations. sediment, and soil geochemistry data. They also constructed geological maps and cross sections of the project area, and made recommendations for the next stages of exploration, gaining experience and skills in exploration techniques and decision making. Guest speakers acted as consultants throughout the exercise. Daniel Smith led the second interactive workshop, with groups having to extract vital information from various governmental groups including the Ministry of Mines, Commerce, and Environment, to determine whether “Cobrespuccia Mining Ltd.” would be allowed to mine their deposit in what was designed as a notoriously corrupt example Republic, an exercise designed to mimic the kind of situation they could come across in industry. The event was generously sponsored by the Society of Economic Geologists, ArcelorMittal UK, Barrick, SRK Explora - tion Services, MICROMINE and our in - dustrial sponsor, Helio Resources Corp.

Field Trip News Richard Scrivener took a group on a tour of historic and future mining sites around the Dartmoor area of Devon that first visited the world-class Hemerdon tungsten mine, owned by Wolf Minerals. The final stop on the trip was the historic Birch Tor and Vitifer Sn mine, where the earliest workings are not known, but it is supposed that the veins were located by the medieval tin streamers in tracing placer deposits to their source. 1 Contributed by Kristen Morgan
JULY 2012 • No 90 SEG NEWSLETTER 39 Dalhousie University Student Chapter Field Trip to the PotashCorp and Xstrata Mines On February 2, five students from the Dalhousie University SEG student chapter embarked on a two-day trip from Halifax, Nova Scotia, to visit the Potash Corp potash mine in Sussex, NB, followed by a visit to the Pb-Zn mine outside Bathurst, NB. The trip was undertaken in conjunction with a group of 15 engineering students and two instructors from the Mineral and Resource Engineer - ing Department at DAL; this is a yearly trip for the engineering students and we were very pleased to be invited along. While much of trip was geared more toward the engineering aspects of mining, both mines had geologists on staff. Our trip began at 3 a.m. in order to time our arrival at Sussex with a shift of workers going down the mine shaft. The entire group was allowed underground A group of students, geologists, and engineers pose underground at PotashCorp in Sussex, NB. in a single shift and were taken on a guided truck tour of the different areas of the mine, where we were allowed to leave the vehicles and explore a bit. The following morning we again had an early start at the Xstrata-owned Brunswick mine, arriving at 7 a.m. to coincide with a scheduled shift change. The mine is currently in a winding-down phase with plans to cease major operations in early 2013 after 49 years of production in one of the largest underground mining operations in the world. We thank the SEG and the DAL Earth Sciences department who provided us with significant funding in order to undertake this. We also thank Dr. Don Jones and Dr. John Hill, from the DAL Mineral and Resource Engineering department, the leaders of the trip, for planning and coordinating trip activities, as well as the engineering students who attended. Finally, we thank PotashCorp and Xstrata for arranging these guided tours and allowing us to visit. 1 Contributed by Kyle Landry SEG www.segweb.org STUDENT NEWS The University of Nevada, Reno Student Chapter Field Trip to Turkey The University of Nevada, Reno student chapter recently completed an 11-day field trip through western Turkey. The focus of the trip was on exploring a relatively new and diverse metallogenic province that before the early 1990s was not open to foreign companies. We visited three producing mines and two exploration projects with a variety of deposit types that included porphyry Cu-Au, porphyry Au, and epithermal Au-Ag. We also visited several historic sites, including the ancient city of Troy and the Roman ruins at Pergamon. After flying to Istanbul and enjoying a day of sightseeing the group took a ferry across the Sea of Marmara to the town of Bandirma, and then drove west to Çanakkale, on the banks of the Dar - danelles. The next morning we headed southeast toward Teck Resources’ Halilağa porphyry Cu-Au exploration project. We were greeted by the staff and taken to several outcrops to look at the leached capping of the porphyry system. When we returned the staff had laid out four complete drill holes so that we could see the classic porphyry alteration zoning and mineralization of the deposit. Our next stop was down the coast of the Aegean to Bergama. After the standard Turkish breakfast of olives, salami, yogurt, and bread, we headed just outside of town to the Ovacık gold mine. Field trip participants tour Kişladağ, Tüprag’s porphyry-Au system in Uşak, Turkey. Ovacık is a low-sulfidation epithermal system and was the first gold mine in the region to be discovered by modern exploration techniques. After leaving Ovacık we headed back into Bergama to visit the Roman ruins at Pergamon. Next, we headed off to the Efemçukuru low-sulfidation epithermal deposit owned by the Turkish subsidiary of Eldorado Gold, Tüprag. Our next tour was the Au porphyry system Kişladağ, which is located about 1 hour southwest of the town of Uşak. Also owned by Tüprag, Kişladağ is the largest gold mine in Turkey, with an annual production of ~250,000 oz. Mineralization is hosted within a set of four nested alkali porphyritic intrusions that cut a series of quartz latite lava flows and volcaniclastics. Next, we drove northeast toward the Akarca project, a low-sulfidation epithermal system owned by Eurasian Minerals and Centera Gold. The deposit is located within Miocene to Pliocene basin sediments which overlie Paleozoic schists, limestones, and Paleocene granites. We thank our sponsors and industry participants who covered the student costs and made it possible for us to go on this amazing trip. 1 Contributed by Tyler Baril
