Summary Joint Short Course Activity HMTG”TOBA” ITM, GITMSC OF AAPG, and SM-IAGI ITM by Mr. Benny Alizar Amin Pulungan (Senior Geologist at PT. Agincourt Resources Gold Mine), Medan, Indonesia, March 26th, 2016:
Short Course that held on 26th March, 2016 at the class room at Institute Technology of Medan, Medaan, Indonesia that have a title “Eksploration Gold and Copper in Indonesia”, followed by 70 students Geology, Mining (ITM and ISTP), and lecturer from two department.The event that held by Executive Geology Institute Technology of Medan Student Chapter of American Association of Petroleum Geologists, HMTG”TOBA” ITM and also SM-IAGI ITM, this programme is held caused less knowledge about Eksploration Gold and Copper in Indonesia. In this event as speakers is Mr. Benny Alizar Amin Pulungan from PT. AGINCOURT RESOURCES GOLD MINE. This Event is at opens by Faculty Advisor of GITMSC OF AAPG is Ir. Lismawaty MT, with proudly, she is say thank’s for PT. Agincourt Resources Gold Mine on come In Institute Technology of Medan for delivery information in really and that bloom to Student Geology and mining so that increase know about mining.
Mineral exploration is the process of finding ores (commercially viable concentrations of minerals) to mine. Mineral exploration is a much more intensive, organized and professional form of mineral prospecting and, though it frequently uses the services of prospecting, the process of mineral exploration on the whole is much more involved. Gold prospecting is the act of searching for new gold deposits. Methods used vary with the type of deposit sought and the resources of the prospector. Although traditionally a commercial activity, in some developed countries placer gold prospecting has also become a popular outdoor recreation. Prospectors for hardrock, or lode gold deposits, can use many tools. It is done at the simplest level by surface examination of rock outcrops, looking for exposures of mineral veins, hydrothermal alteration, or rock types known to host gold deposits. Field tools may be nothing more than a rock hammer and hand lens. Hardrock gold deposits are more varied in mineralogy and geology than placer deposits, and prospecting methods can be very different for different types of deposits. As with placer gold, the sophistication of methods used to prospect for hardrock gold vary with the financial resources of the prospector. Most gold today is produced in large open-pit and deep underground mines. However, small-scale gold mining is still common, especially in third-world countries.
Copper is a chemical element with symbol Cu and atomic number 29. It is a soft, malleable and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a reddish-orange color. It is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys. Copper is essential to all living organisms as a trace dietary mineral because it is a key constituent of the respiratory enzyme complex cytochrome c oxidase. In molluscs and crustacea copper is a constituent of the blood pigment hemocyanin, which is replaced by the iron-complexed hemoglobin in fish and other vertebrates. The main areas where copper is found in humans are liver, muscle and bone. The mining sector has made a very significant contribution to the Indonesian economy over the past several decades and will continue to do so for decades to come. According to a Fraser Institute survey, Indonesia is ranked amongst the top six countries in the world in terms of geological prospectivity. Indonesia is the seventh largest producer of both gold and coal in the world and the second-largest gold producer in Asia. Following the 10-year exodus of junior mining companies from Indonesia after the 1997 Asian economic crisis, Southern Arc’s management saw a unique window of opportunity. Acting quickly with a regionally-experienced team, Southern Arc became the first Canadian junior exploration company since 1997 to return to Indonesia and established a portfolio of exploration properties on Indonesia’s Lombok and Sumbawa islands. Indonesia hosts numerous large mineral deposits, including Newmont’s Batu Hijau copper-gold mine and Freeport’s giant Grasberg copper-gold mine. Grasberg produced 1.22 billion pounds of copper and1.79 million ounces of gold in 2010, making it the world’s largest gold mine and third largest copper mine. Newmont’s Batu Hijau mine produced 542 million pounds of copper and 737,000 ounces of gold in 2010, providing jobs for around 7,000 people who work directly for the mine or for contractors retained by Newmont to operate at the mine site. The Batu Hijau mine is a significant contributor to the local and national economy in Indonesia. Newmont has also reported plans to develop its Elang copper-gold porphyry deposit which is reported to contain 25 million ounces of gold and 16 billion pounds copper (Newmont press release February 2011). East Elang is located 63 km east of the Batu Hijau mine and adjoins Southern Arc’s East Elang property. With decades of experience in Indonesian exploration and mining, Southern Arc’s management and directors provide an outstanding blend of experience and expertise to advance the company’s exploration and business objectives. Southern Arc’s management and directors bring a track record of achievements in international exploration, development, mining, engineering, company management, finance, acquisitions and administration.
This event can give a lot of opportunities for students to receive more knowledge and enhance their perception outside the classes about development mining and also training. We believe this program is important for those who want to be a geologist. It also give great opportunity to establish a good relationship among industry, AAPG, educational institution and students. Hopefully, this activity done well and will more knowledge to student about “Short Course about Eksploration Gold and Copper in Indonesia”, and get motivation or inspiration to can join in mining industry.
Support thank’s to AAPG, AAPG Asia Pacific Region, ITM, HMTG”TOBA”ITM, SM-IAGI ITM, and other.
