Bougainville Copper Mine
The Panguna mine is a large copper mine located in the Autonomous Region of Bougainville, in the east of Papua New Guinea. Panguna represents one of the largest copper reserves in Papua New Guinea and in the world, having an estimated reserve of one billion tonnes of ore copper and twelve million ounces of gold. The mine has been closed since 1989 and has ceased all production. History The discovery of vast copper ore deposits in Bougainville's Crown Prince Range led to the establishment of the copper mine in 1969 by Bougainville Copper Ltd, a subsidiary of the Australian company Conzinc Rio Tinto of Australia. The mine began production in 1972, with the support of the Papua New Guinea National Government as a 20% shareholder. In contrast to this, the Bougainvilleans received 0.5–1.25% share of the total profit. The site was at the time the world's largest open-pit copper/gold mine, generating 12% of PNG's GDP and over 45% of the nation's export revenue. The mine caused deva ...

Autonomous Region Of Bougainville
Bougainville ( ; ; Tok Pisin: ''Bogenvil''), officially the Autonomous Region of Bougainville (Tok Pisin: ''Otonomos Region bilong Bogenvil''), is an autonomous region in Papua New Guinea. The largest island is Bougainville Island, while the region also includes Buka Island and a number of outlying islands and atolls. The interim capital is Buka, although this is considered temporary, with the capital likely to move. One potential location is Arawa, the previous capital. In 2011, the region had an estimated population of 250,000 people. The lingua franca of Bougainville is Tok Pisin, while a variety of Austronesian and non-Austronesian languages are also spoken. The region includes several Polynesian outliers where Polynesian languages are spoken. Geographically the islands of Bougainville and Buka are part of the Solomon Islands archipelago, but are politically separate from the independent country of Solomon Islands. Historically the region was known as the North Solomons. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flying Fox
''Pteropus'' (suborder Yinpterochiroptera) is a genus of megabats which are among the largest bats in the world. They are commonly known as fruit bats or flying foxes, among other colloquial names. They live in South Asia, Southeast Asia, Australia, East Africa, and some oceanic islands in the Indian and Pacific Oceans. There are at least 60 extant species in the genus. Flying foxes eat fruit and other plant matter, and occasionally consume insects as well. They locate resources with their keen sense of smell. Most, but not all, are nocturnal. They navigate with keen eyesight, as they cannot echolocate. They have long life spans and low reproductive outputs, with females of most species producing only one offspring per year. Their slow life history makes their populations vulnerable to threats such as overhunting, culling, and natural disasters. Six flying fox species have been made extinct in modern times by overhunting. Flying foxes are often persecuted for their real or ...

Copper Mines In Papua New Guinea
Copper is a chemical element with the symbol Cu (from la, cuprum) 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 pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form (native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create bronze, c. 350 ...

History Of Bougainville
Bougainville, an autonomous region of Papua New Guinea (PNG), has been inhabited by humans for at least 29,000 years, according to artefacts found in Kilu Cave on Buka Island. The region is named after Bougainville Island, the largest island of the Solomon Islands archipelago, but also contains a number of smaller islands. The first arrivals in Bougainville were ethnically Australo-Melanesian, related to Papuans and Aboriginal Australians. Around 3,000 years ago, Austronesians associated with the Lapita culture also settled on the islands, bringing agriculture and pottery. Present-day Bougainvilleans are descended from a mixture of the two populations, and both Austronesian and non-Austronesian languages are spoken to this day. In 1616, Dutch explorers Willem Schouten and Jacob Le Maire became the first Europeans to sight the islands. The main island was named after French admiral Louis Antoine de Bougainville, who reached it in 1768. The German Empire placed Bougainville under ...

Overburden
In mining, overburden (also called waste or spoil) is the material that lies above an area that lends itself to economical exploitation, such as the rock, soil, and ecosystem that lies above a coal seam or ore body. Overburden is distinct from tailings, the material that remains after economically valuable components have been extracted from the generally finely milled ore. Overburden is removed during surface mining, but is typically not contaminated with toxic components. Overburden may also be used to restore an exhausted mining site during reclamation. Interburden is material that lies between two areas of economic interest, such as the material separating coal seams within strata.Peng, Syd S. (1986) ''Coal Mine Ground Control'' (2nd edition), Wiley, New York, page 303, Analogous uses Overburden is also used for all soil and ancillary material above the bedrock horizon in a given area. By analogy, overburden is also used to describe the soil and other material that lies ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Shovel
A power shovel (also stripping shovel or front shovel or electric mining shovel or electric rope shovel) is a bucket-equipped machine, usually electrically powered, used for digging and loading earth or fragmented rock and for mineral extraction. Power shovels are a type of rope/cable excavator, where the digging arm is controlled and powered by winches and steel ropes, rather than hydraulics like in the more common hydraulic excavators. Basic parts of a power shovel include the track system, cabin, cables, rack, stick, boom foot-pin, saddle block, boom, boom point sheaves and bucket. The size of bucket varies from 0.73 to 53 cubic meters. Design Power shovels normally consist of a revolving deck with a power plant, drive and control mechanisms, usually a counterweight, and a front attachment, such as a crane ("boom") which supports a handle ("dipper" or "dipper stick") with a digger ("bucket") at the end. The term "dipper" is also sometimes used to refer to the handle and digge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papua New Guinea Defence Force
The Papua New Guinea Defence Force (PNGDF) is the military organisation responsible for the defence of Papua New Guinea. It originated from the Australian Army land forces of the territory of Papua New Guinea before independence, coming into being in January 1973 and having its antecedents in the Pacific Islands Regiment. The PNGDF is a small force, numbering around 2,500 personnel, and consists of a Land Element, an Air Element and a Maritime Element. It is a joint force tasked with defending Papua New Guinea and its territories against external attack, as well as having secondary functions including national-building and internal security tasks. Defence accounts for less than 2% of GDP, while also receiving significant assistance and training support from Australia, New Zealand, the United States, and other nations. The Defence White Paper 2013 has ambitious plans to increase the force to 5,000 personnel and double defence spending to 3% by 2017 and by 2030 have 10,000 personne ...

Bougainville Conflict
The Bougainville conflict, also known as the Bougainville Civil War, was a multi-layered armed conflict fought from 1988 to 1998 in the North Solomons Province of Papua New Guinea (PNG) between PNG and the secessionist forces of the Bougainville Revolutionary Army (BRA), and between the BRA and other armed groups on Bougainville. The conflict was described by Bougainvillean President John Momis as the largest conflict in Oceania since the end of World War II in 1945, with an estimated 15,000–20,000 Bougainvilleans dead, although lower estimates place the toll at around 1,000–2,000. Hostilities concluded under the Bougainville Peace Agreement in 1998. The national (PNG) government agreed to the founding of the Autonomous Bougainville Government and to certain rights and authorities which the autonomous government would have over what became known as Bougainville Province, which includes outlying small islands in addition to Bougainville Island itself.

Bougainville Revolutionary Army
The Bougainville Revolutionary Army (BRA) was a secessionist group formed in 1988 by Bougainvilleans seeking independence from Papua New Guinea (PNG). The leader of the BRA was Francis Ona who led the BRA against the Papua New Guinea Defence Force during the violent 10 year conflict. Not all BRA members agreed to the Peace Treaty and boycotted it, and have held out in an official no-go zone, protected by members of the Meekamui Defence Force, currently commanded by Moses Pepino. BRA leaders argued that Bougainville is ethnically part of the Solomon Islands and has not profited from the extensive mining that has occurred on the island. In 1989, BRA leaders proclaimed Bougainville independent from PNG and established the Autonomous Bougainville Government (ABG). As a result, fighting between the BRA and the PNG Defence Force, with support from Australia, escalated. In January 1991, the Honiara Declaration [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francis Ona
Francis Ona (c. 1953 – 24 July 2005) was a Bougainville secessionist leader who led an uprising against the Government of Papua New Guinea as part of the Bougainville Civil War. He and his followers were concerned about the environmental and social effects of the operation of the Panguna mine by Bougainville Copper, a subsidiary of Rio Tinto Group. On 17 May 1990, Ona declared the independence of the Republic of Me'ekamui."The Bougainville independence referendum: Assessing the risks and challenges before, during and after the referendum" by Jo Woodbury January 2015; Commonwealth of Australia It was not recognised internationally. In May 2004 Ona proclaimed himself "King of Me'ekamui." While resisting the peace process and 2005 elections, Ona mostly stayed in a safe haven, where his BRA forces controlled territory. He died of malaria in his village. Secessionist leader Ona was at one time employed by Bougainville Copper at the mine, but he became increasingly critical of its ...
