Konawaruk River
The Konawaruk River is a river in Potaro-Siparuni, Guyana. About 60 miles long, it is a tributary of the Essequibo River, joining it just south of the Potaro River mouth at . About two miles from the juncture at the Essequibo, is Temple Bar falls. Mining, especially for gold Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile me ..., was the primary industry along the river as early as 1900, and being mined by British Guiana Consolidated Enterprise Limited in the 1950s. In 2003, an assessment by United Development International "verified reserves of over 400,000 ounces of gold" in the claim encompassing the Konawaruk. Pollution from extraction processes, including the use of missile dredges, has had a severe effect on the ecology of the river and environmentalists have considered it "dead ...

Potaro-Siparuni
Potaro-Siparuni (Region 8) is a region of Guyana. Venezuela claims the majority of the Region located west of the Essequibo River as part of Guayana Esequiba. It borders the region of Cuyuni-Mazaruni to the north, the regions of Upper Demerara-Berbice and East Berbice-Corentyne to the east, the region of Upper Takutu-Upper Essequibo to the south and Brazil to the west. The main villages in the region are Campbelltown, Orinduik, Mahdia, Paramakatoi and Tumatumari. Population The Government of Guyana has administered three official censuses since the 1980 administrative reforms, in 1980, 1991 and 2002. In 2012, the population of Potaro-Siparuni was recorded at 10,190 people. Official census records for the population of Potaro-Siparuni are as follows: *2012 : 10,190 *2002 : 10,095 *1991 : 5,616 *1980 : 4,485 Communities (including name variants): *Arnik Village * Campbelltown *Itabac *Kamana Village *Kanapang Village * Kato (Kato Village, Karto) *Kopinang Mission *Mahdia * ...

Guyana
Guyana ( or ), officially the Cooperative Republic of Guyana, is a country on the northern mainland of South America. Guyana is an indigenous word which means "Land of Many Waters". The capital city is Georgetown. Guyana is bordered by the Atlantic Ocean to the north, Brazil to the south and southwest, Venezuela to the west, and Suriname to the east. With , Guyana is the third-smallest sovereign state by area in mainland South America after Uruguay and Suriname, and is the second-least populous sovereign state in South America after Suriname; it is also one of the least densely populated countries on Earth. It has a wide variety of natural habitats and very high biodiversity. The region known as "the Guianas" consists of the large shield landmass north of the Amazon River and east of the Orinoco River known as the "land of many waters". Nine indigenous tribes reside in Guyana: the Wai Wai, Macushi, Patamona, Lokono, Kalina, Wapishana, Pemon, Akawaio and Warao. Histo ...

Essequibo River
The Essequibo River (Spanish: ''Río Esequibo'' originally called by Alonso de Ojeda ''Río Dulce'') is the largest river in Guyana, and the largest river between the Orinoco and Amazon. Rising in the Acarai Mountains near the Brazil–Guyana border, the Essequibo flows to the north for through forest and savanna into the Atlantic Ocean. With a total drainage basin of and an average discharge of . Territory near the river is argued over by Venezuela and Guyana. Venezuela considers that the natural border according to the divortium aquarum that delimits the eastern margin of that country with the Cooperative Republic of Guyana is "by law", although due to the territorial dispute between the two countries for the sovereignty of Guayana Esequiba, it is "De facto administered and occupied for the most part by the former English colony of British Guiana, present-day Guyana. Geography The river runs through the Guianan moist forests ecoregion. The average annual rainfall in the catc ...

Potaro River
The Potaro River is a river in Guyana that runs from Mount Ayanganna area of the Pakaraima Mountains for approximately before flowing into the Essequibo River, Guyana's largest river. The renowned Kaieteur Falls is on the Potaro. Features Nine waterfalls are found on the Potaro River, most notable being Kaieteur Falls and Tumatumari Falls. Below Kaieteur Falls lie Amatuk Falls and Waratuk Falls. A 1930 Suspension bridge, the Garraway Stream Bridge crosses the river. As well, 'Two Islands' is found on the Potaro River. Minerals Placer gold and diamonds are extracted from the river in this mineral-rich area. Many thousands of ounces of placer gold have been recovered from the area's stream gravels, residual placers and saprolites. In the first half of the 20th century, small-scale artisanal miners, known as pork-knockers, recovered significant quantities of gem-quality diamonds from the area's rivers and streams. In fact, the two largest gem-quality diamonds recovered in G ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...

Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...

Missile Dredge
In military terminology, a missile is a guided airborne ranged weapon capable of self-propelled flight usually by a jet engine or rocket motor. Missiles are thus also called guided missiles or guided rockets (when a previously unguided rocket is made guided). Missiles have five system components: targeting, guidance system, flight system, engine and warhead. Missiles come in types adapted for different purposes: surface-to-surface and air-to-surface missiles (ballistic, cruise, anti-ship, anti-submarine, anti-tank, etc.), surface-to-air missiles (and anti-ballistic), air-to-air missiles, and anti-satellite weapons. Airborne explosive devices without propulsion are referred to as shells if fired by an artillery piece and bombs if dropped by an aircraft. Unguided jet- or rocket-propelled weapons are usually described as rocket artillery. Historically, the word ''missile'' referred to any projectile that is thrown, shot or propelled towards a target; this usage is still recog ...
