Highland Valley Copper
The Highland Valley Copper mine is the largest open-pit copper mine in Canada, located near Logan Lake, British Columbia. It is an amalgamation of three historic mining operations: Bethlehem (later Valley Copper), Lornex and Highmont. History Early years The earliest roots of the Bethlehem mining operations began when the Jersey zone was staked and bonded to a French syndicate . This claim changed hands several times until finally in October 1954 when the Huestis-Reynolds-McLallen Syndicate sponsored a prospective examination covering 100 claims including Jersey and surrounding zones. Copper was known to occur in the Cascade Mountains near Princeton as the productive mines of Allenby in 1914 had shown. On the strength of this, prospectors searched for other deposits in the region. These they found north of Merritt and east of Ashcroft at Logan Lake at the Jersey zone. 1950s-1960s In February 1960, Bethlehem Copper Corporation made an agreement with the Japanese group Sumito ...

Thompson Plateau
The Thompson Plateau forms the southern portion of the Interior Plateau of British Columbia, Canada, lying to the west of Okanagan Lake, south of the Thompson River and east of (although never adjoining it) the Fraser River. At its most southern point the plateau is squeezed by the mountainous terrain of the Cascade Range abutting closer to the Okanagan Valley. Its southwestern edge abuts the Canadian Cascades portion of that extensive range, more or less following the line of the Similkameen River, its tributary the Tulameen River, and a series of passes from the area of Tulameen, British Columbia to the confluence of the Thompson River with the Nicoamen River, a few kilometres (miles) east of Lytton, British Columbia, which is in the Fraser Canyon. Its northeastern edge runs approximately from the city of Vernon, British Columbia through the valley of Monte Creek to the junction of the same name just east of the city of Kamloops. Northeast of that line is the Shuswap Highland. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sumitomo
The is one of the largest Japanese ''keiretsu'', or business groups, founded by Masatomo Sumitomo (1585-1652) around 1615 during the early Edo period. History The Sumitomo Group traces its roots to a bookshop in Kyoto founded circa 1615 by Masatomo Sumitomo, a former Buddhist monk. Even today management of the group is guided by his "Founder's Precepts", written in the 17th century. Copper refining made the company famous. Riemon Soga, Masatomo Sumitomo's brother-in-law, learned Western methods of copper refining. In 1590 he established a smelting business, ''Izumiya'', literally meaning "spring shop". Riemon perfected techniques that allowed the extraction of silver from copper ore, something Japanese technology had not previously accomplished. The smelting and smithing business was moved from Kyoto to Osaka by the late 17th century. Soga passed control of the company to his son Tomomochi who managed its transformation into a major trading house during the Edo period. Sumitom ...

Open-pit Mines
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburden is relatively thin or the material of interest is structurally unsuitable for tunnelling (as would be the case for cinder, sand, and gravel). In contrast, minerals that have been found underground but are difficult to retrieve due to hard rock, can be reached using a form of underground mining. To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting eac ...

Molybdenum Mines In Canada
Molybdenum is a chemical element with the symbol Mo and atomic number 42 which is located in period 5 and group 6. The name is from Neo-Latin ''molybdaenum'', which is based on Ancient Greek ', meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of other metals) in 1778 by Carl Wilhelm Scheele. The metal was first isolated in 1781 by Peter Jacob Hjelm. Molybdenum does not occur naturally as a free metal on Earth; it is found only in various oxidation states in minerals. The free element, a silvery metal with a grey cast, has the sixth-highest melting point of any element. It readily forms hard, stable carbides in alloys, and for this reason most of the world production of the element (about 80%) is used in steel alloys, including high-strength alloys and superalloys. Most molybdenum compounds have low solubility ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper Mines In British Columbia
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 ...

Gibraltar Mine
The Gibraltar Mine is a Canadian copper mine operated by Taseko Mines near McLeese Lake in British Columbia, Canada. It is the second largest Open-pit mining, open-pit mine in Canada and the fourth largest in North America. The mine is the largest employer in the Cariboo_Regional_District, Cariboo region. Gibraltar was originally opened by Placer Development Ltd. of Vancouver in 1972. The property was sold in 1996 to Westmin Resources which closed the mine in 1998.

Port Of Vancouver
The Port of Vancouver is the largest port in Canada and the fourth largest in North America by tonnes of cargo, facilitating trade between Canada and more than 170 world economies. The port is managed by the Vancouver Fraser Port Authority, which was created in 2008 as an amalgamation of the former Port of Vancouver, the North Fraser Port Authority, and the Fraser River Port Authority. It is the principal authority for shipping and port-related land and sea use in the Metro Vancouver region. History Predecessors Prior to the formation of the new authority, there were three separate port authorities in the Metro Vancouver region: the Port of Vancouver, which was the largest port in Canada; the Fraser River Port Authority; and the North Fraser Port Authority. The Vancouver Port Authority was responsible for the Port of Vancouver, which was the largest port in Canada and the Pacific Northwest. The port had 25 major terminals. The port first began operations with the opening o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ashcroft, British Columbia
Ashcroft ( 2016 population: 1,558) is a village in the Thompson Country of the Interior of British Columbia, Canada. It is downstream from the west end of Kamloops Lake, at the confluence of the Bonaparte and Thompson Rivers, and is in the Thompson-Nicola Regional District. Ashcroft's downtown is on the east side of the Thompson River, although the municipal boundaries straddle the river, with housing and the town's hospital and recreation complex on the west bank. It is something of a "twin" to nearby Cache Creek, which unlike Ashcroft is on the major highway. History Ashcroft was named after the nearby Ashcroft Manor on Ashcroft Ranch founded in the 1860s, during the Cariboo Gold Rush, by two English brothers named Clement Francis Cornwall and Henry Pennant Cornwall, who emigrated to Canada from Ashcroft, at Newington Bagpath in Gloucestershire. The brothers had originally come in search of gold; however, on hearing stories from failed gold searchers they decided to found t ...
