Kanichee Mine
The Kanichee Mine, also less commonly known as the Ajax Mine, is an abandoned base metal and precious metal mine, located in the Temagami region of northeastern Ontario, Canada. It is near the small unincorporated community of Temagami North, accessed by the Kanichee Mine Road from Highway 11. The Kanichee Mine zone has been explored and mined discontinuously from as early as 1910. During the 20th century, it operated and closed down at least three times, with the most recent being from 1973 to 1976. To date, the discontinuous operation of Kanichee Mine has produced 4.2 million pounds of metal. The Kanichee area is associated with an igneous intrusion that has been termed the Kanichee layered intrusive complex. This roughly oval-shaped intrusive complex is part of a volcanic belt characterized by felsic and mafic metavolcanic rocks called the Temagami Greenstone Belt. Kanichee is one of the three most notable mines in the volcanic belt, others include the Sherman Mine in Chambers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temagami, Ontario
Temagami, formerly spelled as Timagami, is a municipality in northeastern Ontario, Canada, in the Nipissing District with Lake Temagami at its heart. The Temagami region is known as ''n'Daki Menan'', the homeland of the area's First Nations community, most of whom are Anishinaabe (Ojibwe), living on Bear Island. The official name for this group is the Temagami First Nation. However, a larger group that includes these people, plus non-status residents and some non-residents is called the Teme-Augama Anishnabai. Some of the main tourist attractions within the community include old-growth red and white pine, Lake Temagami, Caribou Mountain, fishing, showings of Grey Owl from the 1930s, and over of canoe routes. It is also known as the staging point for cottage vacationing and wilderness canoeing trips on Lake Temagami, in Lady Evelyn-Smoothwater Provincial Park, and vast tracts of wilderness in the area. There are several outfitters here that cater to outdoor activity. The co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Belt
A volcanic belt is a large volcanically active region. Other terms are used for smaller areas of activity, such as volcanic fields. Volcanic belts are found above zones of unusually high temperature () where magma is created by partial melting of solid material in the Earth's crust and upper mantle. These areas usually form along tectonic plate boundaries at depths of . For example, volcanoes in Mexico and western North America are mostly in volcanic belts, such as the Trans-Mexican Volcanic Belt that extends from west to east across central-southern Mexico and the Northern Cordilleran Volcanic Province in western Canada. The deeply deformed and eroded remnants of ancient volcanic belts are found in volcanically inactive regions such as the Canadian Shield. It contains over 150 volcanic belts (now deformed and eroded down to nearly flat plains) that range from 600 to 1,200 million years old. These are zones of variably metamorphosed mafic to ultramafic volcanic sequences wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smelter
Smelting is a process of applying heat to ore, to extract a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including Silver mining#Ore processing, silver, iron-making, iron, copper extraction, copper, and other base metals. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. The reducing agent is commonly a fossil fuel source of carbon, such as coke (fuel), coke—or, in earlier times, charcoal. The oxygen in the ore binds to carbon at high temperatures due to the Chemical energy, lower potential energy of the bonds in carbon dioxide (). Smelting most prominently takes place in a blast furnace to produce pig iron, which is converted into steel. The carbon source acts as a chemical reactant to remove oxygen from the ore, yielding the purified metal Chemical element, element as a product. The carbon source is oxidized in two stage ...

Cuniptau Mines Limited
Cuniptau Mines (a combination of the symbols Cu, Ni, Pt and Au) was a Canadian mining company from 1933 to 1937. It was incorporated in December 1933 under the leadership of B. W. Watkins with its headquarters based in Toronto, Ontario. The company was engaged in development of the Cuniptau Mine, a polymetallic ore deposit in Strathy Township of Northeastern Ontario. In later years Cuniptau Mines also acquired the Alexo Mine property in Clergue and Dundonald townships of Cochrane District. History and operations Development of the Cuniptau Mine began in 1933 with the sinking of a shaft and underground drifting on the shaft level. This was followed by deepening of the shaft to , a new level established at , drifting, crosscutting and raising in 1934. Operations in 1935 were confined mostly to surface mineral exploration. In 1936, the smelter was rebuilt to test out the possibilities of making a suitable matte from the mined ore. High-grade quartz vein material from the Cunip ...

Shaft Mining
Shaft mining or shaft sinking is the action of excavating a mine shaft from the top down, where there is initially no access to the bottom. Shaft (civil engineering), Shallow shafts, typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining projects. Shaft sinking is one of the most difficult of all mine development methods: restricted space, gravity, groundwater and specialized procedures make the task quite formidable. Shafts may be sunk by conventional drill and blast or mechanised means. Historically, mine shaft sinking has been among the most dangerous of all the mining occupations and the preserve of mining contractors called sinker (mining), sinkers. Today shaft sinking contractors are concentrated in Canada, Germany, China and South Africa. The modern shaft sinking industry is gradually shifting further towards greater mechanisation. Recent innovations in the form of full-face shaft boring (akin to a v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trench
A trench is a type of excavation or in the ground that is generally deeper than it is wide (as opposed to a wider gully, or ditch), and narrow compared with its length (as opposed to a simple hole or pit). In geology, trenches result from erosion by rivers or by geological movement of tectonic plates. In civil engineering, trenches are often created to install underground utilities such as gas, water, power and communication lines. In construction, trenches are dug for foundations of buildings, retaining walls and dams, and for cut-and-cover construction of tunnels. In archaeology, the "trench method" is used for searching and excavating ancient ruins or to dig into strata of sedimented material. In geotechnical engineering, trenches serve for locating faults and investigating deep soil properties. In trench warfare, soldiers occupy trenches to protect them against weapons fire. Trenches are dug by use of manual tools such as shovels and pickaxes, or by heavy equipment such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Temagami
Lake Temagami, formerly spelled as Lake Timagami, is a lake in Nipissing District in northeastern Ontario, Canada, situated approximately 80 km north of North Bay. The lake's name comes from ''dimii-agamiing'' "tih-MEE-uh-guh-MEENG", which means "it is deep water by the shore" in the Ojibwa language. Geography The lake is irregularly shaped with long north, northeast and southwest arms, shorter northwest and south arms and several smaller bays. The town of Temagami is located at the end of the northeast arm of the lake. It extends almost 50 km from north to south and about 35 km from east to west. There are approximately 1,259 islands, the largest of which is Temagami Island. The lake's outflow is the Temagami River which in turn flows into the Sturgeon River. A number of peninsulas are associated with the lake, such as the McLean, Cynthia and Joan peninsulas, as well as Sand Point, which separates the Northwest Arm from the rest of the lake.

Temagami Island
Temagami Island, formerly spelt as Timagami Island, is an island in Lake Temagami in Northeastern Ontario, Canada. It is the largest island within the lake, with Bear Island coming second. The island has many hiking trails that lead into the old-growth forest that is a mix of large white and red pine trees. Temagami Mine, later known as Copperfields Mine, was a copper mine that opened on Temagami Island in 1954. It was considered to be the largest deposit of nearly pure chalcopyrite ever discovered in Canada. The mine closed in 1972.

Copperfields Mine
Copperfields Mine, originally known as Temagami Mine, is an abandoned copper and silver mine on Temagami Island in Lake Temagami, Ontario, Canada. The mine opened in 1955 and comprises both underground and surface workings within a sulfide ore body. Situated in Phyllis Township, the mine produced 34,000,000 dollars Canadian with 80 million pounds of copper, 230,028 ounces of silver and 13,271 ounces of gold. It was considered to be the largest deposit of nearly pure chalcopyrite ever discovered in Canada. A mill was not initially needed because the ore was 28% copper. The mine closed in 1972 and is now flooded by water. Ruins of the Copperfields mill are present as foundations. It is possible to find mineral specimens in the spoil heaps of the old mine, such as chalcopyrite, pyrite, bornite, malachite, dolomite, hessite, merenskyite, millerite, palladium, quartz and others. The Lake Temagami Access Road was created to ship ore from the mine site. Copper-nickel mineralization at th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sherman Mine
Sherman Mine is a closed open pit mine in Temagami, Ontario, Canada. It was a major producer of iron ore, starting production in 1968 and closing in 1990. Sherman was the largest open pit mine in Temagami, consisting of seven open pits known as the East Pit, South Pit, North Pit, West Pit and the Turtle Pits. The mine was discovered in the early part of the twentieth century, however interest was limited as a result of silver and gold discoveries in northeastern Ontario. While the Ontario government offered bounties to producers of iron ore, there was little interest in putting any iron mine into production as a result of cheaper Mesabi Range ores from the US and the Great Depression. It was only in the 1950s that Canadian steel producers started to investigate domestic supplies of iron ore. This would lead to the re-opening of the Moose Mountain Mine and development of the Adams, Sherman and Bruce Lake mines in Northern Ontario. The Sherman Mine operated in tandem with the Adams M ...

Temagami Greenstone Belt
The Temagami Greenstone Belt (TGB) is a small 2.7 billion year old greenstone belt in the Temagami region of Northeastern Ontario, Canada. It represents a feature of the Superior craton, an ancient and stable part of the Earth's lithosphere that forms the core of the North American continent and Canadian Shield. The belt is composed of metamorphosed volcanic rocks that range in composition from basalt to rhyolite. These form the east-northeast trend of the belt and are overlain by metamorphosed sedimentary rocks. They were created during several volcanic episodes involving a variety of eruptive styles ranging from passive lava eruptions to viscous explosive eruptions. Part of the Canadian Shield, the TGB contains some of the oldest known rocks on Earth. The belt is made up of a number of geologic features such as batholiths, stocks, dikes, volcanic complexes, layered intrusions and deformation zones. These are situated in several geographical townships in the municipality of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
