El Mochito Mine
El Mochito mine is an underground zinc and silver mine in Honduras that is owned by Ascendant Resources. The mine is located near the municipality of Las Vegas in northwest section Honduras. At approximately northeast of the mine, the closest major city is San Pedro Sula, which also acts as the commercial centre of the country. History The deposit was discovered in 1938. The Rosario Mining Company purchased the property in 1943 and began production in 1948. American Pacific Mining Corporation purchased the property in September 1987, and in March 1990, Breakwater Resources acquired American Pacific and the mine. In August 2011, Nyrstar successfully completed its acquisition of Breakwater Resources. On December 20, 2016 the mine was acquired by the Canadian firm Morumbi Resources, which renamed itself to Ascendant Resources effective December 21, 2016.

Underground Mining (hard Rock)
Underground hard-rock mining refers to various underground mining techniques used to excavate "hard" minerals, usually those containing metals, such as ore containing gold, silver, iron, copper, zinc, nickel, tin, and lead. It also involves the same techniques used to excavate ores of gems, such as diamonds and rubies. Soft-rock mining refers to the excavation of softer minerals, such as salt, coal, and oil sands. Mine access Underground access Accessing underground ore can be achieved via a decline (ramp), inclined vertical shaft or adit. *Declines can be a spiral tunnel which circles either the flank of the deposit or circles around the deposit. The decline begins with a box cut, which is the portal to the surface. Depending on the amount of overburden and quality of bedrock, a galvanized steel culvert may be required for safety purposes. They may also be started into the wall of an open cut mine. *Shafts are vertical excavations sunk adjacent to an ore body. Shafts are s ...

Zinc
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.The elements are from different metal groups. See periodic table. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It ...

Silver
Silver is a chemical element with the Symbol (chemistry), symbol Ag (from the Latin ', derived from the Proto-Indo-European wikt:Reconstruction:Proto-Indo-European/h₂erǵ-, ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of th ... [...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 ...

Honduras
Honduras, officially the Republic of Honduras, is a country in Central America. The republic of Honduras is bordered to the west by Guatemala, to the southwest by El Salvador, to the southeast by Nicaragua, to the south by the Pacific Ocean at the Gulf of Fonseca, and to the north by the Gulf of Honduras, a large inlet of the Caribbean Sea. Its capital and largest city is Tegucigalpa. Honduras was home to several important Mesoamerican cultures, most notably the Maya, before the Spanish Colonization in the sixteenth century. The Spanish introduced Catholicism and the now predominant Spanish language, along with numerous customs that have blended with the indigenous culture. Honduras became independent in 1821 and has since been a republic, although it has consistently endured much social strife and political instability, and remains one of the poorest countries in the Western Hemisphere. In 1960, the northern part of what was the Mosquito Coast was transferred from Nicara ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The New York and Honduras Rosario Mining Company (NYHRMC), known as Rosario Mining Company, was an American-owned corporation that owned and operated the Rosario mine, a gold and silver producer in central Honduras and Nicaragua. History 1880 The President of Honduras, Marco Aurelio Soto, offered companies that invested in the mine in San Juancinto a 20-year exemption from all taxes. In 1880, Julius Valentine, of New York City founded the New York and Honduras Rosario Mining Company, exchanging 50% of the Company's stock for the mining rights of the El Rosario deposits at San Juancito which were owned by Soto.

Nanisivik Mine
Nanisivik Mine was a zinc-lead mine in the company town of Nanisivik, Nunavut, north of the Arctic Circle on Baffin Island. It was Canada's first mine in the Arctic. The mine first opened on 15 October 1976 and permanently closed in September 2002 due to low metal prices and declining resources. Mine reclamation began in April 2003. It was one of the most northerly mines in the world. The mine was served by a port and dock located about north. It was used for shipping concentrate from the site, and receiving supplies. It is currently used by the Canadian Coast Guard for training and is intended to become Nanisivik Naval Facility.
