Troy Mine
The Troy Mine is a silver and copper producer near Troy, Montana, in Lincoln County. It operated between 1981 and 1993, when it was closed. It was re-opened in 2005 to be used as a training site for the Rock Creek Mine, located nearby in Sanders County, Montana. The Troy Mine produced about 1.25-1.4Moz silver per annum as of 2012; 159,121 pounds of copper and 27,053 pounds of silver between November 2014 and January 2015. A miner was killed in a cave-in in 2007. Rockslides and rock falls closed the mine in December 2012. It re-opened in September 2014. In January 2015, Revett Minerals Inc. announced that the Troy Mine would be "placed on care and maintenance" due to low minerals prices. In March 2015, it was announced that Hecla Mining Hecla Mining is a gold, silver and other precious metals mining company based in Coeur d'Alene, Idaho. Founded in 1891, is the second-largest mining company that produces silver in the country. This area is known as the Silver Valley (Ida ...

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] |
Copper
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 ...

Troy, Montana
Troy is a city in Lincoln County, Montana, United States. The population was 797 at the 2020 census. It lies at the lowest elevation of any settlement in Montana. The town is on U.S. Route 2, near Montana Highway 56, in the Kootenai River gorge by the Kootenai National Forest. Originally inhabited by the Kutenai, Salish, and Piegan Blackfeet tribes, the area was settled by miners in the 1880s. Troy was registered as a town in 1892 and grew quickly after the Great Northern Railway built a freight station there, leading to a boom in workers, miners, their families, and associates. The area narrowly missed wildfire damage in 1910 and expanded its services throughout the following years, though its population would drop due to a series of misfortunes in the late 1920s before rebounding in the following decades. Troy suffered from the area's contamination from nearby vermiculite mines contaminated with particularly fragile asbestos, leading to the town's inclusion in the United ...

Missoulian
The ''Missoulian'' is a daily newspaper printed in Missoula, Montana, United States. The newspaper has been owned by Lee Enterprises since 1959. The ''Missoulian'' is the largest published newspaper in Western Montana, and is distributed throughout the city of Missoula, and most of Western Montana. History Early years The ''Missoulian'' was established as the ''Missoula and Cedar Creek Pioneer'' on September 15, 1870, by the Magee Brothers and I. H. Morrison, under the Montana Publishing Company. Though strictly conservative politically, the paper was never intended to advance any particular "clique or party". Slightly less than a year after removing "Cedar Creek" from the name, the paper's name was trimmed to simply ''The Pioneer'' in November 1871, with W. J. McCormick, a prominent Montana politician and father of future Congressman Washington J. McCormick, as publisher. It served as a Democratic paper that was devoted to reporting on the development of western Montana. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hecla Mining
Hecla Mining is a gold, silver and other precious metals mining company based in Coeur d'Alene, Idaho. Founded in 1891, is the second-largest mining company that produces silver in the country. This area is known as the Silver Valley (Idaho). In 1983, this entire area was designated as a Superfund site by the Environmental Protection Agency, because of land, water, and air contamination resulting from a century of mostly unregulated silver and gold mining. History James Toner filed the Hecla claim on 5 May 1885. He passed on the claim to A.P. Horton, who sold it to George W. Hardesty and Simon Healey. Patrick (Patsy) Clark owned the claim outright by 1 July 1891. On 29 Sept. 1891, Clark formed the Hecla Mining Company with Albert Gross and Charles Kipp. On 14 Oct. 1891, the company was incorporated in Idaho by Clark, Charles Kipp, John A. Finch, Amasa B. (Mace) Campbell, John Dorsey, Healey and Hardesty, and 500,000 shares issued. By 1897, the mine had three tunnels and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geography Of Lincoln County, Montana
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
