Viceroyalty Of New Spain
New Spain, officially the Viceroyalty of New Spain ( es, Virreinato de Nueva España, ), or Kingdom of New Spain, was an integral territorial entity of the Spanish Empire, established by Habsburg Spain during the Spanish colonization of the Americas and having its capital in Mexico City. Its jurisdiction comprised a huge area that included what is now Mexico, the Western and Southwestern United States (from California to Louisiana and parts of Wyoming, but also Florida) in North America; Central America, the Caribbean, very northern parts of South America, and several territorial Pacific Ocean archipelagos. After the 1521 Spanish conquest of the Aztec empire, conqueror Hernán Cortés named the territory New Spain, and established the new capital, Mexico City, on the site of the Tenochtitlan, the capital of the Mexica (Aztec) Empire. Central Mexico became the base of expeditions of exploration and conquest, expanding the territory claimed by the Spanish Empire. With the politica ...

World Heritage Site
A World Heritage Site is a landmark or area with legal protection by an international convention administered by the United Nations Educational, Scientific and Cultural Organization (UNESCO). World Heritage Sites are designated by UNESCO for having cultural, historical, scientific or other form of significance. The sites are judged to contain " cultural and natural heritage around the world considered to be of outstanding value to humanity". To be selected, a World Heritage Site must be a somehow unique landmark which is geographically and historically identifiable and has special cultural or physical significance. For example, World Heritage Sites might be ancient ruins or historical structures, buildings, cities, deserts, forests, islands, lakes, monuments, mountains, or wilderness areas. A World Heritage Site may signify a remarkable accomplishment of humanity, and serve as evidence of our intellectual history on the planet, or it might be a place of great natural beauty. A ...

Explosion 1
An explosion is a rapid expansion in volume associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Supersonic explosions created by high explosives are known as detonations and travel through shock waves. Subsonic explosions are created by low explosives through a slower combustion process known as deflagration. Causes Explosions can occur in nature due to a large influx of energy. Most natural explosions arise from volcanic or stellar processes of various sorts. Explosive volcanic eruptions occur when magma rises from below, it has very dissolved gas in it. The reduction of pressure as the magma rises and causes the gas to bubble out of solution, resulting in a rapid increase in volume. Explosions also occur as a result of impact events and in phenomena such as hydrothermal explosions (also due to volcanic processes). Explosions can also occur outside of Earth in the universe in events suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Pit Mine
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 ...

Minera San Xavier
Minera San Xavier is a subsidiary of the Canadian company New Gold Inc. that operates a gold and silver mine near Cerro de San Pedro, a municipality of San Luis Potosí just 12 kilometers away from the capital city of the state. The city of San Luis Potosí was founded after gold was discovered in the hills near Cerro de San Pedro in the 15th century. The company has defied legal resolutions against its operation by arranging economically with the Mexican ecological authority, the Secretariat of the Environment and Natural Resources (Secretaría de Medio Ambiente y Recursos Naturales, Semarnat), pushing them to disregard ecological research done by some independent institutions and to instead accept most other independent as well as company-funded and government required studies. Continuous internal and external monitoring of mining activities has not produced any evidence of contamination to date. On 5 February 2007, Pro San Luis Ecológico, A.C., filed a submission before the C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Gold Inc
New Gold Inc. is a Canadian mining company that owns and operates the New Afton gold-silver-copper mine in British Columbia and the Rainy River gold-silver mine in Ontario, Canada. Through a Mexican subsidiary company, they also own the Cerro San Pedro gold-silver mine in San Luis Potosí, Mexico, which ceased operation in 2017. While New Gold was founded in 1980 for the purposes of mineral exploration, the company became a mine operator with its merger of Peak Gold and Metallica Resources in 2008. A fourth company, Western Goldfields, joined in 2009. Together they operated the Peak mine in Australia and Mesquite Mine in California but sold both in 2018. Headquartered in Toronto, shares of the company are traded on the Toronto Stock Exchange and NYSE American.

Metallica Resources
Metallica Resources Inc. was a Canadian-based mineral and gold mining company. Metallica Resources was a publicly held Canadian mineral exploration and development company with a geographic focus in the Americas. The company had an ownership interest in a gold project at Cerro de San Pedro Mexico. This project generated legal challenges and concerted opposition by local citizens and organizations across Mexico and North America. The concerns were that the open-pit cyanide leach-pit process used by the project would produce irreparable harm to the environment and historical patrimony of this region in Mexico. Over the years, Mexican courts suspended or revoked various permits for Metallica's Cerro de San Pedro project. There were fourteen cases before the Mexican courts awaiting resolution. The Cerro de San Pedro case was also reviewed by the Commission for Environmental Cooperation (CEC). In addition, the company had a significant copper-gold project in Chile. Metallica's corporate ...

Bufa Hill
Bufa Hill or El Cerro de la Bufa is a hill found east of historic downtown Zacatecas City, Zacatecas, Mexico, of historic and cultural significance in the Zacatecas state. Name The origin of Bufa Hill's name is disputed. What is, perhaps, the best-known version of the tale says that the hill was christened ''Bufa'' by Juan de Tolosa. ''Bufa'' is a word that originated from Aragonese, meaning ''pig bladder'', which was used to describe the unique shape of the hill. History Pre-Hispanic period Bufa Hill, which lies to the east of historic downtown Zacatecas City, is 2,610 meters above sea level. The mountain served as a home to several Aridoamerican tribes, from whence the city Zacatecas received its name. The Chichimecan tribes that inhabited the Zacatecan area were the Caxcanes, Guachichiles, Guamares Irritilas, Huicholes, Tecuexes, Teules, Tepehuanes, Coras, y Zacatecas. The Zacatecas tribe was considered to be one of the most important. Thus, not only did the city of Zaca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
