Gold is a chemical element with the symbol Au and atomic number 79, making it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental (native) form, as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver, naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium.
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. 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.

The City of Victor is a Statutory City in Teller County, Colorado, United States. Gold was discovered in Victor in the late 19th century, an omen of the future of the town. With Cripple Creek, the mining district became the second largest gold mining district in the country and realized approximately $10 billion of mined gold in 2010 dollars. It reached its peak around the turn of the century when there were about 18,000 residents in the town. Depleted ore in mines, labor strife and the exodus of miners during World War I caused a steep decline in the city's economy, from which it has never recovered. The population was 397 at the 2010 census. There is a resumed mining effort on Battle Mountain.
Gold mining is the extraction of gold resources by mining. Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning. However, with the expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation. In the 20th and 21st centuries, most volume of mining was done by large corporations, however the value of gold has led to millions of small, artisanal miners in many parts of the Global South.

Mining in Australia has long been a significant primary sector industry and contributor to the Australian economy by providing export income, royalty payments and employment. Historically, mining booms have also encouraged population growth via immigration to Australia, particularly the gold rushes of the 1850s. Many different ores, gems and minerals have been mined in the past and a wide variety are still mined throughout the country.
Mining in Iran is still under development, yet the country is one of the most important mineral producers in the world, ranked among 15 major mineral-rich countries, holding some 68 types of minerals, 37 billion tonnes of proven reserves and more than 57 billion tonnes of potential reserves worth $770 billion in 2014. Mineral production contributes only 0.6 per cent to the country's GDP. Add other mining-related industries and this figure increases to just four per cent (2005). Many factors have contributed to this, namely lack of suitable infrastructure, legal barriers, exploration difficulties, and government control.
Mining in South Africa was once the main driving force behind the history and development of Africa's most advanced and richest economy. Large-scale and profitable mining started with the discovery of a diamond on the banks of the Orange River in 1867 by Erasmus Jacobs and the subsequent discovery and exploitation of the Kimberley pipes a few years later. Gold rushes to Pilgrim's Rest and Barberton were precursors to the biggest discovery of all, the Main Reef/Main Reef Leader on Gerhardus Oosthuizen's farm Langlaagte, Portion C, in 1886, the Witwatersrand Gold Rush and the subsequent rapid development of the gold field there, the biggest of them all.
There are different methods by which gold mining companies are ranked. One is by their annual production. Another is by their cash cost per ounce, that is, how much money it costs them to mine the gold. Since gold prices are the same everywhere, companies with lower costs per ounce make more profit. The most common method lists by market capitalization which considers the total value of capital holdings by that company. Also considered when comparing companies is their market capitalization per ounce of gold equivalent which takes the market value and total reserves and resources for each company as well as the price of gold into consideration. The figures for each company can be used to determine the value the stock market gives to each company's reserves on an ounce to ounce basis.
