What is gold?

Gold, chemical symbol Au (from the Latin aurum meaning "shining dawn") and atomic number 79, is a precious metal. In its purest form, it is a bright, slightly reddish yellow, dense, soft, and malleable metal, highly valued for its extreme ductility, strong resistance to corrosion, lustrous beauty. Gold often occurs in free elemental (native) form, as nuggets or grains, in rocks, in veins, and as dust in the beds of rivers. Gold has been used since antiquity in the production of jewellery, coinage, sculpture, vessels and as a decoration for buildings, monuments and statues. Some gold artefacts discovered by archaeologists in the Eastern Mediterranean and Balkan peninsula are dated to around the 4th millennium BC. Varna Necropolis also is known as Varna Cemetery is a burial site, widely regarded as the location of the oldest known gold object artefacts have been discovered, dating back to between 4600-4200 BCE. In more recent times, gold has been also used in engineering, electronics, medicine and other fields.

Key Phrases

  • Lode Deposits
    • In nature, gold in the most occasions occurs in its native state, as a metal. These deposits, for the most part, comprised of little grains or minuscule particles of metallic gold embedded in solid rock. The encompassing rocks are often quartz or sulfide minerals, for example, pyrite. The natural gold itself is generally a combination containing around 10% silver.
  • Placer Deposits
    • A placer is any deposit of sand, rock, or other characteristic material that has amassed in a streambed, on a shoreline, or in residual alluvial deposits. Due to its high density, gold tends to gather and concentrate in placer deposits.

    The Cortez gold mine
     located 100km south-west of Elko (Lander County, Nevada) is currently the 9th largest gold mine in the world. The mine contains a gold reserve of nearly 15Moz (425 tonnes) including 2Moz of proven and 13Moz of probable gold reserves. Gold production from Cortez started in 1969. The mine employs both open-pit and underground mining methods. Cortez gold mine is owned and operated by Barrick Gold. As one of Barrick’s most promising ore bodies, the site is scheduled to receive $153 million from the company through 2020. This will help expand its underground mining capacity, allowing it to produce an additional 300,000 ounces per year.

    Canada

     is most famous for its Yukon Territory and the part it played in the Klondike Gold Rush of 1896. Gold was first discovered in Canada in 1823 along the Riviere Chaudiere in eastern Quebec.
    Canadian gold deposits are located along the Canadian Shield, in British Columbia and Nunavut, and on the island of Newfoundland. The Canadian Shield covers half of the land area of the country. Most of Canada's gold mines are located on the Shield, especially in Ontario, Quebec and British Columbia.

    Gold is mined in nine Canadian provinces and territories. There are several mines in operation. They include Eskay Creek Mine and Myra Falls Operation in British Columbia; Garson Mine and Stobie Mine in Ontario; Brunswick Mining Division in New Brunswick; Thompson Mill and Rice Lake Gold Mine in Manitoba; Mouska Mine and Sleeping Giant in Quebec; Canadian Malartic (Agnico Eagle and Yamana Gold), Quebec; and Meadowbank Gold Mine and Meliadine Agnico Eagle Gold Mine in Nunavut.

    Placer gold deposits

     in Canada are usually extracted from streams, creeks and rivers in Canada by amateur prospectors by panning and sluicing. Metal detecting for gold nuggets isn’t as common in Canada as it is in Australia and the USA, although some gold hunters have had success with it. Like Alaska, many of the best places to find gold in Canada are deep in wilderness areas.

    Gold in Central and South America

    Gold has been mined all throughout whole region of

    South America

    , from small-scale miners up to large commercial mining companies. From northern Mexico all the way to the southern tip of Chile, this is truly one of the richest gold-bearing areas on Earth. Some of the largest gold mines are placed on the continent, and there is still potential for future discoveries. Undoubtedly, there are millions of ounces of gold still yet to be found here.
    Whenever someone thinks about gold mining in South America they usually start of by thinking about prospecting in Peru, Chile and Brazil. Looking deeper in the subject we start to see that there is a lot of gold in Ecuador and Columbia. However very few people tend to look beyond that group of countries and because of that narrower view, many people miss out on great prospecting opportunities that take place in some of the other smaller less known countries as Guyana.

    Guyana is a one of the smaller South American countries that borders between Venezuela to the west, Suriname to the east and Brazil to the south. Guyana is very often called the "Land of Eldorado" because of the vast amounts of quanties of bauxite, manganeese, diamonds and gold along with other precious stones that are buried within the ground of this country. With gold prices now hitting record highs, many people from its coastal towns are heading into the country's interior to seek their fortune, either using artisanal methods or, if they can afford it, bringing in heavy dredging equipment. While most gold mining operations in the country are smaller alluvial/placer mines, there are larger operations that are open pit and underground also.

    Gold in Australia and Oceania

    Australia

     is the second largest producer of gold in the world. The great majority of the gold that is produced in Australia comes from large commercial gold mining operations. Most of the commercial gold mines in Australia are open-pit mine type, but some mining is also done underground. Western Australia has the largest number of commercial gold operations, with the rest scattered around the Northern Territory and the other states in Australia.
    Plenty of gold is found in Australia every year by smaller, non-commercial gold operations, individual prospectors and amateur nugget hunters. Australia become a much sought-after destination for prospectors during the gold rush of the 1800’s. Since then, significant amounts of gold are discovered in New South Wales, Victoria, Queensland, Tasmania and Western Australia.

    Boddington
     - The Newmont-operated Boddington gold mine located near Boddington, 75 miles southeast of Perth, Western Australia is the country’s largest gold mine. The mine contained a gold reserve of 11,6 Moz (328 tonnes) as of December 2017.
    The open-pit gold mine first commenced operations in 1987 by extracting the shallow oxide ores up to 70m deep below surface. It was brought under care and maintenance in 2001. Commercial production from the Boddington gold mine was restarted in 2009, with an expected mine life of up to 20 years. A project is being implemented to extend the mine life up to 2041 by exploiting additional gold resources identified in the low-grade hard rock ores below the previously mined pits.

In many countries of the EU, such as the United Kingdom, Romania, Greece, Slovakia, and Portugal, some gold mining projects are at the licensing stage. Geological exploration for gold deposits is ongoing also in other countries, such as France, Italy, Slovakia and Austria.
