Yamana Gold Inc. is a Canadian company that owns and operates gold, silver and copper mines in Canada, Chile, Brazil and Argentina. Headquartered in Toronto, the company was founded in 1994 and became listed on the Toronto Stock Exchange in 1995, the New York Stock Exchange in 2007, and the London Stock Exchange in 2020. The company became a gold producer after its 2003 re-restructuring in which Peter Marrone took over as chief executive officer and it merged with Brazilian company Santa Elina Mines Corporation. The combined company was able to use Yamana's access to capital with Santa Elina development properties to bring the Chapada mine into production. From there the company combined with other TSX-listed companies RNC Gold, Desert Sun Mining, Viceroy Exploration, Northern Orion Resources, Meridian Gold, Osisko Mining and Extorre Gold Mines which each contributed either a producing mine or a development project that was able to come into commercial production. The company was acquired by Pan American Silver in March 2023. Wikipedia
