Great Panther Mining

Great Panther Mining Limited (formerly Great Panther Silver) is a Canadian company that owns and operates mines in Mexico and Brazil that produce gold, silver, zinc and lead. Headquartered in Vancouver, the company is listed on the Toronto Stock Exchange in Canada and the NYSE American in the United States. The company became a metal producer in 2006 after a re-restructuring in which Robert Archer took over as Chief Executive Officer and acquired several dormant mines in Mexico. After the company brought both the Topia and Guanajuato mines back into production, its stock graduated to the Toronto Stock Exchange. The company acquired other mineral interests and merged with TSXV-listed Cangold in 2015 but only acquired its third mine after merging with ASX-listed Beadell Resources in 2019 for its Tucano mine in Brazil.
History.
The company that would become Great Panther Mining was founded in 1965 as a private company called Lodestar Mines Ltd, prospecting emeralds in Zimbabwe. It became a public company, as Lodestar Energy Inc, with its initial public offering on June 18, 1980, on the Vancouver Stock Exchange. It underwent several name changes, mergers and acquisitions and pursued several business interests throughout the 1980s and 1990s, including oil and gas development in Oklahoma, agriculture as Controlled Environmental Farming International Ltd, baby bassinets as New Age Ventures and oil again, this time in California and Thailand, as Great Panther Inc. 
The company re-organized again in 2003-04 to become Great Panther Resources Limited, with a new CEO, Robert Archer, to pursue the development of various mineral rights in Mexico. Among other interests, it acquired the Guanajuato Mine complex and the Mexican mining company Minera Mexicana el Rosario SA de CV for its dormant Topia Mine. They brought those former mines back into production so that in 2006 they produced 730 tonnes of zinc, 616 tonnes lead, 313,484 oz of silver and 1,394 oz of gold. With this production, in November 2006, the company's stock graduated to the Toronto Stock Exchange from the TSX Venture Exchange. In 2010, when the company changed its name to Great Panther Silver they produced 1,534,957 oz silver along with over a thousand tonnes of both zinc and lead and, subsequently, in 2011, their stock became cross-listed on the NYSE Amex Equities Exchange. While the Topia and Guanajuato mines would remain their only operating mines until 2019, they pursued other mineral interests, such as the El Horcon silver-gold project in Jalisco, Mexico and the Coricancha gold-siver project in Peru. In 2015, Great Panther Silver purchased TSXV-listed Cangold for its the Guadalupe de los Reyes gold-silver project in Sinaloa, Mexico, in an all-share deal worth $1.7 million. The company has been challenged with several deaths at its mine sites. In 2014 a trespasser was killed by guards, in 2016 a worker was killed while operating an underground loader, both at the Guanajuato complex, and in 2019 two more workers were killed in a work place accidents.
The company added a third mine to their operations with the 2019 acquisition of Australian Securities Exchange-listed Beadell Resources Limited for their Tucano gold mine in Brazil. The all-stock deal, valued at $105 million, gave Beadell shareholders 38% of the combined company.
 With work on mining gold and other metals making up more of their operations, the company changed its name from Great Panther Silver to Great Panther Mining, and then in 2020, hired a new CEO, Rob Henderson, and replaced much of its board of directors.
