The story
Hudson Bay Mining and Smelting Co.
The Flin Flon greenstone belt was discovered by David Collins, a local trapper, and shown to prospector Tom Creighton in 1915. It was named after Josiah Flintabbatey Flonatin, a character in The Sunless City. The first claim was registered in 1915.
In 1925, after unsuccessful attempts to develop the mine, Cornelius Vanderbilt Whitney (a member of the Whitney family of New York), along with Newmont Mining and Mining Corp of Canada, founded Hudson Bay Mining & Smelting (HBM&S), which acquired the Flin Flon property. The huge, high grade ore body required large amounts of hydro energy, was isolated, and copper production required a smelter, leading to delays in production. In June 1930, the mine, smelter, hydroelectric dam and railroad finally went into operation. In 1938, the company was listed on the New York Stock Exchange. The company supplied the United States with metals during World War II. In 1958, Hudbay opened its first mine in Snow Lake, 215 kilometres east of Flin Flon. Six years later, production began at Stall Lake Mine. In the 1960s, Anglo American plc, a South African mining company, invested in the company.
In the area near Flin Flon, the company started production at Anderson Lake in 1970 and discovered the Trout Lake deposit in 1974, which began production in 1982. It opened a concentrator at Snow Lake in 1979. In 1987, it discovered the Chisel North mine, which began production in 2001. In 1992, Hudbay closed its original Flin Flon mine; however, that same year, as a result of underground exploration, Hudbay discovered a substantial orebody that became its flagship 777 mine in Flin Flon; it went into development in 1999.
Hudbay Minerals
On December 21, 2004, OntZinc Corporation (formerly known as Pan American Resources) acquired HBM&S from Anglo American plc for C$316 million in cash and stock. The company was then renamed HudBay Minerals and was listed on the Toronto Stock Exchange.
In 2007, Hudbay located a significant zinc deposit near Snow Lake that became known as Lalor. The deposit also contained a large volume of gold, enough to support its own mine. Production began in 2012 and the mine officially opened in September 2014.
In August 2008, Hudbay acquired Skye Resources, owner of the Fenix Nickel Project in Guatemala, a substantial brownfield lateritic nickel mine and process plant that has been on care and maintenance since 1980, for US$460 million. Sky Resources was sold to Solway Group in 2011 for US$170 million.
In late 2008, the company entered into a merger agreement with Lundin Mining; at the time, Hudbay owned 20% of Lundin Mining. However, the proposed transaction failed to receive investor support due to the 2008 financial crisis and was terminated in February 2009; Hudbay sold its stake in Lundin in May 2009.
In 2008, shortly after the Lalor deposit discovery, the corporate head office was relocated to Toronto, Ontario from Winnipeg, Manitoba.
