Hudbay Minerals

Hudson Bay Mining and Smelting Co.

The Flin Flon orebody was discovered by David Collins, a local trapper, and shown to prospector Tom Creighton in 1914. The first claim was registered in 1915. It took more than a dozen years to bring the mine into production because the huge, high grade ore body required large amounts of hydro energy, was isolated, and copper production required a smelter.

In 1927, Cornelius Vanderbilt Whitney , along with Newmont Mining Corp and Mining Corp of Canada Ltd., founded Hudson Bay Mining & Smelting , which took over controlling interest in the Flin Flon property. By 1930, the mine, smelter, hydroelectric dam and railroad were in full operation. Eight years later, the company was listed on the New York Stock Exchange under the symbol HBM. 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, Hudbay also gained a new major investor, Anglo America, a South African mining company.Throughout the 1970s and 1980s, Hudbay continued to mine and explore in and around Flin Flon and Snow Lake, discovering new deposits, such as Trout Lake and Chisel North, and starting production at new mines, like Anderson Lake. After more than 60 years in operation, in 1992, Hudbay closed its original Flin Flon mine; however, one year later, as a result of underground exploration, Hudbay discovered a substantial orebody that would become its flagship 777 mine in Flin Flon.

Hudbay Minerals Inc.

On December 21, 2004, OntZinc Corporation acquired HBM&S for C$316 million from Anglo American plc. The purchase was financed by a public offering of C$143.8 million of equity and the issue of US$175 million of debt. The company then changed its name to Hudbay Minerals Inc.

Hudbay was also listed on the TSX under the symbol HBM.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, large enough to support its own mine. Initial production began in 2012 and the mine officially opened in September 2014.In 2008, shortly after the Lalor deposit recovery, the corporate head office relocated to Toronto, Ontario from Winnipeg, Manitoba.In March 2011, Hudbay acquired Norsemont Mining Inc. and its Constancia copper mine in Peru for $520 million. Construction on the mine began in August 2012 and commercial production commenced in April 2015.That same year, Hudbay acquired the New Britannia mill from QMX Gold in Manitoba. Plans to refurbish the mill were shared by Hudbay in February 2019 as part of its updated plan to double gold production at Lalor.Hudbay bought Augusta Resource Corporation in June 2014 and with it, acquired its Rosemont copper project in Arizona. Hudbay received all permits required to build and operate the mine, with the final record of decision received in June 2017 and 404 Water Permit received in March 2019. Following 10 years of consultations and studies, in August 2019 the U.S. District Court for the District of Arizona issued a ruling in the lawsuits challenging the U.S. Forest Service's issuance of the Final Record of Decision. As per the ruling, Hudbay was barred from proceeding with construction of the Rosemont project. As of 2020, Hudbay is in the process of appealing the decision.In January 2018, Hudbay acquired mining properties near its Constancia mine in southern Peru. In December of the same year, the company announced the acquisition of all remaining issued and outstanding common shares of Mason Resources. This acquisition gave Hudbay ownership of the Ann Mason project in Nevada.In March 2019, the company confirmed plans to shut down its operations in Flin Flon in the second quarter of 2022.On February 18, 2020, the community of Chilloroya formally approved a surface rights agreement with Hudbay for the Pampacancha satellite deposit located near the Constancia mine in Peru.In May 2020, Hudbay announced that it would be spending $115 million to refurbish its New Britannia Mill, expected to be completed in 2022.

Pan American Resources Inc.

Founded as Pan American Resources Inc., the company first went public on the Montreal Exchange under the symbol PAN in the 3rd quarter of 1996.Pan American acquired all of OntZinc Corporation on March 12, 2002. Subsequently, the company renamed itself OntZinc Corporation on August 15, 2002. Upon acquisition of HBMS, the company renamed itself Hudbay Minerals Inc. on December 24, 2004.On August 26, 2008, Hudbay Minerals announced the completion of a business combination with Skye Resources Inc. Skye Resources was renamed HMI Nickel, and was a subsidiary of Hudbay Minerals until Hudbay divested of the project through the sale of its interest in CGN to the Solway Group in September 2011.In November 2008, Hudbay Minerals and Lundin Mining announced an agreement to merge. However, in February 2009, after a ruling by the Ontario Securities Commission that Hudbay must allow its shareholders to vote on the plan, the companies announced that the deal had been terminated after realizing it was unlikely to win shareholder support.On January 9, 2009, Hudbay Minerals suspended operations at Chisel North Mine in Snow Lake, Manitoba. The mine stopped producing in late February 2009, due to falling zinc metal prices and increased costs, and restarted operations in 2010.
