Rio Algom was a mining corporation that was purchased by Billiton in 2000 and is now part of BHP.
It operated many uranium mines and mills in the Elliot Lake region of Ontario, Canada, including the Lacnor Mine, Nordic Mine, Panel Mine, Pronto Mine, Quirke Mine, Milliken Mine, Stanleigh Mine, and the Spanish-American Mine. These operated from the 1950s to the 1990s. [1]
It got ownership of a uranium mill in the Ambrosia Lake region of New Mexico when it purchased the Quivira Mining Corporation from Kerr-McGee in 1989. The mill had only been active from 1958-1985. However from 1989-2002 it produced uranium from recovered mine-water. [2] [3] [4]
The 2017 performance of Rio Algom, who own nine decommissioned uranium mines at Elliot Lake, was described as "below expectations" by the Canadian Nuclear Safety Commission. [5] The commission reported radium releases above limits at the Stanleigh effluent treatment plant, prompting engineering work plus increased site monitoring by Rio Algom. [5]
Rio Algom bought the Quivira Mining Corporation (a subsidiary of Kerr-McGee) in 1989. [3]
Rio Algom was bought by Billiton in 2000. [6] [1] [2] [3] [4]

Elliot Lake is a city in Algoma District, Ontario, Canada. It is north of Lake Huron, midway between the cities of Sudbury and Sault Ste. Marie in the Northern Ontario region. Once dubbed the "uranium capital of the world," Elliot Lake has since diversified to a hub for forest harvesting, mine reclamation expertise, and advanced manufacturing. Elliot Lake is now known as a place for affordable retirement living, waterfront cottage lots and as a four-season destination.
The Kerr-McGee Corporation, founded in 1929, was an American energy company involved in oil exploration, production of crude oil, natural gas, perchlorate and uranium mining and milling in various countries. On June 23, 2006, Anadarko Petroleum acquired Kerr-McGee in an all-cash transaction totaling $16.5 billion plus $2.6 billion in debt and all operations moved from their base in Oklahoma, United States.
Denison Mines Corp. is a Canadian uranium exploration, development, and production company. Founded by Stephen B. Roman, and best known for its uranium mining in Blind River and Elliot Lake, it later diversified into coal, potash, and other projects.
Uranium mining in New Mexico was a significant industry from the early 1950s until the early 1980s. Although New Mexico has the second largest identified uranium ore reserves of any state in the United States, no uranium ore has been mined in New Mexico since 1998.

For many years, North America was the largest exporter of uranium ore in the world and has been a major world producer since demand for uranium developed. In 2009 Kazakhstan took over top spot, relegating Canada to second. 20% of the world's primary uranium production came from mines in Canada in 2009. 14.5% of the world production came from one mine, McArthur River. Currently the only producing area in Canada is northern Saskatchewan, although other areas have had active mines in the past.
