Kongsberg Silver Mines
The silver mines of Kongsberg, in Buskerud county in Norway, constitute the largest mining field in Norway, with over 80 different mines. It was the largest pre-industrial working place in Norway, with over 4,000 workers at its peak in the 1770s and supplied over 10% of the gross national product of the Danish–Norwegian union during its 335-year-long history: over 450,000 man-years were expended in the production.
Kayelekera mine
Kayelekera uranium mine is an open cast uranium mine 52 kilometers west of the regional administrative and commercial centre Karonga in Malawi, Africa and is the country's largest mine. Kayelekera is owned 100% by Paladin (Africa) Limited (PAL), an 85% subsidiary of Australian and Canadian listed Paladin Energy and in July 2009, Paladin issued 15% of the equity in Paladin (Africa) Ltd to the Government of Malawi under the terms of the Mining Development Agreement signed between PAL and the Government in February 2007. The mine was officially opened on 17 April 2009 by the then Malawian president Bingu wa Mutharika. As of 2014, the mine is in care and maintenance mode owing to a depressed uranium market. While in production, the mine exported containers of uranium oxide via the port of Walvis Bay. The mine has not been profitable for its operators and has met opposition from organisations and individuals concerned about the mine's tax concessions, operation, adherence to law and regulation and its potential impacts on human and environmental safety.
