Arctic Russia has a huge potential for the production of minerals. For example, 91% of natural gas production and 80% of Russia's explored reserves of explored natural gas are located in the Arctic. The Arctic also contains 90% of its offshore reserves of hydrocarbons. According to Burakova (2005), the estimated value of Arctic minerals was $1.5-2 trillion. In addition, there were 25 mines operating in Arctic Russia in 2006 (Anon 2006a). The majority of these mines were Ni-Cu mines but Sn, U and phosphate were also mined.
