Boliden’s Myra Falls mine now sold

Boliden and listed Canadian mining company Breakwater Resources Ltd (Breakwater) have signed a final transfer agreement whereby Boliden is selling its wholly owned Canadian subsidiary, Boliden Westmin () Limited (BWCL), which owns the mine at Myra Falls. Boliden is to receive 18 million newly issued Breakwater shares whose market value1 corresponds to around SEK 42 million.

In addition to the shares, Boliden will also receive 5 million options with a redemption price of CAD 1.00 and a term ending on 27 January 2009. Boliden is expected to make a small capital gain on the sale that is due to be reported during the third quarter of 2004. Jan Johansson will be elected to the board of Breakwater.

Boliden’s current guarantees to the authorities in British Columbia regarding Myra Falls will remain in force for a period of one year.
