Lundin Mining Reaches Agreement in Principle to Sell 
Zinkgruvan Silver Production to Silver Wheaton

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Nov. 15, 2004) - Lundin 
Mining Corporation (TSX:LUN)(Nya Marknaden:LUMI) ("Lundin Mining" or the 
"Company") is pleased to announce that it has reached an agreement in 
principle with Chap Mercantile Inc. (to be re-named "Silver Wheaton") 
whereby Lundin Mining will sell all of its silver production from the 
Zinkgruvan mine in Sweden to Silver Wheaton in consideration for an 
upfront cash payment of US$50 million, 30 million Silver Wheaton shares, 
and 30 million whole share purchase warrants (worth in aggregate 
approximately US$80M), plus a per ounce payment at a price equal to the 
lesser of (a) US$3.90 (subject to a consumer price adjustment after 
three years) and (b) the then prevailing market price per ounce of 
silver as quoted on the London Bullion Market Association. Each warrant 
is exercisable at C$0.80 into one Silver Wheaton common share and 
expires on August 5, 2009.

Lundin Mining has agreed to deliver a minimum of 40 million ounces of 
silver to Silver Wheaton over a 25-year period. The Zinkgruvan zinc, 
lead and silver mine is expected to produce approximately 2 million 
ounces of silver per year in addition to 130 million pounds (59,000 
metric tonnes) of zinc and 70 million pounds (32,000 metric tonnes) of 
lead annually at low cash costs. If at the end of the 25-year period, 
Lundin Mining has not delivered the agreed 40 million ounces, then it 
has agreed to pay to Silver Wheaton US$1.00 per ounce of silver not 
delivered.

Lukas H. Lundin, Chairman of the Board of Lundin Mining, comments, "This 
is an excellent deal for the Company since we realize the value of the 
silver production at Zinkgruvan, while at the same time retaining all 
base metal exposure. The proceeds from this transaction will form the 
foundation for Lundin Mining's future growth plans."

Closing of the transaction is subject to execution of definitive 
agreements and receipt of all regulatory approvals and third-party 
consents, including acceptance by the Toronto Stock Exchange. It is 
expected that the closing of this transaction will occur by mid-December 
2004.

Macquarie is acting as financial advisor to Lundin Mining in connection
