Lundin Mining Announces Drill Program in Norrbotten,
Northern Sweden

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Nov. 4, 2004) -
(TSX:LUN)(Nya Marknaden:LUMI) Lundin Mining Corporation ("Lundin Mining"
or the "Company") is pleased to announce that a drilling program has
been completed on the Ailatis copper-gold target at the Company's
Norrbotten Project in northern Sweden. The Ailatis target is located
within the area of agreement with Anglo American Exploration BV and Rio
Tinto Mining and Exploration Ltd. ("Anglo-Rio").

The Ailatis target area is approximately 8 kilometers west of the
Rakkurijarvi target area where significant copper-gold mineralization
was encountered in a drilling program conducted earlier in the year (see
Lundin Mining news release dated April 5 and June 1, 2004).

Drilling on the Ailatis target commenced in early September, 2004 and
was completed in late October, 2004. Twenty-three drill holes totaling
2,317 meters were drilled to test a number of chargeablilty anomalies
within an area of four square kilometers where basal till samples of
bedrock indicate anomalous values in gold and copper. Underlying bedrock
consists of highly altered mafic volcanics, gabbro and conglomerate.
Numerous holes were drilled previously in the area by the Swedish
Geological Survey in 1990, the best of which intersected 17.3 meters
grading 0.88% copper(i).

All drill core was split, sampled and shipped to the preparation lab of
North Atlantic Natural Resources AB in Uppsala, Sweden. Samples were
subsequently shipped to ALS Chemex Labs in Vancouver, Canada for gold
and multi-element analysis. Results will be reported when available,
expected in late November. They will also be available on the Company's
website at www.lundinmining.com. The Qualified Person in charge of the
project is professional geologist Mr. Robert Lilljequist.

(i) Note: these are historical drill results reported before the
implementation of National Instrument 43-101.
