NEWS RELEASE

                BREAKWATER SIGNS DEFINITIVE AGREEMENT TO ACQUIRE
                  BOLIDEN WESTMIN (CANADA) LTD. FROM BOLIDEN AB

July 8, 2004 ... (BWR - TSX) BREAKWATER RESOURCES LTD. is pleased to announce
that it has concluded a definitive agreement with Boliden AB of Stockholm,
Sweden to acquire 100% of the shares of Boliden Westmin (Canada) Ltd. ("BWCL")
which owns, amongst other things, 100% of the Myra Falls zinc, copper, gold and
silver mine located on Vancouver Island, BC.

To purchase all of the shares of BWCL, Breakwater will issue to Boliden 18
million shares, with a value of approximately $7.5 million, and 5 million
warrants exerciseable at $1.00 per share and expiring January 27, 2009.

Management of Breakwater anticipates that, on a pro-forma basis, the acquisition
of BWCL will provide the following benefits to its shareholders.

o    Be accretive to Breakwater's EPS and CFPS, metal production and ore
     reserves.

o    Result in the proportion of gross sales revenue derived from the sale of
     copper concentrates increasing from 3% to 14% at current metal prices.

o    Result in the proportion of gross sales revenue derived from the sale of
     zinc concentrates decreasing from approximately 80% to 71% at current metal
     prices.

o    Increase Breakwater's overall size and position on the list of the world's
     zinc concentrate producers.

o    Add an additional mine with a minimum mine life of seven years, with a high
     probability of twelve years' mine life.

o    Increase Breakwater's zinc production by 68% over the period 2004 to 2010.

o    Increase Breakwater's copper, gold and silver production by 367%, 139%, and
     98% respectively.



o    Increase Breakwater's net revenues by 85% over the period 2004 to 2010.

o    Place Breakwater in a very favourable position for product delivery to its
     valued Asian customers.

As part of the transaction, Breakwater will assume environmental liabilities of
approximately $21.5 million. However, Boliden is required to maintain the posted
environmental Letters of Credit for a period of one year, after which time
Breakwater is required to retire Boliden's obligation in this regard.

In addition to the Myra Falls mine other assets that will remain in BWCL
include, but are not limited to, a convertible debenture of Taseko Mines Limited
(TKO) with $17 million outstanding, 11.3 million shares of Expatriate Resources
Ltd., which owns a zinc property in the Yukon, and some other minor share
holdings in Eastmain Resources Inc., Majestic Gold Corp., Thor Exploration Ltd.,
E-Energy Ventures Inc., Caribbean Resources and Bret Resources.

The President and Chief Executive Officer of New Boliden, Mr. Jan Johansson,
will join the Board of Directors of BWR.

The closing is expected to take place the third week of July, and in any event,
no later than August 13, 2004, following which Breakwater will immediately take
over the management of the Myra Falls mine. A senior executive of Breakwater has
been on site for the past several weeks, working closely with local management
and preparing for an orderly transition.

Breakwater has commenced metallurgical testing of the ores in order to finalize
the design of a possible new mill flow sheet that would incorporate the recovery
of lead from the ores and provide an additional revenue source from lead
concentrate. It is anticipated that this circuit change will also result in an
improvement in the quality of the copper concentrate produced at the mine and
thus further increase revenue.

Mr. Torben Jensen, P.Eng., Breakwater's qualified person, in conjunction with
qualified persons from BWCL, estimates the Mineral Reserves and Resources for
the Myra Falls mine as of December 31, 2003 to be as shown in the following
table:
