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: - -------------------------------------------------------------------------------- TONNES ZN CU AU AG (000S) (%) (%) G/T G/T ================================================================================ Proven and Probable Reserves 7,747 6.3 1.2 1.2 40 Measured and Indicated Resources* 10,388 7.8 1.4 1.7 56 Inferred Resources 2,284 4.9 1.1 1.4 57 ================================================================================ *Measured and Indicated Resources include Proven and Probable Reserves.
