SEC FILE: 029704 TSE SYMBOL: PFG AND DAYTON MINING CORPORATION TSE, AMEX SYMBOL: DAY JANUARY 9, 2002 - 09:47 EST Pacific Rim and Dayton Mining Propose Merger VANCOUVER, BRITISH COLUMBIA--Pacific Rim Mining Corp. ("Pacific Rim") and Dayton Mining Corporation ("Dayton") are pleased to announce the approval by their Boards of Directors of an amalgamation of the companies, subject to shareholder and regulatory approval. Under the amalgamation Dayton shareholders will receive 1.760 common shares of Pacific Rim in exchange for each common share of Dayton, resulting in Dayton and Pacific Rim shareholders comprising 70% and 30% of the merged company respectively. After the transaction, the merged company will have approximately 78,276,794 shares outstanding. Fairness opinions regarding the amalgamation will be provided by Haywood Securities on behalf of Pacific Rim and Dundee Securities Corporation on behalf of Dayton. Tom Shrake and Catherine McLeod-Seltzer will continue their executive roles of CEO and President respectively in the amalgamated company. Bill Myckatyn will serve as non-executive Chairman of the amalgamated Board of Directors. Other directors will include Pacific Rim nominees Tony Petrina, Thomas Shrake and Catherine McLeod-Seltzer and Dayton nominees Robert Buchan and David Fagin. Both Pacific Rim and Dayton recognize that the primary driver for shareholder value in the gold industry today is profit, which is best served by the discovery and development of sizeable, economically viable gold deposits with potential for operating costs in the lower quartile on a worldwide basis. Dayton's El Dorado gold project in El Salvador has the potential to become a low-cost underground gold operation capable of generating significant free cash flow in today's gold price environment. The amalgamation of Pacific Rim and Dayton will provide the financial resources to facilitate the immediate advancement of the El Dorado project. El Dorado is an epithermal gold project comprising 35 individual quartz veins that exceed 18 km in aggregate strike length. The El Dorado Mine (which exploited the Minita vein system) historically produced 78,000 ounces of gold at an average grade of 9.6 g/t. In its 2000 Annual Report, Dayton reported an indicated resource below the historic workings of the Minita vein system of 799,200 tonnes averaging 13.7 g/t gold and 97.9 g/t silver, and an inferred resource of 110,600 tonnes averaging 10.8 g/t gold and 76.9 g/t silver. The indicated resource contains 352,700 ounces of gold and 2,516,000 ounces of silver, while the inferred resource contains an additional 38,400 ounces of gold and 273,000 ounces of silver (see note below regarding NI 43-101). Importantly, the most recent drilling by Dayton demonstrates that the better grades in the Minita vein system occur at depth, with the most productive interval between approximately 250 m and 100 m above sea level. Higher grade mineralization has also been drilled at similar depths on the Coyotera Vein, roughly 4 km to the north of the old mine. The vast majority of previous drilling tested selected veins above this 'productive' elevation range. The focus of the merged company will be the discovery and delineation of additional high-grade ounces by drill testing vein targets throughout the El Dorado epithermal system at the 'productive' elevation range. The cash from Pacific Rim's sale of the Diablillos project (see Pacific Rim news releases #01-04, #01-05 and #01-06) will provide the funds to conduct this exploration work in an aggressive manner. In addition to El Dorado, Dayton has a 49% non-operating interest in the Rawhide Mine in Nevada and 100% ownership of the Andacollo Mine in central Chile. Rawhide will cease open pit mining in July, 2002 but will crush lower grade stockpile material for six months and then continue to leach for several years. Rawhide is expected to generate in excess of US $8 million in cash flow to the merged company over the next three years at today's gold prices. Dayton de-consolidated its interest in Andacollo at the end of November, 2000. Andacollo has been actively leaching residual precious metals from the heap since August, 2000 and has also successfully liquidated most of its mining equipment. "We are extremely excited by the win-win opportunity this amalgamation presents," states Pacific Rim CEO Tom Shrake. "The El Dorado gold project represents a unique opportunity to explore a high-grade, potentially low-cost gold deposit with a known resource and substantial upside potential." "The upside potential of the El Dorado project is the primary reason behind Pacific Rim's pursuance of this merger," adds Pacific Rim President Catherine McLeod-Seltzer, "but the amalgamation is further strengthened by Dayton's asset base." Dayton's President and CEO, Bill Myckatyn states, "Rawhide will generate good cash flow at current gold and silver prices over the next few years. The proven technical team and immediate cash that Pacific Rim brings to the merged company will allow meaningful work to be undertaken at El Dorado right away. The merged company will be a very well-financed exploration and development company with a potentially world class asset." Both Pacific Rim and Dayton anticipate holding shareholders' meetings in early April, 2002 to consider the merger. Further information regarding the merger will be included in subsequent shareholder material. Additional information is available on Pacific Rim's website (www.pacrim-mining.com) or by contacting Pacific Rim's or Dayton's offices. Pacific Rim and Dayton will present an audio webcast discussion regarding this announcement on January 9, 2002 at 10:30 am Pacific Time.
