PAN AMERICAN SILVER CORP. Date: June 16, 2003 By: /s/ Ross Beaty -------------------------- Ross Beaty Chairman and C.E.O. -2- (PAN-AMERICAN SILVER CORP. LETTERHEAD) NEWS RELEASE June 16, 2003 PAN AMERICAN SILVER ADVANCES ALAMO DORADO AND MANANTIAL ESPEJO DEVELOPMENT PROJECTS (all figures in US dollars unless otherwise stated) Vancouver, Canada - Pan American Silver Corp (NASDAQ -- PAAS; TSX -- PAA) is pleased to announce excellent progress at two of its major development projects, Alamo Dorado and Manantial Espejo, as part of its aggressive growth strategy. The Alamo Dorado project in Mexico, acquired in early 2003 with the purchase of Corner Bay Silver, continues on pace to feasibility by the fourth quarter. Currently, Alamo Dorado contains proven and probable reserves of 35.5 million tonnes grading 68 g/tonne silver, or 77 million ounces of silver as reported at December 31, 2002 (John Thornton, Mintec, Qualified Person). A recently completed seven-hole drill program* returned excellent silver and gold grades and provided samples for metallurgical testwork to update the June 2002 feasibility study completed by Corner Bay. AMEC E&C Services Inc. has been retained to confirm the economic benefit of adding a conventional mill circuit to a small-scale heap leach operation. A conventional mill may improve recoveries, thereby reducing production costs. All permits for the heap leach operation have been received, except for water permits; however, the agreements to lease water and the corresponding permits are expected to be in place by October. Power supply options have been examined and discussions to source power are underway with the Mexican power authority. A production decision, complete with financing plans, is expected by the end of this year. Pan American expects Alamo Dorado to produce 6 million ounces of silver annually at an average cash cost of $3.25 per equivalent ounce of silver starting in 2005. In Argentina, a 6,000 m infill drilling program has been completed on the 50% owned Manantial Espejo silver-gold joint venture. The results have confirmed the size of the deposit and increased the Company's confidence in its geological model, leading the joint venture to accelerate the commissioning of a feasibility study on the property. The study will be initiated in the fourth quarter for completion in the fall of 2004. Over the remainder of the year, geotechnical and environmental work will proceed to facilitate permitting. Currently, reported measured and indicated mineral resources at Manantial Espejo total 4.39 million tonnes grading 264 g/tonne silver and 4.51 g/tonne gold, or 37 million ounces of silver and 620,000 ounces of gold, with an additional 13 million ounces of silver and 185,000 ounces of gold identified in inferred resources of 1.59 million tonnes grading 259 g/tonne silver and 3.65 g/tonne gold (Stewart Wallis, P.Geo, Qualified Person). The feasibility study will evaluate the potential for Manantial Espejo to produce 4 million ounces of silver and 70,000 ounces of gold annually. .../2 1500-625 HOWE STREET, VANCOUVER, BC CANADA V6C 2T6. TEL 604.684.1175 FAX 604.684.0147 www.panamericansilver.com In 2003, Pan American expects to produce more than 10 million ounces of silver. The completion of the La Colorada expansion currently underway in Mexico, coupled with the successful development of Alamo Dorado and Manantial Espejo will see Pan American's production double to 20 million ounces of silver annually in 2005.
