(Full text of press release from Canadian Corporate News) JUNE 20, 1997 Yamana Resources Finds Bonanza Silver In Santa Cruz, Vanguardia, Argentina SPOKANE, WASHINGTON--Yamana Resources Inc. announces that ongoing reconnaissance exploration in the western region of the Vanguardia epithermal gold district has lead to four new discoveries of precious metal systems, some containing bonanza-grade silver. Rock-chip sample results assayed as high as 109 oz/t Ag (3,400 g/t). As a result of these finds, Yamana has claimed four new properties which lie west and northwest of the Cerro Vanguardia gold mine development, with an announced resource of 3.8 million ounces of gold and 45 million ounces of silver (see attached map). The expanded property portfolio brings Yamana's holdings in the district to 17 cateos (exclusive prospecting rights) covering 1,054 square kilometers. "Lejano," the northern-most cateo, covers the best of the sample results, where 27 rock-chip samples have been collected, each over a minimum area of 15 square meters. Of these, 55 percent grade in excess of 30 g/t Ag, with 33 percent greater than 100 g/t Ag, and 15 percent greater than 1,000 g/t Ag. The best sample assayed 3,400 g/t Ag. Gold and silver mineralization occurs in strongly hydrothermally altered, Jurassic-age rhyolitic volcanic rocks exposed in two prominent hills, each more than 1 kilometer long and 300 meters wide. It is often associated with sheeted to stockwork quartz veining. About 80 percent of this 60-square-kilometer cateo remains to be examined. The southern-most cateo, "Bacon," located approximately 200 kilometers south of Lejano, encompasses 44 square kilometers adjacent to the Manantiel Espejo gold-silver vein deposit in which Triton Mining Corporation holds a purchase option from Barrick Gold Corporation. Triton has announced a global resource of 1.1 million ounces of gold equivalent (Au + Ag). One structural zone on Bacon consists of many small, sheeted quartz veins cutting silicified rhyolitic tuff beds. This zone continues along strike more than 3 kilometers over a variable width of up to 30 meters, and lies on the same regional structural corridor hosting the Manantiel Espejo deposit. Preliminary sampling has yielded assays up to 0.5 g/t Au and 730 g/t Ag. Two more cateos,"Bola" and "Vista," are situated between Lejano and Bacon and together make up an additional 141 square kilometers covering a similar Jurassic-age volcanic setting. Large crater-like structures (calderas) are seen on LandSat images. Both properties exhibit big zones of sheeted and stockwork quartz-vein complexes several kilometers in strike length. Both also transgress calderas and contain anomalous gold and silver concentrations. With less than 10 percent exploration coverage, limited sampling revealed in excess of 0.2 g/t Au in both areas, accompanied by up 12 g/t Ag. Geological mapping and further systematic geochemical sampling of these encouraging, silver-rich prospects will be undertaken in the third quarter of this year, following the winter shutdown, with the objective of defining more drill targets for testing in the following quarters. The Santa Cruz, Vanguardia program is operated during the exploration stage by Yamana and funded by Rio Algom Limited, who may earn a 50-percent interest by spending US$20 million on exploration by August 31, 2001. Yamana Resources is a Canadian exploration company holding interests in 12 projects encompassing more than 90 properties covering over 36,000 square kilometers (8.9 million acres) in Argentina, Chile, Paraguay, Papua New Guinea, Indonesia and Washington state.
