If positive outcome is received at the Hydraulic Committee meeting and the Comision Nacional del Agua ("CoNAgua" or "CNA"), the Mexican Federal water governing board supports the arrangements, Pan American will proceed to close the merger as soon as possible. - End - Ross Beaty, Chairman or Rosie Moore, VP Corporate Relations, Pan American, 604-684-1175 Peter Mordaunt, Chairman or Steve Brunelle, Vice President, Corner Bay, 416-368-6240 CAUTIONARY NOTE Some of the statements in this news release are forward-looking statements, such as estimates of future production levels, expectations regarding mine production costs, expected trends in mineral prices and statements that describe Pan American/Corner Bay's future plans, objectives or goals.
