8:03AM Pan Am silver proven and probable reserves up 20%, 35.4 million ounces added (PAAS) 28.56 : Pan American Silver (PAAS) announces the results of its 2006 yr-end reserve and resource evaluation. In addition to replacing 100% of reserves mined during 2006, co added a further 20%, or 35.4 mln ounces of silver, to its proven and probable reserves. At the co's operating and development properties, measured and indicated resources increased 12.1 mln ounces, while inferred resources grew by 9.9 million ounces. Reserves particularly increased at the co's Morococha and La Colorada mines. At Morococha, proven and probable reserves have increased five-fold since Pan American acquired the operation in mid-2004. At La Colorada, primarily due to the discovery of the new Amolillo zone, 3.6 mln ounces were added to proven and probable reserves in addition to replacing ounces mined in 2006.
