Atacama Minerals Holds Ground-Breaking Ceremony for New Agitated Leach Plant

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - April 19, 2007) - Atacama Minerals Corp. ("Atacama" or the "Company") (TSX VENTURE:AAM) is pleased to announce a ground-breaking ceremony was held for the Company's new agitated leach plant on April 17, 2007, at the Aguas Blancas Mine in northern Chile. The ceremony was held under the direction of Company President, Edward F. Posey and the Region II Representative of Chilean President M. Bachelet, Intendenta Marcela Hernando. Several local dignitaries and mining authorities were also in attendance.

The decision by Atacama Minerals to build a full-scale mechanical agitated leach plant was made after a year of successful pilot plant testing. The conversion from the current heap leaching method to full agitated leach is expected to increase overall iodine recovery from the current level of 60% to a level in excess of 85% with an accompanying overall decrease in the use of water. The new plant is expected to be operational by years end giving the Company the capability to increase production from 1,000 to 1,500 tonnes of high quality iodine per year. The total estimated cost of the new plant is $25.5 million, expected to be funded by internal cash flow.

Mr. Posey, President of the Company, stated, "The conversion from heap leaching to agitated leaching is not only more efficient with less use of water, but will increase the overall life of mining operations. We are proud to be the first company in Chile to utilize this particular method for this type of mining operation."

Intendenta Marcel Hernando stated that, "This new project is not only a valuable contribution to building the mining economy of Region II, but is also an important source of employment in support of the economic and social life of the region."

On behalf of the Board

Edward F. Posey, President
