VANCOUVER, Oct. 4, 2012 /CNW/ - Mirasol Resources Ltd.   ("Mirasol") is pleased to announce that it has finalized the definitive exploration option agreement (the "Agreement") for its 100%-owned Espejo Project, located in Santa Cruz Province, southern Argentina, pursuant to a letter of intent announced previously (April 27, 2011). . The Agreement provides for the optionee to earn a 51% interest in the Espejo Project upon completing a US $4 million investment in exploration over four years from the date of the Agreement, with certain cash payments.  After earn-in, the optionee's participating interest may be increased to 61% on completing a NI 43-101 feasibility study, and further increased to 70% by providing mine financing at commercial terms, if requested by Mirasol. The Espejo Project hosts a number of discrete drill targets identified by Mirasol through its proprietary targeting process (see news releases of January 16, 2007 and June 16 and 28, 2008).  Previous exploration conducted by Mirasol included detailed ground magnetic and gradient array IP (induced polarization) geophysical surveys which identified multiple prospective chargeable structures located beneath shallow depths of gravel cover.  The Agreement provides for exploration expenditures on the property of US$300,000 during the first year, with a total of US$200,000 to be spent on areas outside of Mirasol's existing exploration program during the first two years of the Agreement.
