The extensive Claudia Gold Silver Project which lies directly south of the Cerro Vanguardia (CVSA) gold-silver mine has five epithermal prospects with multiple targets. The Claudia project was staked in 2004 as part of Mirasol’s Santa Cruz project generation strategy. Following up reconnaissance targets identified additional mineralization centres that led to more staking and the establishment of a sizeable land position. In 2012 Mirasol discovered the large 15 km long Curahue vein trend which hosts six large individual vein trends.

During October 2017 through March 2019, Mirasol partnered with OceanaGold who invested C$2 million and drilled 2,500 m in 12 holes at Claudia. From February 2016 to January 2017, Mirasol was in a joint venture with CVSA which completed 7,525 m of reverse-circulation (RC) and diamond core (DDH) drilling at the project. The drilling was mostly focused on the “Io” vein, a 2.2 km long vein zone in the Curahue prospect where CVSA defined a body of gold and silver mineralization.

During the 2008 through 2010 joint venture with Hochschild, more than 4,000 line kilometres of ground magnetometry, and 249 line kilometres of gradient array IP geophysics covering six blocks was conducted, along with 1,155 rock chip samples and MMI geochemistry. A total of 3,794 metres of core drilling in 26 holes were completed in December 2007, and 3,168 metres of reverse circulation (RC) drilling in 25 holes was completed in December 2008.
