VANCOUVER, BRITISH COLUMBIA--(Marketwired - June 26, 2013) - Tarsis Resources Ltd. (News - Market indicators) ("Tarsis" and "the Company") is pleased to announce that option partner Osisko Mining Corporation (TSX:OSK) ("Osisko") has advised that its exploration team commenced work in May 2013 at the Erika property. 

The Erika property is located in the Guerrero Gold Belt and covers approximately 16,000 hectares, located in Guerrero State, Mexico. The property is accessed by paved road via Federal Highway 95, which crosses the eastern boundary of the claims. Acapulco is 150 km south and Iguala is 47 km north of Erika.

The exploration being carried out will consist of detailed geological mapping and supplemental geochemical sampling. This work is designed to identify drill targets that will likely be tested during Q4, 2013.

Under the terms of the option agreement, Osisko must spend $500,000 on exploration at Erika before February 2014 as part of its earn-in commitment.

To earn an initial 51% interest in the Erika project, Osisko must make staged cash payments to Tarsis of $1,000,000 ($50,000 paid to date) and spend $4,000,000 on exploration over four years. Subsequent to their initial earn-in, Osisko may increase their ownership to 75% by completing a feasibility study on the project.
