Goldstone Resources Exploration Update

TORONTO, ONTARIO--(Marketwire - May 13, 2010) - Goldstone Resources Inc. ("Goldstone" or "the Company") (TSX: GRC) (PINK SHEETS:GRSZF) is pleased to provide an update on our exploration efforts in the Beardmore-Geraldton area of northern Ontario. Following the merger of Ontex Resources and Roxmark Mines in late 2009 to form Goldstone, a large geological and historical production database has been examined to prioritize exploration targets.

KEY LAKE, GERALDTON

The Key Lake property will be the focus of approximately 15,000m of diamond drilling, scheduled to start on June 1st. Historical drilling by Cyprus Amax and Placer Dome in the 80's and 90's has outlined a 2.5 km long band of gold mineralization that appears to have low grade open pit potential. Goldstone plans to twin some of these historical holes and systematically drill along the 2.5km strike length to explore this potential. This property is located approximately 14km west of the Hardrock Project, where Premier Gold (in joint venture with Goldstone) has announced impressive open pit and underground results.

LEITCH-SAND RIVER MINE, BEARDMORE

In the Beardmore area, compilation and prioritization of targets is ongoing. Several promising areas with limited exploration on strike from the high grade Leitch-Sand River mines will be the focus of diamond drilling later in the fall. Additional programs of ground geophysics, trenching and mapping will be conducted on targets in the area that exhibit structural and geological similarities to the historical high grade deposits.
