Cornerstone Capital Resources Inc. announced results of a Phase 3 diamond drilling program at the Gama prospect which is located in the northwestern part of the Shyri property in southern Ecuador. The project is strategically located 15 km west of the Quimsacocha high-sulphidation epithermal gold-silver-copper deposit, 15 km south of the Rio Blanco low-sulphidation gold-silver deposit and 10 km southeast of the Chaucha porphyry copper-molybdenum deposit. The Phase 3 drilling commenced in mid-October 2012 and was completed in mid-December.

The program comprised five (5) holes totaling 2,253.3 metres (m) which were drilled to test the Satoshuaycu porphyry copper-gold target. Satoshuaycu forms a large (4 km x 1 km) target defined by a copper-gold-molybdenum soil anomaly coincident with induced polarization (IP) chargeability and magnetic high anomalies. The drill program tested the Satoshuaycu target over an area of approximately 1.5 km (north-south) by 0.75 km (east-west), and to a vertical depth of 450 m. The drill holes confirmed the presence of porphyry-style hydrothermal alteration; however, the system appears to be only weakly mineralized in the area tested.

The mineralization observed in drill core is considered sufficient to explain the multi-element soil anomaly and IP chargeability and magnetic high anomalies. Assay results have been received from the first 3 holes of the program (GAD-12-014 to GAD-12-016). Holes GAD-12-017 and GAD-12-018 were logged and sampled but not assayed to avoid additional cost in light of the lack of any significant visible mineralization in the core.

The most significant intercepts (greater than 20 m at greater than 200 ppm copper and/or greater than 200 ppm zinc, and/or greater than 15 ppm molybdenum) from the drilling program.
