(TSX Venture Exchange Symbol: ORS) (OTC Pink: ORESF) (FSE: O2R2) (the “Company”) is pleased to announce the initial assay results received from the Phase I exploration program on the Francisca Gold Project in Salta Province, Argentina.

At the South Gold zone, mapping indicates a stockwork width from 40-70 metres averaging 50 metres along a 400-500 metre strike length. The zone consists of highly sericite argillic altered porphyry and hornfels host rocks cut by a dense stockwork of thin light brown limonite veinlets with thin dark quartz vein centres and thicker dark limonite quartz veins that are both vertical and shallow dipping.
