VANCOUVER, BRITISH COLUMBIA--(Marketwire - Aug. 20, 2012) -Blue River Resources Ltd. ("Blue River" or the "Company") (TSX VENTURE:BXR) announces it has received Approval for it's Mines Act Permit Amendment from the BC Ministry of Energy and Mines for its 100%-owned Castle Copper Project, located 12 km northeast of Princeton BC. The exploration permit is for 20 diamond drill holes from 20 drill set-ups and 10 trenches.

The Castle Project totals over 18,000 acres in size, covering an estimated 8 km strike length of the north/south trending Nicola Fault. The Nicola Fault has been interpreted to regionally control copper mineralization found at the Copper Mountain Mine and in the Princeton area.

The Company's initial 2011 diamond drilling program defined copper porphyry-style mineralization over, and beyond the extent of a 500-metre-by-150-metre zone of surface copper mineralization and copper-in-soil geochemical anomalies previously identified by the Company. The 2011 drilling program was designed to test lithology, and alteration beneath the known surface mineralization and it identified strong epidote-chlorite and quartz-sericite alteration, which is consistent with a copper porphyry mineralized system, similar to Copper Mountain Mining's operating Copper Mountain mine, located 25 kilometers south of the Castle Property.

President Griffin Jones states "The initial drill program on the Castle Copper Project encountered copper mineralization in 8 of the 10 holes drilled last year. Of particular interest is the last hole drilled, BXR-11-9, which intersected 200 metres (600 feet) of copper porphyry-style alteration and mineralization, indicating the potential for a large porphyry system. This area, called the Christian Zone, will be the focus of the upcoming diamond drill program."

Earlier this year, Blue River uncovered historic drilling information from a 1972 drilling program on the Property from a B.C. Government Property File research program. This information indicates that copper mineralization may extend to the North and West of the 2011 drilling campaign on the Castle Copper Project, specifically near the Christian Zone area.

Drilling equipment and personnel are being mobilized.
