DIAMOND DRILLING PROGRAM UNDERWAY AT CASTLE COPPER PROJECT, PRINCETON, B.C

September 14, 2011

Vancouver, B.C., Dated: September 14, 2011. Blue River Resources Ltd (TSX.V: BXR) announces it has commenced drilling on its Castle Copper Project, located 12 km north of the town of Princeton, BC and 25 km north of Copper Mountain Mining Corp’s operating Copper Mountain open pit copper mine.

The Castle Property 2011 diamond drilling program targets 3,000 meters of NQ sized drilling
from 10 holes and is designed to test the depth extension of a zone of anomalous copper
mineralization previously identified from Company and historical surface exploration work. This 500 m by 150 m zone of anomalous copper mineralization consists primarily of malachite, chalcopyrite, pyrite and magnetite with minor bornite and possibly chalcocite and has been defined by a series of geochemical soil sampling surveys, trenches, and ground based geophysical surveys. Results from all these surveys are being utilized to guide the current drilling campaign. The drilling program is anticipated to last for 8 weeks and all core samples will be shipped to AGAT Laboratories of Burnaby, B.C. for multi-element ICP analyses.

President Griffin Jones states: “After assembling one of the largest mineral claim land packages in the Princeton area, this drill program is the first phase toward determining the true potential of the Castle Project to host a large-tonnage porphyry copper mineral deposit.”

The Castle project totals approximately 6,500 hectares (16,000 acres) and Blue River holds a
100% interest therein. A 43-101 Technical report on the Castle Property is available for viewing
on the Company’s website or on SEDAR.COM.

Paul D. Gray, P.Geo., Company Director and a qualified person for the purpose of National
Instrument 43-101 has reviewed and approved the contents of this news release.
