New Ni/Cu/PGM Targets Identified In Michigan

September 5, 2012

Following recent drilling and land acquisition activities by Rio Tinto on parcels adjoining Bitterroot Resources Ltd's (BTT; TSX-V) mineral rights in Michigan, a Bitterroot-commissioned aeromagnetic survey has been completed. Analysis of data from the aeromagnetic survey has identified a number of new targets located on Bitterroot's 100%-owned mineral rights. Several of Rio Tinto's drill collars are located within 180 metres of Bitterroot's mineral rights, testing the area shown as "Target 2" on the attached map.

The new targets have potential to host conduit dyke systems which are favourable for the accumulation of high-value Ni/Cu/PGM-bearing sulphides similar to Rio Tinto's high-grade Eagle deposit (3.2 million tonnes @ 3.89% Ni and 3.04% Cu). The Eagle deposit is located in a similar geological setting, approximately 75 km northeast of the area covered by Bitterroot's aeromagnetic survey. The Eagle mine is under construction and is expected to be in full production in 2014.

The attached map shows magnetic signatures and land ownership on four of Bitterroot's Ni/Cu/PGM targets, which are similar to the magnetic signature of the Eagle deposit. Other targets manifest themselves as more tabular features which may represent the remnant keels of larger intrusive bodies.

Bitterroot controls a growing portfolio of nickel/copper/PGM exploration targets within its 360 square miles of wholly-owned mineral rights in the Upper Peninsula of Michigan.

Management is currently assessing various financing and industry-related options for the exploration of these targets.
