Probe Mines Receives Preliminary Geophysical Results for a New Target at Borden Lake

TORONTO, ONTARIO -- (Marketwire) -- 07/25/11 -- Probe Mines Limited (TSX VENTURE: PRB) ('Probe' or the 'Company') is pleased to announce that it has received geophysical results for an Induced Polarization ('IP') survey currently being conducted just north of its Borden Lake gold discovery near Chapleau, Ontario. The ground geophysical program is targeting approximately seven kilometers of interpreted strike length of the Borden Lake Belt, on-trend with the known gold mineralization. These preliminary results are being obtained in the area of an airborne anomaly referred to as the 'Nose' target, which is situated in a fold hinge, commonly called a 'fold nose', located less than three kilometers, on strike, from the Borden Lake Zone.

The IP results over the Nose Target are encouraging and closely resemble those obtained for the Borden Lake gold zone through a previous IP survey, which showed a distinctive signature over the gold mineralization. Although very similar, the new IP anomaly is also slightly stronger, and possibly thicker, than the one obtained over the Borden Lake Gold Zone. In addition, an unexpected, second, parallel anomaly, showing the same signature, was also identified in the Nose area and has become another priority target. Both new targets are on Probe's 100%-owned claims.

At present there is no supporting evidence indicating that the anomalies are related to gold mineralization, however, they are of sufficient interest to warrant drill testing, which is now scheduled to start in the second or third week of August following a scheduled break from drilling operations.

David Palmer, President of Probe, states, 'While these results are very encouraging, we are still on a learning-curve with respect to our understanding of the mineralizing system. These exploration programs will contribute significantly to that knowledge and help to guide future programs.'

The IP geophysical survey, which is being carried out by R.J. Meikle & Associates, is now approximately 20% complete.
