Probe Mines Announces Commencement of Ground Geophysical Surveys at Its Borden Lake Gold Project Near Chapleau, Ontario

TORONTO, ONTARIO -- (Marketwire) -- 07/06/11 -- Probe Mines Limited (TSX VENTURE: PRB) ('Probe' or the 'Company') is pleased to announce that ground geophysical surveys have commenced on the Company's Borden Lake Gold Project near Chapleau, Ontario. Approximately 100 line kilometers of cut grid, covering over 850 hectares of property, have been established on the Company's land holdings to the north, and along strike, of the Borden Lake Gold Discovery. The new grid is less than three kilometers from the gold discovery and represents the first geophysical coverage over this area. As with the Borden Lake Zone, no drill programs have ever been undertaken on these claims. The entire grid will be surveyed using Induced Polarization ('IP'), magnetic and VLF techniques in order to identify further targets in preparation for drill testing. A previous IP survey indicates that the Borden Lake mineralization, currently being drilled to the south, is ideally suited for this method of geophysics and other zones, if present, should be readily apparent in the data.

The survey is targeting approximately five kilometers of potential strike length along the metasedimentary horizon representing the potential northwestern strike extension of the rocks hosting the Borden Lake gold zone. The target metasediments in this area describe a regional-scale fold distinguished by a coincident magnetic and electromagnetic ('EM') airborne anomaly, similar to the signature of the Borden Lake gold discovery, in the fold nose. Typically fold noses are viewed as ideal sites for mineralizing events owing to their extensional-style deformation and the potential for thickening of mineralization at the fold hinge. The 'Nose' EM anomaly represents a priority target for the project and will be the initial focus of the ground geophysical work. At least five other priority airborne anomalies on the north and south limbs of the fold, along strike of the Borden Lake gold zone, will also be covered by the survey.

Although it is uncommon for gold mineralization to be defined by airborne EM surveys, the Borden Lake Zone locally contains stringer sulphide zones which may be responsible for the airborne signature. The IP survey will also be used to delineate potential sulphide-mineralized zones which may not have been picked up by the airborne survey.

It is expected that drilling of potential targets will commence in the next two to three weeks, as the survey progresses and targets are identified.

David Palmer, President of Probe, states, 'We are excited to start ground work on the northern portion of the property, which, like the Borden Lake gold discovery to the south, has seen no previous exploration and represents an area of significant potential. The presence of airborne targets similar to the Borden Lake zone and within the same interpreted stratigraphic horizon suggests a strong possibility that the northern claims could host multiple gold zones of substantial size. The Borden Lake Zone itself has now been traced over 1,700 metres of strike length and to 340 metres depth.'

The IP survey has been contracted to R.J. Meikle & Associates, who have a long history in the industry of providing geophysical services. Ground magnetic and VLF surveys will be run in conjunction with the IP by Yvan Veronneau, who specializes in the acquisition and interpretation of this data.
