Probe Mines Announces Additional Assay Results for Its Borden Lake Gold Project and Continued Expansion of Gold Mineralized Zones Including Up to 17 Metres of 3.0 g/t Au

Highlights:

• Results also include 87.6 metres @ 1.1 g/t Au and 37.4 metres @ 1.5 g/t Au
• Main zone mineralization still open in all directions; expanded to depths greater than 500 metres
• Above average gold-bearing intervals continue to be identified in the Hanging Wall zone
• Infill drilling confirms continuity of main zone mineralization

PROBE MINES LIMITED (TSX VENTURE:PRB) ("Probe" or the "Company") is pleased to announce that it has received further assays from its ongoing drilling program at the Company's Borden Lake Gold Project near Chapleau, Ontario. Results for diamond drill holes BL12-227 to BL12-246 were received and continue to expand the Borden Lake gold zone to depth, identify new mineralization to the hanging wall side (northeast) of the main zone of mineralization and confirm the main zone continuity through infill drilling. Of the twenty new holes, four represent expansion of the main zone mineralization to depth; nine represent drilling in the immediate hanging wall of the main zone testing for parallel gold zones; five were drilled as a fence in the far hanging wall side of the main gold zone to test stratigraphy in this area; and the remaining two were drilled as infill to previous drilling of the main zone.

As with previous depth expansion drilling on the main mineralized zone, results suggest that gold grades are improving, with all significant intersections reported here returning values over the 0.6 g/t gold ("Au") cut-off used to define the Updated Resource (see news release dated April 2, 2012). Results also show that many of the intersections are well above 1 g/t Au, including Hole BL12-239 which returned a 37.4 metre interval grading 1.5 g/t Au within an 87.6 metre intercept averaging 1.1 g/t Au and Hole BL12-233 which contained a 17 metre intercept grading 3 g/t Au within a 37.1 metre interval averaging 1.9 g/t Au (Section 1100m SE). Drilling has now expanded gold mineralization to below the 500-metre vertical depth (Section 300m NW), and will continue on all sections to extend the zone.

The Hanging Wall drilling program is continuing to identify and delineate parallel gold zones to the northeast of the main mineralized horizon. The majority of the holes reported here have intersected gold-bearing intervals above the main zone, which are typically narrower than the main zone, but can also contain above average grades. Highlights include a 5.6 metre intercept averaging 1.0 g/t Au in Hole BL12-234 (Section 500m NW) and a 22.9 metre interval grading 0.6 g/t Au in BL12-246 (Section 700m SE), which also includes a 5.6 metre intersection averaging 1.0 g/t Au. Continued drilling on this program will be required to further delineate gold mineralization that could potentially be added to future Resource updates. The hanging wall zones could be important to further evaluation of the deposit as they can potentially add new gold resources in an area that already falls within the postulated pit outline generated by the most recent Resource Estimate.

Part of the summer drilling program also included a new fence of five holes drilled 400 metres to the northeast of previous drilling on the Main and Hanging Wall, which tested a 400 metre section of stratigraphy in a previously untested area. Of the five holes, one returned a significant, higher-grade intercept represented by a 1-metre interval in Hole BL12-235 averaging 3.0 g/t gold. The presence of gold in the area is encouraging and will require further follow-up.

Only two infill holes are reported in these results and were drilled on Sections 400m NW and 500m NW, both of which confirmed the continuity of mineralization. The highlight of the infill drilling was hole BL12-240, returning an interval of 33.4 metres averaging 1.0 g/t Au, which was at a higher-grade than the intercepts immediately surrounding it.

The following tables show selected results from Depth Extension, Hanging Wall, Fence and Infill drilling programs. For the majority of holes, drill width approximates true width. For holes BL12-230, -231 and -239 true width is approximately 85-90% of drilled width.

Dr. David Palmer, President and CEO of Probe, states "The Borden Lake project continues to produce impressive results and increases our confidence in this expanding gold zone. After 246 drill holes we are still open in all directions on the deposit and continue to find new gold mineralization in the surrounding area. We strongly believe that Borden still has a lot to offer and will continue our aggressive pace to advance the project through the Fall. Our summer exploration programs have helped us considerably in understanding the area and we will apply this knowledge to upcoming drilling programs on the deposit and our regional exploration. We currently have four drills turning on the deposit, with one expected to move back to testing exploration targets in other areas of the property, and will keep investors well-informed as results from the drilling become available."

Probe has instituted a strict quality assurance and quality control ("QA-QC") program for the Borden Lake drill core sampling, with each fire assay furnace batch of 40 samples including two certified reference materials (standards), one blank sample and one core duplicate sample. Quality control guidelines and ongoing QAQC monitoring are being carried out by Probe personnel.
