Probe Mines Announces Additional Assay Results for its Borden Lake Gold Project: Infill Drilling Demonstrates Excellent Continuity of Zone, Including 138.3 metres Averaging 1.0 g/t Au

TORONTO, ONTARIO--(Marketwire - Nov. 1, 2011) - PROBE MINES LIMITED (TSX VENTURE:PRB) ("Probe" or the "Company") is pleased to announce that it has received further assays from the ongoing drilling program at the Company's Borden Lake Gold Project near Chapleau, Ontario. Results for diamond drill holes BL11-85 to BL11-95 were received with all successfully intersecting the Borden Lake Gold Zone and returning significant intervals of gold ("Au") mineralization, including intersections of up to 138.3 metres averaging 1 g/t Au with high-grade zones containing up to 3.3 g/t Au over 16.4 metres. Other high-grade occurrences were identified including a 1.5 metre intersection of 15.8 g/t Au.

Drill holes BL11-85 to BL11-95 represent infill holes between previously announced sections and confirm the continuity of gold mineralization along strike and to depths of approximately 300 metres. All holes have successfully intersected the Borden Lake gold zone and the infill program has been effective in delineating a significant portion of the deposit at 50-metre spacing. The aim of the infill program is to upgrade the previously announced gold Resource; expand the Resource to depth; and further delineate the "satellite zones" identified in the Resource Estimate for inclusion in a future resource update.

The gold zone has now been identified along approximately 1,700 metres of strike length from surface to vertical depths of up to 340 metres and contains intersections up to 200 metres wide. The recently reported NI 43-101 Initial Resource Estimate for the Borden Lake gold zone estimated, at a cut-off grade of 0.3 g/t Au, an Indicated Resource of 11,607,000 tonnes averaging 0.8 g/t gold for 305,000 ounces of gold and an additional Inferred Resource of 169,322,000 tonnes averaging 0.69 g/t gold for 3,755,000 ounces of gold. The Resource Estimate was calculated using holes BL11-01 to BL11-77. The drill program is currently on Hole BL11-121 and the gold zone remains open in all directions.

Highlights from the drilling are presented in the following table. Reported drill widths in the tables approximate true widths in these sections. Within the gold mineralized intervals reported here, silver returns average values of up to 1.6 g/t, with individual samples assaying up to 12.1 g/t Ag.

Drill hole BL11-85 was collared on Section 250m SE as a 50-metre infill to sections 200 and 300 metre SE. The hole encountered a 116 metre-wide zone of mineralization averaging 0.8 g/t Au, including two intervals of 18.6 and 14.7 metres averaging 1.2 and 2.3 g/t Au, respectively. Gold mineralization was identified from 74 to 184 metres vertical depth.

Hole BL11-86 was collared on 50-metre infill section 750m SW and was designed to test the mineralized zone to 200 metres vertical depth and identified gold mineralization down to 230 metres vertical depth.

Holes BL11-87 and -88 were drilled on Section 150m SE to infill previous sections at 50 metre-spacing. The holes identified thick sections of gold mineralization gold mineralization from 41 and 174 metres vertical depth and included a 138 metre intersection averaging 1 g/t Au, including 16 metres of 3.3 g/t Au.

Holes BL11-89 and -91 were drilled on infill section 650m NW and intersected up to 88 metre-wide zones of mineralization down to 197 metres vertical depth.

Holes BL11-90, -93 and -95 were collared on Section 100m NW as part of the deep infill drilling, and were designed to test the mineralized zones at 250, 300 and 350 metre vertical depth levels, respectively. The holes all successfully intersected the gold zone, however, the deepest hole, BL11-95, was stopped just after entering the zone at 285 metres vertical depth and will have to be extended in future drilling to confirm the full width of gold mineralization.

Holes BL11-92 and -94 were drilled on Section 550m NW to infill previous sections and test at the 150- and 250-metre depth levels. Hole BL11-92 identified a thick zone of gold mineralization from 34 to 104 metres vertical depth. A narrower zone of mineralization was intersected in Hole BL11-94 due to diabase dyke which cut the zone at 61 metres vertical depth.
