Probe Mines Announces Additional Assay Results for Its Borden Lake Gold Project: Expansion and Infill Drilling on the Main Mineralized Zone Returning Excellent Values
Highlights: - Continued improvement in the higher-grade core with numerous intercepts above 1.5 g/t Au, including 29 metres averaging 1.7 g/t Au and 29.2 metres grading 1.6 g/t Au; - Main zone mineralization still open in all directions - Gold-bearing intervals continue to be identified in the Hanging Wall zone, including high-grade intercepts of up to 9 g/t Au over 4 metres; - Infill drilling continues to improve main zone mineralization with intervals of up to 95.6 metres averaging 1.4 g/t Au
TORONTO, ONTARIO--(Marketwire - Dec. 18, 2012) -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 BL12-272 to BL12-296 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 and confirming the main zone through infill drilling. These results continue to show improvement in the Borden Lake deposit outside the area of the recently announced high-grade mineralization (see News Release dated December 12, 2012), particularly with respect to the higher-grade core. Follow-up drilling is now being planned for the high-grade mineralization identified at the southeast end of the deposit, which will be a focus in 2013.
Of the twenty-five (25) new holes, seven (7) represent expansion of the main zone mineralization to depth; seven (7) represent drilling in the immediate hanging wall of the main zone testing for parallel gold zones; and the remaining eleven (11) were drilled as infill to previous drilling of the main zone.
As with previous expansion and infill drilling on the main mineralized zone, results show a consistent improvement in overall grades with all significant intersections reported here returning values at or above the 0.6 g/t gold ("Au") cut-off used to define the Updated Resource (see news release dated April 2, 2012). The higher-grade core, which has become an integral feature of the mineralized zone, also shows continued improvement with a number of intersections averaging above 1.5 g/t over appreciable widths. Highlights from this drilling include 29 metres grading 1.7 g/t Au and 29.2 metres averaging 1.6 g/t Au in drill holes BL12-272 (Section 100m SE) and BL12-274 (Section 0m), respectively, with a number of high-grade zones including 12 metres of 3.9 g/t Au (BL12-294) and 6 metres of 6.3 g/t Au (BL12-293) on sections 450m SE and 1000m SE, respectively. Hole BL12-294 also returned an impressive intercept averaging 1.4 g/t Au over 95.6 metres.
The Hanging Wall drilling program remains successful in delineating gold mineralization above the main deposit to the northeast. Four of the reported holes contain significant intersections with respect to both width and grade, including a 4 metre interval grading 9.1 g/t Au (BL12-288) and a 35 metre-wide intercept averaging 0.6 g/t Au (BL12-286). The Company will now begin evaluating the results on the Hanging Wall program to direct future drilling on these gold zones.
The following tables show selected results from Depth Extension, Hanging Wall and Infill drilling programs. For the majority of holes, drill width approximates true width. For holes BL12-282 and -293 true width is approximately 90% of drilled width.

Dr. David Palmer, President and CEO of Probe, states, "We are extremely pleased with the results that continue to come out of the project. Not only have we recently shown the potential for much higher grades at Borden, but we are also seeing improvement within the previously reported resource area. Borden displays a potential that isn't seen in many of the more advanced projects and we are looking forward to continuing this success in 2013.
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.
