Probe Mines Announces Additional Assay Results for Its Borden Lake Gold Project and Exploration Update

TORONTO, ONTARIO--(Marketwire - June 5, 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 BL12-160 to BL12-196 were received and continue to expand the Borden Lake gold zone to depth and confirm its continuity through infill drilling. Highlights from the drilling include intersections of up to 82 metres averaging 1.1 g/t gold ("Au") in Hole BL12-193 (Section 600mSE) to a vertical depth of 392 metres and a 72 metre intersection averaging 1 g/t Au, containing a 21 metre interval grading 1.4 g/t Au, starting from surface on Section 250m NW in Hole BL12-179. The majority of intersections also contain higher-grade intervals, confirming the continuity of the higher-grade core identified in the mineralized zone and highlighted by the recent updated NI 43-101 Resource Estimate (see release dated April 2, 2012) which delineated an Indicated Resource of 1,498,000 ounces of gold averaging 1.46 g/t gold and an additional Inferred Resource of 407,000 ounces of gold averaging 1.30 g/t gold, at a 1.0 g/t cut-off grade, within a larger pit-constrained Resource of 2,735,000 ounces of gold averaging 1.04 g/t gold in the Indicated category and an additional Inferred Resource of 683,000 ounces of gold averaging 0.93 g/t gold, at a 0.6 g/t cut-off grade.

Of the 37 holes announced, 16 represent step-out holes to depth and indicate extensions of the mineralized zone of up to 203 metres deeper (vertical depth) than previously reported for these sections. Nineteen holes were drilled on 50 metre-spaced infill to previous shallow drill holes and confirmed the continuity of mineralization between surface and 138 metres depth. One hole, BL12-194, was drilled to complete deeper infill drilling on section 650m NW, while another, BL12-162, was drilled down-dip on Section 600m NW to assist in waste modeling.

The following tables show selected results from Depth Extension, Shallow Infill, Deep Infill and Waste Modelling drill holes. For the majority of holes, drill width approximates true width. For holes BL12-165, -170, -172, -180, -182, -186, -193 and -195 true width is approximately 80% of drilled width, and Hole BL12-162 was drilled down-dip.

Exploration Update

Exploration programs continue to expand at the Borden Lake Project, with four drills currently turning on the property, a geochemical orientation survey in progress, local and regional geological mapping programs being initiated, advanced metallurgical testing underway and environmental testing continuing. The Company plans to utilize the 2012 field season to build its knowledge base for the Borden Lake-style gold mineralization in order to apply this to regional exploration programs targeting potential similar zones on the rest of the property as well as gaining a better understanding of the deposit itself. Probe currently has over 17 kilometres of previously unexplored strike length within the Borden Lake Belt to investigate.

Drilling on the Borden Lake Zone is continuing, utilising three of the four drill rigs with one testing further depth extensions (>500 metre depth); one testing for, and further delineating, parallel satellite gold zones on the hanging wall side (northeast) of the main mineralized zone; and one continuing to delineate mineralization at the southeastern end of the gold zone.

A fourth drill rig has recently been mobilized back to the "Fold Nose" area and is testing ground and airborne geophysical targets, after completing exploration drilling on the Borden Lake South Option property of Reliant Gold Corp.

The Company has also just completed a soil geochemical orientation survey over the Borden Lake property, which is designed to evaluate the effectiveness of several geochemical techniques in identifying Borden-style gold mineralization. The results of the orientation survey will be used to design regional soil surveys in other areas of the project to help identify and prioritize future drill targets.

Local and regional geological mapping programs have also begun on the project, and will focus on the Borden, Borden North and Borden South areas. The goal of the mapping is to develop a geological model for this relatively unknown area to apply to local and regional exploration.

As part of the continuing evaluation of the Borden Lake deposit, over 500 samples have now been submitted for metallurgical test work. This is compared to only 36 samples that were used in the original Scoping Metallurgical Study (see release dated November 28, 2012) which generated two metallurgical composites. The current testwork will evaluate a much broader spectrum of grades and cover a more extensive area of the deposit.

The Project's Environmental Baseline Study, which commenced in late summer 2011, is also continuing and 2012 programs are currently being planned and implemented by AECOM under the supervision of Dr. Nicola Lower, Senior Fisheries Biologist. The environmental characterization of the site will be used to assist in project planning and to enhance the efficiency of the project permitting process.

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.
