Probe Mines Limited Provides Update on its Borden Lake Project Drilling Program

Highlights:

- Potential mineralized zone extended to 550 metres
- Zone still open in both directions along strike and at depth
- Assay results expected by mid-January

TORONTO, Dec. 21, 2010 - The Directors of Probe Mines Limited (TSX VENTURE: PRB) (Probe) are pleased to announce that the Company has completed seven holes, totaling 1,684 metres, of a 5,000 metre drilling program on its Borden Lake project near Chapleau, Ontario. Drilling operations have been suspended over the holiday season and will resume on January 12th, 2011.

The seven holes drilled to date represent four individual setups spaced 100 metres apart and are designed to test the width of the zone at two depths. Visual results suggest that all seven holes have intersected the Borden Lake gold zone for an additional 300 metre strike extension from the discovery hole. The zone is still open in both directions along strike and at depth, and when combined with the Phase I program represents a potential 550 metre-long section of mineralization. These thick mineralized sections of the host Timiskaming sediments range between 180 metres and 200 metres in width (true width) and contain similar sulphide concentrations and assemblages as observed in the Phase I drilling program.

The Phase I program comprised eight holes testing a surface gold showing on the property. Thick zones of continuous gold mineralization were intersected in holes BL10-02 to BL10-07 representing 250 metres of potential strike length along the gold zone. Hole BL10-02 intersected 91 metres averaging 2 g/t Au while Hole BL10-04 returned a 78 metre interval averaging 0.7 g/t Au and Hole BL10-05 returned an 86 metre intercept grading 1 g/t Au. Within all of these broad mineralized intercepts at least two significant higher-grade zones were identified with intervals returning up to 5.3 g/t Au over 5 metres including samples of up to 15.5 g/t Au over one metre. All holes in the Phase I program ended while still in mineralization and the full width of the zone had not been known until the start of the Phase II drilling.

Over 1,500 samples have been submitted to Accurassay Laboratories in Thunder Bay from the Phase II drilling and results are expected by mid-January. Probe has instituted a strict quality control and quality assurance (“QA-QC“) program for the Borden Lake sampling, consisting of the insertion of sample standards, blanks and sample duplicates in predetermined batches. Quality control guidelines have been set out by Independent Qualified Person (“IQP“) Ms. Tracy Armstrong, P.Geo., of P & E Mining Consultants Inc.

Results of the program will be released as soon as they have been received and reviewed.
