Probe Mines Announces Commencement of Drilling on the Lake Shore Gold Joint Venture Property, West Timmins, Ontario; Borden Lake Update; Grant of Options

TORONTO, ONTARIO -- (Marketwire) -- 05/26/11 -- Probe Mines Limited (TSX VENTURE: PRB) ('Probe' or the 'Company') is pleased to announce that drilling has commenced on its West Timmins property currently under Joint Venture with Lake Shore Gold (TSX: LSG) ('Lake Shore'). The diamond drill program will test a prospective target approximately 800 metres east from both the Timmins Mine and the Rusk-Porphyry Zone discoveries on Lake Shore Gold's wholly owned Thunder Creek property. The target is distinguished by a coincident magnetic-induced polarization anomaly in the vicinity of a single drill hole completed by Probe in 2004, from which Probe reported alteration in the metasediments similar to that found near the mineralized zones on Thunder Creek. These results suggest the potential presence of a buried syenite porphyry similar to those hosting gold mineralization nearby. The program will consist of one 500 metre-long drill hole designed to test the target at approximately 300 metres depth. The Company will provide updates on the results of the drilling as soon as they are available.

The West Timmins project is a Joint Venture between Lake Shore (55%) and Probe (45%), with Lake Shore acting as operator. Target selection for the current program was made by Probe Mines, while the drilling will be carried out under the supervision of Lake Shore's geologists. The property is comprised of 52 claim units surrounding Lake Shore's Timmins Mine property to the north, east and southeast. The Timmins Mine deposit has probable reserves of 812,000 ounces and achieved commercial production on January 1, 2011. The Porphyry Zone discovery at Thunder Creek is located approximately 800m west of the joint venture property and contains drill intersections of up to 83.4 metres averaging 12.75g/t Au in TC09-68b (see Lake Shore Gold's press release dated June 24, 2009) and 99.6 metres grading 4.91 g/t Au in TC650-001 (see Lake Shore Gold's press release dated November 24, 2010).
