Probe Mines Announces Formation of Joint Venture With Lake Shore Gold Corp on West Timmins Project; Drilling Program Planned for January 2011

TORONTO, Dec. 13, 2010 - The Directors of Probe Mines Limited (TSX VENTURE: PRB) ("Probe") are pleased to announce that Lake Shore Gold Corp ("Lake Shore Gold") has vested a 55 percent interest in the Company's West Timmins property, located immediately adjacent to Lake Shore Gold's Timmins Mine property, and will act as Operator of the project. Probe will retain a 45 percent interest in the claims. A Joint Venture Management Committee (the "Committee") has been formed with two representatives from each company. The Committee is currently planning a diamond drill program to 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, which intersected alteration in the sediments similar to that found near the mineralized zones on Thunder Creek. The drill program will consist of approximately 500 metres and be completed in the first quarter of 2011.

Dr. David Palmer, President of Probe states "We are pleased to be working with Lake Shore Gold on the West Timmins Project. Their experience in the area will be invaluable as we continue to explore the potential of the property under the new Joint Venture."

The West Timmins property is comprised of 52 claim units surrounding Lake Shore Gold's Timmins Mine property to the north, east and southeast. The Timmins Mine deposit has probable reserves of 812,000 ounces and is currently undergoing underground development prior to production. 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).
