Probe Mines Commences 43-101 Resource Estimate on Black Creek Chromite Zone, McFauld's Lake, Northern Ontario

TORONTO, ONTARIO--(Marketwire - May 18, 2010) - The Directors of Probe 
Mines Limited (TSX VENTURE:PRB) ("Probe") are pleased to announce that 
Micon International Limited ("Micon") have been contracted to prepare a 
43-101-compliant resource estimate on its Black Creek Chromite Deposit 
located in the McFauld's Lake area of Northern Ontario. The Black Creek 
Zone was discovered in 2009 on the Probe-Noront Resources ("Noront") joint 
venture property and represents a key segment of the chromite mineralized 
horizon situated between Cliffs Natural Resources ("Cliffs") Black Thor 
deposit and the Cliffs-Spider Resources-KWG Resources Big Daddy deposit. 
The Black Creek zone is currently drilled on 50 metre spacing along a 200 
metre strike length and to a vertical depth of approximately 200 metres, 
and remains open in all directions. A site visit to the property has been 
scheduled for June 8, 2010 and it is expected that the report will be 
completed within six to eight weeks of this date.

Micon has been providing consulting services to the mining industry since 
1988 and during the last two years has undertaken significant work on the 
chromite deposits in the Ring of Fire, producing 43-101-compliant resource 
estimates for the Blackbird and Big Daddy chromite deposits immediately 
southwest of Black Creek.

Dr. David Palmer, President of Probe Mines, states "Our McFauld's Lake 
projects will be a priority for Probe this year and we are fortunate to 
have Micon working with us on the resource estimate for Black Creek. They 
have considerable experience in both resource estimation and the Ring of 
Fire chromite deposits and we look forward to their insight and 
recommendations on Black Creek."
