Mantis Minerals Commences Fieldwork on Probe Mines' Tamarack Property in the McFauld's Lake Area, James Bay Lowlands, Ontario

TORONTO, ONTARIO--(Marketwire - Dec. 10, 2007) - The Directors of PROBE MINES LIMITED (TSX VENTURE:PRB) are pleased to announce that Mantis Mineral Corp ("Mantis") has commenced fieldwork on the Company's Tamarack Property located in the McFauld's Lake area of the James Bay Lowlands, Ontario. The property is currently under option to Mantis, through an option-joint venture agreement announced in October 2006.

Mantis has completed a high-resolution, helicopter-borne AeroTEM electromagnetic survey covering the previously unexplored southwestern corner of the Tamarack Project. The survey area comprises a section of the McFauld's Volcanic Belt interpreted to represent a continuation of the horizon associated with the recent nickel-copper-platinum group element (PGE) discovery of Noront Resources. The survey also provides a complementary data set to previously flown surveys to the east, which were responsible for the discovery of high-grade copper volcanogenic massive sulphide (VMS) mineralization on the Tamarack property in 2005.

The Tamarack property consists of 360 claim units (5,760 hectares) staked in two blocks covering the northern and southern stratigraphy of the McFauld's Volcanic Belt. In previous drilling by Probe Mines a 7.8 metre section of chalcopyrite-rich VMS mineralization grading 3.1% copper was intersected in the "A-zone", starting at a vertical depth of 50 metres. A second drill hole, collared 50 metres west and down dip from the discovery hole, intersected the A-zone at 97 metres vertical depth and returned 2.4% copper over 6.0 metres. Both intercepts also returned anomalous concentrations of zinc, gold and silver.

Results from the current survey will be used in conjunction with previous airborne and ground geophysical data to identify both VMS and Ni-Cu-PGE targets for a winter drilling program. Numerous untested targets occur in both the western and eastern claim blocks, and it is expected that the current survey will delineate additional conductors.

The McFaulds area is once again receiving considerable attention with the recent discovery of high-grade nickel-copper-PGE mineralization by Noront Resources, southwest and along strike of the Tamarack property. Results from hole NOT07-05 returned a 63.8m intersection of massive and net-textured sulphides in olivine-bearing peridotite grading 5.9% nickel, 3.1% copper, 2.9 g/t Pt and 9.8 g/t Pd; including a 3m interval grading 8.7% nickel, 10.9% copper, 41 g/t Pt and 14 g/t Pd.

Mantis can earn up to 51% of the Tamarack property through the option-joint venture agreement. As part of the agreement, Mantis is required to make exploration expenditures totaling $500,000 over a three-year term.
