Probe Mines Announces Updated Resource Estimate for Its Black Creek Chromite Deposit
- Massive chromite zone estimated to contain a Measured and Indicated Resource of 8,645,000 tonnes averaging 37.41% Cr2O3 and an additional Inferred Resource of 1,610,000 averaging 37.78% Cr2O3
Toronto, December 21, 2010 -- The Directors of PROBE MINES LIMITED (TSX-V: PRB) (Probe) are pleased to announce that the Company has received the updated mineral resource estimate for its 100%-owned Black Creek chromite deposit from Micon International Limited ("Micon"). The updated resource estimate, which meets the guidelines for reporting mineral exploration programs as set out in National Instrument 43-101, was based on an initial 15 diamond drill holes that tested the chromite horizon along approximately 200 metres (m) of strike length and to a vertical depth of approximately 175 m as well as an additional 10 holes drilled during the Phase III program. The Phase III drilling was successful in upgrading a portion of the Inferred Resources in the initial resource estimate to Measured and Indicated categories as well as extending the zone along strike and at depth. The program delineated an additional 115 m of strike length and identified chromite mineralization to 320 m depth. The Phase III drilling confirmed that the chromite zone is found at surface and, in places, is under less than 4 m of overburden, indicating it would be a likely candidate for open-pit extraction. Mineralization at Black Creek is dominated by three massive chromite layers, with subordinate amounts of banded, semi-massive and disseminated chromite found between and below the massive layers. The cumulative thickness of the mineralized zone averages approximately 65 m.
Dr. David Palmer, President of Probe states "We are very pleased with the results of the updated resource estimate. The Phase III program was successful in not only upgrading much of our previous Inferred resources into the Measured and Indicated categories, but also added to these categories and generated additional inferred mineralization. Drilling has shown the deposit to be of significant size and also of high quality and we have added considerable value to Black Creek with this updated resource estimate."

Summary of Black Creek Chromite Resources
Note: All tonnages have been rounded to the nearest thousand.
Mineral resources do not have demonstrated economic viability. The estimate of mineral resources may also be materially affected by other relevant factors or issues. There is no guarantee that the project will be placed into production. Micon is currently in the process of completing the updated NI 43-101 Technical Report supporting the estimate and the Technical Report will be filed within 45 days of this press release with SEDAR.
The mineralized material was classified into the Measured, Indicated or Inferred mineral resource category on the basis of a combination of the following factors: (a) confidence in the geological and mineralization continuity, (b) position of blocks in relation to the range of influence as defined by the variographic analysis and (c) and the search ellipse ranges
The Black Creek deposit Measured and Indicated resources have been categorized taking into account the search parameters in relation to variographic results, and the observed geological and mineralization continuity based on sectional interpretation. The known mineralization in the entire McFaulds Lake sill has been considered in the process of resource categorization.
