ROCA Reports Temporary Shutdown at MAX Mine

TSX.V: ROK

VANCOUVER, Aug. 26 /PRNewswire-FirstCall/ - Roca Mines Inc. (TSX-V: ROK) ("Roca" or "the Company") announces that production at its MAX Molybdenum Mine has been temporarily suspended due to underground stope wall sloughing at the 830mL and 805mL.

Increased wall sloughing activity has been observed in these areas over the past 24 hours. Rock mass conditions at these levels were previously observed to be less than that generally seen in the mine and a number of changes were made to the mine plan and scheduling as a result.

Management has now directed that no production or development activity shall take place below the 850mL of the mine until current stope wall conditions stabilize. This cautious step will protect the safety of mine workers and equipment from unforeseen ground conditions. Past experience suggests that ground stresses will be redistributed in the rock mass and that conditions should improve over the next 48 hours. Ongoing monitoring and observation will establish a more accurate timeline to re-enter the area in the coming hours and days.

It is important to note that the stope wall sloughing is active only in the stoping area and not in any manned-access; therefore, there is no impact to the ramp or other parts of the mine.

Management uses an observational approach to assess rock mass conditions and stability and the Company's underground geotechnical consultants will assist in a review of the recent events. Subject to conditions improving as described above, current plans are to re-enter the area on Sunday August 29, 2010 to begin dewatering and then to re-commence production on September 2, 2010.
