ROCA - MAX Molybdenum Mine Production Update

TSX.V: ROK

VANCOUVER, Sept. 9 /PRNewswire-FirstCall/ - Roca Mines Inc. (TSX-V: ROK) ("Roca" or "the Company") has now received production reports and mill assays for the three months ended August 31, 2010.

During the period, production originated from the 780 stope where, as reported previously, estimates suggested that the initial material mined was expected to be in the 0.35% Mo range. The mine continues to focus on its sampling methods, grade and dilution control to deliver the best possible head grades. Management believes that its experience within the main zone and planning for other zones will deliver more robust operating performance in the future.

In August and September, the mine and mill were shut down for nine days as a result of an underground stope wall sloughing event between the 830 and 805 metre levels. An independent review was completed and highlighted that there were no issues with respect to re-entering the mine and that the event was contained entirely to the inactive, non-man-entry stope. Milling operations resumed on September 4, 2010.

The following table provides a summary of production data for the last three months:

Development crews are now advancing on the 725 metre level and operations continue to work toward the Phase II 1,000 tonne/day plan. The development of multiple stopes in the Phase II plan will reduce the impact of single-stope production difficulties encountered during 2009 and 2010.

Roca also announces the resignation of Ernest S. Peters from its board of directors who is leaving to devote more time to his other business interests. The Company thanks him for his years of service and wishes him success in his future endeavors.
