ROCA - MAX Molybdenum Mine Production Update

VANCOUVER, June 10 /CNW/ - Roca Mines Inc. (TSX-V: ROK) ("Roca" or "the Company") has now received production reports and mill assays for the three months ended May 31, 2010.

The MAX Molybdenum Mine continues to operate at targeted Phase I throughput rates with good efficiency and excellent recovery. Ore production from the single-stoping areas has returned average mine-diluted head grades that remain below targets in the period.

During the period, production originated from the 805 stope and, as reported previously, estimates for that level suggested higher grades than were realized. However, during the month of May 2010, production commenced from the 780 stope. The initial material mined on 780L was expected to be in the 0.35% Mo range, and is anticipated to improve as the stope is expanded. Stoping has continued on 780L and current production suggests improved grades over the average shown below.

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

Development crews are advancing on the 750 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.

In April, the Company received an amendment to its operating permit M-226, approving an increase in production to its planned Phase II, 1,000 tonnes/day throughput rate from the British Columbia Ministry of Energy, Mines and Petroleum Resources (BC-MEMPR).
