ROCA-MAX Molybdenum Mine Update

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 10, 2007) - Roca Mines Inc. (TSX VENTURE:ROK) ("Roca" or "the Company") announces the following update on activities at its MAX Molybdenum Mine.

Roca's third primary diesel genset arrived on Wednesday September 5, 2007 and is being load tested together with the two other units. Once completed, the mine/mill power distribution system will be energized and various rental genset units used during construction will be phased out.

The jaw crusher has successfully completed the first phase of testing with no significant problems identified; minor adjustments will be made prior to testing the completed crusher facility. The cone crusher and associated conveyors will be similarly tested over the coming days. As described previously, initial testing of the crusher facility will use waste rock and low-grade material leading to the crushing of stockpiled ore-grade material located nearby.

By mutual agreement, the Company announces the termination of its consulting agreement with Mr. John Kiernan, P. Eng. as its Vice President, Mining effective September 7, 2007.
