ROCA-MAX Molybdenum Mine Update

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.
