ROCA-Molybdenite Concentrate Shipments Commence

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 11, 2007) - Roca Mines Inc. (TSX VENTURE:ROK) ("Roca" or "the Company") announces that shipments of molybdenite concentrates have recently commenced from its MAX Molybdenum mine, located 60 kilometres southeast of Revelstoke, British Columbia.

To date, shipments totaling 37,800 lbs. of contained molybdenum have been purchased by Derek Raphael and Co., a UK-based molybdenite concentrate trading company, through its North American representative, W.G. Cook Ltd. Payment for these shipments has also commenced to the Company's account.

Mill and concentrator operations at MAX are ramping up to capacity with the processing of stockpiled development material located adjacent to the mill facility. Once process optimization is completed, operations will continue utilizing direct feed ore-grade material from the underground mine. To date, the mill has attained approximately 94% availability. The concentrator has achieved recoveries up to 96.5%, with average recoveries through startup of approximately 85% from the stockpiled material.

The permitted PHASE I mine plan for MAX will focus on the deposit's high-grade zone containing 280,000 measured and indicated tonnes grading 1.95% MoS2 (refer to T.N. Macauley's 43-101 compliant technical report dated September 2004 available via SEDAR). Molybdenum currently trades in the US$32-33/lb. range.
