    VANCOUVER, July 29 /EMWNews/ - Roca Mines Inc. (ROK:

TSX-V) ("Roca" or "the Company") reports that its recent surface

diamond-drilling program conducted on the southern portion of the Ridge

Tungsten Zone at the MAX project has intersected significant intervals and

grades of tungsten mineralization. Combined with past work, the recent

results suggest great potential for a new tungsten resource to be defined

at MAX based on the exceptional continuity observed. The mineralization was

intersected above and in close proximity to the producing MAX Mine. At

their lowest point, the tungsten intervals are located approximately 650

metres (m) above the Main Haulage Adit level of the MAX Mine.



    Roca's initial program was designed to test downdip continuity as well

as for potential grade increase closer to the MAX intrusions. Each of the

four drillholes successfully intersected tungsten mineralization occurring

as scheelite in garnet diopside-rich skarn layers. In addition, grades

appear to be increasing with depth as evident in Drillhole MM-08-07 which

intersected 0.504% WO3 over 13.10m (estimated 12.5m true thickness) at a

downhole depth of 167.80m.



    Previous surface mapping and prospecting by ROCA extended the zone of

scheelite/skarn mineralization over a strike length of 1,400m. Recent

drilling took place on the southern portion of the area where three

widely-spaced and shallow holes were drilled in 1979 (see Roca news release

dated Dec 12, 2006). This recent drill program also discovered a new, lower

mineralized skarn band, including; MM-08-05 which returned 0.593% WO(3)

over 3.17m (estimated to be true thickness) at a depth of 220.62m.



    The continuity of the mineralized zones indicated by drilling and the

sizeable footprint of the mineralization on surface over substantial

distances suggests the potential for a large-scale tungsten resource

located immediately above the MAX Mine. Additional diamond drilling to

assess the potential of a tungsten resource, obtain metallurgical samples

in addition to possible near-term development with an underground raise are

currently being planned. Existing infrastructure at the MAX Mine is well

suited to the potential development of a tungsten resource.
