      ROCA - Drilling Intersects Significant Tungsten Mineralization
      Above MAX Mine
=======================================================================

Vancouver, British Columbia: 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% WO3 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.

Selected drill hole intercepts are tabulated below;

Sampling and logging of the drill holes was conducted under the
supervision of David Melling, P.Geo., a qualified person as defined by
NI43-101. The sampling program included quality control procedures, in
addition to internal quality control at the assay laboratory, ACME
Analytical of Vancouver, BC an ISO 9001:2000 accredited laboratory.
