      ROCA - MAX Property Exploration Update
=======================================================================

Vancouver, British Columbia: Roca Mines Inc. (ROK: TSX-V) ("Roca" or
"the Company") provides the following update on exploration activities
at the MAX Property near Revelstoke, British Columbia.

Summary
- Underground drilling results confirm new feeder zone and refine deep
targets;
- Geological interpretation highlights multi-phase intrusive events and
large-scale intrusions at depth;
- Surface exploration drilling has commenced on a biogeochemical
molybdenum anomaly near the MAX Mine Portal area;
- Surface drilling to be conducted on a large-scale tungsten zone
identified previously by others and significantly expanded by Roca in
2006.

Underground (2007) Final Drilling Results

Five Diamond drill holes totaling approximately 4,800 m were completed
in 2007 (see Company's News Release dated February 7, 2008).  All holes
were collared from a common underground drill station within the No.1
Adit, east of the deposit currently being mined.  The Company has now
received final assays for drill holes MX07-04 and -05.

Results from the five holes have identified extensions to known
mineralization and indicate the potential for additional porphyry
systems at depth.  As previously reported, hole MX07-03 drilled at -65
degrees on Mine Section 8 below the eastern margin of the known
resource, intersected a number of narrow, well mineralized zones,
interpreted to represent sub-vertical feeders within a well recognized
pre-, inter-, and post mineral structure known as the "Z" Fault zone.

The lower half of Hole MX07-03 (previously partially reported) and Hole
MX07-04, oriented along the lower southwest margin of the MAX deposit
were both variably mineralized over much of their lengths and will help
to guide future exploration but are not considered significant at this
time.

Hole MX07-05 oriented to test the area immediately adjacent on Mine
Section 9, shows that the narrow feeders coalesce into a larger
cohesive mineralized zone, open to depth and open laterally.  This new
zone extends some 200 m below the boundary of the known MAX resource
and will be a focus of further underground exploration drilling in the
future. 

 
Core sampling of Drill Hole MX07-05 returned the following selected
assay results;


Drill Hole #   From (m) To (m)   Interval (m)   Mo (%)   MoS2 (%)
MX07-05        136.0    307.0    171.0          0.104     0.17  
Including      136.0    139.0      3.0          0.491     0.82  
Including      207.0    211.5      4.5          0.286     0.48  
Including      238.5    263.0     24.5          0.389     0.65  
                                                                
               327.0    367.5     40.5          0.126     0.21  
Including      357.0    367.5     10.5          0.329     0.55  


Relative to the trend of the MAX Mine HG production zone, the true
width of the drill intervals is estimated to be 30% of the intervals
shown above.

Roca's underground exploration drilling has thus far intersected strong
hydrothermal alteration, indications of several intrusive phases, and
significant multiple episodes of mineralization below the MAX deposit.

Detailed petrographic studies by previous workers also concluded that
there are at least four intrusive pulses, and a highly repetitive
mineralizing event at MAX.  The size of the inferred system is also
significant.  It is estimated that a pluton at depth could have a
diameter of roughly 1,000 m, based on the width of the contact
metamorphic aureole on surface, whereas the intrusion at the centre of
the deposit is roughly 200 m in diameter.  This suggests that the known
deposit may have other zones and/or other deposits that are not yet
discovered.

Indications of a larger intrusion at depth, significant molybdenite
intercepts in Holes MX07-03 and -05, as well as a repetitive
mineralizing event provide compelling evidence for additional porphyry
mineralization below the MAX deposit.  Additional exploration drilling
will be collared from new locations within the mine workings in the
future.

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.

Surface Exploration Drilling of Molybdenum and Tungsten Targets
Commences

Roca has mobilized a Diamond drill to the MAX project to commence
exploration drilling on two primary surface targets on the MAX
Property.  The targets are in close proximity to the MAX Molybdenum
Mine but represent potentially separate mineralized zones, including;

1. A newly discovered surface molybdenum biogeochemical anomaly (150 m
X 350 m) centered approximately 500m west of the MAX mine portal area
was identified during a survey conducted by the Geological Survey of
Canada's (GSC) Targeted Geoscience Initiative -- 3 (TGI-3) in late
2007. This anomaly was not previously identified because it lies beyond
the historical limits of a soil geochemical sampling grid, and in an
area of no previous drilling. The biogeochemical survey also identified
the surface expression of the MAX deposit itself, providing
confirmation of the potential success of this targeting technique.  An
additional geochemical anomaly was discovered approximately 350m
southeast of the MAX deposit and a soil sampling grid will be
established at that location this summer.

2. The Ridge and Upper Ridge Tungsten zones located approximately 1.2
km southwest of the MAX mine portal area were most recently explored by
others in 1979, including a total of three Diamond drill holes.  Of
interest, drill hole 79-13 intersected 56 feet (17.3 m) of 0.395%
scheelite (WO3) (see Company's news release dated December 12, 2006).
The tungsten area was significantly expanded by Roca in 2006 when the
Company's prospectors discovered scheelite mineralization southeast of
the Ridge Zone and hosted in low-sulphide, garnet-rich skarn boulders
and outcrop.  With the addition of the Upper Ridge Zone, the strike
length of tungsten mineralization as indicated by all of the outcrop
sampled to date and encompassing all zones now totals 1,450 m in length
and extends over a vertical range of 600 m.  Roca's initial drill
program will test the size and potential of this large mineralized and
near-surface zone.

Tungsten is an essential metal, noted for its hardness and high-melting
point. It is used primarily in cemented carbide and high-speed steel
tools for the construction and mining industries and for general wear
protection of steel alloys.  Like molybdenum, tungsten metal and
concentrates are currently trading at or near record high prices.
