ROCA - MAX Molybdenum Mine Development Update
======================================================================

Vancouver, British Columbia: Roca Mines Inc. (ROK: TSX-V) ("Roca" or
the "Company") provides the following update on development and
exploration activities at the MAX Molybdenum Project southeast of
Revelstoke, British Columbia.

Development of the MAX Molybdenum Mine has advanced significantly in
the past two months with initial production now targeted to begin in
approximately six weeks. Roca began its fast-tracked development of
the project only 14 months ago and the Company's contractors have met
numerous construction milestones in many areas, including;

Underground Development - Development of the decline and 25 metre (m)
sub-levels now provides access to the upper stopes. Ongoing
development work will provide access to lower stopes for subsequent
phases of mining. An electric-hydraulic long-hole production drill
will be mobilized to site on July 18, 2007 to commence production
drilling of the initial stopes. Ore from these stopes will be
available soon after commencing long-hole drilling.

Crusher / Mill & Concentrator - All of the heavy equipment, including;
crushers, feeders, primary grinding mills, regrind mill and thickener
tanks have been installed and are being wired to electrical controls.
All of the large motors and electrical systems have been delivered to
the site after inspection, repair and testing previously conducted
off-site. Where required, new liners, bearings, motors and other items
are also being fitted prior to startup. The mill and crusher
buildings' structural steel has been erected and cladding will be
applied shortly. Galleries between the various buildings are being
completed prior to the installation of conveyors.

Temporary Construction Camps - The Company has purchased and recently
completed the installation of a second construction camp providing more
flexibility for housing of its staff and contractors.

Key areas of the project that remain to be completed include the
following;

Electrical Systems Installation - An electrical power distribution
system for the MAX mine and mill is being completed allowing for
load-sharing and efficient power usage from three new 1,000 kW (each)
diesel gensets. The crusher and mill buildings are being readied for
internal power distribution to equipment and lighting.

Tailings Facility - After producing and stockpiling various crushed
borrow and rockfill materials for the past four months, construction of
the main (south) dam is now well underway. Excellent weather
conditions have aided in the organization and placement of the dam
materials. Starter dam elevations will be completed prior to the
targeted production date. Ongoing dam construction will progress to an
ultimate 2007 dam height by early fall.

Accelerated Phase II Development - The development of a second parallel
adit (tunnel) to the deposit is well underway. The second access will
immediately improve ventilation and lower operating costs of the
underground mine. The adits will also provide primary access for
long-term development and planned expansion phases of the MAX Mine.

The Company has also acquired an additional ball mill, currently
located in Spokane, Washington, for future expansion of the mill's
grinding circuit. This unit, a Harding 9.5 X 15, 700 hp ball mill will
be installed after production startup thereby providing flexibility and
additional capacity for the operation of the mill.

MAX 2007 Exploration Programs - The Company has completed the
development of an underground drill station from which a new
exploration program will be conducted. A Diamond drill will be
mobilized to the site in approximately two weeks to carry out an
exploration program that will focus on expanding the known molybdenite
resource at depth.

Roca plans to be the first new primary molybdenum producer in Canada.
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 and is a key alloy in the manufacture
of stainless and specialty steels, including pipelines and other
energy-related steel infrastructure.

Property Acquisition - The Company recently signed an option agreement
to acquire a 100% interest in 513 hectares contiguous with its Tin City
Property (see Company news release dated Dec. 1, 2006). Roca has paid
the vendor $12,300 on signing and, to complete the acquisition, must
pay an additional $100,000 and issue 50,000 common shares prior to June
5, 2009. The property is subject to a 2.5% Net Smelter Return, which
may be reduced to 0.5% upon payment of $1.5 million. This transaction
is subject to TSX Venture Exchange approval.
