Progress report on the Creston Molybdenum project Sonora, Mexico



    VANCOUVER, Dec. 4 /CNW Telbec/ - Creston Moly Corp. ("Creston" or the
"Company") (TSX-V: CMS) is pleased to announce the following update on its
Creston Molybdenum project in Sonora, Mexico.
    To date, 11 diamond drill holes, comprising 2,650 metres, have been
completed on and peripheral to the "main zone" utilizing HQ diameter core.
Highly mineralized intervals have been observed within the confines of the
main zone.
    The Company submits samples to ALS Chemex, Hermosillo for preparation,
after which pulps are shipped to their North Vancouver, B.C. lab for analysis.
The turn around time for results is now up to two months due to extremely high
sample submission volumes being experienced by the industry as a whole.
    Complete analytical results for the initial six holes of the ongoing
drill program are expected shortly.
    Further, an additional rig under contract with Layne Drilling of
Hermosillo has commenced drilling on the main zone. Jonathan George, President
and CEO states "We are extremely pleased with the performance and
professionalism of Layne Drilling to date, and are fortunate to have secured a
second rig to accelerate our program."
    Over the next few months, the Company will complete an additional
30-40 drill holes within the Creston main zone with the purpose of upgrading
the 43-101 compliant inferred resource of 84,221,000 tonnes grading 0.076% Mo
(141.1 million lbs Mo) to the indicated category which presently contains
170 million lbs of molybdenum grading 0.083% Mo (molybdenum presently trades
at $33.00 per pound).
    Upon completion of the in-fill drill program, Mine Development Associates
(MDA) of Reno, Nevada will undertake a new resource calculation enabling the
Company to proceed with a feasibility study for mine development.
    Additional zones outside the main zone are also to be evaluated. The Red
Hill Zone, located approximately 300 metres southwest of the main zone, has
been interpreted as the faulted extension of the main zone, and could add
substantial tonnage to the project.
    The newly discovered "Alejandra Zone" located 1.5 km northeast of the
main zone extends for approximately 2 kilometres and represents a prime target
for exploration.
    Negotiations with the Ejido of Opodepe for surface rights covering the
Creston Deposit, have gone exceedingly well with formal approvals expected in
early 2008.
    As part of its ongoing commitment to the people of Opodepe, the Company
will assist in establishing water reservoirs for livestock, maintain & upgrade
medical facilities and has recently "adopted" the community school. Talks with
owners of nearby water rights have also been initiated and are ongoing.
    Mr. George states "with the exception of slow assay turn around times,
every aspect of the Creston Project is proceeding smoothly. In just six
months, we've established an excellent rapport with the community, hiring
mostly locals. Two drills are turning 24 hours a day and new molybdenum zones
have been discovered giving this project significant upside potential."
    The Company also wishes to emphasize that it is not aware of any material
change in its affairs that would account for the recent trading activity in
its shares.

    1. Mineral resources which are not mineral reserves do not have
       demonstrated economic viability. The estimates of mineral resources
       may be materially affected by environmental, permitting, legal, title,
       taxation, sociopolitical, marketing or other relevant issues.
    2. The quantity and grade of reported inferred resources in this
       estimation are conceptual in nature and there has been insufficient
       exploration to define these inferred resources as an indicated or
       measured mineral resource and it is uncertain if further exploration
       will result in upgrading them to an indicated or measured mineral
       resource category.
    3. The mineral resources referred to herein have been estimated in an
       NI 43-101 compliant technical report (the "P & E Report") prepared for
       the Company in March 2007 by independent qualified persons Eugene
       Puritch, P. Eng. and Dr. Wayne Ewert, P. Geo. of P&E Mining
       Consultants Inc. The P & E Report is available at www.sedar.com.
