VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 8, 2008) - Creston Moly Corp. ("Creston" or the "Company") (TSX VENTURE:CMS) is pleased to announce the results of 12 holes from the recently completed infill drill program on the Main Molybdenum Zone of its 100% owned Creston Molybdenum deposit located in Sonora State, Mexico. The program consisted of 52 holes totaling 15,646 metres.

Analytical results are tabulated below. Drill hole locations are shown in the accompanying location map. The map is also available at http://www.crestonmoly.com/i/maps/Dr... .

As shown in the drill plan map, the holes reported in this news release were drilled in three sectors of the deposit:

1) Northern sector (Holes EC08-032 and 037);

2) Central sector (Holes EC08-033,034,035,036, 039 and 041); and

3) Southwestern sector (Holes EC08-030, 038, 040, 042).

In the northern sector, holes EC08-032 and EC08-037 encountered strong, continuous and high grade mineralization in areas previously interpreted as lying outside the northern boundary of the deposit. Hole EC08-037, drilled vertically, penetrated a 175.69 m interval averaging 0.08% Mo. Hole EC08-032, drilled at an angle of -60 degrees on a northerly bearing, cut 251.9 m averaging 0.12% Mo. Based on the results from these two holes, the Main Zone deposit remains open to the north.

Results from holes drilled within the central sector of the deposit returned strong mineralization throughout, including intervals ranging from 0.08% Mo over 249.65 metres in hole EC08-034 to 297.18 m of 0.12% Mo in Hole EC08-033. The easternmost drill hole reported in this news release (EC08-041), cut a continuous high grade interval averaging 0.16% Mo over a core length of 209.52 m. This intersection confirmed the presence of a well defined high grade zone, hosted by hydrothermal breccias, within the eastern half of the Main Zone.

Holes drilled in the southwestern sector encountered weak to moderate grade molybdenum mineralization (0.03% Mo over 93.2 m in hole EC08-038 to 0.07% Mo over 210.45 m in hole EC08-040) and significant intervals of predominantly chalcocite mineralization which include 139.77 m of 0.43% Cu in hole EC08-030 and 118.9 m of 0.31% Cu in hole EC08-038.

Mr. Jonathan George, President and CEO, comments: "We are very pleased to have defined a high grade zone in the eastern portion of the deposit as well as an unexpected expansion of the deposit to the north. With these results we look forward to the completion of a new independent resource estimate to be undertaken during the summer."

Sampling and QA/QC

Drilling at El Creston is carried out by Layne Drilling employing two wireline rigs that recover HQ core. Where necessary the core is reduced to NQ size. The core is transported to a secure facility at the nearby Opodepe camp where it undergoes geotechnical and geological logging. Prior to delivering the core to ALS Chemex preparation lab in Hermosillo, the core is photographed and all mineralized zones are photographed in detail. Blanks, standards, field and coarse reject duplicates, and pulp duplicates are inserted in the stream of samples prior to delivery to the preparation lab.

Based on recommendations by Mine Development Associates ("MDA") of Reno Nevada, the entire core is sent to the preparation lab in Hermosillo. MDA is the independent consulting firm that has been retained to oversee QA/QC procedures and to carry out the updated resource estimate of the El Creston Main Zone following the completion of the ongoing drill program.

The rationale for not sawing the core and retaining half of the sample is based on two considerations: 1) portions of the molybdenite mineralization at El Creston occur as loosely bound coarse flakes and clusters and 2) there is evidence of a nugget effect in parts of the deposit. Thus, the sampling of the entire core prevents or minimizes the loss of molybdenite due to core handling, sawing, and washing. In addition, keeping the entire core maximizes the sample volume, which should minimize any nugget effect and more accurately represent the mean grade of the deposit.

Sample preparation in Hermosillo consists of crushing the whole interval to minimum of greater than 70% of the crushed sample passing a 2 mm screen and then splitting the -2 mm crushed sample to produce a representative split of 1,000 grams. Each 1,000 gram sample is then pulverized to at least 85% passing -75 microns.

The pulps are then shipped to ALS-Chemex in North Vancouver to be analyzed for total Mo% and Cu% using a four acid digestion and ICP-AES (Atomic Emission Spectroscopy) finish. Samples from the oxide zone are sent to Skyline Labs in Tucson to be analyzed for molybdenum oxide.

The drill program at El Creston is being supervised by Fabrizio Colombo, PhD, P. Geo.
