Creston Moly Corp.: El Creston Molybdenum Property Returns Rhenium Values

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 24, 2011) - Creston Moly Corp. ("Creston" or the Company") (TSX VENTURE:CMS) announces that anomalous rhenium (Re) values have been detected in selected drill core samples from its El Creston Main Zone molybdenum deposit, located in the state of Sonora, Mexico. A total of 22 samples from various locations within the deposit were analyzed for rhenium, and all returned anomalous values. Six samples assayed greater than 0.40 gpt rhenium with a maximum value returning 1.25 gpt. In general, the rhenium values correlate well with molybdenum. Additional sampling of drill core is presently being undertaken. A full table of all samples follows.

Nickel-based super alloys for use in jet engines contain up to 6% of rhenium, making jet engine construction the largest use for the element, with chemical industry catalytic uses being next-most important. Because of the low availability relative to demand, rhenium is among the most expensive industrial metals, with an approximate price of US$4,350 per kilogram.

"The potential for rhenium credits at El Creston will need to be fully evaluated," said Bruce McLeod, President & CEO of Creston. "However these initial assay results are very encouraging and rhenium has the potential to be an economic contributor to the overall value of the project."


In early 2011, 22 pulp samples, selected from a series of holes located within the Creston Main Zone, were sent to ALS Chemex Labs for rhenium analysis using a 4 acid digestion with analysis by Inductively Coupled Plasma (ICP). The samples represented various grade combinations of molybdenum and copper. The results of the 22 samples submitted are listed below. Maps showing the sample locations are available at or click the link below to view the map showing the drill hole locations.

2010 Drilling

In 2010, Creston completed four phases of drilling resulting in the completion of 45 Exploration and 17 Geotechnical Holes respectively totaling 7,835 and 3,085 metres on its El Creston molybdenum deposit. The drilling intersected significant above cut-off grade mineralization along the south, west and northern boundaries of the Main Zone resource outline. In addition, drilling on the Red Hill Zone has encountered significant near surface molybdenum and/or copper mineralization that could potentially be mined as part of a larger open pit that would include both the El Creston Main and Red Hill Zones. 

Sampling and QA/QC

All of the pulp samples were collected from the Companies warehouse and delivered by Company personnel to ALS-Chemex's prep lab in Hermosillo, Mexico where they were logged into the computer tracking system, and forwarded to ALS Chemex's laboratory in Vancouver, B.C for analysis by Inductively Coupled Plasma. ALS-Chemex is an ISO/17025 accredited laboratory. ALS-Chemex monitors quality control through the introduction of blanks, standards and duplicate sampling. Dave Visagie, P. Geo., a Qualified Person as defined by NI 43-101 is responsible for the technical information contained in this release.

2011 Drill Program

Currently the Company is completing a 15 hole drill program totaling 2,100 metres in length that will test the Main Zone along the west, north and east boundaries with the purpose of re-classifying those inferred resources to a measured or indicated status so that they may be included in the feasibility study scheduled to be released midyear.
