Creston Moly Intersects 61 Metres of 0.098% Molybdenum

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 27, 2010) - Creston Moly Corp. ("Creston" or the "Company") (TSX VENTURE:CMS) today announced the assay results for three diamond drill holes recently completed at its El Creston molybdenum property located in the state of Sonora, Mexico.

Highlights include:

  • Hole EC10-108 intersected 236.95 metre averaging 0.057% molybdenum commencing near surface which included a 61 metre section averaging 0.098% molybdenum. 
  • Hole EC10-105 intersected a near surface 97.75 metre section averaging 0.047% molybdenum including intercepts of 21.35 and 6.25 metres averaging 0.070 and 0.194% molybdenum, respectively. At depth a 52.15 metre section averaging 0.059% molybdenum that includes a 24.65 metre section averaging 0.097% molybdenum was intersected.
  • Hole EC10-107 intersected a 33.55 metre section averaging 0.078% molybdenum at the bottom of the hole.

The holes are from the Phase 3 segment of a four phase drill program initiated in February 2010 to advance the El Creston molybdenum deposit in the preparation of a feasibility study. The purpose of the drill program is to:

  • expand the El Creston deposit to the north
  • complete in-fill drilling in areas of limited drilling within the Creston Main Zone Resource
  • drill the Red Hill Shallow zone such that in conjunction with historic drilling it may be incorporated into 43-101 compliant resources and be included into the Creston Open Pit, and
  • complete drill testing for structural and hydrological information

"Drilling continues to produce favourable results," said Bruce McLeod, President & CEO. "Our goal of expanding the known resources of the El Creston molybdenum deposit is being achieved, and all results will be incorporated in a revised resource calculation, which we expect to be completed next month."

Drill Results

Hole EC10-105, located 70 metres north of Hole EC07-11 and 115 metres south of Hole EC10-104 was drilled to test mineralization continuity from holes EC07-11 toEC10-104. The results indicate above cut-off grade molybdenum to be continuous along section in areas in the original mine plan that were characterized as waste due to a lack of drilling. 

Hole EC10-107 was drilled to better outline the depth of the oxide zone on section. The hole was located 50 metres due north of Hole EC08-027 (262.70 metres averaging 0.066% molybdenum including 70.60 metres averaging 0.112 % molybdenum). Coincidental with the uppermost portion of the intercept in EC08-027 is an 88.15 metre portion averaging 0.15% copper. Hole EC10-107 intersected 17.75 metres averaging 0.17% copper at a depth of 64.05 metres. At the bottom of the hole there was also an intersection of 33.55 metres averaging 0.078% molybdenum that coincides with the top of the zone intersected in Hole EC08-027.

Hole EC10-108 was drilled to determine the continuity of the mineralization between Hole EC08-32 (160.55 metres averaging 0.106% molybdenum) located 65 metres to the southwest and Hole A-30 (88 metres averaging 0.098% molybdenum) located 60 metres to the northeast. At a depth of 39.65 metres Hole EC10-108 intersected 236.95 metres averaging 0.057% molybdenum including 61.0 metres averaging 0.098% molybdenum. The higher grade section occurs within an area that was designated as waste in the original mine plan due to a lack of drilling.

2010 Drilling

To-date in 2010, Creston has completed three phases of drilling totaling approximately 9,700 metres on its El Creston molybdenum deposit. The drilling has intersected significant above cut-off grade mineralization on the south, west and northern boundaries of the Main Zone resource outline. In addition, drilling on the Red Hill Zone 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. 

Creston has now commenced the 4th phase of drilling which consists of eight geotechnical holes for design purposes for the open pit in addition to two holes which will test the Red Hill Zone strike extension to Hole EC10-101 (94.55 metres averaging 0.057% molybdenum including sections of 36.60 and 12.20 metres respectively averaging 0.072 and 0.110% molybdenum). Results will be released as they become available. The drilling is part of a program being completed to advance the deposit towards the completion of a definitive feasibility study which is expected to be completed in the 2nd quarter, 2011.

Sampling and QA/QC

All of the samples collected were delivered by Company personnel to ALS-Chemex's prep lab in Hermosillo, Mexico where they were logged into the computer tracking system, crushed, split and a pulp sample prepared. The pulp sample was sent 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. In addition, Creston personnel routinely insert blanks and standards into the sample stream. Dave Visagie, P. Geo., a Qualified Person as defined by NI 43-101 is responsible for the technical information contained in this release.

El Creston Molybdenum Deposit

In 2009 a NI 43-101 compliant Pre-Feasibility Study ("PFS"), was issued by M3 Engineering & Technology Corporation of Tucson, Arizona ("M3"). Using a base case scenario of $15/lb Mo and $1.75/lb Cu M3 determined that the El Creston molybdenum deposit has an after-tax Net Present Value ("NPV") at an 8% discount rate of USD$306.02 million and an Internal Rate of Return ("IRR") of 20.2%. Creston is focusing on the completion of optimization projects designed to further improve the economics of the project by increasing the size of the resource and re-engineering certain key components of the project.
