Creston Moly Intersects 118.95 Metres of 0.136% Molybdenum

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 13, 2010) - Creston Moly Corp. ("Creston" or the "Company") (TSX VENTURE:CMS) today announced the assay results of three diamond drill holes recently completed from its Phase Three drill program at the El Creston molybdenum property located in the state of Sonora, Mexico. The holes, part of a seventeen drill hole program totaling approximately 2,500 metres in length, were drilled in close proximity to the northern boundary of the Main Zone Resource.

Highlights include:

  • Hole EC10-106 intersecting a 146.40 metre section averaging 0.116% molybdenum including a 118.95 metre section averaging 0.136% molybdenum
  • Hole EC10-104 drilled to the immediate north of the current resource outline intersecting an 88.45 metre section averaging 0.045% molybdenum including a 43.05 metre section averaging 0.053% molybdenum
  • Hole EC10-103 drilled on the northern boundary of the resource averaging 0.038% molybdenum over 99.9 metres including an 18.30 metre section grading 0.107% molybdenum

"The Company continues to advance the El Creston molybdenum deposit in the preparation of a definitive feasibility study as drilling continues to demonstrate that the resource is larger than originally estimated," said Bruce McLeod, President & CEO of Creston. "The three holes released today are from the recently expanded northern portion of the deposit. Hole EC10-106 encountered much higher grades than the 2009 resource average, and when combined with all of the 2010 drilling data should positively impact our revised resource which is due in the Q4, 2010."

Hole EC10-103 is located on the northern boundary of the resource outline, approximately 140 metres north of Hole GT10-007 (64.05 metres averaging 0.071% molybdenum), and 100 metres west of Hole EC10-71 (102 metres averaging 0.069% molybdenum). Prior to the 2010 drill program the area, due to a lack of drilling, was categorized as below economic cut-off grade (less than 0.037% molybdenum equivalent) in the mine plan. Hole EC10-103 intersected a 99.9 metre section averaging 0.038% molybdenum and includes sections of 11.60 and 18.30 metres averaging 0.072% and 0.107% molybdenum, respectively. 

Hole EC10-104 is located immediately adjacent to the north of the resource outline, approximately 60 metres to the northwest of Hole EC10-068 (134.20 metres averaging 0.040% molybdenum including 28.80 metres averaging 0.055% molybdenum). Commencing at a depth of 18.3 metres, Hole EC10-104 intersected an 88.45 metre section averaging 0.045% molybdenum including sections of 9.15 and 43.05 metres averaging 0.104 and 0.053% molybdenum, respectively. The hole bottomed in mineralization with the final 3.20 metres averaging 0.070% molybdenum.

Hole EC10-106 was collared 100 metres north of Hole EC10-67 (an angled hole drilled due north that averaged 0.091% molybdenum over 198.25 metres including a 94.55 metre section averaging 0.151% molybdenum). Commencing at a down hole depth of 45.75 metres, Hole EC10-106 intersected a 146.60 metre section averaging 0.116% molybdenum including a 118.95 metre section averaging 0.136% molybdenum. 

All three holes show the zone to be open to the north with above cut-off grade mineralization occurring within and below the proposed pit with Hole EC10-106 intersecting significant molybdenum up to 130 metres below the 2009 proposed pit.

2010 Drilling

Since the start of 2010, Creston has completed three phases of drilling totaling approximately 9,700 metres in length at its El Creston molybdenum property. The drill programs have intersected significant above cut-off grade mineralization on the south, west and northern boundaries of the Main Zone Resource boundary. In addition drilling at 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 which would include both the El Creston Main Zone and portions of the Red Hill Zone. 

The Company is currently undertaking a Phase Four drill program consisting of 8 geotechnical holes to be used in the design of the proposed open pit. In addition, two holes are being drilled into the Red Hill Zone to test the along strike extension to Hole EC10-101 (94.55 metres averaging 0.057% molybdenum including sections of 36.60 and 12.20 metres averaging 0.072% and 0.110% molybdenum, respectively). Results will be released as they become available. The drilling is part of a $4 million program being completed to advance the project towards the completion of a definitive feasibility study. In addition to drilling, Creston has completed geophysical surveying and other ground work, the results of which have been previously released.

The reserves were completed by Mine Development Associates, Reno Nevada using block modeling of drill core assays.

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%.

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.
