Creston Moly Intersects 67.1 Metres of 0.134% Molybdenum

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 9, 2010) - Creston Moly Corp. ("Creston" or the "Company") (TSX VENTURE:CMS) today announced the assay results of five diamond drill holes completed from its Phase Three drill program, at the El Creston molybdenum property located in the state of Sonora, Mexico. The five holes, the first of a 2,500 metre program, were drilled in the Red Hill Shallow Zone located to the immediate southwest of the Main Zone Resource boundary. 

Highlights include:

  • Hole EC10-98 drilled in the centre of the zone averaged 0.134% molybdenum over 67.1 metres
  • Hole EC10-101 drilled in the northwest portion of the zone intersected 94.55 metres averaging 0.057% molybdenum 
  • Hole EC10-102 drilled along the zone's western margin intersected 27.85 metre section averaging 0.095% molybdenum.

"We are extremely pleased with these drill results and all of our results to date," said Bruce McLeod, President & CEO of Creston. "The purpose of the Phase Three drill program is to complete infill and definition drilling of the Main Zone and determine the continuity of mineralization within the Red Hill Shallow Zone. The data collected will aid in the goal of re-designing a larger open pit to incorporate the Red Hill Shallow Zone and the Main Zone."

Drill Results

To date, the drill results have traced the Red Hill Shallow Zone for 400 metres along the trend with the zone open to the northwest. Width is variable to in excess of 150 metres while thickness varies to in excess of 90 metres. Initial studies indicate that both the Creston Main and Red Hill Zones may be mineable from one open pit potentially adding to the resource base and reducing waste stripping.

EC10-98 located approximately 20 metres north of Amax Hole A-8 (56 metres averaging 0.096% molybdenum) was drilled due to poor core recovery from Hole A-8 that could have resulted in a loss of molybdenum. Hole EC10-98 intersected a 67.1 metre section averaging 0.134% molybdenum commencing at a depth of 15.25 metres. 

Hole EC10-99 located approximately 80 metres to the southeast of Hole EC10-98, was completed in an area where previous drill results could not be verified. Commencing at a depth of 48.8 metres, the hole intersected a 39.65 metre section averaging 0.090% molybdenum.

Hole EC10-100 is located on the eastern edge of the Red Hill Zone. The hole intersected anomalous copper values throughout its length. Results include 24.4 and 9.15 metre sections assaying 0.15 and 0.16% copper, respectively. The best molybdenum intercept averaged 0.047% molybdenum over 6.10 metres. 

Hole EC10-101 (an angle hole drilled due north) is located 10 metres to the north of Hole EC08-59. Hole EC08-59 (an angle hole drilled due south) intersected 48.20 metres averaging 0.058% molybdenum commencing at a down hole depth of 48.20 metres and 16.02 metres averaging 0.103% molybdenum commencing at 152.10 metres. Hole EC10-101, drilled to the north to test for the continuity of mineralization, intersected a 94.55 metre section averaging 0.057% molybdenum commencing at a down hole depth of 36.6 metres. Within the intercept there are higher grade intercepts of 36.60 and 12.20 metres averaging 0.076 and 0.110% molybdenum, respectively. 

Hole EC10-102 was drilled to test the projection of the mineralization of the zone intersected in Hole EC10-94 (85.40 metres averaging 0.087% molybdenum commencing at surface). The hole, located approximately 60 metres to the south of EC10-94, intersected a 27.85 metre section averaging 0.095% molybdenum commencing at a depth of 24 metres.

2010 Drilling

Since the start of 2010, Creston has completed two phases of drilling totaling 7,200 metres in length at its El Creston molybdenum property. The programs have intersected significant above cut-off grade mineralization on the south, west and northern boundaries of the Main Zone resource outline. 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 and Red Hill Zones. 

The Company is currently conducting a Phase Three drill program comprised of infill and exploration drill holes and is preparing a Phase Four drill program that will include two exploratory holes and eight structural holes totaling 2,000 metres in length. Data collected from the programs will be used in the design of a proposed open pit (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. 

El Creston Molybdenum Deposit Main Zone

The El Creston molybdenum deposit contains the following Mineral Reserves and in-pit inferred resources at a 0.037% Mo equivalent* cut-off grade:

Category   Tonnes (000's)   Mo (%)   lbs Mo (000's)   Cu (%)   lbs Cu (000's)
Proven Reserves   44,736   0.079   78,024   0.053   52,217
Probable Reserves   101,968   0.076   171,924   0.047   106,614
Proven and probable reserves   146,705   0.077   249,948   0.049   158,831
In-pit Inferred Resources   8,718   0.065   12,464   0.063   12,158

*Mo-equivalent cut-off: Mo%+(Cu/7.5). 

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.
