DENTONIA ANNOUNCES 2.01% TUNGSTEN TRIOXIDE ROCK PANEL SAMPLE ON KNIGHT INLET AREA CLAIMS
10/14/2009 [ACCESSWIRE]
Dentonia Resources Ltd. ("the Company") is pleased to announce the results of a rock panel sample taken from the tungsten showing on the 29,603-hectare Knight Inlet area claims.
25 samples assayed by the X-Ray Fluorescence/Fusion method averaged a value of 1.59% tungsten ("W"), which equates to 2.01% tungsten trioxide ("WO3").
On September 21, 2009 a rock panel sample of approximately 100kg was taken from the face of the previously reported tungsten skarn showing. The rock sampling and subsequent transport were carried out under the supervision and custody of James A. Turner, P. Geo. A photograph of the panel area of approximately 1m2 is posted on the Company's website (www.dentonia.net).

The rock sample material was placed in five pails, which were sealed and flown to Campbell River by helicopter, then transported by vehicle to Acme Analytical Laboratories ("Acme") in Vancouver, B.C. The pails were unsealed by Acme, and five random, approximately 1kg, rock samples were taken from each pail and assayed by the X-ray Fluorescence/Fusion method.
The average of the 25 assays reported by Acme was 1.59% W, which equates to 2.01% WO3.

The panel rock sample and X-Ray Fluorescence/Fusion was undertaken to assist in eliminating the variances caused by the nugget effect of previous sampling and assaying. The Company is planning a small bulk sample as a follow-up to this rock panel sample.
Assay procedure
Twenty-five 250g samples of minus 150 - 200 mesh were roasted to determine the "Loss on Ignition". Five grams of the roasted sample is fused in a platinum-gold crucible with a commercial lithium tetraborate flux. The molten material is cast in a platinum mold. The fusion disks are analyzed using a Siemens SRS-3000 sequential X-Ray Spectrometer with a chromium tube for 11 elements, which include CaO, K2O, P2O5, SiO2, Al2O3, MgO, Na2O, Fe2O3, TiO2, MnO, Ba and W. Only the W values are reported here. All elements analyzed are corrected for absorption effect, enhancement effect, line overlap, background correction and Loss on Ignition. The calibration curves for whole rock analysis are setup using synthetic and commercial standards with certified analytical data. Every 20-fusion disks prepared include one in-house or commercial standard and one repeat sample. Every 20 samples analyzed include 2 commercial standards. The lower limit of detection (or 2 times standard deviation) for whole rock analysis is 0.01% except for SiO2, which is 0.1%.

The perspective target rocks are at least 164m wide. The main mineralized skarn is 32m wide. The main tungsten mineral is scheelite (80.6% tungsten trioxide).
The Knight Inlet claims are located approximately 80kms north of Campbell River, mainland BC. Access is by boat, seaplane or helicopter to Fraser Bay at the head of Loughborough Inlet. The tungsten discovery area can be reached either by helicopter or by an 11km-logging road inland from Fraser Bay.

About Tungsten ("W")
Tungsten prices and many tungsten statistics are quoted in units of tungsten trioxide ("WO3"). The short ton unit, used in the United States, is 1% of a short ton (20lbs) and tungsten trioxide is 79.3% tungsten.
Tungsten trioxide, recently, had a price range of between US$32/kg and US$20/kg (US$15/lb and US$9/lb) and is currently at the lower end of this range.
Tungsten has a wide range of industrial uses. The largest use is as tungsten carbide in cemented carbides. Cemented carbides (also called hard metals) are wear-resistant materials used by the metalworking, mining and construction industries. Tungsten metal wires, electrodes and/or contacts are used in lighting, electronic, electrical, heating & welding applications. Tungsten is also used to make tool steels, wear-resistant alloy parts & coatings, super alloys for turbine blades and heavy metal alloys for armaments, heat sinks & high-density applications, such as weights & counterweights. Chemical uses of tungsten include catalysts, inorganic pigments & high-temperature lubricant.
