Tiex Inc. Reports increased grades with Sonic drilling
KELOWNA, BC, May 25 /PRNewswire-FirstCall/ - Tiex Inc.("Tiex" or the "Company") (TSX-V:TIX ) is pleased to announce increased grades from a small pilot program of sonic drilling on its 100% owned Gold Creek property located at Likely, B. C.

As shown above in the Drilling Highlights, the 2010 hole GC 10-02 which was drilled in between the 2008 holes GC08-02 and GC08-03 has increased the grade (g/t) from the 2008 results due to the increased drill core recovery of the Sonic Drilling method.
The 2010 program of 139.94 metres of sonic drilling in two holes at the Gold Creek property confirmed the presence of gold bearing sedimentary formations in the historic Barkerville-Cariboo gold district that extends more than 125 km from Eureka Peak in the south to Wells-Barkerville in the north. Analytical results are comparable to results obtained in early stage exploration elsewhere in the district and particularly at a neighboring property that has reported gold resources of 3.94 million ounces at a grade of 0.581 (g/t) measured and indicated gold in a potentially mineable large tonnage, sediment hosted deposit.
The application of the sonic drilling method in future drilling programs is being reviewed by management on the basis of costs, recoveries and the usefulness of cuttings for sampling and geological interpretation purposes. Other methods under consideration are dual rotary reverse circulation and diamond drilling with a face discharge bit.
A track mounted Boart Longyear sonic drill rig was utilized as a test program to achieve improved recovery from the prospective gold zone. Previous drilling of that zone in 2008 using conventional coring tools gave only partial core recovery and unreliable results (see TIEX news release, January 9, 2009). The sonic drilling technique employs a dual line of drill pipe with a core barrel in the inner pipe. High frequency mechanical oscillations transmit resonant vibrations and rotary power to the drill bit. The sonic vibratory action fluidizes loose and unconsolidated materials and moves the cuttings into the core tube. The outer drill casing is then advanced to the same depth and when the core barrel is removed, the outer pipe holds the drill hole open and ensures that there is no contamination from up-hole material. Hard formations are penetrated using rotary action coupled with vibration. Cuttings are discharged from the core barrel into a polyethylene sleeve that is placed in a wooden tray where it can be opened for examination and sampling. Cuttings comprise small chips, pulverized rock and small rock pieces and the mixture is either powdery or has the consistency of wet concrete. Cored material tends to expand in the presence of water, a condition that makes accurate recovery measurements difficult. Dry portions in most cases return close to 100% of cuttings.
Two drill holes were completed in the same Gold Creek location as the 2008 drill holes GC08 -01, 02 and 03. Drill hole GC 10-01 was drilled due south at -60 degrees to total depth of 37.5 metres (123 feet) and was stopped due to squeezing conditions that prevented advance of the outer casing. The lowermost 5 metres of the hole was drilled with water and showed poor recovery. Total recovery was measured as over 90 %. Drill hole GC 10-02 was drilled vertically from the same site as GC 10-01 to total depth of 102.4 metres (336 feet). The collar was located beside Gold Creek and inflow of surface water into the hole could not be controlled. Most of the cuttings were wet and the volume of cuttings in a sample frequently was greater than the measured length.
Drill hole cuttings were measured, logged and sampled under the direction of the consulting geologist Erik Ostensoe, P.Geo. Sample lengths varied from less than 1.5 metres to more than 3 metres. Each sample comprised approximately 6 kg of cuttings. Where necessary large fragments were sawn with a rock saw equipped with a diamond blade. Sample materials were placed in a standard sample bag, and subsequently stored in a locked facility until delivered by the geologist directly to the ISO-9000:2008 registered and ISO 17025 accredited ALS Chemex analytical laboratory in North Vancouver, B. C. "Blank" samples were inserted at random into the sample stream to ensure the quality of analyses.
Seventy-five drill cuttings samples and three "blank" samples were submitted to the analytical laboratory. Samples were prepared and processed as follows:
- Weighing, drying, crushing to (greater than) 70% -2mm
- Pulverize 1 kg to (greater than) 85% -70 microns
- The sample was analyzed following the ALS Chemex 1000 gram screen
fire assay procedure: duplicate assays on -100 micron fraction,
assay entire oversize fraction. Total gold content is reported.
For quality assurance purposes, the laboratory also performed duplicate analyses of several of the TIEX samples, and analyzed standard samples and their own "blank" samples. TIEX and its geological consultant are satisfied that the ALS Chemex procedures and analyses, including their internal QA/QC, are appropriate and follow current mining industry standard methods.
Erik Ostensoe P.Geo. who is a "Qualified Person" as defined under National Instrument 43-101, supervised the recently completed program of sonic drilling at TIEX's Gold Creek property near Likely, B. C. and believes that this News Release accurately presents and interprets the scientific and technical information relevant to that program. On this project Erik Ostensoe P. Geo reported to John Buckle, P.Geo and P.Geoph and VP Exploration for Tiex Inc.
