TORONTO, ONTARIO--(Marketwire - May 19, 2009) - COGITORE Resources Inc. (the "Company") (TSX VENTURE:WOO) is pleased to report a thick high grade volcanogenic massive sulphide (VMS) intercept at its Scott Lake project, located 20 kilometres west of the rail and road hub of Chibougamau, PQ (Figure 1: http://media3.marketwire.com/docs/Fi... ). The last hole of the program, SC-40, cut a 27.4 metre interval of massive sulphides made up of a 9.3 metre interval of 2.5% copper, 7.9% zinc, 0.8g/t gold and 109.1g/t silver, which immediately follows an 8.7 metre interval of 0.2% copper, 24.7% zinc and 28.9g/t silver. The two intercepts are part of a 27.4 metre consecutive interval of massive sulphides with a weighted average of 1.2% copper, 13.4% zinc, 0.3 g/t gold and 58.6 g/t silver related to the West Lens. The West Lens is one of five known lenses to occur on the Company's wholly owned Scott Lake Property. A less well mineralized intercept of 5.5 metres of 2.6% zinc (including 5.2% zinc, 0.8g/t gold over 0.8 metres) located higher in SC-40 (408.0m to 413.5m) also provides confirmation that the Zinc Zone intersected in Hole SC-34 is a third 'stacked' mineralized horizon. The VMS intercept in hole SC-40 starts at a vertical depth of 430 metres, just a few metres higher than the West Lens intercept in SC-34 but located 30 metres north of SC-34 (Figure 2: http://media3.marketwire.com/docs/Fi... ). Internal layering in the massive sulphides is not well developed and core angles cannot be used to estimate true width. However, from the sketch on Figure 2 (http://media3.marketwire.com/docs/Fi... ) it can be seen that the core length is very close to true width. Weighted averages of assays from SC-40 are tabled below: DDH SC-40 (weighted averages)

"We were somewhat surprised by hole SC-40 but certainly pleased with both the grades and the thickness" commented Dr. Gerald Riverin, the Company's President and CEO. "The intercepts in holes SC-40 and SC-34 indicate a horizontal, rather than vertical orientation as was expected initially. This recent interpretation is consistent with core angle observations made in SC-34 and opens up a significant area of strike length in both plan and section. Overall, the 2008-2009 drilling program at Scott Lake has been very successful as thick sections of copper enriched massive and stringer sulphides were intersected by drill holes SC-40, SC-34, and SC-30 in an area that had previously been thought to host only relatively thin zinc-rich lenses." While drilling in most areas of the Scott Lake Property is possible for 12 months of the year, before beginning its next phase of drilling at Scott Lake, the Company's geologists need to: 1) Examine all the implications of flatter than expected dips in the SC-34 & SC-40 area. 2) Re-examine interpretations based on old drill holes. Drill hole SL-91-77 seemingly cuts off the West Lens to the north (Figure 2: http://media3.marketwire.com/docs/Fi... ). However, experience has shown that when old drill holes have been re-entered by the Company and re-surveyed for down-hole deviation with more modern equipment, the plotted locations of the old holes commonly change significantly, which could change the interpretation of the size and shape of the West Lens. 3) Examine new geophysical data on the area. A geophysical firm, working on its own initiative, modelled the public SC-34 drill hole results with prior airborne (MegaTEM) geophysical survey results which appeared 'flat' or non-responsive based on public data. In a technical paper given at an international meeting in China last April the firm's geophysicists claimed to be able to detect or 'see' the mineralization in SC-34 and, most interestingly, the paper also shows similar un-drilled MegaTEM anomalies located respectively 600 metres northwest and 350 metres south of the West Lens geophysical response. Some ground geophysical follow-up and further modelling is therefore likely, as well as further deviation testing of old drill holes around the West Lens. When drilling does resume there will be two objectives: 1. To drill the West Lens off on 25-30+ metre centres by wedging off existing drill holes, and where necessary drilling new holes. This will allow for a calculation of NI 43-101 compliant resources. 2. Test the recently recognized geophysical targets to the Northwest and South. Work is carried out by the personnel of Cogitore Resources Inc., under the supervision of Gerald Riverin, PhD, P.Geo. He is a qualified person (as defined by National Instrument 43-101) and has more than 31 years of experience in mineral exploration. Drill core from holes SC-37 to 40 inclusive were logged and marked up for assay at the Company's secure facility in Chibougamau, Quebec. Drill core for assay was split in half. Half of the core was shipped in sample bags to the ALS Chemex laboratory in Val d'Or, PQ for specific gravity measurement and sample preparation. Pulps were flown to Vancouver, B.C. for analysis with appropriate standards, duplicates and replicates used for quality control purposes. The other half of the core is retained for future reference. Cogitore explores for VMS-type deposits in areas where such deposits have been found and mined before. Exploring in such areas is preferred because of existing infrastructure, knowledgeable local workforces and broad public support for mining. Collectively, these are major competitive advantages for logistics and economics. |
