ARMSTRONG, BRITISH COLUMBIA - GWR Resources Inc. (TSX Venture: GWQ) is pleased to announce that, following compilation and re-examination of previous work, drilling has resumed on the Aurizon South area within the Company’s Lac La Hache property. Initial focus will be to prove continuity of high grade copper-gold intersected approximately 275 m below surface in hole AZS08-07 (see News Release dated Dec. 9, 2008), which was drilled to test a new deep-IP (induced polarization) anomaly. Additional high-priority targets have been interpreted in other areas. A summary of GWR’s exploration activities since drilling was suspended at the end of 2008, and the rationale behind the current drilling concepts, are provided below.Summary
The Company suspended diamond drilling in December 2008. Work continued on site clean-up and remediation work, data entry, compilation, integration and interpretation. Results of this data review include new exploration targets in at least three areas, requiring detailed drilling to test continuity of high-grade mineralization, grassroots surface work (new, focused bedrock mapping, soil sampling, trenching/sampling), or drill testing of new targets. Work also commenced in preparation for permits for 2009 activities. Reorganization of the project at management and field levels is also underway. Having obtained all permits necessary to resume drilling, one diamond drilling rig was recently mobilized to the Aurizon South area of the Company’s Lac La Hache property and drilling resumed this morning.Data compilation, Integration, and Interpretation
As reported previously, exploration during 2007 and 2008 was conducted at a relatively high level, including new geochemical and geophysical surveys, and a large diamond drilling program was completed in selected areas. Positive drilling results were obtained, particularly in the Aurizon South area where drill hole AZS08-07 tested a newly defined deep-IP anomaly, and intersected high grade copper-gold approximately 275 m below surface (see News Release dated Dec. 9, 2008). Important geological and structural controls on mineralization were identified, but establishment of continuity is hindered by numerous post-mineral, off-setting faults.
In recognition of the high potential of the Aurizon South mineralization, and its significance as a model for reinterpretation of mineralization and geochemical/geophysical anomalies elsewhere on the large property (Aurizon Central, Ann North, “Jack” claims, for examples), the Company suspended drilling in December 2008 to allow thorough re-examination of all recent exploration data and historical results in selected areas. Currently, all drill assays have been received, compiled, and plotted; all drill logs exist as digital (PDF) files with assays embedded; and north-south and east-west sections and level plans (as PDF files) of all recent drilling have been generated. This work was required to maximize the use of the now large amount of data on the property to ensure a well designed, efficient exploration program in 2009, comprising careful follow-up drilling and surface work focused in selected areas to address specific goals.
Integration of all drill core assays and descriptive (geological) core logging into a consistent digital database was ongoing, and has provided the required framework for reinterpretation. Mineralization associated with intense hydrothermal brecciation and associated alteration of the host monzonitic intrusion in the Aurizon Central and South zones has been interpreted to be north to north-easterly plunging, with possible offsets to the west (with depth) across shallow southerly-dipping, ESE-trending young faults. Mineralization in holes lying outside the currently interpreted zones supports this model, as do geological, structural and alteration features now recognized in weakly or unmineralized holes. For example, mineralization was intersected near the bottom of Aurizon Central zone holes AZ08-96 and 101 approximately 200 m north of the mineralization in hole AZS08-07, supporting the interpreted westerly offset of a north to north-easterly plunging zone. Copper mineralization within hydrothermal breccia at the bottom of hole AZ07-20 lies (horizontally) 185 m northeast of the zone in AZS08-07. Hole AZ08-63 was drilled vertically along the eastern side of the current Aurizon Central drill pattern, and cut mineralized, hydrothermally brecciated, hybrid monzonite/volcanic rocks lying below a series of faults. The bottom of the hole grades 0.36 % Cu and 0.66 gpt Au over 11.6 m, including 2.6 m grading 0.8 % Cu and 1.57 gpt Au at the very end of the hole. Again, this mineralization lies northeast of the AZ08-07 zone, by approximately 225 m (horizontally).
The structural complexity associated with post-mineral faulting requires a cautious approach to prove continuity of the AZ08-07 mineralized intersection. The first four holes have been positioned on 25 m centers, to provide testing to the east, north and northeast. Web versions of the related drill plans and sections are currently in preparation and will soon be posted at www.gwrresources.com.
In the historically drilled Ann North area, high grade copper intersections (individual core assays up to 2% Cu) in holes AN00-24 and AN04-36 lie above new, untested deep-IP targets. Where possible extensions of the IP anomaly appear closer to surface, increased soil copper values occur. The combination offers additional 2009 drill targets.Lac La Hache Facility, In-House Analyses
The quality of all exploration activities has benefitted from the secure, integrated office/core logging/core storage facility now located in Lac La Hache. Core relogging was conducted over the last several months, with proper lighting, heat, easy access to racked core and computer support/data entry, and large format colour plotting, all under the same roof.
The company-owned state of the art X-Ray Fluoresence (XRF) spectrometer (InnovX Model X-50) has been used to provide reliable estimates of concentrations of copper and other elements in various materials including drill core, bedrock and soil samples. Crushing capability in the Company’s facility improves both accuracy and reproducibility. Results have been used to guide sampling protocols. For example, soils collected in the fall of 2008 by GWR staff on the Jack claims, were dried, sifted and stored securely for subsequent analyses. Of seventy samples collected, 20 provided sufficiently anomalous in-house XRF results (including 3 sites where XRF copper results were 20 times local background values) to warrant formal 43-101 compliant analyses and these have been recently sent to Ecotech Labs in Kamloops (analyses pending). These overlie an untested deep-IP anomaly located on the Jack claims, within a strong airborne Th/K ratio low, all lying northeast of the AZ08-07 zone. In addition, surface bedrock samples in the area have also returned anomalous XRF copper values, presenting a very positive, new, well-defined exploration target. Reorganization
During 2009, the Company reviewed its operational requirements in the context of current economic trends and property exploration status and potential, and has taken steps to improve the potential for success. In keeping with the Company’s long-standing goal of creating shareholder value through grassroots discovery in British Columbia, changes include (or will include) new directorships, new field geological staff, and improved field, reporting and communication procedures to better direct limited exploration funds towards best possible targets. One such change was the recent appointment of Rob Shives, P.Geo. as VP Exploration and as a director of the Company. Further changes will be announced as appropriate.
The Company maintains a quality assurance/quality control program that conforms to the requirements of National Instrument 43-101. Rob Shives, P.Geo., is the Qualified Person (as defined by NI43-101) who accepts responsibility for the technical content of this news release.About GWR Resources Inc.
