ARMSTRONG, BC, May 20 /CNW/ - 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.
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
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.
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.
