GWR Resources extends Gold-rich Aurizon Central Zone, improves exploration
targeting
ARMSTRONG, BC,
Hole AZ09-102 was positioned along the north-eastern corner of the Aurizon Central Zone to confirm the eastern boundary as projected from holes drilled in 2008. Earlier interpretation suggested the hole would effectively define the eastern limit of the Zone, but the intensity of alteration (chlorite, hematite, calcite veining) and fracturing encountered throughout the hole and especially towards the bottom (368 meters below collar) indicates extension to the east is possible at depth. Low copper values with weak gold enrichment ((greater than) 0.1 gpt Au) were intersected at the top (0.1 gpt Au over 26 m with 0.33 gpt Au over 3 m from 23-26 m) and further down-hole from 80-107 m. Spotty native copper was noted near the top. Hydrothermal breccia was not observed, but zones with increased alteration occurring towards the bottom have returned elevated gold and copper values (0.16 gpt Au over 33 m from 275 to 308 m). These results prompted additional sampling to the bottom of the hole, which has extended the low-grade gold zone an additional 33 m down-hole resulting in 66 m at 0.16 gpt from 275 to 341 m. This includes a narrow higher-grade zone (0.32 gpt Au over 9 m from 308 - 317 m).
Hole AZ09-103 was drilled on the north side of an east-west oriented (110 degrees) fault lying north of the core of the ACZ. The goal was to extend known mineralization towards the north and to determine possible offset direction/distance across the fault. The hole intersected mineralized orange polylithic tuff with traces of native copper, a 75 m (down-hole) wide zone of variably mineralized hydrothermal breccia (refer to table of assays, below), then unmineralized grey monzonite. One faulted interval contains 7.49 gpt Au over 2 m. The apparent displacement of hydrothermal breccia and mineralized zones between drill sections located at 8120N and 8160N is approximately 100 m. This has confirmed our previous interpretation whereby east-west faults appear to down-drop the mineralization to the north, providing continued encouragement that additional mineralization lies untested in that direction. A westerly component of movement is also apparent. This area will be a focus for additional drilling in our 2010 exploration Program.

The Lac La Hache exploration team has been very active during the current, non-drilling phase. All re-logged
GWR has commenced a program to rigorously evaluate the large quantity of multi-element values resulting from Inductively Coupled Plasma (ICP) analyses and Cu, Au, Ag assays of recent and many historical drill cores.
The database is estimated to contain over 800,000 values. Software has been developed in-house to produce ten-meter-averaged plan maps for all elements in all drill holes, supporting local zone and property-scale correlation with geology, geophysics, structures, mineralization and alteration patterns, again leading to improved vectoring. Comparison of the multi-element core data with the new soil MMI 8-element data, in-house XRF analyses of drill cores and magnetic susceptibility measurements will also be completed. This information will significantly improve understanding of the relationships between gold, copper, silver, other potentially economic minerals that have not been rigorously evaluated to date, and potential pathfinder elements which may serve as vectors towards improved grades, perhaps at depth below several of the historical, shallow-drilled zones.
The work conducted at Lac La Hache in 2009 has provided new encouragement in several areas. Although far less drilling was conducted during 2 campaigns in 2009 than in previous programs in 2007 and 2008, targets were carefully selected with specific goals, and as described in several recent news releases, results were largely successful. (see all news releases and additional information at www.gwrresources.com) The narrow but very high-grade gold-rich Aurizon South Zone was extended to the north and south and remains open. Aurizon Central drilling successfully extended the zone to the north, where it also remains open. Preliminary reserves have been calculated for Aurizon Central and results indicate grades and tonnage comparable to zones currently being exploited at Mount Polley. GWR has obtained a combined copper equivalent grade/tonnage figure, but is waiting for confirmation of the separate, contained gold and copper figures before releasing this information. The company expects to have this information by the end of January, 2010.
The Company completed a 1300 sample MMI soil sampling program in the fall which has already proven extremely encouraging, generating new discoveries of copper and gold within potassically altered monzonite, including structurally controlled copper exceeding 11% Cu and 0.6 gpt gold. Using our in-house XRF analyses, the MMI results, and laboratory geochemical analyses of the many drill cores, the exploration team has shown that non-gold-bearing pyrite yields low cobalt, and gold-rich pyrite (assays in the multigram/tonne Au range) is associated with high cobalt. The MMI approach supports mapping of the cobalt distribution in soils, and IP surveys allow mapping of pyrite-rich zones in the bedrock, both methods offering detection to considerable depths. Combined interpretation of these results will yield new targets to be followed-up with systematic trenching, sampling and assaying early in the spring 2010 program. A much larger, property-wide MMI program designed to cover the entire property will be completed as soon an environmental conditions allow.
Our goal is to use the power of improved geochemical analyses to re-evaluate the soil metal anomalies (not just Cu and Au values) in combination with new bedrock sampling (in new anomalous areas) and a revised exploration model evolving from consistent core relogging of all holes drilled on the property to date, to prove that the large alteration system has bulk-mineable potential. The presence of gold-rich zones within the system provides some additional encouragement.
The 2010 Drilling Program will focus on new targets indicated by the new data and on testing several areas where mineralization near surface discovered from relatively shallow historical drilling supports potential for deeper ores below. The recent and exciting new deep discoveries made within the Quesnel Trough at several properties, below known mineralization, provides a model for the Lac La Hache property, which has the advantage of easy access and very good infrastructure.
