GWR Resources Inc. (TSX Venture: GWQ) announced resumption of drilling on the Aurizon South Supergold Zone, and completion of bedrock sampling over the Spout Lake Skarn Zones, within the large Lac La Hache Project located in central British Columbia, Canada.
Aurizon South Supergold Zone
As previously announced (see News Releases for May 27, July 15, and August 26, 2010), several holes drilled within the Aurizon South Zone define a northeast trending near-vertical structure characterized by hydrothermal breccia containing multi-gram gold, copper, silver. The trend is open and extends from surface to more than 600 m depth, with strike length ranging from 170 (drilled) to 630 meters or more (interpreted). Drilling earlier this year is highlighted by results from AZS10-21 which extended the zone vertically to a depth of more than 600 m (1.36 gpt Au, 0.31 % Cu over 137 m from 477 to 614 m, including two 10 m intervals exceeding 5 gpt Au and another 8 m interval exceeding 3.6 gpt Au). Mineralization occurs as disseminated, fracture-filling and massive chalcopyrite, fine grained bornite, gold-cobalt-bearing pyrite, and magnetite in hairline-to-cm thick stringers. Visible native gold has been observed in quartz-albite (AZS09-16). Various maps, sections and diagrams depicting the structure, hole locations and related mineralized trends are provided at www.gwrresources.com under the heading "Lac La Hache Project".
New results from our 2010 Mobile Metal Ion© (MMI) soil sampling (now completed over the entire ~50 km2 property) define a strong gold anomaly centered over the Aurizon Central porphyry gold-copper zone, extending along a well-defined 200 degree trend across Aurizon South Supergold Zone and continuing for over 2000 meters. A similar, parallel MMI gold trend occurs 550 meters to the west. These represent the largest and highest amplitude MMI Au anomalies on the entire property (see images on website).
GWR is excited about the economic potential of the Aurizon South Supergold Zone, and its genetic relationship to the adjacent Aurizon Central porphyry-Au-Cu Zone to the north. We have received a 3-year exploration permit to support ongoing work here. Our drilling will continue to systematically delineate, in-fill and extend known intersections, to support a NI43-101 compliant resource estimate.
Spout Lake Magnetite-Copper-Gold-Silver Skarn Zones
On September 1, 2010, GWR reported discovery of new mineralization within the Spout Lake Skarn Zones, resulting from bedrock sampling within extremely high amplitude (up to 81,000 nT) magnetic total field anomalies defined by new high resolution ground magnetometer surveys (see images on website).
Assays of several bedrock grab samples have returned values up to 0.53 gpt Au, 3.05% Cu, 19.2 gpt Ag and 66 % Fe (equivalent to 90 % magnetite if all Fe assumed to be in magnetite). Results of independent sampling have confirmed these results and indicate favourable metallurgy. Additional bedrock sampling has since been completed and continues to extend known mineralization beyond previously defined surface limits. Samples collected in all of the high magnetic anomalies (> 65,000 nT) have produced massive magnetite with abundant disseminated chalcopyrite, strong malachite and azurite. Results from an additional 19 samples are expected soon and will be reported when received.
Our technical team has just completed re-logging of historical drilling within the North and South Skarn Zones and has compiled all available geological, geophysical, geochemical and assay data. We are pleased to report that the historical (1993, non-43-101 compliant) resource for the North Zone (595,113 tonnes grading 50.5% magnetite, 1.79% Cu, 0.12 gpt Au) included drilling to only approximately 200 meters and subsequent drilling in 2005 intersected the zone another 100m deeper, cutting a 15 m interval containing massive magnetite (>60% locally) and copper assays up to 1.8% Cu, 0.45 gpt Au. This extends the zone significantly, to 300 m below surface, and it remains open to depth. In addition, the new ground magnetometer survey has extended the North Zone along strike to the southeast another 70 m beyond the historical resource drilling, and it remains open in that direction. Currently, the North Zone is defined by lenses, pods and stratiform bands of massive magnetite-copper-gold-silver mineralization over a 400 m strike, 300 m vertical depth and ranging from a few meters to tens of meters thick (average appears to be 10 m).
The South Zone was not included in the historical resource calculations due to insufficient drilling density and apparent discontinuity. However, the new magnetometer data, bedrock sampling and re-logging results provide strong evidence that the South Zone is oriented sub-horizontally, dipping to the east or southeast at 15 - 20 degrees, is larger and thicker than previously thought, comprising more than a dozen magnetic highs within relatively moderate to low magnetic values. Surprisingly, the highest MMI soil copper values are associated with the lower magnetic total field values, suggesting significant copper (gold-silver?) may also occur in non-magnetite skarn between the magnetic highs. This idea is supported by high copper values intersected in three historical holes drilled into magnetic lows. The South Zone magnetic anomalies lie within an area measuring 250 m east-west by 350 m north-south. Historical drilling indicates an average thickness of 25 m in a near-surface zone, with a sub-parallel lower zone measuring 12 m thick where intersected.
Our fall/winter drilling program within the Spout Lake Skarn Zones will test the lateral and vertical extent of the strongest magnetic anomalies and intervening areas in the South, North and possibly Southeast Zones. This work will be conducted in a manner which supports NI43-101 compliant resource calculations.
