Evolving Gold Corp. (TSXV: EVG) (FSE: EV7) has announced additional assay results from the 2010 core drilling program at its Rattlesnake Hills project in central Wyoming.
Drill hole RSC-135, part of an infill drilling program at the North Stock gold zone, intersected 405.4 meters at 1.31 gpt Au, including 50.3 meters at 5.87 gpt Au, and 7.6 meters at 21.82 gpt Au.
Summary of Results:
- Drill hole RSC-135 intersected 405.4 meters at 1.31 gpt Au (1,330 ft at 0.038 opt Au), including 50.3 meters at 5.87 gpt Au (165 ft at 0.171 opt Au) and also including 7.6 meters at 21.82 gpt Au (25 ft at 0.637 opt Au).
- Drill hole RSC-132 intersected 334.7 meters at 1.12 gpt Au (1,098 ft at 0.033 opt Au), including 93.0 meters at 2.68 gpt Au (305 ft at 0.078 opt Au) and also including 18.3 meters at 5.17 gpt Au (60 ft at 0.151 opt Au).
Near vertical drill holes, RSC-132 and RSC-135 were drilled from a location near the top of North Stock Hill, and were drilled to the south to test the vertical continuity and extent of the central portion of the North Stock gold zone. Both holes intersected continuous gold mineralization beginning at shallow depths and extending to vertical depths in excess of 300 meters. Oxidation in these drill holes persists from the surface to vertical depths of approximately 150 meters and extends deeper along mineralized structures.
"Drill holes RSC-132 and RSC-135 both collared on a new drill pad constructed near the top of North Stock Hill, near the center of the diatreme breccia," comments Quinton Hennigh, President and Chief Geologist for Evolving Gold Corp. "Both holes demonstrate continuity of mineralization to depths of over 300 meters, and it is particularly encouraging to see mineralization starting within a few meters of the surface. We are also particularly pleased to see the depth of oxidation in these drill holes, which persists to depths that include the very high grade interval in drill hole RSC-135."
Infill drilling at North Stock and at Antelope Basin in 2010 was designed to improve delineation of the high grade gold mineralization within the larger volume of more modest grade gold values. The results of this drilling at North Stock have started to define a network of anastomozing, northeast-trending, steeply dipping high grade structures within the core of the North Stock gold zone. To date, drilling indicates a total strike length of this high grade zone of gold veins of approximately 300 meters. The most shallow intersection of the high grade zone is at about 79 meters, and the deepest is at nearly 400 meters below surface. All of the high grade veins appear to be within a corridor approximately 70 meters wide that forms the high grade core to the North Stock gold zone.
"Until recently our drilling was too widely spaced to adequately evaluate the higher grade gold mineralization at North Stock," states Quinton Hennigh. "With the completion of our 2010 drilling program, we now have intersections across most of the North Stock gold zone at 50 meter spacing. As a result, we are starting to see that some of the high grade intersections in the early drill holes appear to tie together with the more recent intersections. We therefore believe that we will be able to do a much better job of modeling these high grade structures once we have all the assay results from our 2010 program."
The Company completed a total of 63 core holes in 2010, for a total of approximately 25,600 meters (84,000 ft) of drilling. Assays are still pending for 21 drill holes. Of the remaining holes, fourteen are infill and step-out drill holes at North Stock, and five are infill and step-out drill holes at Antelope Basin. One hole tested a new mineralized zone between North Stock and Antelope Basin, which was discovered earlier in 2010, and one hole tested the deep porphyry target.
Mineralized Intervals, North Stock Zone
Drill holes RSC-133 and RSC-134 targeted deeper portions of the west end of the North Stock gold zone. RSC-133 was drilled in a northerly direction from south of the southern contact of the diatreme. RSC-134 was drilled in a southwesterly direction across the core of the diatreme from the north side of North Stock Hill.
