ASHBURTON VENTURES INC. (TSX VENTURE:ABR)(FRANKFURT:ARB) announces further results from samples taken along the Upper Vein area of its Deep Creek Project located 112 kilometres north of Elko, Nevada.
The latest field program produced, among other very notable results, a channel sample over one meter in width along the furthest southern end of the Upper Vein assaying at 47.9 g/t gold which appears to penetrate the softer clastic sedimentary units of the Paleozoic Schoonover Formation.
This new set of results has extended the Upper Vein southward for a total length of approximately 640 meters. The data has also revealed that the Upper Vein is actually a network of veins occurring dominantly in the Precambrian McCoy Group metasediments (see news release dated October 14, 2010), but also extending southward into Paleozoic sedimentary rocks identified as the Schoonover Formation.
In addition to the Upper Vein sampling, a float sample of vein material was also taken from above the Upper Vein area which assayed at 28.90 g/t gold. This result is particularly encouraging, as it indicates that additional gold-bearing veins must occur above the known trace of the Upper Vein.
"We are very excited with Ashburton's latest set of results at its Deep Creek project in Nevada. The fact that the Upper Vein is now over 640 meters in length and up to one meter in width, and that the country rock surrounding it is also carrying gold values, is extremely encouraging," states Mike England, Company president. "In addition, float samples of vein material with high gold values have been confirmed above the Upper Vein, meaning an additional gold-bearing zone, or zones, are yet to be discovered."
Based on the encouraging results of the Upper Vein area, a program of further sampling, detailed structural mapping, and high resolution geophysics is planned for the coming months, to aid in selecting targets for drilling in early 2011.
The latest sampling program focused on obtaining assays northward for the Upper Vein, and extending the Upper Vein southward through prospecting. The southward prospecting identified the Upper Vein in poorly consolidated sedimentary rock interpreted to be the Schoonover Formation. Two Upper Vein samples in the Schoonover Formation have continuous widths of 1.0 and 1.2 meters, and gold contents of 47.9 and 42.5 g/t Au, respectively.
Sampling the Upper Vein northward proved to be difficult as the vein is poorly exposed due to loose surface cover, but where possible, channel widths of 0.15 meter were chiselled from the rock until sample weights exceeding one kilogram were obtained. Discontinuous vein widths mostly less than one meter were assayed, with values ranging from near detection limits up to 0.94 g/t Au.
Company geologists also chiseled composite bedrock channel samples northward in the Upper Vein, from areas roughly 0.45-0.91 meters in length and 0.1-0.2 meters in width along lines spaced approximately 20 meters apart over a total distance of 80 meters. Visible gold was not observed during collection, but assays up to 2.30 g/t Au were obtained.
Country rock samples were also collected along the southward extension of the Upper Vein, including one sample in highly variable lithologies of the Schoonover Formation that are capped by Tertiary volcanics. A composite channel sample of these variable lithologies returned a 0.1 g/t Au result, which suggests that enhanced gold values may extend beneath the volcanics.
Samples are prepared and analyzed for gold by ALS Chemex Laboratories, North Vancouver, British Columbia, using the fire assay protocols Au-AA24, Au-AA25, and Au-GRA22 that provide detection ranges of 0.005-10, 0.01-100 and 0.05-1000 ppm gold, respectively.
In sampling the Upper Vein area, care has been undertaken to collect unbiased representative samples, but samples containing coarse gold can have an inherent nugget effect. For the most recent sampling in the Upper Vein area, samples in which visible gold was noted or which appeared to have the potential for coarse gold to be present, were subjected to the ALS Chemex protocol Au-SCR21. This protocol assays the pulp and coarse fraction at a 100 micron square mesh cutpoint to determine the total gold content of the sample. This assay approach is considered industry best practice for samples suspected of having a coarse gold component, and the reported results are the total gold contents using this protocol.
