New Blue Ribbon to commence Calling Lake airborne program New Blue Ribbon Resources Ltd NBL Shares issued 7,994,812 May 18 close $0.15 Wed 19 May 99 News Release Mr. Larry Kryska reports New Blue Ribbon Resources it has entered into an agreement with Terraquest Ltd. to complete a high-resolution aeromagnetic survey of its Pelican block near Calling Lake, Alta. The survey is expected to commence within the next week. The company intends to follow up high priority aeromagnetic targets with an efficient and cost-effective ground program, which will include a combination of ground geophysical surveys and diamond indicator sampling. The Pelican block encompasses approximately 450,000 acres within four contiguous properties, Chris, Northslope, Pelican Mountains and Sandy Lake. The properties are along the southern, central and northern slope of the Pelican Mountains, which form part of a major continental drainage divide and may in turn reflect thickened continental crust. Drift thickness within the area of the Pelican Mountains varies from bedrock exposure to a few tens of metres. The properties are less than 40 kilometres north of the Snowbird tectonic zone and less than 80 kilometres south of the axial trace of the Peace River Arch. Regional scale features such as the Peace River Arch and Snowbird tectonic zone are features likely to preserve mantle roots and provide suitable conduits for kimberlite emplacement. The PRA and associated zones of structural weakness may have played an important role in the emplacement of the Mountain Lake, Buffalo Head and Legend kimberlites; while zones of structural weakness associated with the Snowbird tectonic zone may provide suitable conduits for the emplacement of kimberlite. The diamondiferous Jack lamproite, and several other diatremes are situated along the southwestern extension of the Snowbird tectonic zone, near the Alberta-B.C. border. Prior exploration of the Pelican block included reconnaissance-style steam sediment and till indicator sampling. During 1998 the company identified an anomalous population of diamond indicator minerals, including G9, G10 (gurney) garnets and high Cr2O3 chrome diopsides. Of particular interest are sample sites 10958 and 10859. Sample 10859 collected from Calling Creek, north of Calling Lake, is of particular interest, as more than 75 per cent of its drainage originates from within the eastern portion of the Pelican Mountains block. This sample contained four G9 pyropes, a G10 (gurney) pyrope, and a high Cr2O3 chrome diopside. Based upon scatter plots of CaO versus Cr2O3 (2 per cent Cr2O3 and 20 per cent CaO) the chrome diopside plots within the diamond inclusion field. Sample 10859 was collected from a small upland drainage within the central parts of the property. This sample produced five G9 pyropes and a uvarovite garnet. Uvarovite garnets are high Cr-Ca garnets which may have an ultramafic source, and are considered a positive indicator based upon their occurrence with other DIMs. While many of these recovered minerals are indicative of kimberlitic source rocks, the G10 (gurney) garnet and diamond stability field chrome diopsides are a diagnostic feature of diamondiferous kimberlite. Immediately south of and contiguous with the Pelican block, Buffalo Diamonds Ltd. has reported the discovery of several sites with highly anomalous concentrations of DIMs from basal till samples. Till is glacially transported material. Within the immediate vicinity of the Pelican block regional indications are for north to south or northwest to southeast glacial advances, hence from the general direction of the company's Pelican block toward Buffalo Diamonds Ltd.'s Calling Lake prospect. Select sites reportedly include one with over 100 DIMs, another with a pale yellow macrodiamond, and others with exceptional quality, diamond stability field G10 garnets. The quantities and mineral chemistry of the DIMs recovered by Buffalo Diamonds Ltd. are the best indicators of potentially diamondiferous kimberlite seen in Alberta to date. The volume and variety (such as the presence of olivine) of the DIMs recovered strongly suggest a local source. Three high-priority target areas have been delineated near Calling Lake. Two of these high-priority targets lie immediately down ice of New Blue Ribbon's Pelican block. The company is highly encouraged by the results obtained to date on the Pelican Mountain area. The company views this as an encouraging indication of a local diamondiferous kimberlitic source. (c) Copyright 1999 Canjex Publishing Ltd. canada-stockwatch.com
