Results of the summer sampling program on Superior Diamonds' projects in Northern Ontario have confirmed that several of the areas investigated are in close proximity to kimberlites. This interpretation is based on sampling of glacial material including basal till and eskers down ice from 32 airborne targets delineated using proprietary airborne magnetics. Indicator minerals recovered include pyrope garnet, eclogite garnet, picroilmenite, chrome diopside and chromite. Studies of mineral grains, both visually and by electron probe methods, have conclusively shown that several kimberlite indicator mineral trains are near the source. Ground magnetic surveys were also completed on several airborne targets and confirmed the circular magnetic anomalies. The summer program involved collection of over 500 samples of which results have been received from 200. Several samples of esker material contained more than 40 kimberlite indicator minerals within a target area containing a cluster of circular airborne magnetic features. This cluster of airborne features is located on a structural trend known to host diamondiferous kimberlites in Northern Ontario. To better define targets for drilling, the company is planning to fly a 13,500-line-kilometre high-sense magnetic survey at 150-metre line spacing. The survey is planned to commence in late October and the data collected will be used in conjunction with results from the sampling program to prioritize drill targets. Samples of till, esker material and modern alluvium are being processed at the laboratories of Overburden Drilling Management Ltd. located in Nepean, Ont. Electron microprobe studies on indicator grains are carried out at the Ontario Geological Survey in Sudbury, Ont. The sampling program is under the direction of Dr. Tom Morris. Superior Diamonds is exploring a large area of Northern Ontario using proprietary magnetic data to focus indicator mineral sampling programs. Superior Diamonds is owned 58 per cent by Aurora Platinum.
