Coupes of champagne or banana? <g> "Kennecott's 1995 drill program completed nine holes on kimberlite #29/30, which drilling and geophysical surveys indicated was one large kimberlite with a minimum length of 1300 m and width of 460 m. Kimberlite #29/30 is approximately 18 m thick in holes drilled closest to the edge and increases to more than 100 m thick towards the center. It has an inferred mass of >63.5 million t. A 1345 kg sample of drill core from the nine holes was treated with caustic fusion to recover 181 diamonds of which 32 were macrodiamonds (>0.5 mm) and 149 were microdiamonds. No diamonds greater than 1.2 mm in size were recovered and 152 or 84 percent were clear and white. DDH 95-1, located in the northwest sector of kimberlite #29/30, was the best hole that year, in which 60 diamonds, including 10 macrodiamonds, were recovered from 132 kg of sample. Kennecott Canada Inc. completed an airborne TEM survey in the first part of 1996. Ground magnetic and resistivity surveys plus a gravity profile were carried out on the Torch River property and an 11 hole definition drill program tested kimberlite #28. The surface expression of this "banana" shaped glacially eroded kimberlite is a valley, trending northerly at its north end and northeasterly to the south. The shallowest depth from surface to kimberlite is 102 m. The unbedded kimberlite has a maximum thickness of around 140 m, is shaped like a very flat 'v' in long section and a cone in cross-section. The top is dome shaped; the sides dip outward at 45ø. It is postulated that the kimberlite represents a "spatter cone" in which variations in the level of activity have given visible variations in grain size defined by gradational changes over a few metres rather than distinct bedding."
