Partners KWG Resources (KWG-T) and Spider Resources (SPQ-A) have released the results of their first mini-bulk test hole at the Kyle Lake diamond project in northeastern Ontario.
From the first of 11 holes drilled during the partners’ winter program at Kyle Lake, 851 diamonds were recovered, of which 22 were larger than 0.8 mm in diameter, and 133 were between 0.5 and 0.8 mm. The largest diamond recovered weighed 0.0935 carat, and is described as a clear, fragmented complex crystal.
About 15 tonnes of material were procured from the Kyle Lake kimberlite, which has been interpreted as a multi-phase, layered kimberlite.
The mini-bulk test included sampling to determine the spatial distribution, both horizontal and vertical, of diamonds. Tests conducted by the companies in 1995 suggest that grades of up to 8 carats per tonne over a vertical drill length of 12 metres could be expected.
Definition drilling indicates that the kimberlite extends over 3.2 hectares, from 130 to 450 metres underground, with a slight taper at depth.
In July, KWG and Spider will estimate the diamond value of a small parcel of the Kyle Lake kimberlite.
