A 48-kg sample of diatreme breccia from the Kyle project in northern Ontario has been found to contain 26 diamonds.
Included in the haul are 6 macrodiamonds (measuring at least 0.5 mm in one dimension) and 20 microdiamonds (less than 0.5 mm). The largest stone falls in the range of 0.85-1.18 mm; nearly half the remaining stones measure between 0.212 and 0.3 mm. About 30% of the diamonds are clear, white, gem-quality stones; half are white with inclusions.
Diamond results for small amounts of attrition mill oversize and heavy mineral concentrates are pending.
The 48-kg sample was derived from a 33.5-metre section (beginning at a depth of 138.6 metres) of core (3 cm in diameter) from a vertical hole collared on the centre of a magnetic anomaly, the source of which is estimated to be at least 180 metres in diameter.
In addition to the diamonds, the sample yielded eight diamond-inclusion G10 pyrope garnets, more than 100 diamond-inclusion chromite grains, and 155 titanium chromites.
Metalex will use a large-diameter drill to delineate targets and collect a 300-kg sample of the kimberlite for diamond recovery.
The kimberlitic rocks were discovered during triaxial aeromagnetic gradiometer surveys over an area measuring 15,000 sq. km. Additional targets have been identified and secured by staking.
Charles Fipke’s private company, Kel-Ex Development, manages Metalex’s exploration projects; Fipke is also chairman of Metalex, and Metalex President Peter Gregory is also an employee of Kel-Ex.
Metalex finished 23, or 34%, higher at 90 on the TSX Venture Exchange at presstime. Arctic Star ended 3 better at 25.
