DIAMOND PAGE — Trade Winds finds macrodiamonds at Drybones Bay

The processing of 1,874 kg of core, collected from drilling on the Drybones Bay kimberlite pipe, has yielded 25 macrodiamonds.

Trade Winds Resources (TDN-V) holds the right to an 80% interest in the property, 50 km southeast of Yellowknife, N.W.T.

Eight of the macros measure between 0.5 and 0.75 mm, seven are between 0.75 and 1.75 mm, and 10 of the stones fall between 1.75 and 3 mm.

In all, a total of 42 macros have been recovered from 2,512 kg of sampled kimberlite for a preliminary grade estimate of 16.2 carats per 100 tonnes, or 0.162 carat per tonne.

The Drybones Bay kimberlite is an oval-shaped pipe, with a surface dimension measuring 900 by 400 metres. Drilling has identified several phases within the pipe. The grade of the richest central facies is estimated at 23.7 carats per 100 tonnes, or 0.237 carat per tonne.

Stones within the upper crater facies are commonly fragments of larger diamonds, while a significant portion of the diamonds from the diatreme (central) and hypabyssal facies are clear, white, intact octahedra. The largest diamond recovered measures 2.5 mm and is described as a clear, slightly pale-brown, twinned octahedron.

A summer program will consist of further delineation drilling on the different phases of the pipe.
