Vancouver – Initial processing of a portion of Hudson Resources‘ (HUD-V, HUDRF-O) 50-tonne mini-bulk sample from its Garnet Lake kimberlite dike in western Greenland has returned 350 diamonds including seven “commercial sized” stones.
The 350-kg representative sub-sample from kimberlite collected last September was processed by caustic fusion to test its diamond content. The grade correlates well with Hudson’s previous sampling of the dike.
“These results are significant because they represent a cross section of the larger 50 tonne sample which is being processed by dense media separation (DMS),” stated Hudson president James Tuer.
Hudson categorizes its “commercial sized” stones as those large enough to be caught by a plus-850 micron square mesh sieve. The three largest diamonds were an off-white 2.59-by-2.19-by-0.72-mm transparent macle, an off-white 1.94-by-1.82-by-1.45-mm translucent fragment with crystal faces and a white 1.37-by-1.11-by-0.80-mm translucent dodecahedron.
In analyzing 12 of the larger stones, processing lab SGS Mineral Services described nine as white and three as off-white.
Hudson expects processing of its 50-tonne mini-bulk sample to be completed in February. The kimberlite is put through a dual stage crushing and concentrating process to maximize recovery. First stage crushing is to minus 6 mm then into a DMS circuit with concentration by X-ray fluorescence and grease table. Stage two will see the material re-crushed to minus 6 mm size by a high pressure grinding roll and back into the DMS with the heavy concentrate run through X-ray sorting and over a grease table prior to final diamond picking.
Shares of Hudson rallied more than 47% on the diamond haul news, closing up 45 at $1.40 apiece on volume of over 2.2 million. The company posts a $30-million market capitalization given its 21.6 million shares outstanding and has a 52-week trading range of 53-to-$2.10.
