Shares in Hudson Resources (HUD-V) jumped as much as 31.5% to 48 in afternoon Venture Exchange trading after the diamond explorer said it had recovered from its Sarfartoq licence the largest diamond ever found in Greenland.
The stone measures 2.6 by 2.3 by 2.26 mm, and is more than twice as large as the company’s previous record find.
The colourless, included octahedron was liberated from a 158.7-kg sample of kimberlite float collected 500 metres south of the Garnet Lake discovery area. In all, 226 diamonds were recovered, including 13 macrodiamonds exceeding 0.5 mm in all three dimensions.
The haul also included a 1.4-by-1.16-by-0.86-mm clear, pink rough stone and a clear, amber broken fragment measuring 1.46 by 1.12 by 0.46 mm.
Says Hudson’s exploration manager Mark Hutchison: “The quality of the diamonds recovered is of particular interest to us. The recovered stones typically have good colour and shape and pink diamonds are always of interest to the gem industry.”
Hudson also says that diamondiferous samples from either side of Garnet Lake have extended the potential north-south strike of the body to more than 900 metres. The company also says that strike length could grow based on kimberlite indicator mineral chemistry found in tills north and south of the Lake.
Sample 25-D2, collected from the company’s final hole of 2005 collared 400 metres north of Garnet Lake yielded 4 microdiamonds from just 6.6 kg of kimberlite. The hole encountered 1.9 metres of kimberlite at a depth of around 15 metres.
Finally, kimberlite from drill hole 05DS23 and surface sample MHGB21 located another 500 metres to the northwest yielded just 4 micros from what is now believed to be a “non-diamondiferous en-echelon dike” frequently encountered by drilling.
Meanwhile, two samples (MHGB 15 and 16), totalling 187 kg, collected in a newly identified area some 12 km to the northeast of Garnet Lake returned a total of 73 diamonds, including 3 stones which exceed a 0.6-mm square mesh screen classification. Sample MHGB15 contained a broken stone exceeding 2 mm in one dimension.
The samples were derived from two areas separated by 300 metres in a gully. Hudson says it is not yet clear whether they represent the same kimberlite body. The company says the samples exhibit the same physical characteristics as those at Garnet Lake.
Hudson says the coarse diamond-size distribution in the samples is very interesting, and plans a geophysical survey over the area.
