Promising Diamond Exploration in West Greenland
Intex Resources holds three exclusive licenses covering over 2 000 km2 in the two main kimberlite regions in Greenland. In the Maniitsoq district Intex holds exclusive exploration licenses of 1 943 km2 essentially covering the entire Maniitsoq Kimberlite Province of West Greenland. A second exploration license of 321 km2 was granted Intex in a little-explored area in the Sarfartoq region, near Søndre Strømfjord/ Kangerlussuaq International Airport in West Greenland.
The first pass exploration campaign carried out in 2006 was encouraging and resulted in the discovery of several new kimberlite dykes and an exceptional sampling program which returned diamonds from 18 of the 20 50-kg samples collected. Of the 67 micro diamonds recovered were 31 stones reported as intact and 36 as fragmented, i.e. pieces of larger stones.
The exploration program in 2007 added numerous new kimberlite dykes and 73 samples totaling approx. 2.3 tonnes were sampled for analysis of diamond content. A particularly encouraging result from this campaign was obtained from two kimberlite dykes that yielded 80 and 24 diamonds respectively, from two 25 kg samples. The 80-diamond sample is the highest number of diamonds per kilogram of sample recorded in the Maniitsoq region kimberlite province and is well above the industry’s rule-of-thumb threshold of 1 microdiamond per kg sample. The largest diamond recovered measures 1.05 × 0.80 × 0.31 mm. It is described as a white and transparent fragment without recognizable crystal faces. The geological setting of these particular samples displays some characteristics known from explosive kimberlite systems and bears some resemblance to pipe structures, which are the classical sources for diamond mining elsewhere and represent much bigger tonnage potential than dykes.
The 2008 season focused on mapping the area surrounding the two very rich diamond finds from last year and to collect additional samples for analysis and characterisation of the associated breccia rocks. In the ongoing process of investigating known KIM (Kimberlite Indicator Mineral) localities throughout the Maniitsoq region, another dyke system was located with 4 parallel kimberlite dykes. The dykes are up to 1.2 meters wide and can be followed up to 4 km’s along strike. Seven 25 kg samples were collected for diamond testing.
It now appears that four distinct dyke swarms have been defined in the Maniitsoq region, where the largest dyke swarm is nearly 30 km long – one of the largest kimberlite dyke systems reported. Each dyke swarm hosts several segments with 2-2.5 m width over several hundred meters of strike length. The mapping has shown that nearly all kimberlites occur in a 60×25 km ENE-trending corridor and the diamondiferous dykes occur in three sub-parallel lineaments striking 80° implying that the kimberlites are related to major transcrustal fractures.
In the Sarfartoq region field activities have been carried out for two field seasons and last year a till sampling program was completed with collection of 94 till samples totalling approximately 1 tonne. The samples were collected for Kimberlite Indicator Mineral (KIM) extraction and analysis and results outlined several areas with diamond favourable KIM’s. Prospecting in these areas led to the finding of new kimberlite boulder tracks in areas with known diamondiferous kimberlite dykes and samples were collected for diamond testing.
All samples from this summer’s field campaign have been shipped to Canada for analysis. 21 samples are being shipped to SCR (Saskatchewan Research Council) for diamond testing but return time for results are not yet known. In addition, 38 samples are shipped for KIM extraction and analysis as a continuing step towards a geochemical characterisation of the in situ kimberlites belonging to the two main kimberlite provinces in Greenland.
