Karelian encouraged by Riihivaara results

By BFN News | 08:37 AM | Monday 01 December, 2014


Karelian Diamond Resources says sample material from its Riihivaara target in the Kuhmo region of Finland has been confirmed as being derived from the diamond stability field of the Earth's mantle and that eclogitic grains are also present in the sample. Karelian says the presence of eclogite mantle materials is significant, as these tend to be associated with richer diamond grades. The sample material was sent for analysis by Scanning Electron Microscopy at the Geological Survey of Finland (GTK) laboratory in Helsinki. The detailed laboratory results show 27 Group 2 eclogite grains, 8 Harzburgitic G10 garnets including a G10(D), 33 Lherzolite G9 garnets, 27 megacrysts and 1 Wehrlitic grain. The presence of the Harzburgitic G10 garnets including a G10 (D) confirms that the sample material is derived from the diamond stability field of the Earth's mantle. GTK diamond specialist Dr. Hugh O'Brien said: "These new results, in addition to the Harzburgitic G10 garnets, contain a significant eclogitic component which could translate into an enhanced diamond potential for the mantle source of these indicator minerals. The fact that eclogite garnets are rare down ice, suggests that the source of the newly discovered Karelian eclogite garnet grains is probably relatively proximal." Karelian chairman Professor Richard Conroy said: "I am delighted with the further significant results from the Kuhmo exploration area in Finland. The presence of eclogite mantle materials is particularly promising as such material is often associated with richer diamond grades. "The prospect of a new kimberlite discovery in this area following on fromthe discovery in Seitaper�¤, where the Company has already outlined the largest diamondiferous pipe yet discovered in Finland, is very encouraging."
