Karelian Diamond Resources plc said it had indications of the likely source of its green diamond discovery and the potential of the Kuhmo licence in Finland.
DEEP MANTLE
Electron microprobe analysis results of 60 Kimberlitic garnets, taken from till samples up-ice of the discovery, point to the presence of a “diamond stability field”.
The presence of diamond stability field garnets and other diamond-facies garnets was a “clear indicator” of the diamond potential of the Kuhmo target area, added Karelian.
“The microprobe analysis resulted in the identification of 19 G10 harzburgitic, 19 G9 lherzolitic, 15 G5 pyroxenitic and seven G4 eclogitic garnets.
“The discovery of the green diamond down-ice, together with the abundance of G10 harzburgitic garnets, including G10Ds, and the presence of eclogitic G4 garnets, including G4Ds, and pyroxenitic G5D garnets, all indicate a deep-mantle source for kimberlite originating from the diamond stability field where diamonds are formed.
“The results indicate that two of the sample locations are likely to be very close to the kimberlitic source of the green diamond.”
Karelian is also exploring for diamonds at Lahtojoki in the Kuopio Kaavi region of Finland.
The Finnish Land Court will hear appeals by two landowners on 21 May over the amount of their expected compensation and the boundary of the diamond mine development.
