Karelian Diamond Resources plc has received “positive” kimberlite indicator minerals results from till samples excavated at the green diamond target area in the Kuhmo region, Eastern Finland.

The kimberlite indicator minerals (KIM) were found in 19 of 21 till samples, up-ice of the green diamond discovery.
Sampling was also conducted as close as possible to the “presumed kimberlitic source zone, along the kimberlite indicator mineral train”.
Returns include a total 74 purple to red peridotitic garnets (G9/G10 pyropes), nine of which are 0.5 to 1.0 mm, two orange mantle garnets, four chrome diopsides and 81 chromites.
“The highest KIM counts were achieved in three highly anomalous basal till samples, containing a total of fifty-nine purple to red peridotitic garnets, two orange mantle garnets and nineteen chromites,” said Karelian.
“The fourth-best KIM count was achieved in a surface till sample, also including one pyrope of the large range.”
Given that further excavated sampling is prevented by the thickness of the overburden, Karelian plans to continue exploration by drilling.
Managing director Maureen Jones added: “We are very encouraged by further excellent kimberlite indicator mineral results highlighting the recently electromagnetic anomaly as a potential source of the green diamond.”
