Karelian Diamonds Resources PLC (LON:KDR) has started fieldwork at the licence adjacent to its Lahtojoki deposit in Finland.
Kimberlite boulders have previously been discovered in the Lahtojoki South area, said Karelian, and the programme is designed to recover these.
Analysis has shown that the boulders are a type of Kimberlite unlikely to be derived from the Lahtojoki kimberlite and are likely to have originated from a yet to be discovered kimberlite body, up ice from the initial discovery site.
The current programme is designed to recover further kimberlite boulders and to delineate the glacial direction, with a view to identifying the source of the kimberlite boulders.
Professor Richard Conroy, Karelian chairman, said: “I am delighted that it has been possible to start the exploration so soon after the granting of rights of way.”
