The reservations include one exploration claim in the Kuupio-Kaavi region and two claims in the Kuusamo region, situated in the north-east of Finland, south of the Arctic Circle and bordered to the east by Russia.
Kuupio-Kaavi is located in central Finland and is an established diamondiferous region.
Karelian said that a claim reservation gives it exclusive rights to apply for exploration claims within the area.
The company applied for the reservations by analyzing airborne geophysics together with till sampling and integration data made available under its agreement with Rio Tinto Mining and Exploration.
Karelian Diamond Resources chairman Richard Conroy said, "We are delighted to have been granted these additional claim reservations in regions of Finland that we believe to be highly prospective for diamonds."
Karelian noted that kimberlitic indicator minerals were recovered in till samples in all three reservations and that further studies showed the presence of diamondiferous kimberlitic indicator minerals.
