Karelian Diamond Resources plc (“Karelian Diamonds”) (AIM: KDR), is pleased to announce the micro-diamond results on drill core from the previously untested Eastern Lobe of the Lahtojoki two hectare diamond deposit over which the Company holds a mining concession.

The analyses, performed by Microlithics Laboratories Inc. in Thunder Bay, Canada have yielded micro-diamond results comparable to those for the smaller Central and Western portions. The results indicate the potential for high quality diamonds of good colour and shape.


Professor Richard Conroy, Chairman, Karelian Diamond Resources plc commented:

These early-stage results not only serve to confirm the validity of earlier analyses by a previous operator, but also indicates that the grade, modelled at 40 carats per hundred tonnes from past micro-diamond results, could be reasonably extended into the Eastern Lobe of the Kimberlite at depth. As such they give the Company increased confidence in an economically robust project, as outlined in the PEA undertaken in 2017.”
