KUHMO SAMPLE MATERIAL CONFIRMED TO BE FROM DIAMOND STABILITY FIELD

Karelian Diamond Resources plc (“Karelian Diamonds”) (AIM: KDR), is pleased to announce that Electron Probe Microanalyzer (EPMA) results on sample material taken up ice (as announced 23 January 2018), from where the Company discovered a green diamond in till (as announced 31 January 2017), has confirmed that the sample material contains indicator minerals derived from the diamond stability field of the Earth’s mantle.

The results showed 2 Group I and 4 Group II eclogite garnets, 6 Harzburgitic G10 garnets, 34 Lherzolite G9 garnets, 6 megacrysts, 4 Di Chromites, 3 Ti Chromites and 1 Cr Chromite.

The presence of Group I eclogitic garnets is significant as eclogites raise the potential for a diamondiferous source.

Group II eclogitic garnets may also be associated with the presence of diamonds as may G10 and G9 garnets.

The relevance of these EPMA results on the sample material is that some garnets are created under similar conditions to diamonds within the ultramafic mantle rocks underlying the crust and so are used as predictors of the possible presence of diamonds.

The sample material was analysed by EPMA at the Geological Survey of Finland laboratory in Espoo.

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

“These new results confirm that the sample material from up ice of the diamond find may come from a diamondiferous source and is a further encouragement for our diamond exploration programme in the Kuhmo area.”

This release has been approved by Kevin McNulty PGeo, who is a member of the Company's technical staff and holds a BSc/MSc in Geology and Remote Sensing, in accordance with the guidance note for Mining, Oil & Gas Companies issued by the London Stock Exchange in respect of AIM Companies, which outlines standards of disclosure for mineral projects.
