Sunrise Diamonds PLC 19 July 2005 www.sunrisediamonds.com July 19, 2005 KEY KIMBERLITE INDICATORS FOUND AT FIVE MAGNETIC TARGETS IN N. FINLAND •Drill Testing of Priority Targets In Diamond Search To Start Within Days • Indicator Minerals Include Kimberlitic Chromites, Pyrope And Picro-Ilmenites Sunrise Diamonds plc, ('Sunrise Diamonds' or 'the Company') is pleased to announce that drill testing of magnetic targets at its Kuusamo diamond project in northern Finland will start within the next few days. This follows the finding, in early sampling, of kimberlite indicator minerals ('KIMs') including kimberlitic chromites, pyrope garnets, picro-ilmentites, and chrome diopsides. KIMs are minerals typically found in kimberlites, the main primary source of diamonds. The Karelian Craton, a geological block that underlies northern and central-east Finland and a part of neighbouring western Russia, is considered by the Company to be one of the most diamond prospective areas in the world. Over the border this craton hosts the world-class Arkhangelsk diamond deposits, whilst the prospectivity of the Finnish part of the craton has been further enhanced by the announcement by European Diamonds PLC last week of the discovery of a new kimberlite body in central Finland. Since admission to AIM on 6 June the Company has progressed quickly in its evaluation of its untested targets at Kuusamo. A total of 89 surface and basal till samples have now been taken to test for glacial dispersion of possible kimberlite material from a total of 33 magnetic targets. In addition ground magnetic surveys have been carried out at 11 targets. Thirty-one of the till samples have been processed for indicator mineral recovery by the Geological Survey of Finland (GTK) as contractor for Sunrise Diamonds. GTK has commenced preliminary indicator mineral picking and microprobe analyses of selected indicator mineral grains to confirm their kimberlitic parentage. To date KIMs have been found in six samples associated with five of the initial magnetic targets. They include 'kimberlitic' chromites having compositions matching chromites found as inclusions in and inter-grown with diamond, 'kimberlitic' picroilmenites with compositions favouring diamond preservation, pyrope garnet, and chrome-diopsides of mantle origin. Drilling will progressively test priority targets defined by a combination of magnetic anomalies and kimberlite indicator minerals. Indicator mineral sampling and picking is continuing. 'It is particularly exciting to get such positive results so early in the programme and raises an expectation that further kimberlites will be discovered in the Kuusamo area.' commented Patrick Cheetham, Sunrise Diamonds' Chairman, today.
