Kansai Mining Corporation - Sampling and drilling update on Natal project Venezuela

PR Newswire

1.2 Tonne in-situ pit sample yields 1.98 carats of diamonds

PAYSON, AZ, June 4 /CNW/ - Kansai Mining Corporation ((TSX-VEN:KAN) is

pleased to announce the results of the test sample commissioned at the extreme south-western end of the Belmudez Zone at Natal in the Guaniamo Diamond Field in Venezuela. A random pit, measuring 1m x 1m x 0.5m depth was hand-dug by the company on one of the proposed drill-lines at the south-western extremity of the Belmudez Zone, characterised by shallow artisanal workings and a large south- easterly trending co-incident magnetic and radiometric anomaly. The zone has a known strike length of more than 900 meters from the extensive trials which are rarely more than one meter in depth and the anomalous zone extends for at least 1.4km along strike. The pit was dug more than 500 meters south of the last observed shallow pits and trials of the local artisans. The sample was estimated to weigh approximately 1.2.tonnes. It was concentrated with the aid of local diamond- pans and jigs, following sluicing of the coarser material. Recoveries in such equipment are known to be somewhat inaccurate and lower than when treated with more sophisticated plant. The concentrate, nevertheless contained 10 macrodiamonds, varying in size from 0.02 carats to 0.61 carats for a total weight of 1.98 carats. The five smaller diamonds comprise a total weight of 0.17.carats, with the larger goods at 0.17, 0.29, 0.29, 0.45 and 0.61 carats respectively; 4 of the 5 larger stones are of gem quality as are 2 of the small fraction. The company views this sample as stemming from in-situ outcrop in a location previously unexploited and undiscovered by local workers. It is therefore encouraged by a grade of 1.65 carats per tonne but until more work can be undertaken in the forthcoming dry season recognises that this limited test is not representative. The drilling programme is nearing completion and results from that work will be reported as soon as practicable following analysis and logging which customarily takes several weeks.
