Exploration Update

Glencar Mining PLC 13 April 2004 Glencar Mining plc 13 April 2004 Glencar Mining plc ('Glencar' or the 'Company') Glencar Announces Exceptional Sample Assay Results from Sankarani Project, Mali Glencar is pleased to announce the results of the first phase soil and rock-sampling programme at Farasaba, in its Sankarani Project in Southern Mali. The assays have returned some exceptionally high gold values within a broadly anomalous, NW-SE trending zone, some 2.5 kilometres long and which is open at either end. Values of up to 32,410 ppb (32.4 grams per tonne) have been received with other exceptionally high values of 28,740 ppb (28.7 grams per tonne) and 23,814 ppb (23.8 grams per tonne) also being recorded. Glencar's initial geological prospecting on the Sanakarani Project has identified a number of target areas with favourable geology/structure, geochemistry and/or active artisanal workings. The recently completed sampling programme at Farasaba was centred on an area of active artisanal activity which showed extensive alteration of the rocks in the vicinity of the mineralised zones. Sampling was carried out on a 100m x 100m grid over an area of 4 square kilometres and approximately 475 samples were collected and analysed by fire assay for gold. Satellite imagery interpretation has identified the presence of NW-SE trending structures in the region and also cross cutting E-NE trending structures. Most of the high values were recorded in soil samples while the value of 28,740 ppb was returned from a laterite sample. All soil samples were collected at depths of between 35 centimetres and 50 centimetres, while the laterite samples were collected at depths of approximately 10 centimetres. This Farasaba Prospect is part of a 500 square kilometre licence area in which Glencar is in the process of earning an 85% interest through exploration expenditures and the issue of up to 1.5 million shares over a four-year period. A further 500 square kilometre licence area, adjacent to and north of the existing area, will be issued shortly in which Glencar has also the right to earn an 85% interest through further exploration expenditures and the issue of up to a further 1.5 million shares over a four year period. These exceptionally encouraging results from this, Glencar's first field sampling programme in Mali, confirm the potential for the discovery of economic gold mineralisation at Farasaba and elsewhere within the 1,000 square kilometre area of our Sankarani Project.
