Drilling Report

Glencar Mining PLC 19 January 2004 Glencar Mining PLC 19 January 2003 Glencar Mining plc ('Glencar' or the 'Company') Drilling Report Summary Glencar is delighted to announce that the short, first pass Reverse Circulation drilling programme completed in December on the previously undrilled Atinasi and Tanaya prospects in the Asheba concession in Ghana confirmed the presence of extensive near surface ore grade gold mineralisation. The results also suggest significant potential for economic tonnages. At Atinasi North, the best intersection was 23.5 grams per tonne over a width of 3 metres, and finishing in mineralisation at the bottom of the hole. At Tanaya, the best intersection was 4.18 grams per tonne over a width of 3 metres. We have successfully completed this first phase of the drilling programme on the Atinasi - Tanaya Trend which confirmed the presence of economic grades of gold. The next drilling programme will be directed at proving the nature and continuity of ore grade mineralisation at greater depths, beneath the current extent of artisanal mine workings. The very existence of these mine workings, more extensively developed than previously recognised, indicates the relatively continuous and higher grade nature of the mineralisation in this zone. It augurs well for the potential of this structure at deeper levels. It is planned, subject to drill rig availability, to commence this deeper drilling programme in March. A summary of the more significant mineralised intersections is given in the tables below. Rock and Auger Sampling Geological mapping, rock and shallow auger sampling, carried out during 2003, led to the delineation of a significant, 3 kilometre long, mineralised zone, referred to as the Atinasi-Tanaya Trend. The area is underlain by rocks of the mineralogically prolific Upper Birimian system. At both Atinasi North and Tanaya, zones of high grade, auriferous quartz veinings within highly altered basaltic rocks were identified. During October, a short rock-sampling programme around artisanal workings on these structures was completed. In the Atinasi area, 29 samples were collected. Of these, 23 were mineralised with an average grade of 4.8 grams per tonne. The maximum grade was 44.2 grams per tonne which was returned from a 1 metre channel sample taken from the wall of an existing shaft. At Tanaya, 20 samples were assayed of which 17 were mineralised with an average grade of 3.0 grams per tonne and a maximum grade of 16.9 grams per tonne in a grab sample collected from an artisanal shaft. Drilling The recently completed shallow drilling programme was designed to test the near surface extent of mineralisation at Atinasi North and at Tanaya, some 2.5 kms apart. A deeper drilling programme, designed to give an indication of potential gold resources within the overall zone will now follow. A total of 1253 metres of drilling was completed, 1,042 metres at Atinasi North and 211 metres at Tanaya. Samples were collected at 1 metre intervals and laboratory assays were carried out over the entire length of each hole in 3 metre composite sections. We have identified 7 of the holes at Atinasi North, where intersection of, or proximity to underground workings impacted on recoveries within mineralised zones. While in theory lost sample recovery can impact either positively or negatively on returned sample grades we believe that in these holes the grades reported are likely to understate the actual in situ grade either because the higher grade material was mined out or the mineralised sample was not recovered because of air loss through the adjacent, relatively shallow excavations. Atinasi North Many of the holes in Atinasi North finished in mineralised material. For instance, borehole AKDL20 intersected 23.5 grams per tonne gold over a 3 metre width from 36 metres to the bottom of the hole at 39 metres depth. This indicates a high grade, mineralised structure at this location which is at least 3 metres wide. It is anticipated that, with deeper drilling, below the level of shallow workings, this will not prove to be an exceptional intersection at Atinasi North. Boreholes AKDL 22, 24 and 25 also finished at 39 metres depth in mineralised material.

However, significant mineralised intersections were encountered in three of the six holes, AKDL 28,29 and 31 and these are given in the table below. In Tanaya, as at Atinasi North, each of the significant mineralised zones intersected included zones of poor recovery associated with artisanal workings and as is the case at Atinasi, we believe the actual in situ grades are likely to be higher than reported.
