Drilling Report

Celtic Resources Holdings PLC 15 October 2002 Celtic Resources reports significant gold grades from diamond drilling programme at Suzdal - Intersections include 33.6m @ 9.6 g/t; 11.7m @ 29 g/t and 12.6m @ 24.6 g/t gold Celtic Resources plc (Ticker CER) today announced encouraging drilling results at its 1.6 million ounce Suzdal gold mine in Kazakhstan (100% owned). Drilling was in the sulphide ore zones, which are a continuation of the currently mined oxide ore bodies. The programme aims to delineate the Number 1 and Number 3 ore bodies and confirm gold grades. In the 2002 programme, the relevant diamond drill results to date include: Intersection Thickness Gold grade Orebody 1 (m) (m) (g/t) Hole Number 461 34.9 - 41.7 6.8 43.6 463 10.0 - 43.6 33.6 9.6 469 130.0 - 137.5 7.5 6.7 470 172.2 - 177.0 4.8 13.6 472 174.9 - 186.6 11.7 29.0 Orebody 3 466 80.6 - 83.6 3.0 11.4 467 88.7 - 101.3 12.6 24.6 468 132.0 - 136.1 3.1 98.2 Note: The results indicate apparent depths and thicknesses in almost vertical orebodies intersected by drilling at an angle of 60 degrees. Samples of split core were taken at 1m intervals and quoted gold grades are uncut. Managing Director, Mr Kevin Foo, said today "these are excellent results which confirm high grade mineralisation and the extension of the ore bodies at depth. We remain on target to complete an internal development plan for the sulphide ores by December 2002 at which time we shall also announce revised ore reserve and resource figures. Subject to finance, we would then plan to have the sulphide project on stream by 2004 which will produce 130,000 oz per year for more than 10 years" he added. Suzdal has been in operation since 1999 with 2001 production from the oxide ores being 43,000 ounces at a total cost of US$140/oz. Additional oxide dumps at Suzdal, estimated to contain some 14 million tonnes at 0.8 to 1.0 g/t Au may be able to be economically treated and internal studies are being completed on this project. These resources are not included in the current 1.6million ounce reserve. In relation to the sulphide ores, preliminary economic and technical studies have highlighted the below: • The sulphide ores can initially be mined by open pit and then underground. It is expected that sulphide ore production would build up gradually to 500,000 tpa and production from the sulphide plant is expected to be 130,000 oz/yr gold; • The sulphide ores are refractory and will require metallurgical processes such as flotation and bacterial leaching to recover gold. Overall estimated gold recoveries will be about 80%-90%. • Capital expenditure for the sulphide plant is estimated to be US$12 million with first production from the plant targeted for mid 2004 subject to financing; • Operating costs are expected to range from US$130 to US$160/oz. Based on the above factors, Celtic believes that the project economics are attractive. With two years of operating experience at this mine, full ownership and a trained and motivated workforce, Celtic is well positioned to develop the sulphide project successfully.
