Drilling Report

Mercator Gold PLC 08 September 2005 MERCATOR GOLD PLC ('Mercator Gold' or the 'Company') 8 September 2005 Indicated and inferred gold resources in Annean JV area increase to 690,100 ounces LONDON - Mercator Gold Plc (AIM, MCR & MCRW) as operator of the Annean Joint Venture ('Annean JV') near Meekatharra, Western Australia, announces a significant increase in indicated and inferred gold resources . • Exploration drilling at Bluebird and Surprise within the Yaloginda mine area of the Annean JV has established indicated and inferred gold resources of 467,000 ounces. More than half of these resources are at a grade of 4.5g/ t Au and all are within 1.5 km of the Bluebird Mill. • The additional gold resources, calculated by Mercator's independent resource consultants, lift the total indicated and inferred gold resources in the Annean JV Area to 690,100 ounces. • Management is highly encouraged by the results and, having expended A$3 million (£1,260,000) on exploration, has notified the joint venture partner St Barbara Mines Ltd that it has now earned a 45% interest and will proceed to Stage 3 of the Joint Venture by spending an additional A$1 million on exploration to secure a 51% interest. The Company is on track to achieve the 51% interest in calendar 2005, well ahead of the March 2007 target date. • The Bluebird global resource is 326,000 ounces comprising 5,280,000 tonnes @ 1.9 g/t, within which are indicated and inferred high grade resources of 1,698,000 tonnes @ 4.5 g/t for 244,000 ounces. The Bluebird resource is from surface. • The Surprise resource is 141,000 ounces comprising indicated resources of 1,220,000 tonnes @ 0.9 g/t and inferred resources of 2,965,000 tonnes @ 1 g/ t. The Surprise resource is from surface. • The new resources bring the Annean joint venture to a total of indicated plus inferred resource of 690,100 ounces gold. • Significant potential exists to increase the resource at Bluebird north and south of the current resource and at depth, and to increase the grade at Surprise with infill drilling of high-grade shoots that produced intercepts such as 15m @ 45.1 g/t and 6m @ 36 g/t. • Commenting on the results, Mercator's Managing Director, Mr Patrick Harford said: 'I'm very pleased with progress to date, in particular the discovery of additional ounces at a cost of just US$7 per ounce. The new resources are the result of our aggressive, geologically focused exploration achieved in less than 12 months from our listing on the AIM market. We are well on track to delineate sufficient quality resources to sustain a long-life mining operation at Meekatharra.' • Full details of the resource estimates have been posted on the Company's website at www.mercatorgold.com For further information please contact: Mercator Gold plc Patrick Harford, Managing Director Tel: +44 (0) 7786 486645 Terry Strapp, Chairman Tel : +61 (0) 8 9322 7422 Michael de Villiers, Finance Director Tel: +44 (0) 2079291010 Julian Vearncombe, Exploration Director Tel: +61 (0) 8 9316 9400 Email: info@mercatorgold.com Web: www.mercatorgold.com Beaumont Cornish Limited Roland Cornish / Felicity Geidt Tel: +44 (0) 20 7628 3396 Ocean Equities Limited Will Slack Tel: +44 (0) 20 7786 4375 King & Shaxson Capital Ltd Nick Bealer Tel: +44 (0) 20 7553 8281 Parkgreen Communications Justine Howarth / Ana Ribeiro Tel: +44 (0) 20 7493 3713 Mercator operates a continuous disclosure policy with respect to exploration results.

Note to editors Mercator Gold plc was admitted to AIM on 8 October 2004, and entered into the Annean Joint Venture with St. Barbara Mines to explore for economic gold resources in the Annean Joint Venture area in the Meekatharra region of Western Australia. Under the terms of the Annean Joint Venture, Mercator Gold Pty Ltd (the company's wholly owned subsidiary) has a right to earn a 45 per cent interest in the Meekatharra Properties by spending AUD$3 million on exploration by 2 March 2006, with a minimum expenditure of AUD$1 million by 2 March 2005. If Mercator earns the 45 per cent interest, it can elect to increase this interest to 51 per cent by spending a further AUD$1 million by 2 March 2007. If Mercator earns the 51 per cent interest, it can elect to increase its interest to 70 per cent by spending a further AUD$ 4 million by 2 March 2009. If Mercator earns the 70 per cent interest, St. Barbara Mines must then contribute pro-rata on any further expenditure or dilute its interest by a standard dilution formula. The Directors have set the Company an exploration target of 2,000,000 ounces of gold contained within four resources, each of at least 500,000 ounces within the Annean Joint Venture area. The Company has reported initial high-grade drilling results from the first two target areas, Bluebird and Surprise.
