Exploration Update

AIM: KEFI 12 September 2007 KEFI Minerals Plc ("KEFI Minerals" or the "Company") GOLD DISCOVERY AT THE ARTVIN PROJECT KEFI Minerals is pleased to announce a gold discovery at the Yanikli Prospect and related exploration progress at the Company's 100%-owned Artvin Project, northeastern Turkey. Highlights * Channel sampling has returned 12m at 5.0g/t gold within a broader zone containing 37m at 1.8g/t gold in silica-altered zone at the Yanikli Prospect. * Mapping has revealed that the silica-altered zone at Yanikli has a strikeof at least 1km and a width of 40m to 100m. * Regional geological mapping and geochemical data are being integrated and interpreted with more than 15new targets recently defined in the Artvin Project area. Exploration Results KEFI Minerals commenced exploration in the Artvin Project area in May 2007. Exploration work completed to date has included 83 stream sediment samples and 225 rock-chip and channel-chip samples. Copper anomalies (>100ppm copper) generated from stream-sediment sampling have focussed exploration to the 25km2 Uzumlu Prospect area which contains numerous historical mine workings, clay-pyrite alteration with base-metal sulphide veining and stratigraphically controlled silicification. In addition, recent channel-chip sampling at the Yanikli Prospect (4km south of Uzumlu) has returned 37m at 1.8g/t gold, including 12m at 5.0g/t gold. These samples were taken at nominal 2m and 5m intervals from silica-altered volcanic rocks. Multi-element results are pending, however visual observations indicate this zone contains 1% to 2% zinc sulphide (sphalerite) and lead sulphide (galena) minerals as well as trace concentrations of copper sulphide (chalcopyrite) minerals. Further channel-chip sampling along available road cuts and rock outcrops is currently being undertaken at the Yanikli Prospect, as well as soil sampling on a 200m by 50m grid. Reconnaissance geological mapping has delineated a large 1km long by 40m to 100m wide silica-pyrite alteration zone in an area of rugged topography. This zone remains open along strike. Detailed structural and alteration mapping has commenced around numerous small underground mine workings in the Artvin Project area. This data has been integrated with new stream sediment geochemistry results, digital elevation models and remote sensing alteration data (ASTER). Synthesis of this information has produced a consistent structural model that explains the controls on mineralisation at the historical mines, explains the location of and the geometry of recently mapped zones of hydrothermal alteration (of up to 4km2 at the Uzumlu Prospect) and generated more than 15 new prospects in the Artvin Project area. Project Summary and Geology The Artvin Project is 100%-owned by KEFI Minerals and is located in the eastern part of the Eastern Pontides region, which is dominated by Jurassic-Tertiary island arc magmatic rocks formed on the Palaeozoic basement. The Artvin Project comprises 15 Exploration Licences which cover a total of 253km2. The Pontides belt is prospective for volcanic-hosted massive sulphides ("VHMS") deposits, porphyry copper-gold deposits and epithermal gold-silver mineralisation. Nearby mines and prospects are within 10 to 100km along strike from the Artvin Project include: * Cayeli with reserves of 11.6 million tonnes at 3.6% copper, 5.9% zinc, 0.6g /t gold and 49g/t silver (owned by Inmet Mining), * Murgul with reserves of 80 million tonnes at 1.1% copper; * Cerateppe with reserves of 1.6 million tonnes at 8.8% copper, 1.1% zinc, 1.4g/t gold and 33g/t silver (owned by Inmet Mining); and * Berta porphyry copper-gold prospect owned by Nuinsco Resources and Xstrata Copper. The Artvin Project area consists of large areas of hydrothermal alteration and numerous, small historical base-metal mines. These were exploited by Turkish and Russian miners during the last 150 years. More recently, in the 1990s, the area was explored for copper by Rio Tinto, Placer Dome and BHP, however exploration work was largely reconnaissance in nature. Nuinsco Resources are currently exploring the large Berta porphyry copper-gold prospect which is located adjacent to the southwest corner of the Artvin Project area. KEFI Minerals is the first company to utilise modern exploration methods to systematically explore the Artvin Project area for gold. KEFI Minerals' Managing Director, Jeffery Rayner, commented: "The gold discovery at Yanikli is very promising both as a potential area of development in its own right and to further support our opinion of the wider prospects of the area. Work at the Artvin project continues apace and we have defined more than 15 new targets in the area. KEFI Minerals is the first company to utilise modern exploration methods to explore for gold in the region and we are encouraged by our progress to date."

Notes to Editors: KEFI Minerals was formed on 24 October 2006 for the purposes of holding EMED Mining's exploration interests in Turkey and Bulgaria with a view to creating shareholder value through the discovery and exploitation of gold and copper deposits. In November 2006, KEFI Minerals completed the acquisition of EMED Mining's Turkish and Bulgarian exploration interests through the acquisition of EMED Mining's subsidiary Mediterranean Minerals (Bulgaria) EOOD. In addition, KEFI Minerals acquired from EMED Mining a database of mining information relating to Turkey. KEFI Minerals commenced trading on AIM on 18 December 2006, following the successful placing of 46,666,667 shares at 3p to raise £1.4 million. In Turkey, KEFI Minerals has six exploration projects: 1. At Derinin Tepe in the Western Anatolia Region, epithermal quartz veins have been identified with gold and silver mineralisation. 2. At Artvin in north-eastern Turkey, areas of extensive hydrothermal alteration have been recognised in the project area, and there is evidence of historical workings indicating potential for economic mineralisation. 3. At Gumushane in eastern Turkey, areas of extensive hydrothermal alteration have been recognised in the project area, as well as coincident areas of interest identified through interpretation of Aster data. 4. At Karalar, in Central Anatolia, highly anomalous gold in stream sediments have been identified in an area of historic base metal mines. 5. Muratdag, in Western Anatolia, is prospective for Carlin-style epithermal gold mineralisation. 6. Meyvali, in Western Anatolia, is prospective for epithermal and skarn related mineralisation. KEFI Minerals also has an extensive exploration database which contains information about approximately 100 further prospective sites in Turkey. This database provides the Company with a competitive advantage to identify prospective areas for project generation in Turkey. Monitoring of the exploration licence status of geologically prospective areas will be carried out on an ongoing basis so that KEFI Minerals can acquire further exploration opportunities as soon as they become available. EMED Mining has agreed to provide technical and administrative systems and personnel to KEFI Minerals on a cost-recovery basis, thus enabling KEFI Minerals to reduce overheads and spend more on exploring Turkey and Bulgaria. KEFI Minerals' Board of Directors is comprised of Mr. Harry Anagnostaras-Adams (Chairman), Mr. Jeffrey Rayner (Managing Director), Professor Ian Plimer (Deputy Chairman) and John Leach (Finance Director). Further information on KEFI Minerals is available at www.kefi-minerals.com and the Company's AIM code is "KEFI". -Ends-
