Kepez Bulk-Sample Results
(Thomson Reuters ONE) - 3 September 2009AIM / PLUS Markets: AAU KEPEZ METALLURGICAL AND BULK-SAMPLE RESULTSAriana Resources plc ("Ariana" or "the Company"), the goldexploration and development company focused on Turkey, is pleased toannounce the results of bulk-sampling and laboratory-scalemetallurgical testwork conducted on material from the Kepez GoldProspect in Balikesir Province, western Turkey.Highlights: * Recoveries of up to 89% and 95% on high and average grade material * High grade bulk-sample yields 16.95 g/t gold and 117 g/t silver * Average grade bulk-sample yields 6.83 g/t gold and 72 g/t silver * Thickness of mineralised broken rock estimated to be 2-3mDr. Kerim Sener, Managing Director, commented:"These metallurgical results confirm our expectations that the Kepezmineralisation is metallurgically akin to the material alreadytest-mined at Kiziltepe. The bulk-samples collected from the Kepezprospect have confirmed the potential for a high average grade withinthe mineralised zone. Drilling of the area provided an estimate ofthe thickness of the scree covering the vein of about 3m, whichconfirms earlier expectations and demonstrates the potential foraround 25,000 tonnes of broken mineralised rock."These results demonstrate that the Kepez prospect is likely to yielda resource of high grade material amenable to simple mining andprocessing at an established facility. The resource potential of theKepez prospect will now be evaluated in future programmes andintegrated within the development work being undertaken at theKiziltepe deposit."Details of ProgrammeTwo bulk-samples totalling approximately 100 kg were collected fromthe Kepez prospect, which is located 6.5km ENE of the Kiziltepedeposit. One sample contained material known to represent theaverage grade of mineralisation at the prospect (7.14g/t Au) and thesecond sample contained material representative of the highest gradeportions of the prospect (17.21g/t Au). This sampling followed theearlier grid sampling undertaken on the prospect and detailed in theannouncement of 13th May 2009.These samples were processed at the Eti Gümüs A.S. ("Eti") laboratoryunder similar conditions to the testwork undertaken on material fromKiziltepe. The Kepez material was crushed and milled to 80% passingat 20 micron (the standard size fraction used at the Eti processingplant). The material was leached over a period of 32 hours andreagent consumption was moderate in both cases (e.g. between 0.17 and0.51 kg/t NaCN).The high grade sample provided a head grade of 16.95 g/t gold and 117g/t silver and the average grade sample provided 6.83 g/t gold and 72g/t silver. Over the 32 hour leach period, the measured recovery ofgold and silver from the high grade sample was 89.0% and 51.3%respectively. The recovery of gold and silver from the average gradesample was 95.2% and 80.6% respectively. These recoveries are inline with the recovery of gold and silver reported fromlaboratory-scale testwork on material from the Kiziltepe deposit.Due to the nature of the scree covering parts of the vein at Kepez, adrilling programme was designed to provide clarity on the potentialthickness of the broken rock. Based on the performance of thedrilling rig, this blanket of broken rock and heavily fracturedground is estimated to be 2-3 m in the areas drilled. This matchesthe figure provided by visual estimation of the outcrop area. Thebroken ground, containing an average surface grade of 7.14 g/t Au, isestimated to cover an area of 3200m2, which suggests potential forabout 25,000 tonnes of material amenable to simple mechanicalmining. The Company is presently considering how best to calculate aJORC compliant mineral resource for this area.Contacts:Ariana Resources plc Tel: 020 7407 3616Michael Spriggs, ChairmanKerim Sener, Managing DirectorBeaumont Cornish Limited Tel: 020 7628 3396Roland CornishAlexander David Securities Limited Tel: 020 7448 9820Nick Bealer / David ScottLoeb Aron & Company Ltd Tel: 020 7628 1128Peter Freeman / Frank LucasEditors' note:Dr Kerim Sener, BSc (Hons), MSc, PhD, is the Managing Director ofAriana Resources plc.

Kepez lies 6.5km awayfrom the current trial production area in the Kiziltepe Prospect. Ariana is currently assessing the potential of Kepez to yield asmall high-grade resource amenable to open-pit mining.The prospect contains 3km of gold-silver bearing low-sulphidationepithermal quartz veins across an area of at least 2km by 0.5km. Individual veins are exposed for up to 600m and widths vary between2m and 25m. The main veins trend N and NE, and are hosted eitherwithin Lower Miocene dacitic volcanic rocks or on the boundarybetween these rocks and underlying Upper Cretaceous ophioliticsedimentary rocks. Three main vein systems have been defined bygeological mapping, rock-saw channel and rock-chip sampling, the mostimportant of which is the Karakaya Vein.Existing drilling on the Karakaya Vein shows that it dips between40 and 50 degrees to the west and is developed along the contactbetween underlying ophiolitic rocks and overlying dacitic volcanicrocks. The Karakaya Vein was sampled during a rock-saw channelsampling programme conducted along the vein outcrop in 2006. Surfaceresults on the Karakaya vein have been encouraging over 100m ofstrike, from which high grades have been encountered, althoughprevious follow-up drilling of the down-dip extensions have tended toencounter lower grades.About Ariana ResourcesAriana is an exploration and development company focused onepithermal gold-silver and porphyry copper-gold deposits in Turkey.The Company is exploring a portfolio of prospective licences selectedon the basis of its in-house geological and remote-sensing database,on its own in western Turkey and in Joint Venture with EuropeanGoldfields Limited in north-eastern Turkey.The Company's flagship assets are its Sindirgi and Tavsan goldprojects. Both projects contain a series of prospects, within twoprolific mineralised districts in the Western Anatolian Volcanic andExtensional (WAVE) Province in western Turkey. This Province hoststhe largest operating gold mines in Turkey and remains highlyprospective for new porphyry and epithermal deposits. These coreprojects, which are separated by a distance of 75km, are presentlybeing assessed as to their economic merits. The total resourceinventory of the Company stands at 401,000 ounces of goldequivalent.Loeb Aron & Company Ltd. and Alexander David Securities Limited arejoint brokers to the Company and Beaumont Cornish Limited is theCompany's Nominated Adviser.For further information on Ariana you are invited to visit theCompany's website at www.arianaresources.com.Ends---END OF MESSAGE---This announcement was originally distributed by Hugin.
