Resource Estimate

Ariana Resources PLC 10 May 2007 10 May 2007 AIM: AAU INITIAL JORC RESOURCE AT KIZILTEPE Ariana Resources plc ('Ariana' or 'the Company'), the gold exploration company focused on Turkey, is pleased to announce the completion of the Company's first independent resource estimate for the Kiziltepe gold prospect, at its flagship Sindirgi Project in Balikesir Province, western Turkey. Highlights •SRK Consulting (UK) Ltd ('SRK') estimates a JORC compliant mineral resource of 99 koz Au + 1,820 koz Ag (for 135 koz Au equivalent) •Resource based on two veins which comprise only 5% of the mapped veins at the property •Mineralisation is open at depth and along strike and additional targets require further drill-testing in 2007 •SRK recommends initiation of a formal scoping study to evaluate production options at Kiziltepe SRK has completed a 3D model and mineral resource estimate in compliance with the JORC code for certain gold bearing quartz veins at the Kiziltepe prospect. SRK commented, 'Ariana has completed over 4,150m of drilling and 250m of channel sampling at surface .... and has ensured a high quality of sample preparation and laboratory results. These have resulted in grade and density data which can support a JORC compliant resource estimate.' Four mineralised structures have been incorporated in the 3D geological model, namely: Arzu South, Arzu North, Vein 4 and Banu Vein. The majority of the current resource is located within Arzu South, the central part of which has been drilled and channel sampled sufficiently enough to support an Indicated Mineral Resource. The southern and northern parts of Arzu South and a small part of Arzu North comprise the Inferred Mineral Resource. Much of Arzu North, Vein 4 and Banu Vein have not been modelled as part of the mineral resource due to lower drill data density and grades. At Arzu South, SRK has provided a detailed interpretation of the drillcore intersections to produce a geological model consisting of multiple vein segments, many of which have been delineated robustly by Ariana's drilling. Over the 800m strike length in consideration at Arzu South, ten mineralised vein segments have been modelled, with vein widths typically between 1.5 and 5m. SRK has placed a depth limit of approximately 125m to the model, as most drill intersections are above this level and it is unlikely that material below this level would be taken by an open pit. A 3 g/t Au cut-off grade has been applied to the resource blocks which measure 25 x 25m in the plane of the modelled structures. The parts of the model which are above cut-off grade are generally continuous and, within these, higher grade features appear to plunge to the southeast. SRK Mineral Resource Statement Classification Vein Tonnage Grade Metal * (Kt) (Au g/ (Ag g/t) (kg Au) (kg Ag) t) Indicated Arzu South 200 5.8 98 1,160 19,600 (C) Inferred Arzu South 70 4.0 70 280 4,900 (N) Inferred Arzu South 180 8.0 160 1,440 28,800 (S) Inferred Arzu North 50 4.0 65 200 3,250 * Equivalent to 135,400 oz gold equivalent. The gold equivalent is calculated on the basis of a 50:1 Ag:Au price ratio (this price ratio fluctuates and is dependent on market conditions). SRK considers there to be good potential to upgrade the Inferred Mineral Resources to Indicated Mineral Resources at Arzu South by additional drilling. In addition to this, the Arzu South vein system has some potential to be extended at depth, and considerable potential to be extended along strike. Depth extension drilling must now focus on the potential down-plunge continuation of zones of high metal accumulation. Further, SRK considers there to be reasonable potential to define, by further drilling, higher grade zones within other veins and to delineate additional mineralised structures on the property, which have not yet been found in outcrop due to field clearing. In addition to undertaking further drilling, SRK has also recommended an evaluation of options for the extraction of the current resource by undertaking a scoping study. Some options that will be considered as part of the scoping study include: 1) A low-cost heap leach on site; 2) A small-scale milling and gravity / cyanidation plant, ultimately producing dore on site; 3) A trucking operation delivering mineralised material or concentrate to an operating gold mine for toll treatment or direct sale. Kerim Sener, Managing Director, commented: 'This is the first independent resource statement published by the Company and it confirms the potential of the Kiziltepe prospect. As Arzu South is only one of several identified targets, we consider there to be significant scope to further expand the resource.' 'We are very encouraged by the results to date and further drilling is planned to define the full potential of the prospect. We aim to proceed with the recommendation of SRK to evaluate our production options at Kiziltepe, and as a first step we have commenced formal test work to define the metallurgical characteristics of the mineralisation.' 'The drilling results from our initial exploration programme have produced positive results on a number of our prospects and we expect to be in a position to increase our mineral resource base in due course.'

Kiziltepe lies approximately 100km east of the one million ounce vein-hosted Ovacik gold mine and 115km northwest of the five million ounce Kisladag gold mine. The prospect hosts over 20km in strike length of gold-silver bearing low-sulphidation epithermal quartz veins across an area of at least 3km by 1km. Individual veins are exposed for up to 700m and widths vary between 1m and 14m. The main veins trend northwest, dip to the northeast and are hosted within Miocene age dacitic volcanic rocks. Ariana acquired the Sindirgi Gold Project from Newmont Mining Corporation (NYSE & ASX: NEM; TSX: NMC) in March 2005. Newmont retains the right to a royalty of up to 2.5% on future gold production from the Sindirgi gold project. Ahead of commencing the drilling programme, Ariana obtained all necessary environmental and forestry approvals from the provincial government in Balikesir and the State Government in Ankara. Sampling and Assaying Procedures Ariana's sampling of drill core and surface samples conforms to industry best-practice. Laboratory sample preparation, assaying procedures and chain of custody are appropriately controlled. Preparation of samples is undertaken by ALS Chemex in Izmir and assayed for gold by 30g fire assay at the ALS Chemex laboratory in Romania. Routine re-assaying of samples assaying greater than 10 g /t Au and 100 g/t Ag has also been completed by ALS Chemex. Standard, blank and duplicate samples are being used in the sample batches in line with the Company's quality control procedures. Quality control checks have determined excellent performance of blanks and standards, and duplicate samples have shown very high correlations. The Company maintains an archive of half core samples and a photographic record of all cores for future reference. Statement of Qualification Martin Pittuck, MIOM3, C.Eng, a Principal Resource Geologist at SRK with over 10 years experience in Mineral Resource estimation for gold deposits, has overseen the preparation of this estimate. He is considered to be a competent person for the purposes of reporting Mineral Resources in accordance with the terminology and guidelines given in the JORC Code.
