Revised JORC Resource at Kiziltepe

31 July 2008 AIM / PLUS Markets: AAU JORC RESOURCES INCREASED AT KIZILTEPE Ariana Resources plc ("Ariana" or "the Company"), the gold exploration and development company focused on Turkey, is pleased to announce a further increase to its resource estimate for the Company's Kiziltepe gold prospect, at its flagship Sindirgi Project in Balikesir Province, western Turkey. The total resource has increased to approximately 186,000 ounces of gold equivalent. Highlights * SRK Consulting (UK) Ltd ("SRK") estimates a JORC compliant mineral resource containing Measured and Indicated Mineral Resources of 104,000 oz (Au) and 1,700,000 oz Ag (138,000 oz Au equivalent) and an Inferred Mineral Resource of 34,000 oz Au and 725,000 oz Ag (48,000 oz Au equivalent) * Measured and Indicated Mineral Resources comprise approximately 75% of the total metal resource * Global resource now 950,000 tonnes at an average gold equivalent grade of 6.1 g/t, representing a 40% increase in tonnage over the previous resource estimate * Additional drilling planned to add further near surface resources to the inventory Dr. Kerim Sener, Managing Director, commented: "This additional resource update for Kiziltepe was prepared during and following a visit to site last week by our consultants SRK. The estimate is based on all of our drilling up to March 2008 and utilises certain findings from the mining options study undertaken by Wardrop Engineering. "The available drilling data for Arzu South has been remodelled to determine the broader exploration potential of the vein system at depth and to further refine our understanding of the structural controls on mineralisation. We are particularly encouraged to note that the model generated identifies several steeply plunging shoots of higher grade mineralisation which have not been adequately tested by drilling. "We are now planning for focused exploration over certain areas within the Kiziltepe prospect in the expectation that our resource can be increased even further. Drilling at Kiziltepe will recommence in August using our in-house drilling team on veins that have not been drill-tested to date. We remain committed to outlining a commercially feasible resource." Resource Statement SRK has completed a 3D geological model and mineral resource estimate in compliance with the JORC code for several gold-bearing quartz veins at the Kiziltepe prospect. SRK commented, "Ariana.has ensured a high quality of sample preparation and laboratory results, resulting in grade and density data which can support a JORC compliant resource estimate." Four mineralised structures have been incorporated into the resource model, namely: Arzu South, Arzu North, Banu and Derya (previously known as Vein 4). The majority of the current resource is located within Arzu South, the central part of which has been drilled and channel sampled with sufficient density to support a Measured Mineral Resource. Parts of the southern and northern areas of Arzu South and the southern portion of Arzu North are in the Indicated Mineral Resource category. The remaining part of Arzu North and all of Banu and Derya comprise the Inferred Mineral Resource. SRK has placed a depth limit of approximately 125m to the resource model, as most drill intersections are above this level and it is clear that material below this level would not be extracted by open pit mining. This depth coincides with the maximum depth of a Whittle optimised pit-shell, used for the purposes of the Wardrop Engineering mining options study. The pit-shell is illustrated in Figure 1. A cut-off grade of 2 g/t Au was established from the economic model derived from this pit-shell and the resource blocks measure 25m x 25m x 10m. SRK Mineral Resource Statement Classification Vein Tonnage Grade Metal * (Kt) (Au g/t) (Ag g/t) (kg Au) (kg Ag) Measured Arzu South 390 6.4 101 2,500 39,000 Indicated Arzu South 110 5.7 106 600 12,000 Indicated Arzu North 50 2.3 38 110 1,800 Inferred Arzu North 100 2.2 29 200 2,900 Inferred Banu 130 2.6 82 330 10,500 Inferred Derya 170 2.9 53 500 9,000 * Equivalent to 186,360 oz gold equivalent. The gold equivalent is calculated on the basis of a 50:1 price ratio between gold and silver (this price ratio fluctuates and is dependent on market conditions). SRK considers there to be relatively good exploration potential in the wider Kiziltepe project area. Several new targets will be the focus of additional drilling in the near future (Figure 2). An extensive resistivity / conductivity geophysics survey is also planned across the project area to help resolve several possible blind targets prior to drill-testing, in particular the 650m long area between Arzu South and Arzu North. The exceptionally high conversion of Inferred Mineral Resources to Indicated and Measured Mineral Resources at Arzu South demonstrates the robust nature of the geological model applied and provides greater confidence in the selection of veins for follow-up drilling in 2008 and 2009. Leapfrog Model In addition to the resource estimate, SRK has applied 'Leapfrog' grade shell visualisation software to the Arzu South drilling database to identify the potential continuity of mineralisation below the current open-pit model and to provide follow-up exploration targets. The Leapfrog model has further reinforced geological understanding of the vein system and the view that there is a consistent southeast plunge component to most of the high-grade shoots within the vein segments (Figure 3). In the southern part of the vein system it is also apparent that the high-grade shoots may step-out and continue beyond the southeastern-most drilling on the Arzu South vein system, where mineralised structures were intersected but with diminishing grade and width. The concentration of high-grade mineralisation in the southern portion of the Arzu South vein system highlights the significance of this area for potential further resource growth.

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 750m 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. Franco-Nevada Corporation 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, reverse circulation chips 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.
