Jorc Compliant Resource and Scoping Study Report

4 April 2011 AIM / PLUS Markets: AAU JORC COMPLIANT RESOURCE & SCOPING STUDY REPORT Ariana Resources plc ("Ariana" or "the Company"), the gold exploration and development company focused on Turkey, is pleased to announce that its consultants Wardrop, a Tetra Tech Company ("Wardrop") have finalised a resource estimate and scoping study report in accordance with Joint Ore Reserves Committee 2004 guidelines ("JORC").  This has been finalised as a part and in advance of completing the Company's ongoing Pre-feasibility ("PFS") work on the Kiziltepe Sector of its Red Rabbit Joint Venture. Highlights: * Combined resource in preliminary optimised pits is approximately 1 million tonnes at an average grade of 3.6 g/t Au and 41.6 g/t Ag* * Output expected at a rate of 150,000 tonnes ore per annum, corresponding to an average production of approximately 20,000 oz/year of gold equivalent, over a mine life of 6.9 years * Financial model at a gold price of US$1350/oz and a silver price of US$20/oz provides an NPV (8% discount) of US$56.2 million and IRR of 75.9%, with payback secured in 1.2 years * Expected capital cost estimated at US$25.1 million * Cash costs are in the region of US$441 to US$472 per ounce across the financial model range. Dr. Kerim Sener, Managing Director, commented: "The completion of this report is an important part of our ongoing work programmes at Kiziltepe.  The JORC resource estimate is now provided in parallel with the results of our scoping study, to better define the direction being taken by the Company on this project.  We have demonstrated the economic potential of the project using base case gold and silver prices that may now be considered conservative.  The pit optimisation currently being considered for the PFS will inevitably be using higher base case metal prices (approximately US$1,100/oz for gold).  We have now demonstrated that there is little downside to this project and we are fully engaged with our partners, Proccea and consulting teams to ensure we remain on track with the feasibility and environmental studies." Scoping Study Following on from the resource estimate announced on the 28th October 2010, and while the Pre-feasibility Study ("PFS") remains underway, the Company wished to complete the documentation of its resource estimate and to update its February 2010 scoping study with the most recent resource figures.  For the purpose of the PFS, the Company is continuing to refine the economic parameters utilised for the purpose of the scoping study, but the figures provided here provide broad indication of the economic merits of the project. * All resource figures contained in this announcement are reported as gross with respect to the Red Rabbit Joint Venture.  Ariana currently owns 89% of the Joint Venture and remains the operator of this project. Open-pit Resources The mineral resource estimate announced on the 28th October 2010, remains unchanged (Table 1).  However Whittle Pit Optimisation Software has been run on this resource to determine that part of the total resource that could be extracted economically.  The combined resource within the preliminary selected pit shapes, including the Arzu South, Arzu North, Derya, Banu and Kepez pits, is estimated at 1,034,600 t at an average of 3.6 g/t Au and 41.6 g/t Ag.  Table 2 lists the selected pit resource by mineralised zone; the cut-off grade is estimated at 1.3 g/t Au based on a gold metal price of US$800/oz.  For this base case only resource blocks of Measured and Indicated category are used.  The listed tonnes and associated grades in Table 2 represent the selected Whittle pit shape derived from the Whittle Pit Optimisation Software results.  Mineral reserves are not estimated at scoping level.

Production Schedule The mine will be based on one central pit located at Arzu South with satellite pits at Arzu North, Banu, Derya and Kepez.  The size of the selected pits (excluding Kepez) is shown in Table 3, which provide an average strip ratio of 11:1.  The mine will target production of 150,000 tonnes per year of ore over a mine life of 6.9 years, operating for six days a week.  High grade ore of 4.7 g/t Au and 50.9 g/t Ag will be mined in the first three years of operation, with progressively lower grade ore being mined in the following three years.  The lowest grade stockpile ore of 2.1 g/t Au and 28.0 g/t Ag will provide the feed for the final 12 months of plant operation.

The estimated metallurgical recoveries are 88% for gold and 78% for silver based on test work undertaken in 2010.  These metallurgical recoveries correspond to the combined Kiziltepe selected pit resource head grades.  The estimated capital cost of the metallurgical plant is US$11.4 million. Financial Model An economic evaluation of the Kiziltepe Project was prepared based on a pre-tax financial model of a 6.9 year mine life and 1,034,600 tonne selected pit resource.  The pre-tax financial model was established on a 100% equity basis, excluding debt financing and loan interest charges on a total capital expenditure estimate of US$25.1 million.  The financial outcomes have been tabulated for NPV, IRR and Payback of Capital.  Discount rates of 8% and 10% were applied to all cases identified by metal price scenario.  Wardrop's base case prices for this analysis were as follows: * Gold -  US$800/oz. * Silver -  US$14/oz. The use of the US$800/oz Au for the pit optimisation study was to maintain continuity with the previous internal study and with the resource estimate as announced in October 2010.  Sensitivity analyses on the financial models were carried out to evaluate the project economics with plus or minus (+/-) 10%, US$973/oz and US$1,350/oz Au metal prices (Table 4). The US$973/oz Au price is used as a forecast long-term price obtained from the Energy and Metals Consensus Forecast (EMCF), at November 2010.  A 'current' price of US$1,350/oz Au is also included, which provides a view on the present worth of the project.  It is important to note that the project is now the subject of a Pre-Feasibility Study (PFS) and the base case price for gold will be US$1,058/oz.

About Ariana Resources Ariana is an exploration and development company focused on epithermal gold- silver and porphyry copper-gold deposits in Turkey.  The Company is developing a portfolio of prospective licences selected on the basis of its in-house geological and remote-sensing database, on its own in western Turkey and in Joint Venture with European Goldfields Limited in north-eastern Turkey.  European Goldfields owns 51% of this joint venture and, as the operator, is fully funding all exploration work on the JV properties until delivery of a feasibility study. The Company's flagship assets are its Sindirgi and Tavsan gold projects which form the Red Rabbit Gold Project.  Both contain a series of prospects, within two prolific mineralised districts in the Western Anatolian Volcanic and Extensional (WAVE) Province in western Turkey.  This Province hosts the largest operating gold mines in Turkey and remains highly prospective for new porphyry and epithermal deposits.  These core projects, which are separated by a distance of 75km, are presently being assessed as to their economic merits and now form part of a Joint Venture with Proccea Construction Co.  The total resource inventory of the Company stands at 448,000 ounces of gold equivalent. Ariana also has a strategic investment in Tigris Resources Limited (www.tigrisresources.com), a private Jersey-based exploration company, which is focused on the exploration of copper and gold deposits in southeastern Turkey.  Ariana retains 15% of Tigris Resources Limited.(I don't think "retains" is the right wording here - "holds" might be better.) Loeb Aron & Company Ltd. and Alexander David Securities Limited are joint brokers to the Company and Beaumont Cornish Limited is the Company's Nominated Adviser.

Glossary of Technical Terms "Au" the chemical symbol for gold; "cut-off grade" The lowest grade, or quality, of mineralised material that qualifies as economically mineable and available in a given deposit. May be defined on the basis of economic evaluation, or on physical or chemical attributes that define an acceptable product specification; "g/t" grammes per tonne; "low-sulphidation" a style of gold mineralisation which is typically found distal to volcanic centres and is characterised by adularia-sericite alteration and quartz veins; "Indicated resource" a part of a mineral resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. The locations are too widely or inappropriately spaced to confirm geological and/or grade continuity but are spaced closely enough for continuity to be assumed; "Inferred resource" a part of a mineral resource for which tonnage, grade and mineral content can be estimated with a low level of confidence. It is inferred from geological evidence and has assumed, but not verified, geological and/or grade continuity. It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that may be limited or of uncertain quality and reliability; "Inverse Distance Squared" a conventional mathematical method used to calculate mineral resources.  Near sample points provide a greater weighting than samples further away for any given resource block; "JORC" the Joint Ore Reserves Committee; "m"Metres; "Measured resource" a part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a high level of confidence.  It is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.  The locations are spaced closely enough to confirm geological and grade continuity; "Nearest Neighbour" a methodology used to derive the value of an attribute from surrounding sample data on the basis of point-to-point proximity; "Ordinary Kriging" is a geostatistical approach to resource estimation.  Instead of weighting nearby data points by some power of their inverted distance, OK relies on the spatial correlation structure of the data to determine the weighting values.  This is a more rigorous approach to modelling, as correlation between data points determines the estimated value at an unsampled point; "oz" Ounces; "porphyry" an igneous rock with larger crystals contained within a matrix of much smaller crystals; "stockwork" a mineral deposit in the form of a branching network of small irregular veins; "top cut" the maximum gold content for samples used to calculate an average gold content for a resource; "variographic" the use of semi-variograms (a mathematical technique) as part of the geostatistical methodology used to derive resource estimates; "Whittle" computer software that uses the Lerch-Grossman algorithm, which is a 3-D algorithm that can be applied to the optimisation of open-pit mine designs.  The purpose of optimisation is to produce the most cost effective and most profitable open-pit design from a resource block model.
