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.

About the Kiziltepe prospect
The Kiziltepe prospect is located within a ten-year renewable
operating licence that forms part of the Company's 100% owned
Sindirgi gold project in Balikesir Province, western Turkey.
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.
