Ariana Resources plc has told DirectorsTalk this morning about an increase and update of its JORC compliant Mineral Resource estimate for the Kiziltepe Project following its recent drilling programme in Turkey. Kiziltepe is part of the Red Rabbit Joint Venture with Proccea Construction Co. and will be 50% owned by Ariana once mine construction is completed in H2 2016. Highlights: -- Overall increase in Mineral Resource estimate of c. 44,500 oz Au and 886,000 oz Ag to a total of 195,200 oz Au and 3.15Moz Ag contained metal on four main veins, excluding existing resources on several subsidiary veins such as Kepez.* -- Substantial increase in tonnage (to c. 2.5Mt) with a corresponding reduction of grade (to c. 2.5 g/t Au and 40.3 g/t Ag) as a result of adoption of revised geological model. -- Large increase (approx. 45%) in volume of new Whittle-generated pit shells in comparison to designed pits, notably Arzu North and Derya. -- Whittle base case optimisation demonstrates a potential increase in mine life from c. 8 years to c. 10 years at a designed throughput rate of 150,000 tonnes per annum. Dr. Kerim Sener, Managing Director, commented: "Following the completion of an extensive review of our geological model and the addition of new drilling data, this result is a very pleasing update on our resource estimate for the Kiziltepe Mine. Importantly, the discovery cost of these additional ounces is approximately US$5 per ounce, which demonstrates the very cost-efficient exploration we are able to conduct on this project. The resource update, in addition to Whittle optimisation work, demonstrates the potential for Kiziltepe to provide for a mine life of about 10 years at the designed throughput rate of 150,000 tonnes per annum. This also excludes several subsidiary veins on which we have already established resources, which with further work may add further to mine life. With the enlarged resource and with expectations of further resource growth, we are now reviewing our options to potentially increase the mine throughput rate up to 200,000 tonnes per annum with our partners, Proccea. Meanwhile, construction at the mine is proceeding well, with delivery of the ball-mill to site occurring a few days ago." * All Mineral Resource figures in the announcement are quoted gross with respect to the Red Rabbit Joint Venture. Ariana will own 50% of the production from the JV when the Kiziltepe Mine is operational. Resource Estimate Following the completion of a 1,208m Reverse Circulation ("RC") drilling programme in December 2015 (see 31 January 2016 Announcement), geological consultants Odessa Resources Pty. Ltd. undertook a resource estimate for Kiziltepe. The recent RC drilling coupled with certain diamond drilling completed in late 2011 and early 2012, totalling 1,290m, was used in the new estimation. The new Kiziltepe JORC 2012 compliant Mineral Resource estimate has been defined by 213 drill holes and 125 rock-saw channels on 212 cross-sections with typically 10m section spacing (see JORC Table 1 below). Wireframes were constructed using sectional polylines defined by a cut-off of 0.5 g/t gold. Several lodes were created from the sectional interpretations, which are orientated NW and WNW and typically dip steeply at up to 85 degrees towards the northeast (Figure 1) comprising four main areas, Arzu South, Arzu North, Banu and Derya. Top cuts of 15 g/t Au and 200 g/t Ag were used and a variable bulk density ranging between 2.50 and 2.65 g/cm(3) were assigned to the appropriate solids and used for the resource estimation. Grade interpolation was by the Inverse Distance Squared ("ID2") method. The previous estimate, completed in 2013 by Tetra Tech, identified a JORC 2004 compliant Mineral Resource of 1,502,000 tonnes at 3.12g/t gold and 46.97g/t silver on four main veins (excluding separate estimates on subsidiary veins and alteration halo mineralisation), based on drilling completed until 2011. The addition of 16 diamond holes and 19 RC holes undertaken for infill and extension drilling at Kiziltepe completed since late 2011, in addition to corresponding modifications of the geological model, has increased the Mineral Resource on these four main veins to 2,436,315 tonnes at 2.49g/t gold + 40.27g/t silver and has confirmed the potential extension of the Arzu structure under cover between Arzu South and Arzu North. This estimate specifically excludes several subsidiary veins on which Inferred resources have previously been established (for an additional 18,555 oz Au equivalent), such as Kepez, Derya West, Aybor, Ceylan and Arzu Far North, in addition to a potential 28,230 oz Au equivalent, referred to as "Alteration Halo" in the Tetra Tech estimate. Further drilling, modelling and economic assessments will be required on these subsidiary veins and alteration halo mineralisation to determine their potential to be included as Ore Reserves. Table 1: Summary 2016 Kiziltepe JORC 2012 compliant Mineral Resource estimate, based on 125 diamond and 76 RC drill holes. This estimate excludes several subsidiary veins such as Kepez, which were a part of the previous resource estimate. Gold equivalent is the sum of the gold ounces and the gold equivalent ounces of silver based on a price ratio of 60:1. Reporting at a 1/g/t Au cut off, excluding Banu which is included in these figures at a 0.5 g/t Au cut-off. All figures are quoted gross with respect to the Red Rabbit Joint Venture.
