Ltd. PREVIOUS INVESTIGATIONS: Opening of quarry faces in several spots, core drilling in limited quantities and depth LOCALIZATION: The site is located at about 3 hours driving by car from Sivas, through highway and mountain roads, at about 2.500 m a.s.l. Site location from a 1:800.000 scale road map of Turkey Benetti Macchine S.p.A. Via Provinciale Nazzano, 20 – 54033 Carrara, Italy P.O.

Color and texture is seen to change according to the inclined bedding. Presence of highly fractured zones, micro-cracks, and of spots with high concentration of white calcite veins Massive portion of the limestone formation Contact of the limestone formation with reddish shale 4 Benetti Macchine S.p.A. 5 Via Provinciale Nazzano, 20 – 54033 Carrara, Italy P.O.

Beige marble and “breccias” could reach higher interest in the world market than grey variety. For its relatively low commercial value with respect to other stone varieties, the grey limestone could reach high interest in the market if produced in large quantities.

The selection and the classification by variety of the blocks extracted from this area are indispensable for both the marketing and for the processing purposes. Selection of blocks according to the limestone variety found Benetti Macchine S.p.A. Via Provinciale Nazzano, 20 – 54033 Carrara, Italy P.O.

Prospecting and exploration on a detailed topographic map as a basis 1.1 - Surface sampling on 50 m spacing grid basis all over the area, to check color and texture on the surface 1.2 - Core drilling 30-40 m in depth on most interesting spots, based on results of 1.1 1.3 – Geologic mapping, geologic cross-section and projections of results of 1.1 and 1.2 1.4 – Deposit assessment and estimate of reserves of each stone variety found 7 Benetti Macchine S.p.A.

Market investigation of most important stone varieties found; hypotheses on F.O.B sale price of blocks of each stone variety; if sale price results to be relatively low, large quantities of blocks should be produced to compensate the operational cost, and the transport cost of the blocks to F.O.B. 3. Pre-feasibility study: set target production capacity; select appropriate quarrying methods and technologies (i.e. combination of chain saw and diamond wire cutting); select and evaluate equipment, service and facilities; set development planning and production target; cost-benefit analysis 8 Benetti Macchine S.p.A.
