MINED TONNAGE AND GRADE RECONCILIATION ADDITIONAL CAPEX AND OPEX INFORMATION
Mined Tonnage and Grade Reconciliation
Korab Resources (“ Korab ” or “ Company ”) is pleased to advise that grade reconciliation work completed on the mineral resource mined at the Company’s Bobrikovo open pit gold mine in Ukraine continues to show that the actual overall gold grades of rock mined exceed gold grades predicted by the block model used to estimate the resource in accordance with JORC code.
The deposit contains approximately 2 Mln ounces of gold estimated in accordance with JORC code (see Appendix A for details). Mineral resource is currently undergoing an upgrade.
Similar to the grade reconciliation reported in October 2012, the most recent reconciliation work conducted by the Company on the material mined from open pit in late 2012 and early 2013 continues to show that the mined grade of the low grade rock is approximately 2.60 g/t Au which is 60% higher than the 1.6 g/t Au grade predicted by the block model.
This variation is due to the extremely conservative model adopted for the estimation of the mineral resource (released to the market on 8 October 2012). The model used ID4 (inverse distance to the power of 4) and consequently generated an extremely conservative resource estimate by not allowing smoothing of the data. As a result, this would have underestimated the total ounces contained when compared to a model using a lower power interpolation method.
Grade reconciliation work also confirmed the mined grade of high grade rock is approximately 4.8 g/t Au which is consistent with gold grades predicted by the block model.
The gold grade reconciliation work covered 50,000 tonnes of the high grade rock and 285,000 tonnes of the lower grade rock mined by Korab. The Company has also mined approximately 700,000 tonnes of very low grade rock assaying under 0.8 g/t Au (averaging 0.5 g/t Au) which is currently stockpiled as waste but which may be considered for treatment in the future.
The tonnage and grade of oxide ore which has been mined by Korab and stockpiled on site is as follows:

Korab advised in February that it is considering extraction of gold from the ore stockpiled on site using a low cost second hand gravity processing plan. The Company advised in early March that it has commenced construction of the gravity processing plant and the ancillary infrastructure including lab, mechanical workshops and the administration building at the mine site. At the same time, Korab released exceptionally positive results of the evaluation of the Stage 1 of economic development of the project which intends to process the ore mined and stockpiled by Korab using a second hand simple gravity circuit.

Oxide ore from Bobrikovo is amenable to low cost gravity processing using a simple low cost circuit designed to produce concentrate containing gold, silver, and base metals. Bobrikovo oxide ore is very soft and brittle, thus requiring very little energy to grind it to suitable grind size. Additional benefit of the oxide ore is that its gold particles are relatively large and occur as free grains. This makes the oxide ore from Bobrikovo suitable for gold and silver extraction without the use of chemicals and at relatively coarse grind size. It is because of the excellent grindability and metallurgy of this heavily weathered ore that the CAPEX and the OPEX of Stage 1 development can be exceptionally low.
The operating profit from 12 month of production is expected to be around $11.5 million before tax. Production is fully permitted, however the commencement of the production of concentrate will depend on the timing of the completion of the gravity processing plant. The CAPEX is estimated at $700,000. The processing cost of ore to concentrate is $295/ounce. The selling costs and the discount to the spot gold price upon sale of the concentrate to refinery is approximately 15% of the gold price.
The input variables used to generate the targeted operating profit, production profile and operating costs are as follows:

Project Description
The deposit is located in eastern Ukraine, within Nagolny Ridge, a part of a large intra‐ continental geological structure that extends from southern Europe east to Central Asia. This structure hosts several world‐class gold mining operations including 170 million ounces Muruntau gold deposit as well as Vysokovoltnoe, and Bakirchic gold deposits. The style of mineralisation at Bobrikovo is similar to 170 million ounces Muruntau deposit in Uzbekistan and to 57 million ounces of gold Sukhoi Log deposit in Russia.
The deposit occurs on the intersection of deep fault zones. Mineralisation is controlled by NW‐ NNW trending anticline hinge, and occurs as concordant and discordant quartz‐carbonate tension veins and stockworks. Mineralised zone is 3 km long and 1 km wide. Exploratory drilling and seismic surveys indicate that mineralised rocks continue to at least 3 km depth. Whole rock geochemistry indicates that the mineralisation is mantle derived. Host rocks of the Nagolny Kryazh comprise two structural stages: the lower, Precambrian, and the upper, Phanerozoic. The lower structure comprises deformed sequence of gneisses and crystalline schists. Precambrian basement is overlapped by 3 km‐thick sedimentary rock sequence.
