LONGUEUIL, QUEBEC -- (Marketwire) -- 01/09/13 -- Dunav Resources Ltd. (TSX VENTURE: DNV) (the "Company" or "Dunav") is pleased to present an exploration update on its 100% held Tulare Copper-Gold Porphyry Project located in Southern Serbia.
1. HIGHLIGHTS-- Late in the 2012 field season, four very wide-spaced diamond drill holes were completed on the Bakrenjaca carbonate-base metal gold epithermal system which is located 3 km south from the Kiseljak copper-gold porphyry deposit. All four drill holes intersected epithermal-style mineralization.-- Results have now been returned from this initial 'scout' drilling program which was designed to follow-up on encouraging surface trench results. The area of mapped alteration and epithermal mineralization covers an area of approximately 1.5 km x 1 km and significant intersections are listed below, calculated using a 0.4 g/t AuEq cut-off grade:---------------------------------------------------------------------------- From To Interval Au Ag Cu Pb Zn AuEqHole ID (m) (m) (m) (g/t) (g/t) (%) (%) (%) (g/t)----------------------------------------------------------------------------BKDD001 36 40 4 0.48 5.53 0.03 0.46 0.38 0.96BKDD001 64 68 4 0.11 5.85 0.11 0.07 0.05 0.43BKDD001 100 111 11 5.13 346 1.19 2.36 1.86 14.5BKDD001 116 127 11 0.37 7.82 0.08 0.23 0.88 1.09BKDD002 9 16 7 0.48 1.34 0.00 0.07 0.86 0.89BKDD002 28 31 3 0.50 0.88 0.00 0.05 0.12 0.59BKDD002 35 42 7 0.84 1.10 0.01 0.04 0.10 0.93BKDD002 49 79 30 0.36 1.70 0.01 0.12 0.28 0.58BKDD002 132 137 5 0.07 1.10 0.03 0.18 0.83 0.55GUDD001 80 85 5 0.14 4.14 0.04 0.24 0.34 0.52GUDD001 95 98 3 0.19 5.97 0.01 0.56 0.14 0.60GUDD001 156 160 4 0.23 6.70 0.01 0.20 0.12 0.49GUDD001 170 173 3 0.11 3.77 0.05 0.18 0.32 0.45GUDD001 178 182 4 0.15 7.58 0.05 0.57 0.47 0.78GUDD001 231 235 4 0.49 6.82 1.12 0.05 0.01 2.41GUDD001 296 317 21 0.11 4.91 0.07 0.85 1.13 1.12GUDD001 323 326 3 0.01 2.87 0.07 0.78 2.40 1.48GUDD001 447 452 5 0.03 0.76 0.05 0.27 0.46 0.42GUDD002 11 15 4 0.20 2.10 0.00 0.22 0.33 0.46GUDD002 35 39 4 1.03 13.3 0.05 0.84 1.45 2.28GUDD002 47 51 4 0.10 8.77 0.06 0.27 0.22 0.55GUDD002 141 144 3 0.10 1.79 0.00 0.34 1.60 0.93---------------------------------------------------------------------------- - 0.4 g/t AuEq cut-off ($1,500/oz.

Dunav controls 100% of this newly identified porphyry cluster, located within the Lece Volcanic Complex.-- G Mining Services Inc. (Montreal) have been contracted to manage the Preliminary Economic Assessment (PEA) of the Tulare Copper-Gold Porphyry Project.2. TRENCHING AT BAKRENJACA-- First pass exploration trenching was completed at Bakrenjaca based on the detailed soil geochemistry (nominal 100 meter by 25 meter grid) which had previously outlined a strongly anomalous Au-Ag-Cu-Pb-Zn zone over an approximate area of 1.5 km by 1 km. Individual soil samples returned up to 5.37 g/t Au, 39.3 g/t Ag, 0.58% Cu, 1.35% Pb and 0.62% Zn (refer to Figure 4).-- It should be noted that the initial first pass trenching program was largely predicated on areas where access was readily available; all significant intersections are listed below, calculated using a 0.4 g/t AuEq cut-off grade:---------------------------------------------------------------------------- From To Interval Au Ag Cu Pb Zn AuEqTrench ID (m) (m) (m) (g/t) (g/t) (%) (%) (%) (g/t)----------------------------------------------------------------------------BKTR003 0 3 3 0.38 6.50 0.01 0.41 0.20 0.75BKTR003 16 19 3 0.12 3.80 0.01 0.30 0.30 0.44BKTR005 4 8 4 0.04 0.63 0.00 0.15 1.02 0.54BKTR006 6 15 9 0.20 1.13 0.00 0.17 0.26 0.40BKTR007 6 19 13 0.23 1.11 0.01 0.33 0.76 0.71BKTR011 30 46 16 0.53 1.06 0.00 0.24 0.11 0.69BKTR012 14 23 9 0.32 0.96 0.02 0.17 0.79 0.76BKTR013 1 6 5 0.89 10.1 0.11 0.54 0.11 1.50BKTR014 0 8 8 0.04 0.75 0.97 0.09 0.13 1.69BKTR015 1 23 22 0.39 8.02 0.08 0.40 0.68 1.10BKTR016 56 71 15 0.44 2.85 0.01 0.19 0.05 0.61BKTR018 20 36 16 0.16 14.3 0.29 0.36 0.17 1.08BKTR019 0 46 46 0.48 16.4 0.21 0.28 0.69 1.50BKTR021 0 15 15 0.25 5.03 0.11 0.67 0.04 0.80BKTR021 21 27 6 0.11 1.67 0.04 0.52 0.03 0.42BKTR021 34 41 7 0.57 4.29 0.06 0.81 0.06 1.09BKTR021 50 55 5 0.55 8.50 0.06 0.70 0.01 1.07BKTR021 80 84 4 0.18 4.08 0.05 0.29 0.01 0.45BKTR022 3 26 23 1.03 11.6 0.31 2.65 0.37 2.96BKTR023 4 15 11 0.18 2.72 0.08 0.47 0.09 0.58----------------------------------------------------------------------------- 0.4 g/t AuEq cut-off ($1,500/oz.

These trench sampling results are expected to be available during Q1 2013.-- Refer to Table 2 for a summary of all exploration trench intersections at various AuEq cut-off grades for all Bakrenjaca trenches to date; BKTR001 to BKTR024.-- Refer to Figure 2 for the location of all trenching and diamond drilling completed to date within the Bakrenjaca mineralized 'footprint' and to Figure 3 for a representative cross-section through the Bakrenjaca target area.3. DRILLING AT BAKRENJACA-- Four diamond drill holes have been completed at Bakrenjaca for a total of 1,051.6 meters.-- All four drill holes intersected epithermal-style mineralization, which, given the initial wide-spaced 'scout' drill hole spacing, may be viewed as very encouraging.-- In general, the level of surface oxidation is low with sulfide mineralization commencing within 10 meters of the surface.-- Drill hole GUDD001 (498.7 m) was the deepest hole drilled into the target area and it is of particular interest that epithermal-style mineralization was intersected throughout the drill hole, which indicates that there is epithermal mineralization occurring over a minimum 400 meters vertical extent within the Bakrenjaca target area.-- Refer to Figure 2 for the location of all trenching and diamond drilling completed to date within the Bakrenjaca mineralized 'footprint' and to Figure 3 for a representative cross-section through the Bakrenjaca target area.-- Refer to Table 1 for a summary of all exploration diamond drill hole intersections at various AuEq cut-off grades for all Bakrenjaca drill holes to date (BKDD001 to BKDD002 and GUDD001 to GUDD002).4. GEOLOGY AND MINERALIZATION STYLE-- The Bakrenjaca carbonate-base metal gold epithermal vein system is located approximately 3 km south of the Kiseljak deposit and comprises east-west trending corridors of sheeted to stockwork manganese carbonate +/- quartz gold-silver-base metal veins hosted within argillic (sericite-illite-smectite) altered andesitic volcanics, volcaniclastics and sediments. Mapped zones of mineralization at surface range from less than one meter to greater than thirty meters width.-- Based on this initial drilling program Dunav has noted two differing styles of epithermal mineralization: -- 'Hangingwall-style' mineralization associated with manganese carbonate (rhodochrosite) +/- quartz/chalcedony veining within the volcano-sedimentary package which contains Au-Ag-Pb-Zn (sphalerite, galena and pyrite) mineralization and display typical epithermal textures such as colloform-crustiform banding. -- 'Footwall-style' mineralization as evidenced by BKDD001 (100-111m) which has high grade Au-Ag-Cu-Pb-Zn mineralization and is located at the low angle contact between the metamorphic basement (gneiss) and the overlying volcano-sedimentary package. Carbonate replacement textures (bladed quartz) indicative of boiling are evident within this high grade zone.-- See Figure 3 for a representative cross-section through the Bakrenjaca target area.5. DISCUSSION-- Carbonate-base metal-gold epithermal deposits represent some of the most prolific gold producers in the SW Pacific rim (e.g. Victoria Veins-Far Southeast Lepanto, Philippines); they have also been recognized in the Andes of South America, North America and in the Carpathian Mountains (Western Tethyan) of Eastern Europe.-- The Tulare Copper-Gold Porphyry Project is located in southern Serbia, approximately 230 km from Belgrade and 70 km from the regional centre of Nis. Access to the project is excellent via sealed roads. A rail heading is available some 45 km from the project area at the city of Leskovac, or 30 km to the northwest at the town of Kursumlija. Reticulated power passes close to the project area.-- The Tulare Copper-Gold Porphyry Project area lies within the Lece Volcanic Complex of southern Serbia; the second largest magmatic complex in Serbia after the Timok Magmatic Complex.-- Preliminary metallurgical test work on diamond drill core samples from Bakrenjaca will be selected and dispatched during Q1 2013.-- Dunav plans to commence a detailed drill assessment of the Bakrenjaca target area during the first half of 2013 in order to determine the potential mineralized footprint of that epithermal system.6.
