LONGUEUIL, QUEBEC -- (Marketwire) -- 02/25/13 -- Dunav Resources Ltd. (TSX VENTURE: DNV) (the "Company" or "Dunav") is pleased to present an exploration update on its 100%-held Degrmen Copper-Gold Porphyry Project located in Southern Serbia.
1. HIGHLIGHTS-- Late in the 2012 field season, an initial exploration trenching program was completed on the Degrmen copper-gold porphyry target which is located approximately 20 kilometers northwest of Dunav's Tulare Copper- Gold Porphyry Project.-- Results have now been returned from this trenching program which was designed to follow-up on an encouraging gold soil geochemical anomaly that extends for approximately 1.2 km by 0.3 km and sits within a larger area of mapped hydrothermal alteration, which covers an area of approximately 3 km x 2 km.

EXPLORATION AT DEGRMEN-- Dunav was granted the Degrmen exploration licence during Q2 2012 after applying to the Serbian Ministry of Natural Resources, Mining & Spatial Planning. Dunav has 100% control of the Degrmen exploration licence.-- Previous historic geological mapping by the Serbian State had identified a large zone of hydrothermal alteration, approximately 3km by 2km, within andesitic volcanics and volcaniclastics of the Lece Magmatic Complex.-- During the period 1984 to 1987, the Serbian State completed a twelve- hole diamond drilling program within the large alteration zone; all drill holes were drilled vertically to an average depth of 195 meters.-- Following the acquisition of the licence Dunav has completed the following exploration activities: -- Detailed ground magnetic survey over the large alteration zone on a nominal 200 meter line spacing. -- Detailed soil sampling program on a nominal 100 meter by 100 meter grid spacing. -- First pass geological mapping together with rock chip sampling. -- First pass trenching program.-- Dunav plans to commence an initial, wide-spaced diamond drilling program during Q2 2013, to determine the economic potential of the copper-gold porphyry system outlined to date.3. TRENCHING AT DEGRMEN-- Exploration trenching was completed at Degrmen based on the detailed soil geochemistry (nominal 100 meter by 100 meter grid spacing) which had previously outlined a strongly anomalous gold zone over an approximate area of 1.2 km by 0.3 km.-- It should be noted that the initial trenching program was largely predicated on areas where access was readily available. All significant intersections are listed in Table 1, calculated using various CuEq cut- off grades.-- Refer to Figure 3 for the location of all trenching completed to date within the Degrmen copper-gold porphyry-style mineralized 'footprint'.4. GEOLOGY AND MINERALIZATION STYLE-- The Degrmen copper-gold porphyry system appears to represent a typical, high-level, calc-alkaline, copper-gold porphyry-style of mineralization. The overall morphology of the diorite porphyry intrusive stock(s) is not known at this stage, however it is likely that they will form subvertical to gently inclined 'pipes' which have intruded into the andesitic volcanics and volcaniclastics that dominate the geology within the Degrmen exploration licence.-- The porphyry-style mineralization occurs as stockwork and disseminated zones; typical potassic alteration is associated with quartz- chalcopyrite-magnetite veining together with secondary biotite alteration. Later stage pyrite, with lesser quartz-chalcopyrite- magnetite veining, representing phyllic alteration, has also been recognized from mapping, within and proximal to the currently defined zone of potassic alteration.-- The Degrmen diorite porphyry, as defined by geological mapping and gold in soil geochemistry, currently measures some 1,200 meters by 300 meters where it is exposed at surface.-- See Figure 2 for an interpretive geological and alteration map of the Degrmen copper-gold porphyry target area and Figure 4 for an example of mineralized diorite porphyry from the currently defined zone of potassic alteration.5. DISCUSSION-- The Degrmen Copper-Gold Porphyry Project is located in southern Serbia, approximately 220 km from Belgrade and 96 km by road from the regional centre of Nis. Access to the area is excellent, via sealed roads, together with a well-developed secondary road network within the project area. The rail line is located approximately 3 km west from the project area and reticulated power, similarly, passes close to the project area.-- Historic exploration by the Serbian State (pre-1990) had outlined a large 3km by 2km hydrothermal alteration within the Degrmen exploration license area. Dunav has confirmed the size of the alteration system with ground magnetic, soil geochemical and geological mapping programs. Importantly, Dunav has defined a zone of potassic alteration associated with quartz-chalcopyrite-magnetite stockwork veining that extends over a currently defined area of 1,200 meters by 300 meters.-- For comparative purposes it should be noted that the Kiseljak copper- gold porphyry deposit was initially outlined at surface by trenching and soil geochemical programs together with geological mapping, over an area of 800 meters by 300 meters.-- The Degrmen Copper-Gold Porphyry Project area lies within the Lece Magmatic Complex of southern Serbia; the second largest magmatic complex in Serbia after the Timok Magmatic Complex.6.
