"We continue to be very encouraged by the results of the wide-spaced drilling program on the Korkan-Bigar target area, in particular the Bigar Hill area, where we have established a very broad footprint to mineralization in a relatively short period of time," said James Crombie, President and CEO of Avala. "We expect to commence reverse circulation drilling in August and will be focussing on establishing continuity of mineralization. Additionally, we will continue to drill test the multiple target areas within the 20 kilometer long sediment-hosted gold belt defined to date."
1. HIGHLIGHTS -- Wide-spaced 'step out' drilling (nominal 160 meter by 160 meter) on the Korkan-Bigar target area continues to intersect gold mineralization within the target stratigraphy, a sequence of strongly altered and decarbonatized conglomerates and sandstones with interbedded fine grained sandstone and clay-rich siltstones, marls and andesitic volcanics/volcaniclastics. -- Drilling of the Korkan-Bigar target area (Bigar Hill) returned the following strong gold intercepts (0.4g/t cut-off grade): ------------------------------------------------------------------------- Hole ID From (m) To (m) Interval (m) Au (g/t) Gram-meters ------------------------------------------------------------------------- ------------------------------------------------------------------------- BHDD011 118 147 29 1.97 57 BHDD016 29 66 37 1.37 51 BHDD017 136 142 6 7.37 44 BHDD017 194 208 14 3.05 43 BHDD020 6.2 39 32.8 2.04 67 BHDD021 165 178 13 3.18 41 BHDD023 22.5 34 11.5 1.82 21 BHDD023 122 143 21 1.59 33 ------------------------------------------------------------------------- -- Drilling of the Korkan-Bigar target area (Korkan) returned the following gold intercept (0.4g/t cut-off grade): ------------------------------------------------------------------------- Hole ID From (m) To (m) Interval (m) Au (g/t) Gram-meters ------------------------------------------------------------------------- ------------------------------------------------------------------------- KODD044 259 273 14 5.44 76 ------------------------------------------------------------------------- -- To date Avala has outlined gold mineralization at Korkan over an area of approximately 1,200 meters by 600 meters surrounding the original discovery hole (KODD001) and an area of 1,000 meters by 1,000 meters on the Bigar Hill target area (open in all directions). Kraku Pestar has been traced over 600 meters by 300 meters and is open to the north and south. -- Weighted averages of uncut grade and down hole intersection thickness per hole have been determined for the 160 meter by 160 meter spaced diamond drilling to date, based on a 5 meter minimum thickness and 5 meter maximum included waste and a range of gold cut off grades. Very encouraging mean grades and thicknesses have been returned. Multiple mineralized intercepts per hole are a common feature of the target areas, (as illustrated in Figure 3): ---------------------------------------------------------------------------- 0.4g/t Au Cut Off 1.0 g/t Au Cut Off ------------------------------------------------------------------- ------------------------------------------------------------------- Weighted Weighted Weighted Intersection Weighted Intersection Average Thickness Per Average Thickness Per Target No. of Grade Hole No. of Grade Hole Area Holes (g/t) (meters) Holes (g/t) (meters) ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- KORKAN 15 1.84 22 8 3.01 21 BIGAR HILL 14 1.52 32 12 2.29 20 KRAKU PESTAR 9 1.11 40 6 2.30 21 ---------------------------------------------------------------------------- (Note: Down hole intersections do not necessarily represent true thicknesses) -- Avala intends to continue the wide-spaced drilling program to test the prospective 'target stratigraphy' within an initial area of over 3.5 square kilometers in the Korkan-Bigar target area, in order to effectively outline the size of the newly defined sediment-hosted gold system. -- The combined Korkan-Bigar target area is over 10 kilometres long and 2.5 kilometers wide and represents part of the northern portion of the sediment-hosted gold belt. -- An initial selection of gold mineralized drill core intervals have been sent to SGS Cornwall for preliminary metallurgical test work; the program will focus on the preconcentration (flotation) characteristics of the gold mineralized clastic sediments. -- Avala currently has four diamond drill rigs operating on the Korkan- Bigar target area. Two diamond drill rigs have been allocated to the southern portion of the sediment-hosted gold belt on the Umka-Strnjak target area where scout drill holes are being drilled on nominal 320 meter by 320 meter centers within the target stratigraphy. -- A Reverse Circulation (RC) drill rig (GEMEX RC-500) is expected to be onsite and operational during August 2011. The RC rig is scheduled to undertake infill drilling at an initial 80 meter by 80 meter spacing within the mineralized 'footprints' currently being outlined by the 160 meter by 160 meter diamond drilling program. Further drill rigs are currently being sought. -- Additionally, Avala has submitted several exploration licence applications to the Serbian Ministry of Environment, Mining & Spatial Planning for areas that the Company believes are prospective for sediment-hosted gold style of mineralization within the Timok. Together with currently granted exploration licences, Avala believes that the overall strike length of the sediment-hosted belt could potentially increase from the currently defined 20 kilometers to approximately 50 kilometers. -- Please see the following link to view all Korkan-Bigar and Kraku Pestar drill holes located spatially in three dimensions: http://www.corebox.net/properties/potoj-cuka-gold-belt 2. GEOLOGY AND MINERALIZATION STYLE -- Sediment-hosted gold, located along the western margin of the Timok Magmatic Complex, represents a previously unrecognized style of gold mineralization within the Timok region. -- In the Korkan-Bigar target area, stratabound, fault-controlled breccia together with minor karst-infill breccia represent the styles of sediment-hosted gold mineralization recognized to date. -- Gold mineralization appears to be associated with fine-grained pyrite (sulfidation reaction) and a number of alteration styles including kaolinitization, decarbonatization of calcareous sedimentary rock adjacent to the gold mineralization and occasionally jasperoids. -- Gold mineralization is hosted within a favourable sedimentary package - the 'target stratigraphy' - which is underlain by Jurassic and Lower Cretaceous limestones and consists predominantly of calcareous sandstones and conglomerates which include an interbedded fine grained sandstone and clay-rich siltstone unit. -- The upper portion of the target stratigraphy consists of 'red' sandstones and volcanic-lithic clastics which are in turn overlain by calcareous marls and andesitic volcanics, which represent the youngest portion of the stratigraphy. -- To date gold mineralized intervals have been returned from all portions of the target stratigraphy, excluding, to a certain extent, the marl unit and the interbedded fine grained sandstone and clay-rich siltstone unit which have been only weakly mineralized; Avala believes that these units may be locally acting as an aquitard, or capping unit, to hydrothermal fluids. -- In general the target stratigraphy in the Korkan-Bigar target area appears to be gently dipping towards the east and may have been gently folded with a northwest axial plane. -- Figure 1 shows the location of the Korkan-Bigar and Kraku Pestar target areas within the currently defined 20 kilometer long sediment-hosted gold belt, defined in this image by anomalous gold soil geochemistry, together with their respective total metal contour plots superimposed. The significant potential of the belt can be clearly seen when the surface area of the 'footprints' of the currently drilled target areas are compared to the overall extent of the presently defined gold soil anomalies. 3. DRILLING AT KORKAN-BIGAR -- Bigar Hill: Avala is continuing the 'step out' drilling program at the Korkan-Bigar target area, on a nominal 160 meter by 160 meter spacing. See Table 1 for a summary of all intersections at various cut-off grades for the results of diamond drill holes BHDD008 to BHDD023. -- Figure 2 shows a gram-meter (intervals greater than 0.4g/t Au x thickness), total metal contour plot of all Korkan-Bigar drilling to date superimposed on mapped geology. -- Strong gold mineralization is hosted within polymict conglomerate and sandstone intervals which have been strongly decarbonatized with intense, sooty, fine grained pyrite matrix infill. Recent drilling has now also confirmed gold mineralization (BHDD014: 20m @ 1.65g/t Au (from 114m)) within the andesitic volcanics/volcaniclastics which were previously thought to be a poor host to gold. To date gold mineralization within the footwall Jurassic massive limestone at Korkan- Bigar has been of an overall low-moderate tenor and is generally associated with brecciation, either karst or brittle deformation. -- Additional drilling was completed within the Korkan target area and results have been returned for the following nineteen drill holes: KODD022 and KODD027 to KODD044. See Figure 2 & Table 2. -- Final assays have also been received from the Phase I wide-spaced diamond drill program on the Kraku Pestar target area (see AVZ press release Oct. 7th, 2010 for background information). See Figure 4 & Table 3. -- Multiple gold mineralized intercepts per hole are a common feature of the gold mineralization outlined to date in the Korkan, Bigar Hill and Kraku Pestar target areas. 4. DISCUSSION -- A major sediment-hosted gold belt bordering the western boundary of the Timok Magmatic Complex, identified by soil and trench samples, extends over 20 kilometers along strike and is up to 8 kilometers wide. -- The geology, geochemistry and available drill intersections suggest a strong similarity to the style of gold mineralization typified by the North Carlin Trend, Nevada, USA. -- The recognition that the majority of the significant trench and diamond drill intercepts returned to date occur within the same flat lying or shallow dipping sedimentary package has significant implications for the gold potential of the Korkan-Bigar target area and the entire sediment- hosted gold belt. -- The mineralized intersections detailed in Tables 1, 2 and 3 (for Bigar Hill, Korkan and Kraku Pestar respectively) have been compiled using a minimum 5 meter thickness and a maximum of 5 meters of included waste and a variety of lower cut off grades. Weighted mean gold grades and intersection thicknesses have been compiled for each area and are displayed in Table 4. Very encouraging grades and thicknesses have been returned. Multiple intercepts per hole are commonly encountered, particularly at Korkan and Bigar Hill.

To date some 246 density samples have been collected and measured from samples returning greater than 0.1g/t Au and 85 density measurements from samples grading over 0.4g/t Au within the sediment-hosted gold belt. Density data from the three target areas return very similar average bulk densities at 2.63 tonnes per cubic meter, as summarised in Table 5 (note that there is currently a backlog of density samples from the Bigar Hill drilling).

SAMPLING AND ANALYSIS
The majority of soil samples have been assayed at the ALS Chemex laboratory, Perth, Australia. More recent programs have been assayed at the SGS managed laboratory at Chelopech in Bulgaria using a combination of ICP-OES and ICP-MS whereas gold has been assayed by low level detection fire assay method with an AAS finish. The Company has established a laboratory facility at Bor, Eastern Serbia which is independently managed by SGS. Trench samples were prepared at the laboratory facility at Bor and the samples have been assayed at the SGS managed laboratory at Chelopech in Bulgaria or the laboratory facility at Bor. Diamond drill core has been prepared at the laboratory facility at Bor and assayed at either the SGS managed laboratory at Chelopech in Bulgaria or the assay laboratory at Bor. A one metre sampling interval has been used where possible for the Sediment-Hosted Gold project diamond drilling program. Half core is routinely submitted to the laboratory for analysis. Following Avala standard quality assurance procedures, a full suite of field and laboratory duplicates and replicates along with internationally accredited standards and blanks, have been submitted with each batch of samples.
Trench sampling was carried out as channels in the wall just above the trench floor on 2m intervals. Except where extensive soil cover is encountered, trenches were sampled in their entirety. The samples were routinely weighed prior to final bagging to maintain an even sample size and to avoid sampling bias in harder rock types. An average channel sample weight was maintained at 3kg/m, which produces a consistent sample weight approximating half HQ core samples. Field duplicate samples were taken every 20 samples and known standards were inserted into the sample stream after every 20th sample. A geological and structural log was completed as for diamond drilling. All data collected in the field was routinely entered into geology and structural geology spread sheets using Field Marshal software for subsequent entry to an acQuire database and validation.
