Avala Resources Completes the Initial Bigar Hill Resource Definition Drilling Program, Serbia

LONGUEUIL, QUEBEC--(Marketwire - Feb. 6, 2012) - Avala Resources Ltd. (TSX VENTURE:AVZ) (the "Company" or "Avala") is pleased to present an update on progress and drill results from the Korkan-Bigar trend, part of the sediment-hosted gold belt within the Cretaceous magmatic arc bordering the Timok Magmatic Complex ("TMC") in Eastern Serbia.

"The initial phase of resource definition drilling at Bigar Hill has now been completed and the drill hole database has been delivered to the independent consultants, in order to complete an initial resource estimate and a technical report compliant with Canadian National Instrument 43-101. Results to date indicate the existence of a very large area of mineralization and potentially substantial gold resource at Bigar Hill", said James Crombie, President and CEO of Avala. "Resource definition drilling has now commenced on the Korkan and Kraku Pestar target areas with the objective of completing the programs by the end of Q2, 2012. Concurrently we are advancing our other recently discovered target areas which are located in close proximity to the resource definition drilling areas"

  1. HIGHLIGHTS
  • The recently completed Bigar Hill resource definition program was focused on establishing continuity of mineralization. The drilling program has used a nominal 80 meter by 80 meter grid spacing, together with a subset of the target area at a nominal 40 meter by 40 meter grid spacing. The drill holes are located within the Bigar Hill mineralized 'footprint' that was outlined by Avala during the earlier, wide-spaced, 160 meter by 160 meter diamond drilling program, which started in February, 2011.
  • Recently complete resource definition reverse circulation (RC) drilling at Bigar Hill has returned the following strong to moderate gold intercepts (0.4g/t cut-off grade):

(*) Denotes a nominal 40 meter by 40 meter infill drill hole.
  • 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 (open to the east and north-east) 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 south.
  • Resource definition drilling has commenced on the Korkan target area.
  • Exploration drilling continues to test additional target areas, located in close proximity to the Korkan and Bigar Hill mineralized 'footprints'.
  • Avala intends to continue the wide-spaced drilling program, concomitant with the resource definition program, in order to continue to test the prospective 'target stratigraphy' within the Korkan-Bigar trend. The key aim of this aspect of Avala's exploration program is to effectively outline the size of the newly defined sediment-hosted gold system.
  • The combined Korkan-Bigar trend is over 10 kilometers long and 2.5 kilometers wide and represents only a small part of the northern portion of the sediment-hosted gold belt, as displayed in Figure 1.
  • Avala currently has eight diamond drill rigs and two RC drill rigs operating on the Korkan-Bigar portion of the sediment-hosted gold belt.
  1. 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.
  • Within the Korkan-Bigar trend, 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, silicification.
  • 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 clastic sediments, which are in turn, overlain by calcareous marls, andesitic volcanic and volcaniclastic rocks, representing the youngest portion of the target stratigraphy. The andesitic volcanic and volcaniclastics are part of the Timok Magmatic Complex.
  • Figure 1 shows the location of the Korkan-Bigar trend and the Kraku Pestar target area within the greater sediment-hosted gold belt, as defined in this image by mapped 'target stratigraphy'. Figure 1 also shows anomalous gold soil geochemistry, on which the total metal contour plots based on drill intersections are superimposed. The significant potential of the belt can be clearly seen when the surface area of the mineralized 'footprints' of the currently drilled target areas within the Korkan-Bigar trend are compared to the overall extent of the presently defined gold soil anomalies.
  1. DRILLING AT KORKAN-BIGAR
  • Resource Definition Drilling (Bigar Hill): Avala commenced RC drilling at Bigar Hill on the 18th August, 2011. Drilling was completed on the 23rd December, 2011 for a total of 44,114.6 meters (17,456.6 meters of diamond drilling and 26,658 meters of reverse circulation drilling). 'Twin' diamond drilling of reverse circulation drill holes represented approximately 15.4% of total drilling.
  • The Bigar Hill target area, representing approximately 1,000 meters by 1,000 meters, has been drilled on a nominal 80 meter by 80 meter grid spacing. In addition, a portion of the target area has been drilled on a nominal 40 meter by 40 meter grid spacing to provide geostatistical support for resource estimation purposes.
  • A second RC drill rig has arrived on site and is expected to be operational in February, 2012 and will commence on the Korkan and Kraku Pestar target areas. It is planned to drill Korkan and Kraku Pestar at a primary spacing of 80 meters by 80 meters for resource definition. Additionally, selected locations within both Korkan and Kraku Pestar target areas will be drilled to a nominal 40 meter by 40 meter grid spacing to provide geostatistical support and diamond 'twin' drilling of the RC drill holes will be carried out across the target areas at a nominal rate of 15% of total RC drilling.
  • Refer to Table 1 for a summary of all intersections at various cut-off grades for the results of reverse circulation drill holes BHRC055 to BHRC125 and diamond drill holes BHDD050 to BHDD070. Figure 2 shows a gram-meter total metal contour plot (intervals greater than 0.4g/t Au x thickness), of all Bigar Hill drilling to date, superimposed on topographic contours. Figure 3 shows a representative 'pseudo' long-section through Bigar Hill including recently completed infill RC drill holes. The dominant stratiform nature of the gold mineralization at Bigar Hill is clearly evident. Figure 4 shows a drill collar plan of all Bigar Hill drilling to date superimposed on topographic contours.
  • The routine reverse circulation-diamond 'twin' drilling program continues to confirm that the majority of mineralized intercepts and hence the deposit style, is dominated by layer-parallel, lithology-controlled gold mineralization.
  • There is also evidence of steeper mineralized structures in addition to the dominant, stratigraphically controlled (stratabound), gold mineralization. These intersections represent a 'bonus' and are likely to be intersected in greater numbers as the infill drilling program progresses.
  • The reverse circulation-diamond 'twin' drill holes suggest that there can be close spaced variation in gold grade, as is typical for gold deposits.
  • Multiple gold mineralized intercepts per hole are a common feature of the gold mineralization outlined to date in the Bigar Hill and Korkan target areas.
  1. CANADIAN NATIONAL INSTRUMENT 43-101 COMPLIANT RESOURCE ESTIMATION
  • Following site visits by international consultants AMC Consultants (UK), the Bigar Hill exploration database has been delivered in order to begin independent resource estimation.
  • It is planned to complete the initial Canadian National Instrument 43-101 compliant resource estimate on Bigar Hill by the end of Q1, 2012.
  • The current Bigar Hill database is based on 26,658 meters of RC drilling and 17,456.6 meters of diamond drilling for a total of 44,114.6 meters in 195 drill holes. The database includes over 140,000 analyses (gold, silver and sulfur) including 59,779 gold assays, of which approximately 23% are internationally accredited standards, blanks and routine QAQC duplicate and replicate check assays. All drill holes have been down-hole surveyed at regular intervals; with drill collars surveyed using DGPS or total station surveying methods. The topographic surface is based on detailed DGPS and total station surveying methods, with an average survey station spacing of approximately 15 meters by 15 meters. Over 2,956 bulk density measurements have been collected, using standard wax-sealed immersion methods. Over 17 diamond/RC, RC/RC and diamond/diamond drill pairs have been completed to date.
  • Both assaying and bulk density measurements have been carried out independently by SGS.
  1. 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. Soil sampling has been completed to the north and south of the currently defined 20 kilometer strike in order to attempt to determine the overall extent of the sediment-hosted gold belt which, based on the extent of mapped 'target stratigraphy', has the potential to be approximately 70 kilometers in length.
  • 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 trend and the entire sediment-hosted gold belt.
  • Exploration drill testing within the Korkan-Bigar trend will continue with wide spaced (nominal 160 meter by 160 meter), exploration diamond drill holes, in conjunction with the ongoing resource definition drilling program, to allow Avala to outline the potential size and economic potential of the sediment-hosted gold system.
  • Avala controls 100% of this newly identified sediment-hosted gold belt, which totals approximately 250 square kilometers, and intends to systematically drill test all currently defined priority target areas.

  1. 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. Reverse circulation drill samples have been prepared at the laboratory facility at Bor and assayed at the laboratory at Bor. A one metre sampling interval has been used for the Sediment-Hosted Gold project reverse circulation drilling program. 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.
