Marketwired Canada
Avala Resources Ltd. (TSX VENTURE:AVZ) (the "Company" or "Avala") is pleased to
announce updated Canadian National Instrument 43-101 ("NI 43-101") resource
estimates for the Bigar Hill and Korkan deposits, part of its Timok Gold
Project, a recent gold discovery in an emerging sediment-hosted gold belt
located in Eastern Serbia.
1. HIGHLIGHTS
In 2012 and early 2013, the Company announced initial resource estimates for the
Bigar Hill, Korkan and Kraku Pester areas. The combined mineral resources at a
cut-off grade of 0.6 Au g/t included 0.27 million ounces in the indicated
category (6.32 million tonnes at 1.3 Au g/t) and 2.4 million ounces in the
inferred category (48.7 million tonnes at 1.5 Au g/t).
The main objective of the Company's drilling since the announcement of the
initial resource estimates was to convert inferred resources to indicated
category. This was successfully done based on 75,724 meters of infill drilling,
A notional infill drill spacing of 40 meters by 40 meters was used for the
drilling program.
Based on a 0.6g/t gold cut off, the Timok Gold Project contains in situ
resources of 46.3 million tonnes grading an average of 1.56 g/t gold in the
indicated resource category for 2,318,000 ounces of gold and 8.7 million tonnes
grading an average of 1.3 g/t gold in the inferred resource category for 360,000
ounces of gold.
As a result of the infill drilling 94% of the Bigar Hill resources are now
classified as indicated resources, along with 75% of Korkan and 74% of Kraku
Pester.

Notes: (1) The effective date of the Bigar Hill and Korkan updated mineral
resource estimates is 14th October 2013.
(2) The resource estimations have been completed by Chris Arnold
MAusIMM CP(Geo) of AMC Consultants Limited (UK) ("AMC").
(3) The gold price used in this estimate was US$1250/oz. Several
phases of extensive metallurgical test work have been completed and,
based on information to date, along with possible projected
throughput rates for the entire Timok Gold Project, typical mining
costs and a range of processing costs and indicative processing
suitable gold cut off grades are considered to lie in the range of
0.4g/t to 0.8g/t.
(4) Mineral resources, which are not mineral reserves, do not have
demonstrated economic viability. The estimate of mineral resources
may be materially affected by environmental, permitting, legal,
title, taxation, sociopolitical, marketing, or other relevant issues.
(5) The quantity and grade of reported indicated and inferred
resources in this estimation are uncertain in nature and there has
been insufficient exploration to define these indicated and inferred
resources as measured mineral resources.
(6) Totals and average grades are subject to rounding to the
appropriate precision.
A summary of the mineral resource estimates using various cut offs is presented

(1) See notes under the table above.
It should be noted that the lower, eastern sector of Korkan, termed Korkan East,
has been excluded from the resource estimates. Korkan East, in part, comprises a
polymetallic style of mineralization, containing elevated levels of gold,
silver, lead, zinc and arsenic. All drill holes within the Korkan East volume
have been re-assayed for silver, lead, zinc, arsenic and sulphur and the sector
will be the subject of a separate resource estimate, currently being prepared by
AMC. A press release detailing drilling results from the Korkan East sector is
in preparation. Initial phases of metallurgical testwork on Korkan East have
also been carried out.
The Bigar Hill component of the combined resource estimate includes a
contribution for a newly discovered, small fault-bounded block, termed Bigar
North West, which is located approximately 500 meters from the northern boundary
of the Bigar Hill mineralization and which has been classified as an inferred
resource.
2. ADDITIONAL INFORMATION
Introduction
-- Avala controls 100% of this recently identified sediment-hosted gold
belt through a license holding that totals 1159 square kilometres.
-- The locations of Bigar Hill, Korkan and Kraku Pester are displayed in
Figure 1.
-- Details of the Kraku Pester drilling programs and resource estimate were
reported on January 14, 2013 and are not repeated here for brevity.
Drilling and Sampling
-- The Bigar Hill infill drilling program comprised 251 drill holes (19
diamond drill holes, "DD" and 232 reverse circulation drill holes, "RC",
including 24 RC holes with diamond drill core 'tails', "DT"). Details of
the drilling and sampling program and a comparison with the initial
phases of drilling at Bigar Hill are summarised in the table below.
Figure 2 shows the location and type of infill drilling along with a
surface projection of resource bocks above 0.6 g/t Au, subdivided by
resource category.
-- For the Korkan infill drilling program a total of 135 holes were
drilled, dominated by RC drilling and details are summarized in the
table below. Figure 3 displays the location and type of infill drilling
for Korkan, along with a plan projection of categorized resources above
0.6g/t Au.
-- The location of the Korkan East resource blocks that have been excluded
from the current resource reporting are shown in Figures 3 and 4.
-- The drill plan and a surface projection of resource blocks greater than
0.6g/t for Kraku Pester are displayed in Figure 5.
-- The Bigar Hill infill drilling program comprised 54,824 meters whilst
the Korkan infill drilling program totalled 20,890 meters. Over 75,629
primary assays were completed during the Korkan and Bigar Hill infill
drilling programs.
-- In addition to the collection and processing of primary assays, a very
large amount of check sampling and assaying has been completed, as part
of Avala's standard QAQC procedures.
-- Block model preparation and resource estimation has been completed using
Datamine and Isatis. One-meter composites (the standard Avala sampling
unit) were used to define geological boundaries and mineralized
wireframes, whilst three-meter down hole composites were used for
statistical analysis, variography and resource estimation.

Density Measurements
-- Density measurements are routinely taken every three meters down hole
from diamond drill core. The bulk density of the core billets is
measured at the SGS managed laboratory at Bor using the industry
standard wax-seal immersion method.
-- A very large number of density measurements have been collected at Bigar
Hill (5,577 measurements) and Korkan (9,326 measurements), enabling the
density to be estimated into the block models.
-- An inverse distance squared weighting algorithm was used for density
estimation during block modelling.
Resource estimation
-- Resource estimation has been completed using the geostatistical
technique, Local Multiple Indicator Kriging ("Local MIK"). Local MIK is
a form of Multiple Indicator Kriging ("MIK") where the grades are
'mapped' directly into selective mining unit ("SMU") sized blocks from a
MIK panel estimate using an intermediate stage incorporating Ordinary
Kriging ("OK") into SMU size blocks (5m x 5m x 5m).
-- At Bigar Hill a total of 17 indicator cut offs were used to define the
metal distribution within the model cells. At Korkan some 19 indicator
cut offs were used for the upper mineralised zone (MSSS) while 17
indicator cut offs were used for the other defined mineralized zones.
-- At Bigar Hill, detailed variography has been carried out on six of the
17 indicator cut offs, spread through the grade distribution, while at
Korkan five indicators were chosen for detailed variographic analysis
and modelling.
-- Statistical analysis of the composite grade distribution confirmed that,
for the great majority of mineralization at Bigar Hill and Korkan,
'outlier' samples were absent and no upper cut was applied prior to
estimation by Local MIK. At Bigar Hill, an upper cut of 8 g/t was used
for mineralization within the upper volcanic unit (MSVO).
-- The mineral resource was estimated using the Canadian Institute of
Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral
Resources and Reserves, Definitions and Guidelines prepared by the CIM
Standing Committee on Reserve Definitions and adopted by CIM Council.
The in-situ resource estimates are within the defined mineralized
wireframes and are reported at a range of lower cut off grades.
-- Based on the metallurgical information available to date, along with
possible projected throughput rates, a range of processing costs and
recoveries and a gold price of US$1250/oz., appropriate cut off grades
are considered to be in the range 0.4g/t to 0.8g/t.
Metallurgical Testwork
-- Comprehensive metallurgical test work on the Timok Gold Project
lithologies is being finalized and will be reported on when all results
are to hand and have been compiled.

3. 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 meter sampling interval has been used where
possible for the Timok 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 meter sampling interval has been used for the Timok
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 are 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 is routinely entered into geology and structural geology spread sheets
using Field Marshal software for subsequent inclusion in an acQuire database and
validation.
