SUMMARY
NEOSC
Geomin Ltd. (“NEOSC”) was retained by Supatcha Resources Inc. (“Supatcha”) in
August 2010 as consultants to complete a resource statement specific to the
Barlevskoye and Vynohradiv licenses (known as the “properties. The Barlevskoye
and Vynohradiv licenses are 4.917 square kilometers (“km²”) and 6.75 km²,
in size, respectively, which means the total area covered by the
properties, is 11.667 km². Mr. Graig Parham, a principal of NEOSC and a
Competent Person, conducted a property visit on August 18th and 19th,
2010.
The
Barlevskoye Mining District lies within the Transcarpathian Terrain.
The properties fall within the Carpathian Neogene volcanic belt which has
been a source of gold production since the Roman era. Numerous
gold-silver-lead-zinc occurrences exist near the properties. The Berehiskyi
Property/ Mine is adjacent to the properties and is considered
important.
Historic
drilling was conducted at both the Barlevskoye and Vynohradiv properties
(63 drillholes and 2 drillholes, respectively). Drilling highlights from
within the Barlevskoye Property include: 3.6 grams per tonne gold (“g/t Au”),
31.6 grams per tonne silver (“g/t Ag”), 3.89 per cent (“%”) lead (“Pb”),
and 5.68 % zinc (“Zn”) across 32.6 meters; 1.9 g/t Au, 248.40 g/t Ag, 9.36
% Pb and 1.66 % Zn across 29 meters; 12.2 g/t Au, 48.7 g/t
Ag, 3.27 % Pb, and 6.79% Zn across 5.3 meters; and 1.1 g/t Au,
1021.7 g/t Ag, 1.06 % Pb and 2.63 % Zn across 27 meters. Drilling
highlights from within the Vynohradiv Property include 5.1 g/t Au across
2.1 meters.
Based on
known gold and polymetallic occurrences at the properties, the proximity to
known gold-silver-lead-zinc epithermal mining operations (the Berehiskyi
Property), and favorable geology, the potential to discover an important gold
and/or polymetallic occurrence(s) / deposit(s) at the Barlevskoye and Vynohradiv
properties exists.
INTRODUCTION
This
report is written as a Resource Statement for the Barlevskoye and Vynohradiv
licenses (“the properties”). This Report has been undertaken in accordance with
the requirements of the reporting guidelines of the Canadian Securities
Administration National Instrument 43-101 ("NI 43-101") and CIM Standards on
Mineral Resources and Reserves. The NI 43-101 is a widely used and
internationally accepted standard for the reporting of mineral
deposits.
NEOSC
Geomin Ltd. (“NEOSC”) was retained by Supatcha Resources Inc. (“Supatcha”) in
August 2010 as consultants to complete a resource statement specific to the
Barlevskoye and Vynohradiv licenses (known as the “properties. The Barlevskoye
and Vynohradiv licenses are 4.917 square kilometers (“km²”) and 6.75 km²,
in size, respectively, which means the total area covered by the
properties, is 11.667 km². Mr. Graig Parham, a principal of NEOSC and a
Competent Person, conducted a property visit on August 18th and 19th, 2010 to
assess the type and extent of known mineralized zones at the
properties. The supporting documents which were used as background
information are referenced in this Report in the ‘History’
and ‘Geological Setting’ sections below. The nature and extent to
which these documents have been used is discussed below in the section
‘Reliance on Other Experts’.

Any
reference in this Report to the ‘current author’ refers to Mr.
Parham. Unless otherwise stated, all coordinates are presented in the World
Geodetic System (WGS) 1984, Universal Transverse Mercator (UTM) Zone
12. For the purpose of reporting historical work, there are references to
Soviet era resource estimates in this report. The Soviet era resource
estimates are only referred to as a point of historical significance, and
as an indication of the significance to other known Soviet resources and/or
reserves. According to the Soviet guidelines for Resource Classification,
“C1” and “C2” resource estimates are made according to strict guidelines
set forth by the USSR State Committee on Reserves, while “P” category
resource estimates can be made by local teams or state agencies and are of
a varying quality and standards. “C1” resources are carefully estimated
from data derived by drilling, surface and underground sampling. These
resources are used to make a pre-feasibility study and to define the nature
of the resource for future planning. Soviet feasibility studies conform to
industry standards, including mineralogical, mining and metallurgical
evaluations in addition to the resource estimate. Pending the outcome of
data verification, the Soviet “C1” resource category may be the equivalent
of or reclassified as a NI 43-101 compliant “indicated” resource
estimate. “C2” resources are delineated by drilling and in some cases; they
may be supported by underground sampling (similar to ‘inferred’). Drill
spacing and if available, underground sampling is wider and less detailed
than is required to support a “C1” estimate. Pending the outcome of data
verification, a “C2” category resource may support a NI 43-101 compliant
“inferred” resource estimate. “P” resources are estimates of the
“potential” resource of a prospect, often based on some limited sampling
and geologic inference to similar deposits elsewhere. “P” resource
estimates are referred to in this report for historical purpose and an
indication as to what the Soviet era workers thought, “may be the
potential” for a particular prospect. These estimates are often made with little
hard geologic information and must be viewed with caution.

ACCESSIBILTY, CLIMATE, LOCAL
RESOURCES, INFRASTRUCTURE, AND PHYSIOGRAPHY
The
properties are accessed by driving on narrow, well paved roads south from Lviv
to Mukachevo on highway E50 for 214 km, then south from Mukachevo to Barlevskoye
on highway E81 for 35 km. The Barlevskoye Property is located 1.5 km to
the east of the town of Berehove. The village of Vynohradiv is located 10
km southeast of Berehove along highway E81, and the Vynohradiv Property is
situated 2.0 km north of the village. The adjacent Berehiskyi Property
lies between Barlevskoye and Vynohradiv properties, 0.8 km north of the village
of Berehiskyi.
The
climate in the region is mild and moderately continental with cool,
wet summers and mild winters. The Carpathian Mountains protect the region
from the cold north winds. Average temperatures in the region are 8 degrees
Celsius (°C), with lowest average temperatures in January (minus 4°C) and
highest in July (21° C). Average annual precipitation ranges from 700 to
1000 mm, with the highest amount of precipitation falling during the spring
and summer months.
6
Agricultural
activity surrounds the property, producing mostly grapes. Part of the
Barlevskoye Property is under the eastern portion of the town of
Berehove.
Any
necessary local labor could be sourced from either Berehiskyi (pop.
1,500), which supplied 70-80 employees during the last mining operation at
the Berehiskyi Mine, and Berehove, with a population of approximately 30,000
people. Mukachevo is 30 km to the north and is the closest large city and
also has an assay laboratory capable of processing 1000-1500 samples per
month. A railroad runs through both Berehiskyi and Berehove, and rail
tracks connected to this railroad run within 2 km of the Berehiskyi Mine.
Ukraine has a 99.4 per cent (%) literacy rate. The largest ethnic group in
the region is Hungarian comprising 75%, while the remaining 25% comprising
mostly of Ukrainians, Russians and Russins.
In 1999,
a processing plant was built at the Berehiskyi Mine with a capacity
to process 120,000 tons of ore per year with a 60,000 ton per annum
crusher. In 2002, a scrubber, jaw crusher and Knelson concentrators were
added, on the 2nd and 3rd stages of beneficiation. The plant also employed
a gravity circuit without any flotation. The plant has a 5 hectare (ha)
land allotment, but is considered to be small in case a bigger operation is
warranted. The ore storage area is capable of storing some 25,000 tons
of ore. In Ukraine, there are no smelting facilities for base metals,
meaning concentrate must be exported to Romania, Slovakia, Hungary, or even
Scandinavia. The Berehiskyi Mine was closed in January 2007.
HISTORY
The
region has been mined dating back to the 12th century, when the Holy Roman
Empire began to mint silver coins. During the 17th century, small scale
mining of the deposit occurred while controlled by the
Austro-Hungarian.
At the
end of the 1940s and 1950’s, deposits in the area were mined for gold
and silver (quartz-sulphide veins). The Berehiskyi deposit was discovered
during this time, while exploration for kaolinite-alunite (alteration) was
taking place.
During
the 1960’s, lead-zinc (Pb-Zn) and gold (Au) mineralization was recognized
at Berehiskyi. The discovery of gold-rich quartz stockworks, in 1972,
within the upper levels of the Berehiskyi mineralized zones led to
extensive exploration. More than 2000 drill holes were completed, and over
30 km of underground workings on six levels were developed in the late
1980’s.
In 1990,
the C1+C2 reserves of the Berehiskyi deposit were approved by the USSR GKZ
(reportedly contained 18,709,300 t of 1.88 g/t Au; 38.35 g/t Ag; 2.07%
Pb and 4.76% Zn). This was based on drilling and underground workings. A
P1+P2 forecast Russian resource was calculated for the Barlevskoye Property
based on exploration drillholes and no underground workings.

“P”
category resource estimates are referred to in this report for historical
purpose and an indication as to what the Soviet era workers thought, “may be the
potential” for a particular prospect. These estimates are often made with little
hard geologic information and must be viewed with caution.
Recently,
mining took place at the Berehiskyi Property from 1999 to 2006
by Zakarpolymetally, a local subsidiary of a government company called
Ukrpolmetally. Approximately 68 exploration diamond drillholes were drilled
(by the USSR Ministry of Geology) at the Barlevskoye Property and 22
drillholes at the Vynohradiv Property (by the USSR Ministry of
Geology).
The
historic data was provided in the form of paper summary drill sections
(not for each hole; not including collar data). No drill hole
samples/rejects or drill core was available to re-log or re-sample to verify
either the assay grades or the summary geology reported. Geology was
reported as overburden, rhyolite or with no reference to host lithology.
The integrity and accuracy of the data available can not be verified and
the resulting resource estimate and interpretation can not be guaranteed as
it is based entirely on the available historic drill data where accuracy
can not be confirmed. A field examination indicates the historic drill grid
no longer exists and permanent drillhole collar locations are not present. As a
result, the accuracy and integrity of the drill hole collar locations as
reported can not be verified. Since the historic drill grid and all
previous drill collar locations can not be accurately relocated and verified,
the historic data may need to be re-validated with an extensive drill
campaign.
GEOLOGICAL
SETTING
The
Barlevskoye and Vynohradiv properties are located in western Ukraine in
the Transcarpathian region, approximately 8 km from the Hungarian border.
The polymetallic (Au-Ag-Pb-Zn) mineralization occurs along a Neogene
volcanic chain in the Inner Carpathian orogenic belt, and covers a vertical
interval of several hundred meters. The Inner Carpathian volcanic belt is part
of the Alpine-Balkan-Carpathian- Dinaride (ABCD) orogen. The ABCD orogen
was a result of the collision of Eurasia with the Africa, Arabian, and
Indian plates, from the Mid/Late Cretaceous to
Late Eocene/Oligocene.
The
subsequent closure of the Tethys oceanic basin, the indentation of
continental microplates, and probable oceanic slab break-off
and asthenosphere incursion formed the Inner Carpathian orogenic belt from
the Oligocene to Recent. The main subduction event, during which the ocean
basin was consumed, occurred in the late Paleogene to middle Miocene.
Calc-alkaline volcanism and intrusive activity during the Miocene, is
believed to be responsible for the numerous Au- Ag-Pb-Zn vein deposits in
the Inner Carpathians.
8
There are
three stages of volcanism for the Inner Carpathian volcanic belt. The early
stage (17.5 to 14.0 Ma) consists of rhyolitic volcanics. The middle stage (13.5
to 9.3 Ma) includes lavas and andesitic volcaniclastic aprons and
andesitic-basaltic extrusions. The late stage (8.0 to 1.6 Ma) includes
andesites and basalts. The gold polymetallic mineralization in the Inner
Carpathian volcanic belt is genetically related to the early stage of
volcanism and is mainly concentrated in the Barlevskoye area. The Inner Arc,
around the town of Berehove, experienced significant acid volcanic
(mainly rhyolites) activity during the Badenian and Sarmatian.
The
property geology consists of volcanic caldera(s). The Barlevskoye Property
is related to the eastern rim of the caldera, which is filled with middle
Miocene volcanic sedimentary rocks. The basement rock underlying the
volcanic structure consists of Jurassic clay-rich shales, limestones, and
spilites. Overlaying this Jurassic unit are rhyolite ash tuffs (lower tuff
unit), followed by argillites and sandstones (lower sedimentary unit),
agglomeratic rhyolite tuffs (middle tuff unit), and caldera lake sediments
(upper sedimentary unit) consisting of shales and argillites with
sandstone and tuffite layers (upper tuff unit).
The
tectonic features of the area were formed during subsidence of
the intracaldera blocks. The Barlevskoye mineralization is hosted by faults
within intracaldera fill. At the Berehiskyi Mine, mineralization is mainly
associated with the east-west trending fault systems. These faults are
cut by two sets of southwest-northeast- and south-north-trending faults,
including fault VI which hosts the mineralization which was the focus of
mining. The central portion of the fracture system is called the axis
fault fracture zone. Mineralization is most intense where the axis
fault zone intersects the east-west faults.
At
Barlevskoye most veins strike to the northeast, dipping generally to the
northwest and north at 70-80 degrees. A stockwork style vein in the
Berehiskyi Mine trending southwest-northeast hosts most of the known
mineralization. This trend is consistent with the veins observed at the
Barlevskoye Property, indicating that the Barlevskoye Property may host
mineralization which is a continuation of the mineralization in the
Berehiskyi Mine. Geophysical data has detected the presence of a porphyry
intrusion at approximately 1,000 m depth, suggesting Berehiskyi and
Barlevskoye may represent a shallow portion of a porphyry-epithermal
system. The Vynohradiv Property is believed to be a satellite caldera east
of the Berehiskyi and Barlevskoye area. Geochemical anomalies have been observed
at the site, along with barite and silver (Ag) mineralization.
DEPOSIT
TYPES
Epithermal
High
sulphidation epithermal deposits (Barlevskoye and Vynohradiv) occur as veins,
vuggy breccias and sulphide replacements ranging from pods to massive
lenses associated with high-level hydrothermal systems marked by
acid-leached, advanced argillic and siliceous alteration. Metal
associations in these deposits include variable amounts of precious (Au-Ag)
and base (Cu-Pb Zn) metals and variable gangue mineralogies. Irregular
deposit geometries are the result of host rock permeability and the
orientation of ore-controlling structures. Multiple, crosscutting composite
veins are common.
9
Recent
research indicates that these deposits form in sub aerial
volcanic complexes or composite island arc volcanoes above degassing magma
chambers. The deposits commonly contain multiple stages of mineralization,
presumably related to periodic tectonism associated with increased
intrusive activity and magmatic hydrothermal fluid generation. The age of
the deposits are commonly Tertiary to Quaternary, however, some deposits
have been dated Mesozoic and/or Paleozoic in volcanic belts. Rock
types associated with epithermal deposits include a subaerial
andesitedacite- rhyodacite pyroclastics and flows as well as their
subvolcanic intrusive equivalents. It is also thought that permeable
intervolcanic sedimentary rocks can act as sites of mineralization. The
country rock surrounding epithermal veins is commonly extensively altered
even though the vein walls may be sharply defined. It is also not uncommon
to find large, highly colored supergene gossans covering epithermal
ores.
MINERALIZATION
The
mineralization style at the Barlevskoye Property is similar to that at the
Vynohradiv Property. The mineralization occurs as sulfide, quartz,
quartz-sulfide, quartz-barite, and carbonate veins and veinlets,
disseminated and impregnated zones, and as stockwork bodies. The four
stages of mineralization distinguished are the sulfide stage, quartz-barite
stage, carbonate-quartz stage, and carbonate-goethite stage. The stages are
separated by tectonic crushing and brecciation, and are characterized by
sharp disequilibria between mineral assemblages of the adjoining
stages.
The
paragenetic sequence for the sulphide stage began with the precipitation
of ankerite followed by pyrrhotite, pyrite + marcasite, sphalerite, galena
+ Ag sulfosalts, chalcopyrite, tennantite and gold. The pyrrhotite commonly
occurs as relict grains in pyrite-marcasite aggregates and as fine
inclusions in iron (Fe)-rich sphalerite. Pyrite replacement of pyrrhotite
and marcasite is often observed. Relatively coarse grained and zoned
sphalerite crystals replace pyrite-marcasite aggregates. In the
late peripheral sphalerite zones, syngenetic galena growth began. Galena is
the main carrier of economic silver (up to 800 grams per tonne silver (“g/t
Ag”). Small quantities of chalcopyrite and tennantite occur in sulphide and
quartz-sulphide aggregates. Sulphide stage mineralization decreased in
intensity from the central lower parts of the system to the upper
periphery. This trend is accompanied by a transition from
massive, coarse-grained pyrite, sphalerite-galena veins and impregnated
zones to disseminated sulphide zones and veinlets with prevalent
pyrite-marcasite-sphalerite-galena associations. The peripheral parts of
the mineralized zones are dominated by metastable mineral phases and
textures indicative of metastable crystallization.
The
quartz-barite mineralization stage began with minor fluorite and
massive quartz veins. The barite crystals in the quartz matrix are
associated with recrystallization and dissolution of quartz, and oxidation
of galena and sphalerite aggregates. Galena was then replaced by anglesite,
and gold remained in the quartz matrix during dissolution.
10
The
carbonate-quartz stage is marked by the development of massive fine-
and medium-grained carbonate veins. During this stage, two quartz
generations are recognized: amethyst quartz-chalcedonic druzy aggregates
(quartz) filling cavities, and clear medium to coarse comb quartz formed by
recrystallization of early vein quartz material. The second generation of
quartz is commonly associated with a second generation of barite, which is
present as fracture fillings and is disseminated in the altered wall rocks.
Gold was transported from the mineralized zones and re-deposited during
this stage. The carbonate-quartz stage consists of two main zones;
Secondary quartz occurs mainly in the deep part of the axis fault zone. It
is also present where the southwest-northeast- and south-north-trending
fault systems intersect the east-west faults; tertiary quartz formed in the
upper peripheral parts of the east-west-trending fault system.
The
carbonate-goethite stage is characterized by tertiary carbonate,
jarosite, goethite, cinnabar, and tertiary barite mineral assemblages. The
tertiary barite occurs as small prismatic druzy crystals in kaolinite and
kaolinite-dickite metasomatites. Gold occurs in association with goethite
and barite. Fluid inclusion and isotopic data revealed that the
mineral-forming process was controlled by three major fluid types: deep
fluid, shallow saline formation waters, and shallow, low salinity,
heterogenic (vapor ± condensate) sulfate-bicarbonate waters.
The deep
hot fluid formed from deeply circulating meteoric waters in the
sedimentary metamorphic basement rocks, with heat and mass transfer from a
magmatic system. Tectonic
brecciation occurring between mineralization stages allowed
multistage introduction of deep fluid into the ore-forming system. Shallow
saline formation waters, representing the pore fluid, evolved in volcanic
sedimentary units. The sulfatebicarbonate waters were formed by the mixing
of rising deep hot gases with cold shallow meteoric water. These fluids
accumulated in the upper peripheral parts of the system and were
responsible for the precipitation of barite. Mineral zoning is mainly
controlled by the intersection of the east-west-trending fault system, the
fault zone which is spatially connected with the caldera rim and the axis
fault zone. The axis fault served as the main fluid conduit, while the east-west
fault system provided lateral fluid distribution. The Barlevskoye
Property exhibits characteristics that are consistent of an intermediate
sulphidation, epithermal-precious metal deposit. These types of
deposits are very common in the Transcarpathian region of Ukraine (Table
3). The grades listed in Table 3 have been verified by a Competent Person.
The main purpose of the table is to display the number and types of
deposits in the Transcarpathian region.

DRILLING HISTORY
Approximately
68 exploration diamond drillholes were drilled at the Barlevskoye Property and
22 drillholes at the Vynohradiv Property. The drillholes were completed
during the 1970’s and 1980’s, with the bulk of drilling occurring during
the 1970’s. Approximately up to 100 m of overburden overlies portions of
bedrock at the Barlevskoye Property, and mineralization extends to depths of
about 400 meters.
Drill
sections were provided by Zolotivorota (“Golden Gate”), however, spatial
locations (i.e. UTM coordinates for specific drill collars) are unknown.
The sections were translated from Russian to English and digitized and are
shown graphically. Drill sections from the holes drilled at Vynohradiv were
not available although the best drill intercept was reported to be 5.1
grams per tonne gold (“g/t Au”) across 2.1 meters. Highlights include: 3.6
g/t Au, 31.6 grams per tonne silver (“g/t Ag”), 3.89 per cent (“%”) lead (“Pb”),
and 5.68 % zinc (“Zn”) across 32.6 meters; 1.9 g/t Au, 248.40 g/t Ag, 9.36
% Pb and 1.66 % Zn across 29 meters; 12.2 g/t Au, 48.7 g/t Ag,
3.27 % Pb, and 6.79% Zn across 5.3 meters; and 1.1 g/t Au, 1021.7
g/t Ag, 1.06 %Pb and 2.63 % Zn across 27 meters.
The veins
in the Barlevskoye Property strike to the northeast, generally dipping at
70 to 80 degrees to the northwest. The veins at the adjacent Berehiskyi
Property have been described as 0.6 to 8.4 m thick, which may provide a
clue as to the size of the veins which may be encountered at the Barlevskoye and
Vynohradiv properties.
The
deepest hole reportedly drilled in the area (at Berehiskyi; not on
the properties) discovered a porphyry intrusion at about 1,000 m depth.
Drilling also encountered thermal waters at depths of 900-1000 m at
Berehiskyi.
Groundwater
encountered in the area occurs at approximately +115m RL.
Iron rich water can be found at 20 m below the surface along with
elevated levels of lead, indicating the dissolution of the sulfides in the
subsurface. Previous drilling in the northern part of the Barlevskoye
Property contained core chips of galena & sphalerite mineralization,
banded quartz-sulphide mineralization, and breccia (solenite-sphalerite).
These samples reportedly contained greater than 15 g/t Au and 60% combined
Pb+Zn.

The
historic data was provided in the form of paper summary drill sections
(not for each hole; not including collar data). Geology was reported
as overburden, rhyolite or with no reference to host lithology. The
integrity and accuracy of the data available cannot be verified and
interpretations cannot be guaranteed as it is based entirely on the
available historic drill data where accuracy cannot be confirmed.
SAMPLING METHOD AND
APPROACH
The
historic data was provided in the form of paper summary drill sections (not
for each hole; not including collar data or recoveries). No drill hole
samples/rejects or drill core was available to re-log or re-sample to
verify either the assay grades or the summary geology reported. Geology was
reported as overburden, rhyolite or with no reference to host
lithology.
Consequently,
sample quality and biases, descriptions of rock types, geological controls,
true widths of mineralized zones, and parameters used to establish
sampling intervals are not known.
SAMPLE PREPARATION, ANALYSIS
AND SECURITY
No aspect
of the sample preparation was conducted by an employee, officer, director
or associate of NEOSC Geomin Ltd., Zolotivorota (“Golden Gate”) and/or Supatcha.
As the author was not directly involved with the historic
exploration completed to date throughout the properties, he had no control
over reported samples. There is no way of verifying the reported results
from previous work and/or the adequacy of sample preparation, security,
analytical procedures. As well, no information exists specific to the
laboratory, sample preparation, assaying and analytical procedures used.
The results should be treated as historic results only; however, the author
believes they are relevant and important specific to the
exploration potential of the properties.
DATA VERIFICATION
No rock
samples were collected by NEOSC Geomin Ltd. The author was not involved
with exploration prior to 2010, and therefore, had no control over
sample collection or reported results as listed in the report. The
historic data was provided in the form of paper summary drill sections
(not for each hole; not including collar data). No drill hole
samples/rejects or drill core was available to re-log or re-sample to verify
either the assay grades or the summary geology reported. Geology was
reported as overburden, rhyolite or with no reference to host
lithology.
The
integrity and accuracy of the data available can not be verified and
interpretations can not be guaranteed as it is based entirely on the
available historic drill data where accuracy can not be confirmed. A
field examination indicates the historic drill grid no longer exists and
permanent drillhole collar locations are not present. As a result, the
accuracy and integrity of the drillhole collar locations as reported can
not be verified. Since the historic drill grid and all previous drill
collar locations cannot be accurately relocated and verified, the
historic data may need to be re-validated with an extensive drill
campaign. A rigorous quality assurance and quality control program is
warranted. When managing ongoing exploration programs up to 20 per cent of
all samples should be check assayed and analytical standards and field
duplicates should be analyzed regularly to ensure quality assurance and
quality control.

ADJACENT PROPERTIES
The
Berehiskyi Property, which lies between the southern limits of the Barlevskoye
and Vynohradiv properties, is the most explored and developed property
among the three (currently owned by the Ukraine Government). This is mainly
due to the fact that it outcrops at surface, unlike Barlevskoye and
Vynohradiv. The Berehiskyi Mine was discovered in the 1950’s (silver) and
lead, zinc and gold mineralization was recognized in the 1960’s. In 1990,
C1+C2 reserves were approved by the USSR GKZ. Approximately 2000 drillholes
were completed at the Berehiskyi Property, and between 1999 and 2006 the
deposit was mined by Zakarpolymetally. The seven year mining operation
focused mainly on stockwork type mineralization, which is locally
classified as gold only ore. Approximately 700 kg of gold was produced.
The mining operation was suspended in January 2007. The author visited
the Berehiskyi Property on August 19th, 2008.
The seven
year operation of the mine proved to be uneconomical as the mine was put
into production mostly for political reasons. The mine was seen as a
pilot project, focusing on gold ore only. Began is reportedly the
largest polymetallic deposit in the area according to one source. Located
about 12 km northwest from the village of Berehiskyi (exact
location unknown), it reportedly contains a 500,000 tons of lead and zinc,
with a combined grade of seven percent. Overlaying the deposit is a
1,000,000 ton barite cap.
OTHER RELEVENT DATA AND
INFORMATION
The
current legal framework governing the mining industry in Ukraine is the
Code of Ukraine on the Subsurface (the subsurface code) and the Laws of
Ukraine on Mining.
INTERPRETATION AND
CONCLUSIONS
Based on
a review of the historic data and observations made in the field, the
Barlevskoye and Vynohradiv properties have the potential to host a large
epithermal polymetallic gold deposit(s). The Berehiskyi Property/Mine,
directly adjacent and between these two properties, has recently been
mined. The Barlevskoye Property has the potential to be a continuation of
the adjacent Berehiskyi Property/Mine.
RECOMMENDATIONS
Based on
known gold and polymetallic occurrences at the properties, the proximity to
known gold-silver-lead-zinc epithermal mining operations (the Berehiskyi
Property), and favorable geology, the potential to discover an important gold
and/or polymetallic occurrence(s) / deposit(s) at the Barlevskoye and
Vynohradiv properties exists. Therefore, an aggressive exploration program
is warranted.
