Tulkubash Reserve and Resource Update
Chaarat (AIM:CGH), the AIM-quoted gold mining Company with an
operating mine in Armenia, and assets at various stages of
development in the Kyrgyz Republic is pleased to announce the
results of the revised JORC compliant Tulkubash Mineral Resource
Estimate ("MRE") and Ore Reserves ("OR") estimate following the
2021 drilling programme.
Highlights
-- Contained gold ounces in the Ore Reserves increased by 13% to
647 thousand ounces ("koz") compared to 571 koz in the 2021
bankable feasibility study (BFS).
-- Proven & Probable Reserves increased from 20.9Mt to
23.1Mt (+11%) with a slightly increased grade of 0.87 g/t compared
to 0.85 g/t (+2%) in the BFS;
-- The pit shell optimisation for the Ore Reserve was based on a
USD$ 1,600/oz gold price vs USD 1,450/oz gold price in the 2021 BFS
as per latest long term gold price forecasts.
The targeted 2021 drilling programme has resulted in an improved
Mineral Resource model which has contributed to an increase in Ore
Reserves. Contained gold in the Measured and Indicated Resources
remains unchanged at 789 koz, while Measured and Indicated
Resources decreased from 28.5 to 25.1 Mt (-12%) and gold grade
increased from 0.86 g/t to 0.98 g/t (+14%). The Inferred Resources
have decreased as a result of more conservative constraining
factors applied to the MRE. Drilling within the existing Mineral
Resource footprint demonstrated increased continuity in and between
the ore zones and was successful in improving the pit designs.
Further exploration conducted at Tulkubash during 2021
identified several additional new target areas, confirming the
Company's belief that Tulkubash has the potential for further mine
life extensions. To date, only about 5 kms of a prospective 24 km
trend has been systematically drilled. An additional 4 kms of the
prospective trend has been trenched and drill tested in 2021,
confirming further perspectivity to the northeast.
Mike Fraser, Chief Executive Officer, commented:
"I'm pleased to report the results of the 2021 drilling
programme at our Tulkubash gold project in the Kyrgyz Republic. The
drilling has delivered a 13% increase in gold in the Ore Reserve to
647koz at a grade of 0.87g/t, adding about a year of production to
what was already an economically robust project, while also
improving our understanding of this exciting asset."
UpdateD MINERAL Resource Statement
The objective of the 2021 drilling programme was to upgrade
Inferred and unclassified Mineral Resources in the mid zone and
east area for potential conversion to Ore Reserves. For further
information on the drilling campaign please refer to the 2021
release here .
The results of the 2021 drilling have been incorporated into an
updated JORC-compliant Mineral Resource Estimate. The new block
model and MRE addresses the recommendations of the external
consultants that reviewed the 2021 BFS MRE.
The table below summarizes the updated Tulkubash end of year
2021 Mineral Resource at 0.21 g/t Au cut-off grade constrained by a
USD$1,800/oz pit shell. Operating cost parameters used were as per
the 2021 BFS.

-- The Mineral Resource was estimated using 5 m x 5 m x 5 m (x,
y, z) blocks, with minimum sub-block dimensions of 1 m x 1 m x 1 m
(x, y, z).
-- The estimate was constrained to the mineralised zone using wireframe solid models.
-- Grade estimates were based on 1.5 m composited assay data.
-- The interpolation of the metal grades was undertaken using Ordinary Kriging.
-- The Mineral Resource was bounded by a pit shell based on a gold price of $1,800/oz Au.
-- A cut-off grade of 0.21 g/t Au was applied to report the Mineral Resources.

Notes to the Ore Reserve Statement:
1) This statement of Ore Reserves has been prepared by Mr. Peter
C. Carter, an independent consulting mining engineer, based on a
review of work performed by Chaarat Gold and associated technical
staff.
2) Mr. Carter is a member of the Association of Professional
Engineers and Geoscientists of British Columbia and is qualified as
a Competent Person under the JORC Code, 2012.
3) There are no Proven Reserves as drillhole density and
historical data quality do not support Measured Resources.
4) Tonnages are in metric tonnes.
5) Figures have been rounded to three significant figures.
6) Ore Reserves are reported inclusive of mining dilution (10%) and mining recovery (97.5%).
7) A gold price of US$1,600/oz was used in the preparation of the estimate.
8) Ore Reserves are based on a marginal cut-off grade of 0.22 g/t Au.
9) Estimated metallurgical recovery for the Ore Reserve is 74.0%
based on a geo-metallurgical model.
10) Reserve is contained in a minable pit design generated from
an optimised pit shell based on a gold price of $1,350/oz
The Ore Reserve has a strip ratio of 2.9:1 and an average
recovery of 74.1% representing 479,000 oz Au recovered. By-product
silver is not reported as part of the reserve as its contribution
to the project value is immaterial.
Changes from 2021 BFS
While tonnes have decreased in the EOY 2021 MRE gold grade has
increased from the BFS as has waste and strip ratio. Wire frames
have been revised, a variable rather than fixed gold recovery has
been developed. These changes are summarised in table 3. Details
can be found in the MRE Report that is available on our
homepage.

Competent Person- Mineral Resource Estimate
The information in this announcement that relates to exploration
results is based on and fairly represents information and
supporting documentation prepared by Dimitar Dimitrov, P. Geo, AIG
member and a Competent Person as defined in the 2012 edition of the
JORC Code 'Australasian Code for Reporting of Exploration Results,
Mineral Resources and Ore Reserves' and is a Qualified Person under
the AIM Rules . Mr. Dimitar Dimitrov is a full-time employee of the
company. Mr. Dimitrov consents to the publication of this new
release dated May 24(th) , 2022 by Chaarat. Mr. Dimitrov certified
that this news release fairly and accurately represents the
information for which he is responsible.
Competent Person -Ore Reserve Estimate
The updated Ore Reserve estimate was prepared by Chaarat
engineering staff at their Bishkek offices in the Kyrgyz Republic.
The work was reviewed by Peter C. Carter, BSc, MBA, P.Eng, a
consulting engineer registered in the province of British Columbia,
Canada. Mr. Carter is qualified as a Competent Person as defined by
the JORC code (2012) and a Qualified Person under the AIM Rules. He
has reviewed the technical information related to the Ore Reserves
in this press release and approves their use herein.
Quality Assurance/Quality Control Procedures: Sampling
Methodology and Quality Control
All results used in the mineral resource estimate are from
mostly diamond core drill holes, only 2020 drilling is reverse
circulation. All core samples are cut along its long axis, half
core packed, weighted and shipped to the ALS Global Laboratory in
Kara-Balta, Kyrgyz Republic for sample preparation and assay. Gold
is analysed using a 30-gramme fire assay with an atomic absorption
spectroscopy (AAS) finish. A quality control/quality assurance
protocol is employed in the programme which includes standards and
blanks in every batch of assays. External check assays are
conducted on every 20(th) sample by a second independent
laboratory, SGS Vostok Limited Lab in Chita, Russia.
Geological Modelling Procedures
Only drilling data was engaged in the Resource estimation,
although channels, trenches, and road cuts assays were used for ore
zones interpretation as well. The Tulkubash deposit is interpreted
as a brittle shear zone, formed in a shallow epithermal
environment, consisting of a SW-NE corridor of low-grade
mineralization, hosting a series of discrete, higher grade, steeply
dipping lodes. Only the oxidized portion of the mineralisation is
targeted for the planned conventional open pit mining and further
heap leaching. The ore wireframes, including low- and high-grade
types has been generated manually from section to section. Gold
grades estimation was done by using Ordinary Kriging (OK), and
Inverse Distance Weighting (IDW2) approach was used for the Silver
and density interpolation. Micromine(TM) was used in the process of
ore modelling, variography and resource estimation.
Pit Optimisation
Ore Reserves were defined as a subset of Measured and Indicated
Resources. Whittle 4X pit optimization software was applied to the
resource block model to develop a series of nested pit shells,
corresponding to a range of gold prices from $1,000/oz to
$1,800/oz.
Technical and economic parameters applied to drive the
optimization are based on those from the 2021 FS. Cost parameters
used to define the Ore Reserve are shown in the table below. A gold
price of $1,600/oz, based on consensus forecasts for the operating
period, was used to value the resulting pit shells.
The pit slopes used during the optimization varied between 49
degrees and 55 degrees based on feasibility design recommendations
for the MZ Pit area.

Gold recovery for the updated Reserve averaged 73%. Recovery was
estimated on a block-by-block basis using oxidation state and
extractions derived from metallurgical test work. The improvement
in recovery from the 2021 FS was due to the inclusion of more,
highly oxidized material from the Mid and East Zones in the
reserve.
Optimisation Results
The results of the pit optimization indicated that a gold price
of $1,350/oz produced the highest value shell with the lowest risk.
The shell was composed of seven separate entities, collectively
containing 21.8 Mt ore at a grade of 0.97 g/t Au and a strip ratio
of 2.9:1. This pit shell was selected as the basis for developing
minable pit designs.
Mine Design
The shell for each separate pit was used to guide a
computer-aided, manual design process. Constructible features such
as ramps and safety benches were designed within the optimised pit
limits to turn the three-dimensional surface into a minable pit
design. The result of the pit design process was an ore reserve
within 5% of the optimised minable resource.
The tonnage and grade in the minable pits, was adjusted for
mining dilution and ore losses expected from the mining process.
Mining dilution was calculated directly from the block model along
the ore/waste contacts. Average dilution was estimated at 10% and
varied from zone to zone. Ore losses from mining were applied at
2.5%.

Geology
* Deposit type, geological setting and style of * Chaarat Gold Project (Project) is located within Tien
mineralisation. Shan Metallogenic Belt, a Hercynian fold and thrust
belt, with length more than 2,500 km. Tien Shan belt
consists of three tectono-stratigraphic units, each
divided by major structural zones, and is thought to
represent accretionary prisms, on the margin of
proto-Eurasian continent. The Project is located in
the middle Tien Shan province, made of Ordovician -
Carboniferous fragments. Structurally, the t errain
is intensively deformed by pre and post
mineralization structural activities, dominated by SE
and NW verging fore / back thrusts and steep N-NE
strike-slip faults. Genetically, the mineralization
system could be reference to "Orogenic" and
"Intrusion Related" types. It has NE strike and is
thought to be closely related with structurally
controlled Permian aged magmatism.
* Two main host rock / mineralization types can be
outlined in the deposit. Oxidized type of gold
mineralization, hosted in Devonian silicified
sandstones of Tulkubash formation, represented by
relatively steep, NE striking lenses, controlled by
series of dilatational jogs.
The second type of mineralization is unoxidized Au zone,
containing refractory gold, hosted
in Ordovician flysch complex, dominated by fine-grained
black shales, locally appeared in
green-schist facies, and with features of comprehensive
structural deformations and contact
metasomatism. Both ore types are thought to relate to one
hydrothermal system, developed in
different facies due to difference in the host rock and the
stratigraphic position
* 2021 infill drilling (and Mineral Resource update)
was conducted in Middle Zone and East Zone, which
along with Main Pit area are part of the oxidized
Tulkubash mineralization type
