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.

Notes to the Ore Reserve Statement:

 

 

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.

The largest portion of the Ore Reserve is contained in the Main Zone (MZ) Pit (19.8 Mt). To the northeast of MZ lies the Mid Zone, composed of six small satellite pits, accounting for a further 3.1 Mt of ore. Further northeast lies the East Zone, which contains another 0.2 Mt in a single separate pit. The East Zone is not fully drilled off and offers the opportunity to continue growing the Ore Reserve in the coming drill seasons.

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 24th, 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 20th 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. MicromineTM  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%.
