Kyzyltash BIOX Metallurgical Test Results

 

Chaarat Gold (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 completion of the Bio-oxidation ("BIOX")
first phase metallurgical test programme performed by SGS Lakefield on its
Kyzyltash gold project. The project has an unconstrained JORC-compliant
Measured, Indicated and Inferred sulphide resource of 5.4 million ounces of
gold at 3.8 g/t. Management estimate that the project has the potential to
produce approximately 300koz per annum of gold subject to the project meeting
its feasibility, permitting and development milestones.

 

The BIOX test results complement the metallurgical test results for pressure
oxidation ("POX") and Albion(TM) processing methods which were released on
23(rd) August 2022.

 

Highlights of the BIOX Metallurgical Testing Programme

-      Leach recovery for BIOX averaged 84-96% using flotation, BIOX and
carbon in leaching ("CIL").

-      This compares favourably to the leach recovery for Albion(TM) and
POX which averaged 80-90%.

The BIOX process oxidises sulphide minerals and exposes gold to recovery by
cyanidation, thereby increasing the achievable gold recovery. The highest
overall recoveries, under the conditions tested in this programme, were
achieved with flotation followed by BIOX and CIL flowsheet which were up to 6%
higher than the previously reported first stage recoveries from both POX and
Albion(TM) technologies.

 

The SGS reports on mineralogy and process testing will be available on the
Chaarat web page shortly.

 

Next Steps

-      Further investigation and variability testing will be performed on
all three processing options to confirm the first stage results thereafter.

-      Final test results will be used to conduct an economic trade-off
study to determine the preferred processing option. This study will include an
assessment on flotation and full ore processing options before proceeding with
other workstreams required towards an updated feasibility study.

 

Mike Fraser, Chief Executive Officer of Chaarat, said:

 

"The results from the BIOX test work confirm that the Kyzyltash ore is
recoverable through all three potential processing routes. It is furthermore
encouraging that the BIOX results are significantly higher compared to the
2016 study results (77% BIOX sulphide recovery). The economic trade-off study
will allow us to understand the economic impact of these strong results and
confirm the preferred processing route."

 

 

The Kyzyltash Development Project

 

Chaarat is developing the Kyzyltash gold deposit in the Kyrgyz Republic. The
deposit hosts a refractory, unconstrained resource of approximately 5.4 Moz
gold at 3.8 g/t. More than 80,000 metres of drilling have been completed to
date on the project and the current resource has been defined over 4 km of
strike length within favourable geology that could extend over more than 12 km
of strike length. In 2016 NFC (China Nonferrous Metal Industry's Foreign
Engineering and Construction Co. Ltd) subsidiary NERIN completed a definitive
feasibility study to Chinese standards assuming $565 million in capital
expenditure for an underground mine and a BIOX processing facility with ca.
75% recovery leading to an NPV(8) of $911 million based on a $1,750/oz gold
price.

 

The Kyzyltash sulphide gold deposit is in the same licence area as the
Tulkubash. Kyzyltash represents the next stage of development for Chaarat in
the Kyrgyz Republic which targets to deliver 500 koz p.a. group production
through organic growth.

 

The Kyzyltash Metallurgical Drilling and Testwork Programme

The 2021 Kyzyltash metallurgical drill programme consisted of 16 twin drill
holes totalling 3,508 metres. Drill hole locations were selected to provide
sufficient material of appropriate tonnage and grade to represent the Main and
Contact Zones of the Kyzyltash deposit. Sampling was conducted using large, PQ
diameter core to ensure enough core was available for subsequent metallurgical
testing.

In order to proceed to an updated feasibility study in accordance with
international standards, no further drilling is required on the measured and
indicated resource whereas management currently expects ca. 10 km of drilling
to be required to upgrade the existing inferred resources to measured and
indicated categories.

Sampling

The material for testing was collected from the diamond drilling programme in
the major mineralised areas of the deposit known as the Main and Contact
Zones. A total of 395 metres of mineralised core yielded 2,300 kg of material
for the current programme in addition to future variability and pilot plant
test work.  Master composites for the Main and Contact Zones were prepared
for testing, grading 2.5 g/t Au and 3.6 g/t Au respectively. The material is
considered representative of the potentially minable portion of the deposit by
both SGS and Chaarat.
