Anglo Asian Mining plc
Zafar JORC Mineral Resource completed - 6.8 million tonnes of mineralisation with average copper grade of 0.50 per cent.
Anglo Asian Mining plc ("Anglo Asian" or the "Company"), the AIM-listed gold, copper and silver producer focused on Azerbaijan, is pleased to provide a JORC Mineral Resource for its Zafar polymetallic deposit (the "Zafar deposit"). The Zafar deposit is situated in the central region of the Company's Gedabek contract area in western Azerbaijan and is approximately 1.5 kilometres from the existing Gedabek processing facilities.
Zafar deposit highlights
· 6.8 million tonnes of mineralisation with average grades of 0.5 per cent. copper, 0.6 per cent. zinc and 0.4 grammes of gold per tonne
· In-situ Mineral Resource of 28,000 tonnes of copper, 73,000 ounces of gold and 36,000 tonnes of zinc
· Angled drill holes completed since the maiden Mineral Resource was published on 16 August 2021 identified voids which has resulted in a smaller resource
· Upper part of the resource is now defined as more massive and continuous which will result in more efficient mining
· Over 302 metres of continuous mineralisation in the thickest intersection
· Total drilling to date is 40,538 metres

Anglo Asian CEO Reza Vaziri commented:
"Anglo Asian is pleased to report this JORC Mineral Resource for Zafar. While this final resource estimate is not as large as initially evaluated in our maiden JORC mineral resource, it is a considerable asset that adds significant value to our growing portfolio of resources. The upper part of the deposit is now defined as more continuous, which can be mined more efficiently and economically. Preparations at the site continue at pace, and we are on track to begin production in 2023. We look forward to updating the market on its progress."
Anglo Asian Vice-President, Stephen Westhead commented:
"This Mineral Resource estimate is now very robust under the criteria of the JORC reporting Code. The deposit can be broadly divided into an upper and lower section. The upper portion contains the main mineralisation zone where continuity of mineralisation provides for a high confidence of estimation. The lower portion exhibits less continuity with mineralisation being less massive and more irregularly distributed. The lower portion will be subject to further evaluation drilling in the future from underground.
"We are now proceeding with Ore Reserves estimation and mine planning. The location of the underground portal has been defined. Following further geotechnical drilling, access tunnelling and development work will commence this year."

Zafar deposit
The detailed JORC ('Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code) 2012 Edition') "JORC" Mineral Resource estimate for the Zafar deposit has been published on the Company's website and is available at https://wp-angloasianmining-2020.s3.eu-west-2.amazonaws.com/media/2022/03/MP-10032-Zafar-JORC-MRE-Update-r3-220316.pdf. The Table 1 report accompanying the JORC Mineral Resource estimate is available at https://wp-angloasianmining-2020.s3.eu-west-2.amazonaws.com/media/2022/03/UPG10032_Zafar_MRE_JORC_TABLE1_r0.pdf.
The initial announcement dated 19 January 2021 "New Copper and Gold Discovery at its Gedabek Licence Area" is available on the Company's website which gives the background to the Zafar property.
Zafar mineral resources - supporting work and independent expert opinion
The Company engaged Mining Plus UK Limited, the independent consulting group, to review the Company's database and provide the Mineral Resource estimate.
A preliminary mining method study comparing open pit versus underground methods has indicated that underground semi-bulk extraction by a sub-level caving system is likely to be the optimum mining method for the Zafar ore body. Stope design has commenced and a mineable shape optimiser ('MSO') was used to generate stope shapes to test the data, which resulted in a coherent stope model. A schematic ramp design to access the mineralisation has also been completed to allow for planning of condemnation drill targets and geotechnical studies.
In conjunction with Mining Plus, the Company engaged a hydrological and geotechnical consulting group ('KLM Consulting Services') to assess water issues and rock mass for mine planning and design. A structural and hydrological model was produced and the design completed for emplacing piezometer sensors for monitoring ground water.
The Company has also prepared indicative three-dimensional geology, geological structural and mineral alteration models. Data from the recent ground-based geophysical Induction Polarisation ('IP') and resistivity survey are being interpreted in conjunction with the nearby ZTEM data.

APPENDIX: GLOSSARY OF TERMS AND ABBREVIATIONS
The following definitions are extracted from the JORC Code, 2012 Edition
Indicated Mineral Resource | An 'Indicated Mineral Resource' is that part of a Mineral Resource for which quantity, grade (or quality), densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes, and is sufficient to assume geological and grade (or quality) continuity between points of observation where data and samples are gathered. An Indicated Mineral Resource has a lower level of confidence than that applying to a Measured Mineral Resource and may only be converted to a Probable Ore Reserve. |
Inferred Mineral Resource | An 'Inferred Mineral Resource' is that part of a Mineral Resource for which quantity and grade (or quality) are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade (or quality) continuity. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to an Ore Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. |
JORC | JORC stands for Australasian Joint Ore Reserves Committee (JORC). The Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC Code) is widely accepted as the definitive standard for the reporting of a company's resources and reserves. The latest JORC Code is the 2012 Edition. |
Measured Mineral Resource | A 'Measured Mineral Resource' is that part of a Mineral Resource for which quantity, grade (or quality), densities, shape, and physical characteristics are estimated with confidence sufficient to allow the application of Modifying Factors to support detailed mine planning and final evaluation of the economic viability of the deposit. Geological evidence is derived from detailed and reliable exploration, sampling and testing gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes, and is sufficient to confirm geological and grade (or quality) continuity between points of observation where data and samples are gathered. A Measured Mineral Resource has a higher level of confidence than that applying to either an Indicated Mineral Resource or an Inferred Mineral Resource. It may be converted to a Proved Ore Reserve or under certain circumstances to a Probable Ore Reserve |
Mineral Reserves or Ore Reserves
| An 'Ore Reserve' is the economically mineable part of a Measured and/or Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at Pre-Feasibility or Feasibility level as appropriate that include application of Modifying Factors. Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified. |
Mineral Resource | A 'Mineral Resource' is a concentration or occurrence of solid material of economic interest in or on the Earth's crust in such form, grade (or quality), and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity, grade (or quality), continuity and other geological characteristics of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge, including sampling. Mineral Resources are sub-divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories. |
