Anglo Asian CEO Reza Vaziri commented :

"Zafar's maiden Mineral Resource estimate is extremely encouraging and will help underpin the Company's future long-term production growth. Located in close proximity to our existing Gedabek processing plant, there are significant operational and geographical synergies which will help us rapidly develop this resource. We are now highly focused on completing the final mineral reserve estimation of the deposit by the end of the year and successfully bringing Zafar into production as soon as possible."

Anglo Asian Vice-President, Stephen Westhead commented:

"The Zafar drilling results are very encouraging and increase the resources, the reserves and, ultimately, the metal production of the Company. Exploration is being fast-tracked to assess the economics of the project with a view to starting production in 2023. The team are highly motivated by this aggressive approach and are working to rapidly complete the mineral reserves and mine plan of this challenging project. In the vicinity of the Zafar deposit are a number of other exciting prospects where ZTEM anomalies have been defined. With the ramp-up of drilling capacity, the Company looks forward to further announcements as this project develops. The geology team at Gedabek has recently been strengthened and is supported by new equipment including XRD analysers, three-dimensional core logging tools and new technical software."

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/2021/08/13121825/Zafer_Mineral_Resource_Estimate.pdf . The table one report accompanying the JORC Mineral Resource estimate is available at https://wp-angloasianmining-2020.s3.eu-west-2.amazonaws.com/media/2021/08/13120129/ZafAr_MRE_JORC_TABLE1.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.

Current work at the Zafar deposit

The Company is currently employing four core drill rigs over the planned central mine area. One additional rig is working on extension drilling and condemnation drilling for the proposed underground decline and ramp system. Four drill rigs are configured for oriented drill core to define structural orientations in detail and large core diameter geotechnical drilling for rock mass classification purposes. Rock strength property tests are being conducted on the drill core. Borehole hydrogeological measuring equipment is being used to measure groundwater levels, water recharge and chemistry, all of which are critical for mine design.

Investigation of the mineralisation is ongoing and includes microscope studies of the deposit minerals and rocks to determine the mineralogy, the grain size and mineral interlocking relations. A substantial density dataset has been established as required for tonnage estimation. These data will be used in the geometallurgical modelling to assess the optimum ore beneficiation methods.

Geotechnical data including rock quality test and hardness in drill cores are also being collected, which are critical for mining method studies and underground development scheduling.

Composite sampling for metallurgical test-work to complement the geometallurgical studies has also been conducted to assess the best ways to extract the ore minerals for future optimised production. Initial test-work is being carried out at the Company's laboratories to determine the required further work for mineral deportment studies and process optimisation.

A detailed drill programme is underway for further Mineral Resource definition, Mineral Resource extension and engineering to provide data for the final Mineral Resource estimation, which is planned to be released before the end of 2021. Ore Reserve estimation will then follow. Mining equipment selection, staffing, infrastructure and process design will start in late 2021. The Company will then develop the final geological model. This will include mineralisation and country rock determination, a structural model, a hydrological model and a geotechnical model that will all feed into the rock mass model for detailed mine design.

Zafar mineral resources - supporting work and independent expert opinion

The Company engaged the independent consulting group, Mining Plus UK Limited, to review the Company's database and provide the interim maiden Mineral Resource estimate. In addition, the drillhole spacing required for the final JORC classified Mineral Resources estimation has been defined so the next stage of work can be directly focused on resource drilling.

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 that resulted in a coherent stope model. 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.

456 samples were sent to the independent ALS Laboratories for analysis, involving four-acid digest and multi-element analysis with gold assay. These independent assay results were used to validate the quality assurance and quality control ('QA/QC') data acquired at the Company laboratory, which included the use of duplicates, blanks and certified reference materials (CRMs).

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.
