Anglo Asian Vice-President, Stephen Westhead commented: "We continued to make solid progress with our exploration campaign in the second half of last year, with the exciting discovery of the Hasan vein at Gosha. In addition, we pursued our exploration programmes at Gilar, Gedabek and Gadir with a view to strengthening our reserves base and identifying new targets.
"Our drilling programme at Zafar has continued to demonstrate very encouraging results and we plan to commence production next year, following the publication of the final mineral resource estimate and subsequent mineral reserves estimate and mine design."

Notes to Editors:
Anglo Asian Mining plc (AIM:AAZ) is a gold, copper and silver producer in Central Asia with a broad portfolio of production and exploration assets in Azerbaijan. The Company produced 64,610 gold equivalent ounces ("GEOs") for the year ended 31 December 2021.
In September 2021, the Company announced a transaction with the Government of Azerbaijan which grants it three additional concessions with a combined area of 882 square kilometres, including the Garadagh porphyry copper deposit, with a Soviet classified resource of over 300,000 tonnes of copper. The transaction is subject to ratification by the parliament of Azerbaijan.
In December 2021, the Company undertook a private placement which acquired 19.8 per cent. of Libero Copper & Gold Corporation ("Libero"). The transaction was completed in January 2022. Libero is listed on the TSX Venture Exchange in Canada and owns, or has the option to acquire, several copper exploration properties in North and South America, including Mocoa in Colombia, one of the world's largest undeveloped copper-molybdenum resources.

Gedabek geological work
Gedabek open pit
In H2 2021, 24 reverse circulation infill drill holes were completed for a length of 1,969 metres in pit 5 and pit 9. Good copper grades in these copper-rich areas were encountered with notable intersections as follows:
Hole i.d. | Intersection | Weighted average grades | |||||
Depth from | Depth to | Downhole length | Gold | Silver | Copper | Zinc | |
Metres | Metres | Metres | g/t | g/t | % | % | |

Zafar Deposit
The maiden Mineral Resource estimate for the Zafar deposit was published on 16 July 2021. The final Mineral Resource will be published by the end of April 2022.
40 core drill holes totalling 20,113 metres were completed with 34 drill holes returning grades above reportable limits. One drill hole encountered abundant sulphide mineralisation with a thickness of 133 metres and grading 0.85 per cent. copper, 1.35 per cent. zinc and 0.58 grammes of gold per tonne. Bench scale X-RAY diffraction (XRD) analysis commenced in H2 2021. This uses a portable machine to undertake geochemical analysis of core samples. The results are obtained in "real time" without the need to wait for laboratory analysis, facilitating a better focused drill programme.
Notable drill intersections were as follows:
Hole i.d. | Intersection | Weighted average grades | |||||
Depth from | Depth to | Downhole length | Gold | Silver | Copper | Zinc | |
Metres | Metres | Metres | g/t | g/t | % | % | |

Gedabek and Gadir underground mines
The Gedabek and Gadir underground mines are now connected and form one continuous underground network of tunnels accessible from both the Gadir and Gedabek portals. Both underground drilling and mapping continued in H2 2021. The underground drilling was conducted along the tunnelling connecting the Gedabek and Gadir portals. 22 core drill holes with a total length of 2,360 metres were completed.
Notable intersections were as follows:

Gilar
The core drilling programme which commenced in the first half of the year continued in H2 2021. Seventeen surface core drill holes were completed for a total length of 9,881 metres. The drilling is allowing the determination of zone continuity and has revealed a new mineralisation body, which is a south-west continuation of the deposit. The Company continues to assess the economic feasibility of tunnelling for exploration to allow for underground drilling and bulk sampling. Notable intersections comprised 3.1 metres at 8.22 grammes of gold per tonne, 3.1 metres at 7.87 grammes of gold per tonne and 1.85 metres at 10.33 grammes of gold per tonne.
Avshancli
92 reverse circulation drill holes with a total length of 2,176 metres were completed at Avshancli-1 and 9 reverse circulation drill holes with a total length of 1,022 were completed at Avshancli-2 in H2 2021. The geological work to date at Avshancli-1 shows discontinuous surface mineralisation with gold grades dropping off from the surface as the structures narrow with depth. Given the distribution of mineralisation, economic volumes of ore are likely to be small. It is unlikely further drilling will take place at Avshancli-1. Avshancli-2 and Avshancli-3 are not now priority targets.
Gosha geological work
The Gosha contract area is situated close to the border with Armenia. There was no geological exploration in H1 2021 due to the conflict between Armenia and Azerbaijan. However, geological exploration was restarted in H2 2021.
Geological exploration mainly comprised of surface core drilling, together with some outcrop and trench sampling. The surface core drilling resulted in the discovery of a new sub-vertical high gold grade mineralised vein ("Hasan"), after surface mapping suggested the presence of gold at this location.
The Gosha mine was previously thought to consist of two narrow gold veins, zone 13 and zone 5 to the south. Mining has previously taken place from both these veins. Hasan is located immediately south of zone 5 and intersects it at one point. The host rock mostly exhibits silicification and kaolinisation alteration which changes to quartz-haematite alteration in andesite.
During H2 2021, a total of 4,618 metres of core drilling was completed. Bonanza grades of up to 229.5 grammes of gold per tonne were returned, with significant drill intersections as follows:
Hole i.d | Intersection | Weighted average grade | |||
Depth | Downhole Length meters | Gold
g/t | Silver
g/t | ||
From meters | To meters | ||||
21GODDH01 | 65.80 | 69.40 | 3.20 | 53.42 | 5.00 |
66.80 | 67.30 | 0.50 | 229.50 | 5.00 | |
61.00 | 71.00 | 10.00 | 23.24 | 5.00 | |
The new gold vein can be accessed via a short tunnel from the existing tunnelling at Gosha. The vein is currently being evaluated further and mining of the vein planned.
Ordubad geological work
No geological field work was carried out at Ordubad during H2 2021 as the COVID-19 restrictions prevented drill access to the area. A small geological team remained active at the location and geological re-logging of previously drilled core samples continued.
