Upgrades to the Gedabek flotation plant and record Gedabek copper production in November

Anglo Asian Mining PLC ("Anglo Asian" or the "Company"), the AIM-listed gold, copper and silver producer focused in Azerbaijan, is pleased to announce it has started production from two new larger filter presses and an associated thickener at its Gedabek flotation plant.

As announced on 16 October 2025, the Company installed a second new filter press at its Gedabek flotation plant. This was part of an upgrade to replace its previous filter presses with two new larger filter presses, which have the capacity to process the higher-grade ore from the new Gilar mine. A new thickener to feed the filter presses has also been installed. The two filter presses and thickener were sourced from Yon Proses & Filtrasyon Teknoloji in Türkiye at a cost of $0.5m and are now fully operational. The installation of the two new filter presses and thickener will increase future copper production.

Construction work on the project to increase the efficiency and productivity of the flotation plant will commence early next year, including the installation of an additional line of Imhoflot Pneumatic rougher and cleaner flotation cells. The Company has already procured the Imhoflot Pneumatic cells which are on site. A contract for $1.6m with Proses Mühendislik A.S. for the installation of the cells has been signed, with the additional line of flotation cells expected to increase the recovery of metals. The flotation plant is currently undergoing preparatory work for the installation of the new cells, including electrical and foundation work. The Company currently has a stockpile of 53,190 tonnes of Gilar ore containing 1.8 grammes per tonne of gold and 3.58 per cent. of copper, which will be processed next year through the expanded plant.

The recent modifications to the flotation plant resulted in November being a record month for the production of copper at Gedabek. Total copper production from flotation and SART was 688 tonnes.

Stephen Westhead, Vice President of Anglo Asian, commented:

"Since we brought the new Gilar mine into production in May 2025, there has been a bottleneck at the filter presses due to the ore grades being higher than the forecast average. These upgrades to our flotation plant enable us to efficiently process this ore variability, which is particularly valuable to Anglo Asian considering global copper demand. This upgrade was completed on time and on budget, and as a result has enabled us to deliver our highest ever monthly copper production.

"These are exciting times for Anglo Asian, and we look forward to continuing to execute our growth strategy at pace."
