OPERATIONAL UPDATE: TAVSAN

Heap-leach pads complete, hot-commissioning underway

Operational status expected from late July

Ariana Resources plc ("Ariana" or "the Company"), the AIM-listed mineral exploration and development company with gold project interests in Africa and Europe, is pleased to announce the commencement of hot-commissioning of the processing plant at the Tavsan Mine ("Tavsan" or "the Project") in Türkiye, in which Ariana has a 23.5% interest.  This is an important step towards commencement of gold processing operations at Tavsan, the Company's second operating gold mine in Türkiye. 

Highlights:

·    Tavsan Mine is expected to achieve operational status from late July 2025, ready for the commencement of gold production from the heap-leach. 

·    Heap-leach pads are completed, with overliner aggregate currently being laid ahead of ore loading, which will follow the conclusion of statutory government inspections.

·    Hot-commissioning of the crushing and screening plants and cold-commissioning of the agglomerator is complete.

·    Approximately a year of full ore production remains stockpiled ready for loading, with crushing and screening of this material now underway.

·    Overland conveyors installed with their liners and with testing due to commence imminently.

·    Testing of the Adsorption-Desorption-Recovery ("ADR") system underway, with pumps being installed for the pregnant and barren ponds.

·    A second water well to ensure adequate water availability for the operation is being drilled to a maximum depth of 500m (currently at 200m).

·    Resource and exploration drilling programme ongoing, having completed over 6,000m of an up to 15,000m programme and testing the potential for increases in the life of mine.

Dr. Kerim Sener, Managing Director, commented:

"It is a pleasure to report further substantial progress over the past month at the Tavsan mine site.  The Tavsan operation is nearing final commissioning ahead of ore loading onto the heap-leach pad, which is expected from later this month.  The Zenit team is working around the clock to ensure that all remaining system tests are completed on the plant and heap-leach areas ahead of statutory government inspections, before the operation proceeds to production.  Meanwhile, high-grade ore continues to be prioritised for processing through the CIL plant at Kiziltepe, while we prepare for the processing of the stockpile of heap-leachable ore on site, ready for loading onto the pads.

"We are very much looking forward to achieving the first gold pour from the Tavsan mine, enabling the first in-situ gold production from our second mine in Türkiye.  The amount of work completed in recent months and the level of professionalism of the Zenit team and its contractors are nothing short of extraordinary.  We congratulate the team on their collective efforts and wish them a successful start to heap-leach operations at Tavsan."
