Cold-Commissioning Underway at Tavsan

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 cold-commissioning of the processing plant at the Tavsan Mine ("Tavsan" or "the Project") in Türkiye. The Project is operated by Zenit Madencilik San. ve Tic. A.S. ("Zenit"), in partnership with Proccea Construction Co. and Ozaltin Holding A.S., and is 23.5% owned by Ariana.

Highlights:

• Cold-commissioning of the processing plant at Tavsan has commenced and will be completed in stages through June 2025, following recent connection to grid power.
• Heap-leach pads are nearing completion, with first ore loading expected from late June; approximately a year of full ore production remains stockpiled ready for loading.
• Tavsan processing plant is expected to be fully operational from July, with gold production from the heap-leach underway.
• Auxiliary solar power project was recently approved for a 2,555kW system, final planning and installation of which will commence immediately.
• Resource and exploration drilling programme ongoing, having completed 3,700m of an up to 15,000m programme and testing the potential for increases in the life of mine.
• Kerim Sener, Managing Director, commented:

"After several months of a monumental effort from the Zenit team and its contractors, the latest developments at Tavsan are exceptional. The connection to grid power remained outstanding until recently, which has now enabled the commissioning of the processing plant to commence. Work on the heap-leach pads, which had been impeded due to inclement weather conditions, has accelerated rapidly since the onset of warmer and somewhat drier conditions from April and is currently on track for completion later in June.

"A notable new development has been the recent approval of a significant solar power project for the mine. This will not only help reduce operational costs over the life of mine but will also contribute to reducing the power demand from the grid, enhancing the environmental credentials of the operation. Even longer term, it will make a sustainable contribution to the development of the area.

"This will be our first heap-leach operation in Türkiye, which, by operating in parallel with the Kiziltepe CIL processing plant, provides Zenit with a large degree of operational flexibility. Our biggest advantage is that Zenit has about a year's worth of ore production ready for loading on the heap-leach pads at grades ranging from 1.2 to 0.7 g/t Au. Accordingly, we look forward to achieving the first gold pour from the Tavsan processing plant this summer."
