Operational Update

Alba Mineral Resources plc (AIM: ALBA), the gold and critical raw materials focused exploration and development company, provides this operational update in respect of the Clogau St David's Gold Mine in Wales ("Clogau" or the "Mine").

Following the completion of the recent phase of underground works at the Mine, the Company is pleased to confirm the resumption of drilling and blasting operations at the Llechfraith Target, Alba's priority gold target at Clogau. An estimated 15 or so tonnes of blast material are in the process of being removed from underground following the first successfully completed blast.
