Announcement PDF RNS Number : 5766E Alba Mineral Resources PLC 31 October 2022 Alba Mineral Resources plc ("Alba" or the "Company") Clogau Gold Mine Operational Update Alba Mineral Resources plc (AIM: ALBA) is pleased to confirm, in respect of its 100 per cent owned Clogau-St David's Gold Project ("Clogau" or the "Project"), the submission of renewed permit applications to dewater the Llechfraith Shaft and associated workings. Situated within the Dolgellau Gold Field in north Wales, United Kingdom, the Project comprises the Clogau Gold Mine (the "Mine"), where Alba has identified a number of high priority gold targets through extensive exploratory drilling in 2020-21, as well as a large number of gold targets and former gold workings outside of the footprint of the Mine, within a total licence area of 106.94 km². Details The Company's primary target within the Mine is the projected Llechfraith Shaft lode extension in the Lower Llechfraith workings, situated below the Llechfraith Adit level. This target was identified through Alba's surface drilling campaigns in 2020 and 2021, by which Alba was able to confirm vein (or lode) continuity up to ~122 m below the existing Lower Llechfraith workings (Fig. 1). In order to gain access to that target, the Company must first dewater the flooded Llechfraith Shaft (Fig. 2). Following the refusal by the competent regulator, Natural Resources Wales ("NRW"), in November 2021 to grant the Company's application to dewater the Llechfraith Shaft, in March 2022 Alba submitted additional data and analysis to the regulator and, following the receipt of further feedback, proceeded to implement an extension to the Company's programme of ecological and species surveys in order to expand the ecological dataset generated during the past 3-4 years. Following the completion of those surveys, analysis of the survey results and their integration into the Company's overall dataset, Alba is pleased to report that it has now submitted to NRW an updated version of its previous, extensive "Report to Inform a Habitat Regulations Assessment", together with renewed applications for a water discharge permit and a European Protected Species licence in respect of the proposed dewatering exercise and subsequent safety and exploratory works. The Company was also pleased to host recently a site visit at Clogau for senior NRW personnel. Further material updates in respect of the permitting process will be provided as and when they become available.
