n late 2019, Alba drilled a target within the historic Llechfraith mine area. This short drilling campaign successfully intersected shear zone-hosted quartz veins, the known geological setting for all historic gold mining at Clogau, and did so up to 25 metres below the lowest known mined areas, thus confirming the continuity of the structure for at least that distance down-dip of the historic mine workings.In September and October 2020, the Company undertook an extensive underground drilling programme on the Llechfraith level of the mine, the first time to Alba’s knowledge that diamond drilling had ever been carried out underground. Seven drill holes were completed, for over 500 metres of drilling.At the same time, the Company undertook a significant programme of underground bulk sampling, collecting over 36 tonnes of material from several target zones. This material will be processed for its gold content and the results from the underground drilling and bulk sampling will then be incorporated into the geological model to refine the gold targets for follow-up drilling and sampling.A Phase 1 surface drilling programme has been completed, targeting a zone below the Llechfraith mine area. By stepping out the drilling so that the drill collar was set further away from the mine area, the drilling was designed to intersect the quartz vein at a higher, and therefore more favourable, angle to dip. This was successful, given the significant widths of quartz vein which have been intersected; for instance, LL001 intersected a total of 6.48 metres of quartz veins, LL002 a total of 3.65 metres and LL003 a total of 5.7 metres. At its deepest point, drill hole LL010 intersected the lode structure 122 metres below the existing Llechfraith mine workings, almost doubling the depth extent identified previously by LL009 (at 66 metres), with a strike extent of up to 52 metres.Alba’s Phase 1 surface drilling has therefore confirmed the presence of a significant vein system below the deepest previously worked zone at the Llechfraith mine area. Our geological modelling indicates that the total tonnage estimation for the newly identified lode structure is between 24,000 to 27,000 tonnes in the Lower Lode alone.Phase 2 drilling has been completed, The development phase of Clogau has now started as referenced within their recent RNS and podcasts to extract bulk samples from newly identified target zones at minimal cost to Alba
