Four areas of interest identified, suggesting further investigation is highly justified
Anglesey Mining plc (AIM: AYM), the UK-based mineral exploration and development company advancing the UK's largest polymetallic Volcanic Massive Sulphide ("VMS") project at the 100% owned Parys Mountain Cu-Zn-Pb-Ag-Au VMS deposit in North Wales, announces the receipt of results for the exploratory geospatial analysis project from Satellite Applications Catapult ("Catapult") and the British Geological Survey ("BGS").
Highlights:
As announced on 26 May 2026, the Company engaged Catapult to provide a preliminary geospatial analysis study as an exploration method for identifying potential VMS extensions in and around the Parys Mountain region.
Catapult, a UK Research & Innovation provider of remote sensing and geospatial services, worked with the BGS, drawing on its extensive deposit-type and earth observation expertise, to produce an integrated analysis of Light Detection and Ranging ("LiDAR"), spectral and geophysical datasets. These non-intrusive methods were used to provide more rapid and less costly indications of subsurface geology and assess the potential for additional exploration targets.
The BGS identified four areas of interest where combinations of geological, geophysical and Earth observation datasets further justify additional exploration. The highlighted areas broadly align, as expected, with those already identified in the Company's ongoing technical reviews, providing additional data to support the analysis and further de-risk costly exploration at Parys Mountain.
