Anglesey Mining plc provided an update on the Northern Copper Zone (Mineral Resource delineation drilling program at the Parys Mountain Cu-Zn-Pb-Ag-Au VMS project on the Isle of Anglesey in NW Wales. The 2023/2024 exploration drilling campaign has been designed to verify the reliability of historical drill holes and infill gaps in the drilling that will be used to update the Parys Mountain Mineral Resource Estimate. Drill hole NCZ002 was recently completed with a 107m (apparent thickness) zone of visible sulphides identified between 413m - 520m downhole.

The hole was designed as an infill hole between two pierce points from the previous drilling programme undertaken at the site in the 1970s that intersected broad zones of mineralization - 91m grading 0.9% copper equivalent ('CuEq') and 75m grading 0.8% CuEq - both of which reported higher grade zones including 43m grading 1.2% CuEq and 26m grading 1.3% CuEq. Samples from NCZ002 were dispatched to the ALS laboratory in Ireland on 16th February and the results are expected within a few weeks. Based on the encouraging intersection of visible sulphides and the promising assay results from NCZ001 (as detailed in the announcement released by the Company on 19th January 2024), it is anticipated that the assay results will confirm the continuity of the Cu-Zn-Pss-Ag-Au mineralization at Parys Mountain.

Drilling of the third drill hole in this latest programme, NCZ003, has commenced with 200m drilled to date. Key takeaways from the drilling results so far include: Further verification of the existing Parys Mountain geological model. Significant high-grade widths of polymetallic mineralization identified along the contact with thearth Daniel Zone.

Intersect of 22m grading 3.2% CuEq1 recently reported from NCZ001 represents a significant potential upside to the current resource estimate.
