Anglesey Mining plc announced that assay results have been received for the recently completed drill hole NCZ003. Drill hole NCZ003 was the third hole to be completed from the infill drilling program of the Northern Copper Zone (NCZ) and Garth Daniel Zone (GDZ) at the Company?s Parys Mountain Cu-Zn-Pb-Ag-Au VMS project on the Isle of Anglesey in North West Wales. Consistent both with historical drilling and the recently completed NCZ001 and NCZ002 holes, the assays confirm NCZ003 intersected a significant zone of mineralisation across the NCZ with 90m @ 0.57% CuEq (including internal dilution).

Drill hole NCZ003 was terminated prematurely at a depth of 535m due to a large, potentially fault-related void. The last 6 metres of core prior to the 4m void assayed 1.16% CuEq and coincides with previous high-grade assays from historic drilling. As with the previous two holes in the program, NCZ003 intersected both broad zones of mineralisation and multiple higher-grade zones.

Importantly, the drilling is demonstrating good continuity and further supports the integrity of the geological model and drill targeting, with indications of greater mineralised volumes overall. The third drill hole, NCZ003, concludes the on-site portion of the current exploration and infill drilling program and the company expecting litho-geochemical analysis results, from each of the three holes, to be back from the laboratory in Canada in the coming weeks. Subsequently, on the strength of all the data collected and the interpretation thereof, the Company is targeting a resource update on the NCZ, with the aim of converting a significant portion of the Inferred Resource into the higher confidence Indicated category.

Based on the Joint Ore Reserve Committee (JORC) guidelines, only Indicated and Measured category Mineral Resources can be converted into Ore Reserves. The interpreted outline of the NCZ in the cross-section does not imply an economic outcome, it simply highlights where sulphides have been identified within the Northern Shales with a 0.5% CuEq cut-off. A significant number of the drill holes within this zone have returned consistent zones of higher-grade material, which was a key target of the program.

The recognition of a shear zone along the hanging wall of the NCZ could imply a structural emplacement, or thickening of the sequence within the mine environment and will greatly assist with future targeting and drilling. Importantly, every hole drilled into the interpreted position of the NCZ has intersected broad zones of sulphides; the drilling has demonstrated the predictability of the mineralised zone from the detailed geological model that has been constructed and refined over several years. The most recent drill hole, NCZ003, targeted the up-dip area above historical hole H17A and has provided important additional information relating to the key lithology Rhyolite B ?

the emplacement of this unit is closely associated to the mineralising event. This additional information will now be incorporated into the geological model and the resource block model of the NCZ. Drill hole NCZ003 ended prematurely at a depth of 535m due to faulted ground conditions and the intersection of a 4m void.

The last metre of core prior to the void assayed 1.3% Cu and 1.22% CuEq. The location of the void correlates to the contact position of Rhyolite B and the host northern shale unit, which has traditionally been a zone related to higher grade intersections ? drill hole A15 intersected 1.6m @ 3.7% CuEq approximately 100m up-dip from NCZ003 and NCZ001 intersected 22.0m @ 3.2% CuEq on section 4800mE (200m along strike).
