Anglesey Mining Gives Update on Northern Copper and Garth Daniel Zone

At Anglesey Mining plc’s Parys Mountain property, the Northern Copper Zone (NCZ) has shown significant mineralization, which has been traced through historical mining and diamond drilling over a 1.2-kilometer strike length. The NCZ boasts an inferred resource of 9.38 million tonnes containing 1.27% copper, 0.38% zinc, 0.24% lead, 5 grams per tonne of silver, and 0.1 grams per tonne of gold. Additionally, the Garth Daniel Zone (GDZ) at the property has an inferred resource of 0.34 million tonnes with higher concentrations, including 1.89% copper, 5.78% zinc, 2.76% lead, 66 grams per tonne of silver, and 0.1 grams per tonne of gold.

The 2023-2024 drilling program successfully encountered significant mineralization across all three boreholes (NCZ001, NCZ002, and NCZ003). Each hole intersected both extensive zones of mineral content and several higher-grade pockets, indicating a promising outlook for further exploration and potential resource development.The results from these sections demonstrate good continuity, further supporting the integrity of the geological model and drill targeting. The findings indicate potential for greater mineralized volumes than previously estimated, reinforcing the prospects for the Northern Copper Zone (NCZ).

Anglesey Mining has recently received detailed geochemical analysis results from Activation Laboratories in Canada, which have significantly improved the understanding of the ore horizons within the Parys Mountain property. These results have refined the stratigraphic positioning of the main ore zones, enabling more accurate geological correlations across the entire property. While work is ongoing, the latest drilling has confirmed that the intersected rocks and styles of alteration and mineralization align with those observed in previous drilling campaigns, which were also subjected to litho-geochemical analysis.

A detailed understanding of the lithology from the recently completed holes will enable the construction of a new structural geological model. This model will incorporate data from all previous exploration drilling in both the NCZ and the Garth Daniel Zone (GDZ). The anticipated model will offer more precision than the current one and could provide valuable insights into the controls and distribution of mineralized zones. Once completed, it is expected to be applicable on a wider scale and play a critical role in future mine planning efforts.

Rob Marsden, CEO of Anglesey Mining, emphasized the importance of thoroughly analyzing and contextualizing the data from the 2023-2024 drilling campaign at Parys Mountain. He expressed satisfaction with how the latest dataset not only supports but also enhances the previous geological interpretations of the deposit. This underscores the value of the current work being done to deepen the understanding of the site's mineralization and improve future exploration and development strategies.

Anglesey Mining is advancing the development of its 100% owned Parys Mountain deposit in North Wales, UK. This volcanogenic massive sulfide (VMS) deposit contains significant quantities of copper (Cu), zinc (Zn), lead (Pb), silver (Ag), and gold (Au). The reported resources include 5.3 million tonnes in the Measured and Indicated categories with a combined base metal grade of over 4.0%, and an additional 10.8 million tonnes in the Inferred category with a combined base metal grade of over 2.5%.
