(“Anglesey” or “the Company”)
Further strong assay results from Parys Mountain drilling
Anglesey Mining plc (AIM:AYM), the UK minerals development company, continues
to advance work programmes at both its Parys Mountain Cu-Zn-Pb-Ag-Au VMS
project on the Isle of Anglesey in North West Wales and its Grängesberg iron
ore project in Sweden.
Following the announcement released by the Company on 14(th) June regarding
initial assay results, Anglesey is now pleased to announce that the second
round of assay results have been received from an additional three holes of
the recent infill drilling programme at Parys Mountain.
Parys Mountain Cu-Zn-Pb-Ag-Au Project
* All three holes recorded multiple broad intercepts and continue to highlight
that the White Rock deposit is an extensive mineralised system.
* Significant intersections include: * 9.0m at 4.9% Zn, 3.1% Pb, 0.2% Cu,
24g/t Ag & 0.3g/t Au (WD-20 from 133.5m) including * 6.0m at 6.3% Zn, 4.0% Pb,
0.2% Cu, 25g/t Ag & 0.3g/t Au
* 11.0m at 3.7% Zn, 2.3% Pb, 0.2% Cu, 27g/t Ag & 0.3g/t Au (WD-20 from 146.5m)
including * 4.0m at 5.6% Zn, 3.8% Pb, 0.3% Cu, 43g/t Ag & 0.3g/t Au
* 1.04m at 8.5% Zn, 5.3% Pb, 1.0% Cu, 27g/t Ag & 0.3g/t Au (WD-21 from 195m)
* 12.74m at 3.7% Zn, 1.9% Pb, 0.2% Cu, 22g/t Ag & 0.6g/t Au (WD-21 from
204.5m)
* 5.4m at 3.3% Zn, 1.8% Pb, 0.2% Cu, 53g/t Ag & 0.6g/t Au (WD-22 from 147.3m)
* 12.8m at 3.0% Zn, 1.3% Pb, 0.2% Cu, 51g/t Ag & 0.5g/t Au (WD-22 from 167.9m)
including * 4.2m at 5.6% Zn, 2.5% Pb, 0.4% Cu, 95g/t Ag & 0.8g/t Au
* The final two holes of the programme are being logged for additional data to
assist with geotechnical domain modelling, which will be utilised in the
underground mine design optimisation. Once logged, they will be sampled and
dispatched for assaying.
* Over the next month, samples will be selected for the metallurgical testwork
programme, which will include both Dense Media Separation and XRT ore sorting
pre-concentration studies. Historical pre-concentration studies have
demonstrated a 40% mass rejection of waste with only 3-5% metal losses.
Jo Battershill, Chief Executive of Anglesey Mining, commented: “The
intention of this programme was to increase the amount of resources in the
Indicated category for the White Rock deposit, which stood at 4.7Mt, or 79%,
prior to commencing the drilling. Given the results, we are very confident
that a significant portion of the currently Inferred material will be upgraded
to Indicated. The importance of this should not be discounted given Inferred
resources are not permitted to be included in reserve estimates.”
“The next stage of this programme is to conduct pre-concentration studies on
representative samples from areas that are likely to be mined. The ability to
selectively remove the unmineralized material would have significant economic
ramifications for the development studies.”
“In other areas, we continue to progress the ecological surveys required for
the environmental baseline work and we will soon commence the initial tailings
management and design studies. Both of these aspects are critical to
progressing Parys Mountain through the permitting phase. Meanwhile, work on
planning the Northern Copper Zone infill drilling programme, scheduled for
later in the year, is progressing. As part of this process, the team is
currently reviewing the historical drilling and resource model with the aim of
optimising the infill drilling in the zones closest to surface as these could
have the most immediate impact on the mine design and production schedule.”

Sample analysis and QA/QC
All samples generated from the drilling were dispatched to ALS Loughrea.
Samples were analysed for multi-element data analysis using their ME-ICP61
package, which includes Ag, Cu, Pb and Zn. The samples were also assayed for
gold using their Au-AA23 analysis package. Overlimit assays were then analysed
using their Ag-OG62, Cu-OG62, Pb-OG62, Zn-OG62 and ME-OG62 analysis packages.
For QA/QC purposes, Anglesey Mining used the industry standard of inserting 5%
Certified Reference Material (CRM) samples, 2.5% Certified Blank Samples
(Blanks) and 5% duplicate samples at source. The CRMs were sourced from
Geostats Pty Ltd, Ore Research & Exploration Pty Ltd, OREAS and Natural
Resources Canada.
