Final assay results from Parys Mountain 2022 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 announcements on 14(th) June and 15(th) July 2022 regarding
assay results, Anglesey is now pleased to announce that the final round of
assay results have been received from the 2022 infill drilling programme at
Parys Mountain.
Parys Mountain Cu-Zn-Pb-Ag-Au Project
* The final two holes of the programme recorded multiple broad intercepts and
continue to highlight that the White Rock and Engine Zones represent an
extensive mineralised system.
* Significant intersections include: * Hole WD-24 from 239.4m - 1.5m at 1.4%
Cu, 9.7% Zn, 6.2% Pb, 187g/t Ag & 2.7g/t Au (7.1% CuEq/19.9% ZnEq)(1)
* Hole WD-24 from 262.94m - 28.96m at 3.3% Zn, 1.7% Pb, 0.5% Cu, 71g/t Ag &
0.9g/t Au (2.3% CuEq/6.5% ZnEq)(1) including: * 13m at 5.2% Zn, 2.6% Pb, 0.6%
Cu, 100g/t Ag & 1.6g/t Au (3.6% CuEq/10.1% ZnEq)(1)
* 5.1m at 4.0% Zn, 2.3% Pb, 0.9% Cu, 118g/t Ag & 0.4g/t Au (3.0% CuEq/8.4%
ZnEq)(1)
* Hole WD-23 from 93m - 143.92m at 0.9% Zn, 0.5% Pb, 0.2% Cu, 9g/t Ag & 0.2g/t
Au (0.6% CuEq/1.6% ZnEq)(1) including: * 7.1m at 3.5% Zn, 2.7% Pb, 0.5% Cu,
25g/t Ag & 0.2g/t Au (2.1% CuEq/5.9% ZnEq)(1)
* With all assays now received, the Company will select samples from the 10
drill holes for the metallurgical testwork programme. This will provide a
trade-off study between the Dense Media Separation (DMS) and X-Ray
Transmission (XRT) ore sorting pre-concentration methods. Historical DMS
studies from 2007 demonstrated a 40% mass rejection of waste with only 3-5%
metal losses. The metallurgical programme will also include testwork on
potential tailings to feed into the next round of tailings management design
work.
* Anglesey will immediately commence an update to the Mineral Resource
Estimate for the White Rock and Engine Zones to incorporate the additional
information from the recent infill drill programme.
* In other ongoing workstreams at Parys Mountain: * Conceptual tailings
management studies have demonstrated that the Parys Mountain site has
sufficient capacity to hold all the tailings that would be produced under the
largest production scenario of 3,000tpd, as detailed in the Preliminary
Economic Assessment published in January 2021. The Company plans to embark on
the initial tailings design programme subsequent to receiving the
metallurgical testwork on the expected tailings product.
* The geotechnical work on the White Rock deposit is ongoing. Our consultant,
Knight Piésold, has collected all the data to assess the rock mass
characteristics and complete basic ground model development. Once complete,
this data will feed into the mine design to maximise mining spans and assess
ground control requirements for underground mining.
* Permitting and planning activities have continued after further
consultations with the North Wales Minerals and Waste Planning Service. The
next steps for this process include the scoping of the Environmental Impact &
Social Assessment report. These activities remain ongoing.
Jo Battershill, Chief Executive of Anglesey Mining, commented: “With the
final encouraging assay results now received, we can move onto the next round
of workstreams for Parys Mountain. As previously highlighted, core will be
sent to Grinding Solutions to conduct pre-concentration studies on
representative samples from areas that are likely to be mined. We believe that
the ability to selectively remove the unmineralized material would have a
significant positive economic impact for the ongoing development studies.”
“Additionally, the intention of the recent drilling programme was to
increase the 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 have now all been received, we will look to update the Mineral
Resource Estimate.”
“In other areas, we continue to progress the surveys required for the
environmental baseline work and we will soon commence the initial design work
for the tailings management facility. Both aspects are critical to progressing
Parys Mountain through the permitting phase. Meanwhile, work on advancing the
Northern Copper Zone is progressing well. As part of this process,
Anglesey’s team has reviewed the historical drilling and resource model of
the Northern Copper Zone with the aim of identifying prospective areas that
would optimise future drilling programmes. We will focus on the zones that
could have the most immediate impact on the mine design and production
schedule. Historical drilling and internal reviews would suggest that the
Northern Copper Zone could be significantly larger than the current resource
estimate suggests, but additional drilling will be required to confirm this
potential.”

(1) Zinc Equivalent (ZnEq %) = Zn grade % * Zn Recovery + (Cu grade % * Cu
Recovery * (Cu price $/t / Zn price $/t)) + (Pb grade % * Pb Recovery * (Pb
price $/t / Zn price $/t)) + (Ag grade g/t / 31.103 * Ag recovery * (Ag price
$/oz / Zn price $/t)) + (Au grade g/t / 31.103 * Au recovery * (Au price $/oz
/ Zn price $/t))
Zn equivalent calculated using following commodity prices: Zn – US$1.25/lb,
Cu – US$3.50/lb, Pb – US$1.00/lb, Ag – US$22.50/oz & Au – US$1750/oz
Zn Equivalent calculated using following recovery assumptions for White Rock
deposit: Zn – 82%, Cu – 48%, Pb – 78%, Ag – 70% & Au -50%
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.
