Anglesey Advances Resource Growth Upside at Parys Mountain
Anglesey Mining plc (AIM: AYM), the UK-based mineral exploration and development
company and the 100% owner of the Parys Mountain Cu-Zn-Pb-Ag-Au VMS project
("Parys Mt.") in Anglesey, North Wales, is pleased to announce a strategic
operations update.
Highlights
· Appointment of two geologists: Principal and Exploration
· Commencement of review of Mineral Resource Estimate ("MRE") update
· Delineation of further exploration targets
· Reconciliation of historical geological data, geophysics and geo-metallurgy
· Previously proposed hydro scheme will not proceed
The Company recently appointed a Principal Geologist to help spearhead the
review of all historical data at Parys Mt., including core log assays, which
have not been incorporated in the previous MRE from 2023. Older drill core will
also be re-evaluated for potential incorporation into an updated MRE model.
Significant work has already commenced in this regard, and an update will be
provided in due course. In addition, an Exploration Geologist has joined the
team at Parys Mt. to assist with the archiving of historic geological data and
to oversee the systematic exploration efforts. The work is already underway to
help provide efficiency in the oversight of data analysis and continuity going
forward.
Current initial evaluations of historic drill core and underground sampling
analysis clearly demonstrate the enormity of the contained data. Cataloguing
this data into a user-friendly format will be instrumental for the systematic
success of the Parys Mt. project. The amount of data recovered thus far
demonstrates an opportunity to showcase Parys Mt. through improved data
collation.
Exploration efforts are continuing; the preliminary results of our Phase-1 aero
-magnetic programme recently undertaken have indicated anomalies consistent with
VMS deposits, which will warrant ground-based follow-up work. A follow-up aero
-geophysics programme is planned to extend the coverage area outside the
confines of our Phase-1 programme. In addition, our previously reported
Geospatial Exploration programme is nearing completion, and the upcoming results
will incorporate the aero-magnetic findings. This programme will continue to
target further areas of interest.
Recently, our Executive Chairman, Jim Williams, was invited for a preliminary
meeting with the recently appointed First Minister of Wales and Member of the
Senedd. This meeting was constructive, and we envisage further dialogue.
The current management team have further evaluated the previous proposed high
-density hydro initiative as a source for power generation and concluded the
benefit is not worth any further financial commitment or management time.
Furthermore, this initiative would not align with the flagship project of Parys
Mt., which is outlined to be a mining operation, and the only common critical
path would entail the dewatering of the Morris shaft. Management has agreed not
to proceed with this previous proposal. Anglesey has the facility to purchase
green energy from local suppliers, which generate electrical power from both
wind turbines and solar panels, which are abundant on the Isle of Anglesey.
Andrew Fulton, Chief Executive Officer of Anglesey, commented:
"I am already pleasantly surprised with the huge upside potential of Parys
Mountain, the UK's largest polymetallic asset, after having been in the role for
just over one month. Our recent appointments of two geologists have already
started reviewing the large amount of archived data, and now the ability to
transform this data into a meaningful interpretation is gathering momentum.
"I am very experienced with the UK mining industry, having been involved with
significant and successful developments in the UK. With my expertise, my
ambition is to develop Parys Mountain into a flourishing mining operation. Metal
prices, particularly copper, gold and zinc, have been on a general upward
trajectory in recent times, which we believe has given the UK a mandate to be
less reliant on importing certain metals. This will become the foundation on
which we will drive our strategic plans."
