About this update from Anglesey Mining Plc
[{"type":"text","content":"\n\n \n \n\n\n\n\n Trading SymbolAIM: AYM 4th December 2023 Anglesey Mining plc(“Anglesey” or “the Company”) Parys Mountain – Positive Preliminary Results from Metallurgical Testwork Anglesey Mining plc (AIM:AYM), the UK minerals development company, is pleased to report that it has received preliminary results from the metallurgical testwork on the White Rock and Engine Zones at the Company’s Parys Mountain Cu-Zn-Pb-Ag-Au project, located on the Isle of Anglesey. In June, the Company dispatched a 340kg sample to Grinding Solutions Limited (GSL) comprising a blend of material from both the White Rock and Engine Zones with a combined head-grade of 0.42% Cu, 3.60% Zn, 3.08% Pb, 49g/t Ag and 0.7g/t Au (10.8% ZnEq). The blend was 3.3 (White Rock) to 1.0 (Engine Zone), similar to the contribution that is expected to be delivered from the mine in the early years of production, prior to the Northern Copper Zone commencing. Highlights \tTwo pre-concentration methods were conducted – Dense Media Separation (DMS) undertaken by Pesco and X-Ray Transmission sorting (XRT) completed by TOMRA. One element of the testwork was to determine the optimal process to take forward into the Pre-Feasibility Study. \tBoth methods demonstrated that a successful pre-concentration stage would be applicable with the overall base metals only head-grade increasing from 7.5% ZnEq to 11.4% ZnEq from the DMS (+52%) and 11.7% ZnEq from the XRT (+55%) – results will be updated once the gold and silver numbers are finalised – the precious metals are expected to add 3-4% to the ZnEq grade.
