(Alliance News) - Europa Metals Ltd said Wednesday it has received the first metallurgical testwork results for the Toral lead, zinc and silver project in Castilla y Leon, Spain, from mining consultancy Wardell Armstrong International.
Locked cycle testing confirmed saleable concentrate quality of the lead, zinc and silver with good grades reported for each concentrate, with 58% lead and 56% zinc. There also was 1,457 parts per million in silver, which was contained in the lead concentrate.
Cycle testing also revealed good recoveries for each metal, with 84% in lead, 71% in zinc, and 90% silver within the lead concentrate.
Based on these findings, Europa Metals will now move on to the next phase of preliminary metallurgical work, which will examine an increased depression of zinc during lead flotation, with the aim of increasing zinc recoveries.
There will also be full testing for deleterious elements and by-products following the testwork. The second phase of testwork is expected to be completed during the first quarter of 2020.
"The lead, zinc and silver grades obtained from Wardell Armstrong's preliminary testwork are, in comparison with the company's peers, very encouraging, particularly in the context of the strong lead recovery. Zinc recovery is in line with the industry average, when compared to producing projects, and the next stage of metallurgy and process design work will focus on optimising zinc retention," said Executive Director Laurence Read.
Shares in Europa Metals - which is based in Perth, Australia - was up 3.6% at 0.026 pence in London, while its Johannesburg shares were untraded on Wednesday, last quoted at ZAR0.01.
