Manaila Polymetallic Mine Update

Vast Resources plc “Vast”, the AIM-listed mining company, is pleased to update the market on developments at its Manaila Polymetallic Mine (‘Manaila’) located in northern Romania.

The Company continues to evaluate the recommencement of production at Manaila and as part of this process, the Company has been working with TOMRA to assess the suitability of X-Ray Sorting Technology (‘XRT’) to optimise the mine’s production profile. The assessment demonstrated that by installing an XRT machine at the plant to pre concentrate ore at the pit, the technology would be highly effective for three main reasons:

  1. a reduction in transportation costs as improved mass reduction would significantly reduce the material being transported from the mine to the processing plant

  2. a reduction in processing costs due to reducing the throughput at the plant

  3. higher-grade product being delivered to the plant.

It is anticipated that processing and transportation costs could be reduced by up to 55%. This cost reduction could have a dramatic impact on the mine’s financial performance.

Samples from both types of mineralisation at Manaila, massive sulphide and disseminated sulphide, were sent to the TOMRA Test Centre in Wedel, Germany, to ascertain improved mass reduction and grade upgrade potential. Both mineralisation types showed amenability to the XRT process with metal content recovery on the massive sulphides at 95.4% for copper, 93.6% for lead and 95.2% for zinc in 71% of the mass. The disseminated sulphides returned a metal content recovery of 84.2% for copper, 67.2% for lead and 84.4% for zinc in 35% of the mass.

The combined results show that 93.1% of copper, 82.2% of lead and 92.4% of zinc metal could be recovered in 45% of the mass when mining the polymetallic ore on a ratio of 3 tonnes disseminated sulphide to 1 tonne of massive sulphide, being the typical historical ratio of mining at Manaila.

Please note that the samples were derived from accessible areas of the open pit which is currently on care and maintenance and as such is not a direct correlation to the mineral resource previously disclosed.

Andrew Prelea, Chief Executive Officer of the Vast Resources plc, commented:

“These results, coupled with the strong recovery in commodities prices this year, highlight Manaila’s position as a commercially attractive project alongside our Baita Plai Polymetallic Mine. These results clearly underpin our view that Manaila is economically viable, and the management team are considering various mine plan scenarios of bringing Manaila back into production. It is our preference to secure the required funding via non-equity linked sources and we will provide further updates to the market in due course.”
