Vast Resources may be able to recommence production at the Manaila Carlibaba polymetallic mine in Romania with the introduction of new technology.

The company has recently tested Tomra's X-Ray Sorting Technology (XRT) on its pre-concentrate ore at the mine's pit. Vast Resources found the technology reduced transportation costs by 55% by minimising the amount of ore to be brought to the processing plant, while also reducing processing costs by minimising unnecessary feed.

The drop in transportation costs would have a substantial impact on the mine's financial performance, Vast Resources said.

Manaila has been on care and maintenance since mid-December 2018.

The mine contains a measured and indicated resource of 3.6 Mt grading 0.93% copper, 0.29% lead, 0.63% zinc, 0.23 g/t gold and 24.9 g/t silver.
