(Alliance News) - Xtract Resources PLC on Tuesday said sampling of mine tailings at its Kalengwa copper project in Zambia supports previously reported grades.
Shares in Xtract were up 5.2% at 1.24 pence in afternoon trade in London.
Xtract's preliminary sampling in the Kalengwa mine tailings dumps found an average grade of 1.0% copper and 4.4 parts per million of silver.
Executive Chair Colin Bird said: "This is a very pleasing result confirming copper grades in tailings over a large sample population, similar to results reported in archive information. We are currently undertaking metallurgical test work aimed at assessing the optimal method of copper recovery through mineral processing, upgrading or separation at site. Work is continuing at Kalengwa to enhance local infrastructure to facilitate the planned operation.
"We intend in the near term to undertake drilling to assess primary ore potential to the north and south of the former open pit."
More systemic sampling is planned for Kalengwa, aiming to "more accurately define the tailings resource" and metallurgical recovery test work has begun.
Kalengwa was owned by Roan Consolidated Mines Ltd and produced 15,000 tonnes of copper per year between 1970 and 1982.
