GABORONE, Dec. 28 (Xinhua) -- Australian miner Discovery Metals has resumed normal development of its Zeta open pit at the Boseto copper project in northwestern Botswana after Botswana government lifted a restriction imposed late November.
Discovery Metals announced in an statement on Friday that the resumption comes after the Botswana Department of Mines, Minerals, Energy and Water Resources accepted the company's geotechnical report and lifted temporary restrictions preventing deepening of the pit.
The restriction, imposed in late November, was the result of a small localized failure of a section of an interim hanging wall, although not cause any fatality.
"With the resumption of normal pit development, mining of sulphide ores at the base of the pit may recommence, enabling supply of higher grade material to the mill," said the company.
The slope failure incident at Boseto is the third mine incidents this year in Botswana following similar incidents at Jwaneng diamond mine and Ghaghoo diamond mine, which resulted in one and two fatalities respectively.
Discovery Metals focused on the emerging Kalahari Copperbelt in north-west Botswana. The Company is a copper producer at its 100 percent owned Boseto Copper Project.
The Kalahari Copperbelt sediment-hosted mineralization of the Boseto copper project is similar in style to the well-known and large deposits of the Central African Copperbelt of Zambia and the Democratic Republic of the Congo. Discovery Metals has prospecting licences covering 11,872 squire kilometers along the Kalahari Copperbelt.
