Name and Location
Zeta underground copper mine project, Botswana.

Client
Discovery Metals Limited (DML).

Project Description
The Zeta underground mine project – a key component of the Boseto copper mine development plan – has total proved and probable ore reserves of 7.3-million tonnes, with a grading of 1.3% copper and 24.5 g/t silver, and total resources of 9.07-million tonnes, with a grading of 1.3% copper and 26.8 g/t silver.

The development plan for the Zeta underground mine will result in the construction of an integrated opencut and underground mine, producing an average 1.5-million tonnes a year – 18 000 t/y copper and 800 000 oz/y silver – over an 11-year period.

A twin-decline development from the Zeta openpit area will provide underground access.

The underground mine will extend over a strike length of 2 km beneath the Zeta openpit, between 150 m and 630 m below surface.

Value
Capital expenditure to first ore production is $26.8-million. The definitive feasibility study (DFS) on the project expects that the development of the mine will be financed using cash flows from the Boseto openpit operations.

Duration
Underground mining is expected to start from the Zeta prospect in 2014, with production expected in 2015.

Latest Developments
DML has been granted government approval for the development of the Zeta underground mine, at the Boseto copper project.

The Ministry of Minerals, Energy and Water Resources has amended the mining licence at Boseto to include the Zeta underground mine.

The establishment of the Zeta underground mine will significantly lengthen the life of the Boseto operation while also providing longer and consistent access to the high quality mineralisation.
