Nevsun plans higher copper throughput

24th September 2010

TORONTO (miningweekly.com) - Vancouver-based Nevsun Resources plans to
design the copper phase of its Bisha project, in Eritrea, at a higher
throughput rate than modelled in the feasibility study, the company revealed
on Thursday.

Nevsun plans to start commissioning the first phase at Bisha by the end of
this year, followed by commercial production in the first quarter of 2011.

The project remains on time and on budget, the firm said.

Nevsun will start off producing gold and silver from oxide ore at Bisha, but
will start copper production in year-three, when it begins processing
supergene ore. Zinc production will start in year six.

Detailed design for the copper phase will start next quarter, and first
production is scheduled in early 2013, Nevsun said on Thursday.

"The company plans to design the copper phase with throughput rates of 20%
to 40% higher than the two-million tons per year modeled in the Bisha
feasibility study," the firm added.

RESERVE GROWTH

Nevsun also said it expects to increase the existing 20-million ton reserve
at Bisha by revising the reserve calculations at updated metals prices and
lower cut-off grades, converting inferred resources below the feasibility
study pit into reserves through infill drilling, and adding to resources and
reserves by definition drilling of the hanging wall copper mineralisation
next to the Bisha deposit.

The company also plans infill drilling at the Harena discovery, which is
nine kilometres south-west of Bisha, to draw up a resource and reserve
estimate.

Nevsun said it expects it can "significantly enhance" the total reserves at
Bisha within the next year.
