    (1)              Ore tonnes mined in 2016 include
                     902,000 tonnes of supergene ore
                     and 2,741,000 tonnes of primary
                     ore.

    (2)              The supergene phase of the Bisha
                     mine ceased on June 2, 2016.

    (3)              This represents the overall
                     combined zinc recovery from both
                     the copper and zinc flotation
                     circuits. Copper recovery
                     for both circuits averaged 41.2%
                     in Q3 2016 and 60.7% in Q4 2016.

    (4)              The Company as yet has not been
                     able to produce a commercially
                     saleable copper concentrate due
                     to metallurgical
                     challenges when processing the
                     variable primary ore. The by-
                     product revenues from copper,
                     gold and silver in the
                     zinc concentrates have not been
                     material during 2016.

    (5)              The zinc in concentrate inventory
                     at December 31, 2016 was
                     approximately 20.4 million
                     pounds.

2017 Outlook and Guidance

Nevsun is currently completing its annual forecasting process at Bisha where the work on a robust geo-metallurgical resource model and the copper flotation plant metallurgy are ongoing. We expect to provide our 2017 Outlook and update on the resolution to the challenges related to the copper flotation circuit in mid-February 2017.
