Nevsun Zinc Expansion Photo Gallery Update-II

  • Footings for Regrind Mill Newr Completion (Dec 2014)

By TesfaNews,

BISHA Mining Share Company (BMSC) is advancing with its zinc expansion project in Eritrea with a target start-up in Q4 2015.

The Bisha Main deposit is a high grade VMS deposit. It is configured in three distinct layered zones – a 35m thick surface gold-silver oxide zone (mined out in mid-2013) immediately overlying a copper enriched supergene zone which itself overlies a primary sulphide zone containing both zinc and copper, which is open to depth.

The Bisha Mine began construction in September 2008 and declared commercial production in February 2011 at a rate of 2Mtpa (million tonns annually). The mine produced low-cost gold-silver dore until mid-2013 when, through a $110 million copper expansion, throughput expanded to 2.4Mtpa and the product switched to copper in concentrate. Later in the mine life flotation capacity will be expanded again to also produce zinc concentrates.
