Horsehead Holding Corp. (NASDAQ: ZINC) today issued an update on operations at its Mooresboro, North Carolina zinc production facility. The Company reported that the facility produced over 2,900 tons of zinc metal in June, 2014, a rate of approximately 23% of design capacity which was better than internal projections for the first month of an expected six month ramp up. Zinc feedstock produced from the Company's recycling operations in excess of the requirement for the Mooresboro plant were sold as either zinc calcine or waelz oxide. The Company further announced that the facility will be taking a temporary outage due to the need to repair, upgrade and replace some of the mixing components in a series of tanks. The Company believes this work can be accomplished within approximately two to three weeks and for minimal cost. The Company also reported that the construction of the co-product recovery circuit designed to recover lead and silver is mechanically complete, commissioning has started and is expected to occur for the next few weeks before metal concentrate production begins.

James Hensler, the Company’s President and CEO issued the following statement: “We are pleased by the faster than expected ramp-up during the initial month of operation of Mooresboro. This temporary outage, though not uncommon in start-up situations, represents a minor setback in the short-term but, should result in more reliable and sustainable operations in the long-run.”
