Horsehead Update on Mooresboro, NC Facility

June 1, 2015 | By Business Wire News

PITTSBURGH

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 approximately 4,100 tons of zinc metal in May of 2015, compared to 2,600 tons and 2,800 tons in March and April of 2015, respectively. May’s production was the highest monthly production since January of this year. Although production improved, it continues to primarily be paced by the capacity of our process and stormwater treatment system and by intermittent equipment reliability issues.

Jim Hensler, the Company’s President and CEO, issued the following statement: “As noted previously, with the technical assistance of Hatch Associates, we are identifying the causes of the problems that have adversely affected the ramp-up of production, and are confident that these issues can be addressed. We have seen improvement in several areas, which has resulted in an increase in production. In May, we engaged Veolia, a water treatment specialist, to install an interim facility to process stormwater on the site and the unit is now operational, mitigating substantially the risk of a plant shut down caused by significant rainfall. This is the first step in addressing the bottleneck caused by our treatment system. In June, we will be implementing additional process changes to further mitigate this issue. In July, we expect to complete several upgrades discussed during our last earnings call, including installing a bypass around the first solvent extraction unit to reduce the risk of solids accumulation in the settler, increasing cathode inventory to support the production ramp-up schedule and upgrading some key pumps that have had on-going reliability issues. We remain focused on ramping up to our interim goal of 75% of nameplate capacity, which we hope to achieve during the third quarter.”

The Company further commented on hedging activities, reporting that it has locked in the forward zinc price on more than 50% of expected zinc shipments at $1.01/lb for June, 2015 and $1.07/lb for the last six months of 2015.
