Nexa Reports Equipment Failure at Vazante

October 25, 2019

LUXEMBOURG--(BUSINESS WIRE)--Oct 25, 2019--

Nexa Resources S.A. (“Nexa Resources” or “Nexa” or the “Company”) (NYSE and TSX Symbol: “NEXA”) hereby informs its shareholders and the market in general the occurrence of an equipment failure at the Vazante mine operation in Minas Gerais, Brazil.

During a regular inspection activity, a crack was identified in the trunnion at the discharge side in the primary mill used in the concentration plant. No work accidents nor environmental impacts from this failure were reported. Equipment repair should last about 30 days.

During this period, Vazante mine should operate at 30% of its nominal production capacity and as a result, Nexa expects a production loss of 8 to 10 thousand tons of zinc in concentrate. 2019 production guidance is under review to reflect this temporary loss.

Nexa will keep its shareholders and the market duly informed in a timely manner of any further developments arising from this equipment failure.
