About Aripuanã

The Aripuanã project is owned by Mineração Dardanelos Ltda., a joint venture between Nexa (which holds a 62.3% interest), Compañia Minera Milpo S.A.A., which is currently changing its corporate name to Nexa Resources Perú S.A.A., a subsidiary of Nexa (which holds a 7.7% interest) and Mineração Rio Aripuanã Ltda., a subsidiary of Karmin Exploration Inc. (which holds the remaining 30%).

Aripuanã is an underground polymetallic project containing zinc, lead and copper, with an anticipated mine life of 24 years and an expected start of production in 2020. As set out in the preliminary economic assessment (“PEA”), the estimated aggregate capital expenditure required for this project is US$354 million. It is currently estimated that the Aripuanã project, when and if it is fully developed and begins operation, could produce an annual average of approximately 51.0 thousand tonnes of zinc in concentrate, 20.0 thousand tonnes of lead in concentrate, 4.0 thousand tonnes of copper in concentrate and also 1.0 million ounces of silver and 25.0 thousand ounces of gold contained in the zinc, lead and copper concentrates over a 24-year life of mine.

Aripuanã is located in the State of Mato Grosso, Brazil, exhibiting characteristics of a Volcanogenic Massive Sulfide, or VMS. The PEA disclosed the details of the possible development of an operation with 5,000 tpd ore mining and processing capacity.

Outlook

The pre-feasibility study stage was completed during 2017, and Nexa approved the project to move forward to the feasibility study stage. Currently, the feasibility study development (FEL3) has advanced accordingly, reaching 58% of progress at the end of March, 2018 and is expected to be submitted to Nexa’s Board of Directors approval during 2018. In 2017, the exploration program has developed more than 26,600 meter infill drilling focused on mineral resources conversion and identification of mineralized deposits. The project is still pending other applicable licenses and permits in Brazil such as the Installation License (LI) and Operating License (LO).
