Health & Safety

PTNNT Named Safest Mining Company

Tambang magazine named PT Newmont Nusa Tenggara (PTNNT) operation as "The Best Mining Company for Health and Safety" in Indonesia for the outstanding occupational, health and safety (OHS) programs and performance.

Previously, the Indonesia Department of Energy and Mineral Resources presented our mine with its Aditama Award for the same OHS program. With several thousand employees, PTNNT is recognized as one of the largest mining companies with the best safety performance in not only Indonesia, but also the world.

For example, to protect the welfare of our employees and the nearby community, we installed 10 tsunami-warning sirens near beaches and villages surrounding our mine, since the coastal area is prone to tsunami threats. In 1977, the southern region of Sumbawa Island was hit by a tsunami, which left many casualties. The sirens have a hearing radius of one to two miles (1,500 to 3,400 meters), and are connected to a central control system operated by mine security.

Managing Malaria

Malaria is a parasitic disease spread by mosquitoes that is prevalent in areas of Africa, Asia and South America. People with malaria often experience fever, chills and flu-like illness. Left untreated, they may develop severe complications and die. In some African countries, malaria is one of the leading causes of community illness and death, especially in young children and pregnant women.

Newmont partners with the International SOS to reduce the incidence of malaria at mine sites in Indonesia and Ghana. The malaria-management programs include mosquito eradication strategies, personal protection, behavior modifications measures, and prompt diagnosis and treatment.

At our Batu Hijau operation in Indonesia, we reduced the incidence of malaria in the community from 80 percent in 1998 to an all-time low of less than 1 percent in 2003. Today, incidence remains less than 2 percent.
