Overview

PT Amman Mineral Internasional Tbk (AMMAN) is a holding company that conducts exploration, development, mining, processing, smelting and refining operations in Indonesia. Its subsidiary is described as one of the largest copper and gold producers in Indonesia, known for operating the Batu Hijau mine and developing the Elang project on the island of Sumbawa.

History

According to AMMAN's historical milestones, PT Newmont Nusa Tenggara (NNT) discovered gold and copper mineralization in Sumbawa Island in 1990, which subsequently developed into the Batu Hijau mine in 2000 and the Elang development project. Batu Hijau started its production and shipment of copper and gold concentrate in 2000, followed by Mining Phase 1-6 at Batu Hijau from 2000 to 2016. In 2016, AMMAN acquired PT Newmont Nusa Tenggara (NNT), which subsequently changed its name to Amman Mineral Nusa Tenggara (AMNT), and became the sole operator of the Batu Hijau mine and the Elang development project. In 2017, AMNT converted CoW to IUPK-OP along with receiving a concentrate export permit; AMMAN acquired significant shares in MacMahon Holdings Limited, a leading Australian mining contractor listed on the Australian Securities Exchange (ASX); and AMNT redesigned and accelerated the Phase 7 pit cutback under a new mining plan. In 2019, Amman Mineral Industri (AMIN) acquired a 145-hectare site for a smelter project in Benete and completed its Front-End Engineering Design (FEED); AMNT significantly improved the quality of tailings and minimized environmental impacts from deep-sea tailings placement (DSTP); and AMNT commenced a feasibility study on Batu Hijau Phase 8 and a feasibility study on the Elang project. In 2020, AMNT started production from Phase 7 fresh ore, three months ahead of schedule; AMMAN completed scoping, pre-feasibility, and feasibility studies on the Elang project; AMNT revised its Phase 8 design, increasing Batu Hijau's reserves from 314 Mt to 460 Mt; and AMNT received the Aditama Trophy for Environmental Management and the Utama Award for Mineral Conservation from the 2020 Good Mining Practices (GMP) Awards, held by the Ministry of Energy and Mineral Resources.
