PT Amman Mineral Nusa Tenggara (AMNT), a subsidiary of PT Amman Mineral Internasional Tbk, has successfully secured a crucial copper concentrate export recommendation from Indonesia’s Ministry of Energy and Mineral Resources (ESDM). This vital export permit, authorizing the shipment of 480,000 dry metric tons (dmt), will be valid for a six-month period, commencing on October 31, 2025, and extending through April 2026.
This significant recommendation serves as an essential foundation, paving the way for the Ministry of Trade to issue the official Copper Concentrate Export Approval Letter (SPE) for AMNT.
The granting of this export authorization is directly linked to a force majeure event experienced at the company’s processing and refining facility, its smelter. Rachmat Makkasau, President Director of AMNT, elaborated that the smelter temporarily ceased operations in July and August 2025 due to critical repairs on its Flash Converting Furnace and Sulfuric Acid Plant units.
“This damage was purely beyond our control, unintentional, and unavoidable,” stated Rachmat in an official release on Saturday, November 1. “AMNT’s smelter operations were compelled to a temporary halt to prevent more severe damage and mitigate risks to occupational safety.”
Repairs to Extend Until 2026
Rachmat further explained that the rectification of these primary smelter components is highly complex and necessitates a comprehensive approach. This intricate repair process is projected to continue until the first half of 2026.
“Throughout the repair period, we are maintaining partial operations with careful production increases, ensuring that safety aspects are never compromised,” he added, emphasizing the company’s commitment.
With the resumption of copper concentrate export sales, which had been suspended since early 2025, Amman Mineral is diligently managing its concentrate storage warehouses to prevent any overcapacity.
This strategic measure ensures that mining operations can proceed according to schedule, simultaneously upholding the company’s fiscal contribution to both the national and regional economies.
According to its 9M 2025 performance report, AMNT aims to produce 430,000 dmt of copper concentrate in 2025. This production is expected to yield approximately 228 million pounds of copper and 90,000 ounces of gold. The target strategically accounts for production derived from both existing stockpiles and lower-grade fresh ore from Phase 8 mining operations.
Current mining activities remain focused on overburden stripping within this phase. In addition to the 2025 production target, AMMAN also reported an impressive inventory of 190,000 dmt by the end of 2024.
As of September 30, 2025, concentrate production had reached 310,143 dmt, with 273,506 dmt already fed into the smelter facility. The total concentrate inventory at the end of September 2025 stood at 226,637 dmt. A portion of this inventory is earmarked for export, while the remainder will be processed at the smelter as facility repairs advance.
“These developments signify a crucial phase towards the full recovery of our smelter operations, underscoring AMNT’s unwavering commitment to fostering sustainable growth and delivering long-term value,” Rachmat concluded.
Summary
PT Amman Mineral Nusa Tenggara (AMNT) telah berhasil memperoleh rekomendasi ekspor konsentrat tembaga dari Kementerian Energi dan Sumber Daya Mineral Indonesia. Izin ekspor penting ini, yang mengizinkan pengiriman 480.000 metrik ton kering, akan berlaku selama enam bulan, mulai 31 Oktober 2025 hingga April 2026, dan membuka jalan bagi Kementerian Perdagangan untuk menerbitkan Surat Persetujuan Ekspor resmi. Otorisasi ini terkait langsung dengan peristiwa *force majeure* di fasilitas pengolahan dan pemurnian (smelter) perusahaan, yang menghentikan sementara operasional pada Juli-Agustus 2025 untuk perbaikan kritis unit *Flash Converting Furnace* dan *Sulfuric Acid Plant*. Perbaikan yang kompleks ini diperkirakan akan berlanjut hingga paruh pertama tahun 2026.
Dengan dimulainya kembali penjualan ekspor konsentrat tembaga, yang sempat ditangguhkan sejak awal 2025, Amman Mineral dapat mengelola gudang penyimpanannya untuk mencegah kelebihan kapasitas. Selama periode perbaikan, AMNT tetap menjalankan operasional parsial dengan peningkatan produksi yang hati-hati, dengan mengutamakan aspek keselamatan. Untuk tahun 2025, AMNT menargetkan produksi 430.000 metrik ton kering konsentrat tembaga, menghasilkan sekitar 228 juta *pound* tembaga dan 90.000 *ounce* emas. Sebagian dari inventaris konsentrat saat ini sebesar 226.637 metrik ton kering akan diekspor, sementara sisanya akan diproses di smelter seiring kemajuan perbaikan fasilitas, menunjukkan fase krusial menuju pemulihan penuh operasional smelter.
