Indonesia to give Amman Mineral 400,000t copper concentrate export quota

Indonesia will give copper miner Amman Mineral Internasional an export quota of about 400,000 metric tons for its concentrate that will be valid for six months, local media reported on Thursday, citing an energy ministry official.

Indonesia banned exports of copper concentrate and other raw minerals from mid-2023 to boost the domestic metal processing industry, though the government let Amman continue exporting until December last year after commissioning a new smelter in West Nusa Tenggara province.

But Amman temporarily stopped operations at the facility this year due to damage on its flash converting furnace and sulfuric acid plant units, it said, requesting another export permit from the government.

The quota of about 400,000 tons quota was reported by several local media outlets, quoting remarks made on Wednesday by energy ministry official Tri Winarno.

Both Tri and an energy ministry spokesperson did not immediately respond to requests for comment. An Amman spokesperson said the firm could not provide comment.

In a Thursday stock exchange filing, Amman said the smelter was now operating partially while it was being fixed, with completion targeted in the first half of 2026.

Amman said in the filing that it had submitted a request to export concentrate, without mentioning the volume.

Amman reported in the filing that its concentrate output was at 310,143 tons between January and September 2025, a 51% drop from the same period last year.

Amman said its copper cathode output in the same period was 41,052 tons, while copper cathode sales reached 39,805 tons.
