News  April 22, 2021 - The smelter construction carried out by PT Amman Mineral Nusa Tenggara has only reached 26.68 percent and is predicted to be completed in June 2023. According to AMNT, the delay in completing the smelter cannot be separated from the impact of the Covid-19 pandemic, which requires rescheduling the smelter project. PT AMNT President Director Rahmat Makasau explained that at the end of April 2021, the company will establish a smelter development division.  "Our target is that in June 2021 construction activities will begin and in the fourth quarter the construction phase will begin," explained Rahmat through a press release, Thursday.  In addition to building a smelter, AMNT is also building a precious metal refining facility (PRM) whose construction progress is only 28.58 percent. The operation of the smelter and metal refining facility is planned to be realized in early 2024. West Sumbawa Regent W. Syafirin asked AMNT to remain committed to completing the smelter construction in West Sumbawa.  www.ekonomi.bisnis.com

April 14, 2021 - PT Amman Mineral Nusa Tenggara (AMNT), a business unit of PT Medco Energi Internasional Tbk (MEDC) in the mining sector, has reduced the input capacity of copper concentrate in the smelter project which is currently being built in Benete, West Sumbawa Regency, West Nusa Tenggara. (NTB).  Initially, the targeted capacity was 1.3 million tons per year, but now the target has been lowered to 900 thousand tons per year.  President Director of PT Amman Mineral Nusa Tenggara (AMNT) Rachmat Makkasau said the change in the capacity of the copper smelter was carried out as a result of the impact of the Covid-19 pandemic.  "The capacity of 900 thousand tons has been adjusted from the previous planned capacity of 1.3 million tons per year. This capacity adjustment was carried out due to development challenges due to the Covid-19 pandemic," he said in an official statement received by CNBC Indonesia, Wednesday (14/14/2020). 04/2021).  His party admitted that he would continue to increase efforts to prevent the spread of Covid-19 by restricting access to and from the smelter area under its operational area.  "Our business partners are also experiencing restrictions on official travel," he said.  However, he added, his party will continue to strive so that the targets set can be achieved, although with a lower capacity than the initial target that has been set.  The company targets the construction of this new smelter to be completed in 2023.  "With a lower capacity, the project completion schedule target can be achieved," he said optimistically.  Currently, his party is in the final evaluation stage of several consortiums of EPC contractors ( Engineering, Procurement, and Construction ) and is targeted to determine the winner of the auction in the near future.  "Amman targets to complete the process of determining the winner of the EPC tender in the near future. The licensing process related to construction, logistics and buildings will also continue to be carried out in parallel with the support of the local government," he said.  According to him, the change in the target capacity for the new smelter will also have an impact on the planned supply capacity for copper concentrate produced from the Batu Hijau mine and the potential for the Elang block managed by the company.  www.cnbcindonesia.com

- PT. Amman Mineral Nusa Tenggara (AMNT) will soon meet the NTB Provincial Government to discuss the continuation of the construction of the smelter which had stopped due to the Covid-19 pandemic.  The meeting is planned for late January or early February. The head of the NTB Bappeda, Amry Rakhman said, the last coordination with PT. AMNT was conducted last December. His party is still coordinating with the Ministry of Energy and Mineral Resources about their plans.  "What is the result of their coordination, to this day I have not coordinated again," he said.  Amry explained, PT. AMNT has planned to meet with the NTB Provincial Government and the Sumbawa Regency Government (KSB) regarding the continuation of the smelter construction. He said that until now, the construction of the smelter has not yet begun.  ''He gave me an answer, we need to meet in January or early February. To discuss matters related to industrial areas and smelters. So that we know what to do next,'' he said.  According to him, AMNT has carried out the land acquisition process for the smelter construction site. Likewise, the right to use the building has also been taken care of.   Based on information received by the NTB One Stop Licensing and Investment Service (DPMPTSP), after calling the mining company, at the end of 2020, the progress of the smelter construction currently only reached 24 percent.  PT. AMNT has obtained a permit for spatial planning for an area of ​​850 hectares. Where, 154 hectares of land acquisition process has been completed, 50 hectares of land cleaning, are ready for the location of the smelter construction implementation.  The impact of the Covid-19 pandemic changed the entire initial plan for the construction of the PT. AMNT at KSB. Since March 2020, due to Covid-19, AMNT has changed the entire original plan. Due to the COVID-19 pandemic, some plans have been delayed.  For example, the design engineering work was delayed which was supposed to be final in 2020. As a result, the design engineering work was delayed because the bid recruitment contractor was still on lockdown. Land preparation is also backward because it avoids direct contact. So that in the future the company will again plan to submit bids to contractors in February.  www.listrikindonesia.com   (Translated)

January 24, 2019 - PT Amman Mineral Industry, a subsidiary of copper and gold producer PT Amman Mineral Nusa Tenggara (AMNT), moves ahead with its plan to develop a smelter plant that will be located at Benete Bay in Sumbawa, West Nusa Tenggara province.  President Director of Amman Mineral Rachmat Makkasau said Thursday that the plan to develop the smelter remains on track.  As reported earlier, the company will build a smelter plant with a capacity of 1.3 million tons per annum.  For now, it pushes aside a plan to develop a joint smelter in collaboration with giant gold and copper mine Freeport Indonesia.  In November last year, Amman Mineral appointed Outotec the Front-End Engineering Design (FEED) of a new copper smelter to be located at Benete Bay in Sumbawa, Indonesia.  An FEED contract has been signed by both parties valued at approximately EUR 10 million.  Outotec’s scope of engineering covers the design of the entire copper smelter. The engineering will be based on Outotec® Flash Smelting and Flash Converting technology, and include an electrolytic refinery, slag concentrator, precious metals refinery, wet gas cleaning and Lurec® sulfuric acid plant as well as effluent treatment plant and its associated infrastructure.  Outotec’s design work will take place in the following nine months and is a continuation of the feasibility study conducted in 2017. Once completed, the new smelter is planned to primarily process Indonesian copper concentrate.  “PT Amman Mineral Industri set the overriding design criteria to be proven technology that fulfils the strict international environmental standards. We are happy to help them to meet their sustainability goals by designing a copper smelter based on the most advanced technology in the world”, says Kalle Härkki, Head of Outotec’s Metals, Energy & Water business.

November 8, 2018 - Outotec has confirmed it has secured a €10 million (US$11.4 million) front-end engineering design (FEED) contract for a copper smelter at the Benete Bay project in Sumbawa, Indonesia.  The nine-month agreement is with contract partner PT Amman Mineral Industri, part of copper and gold producer PT Amman Mineral Nusa Tenggara.The contract's scope includes design of the entire smelter with engineering based on Outotec's Flash Smelting and Flash Converting technology. It will include an electrolytic refinery and slag concentrator, as well as a precious metals refinery, wet gas cleaning and a Lurec sulphuric acid plant.An effluent treatment plant and associated infrastructure are also part of the FEED agreement.Once the smelter is in operation, it will mainly process Indonesian copper concentrate."PT Amman Mineral Industri set the overriding design criteria to be proven technology that fulfills the strict international environmental standards," Outotec metals, energy and water business head Kalle Härkki said.

- The government claims that copper miner PT Amman Mineral Nusa Tenggara -- previously named PT Newmont Nusa Tenggara -- will start construction of its smelter in early 2018 along the coastal areas of Sumbawa in West Nusa Tenggara.  “The construction is planned for early 2018. Currently, the company is still in the process of procuring [the materials],” said Bambang Susigit, the minerals business supervision director at the Energy and Mineral Resources Ministry, as reported by tempo.co on Tuesday.  The smelter, which is required for a Special Mining License (IUPK), is expected to be completed in the next five years. It is designed to purify 1 million tons of copper concentrate per year. Its capacity will be gradually increased to 2 million tons per year. The project costs an estimated US$2.2 billion.  Bambang’s statement was confirmed by Muhammad Lutfi, the main commissioner of PT Medco Energi Internasional.  “Our commitment is to construct smelters after the process of acquisition [of the company] is finished. By our calculations, construction will start in early 2018,” said Lutfi.  Medco holds a 50 percent share of Amman Mineral Investama, which controls 82.2 percent of Amman Mineral Nusa Tenggara.  Bambang called on Amman to immediately submit an environment impact analysis (amdal) document to the Environment and Forestry Ministry for the smelter project as required by law.  www.aseanaffairs.com
