                Exceeding Target, Construction of AMMAN Smelter
                             in December 2023 Reaches 76%

Jakarta, 5 February 2024 – PT Amman Mineral Industri, a subsidiary of PT Amman Mineral
Internasional Tbk ("Amman" or "Company” - stock code AMMN), continues its commitment to
completing a copper smelter and precious metal refinery (“PMR”), a national strategic project under
construction near the Company’s Batu Hijau copper-and-gold mine in West Sumbawa, Indonesia. An
independently verified quarterly progress report covering the period from October to December
2023 stated that construction progress of the copper smelter has reached 76.1%, which is 105.1% of
the scheduled target of 72.4%. Meanwhile, construction of the PMR has reached 72.7%, or 100.7% of
the year-end target of 72.1%.


Amman Vice President of Corporate Communications and Investor Relations Kartika Octaviana
stated that the Company is confident of reaching the completion target at the end of May 2024 for
both the smelter and PMR, with commissioning to begin in June 2024.


"This achievement demonstrates AMMAN's commitment as one of the largest copper-and-gold
mining companies in Indonesia to contribute to developing the national mining industry to benefit
the regional and national economy," explained Kartika.


Once in operation, the smelter and PMR will be able to process up to 900 thousand kilotons per year
(“ktpa”) of concentrate from the Batu Hijau mine, as well as the Elang project now in development.
Output from the smelter will reach 222 ktpa of copper cathode and 830 ktpa of sulfuric acid. The PMR
facility will produce 18 tpa of gold bullion, 55 tpa of silver bullion and 70 tpa of selenium.


In September 2023, AMMAN signed a Head of Agreement with Pertamina, Indonesia’s national
petroleum company, to supply liquefied natural gas to fuel a combined-cycle gas turbine currently
under construction. Powering the smelter and PMR with this low-emission fuel and highly efficient
power plant will minimize the environmental impact of new downstream facilities.
