PT Bintan Alumina Indonesia's Alumina Capacity Reaches 4 Million Tonnes per Year

On December 22,Nanshan Aluminium International Holdings Limited(stock code:2610.HK;hereinafter referred to as"Nanshan Aluminium International")announced that the alumina expansion project of its Indonesian subsidiary—PT Bintan Alumina Indonesia—has officially commenced operations.With this milestone,Nanshan Aluminium International's total designed annual alumina capacity has increased to 4 million tonnes,further consolidating its leadership in the Southeast Asian alumina sector.

This capacity expansion represents a key strategic initiative by Nanshan Aluminium International to further deepen its presence in the Southeast Asian market and respond to the growth in global aluminum demand.Building on the existing alumina capacity of 2 million tonnes per year already in operation,the new alumina project,with an additional designed capacity of 2 million tonnes per year,was efficiently implemented in two phases:The first phase,with an annual capacity of 1 million tonnes,commenced production in the third quarter of 2025,while the second phase,also with an annual capacity of 1 million tonnes,achieved full operation on December 20,2025,fully demonstrating the company's outstanding project execution capabilities.

To fully support the ramp-up of capacity,Nanshan Aluminium International has concurrently completed the construction and upgrading of key supporting infrastructure.A modern 70,000-tonne-class terminal has been completed and commissioned,equipped with high-efficiency loading,unloading,and conveying systems,significantly enhancing logistics throughput.At the same time,the coal-to-gas plant has been expanded,adding 700 million cubic meters of annual capacity to meet the requirements of scaled-up production.Within an integrated operating framework,end-to-end supporting systems,including power supply,water supply,gas supply,and logistics,have been fully interconnected and optimized.Leveraging Indonesia's abundant bauxite and coal resources,Nanshan Aluminium International has established a globally leading cost advantage in alumina production.

Hao Weisong,Chairman of the Board and Chief Executive Officer of Nanshan Aluminium International,stated that the company has completed a full suite of production and supporting facilities,including a captive power plant,a deep-water terminal,a self-built reservoir,and a coal-to-gas plant,enabling highly efficient,fully integrated operations from production to shipment.With the full ramp-up of the additional alumina capacity,Nanshan Aluminium International's comprehensive industrial chain advantages,from resource security and energy support to logistics hubs,have been clearly demonstrated.

At present,Nanshan Aluminium International has achieved a step-change increase in capacity while establishing strong competitive advantages in cost efficiency and market responsiveness.Its expanded capacity and cost advantages are expected to directly support the group's long-term profitability and business growth,further reinforcing its position as one of the leading alumina producers in Southeast Asia.

Looking ahead,Nanshan Aluminium International will leverage the competitive strengths of its Indonesia-based alumina operations,fully capitalize on local resources and locational advantages,and further advance the integrated development of the aluminum industry chain,thereby delivering sustainable long-term value to shareholders,customers,employees,and society.
