PT Inalum, Indonesia's state-owned aluminum giant, called on the government to suspend the construction of new alumina and aluminum plants on Tuesday, citing concerns about oversupply and pressure on the country's bauxite reserves. Melati Sarnita, CEO of Inalum, pointed out that Inalum is concerned that the aluminum industry will face similar problems to the nickel industry after rapid growth, such as oversupply affecting global prices and environmental issues. Inalum cited market data to estimate that once all the alumina projects under construction start operating, Indonesia's alumina capacity will increase from the current about 9 million tons to 29.8 million tons. Melati said that once all projects are completed, the original aluminum capacity is expected to increase from the current

SMM News, March 31 According to SMM data, the average tax-inclusive full cost of domestic aluminum industry in March 2026 rose 0.5% MoM and fell 5.7% YoY, mainly due to a slight rebound in alumina raw material costs during the period. In March, Middle East production cuts pushed up aluminum prices in and outside China. The SMM A00 monthly average spot price (February 26-March 25) rose 2.9% MoM, and aluminum profit margins expanded to 8,316 yuan/mt. Based on monthly average price calculations, 100% of China’s operating aluminum capacity was profitable in March. From the cost breakdown side: Alumina raw materials : According to SMM data, the monthly average of the SMM alumina index in March was 2,685 yuan/mt (January 26-February 25), up 2.4% MoM. During the month, total operating alumina capacity was basically stable, but the Middle East geopolitical conflict raised ocean freight rates for alumina and bauxite, and domestic alumina costs are expected to move higher. Futures prices drove spot prices higher, lifting the monthly average alumina price. Entering April, the upward momentum in spot alumina prices at month-end March appeared slightly insufficient. Some new projects are expected to come online in April or ramp up operating capacity, but as the base price at the beginning of the month was already at a high level, alumina raw material costs in April are expected to post a slight increase. Auxiliary materials market : In March, both prebaked anode and fluoride salt prices pulled back, lowering aluminum auxiliary material costs. Entering April, the Middle East geopolitical conflict raised international oil prices, and higher costs continued to push up petroleum coke prices, which in turn supported higher prebaked anode prices. The April prebaked anode tender price at a large aluminum plant in Shandong rose 300 yuan/mt MoM; for aluminum fluoride, prices are also expected to rise significantly in April due to higher raw material costs. Overall, auxiliary material costs are expected to increase significantly in April. Electricity prices : Electricity prices were generally stable in March. Entering April, power prices are expected to remain broadly stable, and aluminum power costs are expected to hold steady. Overall, in March 2026, SMM expected the weighted average tax-inclusive full cost of dometstic aluminum industry to rise slightly; in April, it was expected to increase significantly MoM, with the average at around 16,150-16,550 yuan/mt.

The US Treasury (OFAC) has issued new licenses lifting major sanctions on Venezuela’s gold and mining industries, including state-owned miner Minerven. Following the 2026 political shift in Caracas, this move allows companies to resume investments, provide technical services, and sign contracts. The policy aims to secure global access to Venezuela's vast reserves of gold, bauxite, and rare minerals essential for high-tech supply chains.

【SMM Steel】A cyclone that earlier hit Australia's northeast is now threatening LNG and mining ops in the west. System Narelle is expected to intensify as it moves parallel to the Pilbara coast. It threatens key LNG facilities and iron ore mines. Ports are clearing vessels. Australia, the top iron ore exporter, remains vulnerable. Narelle earlier forced closures of bauxite and manganese mines.

According to foreign media reports, the Odisha state government recently announced that it will auction 34 mineral sites in the 2026-27 fiscal year, including 25 major mineral sitesand 9 key strategic mineral sites, distributed across 12 districts—Keonjhar, Sundargarh, Mayurbhanj, Balangir, Rayagaada, Nuapada, Deogarh, Kalahandi, Subarnapur, Nayagarh, Malkangiri, and Koraput. The 25 major mining sites include 5 iron ore sites, 6 bauxite sites, 4 mixed iron-manganese sites, 3 quartz sites, 2 limestone sites, 1 manganese sites, 1 copper sites, and several mixed sites.
