[SMM Manganese Ore Weekly Review] Manganese Ore Port Inventory Continues to Accumulate, Spot Prices Under Pressure

Published: Aug 07, 2026 17:18 (GMT+8)
Aug 7 News: At north China ports, manganese ore prices declined WoW across all grades: 46% Australian lumps (40-40.5 yuan/mtu), South African semi-carbonate (32.7-33.2 yuan/mtu), Gabonese ore (37.8-38.2 yuan/mtu), South African high-iron ore (28.5-29 yuan/mtu), and South African medium-iron ore (35-35.5 yuan/mtu). At south China ports, manganese ore prices were mixed WoW: 46% Australian lumps (42.9-43.4 yuan/mtu) remained flat, South African semi-carbonate (36.3-36.8 yuan/mtu) declined, Gabonese ore (40.6-41.1 yuan/mtu) declined, South African high-iron ore (31.2-31.7 yuan/mtu) declined, and South African medium-iron ore (38-38.5 yuan/mtu) remained flat. Manganese ore market prices are grinding lower, end-use demand is sluggish, and traders are commonly cutting prices to sell.

Aug 7 news:

North ports: 46% Australian lumps at 40-40.5 yuan/mtu, down WoW; South African semi-carbonate lumps at 32.7-33.2 yuan/mtu, down WoW; Gabonese lumps at 37.8-38.2 yuan/mtu, down WoW; South African high-iron lumps at 28.5-29 yuan/mtu, down WoW; South African medium-iron lumps at 35-35.5 yuan/mtu, down WoW.

South China ports: 46% Australian lumps at 42.9-43.4 yuan/mtu, flat WoW; South African semi-carbonate lumps at 36.3-36.8 yuan/mtu, down WoW; Gabonese lumps at 40.6-41.1 yuan/mtu, down WoW; South African high-iron lumps at 31.2-31.7 yuan/mtu, down WoW; South African medium-iron lumps at 38-38.5 yuan/mtu, flat WoW.

Manganese ore market prices continue to grind lower, end-use demand remains sluggish, and traders cutting prices to sell is relatively common.

Supply side, CML announced its September 2026 manganese ore offers to China, with Australian lumps (Mn>46%Fe<4%Si02<18%) quoted at $5.1/mtu, down $0.2/mtu MoM. South32’s offers to China for September 2026 shipment are South African semi-carbonate lumps at $4.5/mtu (down $0.25/mtu), Australian lumps at $5/mtu (down $0.1/mtu). Comilog’s September 2026 shipment offer of Gabonese lumps to China is $4.9/mtu (down $0.2/mtu). Manganese ore arrivals continue and inventories keep building up, prompting traders to sell spot manganese ore at lower prices.

Demand side, SiMn futures consolidate on a weak note, with deep market pessimism, failing to boost spot purchases. In the spot market, alloy producers are generally suffering losses. Operating rates in Inner Mongolia remain relatively stable, with some maintenance and load reduction, but capacity release from previously commissioned submerged arc furnaces also exists. Overall, mills have few inquiries for manganese ore, and purchasing sentiment is mediocre. In Ningxia, production cuts and output reductions are common among smelters, operating rates are low, and buying appetite for ore is weak. In south China, alloy plants have the lowest overall operating rates, mainly procuring on a rigid as-needed basis, with sluggish market trading activity. Currently, SiMn enterprises mostly adopt a procurement strategy of restocking based on rigid demand and small orders following the market, with weak trading activity in the traditional off-season. Transactions are dominated by small scattered orders, and actual manganese ore demand is weakening marginally.

Inventory side, Tianjin port saw inventory buildup, Qinzhou port saw slight destocking, and overall manganese ore inventory is at a relatively high level, suppressing the upward momentum of prices.

Currently, support from the cost side for the floor of ore prices has weakened. Downstream demand in the alloy sector is sluggish, with factories restocking only to meet rigid demand. Coupled with high port inventories and virtually no expectation of shortages, ore prices lack upward momentum. Port manganese ore prices are expected to continue grinding lower in the short term.

[SMM News] Brazil regulator orders partial halt at Sigma Lithium mine over ‘imminent risk’
On October 2(nd), Sigma Lithium has suspended all mining and industrial activities at its Grota do Cirilo operation in Brazil, its sole producing asset, pending a federal appeals court ruling on a preliminary injunction over its environmental licences. Brazil's national mining agency (ANM) had ordered mining halted on the eastern slope of the north pit. Concentrate output from the site is halted during the suspension, and sales of lithium fines continue. Sigma pushed back its 12-month production guidance of 240,000 mt by three months and maintains its FY2027 target of 330,000 mt of concentrate.

[SMM News] Lithium Argentina outlines phased expansion plan for Cauchari-Olaroz
Lithium Argentina confirmed a Stage 2 expansion at the Cauchari-Olaroz salt lake project in Argentina, adding 45,000 mt/y of lithium carbonate capacity and lifting total capacity to 85,000 mt/y. Of this, an initial 10,000 mt/y module using adsorption direct lithium extraction (DLE) is expected online in 2028. This estimates after-tax NPV at $3.1 billion and IRR at 28.5% at a lithium carbonate price of $18,000/mt, with operating costs of $5,006/mt. Total investment for Stage 2 is $1 billion. The project remains subject to regulatory approvals, and detailed engineering for the initial module is due later this year. The additional supply is scheduled from 2028 onward.

[SMM News] Patagonia Lithium completes 72-hour pump test at Cilon
Patagonia Lithium completed a 72-hour pump test at well eight on its Cilon concession, with a flow rate of 2,043 litres/hour and 146,800 litres extracted. Lithium concentration reached 232 ppm at 250m depth. About 34 kg of lithium was pumped, equal to 180 kg of lithium carbonate equivalent (LCE). In the 24-hour recovery test, the water level returned from 52.4m to the static level of 3.64m. The company identified an aquifer zone of interest between 226m and 324m depth and is updating its mineral resource estimate, with a scoping report to follow. The project is at the exploration stage, and no production timeline has been announced.
