[SMM Express] NioBay Metals Inc. has successfully produced high-purity niobium and tantalum oxides from its Crevier Project in Québec, achieving approximately 99.6% niobium oxide (Nb₂O₅) and 99.98% tantalum oxide (Ta₂O₅). The purification programme, completed with processing and analytical work conducted by SGS Canada Inc., confirms the effectiveness of the company's metallurgical and hydrometallurgical flowsheet, including a calcination stage at temperatures of up to 1,050°C.

According to NioBay, the oxide products meet the specifications of certain potential customers, representing a significant technical milestone for the Crevier Project. The company is evaluating the project's potential to produce niobium oxide for battery and superalloy applications, following earlier studies indicating favourable technical and economic parameters.

The production of high-purity niobium and tantalum oxides signifies continued progress in downstream processing capabilities outside traditional supply regions. While the demand for high-specification materials grows across battery, aerospace and advanced manufacturing sectors, successful purification milestones could strengthen future supply and support value addition within the niobium and tantalum supply chain.

Germanium Prices Stable Post-Holiday, Ingot and Dioxide Remain Unchanged at 27,250 and 19,250 Yuan/kg

The supply-demand balance remains unchanged, and germanium prices continue to fluctuate on a firm footing. Germanium ingot (50Ω/cm) is quoted at 27,250 yuan/kg, and germanium dioxide (99.999%) at 19,250 yuan/kg; both prices are flat compared with the pre-holiday level, with no price adjustments in the two trading days after the holiday. Previously on September 24, germanium ingot and germanium dioxide were raised by 250 yuan/kg and 100 yuan/kg respectively. The market has entered a phase of high-level digestion after the holiday.

Rwanda spot offers at “4.8+” leave one buyer waiting

[SMM Tantalum Flash] A trading contact said on 9 October that it was still receiving Rwandan tantalum offers at “4.8+” and had bought no tantalum in the preceding few weeks. Other contacts in the supplied sample described offers above US$4 per kg per grade percentage point. The “4.8+” message did not restate its pricing unit, assay, delivery basis or the dates of the underlying offers. It is a received asking indication, not a transaction price. The contact said its Rwanda tin flows remained stable, but it had held off buying tantalum while considering air-freight economics and had shifted more attention to West Africa. It reported a Nigerian offer and expressed interest in a Sierra Leone trader; neither was described as a completed tantalum purchase. These conversations show how one buyer is responding to the offers, without establishing a representative Rwanda price or a wider change in trade flows.
