[SMM Flash] Premier African Minerals has identified an estimated US$19.1 million funding requirement through December 31, 2027, as it seeks additional capital for its Zulu Lithium and Tantalum Project in Zimbabwe and other corporate obligations. The company has called a general meeting for September 23, where shareholders will vote on resolutions providing additional share-issuance authority. Premier said its available funds are limited and warned that failure to secure further financing could materially affect the Zulu project and the wider group.​ The proposed authorities include the potential issuance of up to 58.63 billion new shares to provide funding flexibility, alongside separate provisions covering creditor settlements and conversion rights. The announcement highlights continued financing pressure surrounding Zulu as Premier works to optimise operations and progress the project towards sustainable production. For the tantalum market, securing sufficient capital will be important to Zulu’s ability to develop its prospective tantalum-bearing output, although the US$19.1 million represents an estimated funding requirement rather than financing already secured.

[SMM Flash] Rwanda is seeking greater Indian investment in its critical-minerals sector, highlighting tin, tungsten and tantalum (3Ts) among potential areas for cooperation. The opportunities were presented at an investment event hosted by the High Commission of Rwanda in India in Bengaluru. Rwanda is seeking to expand domestic mineral processing and capture greater value from its resources, while India is strengthening overseas critical-mineral supply chains through initiatives including its National Critical Minerals Mission. The initiative follows the first India-Rwanda Joint Trade Committee meeting held in New Delhi on July 30–31, where critical minerals were identified as a priority area for bilateral cooperation. Potential collaboration could include geological exploration, processing, investment and supply-chain development. However, no specific tantalum mine investment, financing package or offtake agreement was announced, meaning the development currently represents investment promotion rather than committed new supply. Greater Indian participation could eventually diversify investment and downstream channels within Rwanda's 3T industry.

[SMM Flash] Researchers have reported new experimental measurements of tantalum under extreme pressure and temperature conditions in a study accepted by the American Physical Society's Physical Review B on September 1. The researchers combined temperature measurements with simultaneous X-ray diffraction after shock compression and release. The body-centred cubic tantalum phase was observed at 142 GPa, while the experiments constrained melting behaviour at pressures up to 142 GPa and temperatures reaching approximately 5,880 K. The research does not indicate an immediate change in tantalum supply, demand or prices, but improves understanding of the metal's behaviour under extreme operating conditions. Tantalum's high melting point, corrosion resistance and thermal stability support its use in demanding technological applications, and more accurate phase-boundary data can improve material modelling under extreme environments. The study provides a framework for further temperature measurements of materials subjected to laser-driven dynamic compression.
