Vale (NYSE: VALE) has announced a strategic goal to expand its copper and nickel reserves and resources in Canada and Brazil by 20% between 2024 and 2027. Following a strong 2025 performance, Vale reported that its total nickel reserves and resources rose 13% to 14 million tonnes, while copper increased 6% to 53 million tonnes.

Cornish Tin Limited has closed its latest funding round at over £2.2 million, surpassing its initial target with a pre-money valuation of £29 million. Proceeds will fast-track exploration at the high-grade Great Wheal Vor and Tregonning South projects in Cornwall. With global tin prices recently hitting highs above $50,000/t and rising lithium demand for EVs, the company aims to secure a critical domestic supply chain for the UK and European technology and renewable energy sectors.

On March 25, the Guoneng Yuci Energy Storage Primary Frequency Regulation Construction Project, undertaken by the Energy Construction Branch, successfully completed all procedures for grid connection and commissioning, was successfully connected to the power grid system, and was officially put into operation. This milestone event marked the company’s breakthrough from zero in the niche field of flywheel energy storage, a new-type energy storage segment. As Huadian Engineering’s first flywheel energy storage demonstration project, it carried the dual mission of technological exploration and market expansion. The core construction content of the project was an 8 MW/800 kWh magnetic levitation flywheel energy storage unit.

Deepvein Mining has unveiled DeepSight Exploration, an integrated hardware-software system utilizing drone swarms and quadruped robots for end-to-end mineral exploration. Validated at a copper project in Namibia, the platform combines autonomous mapping, sampling, and geological intelligence to pinpoint high-potential targets. This robotics-first approach aims to reduce exploration cycles by 30 to 50 percent and lower costs by approximately 40 percent while significantly improving field safety in complex environments.

K2 Gold has successfully completed its 2026 reverse circulation (RC) drilling program at the Si2 Gold Project in Nevada, USA. The campaign comprised eight drill holes totaling 3,871 meters across five target areas, including inaugural exploration at three new zones. Drilling encountered extensive epithermal alteration and quartz veining, validating a geological model targeting the deeper "boiling zone" where higher-grade gold and silver deposits may exist. Assay results from the sampled materials are currently pending laboratory analysis.

Recently, the team led by Meng Qingbo at the Institute of Physics, Chinese Academy of Sciences, once again set a new record in new-type thin-film PV copper-zinc-tin-sulfur-selenium (CZTSSe) technology, raising the battery’s certified efficiency to 16.6%, marking the technology’s official crossing of the critical threshold for industrialisation from 15 to 16. Composed of common, low-cost elements such as copper, zinc, and tin, CZTSSe materials not only avoid reliance on rare metals but also offer strong resistance to space radiation. At present, the team has also completed the development of high performance flexible batteries and modules, and this technology is expected to achieve large-scale application in fields such as low-Earth-orbit satellite internet, space-based energy bases, and aerospace equipment in the future. This progress not only established China’s internationally leading position in this field, but also opened up strategic, high-value-added application prospects for tin metal in new energy and deep-space exploration.

The Ministry of Agriculture and Environment in Vietnam has issued Consolidated Document No. 21/VBHN-BNNMT, detailing a number of provisions, including regulations on the management of rare earth elements. Specifically, in addition to complying with regulations on strategic and important minerals, the surveying, exploration, exploitation, processing, and use of rare earths must follow the national rare earth usage strategy. Activities related must ensure the principles of resource protection, environmental protection, and sustainable development; link extraction and processing with deep processing to increase added value and ensure technological self-reliance; not export rare earth minerals that have not met the required deep-processing standards; and only export deeply processed products.

[SMM Rare Earth Flash] Australian exploration and development company VHM announced on March 23 that it had approved the transition of its Goschen rare earth and mineral sands project in Victoria to full-scale development, abandoning its previous phased advancement strategy and directly launching large-scale operations with annual processing capacity of 5 million mt. The project was granted major project status by the Australian federal government in 2021 and had completed pre-feasibility and definitive feasibility studies, with development conditions fully in place. This move will accelerate the release of the project's resource potential and support the development of Australia's rare earth supply chain.
