Spartan Metals announced the confirmation of two tungsten skarn zones at the Tungstonia claims within its wholly owned Eagle Project in Nevada, US. As part of its ongoing exploration programme launched in May 2026, rock sampling from the historic Yellow Jacket Mine within the project returned tungsten trioxide grades ranging from 0.89% to 1.87%. Crucially, assays from the mine entrance and dumps detected notable concentrations of zinc (up to 3.3%) and 1,320 ppm beryllium, the latter being a newly discovered critical metal at the property. Backpack core drilling at the mine also intercepted a 0.3-meter interval grading 0.21% tungsten trioxide and 0.33% zinc. The confirmed mineralization, spanning an estimated 2-kilometer area, hosts a complex system of tungsten, molybdenum, beryllium, rubidium, and silver. Spartan Metals intends to launch approximately 3,000 meters of diamond core drilling at selected targets from early to mid-August to further untangle this expanding mineralized system.

Xinjinlu Group announced in June a planned investment of RMB 496 million to implement integrated mining, dressing, and metallurgical upgrades at its Guangxi Limu Mining subsidiary. The project includes upgrading mining operations to 600,000 tons/year, constructing a 1.5 million tons/year dressing line, building a tantalum-niobium hydrometallurgical workshop, and recovering associated metals like rubidium from tailings. Upon completion, it will form a complete industrial chain for tantalum, niobium, tin, and tungsten, yielding approximately 840 tons of tantalum oxide and 867 tons of niobium oxide annually.

On May 19, Sinomine Resource Group Co., Ltd. issued an announcement stating that it plans to issue A-shares to specific qualified investors, raising a total amount of approximately 5.2 billion yuan through the private placement. The maximum number of shares to be issued is 216,447,563, not exceeding 30% of the company's total share capital before the issuance. The fund-raising investment projects for this private placement focus on Sinomine Resource's main business, including the annual 100,000-ton lithium sulfate project in Zimbabwe, the Kitumba copper mine project in Zambia, and the annual 2,000-ton cesium-rubidium product project of Jiangxi Sinomine Advanced Materials Co., Ltd.

Ionic Mineral Technologies (IMT) from Utah announced the discovery of a massive rare earth and other critical metals deposit, which it may be "one of the largest deposits in North America" to date. Last week, IMT revealed that analysis of samples from the Silicon Ridge project in Utah indicates this is a halloysite-controlled ion-adsorption type deposit. Resources in such deposits are easier to extract compared to conventional "hard-rock" lithium ore. The company also stated that over 70% of the world's heavy rare earth resources come from ion-adsorption type rare earth deposits. Furthermore, this deposit is not only rich in rare earth resources but also contains various critical metals such as gallium, germanium, rubidium, cesium, scandium, lithium, vanadium, tungsten, and niobium.

Recently, US magnet manufacturer eVAC shipped the first batch of NdFeB permanent magnets from its Sumter plant in South Carolina, marking a critical step in the localization of rare earth permanent magnet production in the US. This delivery is considered the first commercial production of rare earth magnets in the country. At the same time, positive news emerged from domestic resource exploration in the US—Ion Mineral Technology discovered an ion-adsorption rare earth ore deposit at its Silicon Ridge project in Utah. This deposit is not only rich in rare earths but also contains 16 critical metals, including gallium, germanium, and rubidium. This discovery could become one of the largest critical mineral deposits in North America.

A mining company from Utah claims to have discovered a massive deposit of rare earths and other critical metals, describing it as potentially "one of the largest deposits in North America discovered to date." Ionic Mineral Technologies (IMT) announced last week that sample analysis from its Silicon Ridge project in Utah confirmed it as a halloysite-controlled ion-adsorption deposit, which is easier to extract compared to traditional "hard-rock" lithium ore. The company stated that ion-adsorption rare earth deposits account for over 70% of the world's heavy rare earth resources. Additionally, the deposit is not only rich in rare earths but also contains gallium, germanium, rubidium, cesium, scandium, lithium, vanadium, tungsten, and niobium.
