A US investment firm partly owned by the sons of President Donald Trump acquired a stake in a major tungsten mining project in Kazakhstan.

Dominari Securities, in which Eric Trump and Donald Trump Jr. hold ownership interests, purchased a 20% stake in Kaz Resources, a US-based company developing tungsten deposits in Kazakhstan, The Caspian Post reports via DW.

Kaz Resources signed an agreement with Kazakhstan's state mining company Tau-Ken Samruk in November 2025 to jointly develop tungsten deposits in the country. Investors from Dominari Securities acquired their stake in the project while negotiations were underway.

Cantor Fitzgerald, overseen by Brandon Lutnick and Kyle Lutnick-the sons of US Commerce Secretary Howard Lutnick-helped one of the project's investors raise $210 million to finance the venture. The firm could have earned millions of dollars in fees for its role.

Trump's sons and their partners invested in the project just six days before US and Kazakh officials signed an agreement in Washington on November 6, 2025, to cooperate on the development of mineral deposits.

Earlier, in April 2025, Tau-Ken Samruk announced the sale of a 70% stake in the North Katpar tungsten deposit in Kazakhstan's Karaganda Region to Cove Kaz Capital Group, a portfolio company of Kaz Resources.
