Severniy Katpar LLP controls one of the largest undeveloped tungsten resources globally, with April 2023 feasibility work reporting 1.4 million tonnes of tungsten trioxide (WO3).

The project aims to supply ammonium paratungstate from a Kazakhstan refinery into U.S. and global critical-minerals markets, and is part of a proposed business combination that would create Kaz Resources Inc., expected to trade on Nasdaq as KAZR.
