Following the announcement of the joint venture between US-based Cove Capital LLC and Kazakhstan’s National Mining Company, JSC Tau-Ken Samruk, further details have emerged regarding the development timeline and scale of the Northern Katpar and Upper Kairakty tungsten projects.
Cove Kaz Capital Group LLC (“Cove Kaz”), a portfolio company of U.S.-based Cove Capital LLC, will hold a 70 per cent interest, with Tau-Ken Samruk retaining 30 per cent ownership of Severniy Katpar LLP, which owns the Northern Katpar and Upper Kairakty tungsten projects.
Cove Kaz will oversee marketing of 100 per cent of project output and has entered into a Letter of Intent with the International Trade Administration at the U.S. Department of Commerce to prioritise supply for U.S. government and commercial needs.
The announcement was made in Washington, D.C., during the C5+1 Leaders’ Summit by U.S. President Donald J. Trump and Kazakhstan President Kassym-Jomart Tokayev.
Total development costs for the Northern Katpar and Upper Kairakty projects are estimated at USD $1.1 billion. The Export-Import Bank of the United States has issued a Letter of Interest for USD $900 million in financing, complemented by a similar commitment from the U.S. International Development Finance Corporation.
Cove Kaz’s project team will be led by Dominic Heaton, who previously oversaw development of the Nui Phao integrated tungsten mine and refinery in Vietnam – the world’s largest tungsten operation outside China. Preparatory work has already commenced to support a Definitive Feasibility Study for Northern Katpar, including the establishment of downstream refining capacity in Kazakhstan to produce ammonium paratungstate (APT) and other tungsten compounds.
Pini Althaus, Chief Executive Officer of Cove Capital and Cove Kaz Capital, expressed gratitude for U.S. and Kazakh government support:
“On behalf of Cove Capital and Cove Kaz, I wish to thank President Donald J. Trump, Secretary of Commerce Howard Lutnick, and the U.S. Trade Advocacy Center for their exceptional engagement. Their efforts have aligned financing, offtake pathways, and policy support to deliver a secure, allied tungsten supply for America’s industrial and defence needs.
“I also wish to thank President Kassym-Jomart Tokayev for his leadership and partnership. This collaboration is a win for both nations—strengthening U.S. supply chains while fostering investment and long-term prosperity in Kazakhstan.”
Tungsten – A Critical Industrial and Defence Mineral
Tungsten is ranked by the U.S. Defense Logistics Agency as a “material of interest” and by the European Union as the raw material of highest economic importance due to its unique physical properties: the highest tensile strength at high temperatures, the highest melting point of any metal, and exceptional corrosion resistance.
Its density and durability make tungsten indispensable in high-performance cutting and drilling tools, aerospace alloys, semiconductor contacts, and radiation shielding. In defence applications, tungsten is used in armour-piercing munitions, missile components, aircraft ballast, and other high-stress environments.
Currently, China controls over 80 per cent of global tungsten production and processing. In February 2025, China imposed new export restrictions on tungsten and tungsten-containing products to the United States.
Severniy Katpar LLP
Severniy Katpar LLP holds licences for two projects—Northern Katpar and Upper Kairakty—located approximately 30 kilometres apart in the established Karaganda mining district of central Kazakhstan, less than 160 kilometres south of the city of Karaganda.
Feasibility studies completed in April 2023 report total JORC-compliant mineral resources of 1.4 million tonnes of tungsten trioxide (WO₃), accounting for around 70 per cent of Kazakhstan’s total tungsten resources. For comparison, the U.S. Geological Survey estimates China’s reserves at 2.4 million tonnes.
Combined production from both projects is expected to reach 12,000 metric tonnes per annum (mtpa) of tungsten trioxide—approximately 15 per cent of current global output.
Cove Capital’s Broader Commitment in Kazakhstan
Cove Capital’s portfolio company, Kaz Resources LLC, became in 2023 the first U.S. entity to receive critical minerals and rare earth concessions in Kazakhstan. These include licences for 13 minerals such as lithium, tantalum, beryllium, niobium, and rare earth elements.
In 2024, Cove Capital and Tau-Ken Samruk formalised a joint venture for exploration of rare earths at the Akbulak project in the Kostanay region, with Cove holding 75 per cent and “Qazgeology” JSC 25 per cent. Cove is fully financing exploration activities until reserves are booked.
