NEW YORK & ASTANA, Kazakhstan -- (Business Wire)

Skyline Builders Group Holding Limited (“Skyline” or “SKBL”) (Nasdaq: SKBL) and Cove Kaz Capital Group LLC (“Cove Kaz”), a privately-held geological exploration and mining company with operations in Kazakhstan, today announced the companies entered into a Transaction Agreement (the “Transaction Agreement”) to effect a business combination. Upon completion of the business combination, the combined company plans to operate under the name “Kaz Resources Inc.” and trade on Nasdaq under the ticker symbol “KAZR."

“Cove Kaz is positioned to become a global leader in the mining, extraction, and processing of strategic minerals and metals aimed towards the United States defense and industrial base, specifically tungsten. Our company has existing and pending mining business under development in Kazakhstan that together form a unique portfolio of advanced-exploration and late-stage critical minerals projects. This transaction demonstrates the continued financial growth of our business and will support our financial plan to develop and construct mining and processing projects throughout Kazakhstan,” said Pini Althaus, Executive Chairman of Cove Kaz.

“With this transaction, Skyline will be fulfilling its 2025 announced strategic direction to become a material supplier of critical minerals to the United States. Cove Kaz has established a platform to develop high-value minerals and metals in Kazakhstan, from upstream to downstream production, through joint venture agreements with Kazakhstan’s national mining company and numerous geological land concessions awarded by the Kazakhstan government. The combined company is poised to develop multi-generational projects to supply the United States with tungsten, lithium, rare earths, beryllium, tantalum, niobium, rubidium, and other critical minerals,” said Paul E. Mann, Executive Chairman of Skyline and ASP Isotopes (Nasdaq: ASPI).

The business combination, which will also include the acquisition of Kaz Critical Minerals LLP, the holder of 15 licenses in Kazakhstan, has received approval by the boards of directors of both companies and is expected to close in the fourth quarter of 2026 or early 2027, subject to certain closing conditions, including the approval by Skyline shareholders, receipt of regulatory approvals and the effectiveness of a registration statement to be filed with the U.S. Securities and Exchange Commission. The investment was led by American Ventures, LLC.

Acquisition of Largest Known Undeveloped Tungsten Resource Globally

Underlying the business combination is Cove Kaz’s acquisition from Kazakhstan’s National Mining Company, Tau-Ken Samruk, of a 70% ownership interest in Severniy Katpar LLP., which holds licenses to two key projects in Kazakhstan – Northern Katpar and Upper Kairakty (the “Projects”) – located less than 20 miles apart by road in the established Karaganda mining district in Central Kazakhstan, less than 100 miles south of the City of Karaganda. Tau-Ken Samruk will retain 30% ownership in Severniy Katpar LLP.

Severniy Katpar LLP currently owns the largest known undeveloped tungsten resource globally. The most recent feasibility studies completed in April 2023 reported total JORC-compliant mineral resources containing 1.4 million tonnes of tungsten trioxide (WO3), representing approximately 70% of Kazakhstan’s estimated 2 million tonnes of tungsten resources. For perspective, the U.S. Geological Survey estimates China’s reserves at 2.4 million tonnes.

The current feasibility studies support production of approximately 5,000 metric tonnes per annum (mtpa) at Northern Katpar, and 7,000 mtpa from Upper Kairakty, for a total of 12,000 mtpa, representing approximately 15% of current global production.

The original joint venture announcement was made during the C5+1 Leaders’ Summit in Washington, D.C. by President Donald J. Trump and President Kassym-Jomart Tokayev. The project has benefited from strong trade advocacy and interagency coordination. Since 2023, the U.S. Departments of Commerce and State have provided commercial diplomacy in support of the company’s critical minerals business efforts in Kazakhstan.

For the Projects, the Export-Import Bank of the United States (EXIM) has issued a Letter of Interest for up to $900 million in project financing, and the U.S. International Development Finance Corporation (DFC) has issued a Letter of Interest for up to $700 million. Cove Kaz will be responsible for marketing 100% of project output and has entered into a Letter of Intent with the International Trade Administration at the U.S. Department of Commerce to prioritize U.S. Government and American commercial needs. Total development costs are estimated at approximately $1.1 billion.

Cove Kaz announced the financial closing and successful acquisition of its 70% ownership interest in Severniy Katpar LLP on April 29, 2026. The joint venture with Tau-Ken Samruk National Mining Company will now advance towards the commencement of a Definitive Feasibility Study in the second half of 2026.

Other Projects in Kazakhstan

In 2023, Kaz Resources (through its wholly owned subsidiary Kaz Critical Minerals LLP), became the first U.S. company to receive critical minerals and rare earths land concessions in Kazakhstan. Kaz Critical Minerals LLP is the holder of fifteen critical minerals concessions and a license for lithium tailings concessions in Kazakhstan. These concessions include minerals such as rare earth elements, lithium, tantalum, beryllium, niobium, cesium and tin.

In March 2025, Cove Kaz Capital Group LLC and JSC Qazgeology (a subsidiary of Kazakhstan's national mining company Tau-Ken Samruk) officially completed a joint venture focused on exploring and developing the Akbulak Rare Earth Project in Kazakhstan's Kostanay Region, which holds a historical resource of 380,000 tons of rare earth oxides , including neodymium, praseodymium, and yttrium, critical for permanent magnets, electronics, and medicine. Cove Kaz Capital Group holds 75% and Qazgeology 25%, with Cove Kaz Capital financing exploration until reserves are formally listed.
