Skyline Builders Group Holding Ltd. (NASDAQ: SKBL) delivered a classic micro-cap merger rollercoaster Thursday, jumping more than 12% in regular trading before giving back nearly 19% in after-hours action following news of a complex business combination that will transform the small construction-services firm into a major player in the global critical minerals space.
The Hong Kong-based company announced it has signed a definitive Transaction Agreement with Cove Kaz Capital Group LLC, Kaz Resources LLC, and a newly formed merger subsidiary to create Kaz Resources Inc., which is expected to list on Nasdaq under the ticker KAZR.
Under the deal, Cove Kaz — which holds a controlling 70% interest in one of the world’s largest undeveloped tungsten resources — will effectively become the core operating business. The flagship asset is the Northern Katpar and Upper Kairakty projects in Kazakhstan’s Karaganda region, a joint venture with state-owned Tau-Ken Samruk. Together they represent an estimated 1.4 million tonnes of WO₃ (tungsten trioxide) under JORC standards — the largest known undeveloped tungsten deposit globally — with potential annual production of approximately 12,000 metric tonnes, equal to roughly 15% of current worldwide output.

In addition to tungsten and molybdenum, the combined entity will control 15 additional critical minerals licenses through Kaz Critical Minerals LLP, covering rare earth elements, lithium, tantalum, beryllium, niobium and more. The portfolio also includes a 75% stake in the Akbulak rare earth project.
The transaction includes several restructuring steps: a new holding entity will be formed in Kazakhstan’s Astana International Financial Centre, Cove Kaz will convert into a Delaware corporation renamed “Kaz Resources Inc.,” and Skyline Builders will divest its legacy civil engineering and construction operations in Hong Kong and China to focus exclusively on the minerals business.
Skyline shareholders will receive a 1:1 conversion of their common shares into the new public company. The agreement also features a $23.1 million bridge loan from Skyline to Cove Kaz at 10% interest and requires the combined company to maintain minimum net cash reserves.
U.S. government financing support appears strong. The companies have received non-binding Letters of Interest from the U.S. Export-Import Bank (up to $900 million) and the U.S. Development Finance Corporation (up to $700 million) to help fund project development.

The deal is expected to close in the fourth quarter of 2026 or early 2027, subject to shareholder approval, regulatory clearances, and standard closing conditions.
Market Reaction
SKBL shares closed regular trading at $4.55, up 12.62% on volume exceeding 3.2 million shares. In after-hours trading the stock quickly slid more than 18%, reflecting typical profit-taking and uncertainty around the long timeline and execution risks inherent in large-scale mining projects.
At current levels the market capitalization remains modest at roughly $65 million — a small valuation for assets that proponents claim could position the new company as a strategically vital, non-China source of tungsten and other critical minerals essential to U.S. supply-chain security.
Analysts note that the deal carries both significant upside potential — driven by geopolitical tailwinds and U.S. financing interest — and substantial risks, including development costs estimated near $1.1 billion, regulatory hurdles in Kazakhstan, and the multi-year timeline before meaningful production begins.
