Entry into a Letter of Intent

On March 17, 2026, China Natural Resources, Inc. (the “Company”) entered into a non-binding Letter of Intent (“LOI”) with Feishang Group Limited, its principal shareholder (“Feishang”), to acquire 100% shares of a wholly owned subsidiary of Feishang that will own, directly or indirectly, 59.79% of the equity interest of HooRii Technology (HK) Limited (“HooRii”), a limited liability company incorporated in Hong Kong specializing in physical AI development, through the combination of IOT and artificial intelligence, to bring AI into the physical world (the “Acquisition”). The Company has established a special committee consisting of all of the independent directors to evaluate the Acquisition. Pursuant to the LOI, the Acquisition’s total consideration is estimated to range between US$37 million to US$40 million through a combination of cash and stock issuance. The Acquisition is subject to the negotiation and execution of definitive documentation, completion of due diligence, receipt of regulatory approvals, and necessary corporate approval, alongside other customary closing conditions.

Investors are cautioned that the LOI is non-binding and serves only as a preliminary expression of intent. The Company provides no assurance that a definitive agreement will be executed or that the proposed acquisition will be consummated on the terms described, or at all. Furthermore, the Company can offer no guarantee regarding the timing of the potential closing, which remains subject to the satisfaction of various closing conditions.

The foregoing description of the LOI is not complete and is qualified in its entirety by reference to the full text of the LOI, which is furnished as Exhibit 99.1 to this Current Report on Form 6-K. On March 19, 2026, the Company issued a press release announcing the LOI. A copy of the press release is attached as Exhibit 99.2.
