Item 1.01. Entry into a Material Definitive Agreement.

On June 12, 2026, effective as of June 9, 2026, American Clean Resources Group, Inc. (the "Company") entered into a Joint Exploration and Development Agreement (the "Agreement") with TRG Holdings, LLC, a Nevada limited liability company ("TRG Holdings"). The Agreement establishes a framework for the joint exploration, technical evaluation, regulatory pursuit, and commercial scoping of an integrated energy generation, critical minerals processing, and data center infrastructure campus on or adjacent to the Company's Millers Hub property in Esmeralda County, Nevada (the "Project").

The Agreement is the project-specific framework for the Millers Hub property contemplated by a previously executed, non-binding joint venture framework dated May 6, 2026 among the Company, the TRG Holdings parties (including its affiliates H2O, LLC and ARMtech), and American Clean Energy LLC ("ACE"), which established a non-binding platform anticipating that individual project sites would be advanced under separate project-specific agreements. As previously disclosed in the Company's Current Report on Form 8-K filed on May 28, 2026, ACE is a joint venture between the Company's wholly owned subsidiary, ACRG Energy Holdings, Inc., and Phoenix New Era, LLC, in which ACRG Energy Holdings holds a controlling membership interest. The parties anticipate that ACE will participate in any definitive agreement for the Project in a role related to energy offtake structuring and data center integration, drawing on the experience of ACE's principals in developing and financing large-scale data center and power infrastructure projects.

Under the Agreement, the parties will jointly pursue, among other activities, a geothermal resource assessment, the pursuit of a Solar Energy Zone designation and associated federal land use authorizations, the pursuit of geothermal leasing rights from the Bureau of Land Management, and technical and commercial scoping of the integrated campus. The Agreement has an initial term of eighteen (18) months, subject to extension by mutual agreement.

The Agreement is binding with respect to certain obligations, including mutual exclusivity within a defined geographic area surrounding the Millers Hub property, the sharing of approved third-party joint work costs, confidentiality, and coordination of regulatory and public disclosures. The Agreement does not itself establish an operating joint venture, partnership, or definitive commercial relationship for the development, construction, ownership, or operation of the Project, does not transfer any interest in the Company's real property or mineral rights, and does not commit either party to fund project capital expenditures beyond an agreed joint work budget. Any operating relationship would be effected only through a definitive agreement to be negotiated following completion of the joint work, and the specific economic and governance terms of any such definitive agreement remain subject to good-faith negotiation.

The foregoing description of the Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Agreement, a copy of which the Company intends to file as an exhibit to its next periodic report.
