Resolution supporting the exploration development, processing and refining of critical minerals

The document title was updated from 'HR 2' to 'HR 2.1' to reflect the revision version.

Line numbers were added to the beginning of each paragraph to facilitate legislative tracking and markup.

A final page marker ('- END -') was inserted at the end of the text.

Added a specific list of minerals Montana produces, including copper, molybdenum, nickel, manganese, zinc, tungsten, antimony, chromium, and aluminum.

Added language explicitly linking the resolution to strengthening America's national defense supply chains.

Added a clause stating that critical minerals development in Montana follows global-leading labor, safety, public engagement, and environmental standards.

Changed the document status from a draft version (HR 2.1) to a final Enrolled Bill with added certification signatures for the Chief Clerk and Speaker of the House.

The document type changed from a committee bill (LC 2559) to a formal House Resolution (HR 2), altering the procedural stage of the legislation.

A full list of sponsoring legislators was added to the resolution header, which was previously blank in the committee version.

Page headers and footers were updated to reflect the new resolution number and include an 'Authorized Print Version' label.
