Rio Tinto's (ASX:RIO) and BHP's (ASX:BHP) Arizona-based joint venture, the Resolution Copper project, was selected for fast-tracked federal permitting, under US President Donald Trump administration's executive order aimed at boosting domestic mineral production and reducing reliance on foreign sources, according to a Tuesday statement by the Federal Permitting Improvement Steering Council.

The council has marked Resolution Copper as a "transparency project" to provide greater transparency and efficiency in the permitting process, the statement said.

The project's inclusion in the federal permitting dashboard will allow stakeholders to track its progress in real-time, alongside the expedited permitting process, the statement added.
