Not only is it opening up but several other large scale projects are already being considered in the USA, including one in Atolia, California that I have been privileged enough to personally visit.
Watch the markets for the metals most used in wartime. That tells you pretty quickly when conflict is near.
This isn't so much "conflict is near" as much as reaction to a defense-related policy. The entire US defense supply chain will be banned from >80% of tungsten supply at the end of the year, while also being demanded to up production to make up for depleted stockpiles from Iran and Ukraine.
I wonder if there’s path dependence there. It _seems_ like just because you build up lots of “defence” tech that doesn’t necessarily mean you _have_ to use it? Or does it? I wonder what happened with those markets during the Cold War.
