RE:Salt production? Until the feasibility study is completed (probably late November/early December) there won't be anything more than speculation on what's going to happen. A buyout is probably more likely than actually going to production, although that's certain not off the table.
Once the FS is done, if a buyout occurs actually construction and facilities will likely begin spring 2023 at the absolute earliest.
Triple Point Resources might actually see construction on facilities sooner than Atlas Salt, given the rapid timelines for hydrogen export to Germany that's being looked at.
