Other North America REE resources on ASX

I see a few companies planning REE refining plants in North America but not sure where they plan to source feedstock locally. I like the idea of another North America play on the ASX given the government funding being offered up (as evidenced by ASM getting LOI's for $1.3B from EXIM (US) and EDC (Canada))

The following extract from the VML presentation shows just two ASX companies with resources; VML with Nechalacho and American Rare Earths (ARR) with Halleck Creek. Any others?

Halleck Creek looks big but both low grade (0.33% vs 1.4%) and low % of the high value NdPr combo (0.07% vs 0.34% - I think these should read 7% and 35%?). But they do seem to have a low cost leaching process to extract the REE's so likely lower CAPEX and OPEX? Anyone here into ARR?
