Good question, In this announcement it pretty much sums it up

Following successful negotiations with the Traditional Owners, with the assistance of the Northern
Land Council, under the Aboriginal Land Rights (Northern Territory) Act 1976, Eclipse Metals
Limited (“Eclipse Metals” or the “Company’) has formalised the terms of a life time agreement
on EL27584 covering the Devil’s Elbow uranium, gold, palladium prospect.Then check out: eclipseuranium.com.au/wp-content/uploads/2016/08/Rio-Tinto-Eclipse-Metals-Ltd-Farm-In-Joint-Venture.pdf
Paints a picture of what Rio's intrest is with Devil's Elbow and the wider Liverpool project
Essentially Rio couldn't get permission from the land council, EPM has that permission in the Liverpool Project

The world's largest U miners (Rio, Cameco) operate there. Now I can't speak for the aboriginal communities and the land council living there though I have a sneaking suspicion they didn't quite get along with massive multinational corporations who's board weren't really wanting to consult and speak to the locals regarding their land and the mining project there. YET Carl was granted permission to mine in that tenement. As I'm sure the lands council and locals found him much more approachable and accommodating. not a big issue but a BIG POSITIVE. Rock Hill just adds more resources to the NT portfolio
hope that leads you to a path of enlightenment and good research.
