I added a single reference point for the proposed Kallak mine and added some links with further information: https://www.openstreetmap.org/changeset/180129364.
As there is nothing to be seen on the ground for now it's not useful IMHO to map any areas  for now. As can be seen in this https://www.youtube.com/watch?v=eej0wVVPfT0&t=327s video from the mining company, the poposed mine (tailings etc) will exceed the iron ore deposit mapped on the Wikimedia map dsp77 had linked just above.
Since this note is at quite another location, I will close ist now.
