One option might be for KWG to buy SPQ's former share in BD, bringing their (KWG) holdings to a majority share of that deposit, which would allow KWG to develop a mine there, and CLF could either keep the remaining minority share of BD plus their 100% ownership of BT, or sell those to NOT or another bidder.

The advantage for CLF would be some cash right away, but also part ownership of a working mine, if they kept a minority interest in BD.

Obviously KWG could neither buy at least another 21% of BD, nor finance mine development without serious backing. That could be with a hands-off steelmaker who might want a guaranteed supply of ferrochrome &/or chromite.
