Lots of good info but the following quote stands out:

"We are not only going to be an integrated mine-to-metal producer, but we are looking to be an integrated mine-to-metal producer of ferrochrome and PGMs out of the same orebody. On top of that, and it gets better, not only will we use the same orebody, but we will use the same furnaces. So, for us, its very compelling, Smit says."
