the short-sightedness of this deal, page-42

H (haemitite)

If you want to discuss thing's,please do so without being rude.
I quoted directly from Google on Quartile. Business.com.

Just look at the chart you have posted and are saying points to SDL being third quartile and expensive.
SDL shown as the lowest cost for DSO.
Sundance is the second lowest cost for Itabirite or Magnetite type iron ore that is converted to Concentrate,DR,Pellet Feed.

Two entirely different types of iron ore,with entirely different grades and selling prices.Higher price attained when selling iron ore starts with Paraopeba Complex.
Paraopeba Complex is in Brazil and is sold as Concentrate and Pellet Feed. They are shown as lowest cost with SDL next lowest cost. Concentrate and Pellet Feed can bring a price $20 to $40 per tonne more than 62%Fe DSO.
Cloud Break and Christmas Creek Fines come in a lot higher cost than SDL's Concentrate and Pellet Feed.

Hope Down Lumps and Fines come in at $30 per tonne,with SDL's Concentrate and Pellet Feed at $40 per tonne,but SDL expected to fetch $20 to $40 more per tonne than Hope Downs Lump and Fines.

Who is muddling basic maths?
Not back peddling over anything.

Still waiting with others for your reply to our questions on comments you made from a couple of days ago.
