my fy13 revenue estimate, page-22

something positive for AGO holders, from Rio full year results of iron ore division:

Production was 198.9mt
revenue was $24.3b
underlying earnings was $9.24b

From this works out that RIO received $120/t from their iron ore, at cost of ~$75.7/t, margin still massive at $44.3/t. But rio cost is clearly not $30-40/t like most newspaper article say. Taking into account the fall in AUD rio cost is probably around $68/t now. Rio is the lowest cost producer in the world.
