40% of Rhodes Ridge is worth $5.3bn, implies 100% is worth 13.25 Bn. This is great news for Zanaga IMHO. A couple of things to think about.
Rhodes Ridge (Haematite) is 61.6% Fe. Pure Haematite [Fe2 O3] is 69.9% Fe (Fethe remainder is Oxygen). So Rhodes Ridide contains 8.3% Impurities.
Zanaga has Haematite at 66.0% Fe. Which implies 3.9% Impurities.
Zanaga has Magnetite at 68.5% Fe. Which also implies 3.9% Impurities (Pure Magnetite [FE3 O4] is 72.4% Fe)
So Rhodes Ridge has approx twice the impurities.
Rhodes Ridge is approx twice the size of Zanaga in terms of Iron Content (The Ore at Zanaga is about 34% Iron out of the ground before what is basically sand is separated [benefaction].
However, this does not mean that (other things equal) its worth twice as much. The value (i.e. NPV) is essentially determined by how much ore you can extract in 30 years, the fact that it can continue for much longer does not impact the NPV. For example if you receive $1 a year for 30 years NPV(10) is $9.43, if you receive the $1 for 60 years NPV(10) $9.97 ($0.54 more). (BTW $1 a year for ever = $10 exactly = $1/10%).
