frieda vs yandera project economics

This is an interesting comparison.

Dont get me wrong, i know at this stage anyway Frieda River has over 3 times the resource of Yandera. But have a look at the other numbers below:

Resource Base
Frieda: 1900mt @ 0.45% Cu
Yandera: 775mt @ 0.35% Cu

Project Life
Frieda: 28 years
Yandera: targeting 20 years

Project Commissioning
Frieda: 2017
Yandera: 2014

Project Cost
Frieda: $5.3b USD (lots of infrastucture cost)
Yandera: app. $1.5b USD

Production Profile
Frieda: First 8 years @ 60Mtpa for 246,000tpa of Cu and remainding 20 years @ 50Mtpa for 190,000tpa of Cu
Yandera: 25Mt ramping up to 50Mtpa for app. 175,000tpa of Cu

Cash Cost
Frieda: app. 50c/lb (incl Gold credits)
Yandera: app. 90c/lb (incl Gold/moly credits)

As can be seen above, Yandera compares quite favourably against Frieda River. Theres no doubt Frieda is a larger project, but the envisaged annual production rate of Yandera is not that far off Frieda River, if anything they are actually the same at 50Mtpa. If you look at the project cost, this is where MGO clearly has the upperhand, 5.3b vs 1.5b is a big difference considering the difference between their forecast copper production not much @ 190ktpa vs 175ktpa.

Which would you rather invest in?

Discuss.
