Ann: MOD to Present at the World Copper Conference, page-5

When MOD make a swift decision to focus on a single target (as with T3 and now T20), I tend to think they know something and just need to prove it.
T3 was too compelling to move on to the other targets and this is the reason I am very interested in T20.

Sure they could just be playing the percentages but they recognised T3 was special very early.
If they are narrowing their spotlight on a single target next I think they must be pretty confident.
