Ann: High-Grade Nickel Sulphides Confirmed at Dogleg Prospect, page-31

Yes BUX owns 16% + free carried (IGO is paying all costs of exploration) + IGO pays BUX cash as consideration for the earn-in (half a million paid today in respect to this hit alone) - do the maths, and consider that this leaves BUX free to concentrate on their 100% owned projects (Graphite Bull eg)
Think about 16% free carried to another Nova Bollinger !! And from IGO's recent ann, they have that very thing in mind. Todays grades are a stand out, in the future we need tonnes.

At the JV with IGO on Copper Wolf BUX has 20%, again all expenses to IGO - and given the second diamond drill went 600m below historical with mineralisation to EOH, we can expect any assay result >~ half % Cu, will be a bonanza for low capped BUX ($41 Million) and substantial even for blue chip IGO (Capped at $7.3 Billion).

I hold both - IGO, because I reckon CW is not factored in - but DYOR, I could get eggonface.
