Ann: High-Grade assays from initial prospecting at Javelin, page-26

Avg annual production of ~33k tonnes Cu Eq
The US jurisdiction may not appeal to the Chinese, but it would appeal to a mid tier producer in Nth America.

I'd like to think $1 billion MC++ (AUD) wouldn't be unrealistic once market understands mine permit isn't an issue.
From here to there though there's more upside with extra clusters looking likely to be found.

As with all this the Cu price is the big wild card as having such a high grade project translates to gravy straight to the bottom line with increase in the underlying commodity price as the revenue increases and costs are well accounted for in the extra redundancy capex factored in.

Take it all with a pinch of salt as I'm just a punter guessing like everyone else.
