Ann: Highlands declares maiden Resource at Star Mountains, page-4

Olgal resource is Actually 210 million tonnes at 0.4% copper for 840,000 contained tonnes of Cu and 2.9Moz gold.

Rough gross metal value (USDollars):
Cu 0.84M tonnes at $7k per tonne => $6B
Au 2.9M oz at $1.3k per oz => $4B

$10B is nice size to plan for, though I would prefer a better Cu grade to justify investment.
