Please not the difference between 'resource' and 'reserve'.
Project economics will determine how much of the 60,000t of contained copper is recoverable - a step a long way off.
I am also a bit suspect to how they have reported the Koonenberry resource. Notice even the 'inferred' category is reported to the nearest tonne. JORC stipulates numbers should be rounded to reflect uncertainty - and why they bothered to report Au, I don't know.
