Scale arithmetic. Hypothetical, own model, NOT a resource.
Conservative case: grade spread only ~120m from drill holes, inside a conceptual pit at US$4.25/lb Cu:
~133Mt @ 0.48% CuEq
≈590kt contained Cu (1.3Blb)
Main variable is that reach: at ~200m it is ~380Mt.

EV ~C$235M (C$0.92, ~C$20M cash): ~C$0.18/lb of conservative model Cu, with Piuquenes (Argentina) thrown in.
Next: 3,000m of assays pending, 2nd rig this quarter.
Caveat: own indicative model, not NI 43-101. CuEq = Cu + 0.000329·Mo ppm + 0.00704·Ag g/t.

In Nov 1963 one drill hole near Timmins cut nearly 600 feet of massive sulphide. Texas Gulf experts had never seen a first hole like it.
It became one of the world's great Cu-Zn mines - and the case that wrote US insider-trading law.

Production began in 1966. By 2016 Kidd had mined 140 Mt at 2.3% copper and 6.2% zinc - metal then valued around US$50B - and become the world's deepest base-metal mine, nearly 3 km down.
One hole. A giant VMS. And the rule that still hangs over every trading desk. 10/10
