Start Mining 2019 Copper, Cobalt, Zinc, page-29

Below is from July announcement, the bottom is 4th Dec. You can see how poorly tested the PY3 unit was at Vardy and West/East. With the new model, they drilled 4 holes into the guts of it to the West and got 20-25m @ 1.1%-2.4% Cu and 0.16-0.30% Co. (169m -288m). That's very consistent, and 900m West of that they hit a whopping 30m @3% Cu & 0.44 Co, the best result yet from the PY3 zone.

So PY3 is very high-grade, about 10-30m thick and possibly extends for up to 22km. What sort of tonnage are we talking?
