* Survey conducted shortly after start-up

Ore characterization:
* Monzonite ore type,
** WiC = 16.5 (metric)
** WiRM = 19.0 (metric)
** WiBM = 17.1 (metric)
** A×b = 36
** DWI = 7.5
** density = 2.7 t/m³
* SAG feed is primary crushed to F80 = 98 mm
* Ball mill circuit product P80 = 170 µm

SAG mill characteristics:
* Diameter inside shell = 12.2 m (40 ft)
* EGL = 6.1 m (20 ft)
* Ball filling = 12% v/v
* Total filling = 25% v/v
* Mill speed = 78% of critical (Lane et al, 2013 appears to have a typo. They claim 72% which actually looks like the BM speed)
* Pulp density = 70% w/w

Ball mill characteristics:
* Diameter inside shell = 6.7 m (22 ft)
* EGL = 11.3 m (36.5 ft)
* Ball filling = 30% v/v
* Mill speed = 72% of critical
* Pulp density = 70% w/w
