Common knowledge on site that the primary crusher as installed with two cones cannot crush at the required tph to feed the plant @ nameplate. Management were told that is was never going to work, it hasn't and it won't.

The latest quarterly report seems misleading.

Significant Events Post Quarter End
New Crusher circuit completed and operating consistently

Fact
consistently at what rate? "consistently" does not mean that the crusher meets the tph required to run the plant at nameplate (it's not even close)
The crusher hasn't been commissioned with native Copper so they couldn't claim it's even commissioned let alone say it's consistent.

Let's hope the Chinese-made quarry cones hold up although it is highly unlikely.
