"Andy Well is a no-brainer, its oxide and at worst free-milling with a lot of gravity recovery - its the second richest open pit in the world. "

Think you will find Andy Well now is an underground mine with fresh rock not oxide , initially there was an open pit that would have had oxide and transition ore
You are correct there is still ore underground , Junk did not leave it because he was concentrating on Deflector , you can go back and read the ASX announcements why it was abandoned .

As always , probably best to do some research before posting misinformation.
