Ann: Manna Delivers Increased Exploration Upside, page-15

I have no doubts that this great management team is already scoping out the economic point on when to switch to an UG option.

Lucky for GL1 they look to have many profitable years running an open pit mine before having to make the switch to UG based on the market at that time.

Also a larger pit that combines the existing scope pit outline and the new North Eastern pit (once its drilled out and defined) will drop the strip ratio for the first 5-7 years further improving the economics of this deposit.

Its a good place to be in and they look to have tonnes on the market just at the right time
