Target 3-6 cents high grade production going up, page-70

A1 has lots of disused historic workings that could be refilled.

I live in the States, and my last drive through Central Victoria got me a speeding ticket several decades ago.
I am not aware of the foibles that flow out of your local governments BUT I understand that there are a lot of unemployed gold miners and timber industry workers in Central Victoria.

You could possibly get away with a simple gravity circuit at the A1 mine and ship the balance to Maldon. A gravity circuit would not have any environmental issues attached, and cost would probably be around $5.0M.
