No I am saying the sulphide  ore which is the   one in the photo has the gold locked up in the sulphides .
I mined the rich ore at the end of the 8 level which looks like the ore specimen in the photo 
We  could not treat the ore in   Waihi  so  we took it to Australia ..
They may be trying to treat ore from other  parts of the mine .
Google  treating massive  sulphide  ore .
Normally they roast it.
As I said good luck .     

Thanks Crackity 
We used to live in Waikino 
I wanted to buy the pub there but her in doors put a stop to that.
I hope it works out for you guys 
There was some good ore   between the 9 and the 8 level right at the end of the 9 level from  memory .
