Thanks for all that great info. I am beginning to get an understanding of the processes involved in the plant, and the variables that affect the processes and the costs.

In your previous post you said,"Biooxidation has yet to see a major project with proven economics although you always hear about trials."

What about Wiluna Mines in Australia which is producing at $323AUS, cash costs. They produce about 120K oz.s/yr.. with head grades to 8g./ton and, 88% recovery. They appear to be getting pretty good at the process, which is described at:
oberon.com.au

The cost figure is from Great Central Mines last quarterly report, period ending Dec 31,1997.

Sincerely,

Al Cern
