Richard,

That is a very interesting paper. Too bad that most of it does not apply to Maxam. They don't have a traditional placer deposit, remember. If they had a traditional placer deposit they would not need vibra mills or some of the other fancy stuff. They would also be able to consistently fire assay material. Don't you remember that they were going to recover everything but the squeal. Like I said, most of the info. presented is accurate, but it applies to a traditional placer deposits.

BTW, all the reference's to Hewletts papers, he did some very good work back in the 60's when big main frame computers were being introduced for ore reserve calcualtions. They were applied to low grade open pit copper which was the big thing back in the 60's. Once the Carlin type deposits took off in the 70's, a whole new generation of programs, software, computers, engineers and programers took over. In much the same way that no ones uses stamp mills for gold processing, no one uses ore reserve models from the 60's.

Tim

Seems Hewlett is longer in the tooth than I thought :-(
Think he should be replaced by a Champion?
