RE: Santa Fe was reported greater than 5 km (histo Why are they still operating the mill at 200tpd? If they have lots of gold and silver, it would make sense to operate the mill at 300tdpd. This would reduce costs and increase production. They upgraded to 300 tpd and gave it a test years ago.
The mill expansion, to 300 tonnes per day production capacity, is complete other than the acquisition and installation of liners for the new ball mill and the building of some piping and launders. It is anticipated that production at 300 tpd will be reached by mid 2010.
