Cost Curves
----------------
The Copper, Lead, Zinc, Silver and Molybdenum cost curves have been
updated to incorporate these model revisions. All these cost curves are
now for 1998 to 2003 and contain conventional curves ranking costs after
byproduct credits, plus an additional set of curves showing rankings on a
strict co-product basis. Also included is a set of curves ranked on onsite mine
and mill costs.

Model Productivity Factors
----------------------------------
All base and precious metals models now contain adjustment factors in the Edit
sheet that allow users to change mine and mill labour productivity and consumables
usage rates, independently of the flowsheet and other settings built into the models.
This makes the models even more flexible since users can now "tune" the models to
match known actual performance or test various scenarios and look at sensitivities.
These adjustment factors are now being added to the Iron Ore models and will be available shortly.
