New Models
----------------
The following new models are now available.

El Toqui (Ag, Au, Zn)
Huaron (Ag, Cu, Zn, Pb)

The database now contains production info for these mines to year 2000.
We regret the necessity of restricting the free production data to year 2000, however some organisations
have been collecting free data from minecost and re-selling it in their expensive databases!
Complete production data is of course in all the minecost models.
