1....I need to do some advanced calulations, to see if excavations
are even possible.




?
2....I need to know the average yearly rainfall
If you are talking about in Az., ?? Since you did not mention the area, The Avg. rain fall is 12" a yr!
Most of it falls in a couple of months during the "Fall"!
3....I need to know the ground cover type
Where is the Area ?
4....I need to know the average size of a small to medium size spanish smelter/type of material/and
weight ?
This all depends, if the Smelter is a "Mine" Smelter or a "Regional" Smelter?
Type of material? Of What ?
A "Smelter" is where the miners would crush the ore, extract the gold/silver and melt it into bars/ingots!
If they had the available fuel etc..
Normally a "smelter" is built of a rocks, adobe, etc..!
5....Do you have access to blasting materials {Im not Doc Noss}
YES!
I would need a lot more information to be exact !!!
ie:
If the smelter is in the mnts.. ?
The terrain is going to be ROCK! Solid Rock!
If the smelter is in the "flats/valley" very hard & cemented soil
Etc..
BUT!
IF YOU ARE going to be "GREEDY" YOU CAN FORGET THE WHOLE DEAL !!! [/glow]
