Yes, but it will still take time to produce even a small army of archers, look at our numbers:
3 warriors
1 archer
1 spearman
How many archers do you think will be necesary to not only attack, but to take their capital (on a hill). 12 turns is suficient to build an army, but that goes for the aztecs as well.
Yes, they need to conect the ore to their capital, but we do not know since when they have had this knolledge, they could very well be producing them now. Even a small group of jaguar warriors can take down our warrior units, not to mention archers. We must scout their lands...even if it means getting kicked out...Monty is polite, we can take that risk. But diving head first into a war with the aztecs without knolledge of their military might is something I am not willing to support.
