Mining Engineering...CSM vs University of Arizona

Got UofA acceptance today and as OOS received $16K - this lowers the COA to $38K.

Mines has been my mental first choice. If I get in I should qualify for the $12K for OOS - this lower my COA to $45K.

I do not have an in-state mining engineering program so it is OOS or abroad (Canada/Australia) for me, and I will not qualify for any additional aid. Arizona has a student mine and simulators software etc. For the mining engineering program is CSM worth the $7K annual difference?

Any students or grads who can help me through this medium sized cost/value difference will be a big help.

1 vs #19 world wide.
