For a little while I've been playing around with developing excel models that value single-mine companies using monte carlo analysis. I'm wondering if anyone else has experience in this field or if anyone else has models they would like to share.
For me, I got into it thinking in ground value wasn't a sufficient measure. 'The Mining Valuation Handbook' by Dr Victor Rudenno has been a massive help. Also, I recently discovered an excel model (attached) by Prof. Richard de Neufville from MIT that's been an absolute revolution for me.
So, does anyone here try to build these models? If so, how do you go about developing your assumptions and what do your models look like?
