I'm not an expert but you know who is... James Rasteh.
His interview with Raoul comes out tomorrow. Raoul and Rasteh really get into the weeds. I found it fascinating, and if you want to learn about gold mining stocks, this is the interview for you.
EDITED: James Rasteh discusses Jaguar Mining Inc (JAGGF) and TMAC Resources (TMMFF). Both are highly complex situations so I would definitely check out the interview before making any decisions!
Here is the interview:
