RE: DIY DrillingGood questions. My take is that MRZ is already priced at $90mm by the market. At that price, the market is already assuming that MRZ has something good. I hope they will eventually be able to sell their Joaquin stake and use the proceeds to carry Virginia through to the feasibility stage; that's the money-maker IMHO.
I'd guess MRZ is 4-5 years from mining anything profitably.
