Once in production this would have around a $1.4billion valuation based on todays market valuations. So a three year investment now is likely to yield somewhere towards a 100% to 200% return if they get it into production. There is risk attached to the project and time required but it's a significant gold deposit that is growing and history shows that gold deposits of this size don't sit in the ground for too long - they get mined. The other option is it gets taken out via takeover which is highly probable. In this case the return to shareholders would probably be in the 50% to 80% from this point. Not as good a return but it would come a lot sooner. Both cases are good risk/reward opportunities IMO but there is definitely risk associated with this type of investment. I have a lot of gold miners in my portfolio that are in production and whilst I expect good upside from them, none offer this type of upside in terms of percentage gains based on todays values.
