It's clear that not everyone made the win on RVD as they would have liked, I would suggest checking out Eagle Star Minerals Corp. EGE.V....The only other Venture listed company with a focus on phosphate in Brazil and if you have a look at their recent press releases you will see they are hitting the same type of high-grade as RVD..The difference may be that it sounds like they will have a resource much larger then RVD with a market cap much lower!.  Its worth a look and like always do your own DD..
