Ummmm, well its probably great value but with copper prices tanking, a war in congo, a congo government which won't finalise the mining reviews and no signs that the economy will pick up in the next 24 months, I'm not sure that this is the environment to be investing in speculative resource stocks.
Having said that, there is huge room for upside and could easily be a 20 bagger. What we do know is that grade is king and TGS have it, along with sound management. And highly unlikely price will drop under 7c.
However, I'd invest in Lynas (LYC). With China supply of rare earths diminishing, Lynas owning the largest deposit in the world in Mt Weld and Barack Obama promoting alternative fuel methods and green technology, there could be a huge market for rare earths over the next century. When Lynas start producing, expecting a huge re-rating.
