Make a bet on cobalt, page-6

Motley fool has recently covered TGS, Its actually a positive report.

Tiger Resources Limited (ASX: TGS)
This copper miner recently completed a viability study investigating the cost of adding a cobalt recovery circuit to its Kipoi mine in the Democractic Republic of Congo (DRC). Further details are expected in the near future, but Tiger is sitting on an estimated 40,000 tonnes of cobalt, while a recovery facility has an estimated cost of around $22 million. This is significantly cheaper than the options available to several other would-be cobalt producers.
If it makes economic sense, adding cobalt capability would be relatively simple for Tiger, which already has an established mine in the region. The downside is that Tiger would have to raise capital or take on more debt in order to fund the facility, and the company already has a hefty debt balance; interest payments alone are crushing the company’s profitability. Tiger is a very high risk venture in my opinion, but more attractive than some other cobalt companies which are either years away from production, or have only a minority interest in their cobalt tenements.
