FED.WT
I managed to buy the FED.WT warrants in my scottrade account (.48) but it sure wasn't easy- as I was the first buyer, they had to "set up" the symbol and they still struggle to get an accurate real time quote.
I paid less for my AAA shares, but I wanted the leverage here- AAA has blazed the trail in Ethiopia already. FED's chunk of land is huge, their finances are sound and the share structure is excellent by comparison.
Looking through their website, there's ample mention of takeovers in the jr potash sector and I think that's the plan here- to get the resource established quickly and sell the company to a big boy.
The warrants expire on 9 Sept 2012. It's possible IMO that the pre-feasibility won't be completed by then, but I'm confident they'll produce a NI-43 101 by that time that will show a massive amount of potash on their parcel.
Also, as has been mentioned and confirmed in an email I received from IR, they plan to list on the US exchange within a few months.
FED has already been a great runner since cartonet first mentioned it, but at current prices, there's still a long way to go before it equals valuations enjoyed by its peers.
