similarity with gwr

I have followed GPR and GWR closely lately. GWR listed in Jan 05, with a small Market Cap of Approx 15 Mill. It rose steadily and then rose 60% in one day and has continued to incline to a high of 2.30, and is now currently trading at around $2. The reason for this was a large concentration of shareholders, and very few shares traded. This leads me onto GPR. It has struck gold in its first drill hole at a significantly high grade. At a price of around 30c it has a market cap of only $8 Mill. Its top 20 Shareholders own over 60% of all shares - there are very few shares up for sale (ie the link with GWR).
This may be an interesting stock to keep an eye on - it has risen 40% in the last two days. With very few sellers, it may continue in only one direction?
