I have my doubts about ERHC buying 50% of the shares.
OPUSx said he bought more as I did as well....chances it wasn't ERHC, do your own DD as I am not wrong about Opus x saying so and Me doing it also.
Chances are some old investors are buying back in as they see fit . For very little cash you have a chance to get your money back, IF, there are more positive developments announced,and occuring. All my opinion.
