I cover this company whose shares were up by 500% at one point today. Does Synairgen (SNG) really sit on a gold mine? I also look at 3 David Lenigas related situations: Empire Metals (EEE), Pires (PIRI) and UK Oil & Gas (UKOG). With regard to the last of the three I mention Jubilee Metals (JLP), in which I bought some more shares today. I also discuss the “it’s too good to be true” rule ref Amigo (AMGO)
