sbl vs adu

I have conducted a brief search on ADU as they are another gold player in Ghana and are also on SBL presentation. ADU are also forecasting to produce and move forward in Q1 2011 as a 100,00oz Gold producer pa. They also seem to be building a plant. They also seem to have indicated and inferred 17 million tones,where SBL Have 19.6 Grades are not to far apart. The GAP I can see is shares on issue ADU 381 MIL vs SBL 1.2B though what i am a little perplexed with, is that SBL is trading at 0.02 and ADU is 0.64 ?? Can anyone shed some light and do we have this type of potential in share price ?
