The cool thing about this discovery was that this rover can only drill about 5cm into a rock sample. The new Euro Mars rover in a couple years will be able to drill 2 meters down. A much more significant distance. A distance where possible organic material would be much more well preserved.

Who knows? time is hard to judge, scientists claim if the earth suffered a cataclysmic event it would only take 250,000 years to wipe out any and all surface evidence of any life forms or structures. evidence seems to suggest Mars as a functional planet died about one billion years ago so any evidence of prior life advanced or not will be hard to find.
