Looking at the current market caps for gold juniors ($5m to $20m seems to be the new market norm), I cant see TAO staying at $3.7m for much longer given:
Follow up results from 17g/t Au and 8760g/t Ag due shortly
Announced currently in negotiations for new projects
$1.7m cash and only 31m shares issued.
1 year 20c options being issued to shareholders should be in the money straight away (20c share price is still only a $6m mcap!)
