Of course there is risk in everything. But examining risk is what gives you the "warning signs" you referred to... being non-chalant about risk in junior miners is not normally a wise way to approach the investment.
Anyways, the point of this thread was to highlight known risks and my thoughts on them. At the end of that post I mentioned I'm comfortable with all of the risks I'm aware of with AAA.... well except the dilution risk. This was looking like a 10 bagger until those warrants.
