RE: blue sky
Ecuador is the new Nevada...There seems to be lots of gold everywhere in Ecuador (DMM has over 5 million, IAM Gold has a few million etc.)and the country is still in it's infancy as far as the mining industry is concerned.
It's very likely that ARU has several more millions of ounces of gold and silver on their many concessions.
Lots of blue sky potential may be an understatement...
