Baires2,
I suggest that you add to the list of reasons the following quote by Mart Rosner....
"what makes Tyhee's gold ounces so appealing is the fact that these types of deposits are usually mineralized to depths of at least 1,000 meters, so that the likelihood of the resource size increasing dramatically over time will allow the marketplace to attach a higher value per ounce on the current Tyhee resource"
