Regarding Rick Rule's comment, "The increase in value that we are seeing between preliminary economic assessment and bankable feasibility study is really tremendous."

Let's hope this observation applies to Tyhee's PEA v. FS, since its PEA was very promising, and in some ways more promishing than its Prefeasibility Study. For example,

Tyhee's Prefeasibility Study calculated a yearly production of 108,000 ounces at a cost of $546 per ounce.

Whereas its PEA projected a 163,500 ounce per year mine with a cash operating cost of $384 per ounce.
