Well they finally got me to look at the 43-101. But again, I'm not mining literate but am a huge fan of logic.
They keep leaving off what comes after the "promising" part. USPR's expert geologists go on to say after that...
"19.1 Potential Risks
Because of the apparently fragmentary nature of the veins, a risk exists that insufficient information can be collected to demonstrate continuity of the veins below the surface over large enough distances for an economic reserve."
The focus should be on insufficient information to demonstrate an economic reserve, not on promising.
This post is my opinion and should not be used as investment advice.
