RE:Confused Wetcoatwanker
As usual you are confused and posting wrong numbers.
It appears you struggle reading so I will keep this really simple for you.
1. The importance of from surface.
2. Simply multiply meters by gpt to get gram meters per ton the compare. Snowline like 800 from surface vs Sitka at 240 from depth ie 300 to 400 % better and cheaper to mine.
