im a bit concerned, page-40

You may be onto something, I'm looking at these drills and I can't find any grade, at shallow depth that gets over 3.12%. It hits 6% at around 50m, but before that max is around 1.7%

Anyone with more knowledge than me (i know nothing) care to clarify, how deep you would drill each year?

Good question malmanu, I will trying to research more, if no one can answer the question.

Hopefully some people with mining experience can clarify.
