Ann: Trial Mining Licence Update, page-57

(Just posted this earlier but seems to have somehow disappeared.)
If mining at the surface produces a promising amount of gold does that mean we have disseminated mineralisation?
Is it possible that the chips taken at the surface are not representative of the composition of the underlying rock?
For example could leachate containing mineralised gold percolate through interstices and deposit gold in the surface boundary resulting in the gold being concentrated there but NOT disseminated evenly?

BTW Im not trying to down ramp. Ive held most of my swag of BBX for over a year.
