RE:COMMUNICATIONS WITH E79I wouldn't sweat it.
I emailed them twice and nothing back either...
That being said I'm sure Kirkland Lake got through right away to congratulate them and offer any help if need be. ( just business )
Lots of companies suck at communicating.
These guys should be busy as I believe they got more then one stellar hole to expand on. ( super high grade )
we shall find out soon ,
all the best
