Aloha Ahlan, yes I too enjoy Matt's picks and have also made $$ on the golden triangle in BC.
Regarding David Heydon, I've done enough research to piece together the history. I assume the company you're referring to is Deepsea minerals. I saw references to a non-compete agreement with NUS; is there any info available on that?
Based on the timing of his departure from NUS, I'm guessing he wanted to cash out "at the top"? Or were there other more nefarious reasons?
