I've been watching these marijuana stocks take off like crazy and did a bit of research. Then I wrote to the office and begged them to find an old copper mine for an acquisition and grow pot in it.
It turns out that the copper in these old mines help promoted the growth of marijuana. There must be tons of abandoned mines out there.
It's kind of a crazy messed up world when the copper mines can give shareholders a better return if they grew pot in them, but there you go.
There is a company advertising on these boards called Bayhorse Silver. They are a junior exploration company operating in New Zealand and they hired some consultants to explore business opportunities in the medical marijuana business. They're stock went up 10%. They didn't even do anything, just talked about marijuana and up it went.
Then there is this company in Sakatoon that was exploring the idea of growing pot in an old mine and found that it grew quite well. I'm not really sure if they still grow things in the old mine but they call it a "biosecure growth chamber."
