From my experience you don't hold a junior resource company until production stage because thats when they start to destroy value. One of my mentors has written a chapter in an investment book about the mining company value curve - share price goes up on resource discovery/acquisition, then goes down on capital raise/funding, goes up on development plan/investment decision, peaks somewhere thereafter (SELL/get out) and then production starts and share price starts a steady grind down (production is dull and fraught). Look at SYR, they're not even producing yet and look at what's priced in - massive boom in the share price, $1.2bn MC and no production, SELL that one because the upside is priced in. In my experience, you've got it the wrong way around - this company is just about to start creating value, its done the capital raise and moving into development = the leg up in share price.
NB I usually botch my entry too and end up buying too high and have to average down if I still like the stock. In this instance I'm at 6c/sh. This will be 30-40c/sh within 12 months IMO, but thats my opinion based on my experience and I have put my money there.
You might be unique in that you have something that works for you from your experience, thats great, if it works for you, it works for me too, but the investment in BAT is as close to a no-brainer as I have seen. I'm cool with your decision to exit, but I reckon its therefore best to move on. We won't begrudge you a bit of an exit spray though, hope you feel better, thats what this forum is for, I just wish your spray wasn't the first response to the announcement, haha,
