It's funny, I call these pre-revenue exploration and miner companies "scratch off tickets". You lose on most, break even on some, and the odd time you'll find a big winner. It seems like Bedford is one of the rare winners.
I will be the first to admit I spend little time researching these companies. It is not my area of expertise as I typically spend my time researching companies that are generating revenue/cash flow.
However, I will dig into it for you. You'll need to give me some time here though because off the top of my head, I do not know of one. Unless you are open to looking at a larger-cap miner, I do follow quite a bit of those. But in terms of nano cap exploration companies, I'd need todo some digging.
