This is the "speculative" part of our investment portfolio. It is less than 4% of our total. They are not all in mining of precious metals. We have had losers, but also many doubles, more than 6 triples, a few up 400 - 700%, and one already in the past 6 months up over 1,100%. I enjoy researching small companies.
The 96 + % is invested prudently.
Thank you for your concern.
