According to today's article on Silver Investing News, Sprott is recommending that silver miners buy silver to increase the price of silver, thus increasing investor interest in their companies. http://silverinvestingnews.com/9711/sprott-reinvest-miners-earnings-sii.html
Isn't that sort of like car manufacturers making and then not selling cars in order to increase the price of cars? Would that make car manufacturers more attractive to investors?
I'd suggest the more traditional, if boring route of paying dividends. That tends to attrect investors also. And, being silver bugs, the shareholders could then go and buy physical silver, increasing the silver price.
But that's just me. Eric Sprott is a much better investor than I am. I just think this idea is a little bit out there.
