PQ owns mostly GHDC, but the rest of the gang own lots of both. One of them told me he bought a boatload of SFMI for his mother (or had her buy them).

I think the reason that PQ has more GHDC is that GHDC is more of a royalty company- just collects the checks. I know PQ planned to turn over SFMI to someone with mining experience once the company got going. I think PQ may have planned to "phase in" his retirement by handing over SFMI, and then maybe just running GHDC (which should be more straightforward and less taxing), and later (or at the same time) turning GHDC over also and just collecting the checks... All JMHO, of course.
