Problem is there holdings are all in junior mining companies and earnings come when they unload shares that have increased in value. It's far from a steady source of income. Kind of hard to calculate value based on P/E .
What they do have at the moment is a huge assortment of juniors that have increased dramatically in value and they leverage investments. When they report market value as of Oct 31st it should open some eyes. That in my opinion is why the share price shows marked improvement.
It's going to be a bit volotile and maybe always will be. Personally I'm looking for a bit of a pull back this month to buy but while cheap it's not where I want to enter, if I can. By end of year should be well over $7 imho.
