There is no way of knowing which goldie is the best to have. Aussie goldies based in potentially strife torn foreign countries currently producing at cheap asic could crash and burn in a second.
Aussie goldies doing exploration stage could hit the elderado of gold veins and shoot to the moon or turn up empty.
Company XXX is the best, I'll put everything on that is fraught with danger.
No debt, expanding out put and exploration upside potential has derisked SLR to a position worth have some exposure too I believe.
At the end of the day, use HC to get a view on a list of Goldies that interest you but DYOR on them and invest in the ones that meet your personal risk/reward ratio.
I'm a LT holder of SLR who averaged down. 60 cent become green for me.
