The big play on precious metals mining stocks is that production costs remain (much) smaller than the metal's spot price
For gold - the cost to produce/mine 1 oz is roughly $2000. Then, those same miners sell it for more than $4000. Instant >$2000 profit per ounce (again, rough numbers) π
So from the current levels, assuming production costs increase less than the spot price of the metal - miners win big. I believe this will be the case.
