All they do is give 1 extra ore on every ore-receiving swing, letting you double the rate at which you get ores as long as you have stone spirits, and fully AFK lower level rocks at peak efficiency as long as you have a Perfect Mining Juju potion active.
as an ironman, the problem i have with stone spirits is that they replaced the previous ore drops at a 1:1 ratio from bossing, the idea of stone spirits its fine... IF THEY are dropped from level appropriate monsters, but 50 runite stone spirits is not the same as 50 runite ore anymore.
50 runite ore to an ironman is 600k worth of rune to high alch (i would make rune sq shields and get 12k ber bar) 50 stone spirits? well i have to mine the ore first and then smith it, and the end product is worth about 500gp per bar, for a longer process (sq shields alch for 1k now) so to sum it up, on top of being reduced in value to 1/24, this is also not a direct ore drop you actually have to go mine it, decreasing the value even further...
i plant wishing well bushes 3 times a day...........now getting stupid spirits instead of ore or bars. I have 99 mining and smithing............hate the update. can only smith 1 thing at a time then have to keep clicking. only thing i mine is the glass to make flasks 4 crafting. used to fill an urn each50 mined. now on 77% fill for the 50.
