Going from manual mining to grinder operations is too big of technology leap. manual mining is a pain with Jackhammer1 and the out put is only a very small portion of only one material. This technology advancement would make more sense if you get all material in slow manualy grinding, and with every level of automation the %yield decreases at the benefit of automation. You did a nice job on the soldering minigame, why not make a mining-minigame where if successfull you get more material
