Where are the minerals stored in the Kambala space program?

the minerals of the kambala space program are stored in the surface asteroids. Two types of drilling rigs are required. The small one is MK1 model, and the big one is the size of a passenger plane. Before using the drilling rig, extend it and turn on the mining machine. After the rig is ready, there are three types of mineral storage boxes (fuel tank columns): MK1, Extreme Rocket and External. After mining, the furnace should be changed and divided into unit rent propeller fuel, liquid fuel, oxidant and liquid fuel+oxidant. Both the drilling rig and the converter furnace burn electricity very much and are easy to overheat, so it is necessary to stack several more batteries, solar panels and heat dissipation plates.
