Adds a multiplier for the mining time to the options. At 3, it takes 3 times as long to mine a single ore. Ideal for that early game scarcity: you will need to find more patches to increase your mining/s!
Energy usage is compensated; it takes longer to mine, but the total energy spent is the same.
Should work in combination with many mods that adds mining buildings.
