Ok so i tested it again, and there are patches far outside of my base, that are containing ruby spots. Copper and gold also. Lets say, on a 3-4 kk patch of copper, there are 3-4 spots only that containing copper and ruby also. if I set the recipe of a Depo to Copper and Ruby, only that 3-4 drones fly out to mine. If I plop an another depo with a normal copper recipe, they mine normally, but dont mine ruby. Also the copper/ruby spots containing copper also, in a rate of 1k copper and like 30-40 ruby. That 3-4 drone, also mines the copper in them, so actually I need 10-15 minutes, to get at least 1-2 ruby. Is this normal? I thought this works something like Kovarex, that U have a chance to get copper or ruby.
