Astroneer - How to get enough copper ore and aluminum ore?

Solution 1:

I was given bad info before I began playing this game. My best friend of 30 years told me that the ores only spawn inside mountains. This isn't true and now we are enemies forever. I will never forgive him, ever.

After briefly mourning this sad incident, I discovered that you can simply dig a long way downwards to find it! Carefully descending into the ground at a shallow angle (so you can walk out again) will sooner or later bring you out in an underground cave system and chances are there will be at least some Laterite (aluminum ore), Malachite (Copper ore) and probably a decent amount of oxygen and energy (which makes it easier to explore faster).

I suspect that a seriously organised "open cast mining" operation centered around your home base will yield very large amounts of metal ores, hydrazine and other goodies. If you have rover or truck already, then you can use that as a portable base (remember to fill it up with solar panels and storage racks).

Solution 2:

I dont know about alumininum but copper can be made by putting malicite in a smelter. you can find malichite in caves
