Astroneer - Sphalerite

astroneer sphalerite

Sphalerite is another one of those natural resources in Astroneer that sounds made up but in fact, it is actually an ore that exists in the real world and is used as a source of Zinc in real life as well as the game.

It is a fairly uncommon resource that is found in caves. It can be found on the starting planet. If you explore enough, you are bound to find some early on in the game.

Where To Find Sphalerite

Sphalerite is found in caves beneath the planet surface on Sylva (the starting planet) and on the mountains of Desolo. It is uncommon to find but not that rare either. It is quite distinct in appearance as it looks a bit like a cracked shell with some smooth curved areas with other more jagged parts that look like it has broken apart.

Since this is a planet specific resource, it is not possible to obtain this resource using a soil centrifuge. If you are stuck for some, you can obtain it from a trading platform if you have progressed this far in the game.
