In Spiritfarer, Stella can mine with the help of her Everlight.
How To Mine[]
Stand next to the ore and hold your interact key to charge up the Everlight. Be careful not to hold it too long, or it will fall behind Stella and you will have to wait for her to pick it back up. It is ideal to release the pickaxe just before it overcharges, or just after it begins to flash.
Some nodes take multiple strikes to break.
Hidden Treasure Chests[]
In several of the mines, there are treasure chests that can only be accessed by walking into walls. Most of these hidden passages are marked by the lights in the mines.
Follow the wires into the hidden walkway.
The treasure chest will be on the other side.
