Yellow Minerals are a type of mineral in Spectrobes: Origins.
Their purpose is to give Spectrobes experience upon eating it. Yellow minerals give a Spectrobe 64 experience, twice as much experience as the Green Mineral. Yellow minerals are rare on Wyterra, but become more common as Rallen and Jeena travel to other planets. If a Child Search Spectrobe uncovers a Yellow Mineral while scanning an area, it gains 4 EXP.
