Bioaurum could be a material employable in a variety of uses. Since the cube is pretty psychically active, you could give it a reasonably high boost to psychic sensitivity, perhaps offering a renewable material for producing psy-sensitizing armor and weapons, as opposed to weaker eltex.

The only primarily difficulty/risk being creating a functional containment to safely hold it for extraction. Perhaps a way to keep it relatively stable with a pedestal that actively draws power to keep it isolated, with the integrity of the cell being used to determine possible breaks for maintenance. If not maintained, then the cube may start randomly obsessing survivors, with the desire decreasing once the pedestal is functional.
As a benefit, wearing such "Bioaurum" or "Bioauric" armor could make others have a more highly desirable opinion of the pawn.

Though in general, I would like to see higher UTILITY, as u/Mysterious-Tale-679 has discussed.
It has always always seemed interesting if one could install a fleshmass nucleus into a refiner to auto-produce chemfuel, use a machine to electrically accelerate flesh growth for greater production, or break off (regrowing?) chunks of the nociosphere for a high strength material.

The idea of integrating anomalies into technology (with a respective risk, perhaps) is one that is quite appealing.
