Silver Ore

Silver Ore is a raw material found by breaking Sandstone Outcrops. Its in-game description notes that it is a highly conductive material. Silver is required for making a number of electronics, though Sandstone can sometimes be hard to find. Silver Ore can be found as a large resource deposit, which can be easier to find than Sandstone and yield more resources.

Trivia

 * Despite the PDA dialogue stating a "Silver-based Computer Chip is an essential component of the Habitat Builder", the latter's crafting recipe uses just a normal Computer Chip which is crafted using two Table Coral Samples, Gold ore and Copper Wire, with no Silver involved.
