Iron Ore Boulder in Forgotten Ruins

An Iron Ore Boulder found in the Forgotten Ruins.

An ore boulder is a large shard of ore that contains 1,800 raw ore.

In order to harvest these boulders, a Crude Drill or Drill must be placed on any of the boulder's sides, which will then need to be connected to an electricity source. Multiple drills can be placed against the boulder's sides, increasing the rate the ore is harvested. A maximum of 8 drills can be placed against a boulder; two on each of the four sides.

The rate at which ore can be extracted from a boulder is 0.5–2.0 per minute over the course of 15–60 hours, depending on the amount and type of drills on it.

Once the drill is powered, the boulder will start shaking and making a *clink* noise with each hit. After the boulder is depleted, it will break and disappear.

Ore boulders are visible on the map as 2×2 squares of a single-color.

There are 8 types of ore boulders in the game, one for every metal ore.

    • 0.5.2.0-b84a: Ores from boulders now spawn in a random position inside the boulder, so having multiple Drills on the same boulder will not always yield ore from the same Drill.
    • 0.5.0.0-9b96: Added Galaxite Ore Boulders.
    • 0.4.0-3f9c: Added Octarine Ore Boulders.
    • 0.3.0-297a: Added Scarlet Ore Boulders.
