Large Resource Deposits (Subnautica)
Large Resource Deposits are large quantities of a single Raw Material found in Subnautica. Unlike stone outcrops, the materials cannot be harvested by hand; instead they must be broken down using the Prawn Suit Drill Arm.

Trivia
- There is a 0.000000471431432% chance for a large Kyanite deposit to yield 22 Kyanite pieces.
- There are four Large Resource Deposit models that currently do not appear in Subnautica: the large Diamond, Ruby, Crystalline Sulfur and Mercury deposits.
- However, the Large Ruby Deposit and the Large Diamond Deposit were repurposed for Subnautica: Below Zero.
- There used to be Large Resource Deposits of Diamonds generated on the map, before raw resources got new models.
- Over the course of the development of Subnautica, the models for Large Resourse Deposits have often changed.
- Large Silver Deposits have been found in the Jellyshroom Cave, but it is unknown if this is intentional or a bug.
