# Core It is the only and last source of energy. Therefore, the ultimate task of humanity is to mine the core. Players gain access to the core after drilling through the 9th level of the depth through collective efforts. * The core has a limited reserve of DME. The core irregularly saturates its [Depth ](/deepmine/deepmine-entities/untitled-1.md)every day, forcing citizens to extract energy from the mines and dig closer to the core. * Players cannot access the core independently. * At least 10% of active mines must reach the ninth level to overcome the last level of depth and open [access to the core](broken://pages/-MhJzy_DmiySvPNvXRv0). * Upon reaching the core, players will need to develop an infrastructure to extract energy from the core and deliver it to the surface. * Core is the source of [Ejection.](/deepmine/deepmine-entities/untitled-1.md#ejection) ![](/files/-MhJslhT4kTo6_r4xPdP) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
