Basalt rocks do not always deplete when ore is mined and respawn quickly. With a rune pickaxe and less than 80 Mining, 650–850 per hour can be mined. Attention required is comparable to the upper floor of the Motherlode Mine. The crystal pickaxe's effect does not work on basalt, neither does the prospector kit, celestial ring and derivatives.

Basalt diatomite is extracted by open-pit mining. The overlying waste material is ripped with a bulldozer, and then scrapers haul the waste to adjacent disposal areas. Once the diatomite bed is uncovered and qualified, the ore is then lifted with scrapers and hauled to corresponding stockpiles near the plant.

Despite being an extrusive igneous rock, basalt has a lower mining time than granite and diorite, which are intrusive. Basalt is the only rock-like block to have both a polished and smooth variant.
