▼ marks the lower resource / time cost. Cheaper isn't always better — weigh it against the effect each tech unlocks.

Improved Extraction

Increases all mine production by 10%.

Deep Core Drilling

Advanced drilling rigs increase metal and crystal yield by 20%.

Unlocks buildings: deep drill

Requires: mining 1

Which Should You Research First?

The Improved Extraction is the lower-tier prerequisite step and typically comes first in the mining branch, opening the path toward Deep Core Drilling.
