Mining

Mining is a Expansion Period Science Card that grants Followers the ability to mine Gem seams.

Acquisition and unlocking
The card is acquired upon advancing to 1200 Followers.

Unlocking this card requires the use of stickers.

Usage
Gem seams look like shining golden leaves laying on the ground and may be buried. If necessary, dig out portions of a gem seam, and then guide Followers to it, who will automatically begin mining. Note that they may perform other tasks as well, such as building an Abode if there is an empty plot close enough. It isn't clear which they prioritize.
