Research Underground Mining

Research Underground Mining is a research project that unlocks underground mining-related progression in Foundry. It is a straightforward early research entry with a modest cost, and its only listed requirement is the standard research cost payment.

The research cost shown for this project is 50, 50, 50, 50, plus 60 seconds of research time. No additional prerequisites or special conditions are listed in the available source.

Because it is part of the research tree, it is best treated as a setup investment rather than an immediate production upgrade: complete it when you are ready to expand into underground extraction and want to keep your research queue moving efficiently.
