Core Miner

The Core Miner is an advanced long-term mining drill, which consumes very large amounts of power to produce an infinite stream of mixed resources.

Production
The Core Miner produces Core Fragments, which are processed in the Pulveriser. The type of Core Fragments produced depend on the Primary Resource of the location. On Nauvis (no primary resource) the miner produces "regular" Core Fragments, which yield all vanilla ores and liquids and a little Vulcanite.

On locations with a Primary Resource, the miner produces Core Fragments of that resource, which are processed into: that resource, Stone, and a few regular Core Fragments.

Efficiency
The efficiency of Core Miners decays as more miners are active on a planet or moon, using the following formula:

Average Core Fragments per Second = (zone radius) / 500 * √ (number of miners) * Productivity Research Bonus

The Core Miner benefits from Mining Productivity Research, however it has no module slots and cannot receive effects from Beacons. However, the Pulverizers processing the Core Fragments can benefit from Productivity Modules.

Cost
The core miner has no other input cost than electricity; however, at 50MW, it has the highest base power consumption of any terrestrial building.
