Drill a Promethium deposit
Promethium is a power resource, and drilling a confirmed underground deposit can provide a larger collection opportunity than…
WHERE & HOW TO FARM
Drill a Promethium deposit
Planet map resource list → Promethium availability; then follow a detector marker to a confirmed underground deposit.
Before you go
- Planet whose resource list includes Promethium
- Resource detector
- Handheld drill suitable for ground drilling
- Biofuel for drill ammunition
Farming steps
- Open the planet map and check the resource list for Promethium.
- Equip or carry a detector and explore until a Promethium deposit marker appears.
- Approach the marker and verify its displayed resource type and remaining information.
- Load Biofuel into the handheld drill and select Ground Drill mode.
- Begin digging at the deposit, keeping the tunnel angled toward an exit rather than making a straight vertical shaft.
- Collect the mined Promethium and check the deposit information as you work.
- Return to the surface and store the ore for the power-related crafting need you are addressing.
- Use Ground Drill mode for the underground deposit; Rock Drill mode is intended for surface rocks.
- Keep an angled route back to the surface so you can exit the excavation.
Repeat, collect and use
A deposit has limited remaining material. Continue mining while the deposit still has Promethium and you need it; use the detector again to locate another deposit if the current one is depleted.
Common mistakes
- Searching for deposits without checking the planet resource list: confirm Promethium is available first.
- Using the Survival Tool Rock Drill on underground terrain: equip the handheld drill and select Ground Drill mode.
- Digging a vertical shaft that is difficult to climb out of: maintain an angled route toward the surface.
When to stop or switch
Stop when the deposit is depleted or you have enough Promethium for your current power plan; leave by the prepared route and switch to another confirmed deposit if more is needed.
