Establish Osmium extraction in the Prime ice cave
Turn the Prime Osmium cave into a continuing source for advanced crafting.
WHERE & HOW TO FARM
Establish Osmium extraction in the Prime ice cave
The Prime ice cave north of the escape pod landing spot, near 404:142:996.
Before you go
- Advance Heat until the cave ice melts.
- Collect three Osmium chunks by hand for the extractor recipe.
- Unlock T2 Ore Extractor at 364.5 mPa pressure and gather 3 Osmium, 1 Super Alloy Rod, and 2 Iridium Rods.
- Provide power for the extractor.
Farming steps
- Travel north from the landing area to the cave near 404:142:996.
- If the entrance is frozen, continue Heat terraforming and return after it opens.
- Enter and collect three Osmium chunks by hand.
- Reach the T2 Ore Extractor unlock and craft it from the listed materials.
- Place the extractor on the cave’s ore vein and connect adequate power.
- Return to the machine’s output, collect Osmium, and store it for crafting.
- Confirm the vein and displayed extraction eligibility when placing the machine; do not rely on coordinates alone for placement.
- Budget the three hand-collected chunks for the extractor before spending them on other recipes.
Repeat, collect and use
After setup, the extractor provides an ongoing supply while powered. Collect its output as needed; the initial hand-gathered chunks are a limited setup resource.
Common mistakes
- Attempting this with T1: the documented Prime Osmium setup uses T2.
- Spending setup Osmium before building: reserve the three chunks needed for the extractor.
- Placing the machine off the vein: position it on the ore vein and verify its output.
When to stop or switch
Keep the powered extractor while Osmium remains useful; switch to another resource site if power or output storage is limiting production.
