Unlock access to a named Osmium source as Heat terraforming progresses.

WHERE & HOW TO FARM
Where to farm
Cliffs Ice Cave at HUD coordinates 396:144:992 on Prime.
The Cliffs Ice Cave contains a route to Osmium, but the entrance is frozen until Heat terraforming melts the ice. The stated threshold is 100 nK. Once the barrier opens, enter and collect accessible chunks by hand. This is a collection run, not an extractor setup; plan a later return if you want to establish automated production.
Reach the cave coordinates and carry oxygen and water.
Advance Heat terraforming to the cited 100 nK melt point.
Bring inventory space for Osmium and other cave finds.
Travel to 396:144:992 and locate the Cliffs Ice Cave entrance.
Check the Heat terraforming value before making a dedicated trip; the ice blocks access until it melts.
Continue Heat progress if the entrance remains frozen.
Return once the barrier has opened and enter the cave.
Collect the accessible Osmium chunks by hand.
Carry the ore back to base and store it for recipes or extractor construction.
Farming tips
The Cliffs cave is one named Osmium source; a separate Prime cave is reported north of the landing area near 404:142:996.
Do not confuse the cave entrance coordinates with a guarantee that every visit yields a particular amount of loose ore.
Repeat, collect and use
You can revisit to collect any remaining accessible chunks, but hand-collected cave pieces are finite. The cave itself remains useful as a location for a T2 extractor when eligible.
Common mistakes
Traveling before the ice melts: check Heat progression and return at the listed threshold.
Expecting this collection method to renew itself: use a suitable T2 Ore Extractor for steady production.
Leaving without checking inventory capacity: make room before entering so valuable ore is not left behind.
When to stop or switch
Finish the hand-collection run when you have the available chunks or your inventory is full; switch to T2 extraction when you need continuing supply.
