Two rotation ideas show up in the material, and they should not be mashed into one invented schedule.
The experience description states a new Antarctic mining zone every hour. It does not name the zones, say whether the previous zone closes, or say that crystals reset. Any page that prints a full named zone roster is ahead of the official text.
Separate guides describe a Mountain RNG button at the bottom left. It lists mountain types. Rarer types are described as carrying better crystals. The same guides say that once your warmth can handle it, you can climb the outside of the mountain, skip the low flank, and start mining at the altitude you want, so a good mountain is not wasted on the climb up.
What to do on the hour
- Open the zone information in your server after the hour.
- Also open Mountain RNG if that button is on your screen, and read the current mountain type.
- If warmth can hold the high band, go there. If not, mine a safe band and spend the Cash on Climb Higher.
- Sell before the next hour if you want the bag empty for whatever arrives next.
There is no official preview of the next zone. Logging in just after the hour gives you the longest look at the zone that just arrived. Missing an hour does not brick progress: another zone is scheduled to arrive on the following hour.
Hidden treasures are official. The description says you uncover them while mining. What they pay, and which tool reveals them, is on the in-game prompt. Radars are the consumable guides associate with finding buried targets. See the bombs and radars guide before you buy one.
