Look for Erythrite Crystals in Hagga Rift, especially inside CHOAM Mineral Extraction Facilities. Cave systems, tunnels, facility entrances and other spots across the Rift are also worth checking. A route guide published in June 2025 points to an eastern tunnel approach near Vermillius Gap and Riftwatch, but that route has not been verified as the best option for the current game version.
Where to look for Erythrite Crystals
CHOAM Mineral Extraction Facilities
Start inside CHOAM Mineral Extraction Facilities in Hagga Rift. They are the most consistently recommended places to search, though the available sources do not establish which facility has the highest yield. Deposits may also be found near facility entrances. The community item reference and the game database both point to the Rift and its extraction facilities.

Caves and tunnels
Check caves and tunnels as well as the facilities themselves. A June 2025 PC Gamer location guide describes entering from the eastern side near Vermillius Gap and Riftwatch, then following an underground tunnel; it says deposits begin appearing about halfway through. Treat this as a route lead rather than a guaranteed current route or yield.
Other Rift locations
Erythrite can also appear elsewhere across Hagga Rift. If a facility or tunnel is empty, search nearby terrain and entrances rather than assuming the resource is confined to one named site. The available location references do not support a reliable ranking of these alternatives by amount collected.

How to mine the crystals
There is conflicting guidance on the required Cutteray tier: one community reference says Iron Tier or higher, while PC Gamer’s guide says at least Cutteray MK.2. A recently updated item database does not specify a tier, so those labels should not be assumed equivalent or treated as a confirmed requirement for the current build. If your tool cannot mine a deposit, check the in-game item and tooltips and upgrade as indicated.
A buggy or sandbike can make travel and hauling easier, according to the 2025 route guide, but neither is established as a requirement. The community item reference lists Erythrite Crystal at volume 0.4 and stack size 500; those are item-data values, not a reason to bring a particular vehicle.

What Erythrite is used for
Erythrite is refined into Cobalt Paste at a Chemical Refinery. The community item reference lists these recipes, also relayed by a 2026 fan guide:
| Refinery | Recipe for one Cobalt Paste | Time |
|---|---|---|
| Small Chemical Refinery | 3 Erythrite Crystals and 75 mL water | 15 seconds |
| Medium Chemical Refinery | 2 Erythrite Crystals and 75 mL water | 10 seconds |
These are game recipe values recorded by community references, not real-world measurements. Recipe availability or values can change with game updates; check the refinery interface in your build before planning a large collection run.

How current are the location details?
The fan database lists version 1.5.3.6 and an update date of October 6, 2026, and confirms CHOAM extraction facilities in Hagga Rift. It does not confirm a Cutteray tier or the eastern tunnel route. Another fan database notes that its extracted data was not rechecked against version 1.5.3.2. The route recommendation cited above dates to June 2025, so use it as a practical lead, not proof of the current optimal path.
