Amethyst Ore is a basic ore resource in Arknights: Endfield that you extract from Amethyst Mineral Beds and process at your AIC.
Quick answer: Amethyst Ore is found only in Valley IV, with 12 mining spots across The Hub (6), Valley Pass (2), and Aburrey Quarry (4).
Amethyst Ore locations (Valley IV)
All Amethyst Ore mineral beds currently sit inside Valley IV, spread across three named areas. If you’re trying to confirm you’ve found everything, the key number is 12 total mining spots.
| Region | Area | Amethyst Ore mining spots | What “close enough” looks like |
|---|---|---|---|
| Valley IV | The Hub | 6 | Clustered together on a short elevated patch west of the initial Core AIC Area. |
| Valley IV | Valley Pass | 2 | Northeast of Valley Transfer, overlooking the Abandoned Trail. |
| Valley IV | Aburrey Quarry | 4 | Two near Stockpile Refuge; two on the lower levels of Stockpile Area, adjacent to each other. |
Amethyst Ore in Wuling
There are no Amethyst Ore mineral beds in Wuling. If you need Amethyst Ore while operating in Wuling, it has to be moved in via Regional Transfer.
How to mine Amethyst Ore
Amethyst Ore can be mined manually at a mineral bed, or automated using an Electric Mining Rig.
Step 1: Find an Amethyst Mineral Bed in Valley IV (The Hub, Valley Pass, or Aburrey Quarry) and approach the nodes in the bed.
Step 2: If you want automation, place an Electric Mining Rig directly on an Amethyst Mineral Bed node.
Step 3: Ensure the rig has power by placing it within range of an Electric Pylon. If it’s unpowered, it won’t run.
Step 4: Confirm mining is working by checking that the extracted Amethyst Ore is being sent to your Depot for AIC use.
Aburrey Quarry “Refuse Stockpile” Amethyst bed access (when it seems blocked)
One Aburrey Quarry Amethyst node group is underground at Refuse Stockpile. If you can see the location but can’t reach it, access can be gated by a door that requires repairing its switch.
Step 1: Get to the door area (players commonly prepare Electric Pylons and a Relay Tower for power routing in that section).
Step 2: If the door switch repair is missing a part, progress until you can open the Originium Science Park area and complete the exploration mission Dusty Old Files to obtain the missing repair piece.
Step 3: Repair the switch, open the door, and head underground to reach the Refuse Stockpile mineral bed.
How you know it worked: the door opens and you can physically stand next to the Amethyst Mineral Bed nodes to place an Electric Mining Rig.
What Amethyst Ore is used for (and what to expect later)
Amethyst Ore is described as a purple crystalline ore that can be processed with the AIC and used in precision manufacturing, including electronics. In practice, demand tends to be front-loaded: once you’re past early progression, many factories shift to relying on Originium and Ferrium, with Amethyst appearing less often in ongoing production chains.
