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.
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.
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.
