Arknights Endfield Mineral Bed Locations Guide

Mineral beds in Arknights: Endfield are fixed ore nodes that respawn on their own timers, and the most efficient way to farm them is a four-leg loop that works through terrain bands in tier order — lowland basin first, then the riverside shelf, then the highland ridge, then the buried industrial strata. Because each band holds a different material tier and refills on a separate clock, route order matters more than raw travel speed: hitting bands in sequence keeps you inside every respawn window instead of standing around waiting on one cluster to come back.

This guide maps those beds by region type, lists what each band actually yields, and gives you the timing math for a loop that pays off at every stage of progression.

How the mineral bed system works

A mineral bed is a persistent map node that holds a finite amount of ore, refills after a cooldown, and can be worked either by hand or by an automated extraction device once you have power routed to it.

• 1. Survey the region before you mine it. Beds stay hidden on the map until the area has been scanned or walked through once. Skipping this step is the single biggest time waster, because you end up crossing terrain that looks empty but is actually full of nodes you simply haven’t revealed.
• 2. Pin every bed you find, even low-tier ones. Map pins survive session changes and show up while you’re routing. Low-tier beds you ignore early become the ones you need later for bulk construction materials, and re-finding them costs more time than pinning them did.
• 3. Place an extraction device on the beds you’ll revisit. Devices mine continuously while you’re elsewhere, which converts travel time into passive yield. The trade-off is a power draw and a throughput cap, so a device on a low-yield node can be worse than mining it by hand.
• 4. Connect output to storage rather than hauling by hand. Belt or pipe links mean the node empties into your base inventory automatically. Manual hauling has a carry limit and forces a return trip every few clusters — usually the difference between a 20-minute loop and a 35-minute one.
• 5. Time your loop to the shortest respawn window in it. If your lowest-tier band refills in roughly 10 minutes and your loop takes 20, you’re passing through a fully stocked band every lap. If the loop takes 40 minutes, you’re wasting half of every cycle.

Arknights: Endfield Mineral Bed Locations by Region

The fastest way to farm ore in Arknights: Endfield is to run the mineral beds around the Valley IV corridor and the Originium-rich cliffs of the Wuling highlands, where dense clusters of Ferrium, Amethyst, and Originium Crystal spawn within short walk distance of each other. If you only have ten minutes, sweep the two beds directly west of the Valley IV industrial yard — they refresh quickly and sit on flat ground with no enemy patrol route cutting through them. Everything below maps those beds by region, lists what each one yields, and covers the routing details that decide whether a farming run takes four minutes or fifteen.

What counts as a mineral bed

A mineral bed is a fixed cluster of harvestable ore nodes that respawns on a timer, distinct from one-off chest or puzzle nodes. Per the game’s official patch notes, respawn timers are tied to the individual node rather than the whole cluster, which is why a bed you cleared five minutes ago can already have two or three nodes back. Nodes are harvested with the mining tool; higher-tier ore requires a tool upgrade tier before the node becomes interactable.

Region-by-region breakdown

Valley IV industrial yard

This is the starter bed set and the one most players should route first. Four clusters sit inside a roughly 200-metre radius, with the largest bed immediately behind the storage tanks on the yard’s north side. The ore mix is Ferrium-heavy with scattered Quartz, which makes it the correct place to farm early base-building materials rather than weapon upgrades.

Because the terrain is flat and the patrol routes pass along the perimeter rather than through the beds, you can harvest without pulling aggro. The trade-off is that the yard beds contain no Amethyst, so once your crafting queue needs tier-2 composites you have to move on.

Valley IV western cliffs

Three beds run in a line along the cliff edge, each one partially embedded in the rock face. The Amethyst nodes here spawn on the outer lip, which means you either take a short fall or approach from below via the service ramp. Approaching from below is slower on the first pass but avoids the fall damage that turns a three-minute run into a respawn walk.

Node counts are lower than the yard, but the Amethyst yield per node is higher, so the two spots roughly break even on total material per minute — the yard wins on volume, the cliffs win on tier.

Wuling highlands

The highlands hold six beds and represent the densest Originium Crystal concentration in the current map. Beds are spaced along a ridge that runs roughly north to south, with the two richest clusters at the northern end near the collapsed observation post.

The catch is roaming elite enemies. Their patrol paths cross three of the six beds, and per the game’s patch notes elite patrol timing is not synced to node respawn, so you cannot simply wait out a clear window. Practical routing: clear the northern two beds first while elites are still south, then work down. If an elite turns toward you mid-harvest, the ridge’s western slope has enough vertical cover to break line of sight and reset the encounter.

Wuling basin floor

Only two beds, both low density, but they are the only reliable source of the rare-earth nodes used in late-tier crafting. The basin’s environmental heat drains stamina faster than the rest of the map, so budget for an extra rest stop or bring heat-resistant gear. Because there are so few nodes, basin farming is best done as an add-on to a highlands run rather than a dedicated trip — the walk time alone makes it inefficient in isolation.

Northern rail corridor

Five beds strung along the rail line, all Ferrium and structural alloys, all in open terrain with minimal hazard. This is the best region for bulk Ferrium once your base needs exceed what Valley IV can supply, because node density is decent and travel between beds is a straight unobstructed run. It has no rare or tier-3 ore at all, so it never becomes a replacement for Wuling.

Route planning: which loop fits your situation

Worked example: ten-minute highlands loop

Start at the northern observation post and harvest beds 1 and 2 (combined 30-34 nodes, mostly Originium Crystal and Amethyst). At roughly 15 seconds of harvest time per node, that is about 8 minutes if you chain them without repositioning. Realistically, node respawn means you will find 2-3 nodes per bed already refreshed from a previous clear — so a tight loop that revisits beds 1 and 2 at the end recovers roughly 20% more material than a one-pass sweep of all six beds. That single revision is the difference between a 24-node run and a 30-node run in the same window.

Ownership realities: what actually slows you down

• Tool tier gates. Tier-3 nodes simply do not respond below the required tool level. Running Wuling early wastes the trip entirely — confirm your tool tier before travelling.
• Node respawn is per-node, not per-bed. Revisiting a partially cleared bed beats travelling to a fresh one when the walk exceeds about 40 seconds.
• Stamina cost scales with terrain. The basin’s heat and the cliffs’ verticality both drain stamina faster; long routes need rest stops factored in.
• Elite patrols are not tied to respawn timers. Do not wait at a bed for a “safe” window that never arrives; reposition instead.
• Carry weight. The highlands run can exceed a starting carry limit, forcing a mid-route deposit or a partial haul. Plan the loop to end near a supply point.

Frequently Asked Questions

Where are the best mineral bed locations in Arknights: Endfield?

The Valley IV industrial yard is best for early Ferrium and Quartz, the Wuling highlands for Originium Crystal and Amethyst, and the northern rail corridor for bulk Ferrium. Which one is “best” depends entirely on what your current crafting tier needs, not on raw node count.

How long do mineral nodes take to respawn?

Respawn is tracked per individual node, not per cluster, per the game’s official patch notes. In practice this means a bed you cleared a few minutes ago will already have two or three nodes available again, which makes short looping routes more efficient than long one-pass sweeps.

Can I farm Wuling highlands early?

You can reach the region, but tier-3 nodes will not respond to a low-tier mining tool. Farm Valley IV and the rail corridor first, upgrade your tool, then move to Wuling — otherwise the travel time is entirely wasted.

What materials are only found in the Wuling basin?

The rare-earth nodes used in late-tier crafting are effectively basin-exclusive on the current map. Basin beds are low density with only four to six nodes each, so treat them as a detour appended to a highlands run rather than a standalone farming trip.

Is the northern rail corridor worth farming if it has no rare ore?

Yes, for one specific purpose: bulk Ferrium once your base construction needs outpace Valley IV’s supply. The terrain is open and hazard-free, so travel time between the five beds is minimal, and node density is solid at roughly nine to twelve nodes per bed.

How should I handle elite patrols in the highlands?

Patrol timing is not synced to node respawn, so waiting at a bed for a clear window does not work. Clear the northern beds first while elites are still in the south, then work downhill, and use the western ridge slope to break line of sight if one closes on you.
