Coralum Ore is not mined. Despite the name, there is no Coralum node and no Mining suitability attached to it — you pull it off the seabed with a fishing magnet at salvage spots, or you kill Whalaska for 2–3 at 100%.
Salvage spots in deep water, not rocks. Powerful Fishing Magnet at Tech 62 (and it makes 10 per craft). Sunreach expedition pays 30–50. 2 Ore + 5 Coal = 1 Coralum Ingot.
There is no such thing as a Coralum mining level. Version 1.0's "ores that need dedicated equipment" refers to Soralite on Sunreach and Paloxite at the World Tree, which need the Plasma Multicutter. Coralum is a salvage material. Also note that reference entries titled simply Coralum do not exist — the correct pages are Coralum Ore and Coralum Ingot.
Coralum Ore at a glance
| Property | Value |
|---|---|

| Max stack | 9,999 |
| Rarity | Common |
| Mining suitability | None — not a mined resource |
| Obtained by | Fishing magnet salvage, expeditions, Pal drops, chests |
| Internal name | ManganeseOre |
In-game description: "A rare ore formed over countless years in the deep sea. Can be retrieved from the depths with a magnet and fishing rod."
Where to get it
| Source | Quantity | Rate |
|---|---|---|
| Sunreach expedition | 30–50 | 100% |
| World Tree treasure fishing | 12–25 | 100% |
| World Tree fishing spot 02 | 12–25 | 100% |
| World Tree treasure fishpond | 12–21 | 100% |
| Lv60 oil rig, ordinary chest | 15–20 | 54.4% |
| Sunreach Hard expedition | 10–20 | 100% |
| Feybreak treasure fishpond | 8–18 | 100% |
| Lv55 oil rig, ordinary chest | 8–12 | 83.3% |
| Salvage Rank 2 | 6–11 | 100% |
| Salvage Rank 1 | 1–2 | — |
| Feybreak and Sunreach fishing spots, Sakurajima areas, enemy camps | Varies | 2–30% |
The standard Sunreach expedition at 30–50 is the single best source, and it beats the Hard variant, which pays only 10–20. That is unusual — Hard expeditions normally return less bulk and more rarity — but it is what the published tables print, so send Pals on the normal Sunreach run.
Pals that drop it
| Pal | Quantity | Rate | Corroboration |
|---|---|---|---|
| Neptilius | 10 | 100% | Single source |
| Whalaska (Alpha) | 5–10 | 100% | Single source |
| Whalaska Ignis (Alpha) | 5–10 | 100% | Single source |
| Whalaska | 2–3 | 100% | Both sources |
| Whalaska Ignis | 2–3 | 100% | Both sources |
The Alpha Whalaska — "Gentle Ice Lance Whalaska", level 55 — is documented at (-179, 842) in the Land of Absolute Zero. Open on map. Whalaska itself carries Watering Lv5 and Cooling Lv6 and no Mining at all, which is another sign that Coralum is not a mined resource.
The Powerful Fishing Magnet
| Property | Value |
|---|---|
| Technology level | 62 |
| Recipe | 1 Hexolite, 1 Cryogenic Coolant, 1 Bio Battery |
| Work | 4,000 |
| Yield per craft | 10 magnets |
| Deploys at | Salvage Rank 1 and Salvage Rank 2 spots |
In-game description: "A high-powered magnet used in advanced salvage operations. Its strong magnetic pull can retrieve resources and supplies from the ocean floor."
The recipe reads expensive until you notice it produces 10 magnets. Per magnet that is a tenth of a Hexolite, a tenth of a Cryogenic Coolant and a tenth of a Bio Battery — cheap enough to burn freely on Rank 2 salvage spots, which pay 6–11 ore each.
Coralum Ingot
| Property | Value |
|---|---|
| Recipe | 2 Coralum Ore + 5 Coal |
| Technology level | 62 |
| Crafted at | Gigantic Furnace or Ancient Furnace |
| Work | 5,000 |
| Weight | 3 |
| Rank | 4 |
Description: "An alloy made from Coralum Ore found on the ocean floor. Highly resistant to energy, making it ideal for crafting weapons."
Its Coralum Ingot page says 2 Coralum Ore + 5 Coal; its Coralum Ore page says 1 Coralum Ore + 5 Coal. A second reference agrees with the first. Plan for 2 Ore per Ingot.
5 Coal per ingot, against weapons that want 200–400 ingots, means a Charge Rifle can imply 1,000–2,000 Coal. Read the Coal guide and build the Coal Quarry before you commit to a Coralum weapon.
What Coralum builds
Coralum Ingot consumers
| Item | Ingots |
|---|---|
| Charge Rifle variants | 200–400 |
| Energy Shotgun variants | 193–310 |
| Megaboost Gun | 150 |
| Rocket Launcher variants | 75–150 |
| Ancient Furnace | 100 |
| Advanced Workshop | 50 |
| Japanese-Style Hot Spring | 50 |
| Frostallion Saddle | 43 |
| Triple Air Dash Boots | 20 |
| Solmora Saddle | 12 |
Raw Coralum Ore consumers
| Item | Ore | Other materials |
|---|---|---|
| Coralum Ingot | 2 | 5 Coal |
| Intermediate Fishing Rod | 10 | 60 Paldium Fragment, 10 High Quality Pal Oil, 20 Cement, 60 Fiber |
| Beginner Fishing Rod | 3 | 20 Paldium Fragment, 6 Aquatic Pal Fluids, 16 Ingot, 16 Fiber |
There is a neat loop here: Coralum Ore builds the fishing rods that help you get more Coralum Ore. The Beginner Fishing Rod's 3-ore cost is small enough that Whalaska kills cover it before you ever reach a salvage spot.
What to do next
- Queue the standard Sunreach expedition on repeat — 30–50 ore per run beats anything you can do by hand.
- Build the Coal supply first; Coralum Ingots are Coal-limited, not ore-limited.
- Clear the Lv55 oil rig, whose ordinary chests pay 8–12 ore at 83%.
