Saturation Diving Ore Types & Mining Yields

This page is the complete ore catalogue for Saturation Diving. Every tier from Common through Legendary is documented here with the drop location, the value-per-chunk, the credit-per-run math by zone, and the upgrade paths each ore tier feeds into. Pair this guide with the mining routes page for the optimal pipe-cluster order in each zone, and with the upgrades page for where each ore tier should be spent.\n\n## How The Ore System Works\n\nFour ore tiers exist in the live build of Saturation Diving. Each tier drops from a specific cluster type, has a credit value per chunk, and feeds into a different branch of the upgrade tree:\n\n| Tier | Value per chunk | Drop source | Feeds into |\n|------|-----------------|-------------|-----------|\n| Common | 8 credits | All zones, shallow pipes | Starter upgrades, low-tier gear repairs |\n| Uncommon | 25 credits | Twilight Reef deep pipes, Mid Ridge salvage | Mid-tier gear, second-tier upgrades |\n| Rare | 75 credits | Mid Ridge bosses, Black Mound salvage | Endgame gear, S-tier suit fragments |\n| Legendary | 200 credits | Abyssal Hollow bosses, Maw Lord first-kill token | Triton Mark VII upgrade, faction unlocks |\n\nThe credit math in this guide assumes the wiki’s reference run: full four-role squad, mid-tier gear, and the optimal pipe-cluster order documented on the mining routes page. Solo runs yield roughly 60% of the credit-per-run numbers listed below because the Salvager slot is empty.\n\n## Common Ore (8 credits per chunk)\n\nCommon ore is the starter tier that every diver mines in the first hour of play. The chunks are small, gray, and have a faint glow when held against a beam of light. Common ore drops from every pipe cluster in every zone, but the drop rate is highest in Twilight Reef’s shallow pipes.\n\n### Where It Drops\n\nCommon ore drops from every pipe cluster in Twilight Reef (drop rate 100%), Mid Ridge shallow pipes (drop rate 80%), and the salvage containers in Abyssal Hollow’s corridors (drop rate 40%, mixed with Rare). For new divers, the highest-yield Common-ore run is a 6-minute Twilight Reef loop with the Standard Tank and the Cordless Hammer-Drill.\n\n### What It Feeds\n\nCommon ore feeds every starter upgrade path: the Twin Reserve tank, the Standard Dive Shell repair kit, the Cordless Hammer-Drill’s pressure seal, and the Pulse Array Mk I sonar battery. Bank the first 200 Common-ore chunks before buying anything else — the Twin Reserve tank pays for itself in 200 chunks and unlocks the first oxygen-quality-of-life upgrade.\n\n### Common Mistakes\n\n- Hoarding Common ore past 500 chunks — credit returns drop because you are passing up the mid-tier upgrades that pay back faster.\n- Skipping Common ore to chase Rare — Rare only drops from bosses, and you cannot reach bosses without mid-tier gear funded by Common ore.\n- Mining the same Twilight Reef pipe twice — clusters respawn every 4 minutes; rotating between three clusters is faster than re-mining one.\n\n## Uncommon Ore (25 credits per chunk)\n\nUncommon ore is the mid-game tier that funds your first S-tier gear purchase. The chunks are medium-sized, blue-tinged, and shimmer under the Salvaged Glowstick’s battery. Uncommon ore drops from Twilight Reef deep pipes and Mid Ridge salvage containers, with a small chance of dropping from Pressure Wraith and Maw Crawler kills.\n\n### Where It Drops\n\nUncommon ore drops from Twilight Reef deep pipes (drop rate 60%), Mid Ridge salvage containers (drop rate 75%), and the Pressure Wraith and Maw Crawler kills (drop rate 30% per kill, max 1 chunk per kill). The optimal Uncommon-ore run is a 12-minute Mid Ridge loop with the Cryo Helix Tank and the Hydraulic Core-Bit.\n\n### What It Feeds\n\nUncommon ore feeds every mid-tier upgrade: the Cryo Helix Tank, the Hydraulic Core-Bit, the Pulse Array Mk III sonar, and the Salvaged Glowstick’s battery upgrade. The recommended savings threshold is 500 Uncommon-ore chunks before buying the first mid-tier gear piece — that covers the Cryo Helix Tank (300 chunks) with leftover for repairs.\n\n### Common Mistakes\n\n- Skipping Uncommon ore salvage in Mid Ridge — most beginners focus on Common ore from pipes and miss the salvage containers that drop Uncommon.\n- Spending Uncommon ore on cosmetic upgrades — the credit math does not work out; cosmetic upgrades have no resale value.\n- Ignoring the Pressure Wraith first-kill drop — that 200-credit ticket feeds into your Black Mound unlock path.\n\n## Rare Ore (75 credits per chunk)\n\nRare ore is the endgame tier that funds your hadal-zone loadout. The chunks are large, purple-tinged, and hum audibly when stacked. Rare ore drops from Mid Ridge bosses, Black Mound salvage, and a small chance of dropping from Abyssal Stalker and Void Siren kills.\n\n### Where It Drops\n\nRare ore drops from Mid Ridge boss kills (drop rate 50%, 1-2 chunks per kill), Black Mound salvage containers (drop rate 80%, 3-5 chunks per container), and the Abyssal Stalker and Void Siren kills (drop rate 40% per kill, 1-3 chunks per kill). The optimal Rare-ore run is a 25-minute Black Mound loop with the Triton Mark VII and Pressure Stability maxed.\n\n### What It Feeds\n\nRare ore feeds every hadal upgrade: the Triton Mark VII suit (worth 1,500 credits), the Pressure Stability perk max (worth 800 credits), and the Pressure Resistance perk (worth 600 credits). The recommended savings threshold is 60 Rare-ore chunks before attempting the first Black Mound run — that covers the Triton Mark VII entry cost with leftover for the first repair charge.\n\n### Common Mistakes\n\n- Burning Rare ore on mid-tier repairs — mid-tier repairs should be funded by Uncommon ore; Rare ore is too valuable to spend on Common-tier gear.\n- Skipping the salvage containers in Black Mound — the salvage containers drop 80% of the Black Mound Rare yield; skipping them halves your credit-per-hour.\n- Solo Black Mound runs — without a full four-role squad, the Hadal Pull aggros on a single diver and burns your Rare ore in repair charges.\n\n## Legendary Ore (200 credits per chunk)\n\nLegendary ore is the apex tier that funds faction unlocks and the Triton Mark VII upgrade token. The chunks are very large, gold-tinged, and pulse with a faint bioluminescent rhythm. Legendary ore drops exclusively from Abyssal Hollow bosses, the Maw Lord first-kill token, and a tiny chance from salvage vaults in Black Mound.\n\n### Where It Drops\n\nLegendary ore drops from Abyssal Hollow boss kills (drop rate 100%, 1-2 chunks per kill), the Maw Lord first-kill token (1 chunk guaranteed), and Black Mound salvage vaults (drop rate 5%, 1 chunk per vault). The optimal Legendary-ore run is a 40-minute Abyssal Hollow clear with a maxed-out four-role squad.\n\n### What It Feeds\n\nLegendary ore feeds the Triton Mark VII upgrade token (worth 2,500 credits), faction unlocks (worth 5,000 credits across all factions), and the Maw Lord trophy wall display (cosmetic, no credit value). The recommended savings threshold is 25 Legendary-ore chunks before attempting the first Abyssal Hollow clear — that covers the upgrade token with leftover for the faction unlock path.\n\n### Common Mistakes\n\n- Solo Abyssal Hollow attempts — the Maw Lord is impossible solo. The wiki has a 100% solo-fail rate over 40 attempts.\n- Skipping the salvage vaults — the salvage vaults are the only consistent Legendary drop outside the boss kills.\n- Spending Legendary ore on repairs — Legendary ore is worth 25x the repair-cost value; never spend it on a repair charge.\n\n## Credit Per Run By Zone\n\nThe credit-per-run math per zone, using a four-role squad and mid-tier gear, breaks down as follows:\n\n| Zone | Run length | Common | Uncommon | Rare | Legendary | Total credits |\n|------|-----------|--------|----------|------|-----------|---------------|\n| Twilight Reef | 8 min | 24 chunks | 4 chunks | 0 | 0 | 292 |\n| Mid Ridge | 18 min | 12 chunks | 18 chunks | 2 chunks | 0 | 942 |\n| Black Mound | 25 min | 0 | 6 chunks | 12 chunks | 1 chunk | 2,750 |\n| Abyssal Hollow | 40 min | 0 | 0 | 8 chunks | 5 chunks | 4,600 |\n\nThese numbers assume the optimal pipe-cluster order documented on the mining routes page. Solo runs and under-equipped squads see roughly 60% and 75% of these numbers respectively.\n\n## Why Tier Specialization Matters\n\nEvery ore tier has a clear credit-per-hour role. Common ore is the early-game bread-and-butter that funds your first 1,200 credits of starter gear. Uncommon ore is the mid-game workhorse that funds your first S-tier purchase. Rare ore is the hadal-game ticket that funds your first hadal loadout. Legendary ore is the endgame capstone that funds faction unlocks. Divers who skip a tier — for example, who rush to Black Mound without first banking 500 Uncommon-ore chunks — typically wipe twice and lose more credits than they save. The wiki tracks the credit math per tier on the tier list so you can plan your spending in order.\n\n## How Ore Drops Change Per Patch\n\nEvery patch reshuffles ore drop rates and chunk values. The wiki tracks every change on the updates tracker and refreshes this guide within 24 hours. Two patterns to watch:\n\n- A hadal tier gets buffed and the value-per-chunk doubles — usually a balance pass that pushes divers toward endgame content; the wiki flags it on the tier list with a footnote.\n- A shallow tier gets nerfed and the drop rate drops below 50% — usually a credit-sink patch to slow early-game progression; the wiki flags it on the updates tracker within an hour.\n\n## Reading The Wiki Recommendations\n\nEvery recommendation in this guide comes with a patch tag. If the wiki says “Black Mound yields 2,750 credits per run” and the patch tag is older than 30 days, check the updates tracker for a more recent number. Credit math is volatile in the first week after a patch and stable for the next 6-8 weeks. Divers who follow the wiki recommendations during the volatile week tend to over-index on whatever the most recent buff was; waiting for the meta to settle usually saves ore.
