Ores & Materials
Introduction
Ores and materials are the backbone of every crafting recipe in Mine a Planet. This catalog lists every ore, ingot, alloy, and rare drop with the biome where it appears, the rarity tier, and the drill you need to harvest it efficiently. Bookmark this hub whenever you plan a material farming route. Ores spawn in density bands by biome — Earth and Mars have the highest Common density, Europa the highest Uncommon density, Volcano the highest Rare density, and Nebula the highest Mythic density. Smelting always converts ore in fixed ratios regardless of biome, so farming the densest source biome is always the fastest path to your next alloy batch.

Ore Rarity Distribution

|---|---|---|
| Common | Stone, Copper Ore, Coal | Earth, Mars |
| Uncommon | Iron, Silver, Ice Shards | Mars, Europa |
| Rare | Titanium, Magma Ore, Crystal | Volcano, Mars Deep |

Ore Catalog
Stone
Universal starter material — drops on every biome and is the cheapest ingredient for the Common Ingot. Universal starter material — drops on every biome and is the cheapest ingredient for the Common Ingot. Stone is the most abundant ore in the game, so beginners can always queue a full smelt batch without worrying about inventory space. The biome density is highest on Earth, so farm Stone on Earth until you unlock Mars, then switch to Copper as your primary source.
Iron Ore
Mid-game staple — the backbone of the Iron Alloy recipe and the first material that gates drill progression. Mid-game staple — the backbone of the Iron Alloy recipe and the first material that gates drill progression. Iron Ore drops on Mars and Europa outskirts in dense veins, perfect for batch smelts. The recipe unlocks at level 10, and most players smelt at least 10 Iron Alloys before pushing into Europa. Earth has a small Iron drop rate as well, useful for early-game stockpiling.
Titanium Ore
Advanced ore — required for the Titanium Spire, the first drill that unlocks Mars Deep grinding. Advanced ore — required for the Titanium Spire, the first drill that unlocks Mars Deep grinding. Titanium Ore drops on Mars Deep and Volcano in dense veins, and the bulk smelt bonus is worth the batch planning. The recipe unlocks after you smelt 50 Iron Alloys, and most players stockpile 20 Titanium before attempting the Titanium Spire craft.
Mythril Ore
Endgame material — required for the Mythril Destroyer and the Mythril Bar end-alloy recipe. Endgame material — required for the Mythril Destroyer and the Mythril Bar end-alloy recipe. Mythril Ore drops in Nebula and as a rare bonus drop from the Volcano lava boss. The Nebula biome has higher density but requires a Legendary drill to survive more than ten minutes, so clear at least one Nebula run before committing to the Mythril Bar smelt.
Stardust
Mythic catalyst — only drops in Nebula, used as the catalyst ingredient for the highest-tier alloys. Mythic catalyst — only drops in Nebula, used as the catalyst ingredient for the highest-tier alloys. Stardust is the second-rarest material in the game and is required for both the Mythril Bar and the Cosmic Core smelt. The drop density is highest in Nebula but is gated behind the Mythril Bar smelt, so clear at least one Mythril Bar before chasing Stardust.
Core Mechanics
Ores spawn in density bands by biome — Earth and Mars have the highest Common density, Europa the highest Uncommon density, Volcano the highest Rare density, and Nebula the highest Mythic density. Smelting always converts ore in fixed ratios regardless of biome, so farming the densest source biome is always the fastest path to your next alloy batch. Ores spawn in density bands by biome — Earth and Mars have the highest Common density, Europa the highest Uncommon density, Volcano the highest Rare density, and Nebula the highest Mythic density. Smelting always converts ore in fixed ratios regardless of biome, so farming the densest source biome is always the fastest path to your next alloy batch. Rare and Mythic ores reward thorough exploration with hidden veins that respawn on a six-hour timer. Hidden veins do not show on the minimap, so exploration is rewarded over raw drilling speed.
Advantages
Ores have clearly tiered biomes so the grind path is intuitive — you always know which planet to mine for the material you need. Rare and Mythic ores reward thorough exploration with hidden veins that respawn on a six-hour timer. Smelting ratios are fixed and documented, so you can plan a multi-session farming route with predictable output.

Hidden veins do not show on the minimap, so exploration is rewarded over raw drilling speed and the grind stays engaging over long sessions.
Challenges
Higher rarity ores have a low drop density, so a single mining run on Nebula might yield only 3-4 Mythril Ore. Without the bulk smelt bonus, partial batches produce significantly less alloy per ore, so beginners who smelt in small piles waste up to 20% of their grind output. Ore density varies server to server, so farming routes that work in one session may need adjustment the next day.

Quick Tips
Always mine the highest density biome for your target ore — Earth for Common, Mars for Uncommon, Volcano for Rare, Nebula for Mythic. Earth has the highest Common density, Mars the highest Uncommon density, Volcano the highest Rare density, and Nebula the highest Mythic density. Mining the densest source biome for your target ore saves time on every smelt batch. The bulk smelt bonus is worth the wait, so queue full batches of 50 ore from your target biome to maximize the alloy yield per session.
Smelt in batches of 50 ore for the bulk output bonus; partial batches produce less alloy per ore and waste 10% of your grind time. The bulk output bonus is worth an extra 10% alloy yield on top of the base conversion. Partial batches waste the smelter queue timer and produce less alloy per ore, so always wait for a full batch of 50 when you have the inventory space. The bonus applies to every alloy recipe, so it is worth waiting for a full batch whenever possible, especially for high-tier smelts.
Void Shards only drop inside the Void biome — clear a Cosmic Core smelt first to unlock the area before chasing this material. The Void biome is gated behind the Cosmic Core smelt, which requires a Mythril Bar prerequisite plus Stardust drops from Nebula. Clear a Cosmic Core smelt first to unlock the Void biome before chasing Void Shards. The Void biome is the toughest in the game and requires the Cosmic Reaper drill itself plus the Cosmic Wolf pet to farm efficiently.
