Ore
From Project Rebearth
Ore is a resource in Project Rebearth extracted from Iron Mines and refined at the Refinery into 
Metal. The Stone Biome has the highest 
Ore yield. Ore is the first step in the metal production chain, which ultimately produces 
Tools, one of the most critical resources in the game.
Production
| Building | Wood | Stone | Earth | Arctic | Workers | Notes |
|---|---|---|---|---|---|---|
| Iron Mine | +40 | +100 | +60 | — | 50 | Consumes Tools (-1/day); upgrades to Improved Iron Mine
|
| Improved Iron Mine | +80 | +200 | +120 | — | 100 | Upgraded Iron Mine; consumes Tools (-1/day)
|
The Iron Mine is the only source of Ore and has the highest output in the Stone Biome (+100/day), followed by the Earth Biome (+60/day) and Wood Biome (+40/day). The Improved Iron Mine doubles output in all biomes but requires 100 workers compared to 50 for the standard version. The upgrade costs 100 
Scrap. Iron Mines must be placed at least 1,500 meters apart from each other and are not available in the Arctic Biome.
Production Chains
Metal Chain
The Iron Mine produces Ore, which the Refinery converts into Metal at a rate of 50 Ore/day to +10 Metal/day (20 workers, -0.2 Tools/day). The Tools Workshop then consumes 4 Metal/day and 5 
Wood/day to produce 2 Tools/day (10 workers). This chain is essential for sustaining Tools supply, which is required by many advanced production buildings.
Consumption
| Building | Ore Rate |
Output | Tools Cost |
Workers | Notes |
|---|---|---|---|---|---|
| Refinery | -50/day | +10 Metal/day |
-0.2/day | 20 | Converts Ore to Metal
|
The Refinery is the only building that consumes Ore. It converts 50 Ore/day into 10 Metal/day, also requiring 0.2 Tools/day.
Storage
| Building | Volume |
|---|---|
| Center | 5,000 (shared with all resources) |
| Square | 10,000 (shared with all resources) |
| Warehouse | 5,000 (shared with all resources) |
| Iron Mine | 500 ( Ore only)
|
| Improved Iron Mine | 1,000 ( Ore only)

Other Sources
Affected By
| Effect | Source | Multiplier | Type |
|---|---|---|---|
| All production | New Town Boost | ×2 | Automatic (4 days) |
| Great Federation | ×1.1 | Alliance type | |
| Science League | ×0.8 | Alliance type |
Unlike Wood, 
Stone, and 
Earth, Ore production is not affected by the goods production modifier. Only the all production effect applies, which affects every production building in the settlement.
