When flowing lava (non-source) contacts water source blocks, the resulting cobblestone is replaced with random ores (e.g., diamond, iron, gold, coal).
By default, there is a 10% chance to generate ores. A command can force 100% ore generation.
Supported Ores
Diamond Ore, Iron Ore, Gold Ore, Coal Ore, Redstone Ore, Lapis Ore, Copper Ore.Emerald Ore
Command Control
Use the command /brushmining toggle (requires OP level 2) to switch modes:
Force Ore Mode: Always generates ores when conditions are met.
Probability Mode (default): 10% chance to generate ores.
Note: Starting from version 1.1.0, there is a probability of generating ore (including water bearing blocks) as long as there is contact between water and magma.
