Ore progression

Minecraft tools follow a strict tier system. You must mine each tier with the previous tier's pickaxe (or better). Using the wrong tier will break the block but drop nothing.

Where ores generate

With the 1.18 Caves & Cliffs update, ores now follow triangular distributions with a sweet-spot Y level. Below Y = 0 the world is made of deepslate, where ore variants are slightly tougher to mine.

Mining techniques

Branch Mining

At Y = βˆ’59, dig a main tunnel 2 blocks tall. Branch off every 3 blocks to maximize ore exposure while minimizing mining.

Best for: Diamonds, Redstone

TNT Mining

Use TNT to clear large areas quickly. Works best in the Nether for ancient debris since it's blast-resistant.

Best for: Ancient Debris
πŸ›οΈ

Bed Mining (Nether)

Beds explode in the Nether. Cheap alternative to TNT for finding ancient debris.

Best for: Ancient Debris (budget)

Cave Exploration

Explore naturally generated caves. Less efficient but more fun. Watch for mobs and lava.

Best for: Variety, early game

Enchantments for mining

Efficiency V

Massively increases mining speed. Essential for large-scale mining.

Fortune III

Multiplies ore drops. Average 2.2x diamonds. Does not work on iron/gold/copper.

🧱

Silk Touch

Drops the ore block itself. Store for later Fortune mining. Required for glass, ice.

πŸ”§

Unbreaking III

Tool lasts ~4x longer. Essential for expensive netherite tools.

Pro tip: Fortune vs Silk Touch

Use Silk Touch to collect ore blocks, store them, then mine with Fortune III later. This maximizes returns and lets you use a single Fortune pick for all ores.
