Minecraft ore distribution: the best Y level for every ore
You need a Stone Pickaxe, a Copper Pickaxe or better; each ore drops 2–5 Raw Copper.

The Stone Pickaxe is a pickaxe, the mining tool for stone, ores and metal blocks. Its material decides which ores drop something when broken. The first real mining upgrade, crafted from any stone material, holds out for 131 uses and can mine iron, copper and lapis ore, but not gold, diamond or redstone ore. It works like every other pickaxe; the Iron Pickaxe page explains mining tiers and enchantments.
It is made with the Crafting Table from 2 × Stick and 3 × Cobblestone or Blackstone or Cobbled Deepslate.
3 × Cobblestone / Blackstone / Cobbled Deepslate + 2 × Stick → Stone Pickaxe
