There are two types of ore generation: Small Ores and Mix Veins. Small Ores generate as semi-common single blocks. They are intended as a way to get started and acquire initial tools, but are not intended to be used as primary sources of metal for machinery. When broken, they drop either a Crushed Ore, an Impure Pile of Ore Dust, or, if applicable, a Gem. Additionally, they may drop a Dust or a Dirty Dust of the Stone they were found in. (This can be Stone, Netherrack, Red/Black Granite, or End Stone.) Small Ores cannot be picked up with a Silktouch Pickaxe, however a Fortune Pickaxe will slightly increase their yields. Importantly, Small Ores can be mined at 1 mining level lower than the ores they contain, allowing a miner with a Stone-level pickaxe to obtain enough Iron to craft an Iron Pickaxe. (GregTech Iron Ore(s) cannot be mined with a Stone pickaxe, you need Iron or Bronze to mine them.)
