Morphology

mineral + vein

The phrase is a straightforward noun phrase combining 'mineral' (a naturally formed inorganic substance) with 'vein' (a narrow seam or deposit), so the meaning is directly compositional. This construction is cross-linguistically common and follows standard English noun + noun semantics, so a B1 learner who knows both constituents will readily infer 'a seam or deposit of mineral ore'.

Etymology

Mineral vein comes from the image of a thin line of minerals running through rock, like a blood vein in the body, because miners could see a clear streak of metal in the stone. So today mineral vein means 'a layer of valuable minerals' that miners can follow and dig out.
