Morphology
The meaning is directly compositional: a mill that uses stamps to crush ore, so a learner who knows 'stamp' (a crushing/pounding device) and 'mill' (a processing facility) can infer the overall sense. This follows common noun–noun compounding patterns and is therefore immediately comprehensible to a B1 learner.
Etymology
Stamp mill comes from the machine's action: heavy iron stamps drop again and again inside a mill to crush rock and free the metal. That's why it means 'a machine that crushes ore'.
