QUESTION:How can a geologist help mines?

ANSWER:Geologist prospects study the rock on the surface and study maps of rock beneath the surface. Geologists can map the size and shape of an ore deposit by making careful measurements of Earth’s magnetic field over the deposit. This works really well for magnetic elements such as iron and nickel.
