Placer mining was largely replaced by hydraulic mining and hard rock mining methods. Hydraulic mining used high-pressure water jets to extract minerals, while hard rock mining involved digging tunnels and shafts to access mineral deposits underground. These methods were more efficient and able to extract minerals from deeper beneath the surface.
