    Hiking

    The remains of the bases for Californian stamps are among the most prominent remnants at Poldice Mine. These machines crushed ore-bearing rocks into fine sand, contributing to significant noise across the valley. Unlike traditional Cornish stamps, Californian stamps operated more rapidly and thoroughly, with each stamp head capable of crushing 1.5 tons of ore daily compared to the one ton processed by Cornish stamps.
