While heap leaching for copper was under discussion in the 1920s, he said, leaching of residual material in old stopes began in 1923 at Bisbee, Arizona, USA. This was followed by the in situ leaching of ore left over from block caving at several mines, including Ray and Miami; in the late 1950s, Miami created a block cave stope specifically for low grade ore leaching.
