Aug 03, 2019 · Copper miners blasted and dug into the earth and delivered 13,000 tons of ore to the crushers six days a week from June 1952 to June 1978. Today, a desert of toxic tailings, heap leach pads, abandoned buildings, machinery and unlined settling pools surround a massive pit lake. The quarry is one mile long, a half mile wide and 810 feet deep

The remaining 10% of copper, around 111kt, went to tailings. If the average copper price in 1999 was US$1,500/tonne then that 10% represented US$166.5 million of metal. Fast forward 20 years and at today’s price, US$5,842/tonne, if that material could be reprocessed and an extra 2.5% of copper recovered (or more), then that’s an additional US$162 million+ of revenue. And that’s before we look at …
