White Pine Copper Mine, Copper Shavings, 9 Pound Lot

Description

A 9 pound lot of copper shavings from the former White Pine copper mine at White Pine, Michigan; possibly from milling down a wire ingot
.
Shown next to a nickel for size comparison; some have light corrosion.
Ingots were being poured up until 1982, when the mine began producing pure copper by the electrolytic process.
See my book for pictures and information,
White Pine Copper: An Illustrated History of the Mine and Its Ingots.
This book is available from my ebay store.
The White Pine mine produced over 4 billion pounds of copper and 45 million ounces of silver from 1955 to 1995.
