Arizona has been a leading copper-producer for more than a century. The mining of the metal has contributed to fortune and failure, boom and bust.
The multi-part series Copper at the Crossroads examines the past, present, and future of copper mining in Arizona.
Reporter/Producer Mark Duggan visited several existing open-pit copper mines and sites of proposed future mines. He spoke with citizens who are both opposed to and in support of mining expansion in Arizona.
Listen to the episodes and see a photo gallery below.
Copper at the Crossroads aired in 2011.
