The historic Anaconda Copper Mine Site (Site) is an abandoned open pit copper mine and processing facility, located in Lyon County's Mason Valley, in western Nevada. The majority of copper mining, milling and processing at the Site occurred between 1953 and 1978, and secondary milling and processing of ores occurred between 1978 and 2000.

The Pebble deposit is classified as a copper gold-molybdenum porphyry deposit. Pebble has one of the largest metal endowments of any gold-bearing porphyry deposit currently known. Comparison of the current Pebble resource to other major gold-bearing porphyry deposits shows that it ranks at or near the top in terms of both contained copper.

While the current iteration of Pebble was rejected, the Pebble Limited Partnership (PLP) and the threat of large-scale, open-pit mining in Bristol Bay are not going away. As long as there is a need for copper or gold, powerful interests will want to mine those minerals from the Pebble deposit.

1 CuEQ uses metal prices of $1.85/lb for copper, $902/oz for gold and $12.50/lb for molybdenum, and recoveries of 85% for copper 69.6% for gold, and 77.8% for molybdenum in the Pebble West zone and 89.3% for copper, 76.8% for gold, 83.7% for molybdenum in the Pebble East zone. Contained metal is based on recoveries.
