The US EPA will be taking public comments at a meeting in Dragoon, AZ from 7:00 pm to 9:00 pm, on February 27, 2018.

The meeting will be held at the Dragoon Women’s Club, 1871 North Johnson Road, Dragoon, Arizona.

Excelsior Mining is planning an in-situ copper mine on private land near the town of Dragoon and Texas Canyon (between the towns of Benson and Willcox upstream from the Willcox Playa).  Excelsior Mining was formed in 2005 and this is their only mine project.

In-situ mining is a type of mining that injects sulfuric acid into the ground to dissolve copper and other minerals.  This toxic solution of copper and acid is then pumped from the ground and processed to remove the copper.  In-situ mining, by definition, is the intentional pollution of ground water.  In-situ mining has long been used to produce uranium and at several existing copper mines but has never been attempted to mine copper in a greenfields location.  No in-situ mine has ever returned the groundwater to pre-mining conditions.

The US Environmental Protection Agency (EPA) is currently taking comments on a draft Underground Injection Control permit that would allow the company to drill 1,400 wells and inject over 7,000,000 gallons of sulfuric acid a day into the groundwater. 

What could possibly go wrong?!!

Please see our sample comments letter to EPA to use for talking points to use if you speak at the public meeting.

If you cannot attend the public meeting, please send the EPA comments.
