Roger Clark posted a comment to Madan's letter explaining how he calculated the 100 mines:
"On July 21, 2009, Arizona State Director of the Department of Mines Mandan Singh testified before Congress that "...there will be approximately six(6) mines in operation at any one time and another six (6) being reclaimed over roughly a 20 year period." http://resourcescommittee.h...
Six mines per year for 20 years equals more than 100 uranium mines of 20 acres in size or larger within watersheds that drain directly into the Grand Canyon. I stand by my statement in the Republic's story.
