Dear Editor,
Interesting history of local mining (EagleHerald, page A7, Nov. 4). Many things have made today’s mining much worse than yesteryear’s. In the gold rush days, mining was like picking the chocolate chips out of the cookie. Notice the pickaxe and shovel on the WI flag. Today’s mining is mining the sugar out of the cookie. About 98% of today’s mine product is waste rock. The local proposed metallic sulfide mine’s waste rock reacting with air and water, becomes sulfuric acid.
