What Am I? The Answer is......

My what am I is a rock from down under..Yes 1200 feet under ground. It is called Pirite with calcite. Southeast Missouri is scattered with Iron Ore Mines, they are called the Buick Mine, Brushy Mine, #29 Mine, Fletcher Mine, Casteel Mine, and Sweetwater Mine. My husband and aproximately 50 others work at the Sweetwater Mine. They work daily getting over 3000 tons per day of copper, zinc, and lead. He has been at this job for 23 years..Mining is the best paying job for us trying to live in an rural area..These kind of rocks are for being collected..Anyone that would like a piece of one, let me know I would be glad to send it to ya...always Judy
