We have a large rock that was buried in our back yard. We have having some grading done so we have started to chip away at the rock. We have found a lot of quartz. In some of it we are finding "silver" pieces the size of a flea. The pieces are usually found near a empty pocket in the rock. We are also find pockets of yellow fluffy stuff. Limonite I assume?
I can post some pics if anyone is interested.
