Breaking bedrock, and concreted gravels using a demolition hammer or jack hammer. Worked very well on the bedrock which is a decomposed rock to start with. I will be testing each bedrock area separately to test for gold values. Also took some of the placer materials to demonstrate the running of a trammel to my Mi9ning class back at school.
