Dig back further. There are glacial sinkholes of 400 to 800 ft deep, or even 300M (1,000 ft), in the karsk around the glacial edge - including the Nova Scotia area. 200 ft deep is just a walk in the ice-age park.

Thanks for the clarification on the sink holes in regards to the clay. But that doesn't explain the stratified rocks, and it certainly can't explain the brass. Maybe past searchers were stupid enough to plant brass instead of gold on their drill bits? I doubt that in the extreme.
