 thanks chuck,
I don't know the definition of placer deposit, but i'll look it up. 

That is the loose material above your bedrock sorted by gravity. Since the lead is dense, it settles to the boundary zone between the solid and loose materials on the creek bottom. That would make it appear to be part of the bedrock.
