Thats a pretty intense chemical composition! Were you able to determine any other elements in there such as sulfur or phosphorous (i.e. to determine the mineral class)? Also what rock type was the surrounding environment?

I found these buried underground in a sealed metal box when I was preparing newly acquired virgin stand. I took them to School of Mines for testing and they came up with the chemical composition I have indicated. But they failed to identify what mineral those were. They suspected that they could be steel nuggets but when they put them into acid they could not dissolve, instead the rust cleared showing silver grey metal. These appear to have been buried by somebody in a sealed small metal box for many years judging by the state of the metal box which is quite heavy. These nuggets are quite heavy and the smallest weighs one gram.
