(Taken from the Minerals Identification Flowchart on soinc)
1. Galena
2. Goethite
3. Olivine
4. Malachite
All right (number 2 is actually hematite, but given the description in the flowchart your response applies).

Your turn.

For future reference, goethite is not silver and is also not metallic (also kind of magnetic? I remember seeing a goethite/limonite specimen that was just barely magnetic). Sorry, I just wanted to kind of clear that up.

I was looking for what the diagram is called, which is a ternary diagram, but otherwise correct!
