Can somebody help me identify this?

Almost looked past it as a hot rock, but the detector insisted it was metallic, break the crust off with a hammer lo and behold, it is in fact a metal, obviously quite brittle, and I don't think it's lead/aluminium/silver bevause, well for one it's brittle, and it's damn hard, I can barely scratch it with a knife.

It seems heavier than rocks it's size, but it's hard to tell just how heavy it is without scales.

Am I looking at platnium/palladium here? Or am I getting prematurely excited?

Cheers!

platinum is very soft mate.. About 4-4.5..

Dosnt look like platinum.
From the pic it just looks like a bit of aluminum slab.

Steel is only 4-4.5 though, so a hardened knife would be slightly harder.

Aluminium is usually more ductile, also it isn't hard.

Rhodium maybe?

An SG test will reveal a lot

Could it be silver?

Could it be silver?

Maybe, but silver oxidises dark and quite quickly, plus it isn't too hard.

A guy out bush reckons it's lead for sure, I haven't seen hard brittle lead before, but I'll hit it with a propane torch and see what happens tomorrow arvo, we will see what happens :Y:

Might buy some cheap dealer scales and try an SG test.

Perhaps post this in the "Your mineral identification questions" thread. People like Goldierocks check there and might have the answer for you.
