[Dave Myers]

Hi List,

Wondering if there are any geologist on Here who have seen porphyritic type rocks, that they have seen, that are full of silver-grey metal.

I would like you to look at pictures of the rock I found, That contains

These 1mm size, silver-grey type nuggets, in the matrex, of this rock!

Thanke for any Help.
