[QUOTE="BigWave, post: 414523, member: 6786"] Another interesting fact about pyrites is that it's a semi-conductor, so will give a reasonably low reading on an ohm-meter - not a very low reading like gold or silver (< a few ohms), but generally in the range of 100ohm to a few kohms. I used to use these sorts of minerals as a kid to make the "cats whisker diodes" in crystal sets (if you're too young to know what they are - use google). If it's a low conductor, then reasonably certain that it's a form of pyrites. [/QUOTE]
