After doing some book research
 I came upon "Purpurite," based on the description provided, IE occurs as crusts, compact, granular masses, brittle, slightly powdery consistency - it 99.8% matches what I have. Why did I leave off .2%? - Because, I don't have any means, currently, to do a scratch test. Book says it will leave a dark red streak. A ceramic tile would work for a scratch test, right? Just to remind ya's what the deuce I'm talking about, provided some pics, again. (The first pic looks different then the rest, because it's sprayed with clear coat as not to crumble.. more so than it had)

Hmmm. Streak test is what I think you meant. Scratch test can work as well, but for hardness. With that said, the fist pic I was gonna say bornite. The next two shot that down, and I'm thinking lapis. But also don't know the site or the geology.
