As noted under "Series on identifying minerals", this "Your mineral identification questions" is somewhere that people know where to come (such as myself, other geos and those with experience in identification), to find what people want to know - rather than having these questions spread all over different sections of the forum and often unseen. Hopefully once the ball is rolling these might take on a life of their own, since I don't have time to do more than try to start this and look in occassionally - let's see if it works,,,,

thumbsup Pic 1 looks like a solid form of Pyrite... But I don't think Pyrite is Magnetic.... Have you tried a streak test?..
Try some of these...

Thanks LW,
I took your advice but kinda hard to get correct temp when it’s 45c out here but surprisingly I took a few from my pile and they where still pretty cool to the touch on my lips even felt smidge icey in this stincker of a day lol 1517111939_7cbf5fad-a58f-47ef-880c-94f852bb0d84.jpg

1517113648_interesting.jpg

Found this whilst prospecting for gold. The GPZ liked it, and so did the makro obviously (it likes a lot).
It weighed over 5 kilos and I brought it back and broke it down. I haven't crushed it yet, but will do one piece tonight.
What got me interested is besides the silvery minerals visible, is that the pinpointers both go off on it.

Has anyone come across anything similar looking?

Looks to be pyrite crystals in there too hayyou. Will be interested to see what Goldirocks thinks and see what's in it after crushing, such as native metals?

I'm thinking maybe some sort of silver ore but hey what would I know.... smile

Might have to wait for some cooler temps Shaza... roll if ever that happens...

Very interesting hayyou... Keen to know your crush results... 8) Tin or Silver is my guess too... and a vein of Pyrite?

Just crushed some and panned it out. Could only see heavy pyrites.

So maybe its just highly mineralised and sets the pin pointers off. Not sure.

I will test it out with Minelabs latest pin pointer and see if it grunts or not. That will be interesting.

I haven't had experience panning silver or tin..lol. I know that whatever it is, it is not malleable. It crushed with pressure.

This is at 50x

I can still see quartz through that piece at 500x. lol

Looks like it. The sharp edges seem to tell me its just pyrite. But pyrite has a lot of friends that like to hang out, I couldn't see anything.
Maybe someone else can see something.

Was it found in a Tin or Silver Area?..... Might have to do a SG test or even a Streak Test might help...

It was in an area that produces gold. The area is associated with other minerals as well, so yeah.

Some more hints might help like......Is it heavy or light?. Lots lying around or is it the only piece there.. location of your find may help too... Don't need exact place but area would help.. and a close-up to see the 'structure' of the minerals. hmm thumbsup

Magnetite?, Galena? it could be... need more info to be more accurate.... smile

It does look like it has parallel cleavage surfaces (very rare in quartz). But what is its hardness? Topaz is 8 on Moh's scale sp will scratch quartz - quartz cannot scratch topaz
