Here's a few micro pis's of Pyrrhotite from my H&D claim most likely mixed with pyrite& chalco.Its weight is heavy massive sulphide ,I have yet to assay this.It will be interesting to see if its carrying Pentlandite and possible trace Au/Ag,Coppers a given. <_miner_>                                                                                                                                                                       
Here's a couple of pic's below of some with garnetite present.


Pic's below with with chalcopyrite mixed in the pyrrhotite.

Cool colors - almost looks like Peacock ore (Bornite)!

Did someone say

Hi MentalCoinCoin.

Here is a suggestion for a test you can perform yourself on your grab samples for detecting Nickel. You can use dimethylglyoxime on it, and if the solution turns pink, well you have Nickel ore. You can find this product at a pharmacy for nickel allergies, or go on Google under spot test for Nickel. Old timers used this easy method for discovering Nickel. The price of the testing product varies greatly.
By the way, your samples seems to be rich in sulfides. <-good_>

Good luck.

Naej

ya I would bet by the looks ebuyc,there's most likely bornite mixed in the copper parts alright.
 
And Thank you Naej for the info on testing for nickel,every bit helps.



Its the heaviest rock by volume I have ever found.
Sending some away for assays,with other rock in about a month.

I'm happy to know it might help you.

By the way, what is your host rock?
Is the mineralization in a magnetic element?
