Thank you for the link Steve.

I will do a bit of basement chemistry and see what happens.

The best resource is shared knowledge and experience.

Thank you 

Hi all,

I have found a few of the following "slugs" detecting

 They sound like a mineral and don't register high on the Macro Gold Id numbers, but when heated silver metal blobs form on the surface. There is also very small glints of a gold colour. I have not cleaned this 1 yet, only dug it on Sunday.

50 grams

It has a fine grey crystallised structure when broken.

Anybody out there that can offer any information or ideas. I think it might be in the telluride family, but not sure.

Thanks
