I recently been going to the EAstern Metal Mine dumps in St Fabien. This was a copper/ au sulfide vein to the south and a Nickel/ colbalt/ arsenic/ iron sulphide vein. I found some interesinting minerals. garnierite or anabergite. apple to green green. Their was some mineral I think is a nickel sulphide, dense metalic gray/silvery mineral. I will post some photos
