The panner australia 0 Posted September 19, 2020 Share Posted September 19, 2020 Detected this rock first thought it was blue metal but non magnetic outer surface of rock small blow holes rock extremely hard maybe sediment rock or mud rock when cracked open there appears to be a fine metallic mineral yellow colour thru out the rock but not on the surface Did pan off after small sample crush. I got about 10kgs all about egg size or slightly larger all sing over the detector. Any help or advice would be appreciated Quote Link to post Share on other sites
