I believe the dredge started to suck up a few chunks of metal buried beneath the sands.... clogging up a few of the workings of the beast.... Ironically , I was talking to Gerry Kuhn last week about all the "lost" dumps scattered beneath the sands in the old Gemsbok area.... don't think SAMETALS got all everything....
Michael there was a big scrap dump South of the Boiler shop and an even bigger one North but I suppose if they got someone to clean out these places it would be hard to believe they missed these areas.
Far as I know, they've been sucking up weird stuff 2 years back. And it was not diamonds.. New-year3
