But I failed to find that claim to be supported anywhere in the literature. Even 500m is much too shallow of a depth for manganese nodule formation. I found several references which reported these nodules having been found at depths of 5000 feet. Would it be possible to find that newspaper article that you made reference to? Because if it were truly possible to recover those nodules from that shallow of a depth, it would make the "mining" of that form of ore much more economically possible. What I did find were more reports which confirmed that these nodule are very POROUS, which convinces me that the item up for auction is NOT a ferromanganese nodule, regardless of questions about depth of formation. The density of this item is more suggestive of something much more commonly found on eBay: "sulfide slag" !! What I hope results from all this OT discussion, is that the "winning" bidder for this item gets it properly identified and the results are finally published here on the List. Bob V.
