Manganese Nodule - Very Large
Manganese nodules are scattered about in the millions, packed with important metals -- manganese, iron, and even the platinum group of elements. The difficulty is that they are lying at the ocean bottom -- and it's hard to mine efficiently under 3000 meters of water.
Here's your chance to have a rare manganese nodule sample from the depths of 3000 meters on the Pacific Ocean floor, for a very inexpensive price.
