For the past three decades, miners from the Wonderstone Silver Mine near Ottosdal in western Transvaal, South Africa, have been mining various metal balls from deep rock. At least 200 have been found so far. In 1979, some of them were studied in detail by JR McIver, professor of geology at the University of Witwaterstadt in Johannesburg, and professor of geology Andries Bisschoff of Potsshefstroom University.

Metal spheres look like flattened globes that are 1 to 4 inches in diameter, and their surface is usually steel-blue in color with a reddish reflection, and small areas of white fibers are embedded in the metal. These are made of an alloy of nickel and steel, which does not occur in nature and is of such a composition that excludes meteoric origin. Some of them have only a thin shell about a quarter of an inch thick, and when they break, we can see that they are filled with a strange spongy material that has crumbled to dust when in contact with air.

What is most remarkable about all this is that the spheres were extracted from a layer of pyrophyllite rock that dates both geologically and by various radioisotope dating techniques as at least 2,8-3 billion years old.

To propose a secret to a secret, Roelf Marx, curator of the South African Museum in Klerksdorp, found that the ball he had at the exhibition slowly rotates around its own axis while locked in its display case and not exposed to any vibrations from the outside.

Thus, there may be preserved energy in these spheres, which still works after three billion years.
