The largest asteroid to have impacted the Earth, 15 km wide, blew away the town of Vredefort, in South Africa, and left there the largest gold residue on the Earth’s surface: half of the world’s gold was extracted there, i.e. half of the world’s gold has been mined here, or 60,000 tons since the end of the 19th century.
ANCIENT DRY PANNING FOR GOLD: In the absence of streams, dry gold panning was used. The young people removed the largest stones; a pile of sandy soil was then placed on an animal skin to remove the heaviest pieces, and the residue was passed to the elders, who sorted it for the gold grains.
Yeast-like pellets, round and ribbed like coriander seeds, that would mold within 24 hours and have a sweet taste.
