The ancient gold mines and placer rivers of the archaic kingdom of Cofachiqui, in the southern Appalachian Mountains of America discovered by Hernando De Soto for the crown of Spain were known and exploited by the local tribes who made axe heads of a mixture of copper and gold, the ancient Etowah buriel mound there having housed a copper plate with ancient mexican-engraving motifs thereupon, indicating that the mound builders and miners of the southern Appalacians had come from the south, from the ancient Yucatan culture of the Olmecs, whose mining expeditions sailed north to the rich mining district where the borders of the states of South Carolina, Georgia, and Tennessee meet; the progeny of the Yuchi tribe, which diverged into Shawnee, Delaware, Chickasaw, Cherokee, and Creek nations, the tribes who led De Soto to the gold rich areas, which were then expoited by the Spaniards for decades.
This information is from W. J. Perry’s classic work, The Children of the Sun, documenting that global seafarers were navigating circa 2000 B.C. in search of gold, silver, pearls, copper, tin, and rare spices, as well as, sandalwood, which grows only on the Malay Peninsula, obtained by King Solomon of Israel circa 950 B.C. when his phoenician fleet sailed to Ophir, named after a son of Joktan, who was a son of Heber (the namesake of Iberia); the Mount Ophir known today as Gunong Ledang, which is east of Malacca, with vast and very ancient underground mine shafts confirming that this was a prime source of gold in the ancient world.
It’s becoming obvious to even the most entrenched skeptics of ancient transoceanic diffusionism that the ancients circa 2000 B.C. were engaged in global navigation in the pursuit of valuable minerals and rare spices; they had the means to precisely navigate by the wobble rate of the earth’s axis, 72 years/degree (simply explained in article #2 at http://IceAgeCivilizations.com), so why not? The pursuit of gold has always been a big motivator, and the ancients were no different, sailing in wooden or reed-bundle ships by the navigational method in the link, so they had the means and the motivation to have sailed to and explored much of the world, actually during the Ice Age, revealed with the ancient source maps exposed by Charles Hapgood in his classic, Maps of the Ancient Sea Kings.
