Gold Mining in Oklahoma

     
    The gold mining Activity in Oklahoma is related to the gold found in the Indian area. Basically, gold in small quantities was found in the Wichite Mountains located in that part of the Indian Territory which was later known as Oklahoma. Mining excitements were from time to time brought by people of these localities. Rumors of the existence of rich gold and silver mines, especially in the Wichita Mountains have circulated for many years and have been largely responsible for much prospecting in the place.
    It is important to mention that legends of Spanish mines and miners are connected with this locality as with many others of the Mississippi Valley, and are largely responsible for the constantly recurring periods of excitement which came to those residents in the region, the subsidence of which left disappointed and embarrassed individuals. Owing to considerable friction growing out of the filling of mineral claims on settlers land, the United States Geological Survey undertook in 1903, to ascertain the truth regarding the occurrences of gold in these hills. The results of these assays on samples taken showed no trace of gold, and later samples of ore, collected by those interested in the so-called Beam process of gold extraction, were taken to Washington and assayed with similar results. It was evident that if gold exist in the rocks of the Wichita Mountains, it is in such small quantities.
    The region in which gold was reported includes the Wichita Mountains, located within Coddo, Comanche, Kiowa and Greer counties of Oklahoma. This area was known as the Kiowa-Comanche Reservation, which was opened for settlement in 1901. The core of the mountains consists of crystalline rocks including granite, gabbro, porphyry and greenstone dikes, partially surrounded by Paleozoic limestone. The gabbro and porphyry are pre-Cambrian. There are five modes of occurrence that were prospected: well-defines quartz veins cutting gabbro and granite, greenstone dikes cutting all crystalline rocks indiscriminately, contacts of granite and gabbro, disintegration products of gabbro and occasional simple shear zones.
