Mohave County miner and our mineral wealth., 1921-10-28

NhSf' SAooS III w eiiS piS ehhSo VI Oatman is the United Western. This
 property has been opened to depth of 500 feet and much lateral work has Sbeen carried into adjacent terri tory. Some good ore was picked up in these workings, but the impression prevails that the main vein, which is that of the United Eastern, has been cut, but not explored.
 The operations of the United East ern close to the line of the Western
 has caused new interest to be taken in the property and the management is preparing to do extensive work to
 connect up with the vein as it has
 been lined up by the Red Cloud and
 United Eastern developments. The company is now offering block of
 shares for the purpose of caring for taxes and incidental expenses. In
 1915 Walter Harvey Weed, the in ternationally known geologist, made report on the property, which we will quote from literally in this ar ticle, because MT. Weed at the time was in position to look into conditions surrounding the mine and had access to the nearby properties to an extent that broadened his view of not only the Western but of the whole sur rounding territory. Geologically speaking he said: "The geology of the region (Western) is simple in it's broader features, consisting of an an- cient complex or basement schistose rocks, overlaid and cut by variety of igneous rocks of supposed Tertiary age. The summit of the range near the mine is formed of rudely bedded lavas showing considerable variety of texture, color and composition, the beds dipping gently eastward. Ba- salt, locally called malpais, is the youngest rock and pale, creamy white rhyolites are conspicuous near the summit. Beneath these rocks is a series of andesitic rocks with la tite and other iavas, Below the cliffs forming the west face of the summit, the structure is more complicated, plugs of rhyolite and many dikes be- ing seen. A.a...
 "The predominant rocks in this part of the district is purplish grey, or greenish porphyritic-type of andesite' showing white feldspar phenocrists
 sprinkled through a stony matrix with peppering of darker minerals mostly biotite mica. Though cut by light colored dikes of rhyolite as well as darker intrusions of andesite and other rock types, this andesite being the common rock of the mineralized section of the Oatman and Goldroad camps. ... -v t
 "A prominent feature of the dis trict is the occurrence of many dikes whose wall-like outcrops are traceable uphill and down, often for many miles across country. These dikes are the veins along which most of the mines are located. Some of them are doubt less true dikes, Assured and mineral ized by vein-forming agencies. Ot9- CTS are true Assure veins, along which the mineral solutions have soaked into the wall rocks, altering and silicifying them, so that their harder auartz-rock have weathered out in relief. Almost all the better known mining properties of the dis trict have been located along such veins. Other veins occur, but are less readily found, and until recently since the discovery of rich ore in a vein of this nature in the United Eastern mine, were unfavorably re- garded. In my opinion both types or vein are worthy of exploration.
 "The veins are wide, often averag- ing 25 to 50 feet across, are persis- tent for long distances and through out this part of the district are simi- lar in structure and mineral charac- ter. The vein filling proper is very dense, waxy-looking, yellowish quartz largely a form of feldspar. This quartz is almost always gold-beanng' though only commercially so Tn shoots, especially where It IS curly Ill structure or brecciated by later move ment. Calcite is frequent and of- ten abundant gangue mineral, but in the Goldroad section, does not form a separate type of vein. see no sound reason why the veins should not carry pay ore in one rock as wep as in another. Observation in the Goldroad mine have suggested such limitation, but elsewhere the evidence is against it. In the developed prop. critics, pay ore occurs in well defined shoots often of great length and per sistent to the deepest workings yet reached, namely 1925 feet in the Tom Reed mine. At the United Eastern, the ore shoot cut on the 800 foot level shows 37 feet of ore, on the 50O level, 22 feet of which carries $S6.6o per ton in gold. ... :!
 "The ores are gold-bearing and contain a little silver. Copper is a rarity and no tellurides have yet been recognized. The gold is fne
