 Along the course of these great out crops parallel to the main range Qocal- ly referred to as dykes) occur filled Assures of brecciated country rock, usually andesite, porphyry and in some instances an intermixture of rhyolite breccia. These materials are bonded by calcite tor calcspar) as depth is gained in sinking on the veins. The mesa becomes more or less silicified and more or less impregnated with gold. Apparently intense silicification means greater values in gold.
 While more or less commercial ore in the form of quartz is found at or near the surface, the big mines of the dis trict so far have found their main de- posits and values from 200 to 1000 feet.
 Therefore it seems to be a question of deep mining to produce bonanza re- suits. If we accept the Tom Reed, United Eastern, and the Gold Roads in general make up and characteristics as reasonable evidence for the future pos abilities of ore occurance in like forma- tions. There is much to expect from very large area afore mentioned.
 Having investigated the Red Gap, Union Pass and Secret Pass sections and many localities intermediate. 1 have been greatly interested at their close relationship and fail to under stand why any of the localities or any of the river range country from the Red Gap to the Black Range will not prove just as valuable as the country in and around Oatman.
 Due to systematic development and much greater depth gained, the mines in and about Oatman make a much better showing than the two to three hundred feet shaft work in other To- calities. I feel safe in making the pre- diction that an equal amount of de- velopment work either at Red Gap, Union Pass or Secret Pass would prove these localities equally as rich in precious metals as any locality within the boundaries referred to.
 As matters stand just at this time. The mining world is confident of a large area of country around Oatman and their confidence expands as the area enlarges and it is not too much to say that their confidence is we'll placed. 1 might also suggest without a refec- tion on this immediate locality, that some of the other localities would look just as good to many of the local en- thusiast if they knew more about them.
 Very naturally Oatman and vicinity on account of the Tom Reed and the United Eastern are more attractive to the prospector, miner and investor. At the same time the area of mining possibilities is increasing every day. New people calling in making locations reach little farther out until at this time the four and five mile circle looks good even to the old timer, many of whom sat around and waited for the tenderfoot to wake him up.
 Every day brings news of valuable finds beyond the boundaries, originally considered valuable and so it goes and we may not be surprised to hear of startling disclosures of the precious metals in any quarter of the "River Range"
 The impression seems to have gone out that the conditions producing gold in this country are widely different from all and any of the well known gold producing centers. 1 fail to see where in there is much if any difference. The veins are well defined Assures and most likely of great depth, magnified in this respect by the character of the eruptives that surely are not of super ficial origin, consequently if the erup- tives originated at great depth it would naturally follow, that the circulating medium that deposited the gold did not confine itself to upper and shallow channels. In support of this view the deepest workings in the camp show oxidized materials at the $50 to 1000 foot level.
 Another feature worthy of note and bearing out the claim of deep minerali-
