IRRIGATION SCHEME NORTH OF NEEDLES
Colonization on Colorado River By Los Angeles Promoters
 - Options by BisbeeiteS

 Plans are under way for large ir- rigation and colonization project on the Colorado river. in northwestern Mohave county. Arizona. northeast of Needles. The promoters are Lucian Eaves and D. NJ Martin, operating as the Eayes Engineering company or los Angeles. They have organized the Rio Colorado Land and irr1sa..o'i company and have taken over con tracts held by Mir. Martin with the Santa Fe for 20.00o acres of railroad land This will be subdiyided and disposed of to settlers. besides putting in an irrigation system to furnish wa ter to So.000 acres of government land around old Fort Mohaye, soon to bc thrown open to the public.
 The plan is for an enterprise alonS much the same lines as that in ln- perial valley. For some time there has been a dispute between the gov ernment and the railroad over lands which have been settled. The allot ment tothe Mohave Indians of forty acres per family has been made, and 50.000 acres will be thrown open to American citizens for settlement with in six months, it is expected. This section will be under the Bulls Head dam. planned by the government, and known as the Needles project
 Eaves and Martin have an option | on the old Mohaye Milltown railroad. ! narrow gauge route from Mellen, on | the Santa Fe. into the San Francisco mining district, that has long been q ! joke to railroaders and miners. It will | be torn up and relaid with new steel and ties as a standard gauge to the principal mines including the Pioneer with branch up the Colorado river to Fort Aohave. to tap the agricultur- al lands. The benefit to miners of this railroad building will be very l great. and it will be followed by ex- tensive development

 The Uitimatum shaft is down about | eighty feet and will encounter the lime and iron in the neighborhood oi l 50 feet The intersection of the
 Black Bonanza ledge and the lime. | stone reefs of the Ultimatum is
 marked by two immense outcrops oi | iron and it is the lower one Of these that the shaft Is being sunk to de yelop, as well as the Black Bonanza ledge. The Alvin controls coco feet
 lengthwise of the limestone reefs an. about 2000 feet of the Black Bonanza ledge which crosses its group and ha future full of bright possibilities. Joining the Ultimatum group on ths south is the Black Bonanza group covering 4500 feet in length of th' Black Bonanza and Greenhorn ledges owned by local people, who expect [,
 start development on small scalr within a short time. To the east ol
 the Ultimatum are the SwartZ X Neyins. Neyins Genung. Spencer anC Whitehouse & Snapp groups, all o
 which are reported to be under optioi
 to Chas. Flynn. representing Bisbee ties. These groups cover a large are
 of the diorite cross dikes and irol
 ledges and are very promising To tn
 north of the Cobralla is the Calico kis
 group, where small amount of vorl
 is being done upon the iron ledges.
 As the Yuma. Cobralla. Ultimatul
 and Carbonate Hill properties are &
 closely related in character and ar' the four main Lime Belt properties a short description of the general Seo l logical features will be of interes' The core of the main Harcuvar rang is granite, superimposed upon tn northerly and westerly slope of whic are the sedimentary schists and linn,
 stones. forming the low foothills; th general strike of the schists ant limestones. paralleling the main rang
 and the dip to the north varying frol : about thirty degrees to sixty-five d. | grees in places. Immense graniti Il porpbyry or monzonite masses hay a been intruded into and between tn | schists and limestones, generally 2 sills following the bedding planes an
 qualification: less frequently as eros :. aikes following fracture planes
 Il At a later period there has been il
 truded a very regular series of diori' l cross dikes, cutting everything, grai
 ite, monzonite, schists and limsstone ! These dikes occur for ten or tweiV miles in the Harcuvars, from Salon
 Peak westward to the Yuma propert = and are undoubtedly one of the maj | causes of the naturalization. In tn granite and schists they are often
 companied by contact ledges, ITO |. capped on the surface and changil
 to copper sulphides carrying gold all
 silver values with depth; in some ! q stances the entire dike matter ha s- been replaced and shows the chara z teristic iron gossan for several tho a i, sand feet in length and twenty
 thirty feet in width.
 Q The copper ores invariably carr D gold and silver values throughout u
 district, averaging from l. to S2 y gold and silver for each per cent copper. making it possible to conce
 trate low grade ores to economics
