.LOTAWANA PLACER MINING ENTERPRISE
BIG SLUlCING PROJECT ON SAN
 DOMINGO WASH.
Old Time Gold Field to Be Worked By Tried and Approved
 Methods.

Extending from near the river back to the hills to the east of the Hassa- yampa. between Wickenburg and Hot Springs Junction are the Lotawana Mining company's placer claims.
 This company controls 1000 acres or land, located with view to cover ing number of washes on either side of san Domingo canyon. The flat country between the hills and river is in general underlaid by bed of cement ed gravel or conSlomcrate. During the process of carving out the diff ferent washes by intermttant torrcn- tial flooding these graVels have been concentrated and with additions from the hill slopes the resulting placers have been formed.
 Thedistrict is well known as dry placer digginGs. and formerly there was good sized Mexican town on san Domingo populated by dry wash CTS. The Lotawana holdings were taken over three wears ago by John Sanger. an Aslaskan placer miner who formed the Lotawana Mining company that is now engaged in de- veloping the properties.
 There are a number of washes in which the gold bearing gravel occurs and several have been test pittrd and their values pretty well demonstrated The first production will come from the Rodgers wash. which has been unusually well tested. several hum dred pits having been sunk on an area 2l2 miles long and 1000 feet average width, showing an average depth of nine feet and value of better than 4u cents per cubic yard The pay dirt here runs from the sur face to bedrock and is a sandy gravel with angular boulderS. none of size sufficient to hamper operations. is free from clay and can he handled at minimum cost provided the water supply is sufficient
 The water can be economically de- veloped by putting a dam in an eN- tremely narrow canyon tributary to san Domingo In this favorable place concrete structure can be erected. six feet long at the bottom and l26 at the crest with a height of 60 feet and d basal thickness of 2S feet This will impound approximately 100000, 0O0 gallons. with sufficient head to command Rodgers wash and the other eulches below.
 The ultimate intention of the opera tors iS to use the water supply in connection with the Lidgerwood drag line eXcaVatOr and mechanical washer with sluice boxes the water to be reused and the dam supply replacing that lost by Seepage and evaporation IL is contemplated that the eNcaVator and washing machinery will be oper- atcd by electricity generated in plant on the railroad operated by Diesel crude oil engines.
 At present work k going on to pre- pare a grade for d small pipe line that will lead from a pumping plant in san Domingo to the head of Rodg- CTS wash to utilize the present water supply AS soon as this line is in work will be started with Sluice boxes. using blows and scrapers To eNcaVate the dirt As the best dirt will be washed the work will prob able show a fair margin of profit, though not nearly so remunerative per yard as the work with the Lidg erwoOd machine.
 The larger plant contemplated later will wash 2O00 yards of dirt and the working cost is estimated at around 10 cents per yard. With 40 cent dirt. which is a conservative estimate, and the large area of glod bearing terri tory which this company controls long and prosperous career can he predicted for it.
 The property was recently examined and reported upon favorably by T. Lane Carter. a well known South Af- rican engineer and an operator in the Rand district. He has also oper- ated placers in Nicaragua. \ couple Of local engineers have also examined it.
