Show MINING IN california SPECIAL correspondence san sail francisco california dec 27 the year 1911 has been an unusually good one in california so far as mining is concerned due to the capital that has been invested from outside sources such as colorado revada nevada arizona and many other states as well as the english and french syndicates the dredge operations in the vicinity of orville are looking better than for many years due to the fact that deeper ground can now be worked as the large boats handle the dirt at a very small cost and it has been predicted that the old ground will be reworked at a profit in fact all dredge operations throughout this state have been highly successful A number of old drift mines have been mended that prospecting be started as soon as possible plumas county is having a revival also and nevada mining men in particular are looking for claims in this county the oversight quartz mine in southern plumas has struck some rith rich ore although but little development work has been done the ore seems to be in the form of arsenical sulphur ets with some free gold present and this shipping ore is being sacked for the smelter mining men familiar with the famous alleghany allegheny Alleg hany district state that this property should make a big mine as depth should expose excellent ore bodies pose excellent ore bodies the formation being a serpentine porphyry contact is mm I 1 ault V ji M MIN biffi omit 9 0 4 IWO 1 1 na 1 ap VI 6 0 gold dredge mining in california reopened and excellent results are being obtained some of the old placers near columbia tuolumne county are receiving attention and work is being done to decide the best method of handling the dirt the same conditions exist in placer and in sierra counties A double com compartment param ent shaft is being sunk on the columbia basin placer ground to cut the bedrock bed rock and rich ground has been exposed thus far the company expects to sink to a depth of feet the mammoth placer is also being opened up to tap the rich gravel this property is in placer county the mines of madera county are attracting attention and a number of men are at work on several of the old claims capitalists ita lists have sent experts to grub gulch and the reports on holdings in this section are said to be first class and have becom similar to alleghany allegheny Alleg hany and the porphyry dyke having considerable width is a splendid indication of ore chutes the pearl quartz claims are to be developed also so that this district will materially teri ally aid in the mineral output of plumas county the mines in the greenville district are also looking up and some of the old properties are being developed in the mohawk section the judge hayden bullion mine is being prospected and a ledge of 40 rock has been exposed at a depth of feet and at a distance of feet from the portal of the tunnel the shaft on the brown bear gravel mine on st charles hill sierra county has reached bedrock bed rock and it prospects enough to warrant development work the nugget nell placer ground at downieville Downie ville has been bonded to J C of san francisco and the old channel will be proven up the quartz mines on the mother lode are producing steadily and good dividends are being paid the mother lode of california extends from the southern part of mariposa county in a northwesterly direction to the northern portion of el dorado county the distance covered is some twelve miles the droppings crop pings are usually strong and well denfield den fied and the gold values increase as depth is obtained in some instances barren zones have been encountered from the to the 1100 foot levels and then again this zone has been in evidence from the 1000 to the 1400 among the famous of the mother lode may be mentioned the kennedy the deepest mine in this state having a foot shaft and a stamp mill this famous property has been worked for nearly fifty years the keystone another noted mine has a production of some all taken from a depth of feet the eureka consolidated with a production of was discovered sixty years ago an and the e best es va values aes ues were found oun below the foot level the argonaut adjoining the kennedy lis is also a famous producer of the yellow metal among others are the plymouth consolidated soli dated where rich ore was discovered on the surface the grover with a production of over the central eureka near the eureka consolidated where a shaft was sunk nearly 1000 feet before the ore body was struck the south eureka to the south of the central eureka which mine had no droppings crop pings the oneida with a 2000 foot shaft the given in calaveras talaveras Cala veras county the jumper in tuolumne county with a production of the rawhide with a yield of some the princeton in mar mariposa inosa cou county nty yielding some and the dutch and opp both good producers there can be no doubt but that many of the old abandoned mines can be reopened and made to yield handsome returns and the mining investor is beginning to realize that fact as is shown in the case of the plumas eureka in plumas county california is certainly a prot flable field for the miner as well as for the capitalist and with plenty of wood and water at hand the operating expense is much less than in nevada and the climatic superior in in every respect
