Vein, if it holds ics present inclination, must cut the older lodes at the 

 depth of four or five hundred feet, and its situation is such that ample drain 

 age and ventilation can be obtained. 



GOLD TUNNEL MINE. 



The mine bearing this namfe is located half a mile west of the town of 

 Nevada, on Deer Creek, and has been worked successfully since its discov 

 ery in 1850 or '51. It was originally a placer claim and was found while 

 working the banks of the creek for placer gold. Soon after its discovery 

 an engine was erected upon the ground and the vein opened ; it was com 

 menced by driving an adit level on the vein, which was subsequently aban 

 doned and a new level commenced at the point at which the present reduc 

 tion works are situated. 



The length of the present level is three hundred arid seventy-five feet, 

 and has an inclination of ten degrees from the horizontal line ; three winzes 

 have been drove on the lower side of the adit [L. F. II.] which are respec 

 tively thirty, twenty and twelve feet, with a level of twenty-five feet be 

 tween the winzes F. and H. On the opposite side two cements of fifty feet 

 each, and a gallery connecting both, of one hundred and twenty-five feet, 

 w r ith a corresponding one connecting the winzes on the lower side. All the 

 ore included within the dash lines has been stopped out. 'flfa^ vein is situ 

 ated in granite, and thus far has been loose and incoherent ; tfcis is attribut 

 able to the large amount of pyrites contained in the vein, as is sh< wn at any 

 point ^here the quartz retains any solidity ; the gold is in a free state in the 

 gossan, of which there are large quantities throughout the mine ; the operators 

 on this vein have been eminently successful, and their mine bids fair to con 

 tinue valuable. The strike of their vein, north ten degrees east, dipping 

 east ten degrees south, at an angle of thirty-eight degrees. 



ILLINOIS MINE. 



The Illinois Mine is situated directly opposite the Gold Tunnel on the 

 south bank of Deer Creek, and is a continuation of the same vein , it has 

 all the characteristics of the former throughout. The length of their upper 

 gallery is four hundred and fifty feet and that of the lower, two hundred and 

 fifty ; two cross-cuts have been driven which connect the galleries at C. D. 

 each fifty feet in length. 



JONES AND DAVIS MINE, HERBERTVILLE, CALAVERAS 



COUNTY. 



The mine of this company is located on the east side of a small tributary 

 running into Amidor Creek, the latter passes through the town of Amidor 

 one mile north of this mine ; the top of the whim-shaft, C, is one hundred 

 and forty-five feet above the level of the creek, and ninety feet below the 

 outcrop of the ve^a on which the shaft, C, has been sunk ; at shaft 4 the
