HERBERTVILLE MINE, SUTTER, AMADOR COUNTY. 



This mine has been alluded to in former reports, and is among the earliest that 

 were opened in this State. Its operations have continued almost uninterrupted 

 until during the past year. During this year but a small amount of ore has been 

 reduced, in consequence of the failure of water to supply the motive power, the 

 company having removed their engine on the erection of their large water-wheel 

 in the latter part of 1854. 



This has proved a serious inconvenience, not only to this company but also the 

 Midian, adjoining, both of which were dependent on the water of an adjoining 

 canal to continue operations in reduction. 



After the failure of the water the Director of the mine continued the sinking 

 of the two whim-shafts, and the driving of the levels between them. Little, there 

 fore, has been done other than to open the mine to a greater extent than formerlj 

 existed. This has been done at a heavy expense, and the small amount of ore re 

 duced has nearly met the liabilities incurred. 



The condition of the mine at the close of 1854 was as follows: 



The south shaft had been sunk to the depth of twenty-three and a half fathoms 

 and the north shaft to sixteen fathoms, with levels, uniting the shafts which are 

 distant from each other, one hundred and twenty feet, and extending beyond the 

 shafts the length of two hundred and eighty feet, inclusive. 



The work this past year consists in the sinking of the south shaft to the depth 

 of thirty-six fathoms and the north shaft to thirty fathoms. From the bottom of 

 the thirty-six-fathom shaft, levels have been driven each way and between shafts 

 to the length of three hundred and twenty feet, the middle gallery to the length 

 of one hundred and eighty feet, and the upper gallery two hundred and thirty 

 feet; distance between levels sixty feet. 



At this depth the ore maintains the same features as formerly, being highly py- 

 ritous.
