MIEING INDFSTflY, 



more than 100 feet cuts a ledge supposed to be the Warren. The explora- 

 tion of this was in progress in September, 1869, but no very definite results 

 had then been obtained. 



The costs of mining and milling operations appear to be no less in the 

 Lane and Fuller than in the Manhattan mine. The company published a 

 report for the year ending June 30, 1869, from which the statement of 

 expenditures given below is drawn. The account is not sufficiently analytical 

 in its character to show the relation existing between the cost of prospecting 

 and improvements on one hand, and the actual mining and milling expense on 

 the other. During the year, however, the shaft was sunk from a depth of 

 about 300 feet to a depth of 445 feet ; 3,282 feet of drifts were run. An addi- 

 tional engine of 30 horse-power was placed at the shaft-house and the pump 

 was provided and set in the mine. A fire-engine and steam saw were also 

 purchased. The product during the time was l,0292%%^o tons of ore, which 

 yielded $224,050 38, averaging $217 68 per ton. It will be seen that the 

 total expenditure for current operations, prospecting and improvements taken 

 altogether, amount to over $200 per ton of ore produced.
