and superintendence, the following may express the proper capital and 
working expenses for extracting the gold from the two classes of ore 
occurring in New Hampshire: 
Quartz mining. Sulphurets.

Should a company be formed to extract gold from the quartz or sulphu- 
rets, these figures express the capital absolutely necessary for the under- 
taking and the proper running expenses. Circumstances of various kinds 
might add to or diminish the amount of necessary capital; but there 
would not be much variation from the figures given for the running ex- 
penses. 
It is easy, from these figures, to estimate the income which might be 
obtained from a single enterprise of this nature. If the ore averaged as 
high as $19 per ton, as stated by Dr. Rae, the profit on each ton milled 
should be $14.90. Eight tons were carried through the whole process 
daily in 1875. That should afford a daily profit of $119.20. Supposing 
that the daily yield be practically $15, which was the case in the earlier 
workings, and allowing $10 per ton for the net income, we should have 
$80 as the daily return to the company, or $20,000 for the year of 250 
working days. These figures are indications of what the gold mining 
business might become in our state when properly and economically con- 
ducted. A larger capital, mills of greater capacity, and the reduction of 
a greater number of tons daily, by employing night labor, would add 
very much to the amount realized. I have not given the results obtained 
from working the sulphurets. Those given from essentially actual ex- 
perience are to be preferred ; and they will afford a method of estimating 
the possible merits of the gold mining and milling business.
