during the period of operation would justify additional exploratory 
work on this property. 
The Smith mine. The shaft of the Smith mine, which is the 
most northerly of the workings on the westerly belt of ore, is ap- 
proximately 800 feet west of the line along which the Long open- 
ings lie, and about 800 or 1000 feet west of the general easterly 
belt of ore in which the Augusta-Cook-Scott mines were opened. 
A large swamp obscures structural relations ordinarily observable 
at the surface, but the Mountain and Smith mines le in the same 
general line of strike, and there is a zone of strong magnetic attrac- 
tion along this direction which indicates a continuance of the ore 
body between the two mines. There are no data available with 
respect to this old mine. Nothing can be seen on the ground but an 
old opening, or shaft, about 30 feet in depth; it was stated that a 
body of magnetite about 2 feet thick was encountered at the bottom 
of this shaft. 
The Mountain mine. Ore was discovered here in 1758 “by a 
hunter, in consequence of a tree being blown up by the roots” +>, An 
extension of the ore was discovered in 1831 and a mine, called the 
Patterson, was opened, from which 7000 tons of ore were taken 
between 1831 and 1839. 
The Patterson and the Mountain mines may be regarded as a 
single unit; the workings running together in a series of cuts and 
pits extending over 1000 feet along the surface. The strike of the 
ore body is north 20° east, the dip 83° southeast and the pitch is 
to the northeast at an indeterminable angle. The mine was worked 
by a series of open cuts along the strike of the ore, which was 
followed down the dip and under the hanging wall for a depth 
unknown, possibly determined by the capacity of the pumps used to 
remove the water which subsequently drowned the underground 
workings. Nothing can be seen at the present time but an open cut, 
caved more or less, overgrown with brush, containing water in some 
places and half full of fallen rock elsewhere. 
At the north end of the property a vertical shaft was sunk. The 
Ramapo Ore Company dewatered this shaft during the course of 
their preliminary exploratory work, and found it to be about I00 
feet in depth; a body of good ore 7 feet in thickness was encountered 
at the bottom of the shaft. 
Both the Mountain mine and the Smith mine workings are offset
