were hoisted from this mine. Operations were then suspended. A 
continuation of this ore body was operated under the name of the 
Antone mine, from which 50,000 tons of ore were removed, the ore 
body having a thickness of from 5 to 8 feet. 
The old workings lie nearly opposite to and not more than 800 
feet west of the Cook and Scott mines, on the westerly belt. The 
major fault crosses the ore line in a diagonal direction and offsets 
it from the Mountain and Smith mines (see fig. 9). The strike 
of the open cut is approximately north 20° east, and the dip of the 
ore is apparently about 85° southeast. The cuts were sunk through 
a drift cover; they are more or less filled with débris, in places with 
water, and all are brush-grown. 
In nearly all these old workings a little ore still may be seen on the 
walls, in many cases this being the only source of the specimens 
collected. From what evidence is presented by these traces of ore 
left, it is judged that the ore here is massive, rather coarsely 
crystalline, blocky and strongly jointed, breaking out in straight 
sided blocks, and retaining many remnants of still unreplaced rock. 
The magnetite, as seen in the walls, cuts the structure of the wall 
rock (Pochuck-Grenville) in stringers, and fades away in wedgelike 
streaks. Associated with the ore is a coarse pegmatite, which badly . 
cuts up the ore in places and probably exists in dikelike form else- 
where. 
It should be remarked that this pegmatite, which cuts the ore in 
all these workings, may very possibly disappear in depth in the same 
way that the large pegmatite dike which cuts the Scott ore body 
wedges out downward and vanishes on the 400-foot level. 
It will thus be seen that in this restricted area twenty-two mines 
and prospect pits are situated on several subsidiary belts of mag- 
netite. All these have been operated in the past, and all of them 
are now leased and some of them operated by the Ramapo Ore 
Company. This company has dewatered three of the mines, the 
Lake, Scott and Cook, and installed a magnetic concentrator, 
electric hoists, dryers and other improvements preparatory to active 
production. The remaining mines have not produced ore in many 
years, some having closed down half a century ago, and at least one 
has not been in operation for over a hundred years. Not one of 
them has been bottomed ; considering the general geological relations, 
the reputed thickness of some of the ore bodies and the behavior of 
the ore in those mines inspected underground, it seems reasonable to 
conclude that taken altogether these properties constitute an ore 
reserve of considerable magnitude and value.
