Palmer shaft is an inclined shaft, sunk in the footwall gneiss,
through which all hoisting of ore from the mine has been done since
Parker shaft was a vertical shaft, sunk through the limestone,
from which a crosscut was run at a depth of about 1,000 feet to intersect
the ore body. Somewhere, probably near the ore, this crosscut encountered
abundant pegmatite and a pneumatolytic deposit of extraordinary complexity,
whose form, however, is unknown and whose nature is known only from
specimens collected on the dump. The minerals found include native
lead and copper, clinohedrite, roeblingite, hancockite, glaucochroite,
franklinite, leucophoenicite, cyprine, nasonite, axinite, datolite,
willemite in exceptional crystals, barite, rhodonite, garnet, phlogopite,
and many others. The Parker shaft was for a long time one of the chief
openings of the mine, and minerals brought out through it may have
come from almost anywhere in a considerable underground area.
Hamburg mine was a small open pit on the outcrop, in which were
found transverse veins containing sussexite, pyrochroite, greenockite,
rhodochrosite, and remarkable radiate masses of fibrous willemite.
Trotter mine was an inclined shaft in which the ore body was cut
by numerous dikes of pegmatite containing fine microcline, thorite,
zircon, titanite, and allanite. Notable contact effects were revealed,
with the development of much garnet, pyroxene, rhodonite, and biotite
and its alteration to caswellite and axinite. At the depth of 340
feet the shaft penetrated a pneumatolytic deposit consisting of yellow
sphalerite, purple fluorite, niccolite, and chloanthite, the niccolite
being partly altered to desaulesite. Secondary veins of sphalerite
and recrystallizations of the primary minerals are common in specimens
that were found on the dump from the Trotter shaft.
was the outcrop, no longer in existence, of a large mass of pegmatite
near the Trotter shaft, where abundant large crystals of garnet and
pyroxene were found in the adjacent limestone.
the west wall of the Buckwheat open cut was exposed a veinlike
mass of gray dolomite containing in its cavities crystals of quartz,
dolomite, albite, sphalerite, pyrite, millerite, and goethite.
tunnel to the Wallkill River from the Buckwheat open cut yielded
the unique cubical crystals of gahnite described by Brush (100).
Buckwheat mine (Buckwheat open cut or Southwest opening) the ore
body was exposed by stripping of the overlying limestone in the pitching
trough. Both the ore and the stripping yielded many interesting minerals
contained chiefly in transverse secondary veins of great variety.

The Taylor mine, the deeper workings of this area, yielded similar
Franklin Iron Companys quarry is in white limestone cut
by pegmatite veins. Abundant metamorphic minerals, notably graphite,
pyrite, pyrrhotite, arsenopyrite, fluorite, edenite, titanite, norbergite,
tourmaline, and spinel, have been found there.
locality. In excavating in limestone for the foundation of the
old iron furnace, pockets were found containing corundum, spinel,
rutile, marcasite, mica, hornblende, and other minerals, according
to Mr. Hancock.
Furnace quarry is an abandoned quarry in white limestone, which
formerly yielded numerous metamorphic minerals similar to those found
at locality 9.
Hill is the site of numerous magnetite mines, including the Hill
mine and the Gooseberry mine, where were found scapolite, zircon,
pyroxene, black garnet, and many other minerals.
Fowler quarry, in white limestone, was once noted for crystals
of pyrite and green tourmaline isolated in limestone. More recently
pyrrhotite, brown tourmaline, graphite, edenite, spinel, and phlogopite
have been the chief minerals found.
this locality were found loose boulders of limestone containing,
according to Mr. Canfield, large crystals of phlogopite.
this locality, on the east leg of the ore body at Sterling Hill,
was found the pocket containing the largest crystals of franklinite
and of troostite in the Canfield collection. The principal locality
for roepperite was nearby.
calamine pit of the Passaic mine yielded most of the finer specimens
of calamine and of large red garnets and the minerals chalcophanite
Lord Stirling pits were those from which zincite was mined by
Lord Stirling about 1772.
calamine pit of the Noble mine, in which the calamine was mostly
iron-stained, yielded corundum and the only tourmaline found in the
dysluite locality was an opening in the wall of the east leg of
the ore body at Sterling Hill, where were found the remarkable large
gahnites with garnet and jeffersonite, preserved in the Canfield collection.
the mouth of a tunnel into the Noble mine was found a large pocket
in limestone, containing large and complex crystals of aluminous pyroxene
