The Pockets (to date)
Discovery Pocket
As the name implies, the Discovery pocket was the
first major pocket encounter in the mine. The pocket was breached during
mining operations and an untold number of specimens were sent to the mill.
The pocket lies in the back (ceiling) of the 200 level in the main
shaft. Vanadinite from the Discovery pocket frequently forms attractive
specimens generously sprinkled with dark brown lustrous barrel shaped crystals.
Labor Day Pocket
Shortly before the 2003 Denver show the Labor Day
pocket was encountered deep in the main shaft. The pocket is a watercourse
in massive barite. This pocket was breached during mining operations and
an untold number of specimens were sent to the mill. Vanadinite from the
Labor Day pocket is generally a dark red color and forms long acicular crystals, often
capped by a later generation of calcite. Much material remains to be
collected from the Labor Day pocket.

Looking into the Labor Day pocket.
The entire length of the pocket is lined with long dark red acicular vanadinite
crystals, often the vanadinite crystals are capped by a later generation of
calcite.
Candle Box Raise Pocket
The Candle Box Raise pocket was encountered in a
small raise from the 200 level. An uncommon W & H Walker's candle
box was found near the raise, hence the name. The Candle Box Raise pocket
was a small cavity that was breached when the raise was driven. The pocket
actually had a mine timber jammed into it. Vanadinite from the pocket
formed lustrous dark crystals with bright red tips. Although only a few
specimens were recovered, they are among the finest from the mine. In the
rock surrounding the pocket, a number of small vugs were found that contained
attractive microcrystals of transparent yellow wulfenite.
Silver Medal Pocket
The Silver Medal pocket is a narrow mineralized
cavity between unaltered limestone and massive barite. The pocket was
breached by early mining methods and an unknown number of specimens were sent to
the mill. Named for a number of Silver Medal blasting cap tins that were
found nearby: the Silver Medal pocket has produced some attractive specimens.
The vanadinite tends to be more "normal" and forms simple red hexagonal prisms
averaging about 1cm in length.

today. The rock on the right is unaltered limestone and on the left is
altered limestone and massive barite.
Double Owl Pocket
In inactive mines it is not uncommon to find
objects left by either the original miners, or visitors over the years.
Over the years I have encountered a number of such objects. In the North
Home mine the remains of a 1929 Mills "Torch Front" slot machine have been
found; the slot machine has two owls embossed on the front, hence the pocket
name. Vanadinite from the Double Owl commonly occurs as tapered rice
shaped crystals in shades of red, yellow, and sliver-green. Occasionally
there are bright red microcrystals of vanadinite forming a druse between
the larger crystals.

"Torch Front" slot machine.
Thanksgiving Pocket
The Thanksgiving pocket was encountered on
Thanksgiving in 2003. It was the first intact pocket encountered in the
mine. Over the holiday weekend 789 specimens were extracted from the
pocket's depths; during the next few months several hundred additional specimens
were recovered. The specimens from the pocket generally form delicate
branching crystal groups in shades of red, yellow, green, orange, and reddish
brown. Accessory minerals from the pocket are limited to sparse calcite
and two specimens of barite.

Here is a view looking into the
Thanksgiving pocket.
Thanksgiving Pocket Extension
During the fall of 2007, an extension to the
Thanksgiving pocket was encountered. Specimens from the extension
generally resemble those from the Thanksgiving pocket, but have a more
noticeable reddish-brown color, curved in habit, and are often topped with
white calcite.
Halloween Pocket
The Halloween pocket was encountered on Halloween,
2007. Vanadinite from the pocket usually occurs as prismatic crystals that
are often a dark, nearly black color with lighter colored terminations. A
few specimens are associated with minor amounts of white calcite.
Hidden Pocket
Found tucked behind a mine timber was a small
pocket now known as the Hidden pocket. Specimens from the Hidden pocket
resemble those from the Double Owl pocket.
Little Muddy Pocket
In early 2005 a small mud filled cavity was
encountered near the Discovery pocket. Much fine grained mud was present
in the pocket and indicates a lengthy continuation of the pocket. The
pocket is the only one encountered thus far that contained any mud or clay.
Vanadinite from the Little Muddy pocket resembles that of the Discovery pocket
although it tends to be a lighter color and forms attractive specimens studded
with light brown barrel shaped crystals.
Bad Place Pocket
In a rather nasty place about sixty feet from the
collar of the No. 2 shaft, the Bad Place pocket was encountered. The
pocket produced several specimens of descloizite epimorphs after vanadinite.
Rarely vanadinite was found with a druse of parasitic descloizite microcrystals.
Midway Pocket
In the back (ceiling) of the 100 level crosscut
between the main and No. 2 shafts the Midway pocket was found. Colorless
to white calcite was found lining the pocket. The calcite frequently
formed stalactite like formations. A single specimen was found with a
cluster of colorless transparent aragonite crystals perched upon the calcite.
January Pocket
In early 2005 the January pocket was encountered in
the No. 2 shaft below the 100 level crosscut. The interior of the pocket
was lined with a number of orange to yellow pseudo cubic wulfenite crystals
reaching 1cm in size. Yellow to orange-red botryoidal vanadinite was also
found in the pocket. Outside of the main pocket a number of small vugs
were encountered that contained colorless transparent willemite microcrystals
along with blocky yellow-green chlorargyrite crystals. Rarely scattered
microcrystals of cerussite, calcite, rosasite, aurichalcite and hemimorphite
were found.

The January pocket is located above and to
the right of the ladder.
Starvation Pocket
A narrow breccia zone was encountered between two
stopes off of the 200 level. Within this breccia zone a small cavity was
found that contained a number of attractive specimens. The specimens from
the Starvation pocket commonly have dark red, nearly black, vanadinite crystals
reaching more than 1cm in size. Often the vanadinite crystals have a
yellow-tan outer layer.
Chipmunk Pocket
The Chipmunk pocket was breached in the fall of
2008 and is in the same general area as the Thanksgiving pocket. Specimens
from the Chipmunk pocket are often associated with calcite and commonly have
hopper shaped vanadinite crystals that range from red-brown through green-brown.
