The Sleeping Beauty turquoise mine is located seven miles from Globe,
Arizona. The mine is one of the largest producers of turquoise in
North America. The mine, and the turquoise extracted from it, derives
its name from Sleeping Beauty Mountain, which at one time was part of
the Copper Cities operation. The center of the copper mine is located
at approximately 33o24"13.23"N. 110o53'34.60"W, at an elevation of 1224
feet. Sleeping Beauty Turquoise Mining is presently owned and operated
by Monty Nichols.
For
many centuries before the first Europeans made their way into Arizona,
turquoise was being mined on the slopes of Sleeping Beauty Mountain.
The Salado and other ancient peoples mined the beautiful sky stone from
several surface outcroppings located in the vicinity, including Pinto
Valley. It is believed that Spanish explorers were the first Europeans
to locate the source of Sleeping Beauty sometime around the 1860s. By
the 1870s, small underground mines pock-marked the hills surrounding
present day Globe.
Cities Service Company started the Copper
Cities Mine (commonly called the Sleeping Beauty Mine) in 1952 and
operated it until the Pinto Valley mine opened in 1972. During the
1960s, L.W. Hardy had the contract to mine turquoise, both at Sleeping
Beauty and at Castle Dome, later called the Pinto Valley Mine.
Formerly a meat cutter at a market in Miami, Hardy recognized early on
that turquoise was more valuable as a gem stone than the associated
copper.
By the time the turquoise boom began, Hardy had
contracts with mining companies in Miami, Kingman and elsewhere. He
also developed a method for stabilizing low-grade, porous turquoise
with pressure-impregnated hot acrylic resin, which hardened the stone
and improved the color.
Hardy's mining methods were primitive
when compared with current operations. Hardy's workers sat in a ditch
ripped by a bulldozer and hand picked the stone from waste-rock. Hardy
mined turquoise at Sleeping Beauty for 22 years, getting about 45
percent recovery, and leaving the rest in waste dumps.
Monty
Nichols received the contract to mine Sleeping Beauty turquoise in
1988, and began using modern mining methods to develop the property.
Nichols drills and blasts the overburden, hauling it to the abandoned
Copper Cities pit which now contains the recycled tailings from Miami
Copper Company's No. 5 tailing dam. The old dam dominated the eastern
skyline of downtown Miami until recently. The year Nichols acquired
the contract, he began a two-year project to remove 5,000.000 tons of
overburden. Located half way up the side of an open pit mine, the
narrow turquoise-bearing zone has about 400 feet of hard waste rock on
top of it. In order to move sideways into the ore-body, a whole slice
of the mountain had to be removed.
To avoid fracturing the
turquoise, Nichols was careful not to blast too near the
turquoise-bearing strata. That layer is more crumbly, so the miners
can rip it and dump it over screens, separating the material by size.
No crushers are used, again to avoid fracturing the gemstone, and the
different sized rock is hauled up to a wide mine bench where conveyor
belts move the material through three buildings. There, workers hand
pick turquoise from the broken rock. The buildings are vented with
filtered air to eliminate workers' exposure to dust, and well insulated
to keep them comfortable in any weather. It is a far cry from the old
methods of mining. Anywhere from 30 to 40 people work at the mine at
any one time, depending on how much mining there is to do.
Fifty
years ago, mine workers filled lunch buckets with the colorful rock,
even though it was reason for immediate termination. Old habits die
hard, and some people still think it is okay to sneak in and try to
pick turquoise. As a result, security is tight in and around the
mine. Motion detectors, night vision cameras and 24/7 roving patrols
are used, so the only turquoise leaving the property now is being
shipped to markets around the world.
Italy is the largest volume
buyer of Sleeping Beauty turquoise, with Germany and Hong Kong
following closely behind. These customers buy the best grade for their
exclusive jewelry. Jewelry makers in India and Spain also receive
Sleeping Beauty turquoise, while in the U.S., Gallup and Albuquerque
are the largest consumers.
The Sleeping Beauty turquoise mine
produces a uniform light to medium blue turquoise with rare finds of
deep, dark blue. Because of its uniformity, it has been a favorite of
the Zuni Pueblo. Zuni silversmiths often use it in channel inlay and
various types of cluster work that require large numbers of small,
perfectly matched stones The Sleeping Beauty mine has been one of the
larger producers of rough turquoise in the United States, although
today much less good turquoise is being produced than in the past.
Sleeping
Beauty turquoise is noted for its solid, light blue color with no
matrix; the host rock is usually granite. Nichols says the mine is
producing about 1,600 pounds a month. Of that, only four percent is
natural; most of the turquoise from the mine is altered in some way.
Most is enhanced, which is more expensive than stabilization, and sold
to large distributors in this country and Europe. Currently most of the
turquoise that comes from the mine is from the tons of tailings piles
that have been accumulating for decades.
The best of the
Sleeping Beauty turquoise is comparable to that found in the Middle
East. It is thought that large quantities of Sleeping Beauty turquoise
is taken overseas and smuggled into, then out of, Iran to be sold as
“Persian” turquoise.
