Bad Boys of Cripple Creek Mining Company, Inc. proposes to open a shallow open
pit mine with limited production, for the purpose of mining high quality Turquoise
gem material from its properties on Mineral Hill just north of Cripple Creek,
Colorado.
The Cripple Creek and Victor Gold Mining District produced over 20 million ounces
of gold and two million ounces of silver since its discovery in 1891. Nearly all of the
mining activity took place south of Cripple Creek. However minor gold occurrences
of a similar type were found on Mineral Hill and it is considered part of the District.
A large number of prospects pits and shafts are located on Mineral Hill and were
probably the reason that the turquoise deposits were found during modern times,
Turquoise production was reported from the District as early as 1894.
Mineral Hill is unique in the District for its deposits of free gold and turquoise.
Literature on turquoise clearly recognizes that the Cripple Creek area is an
important producer of gem quality material.
The total area impacted by mining on this permit will be less than one acre, much of
the area is required to store mined material until it can be backfilled. There may be
some gold production that would be incidental, however no processing will take
place at the site. Production rates are anticipated to be on the order of an average of
one ton per day.
TURQUOISE
Turquoise is a gemstone that has been valued by mankind since antiquity.
Chemically it is a hydrous basic aluminum phosphate plus copper and ferric iron.
Cu(A1,Fe)6(P04)4(OH)8 4H2O
Prized stones are fairly hard, with a hardness of just under six on the Moh's scale, a
mineralogical standard, which means that it will scratch glass and in turn will be
scratched by quartz. Less quality material can be much softer.
Color is generally the "essence" of turquoise which ranges from a sky blue to green.
The matrix of turquoise is vein matter of the enclosing rocks that is intermingled
and generally cannot be separated. It can be stained by iron oxides into different
colors and can include quartz. Matrix material often can establish the fact that the
stones are genuine or natural. The production from the Bad Boys pit may include
some go]d in the matrix.
The turquoise mined historically from the permit area and adjacent areas, is hard,
and of good color and has a "high dollar density."
