Marble - Colorado Geological Survey

from Idaho, Tennessee, Vermont, and
Europe and would be very interested in the
Conundum Creek occurrence. Gene says the
quality would be better at depth but coring
would only tell engineering properties and
not how well it takes a shine. They will do
all of the testing and evaluation for free and
conduct the marketing. Stone must have no
brown, or soft spots in it. He says slab costs
are $175.

Mathews, April 6,1989
A market consultant especially for international
markets, conducted a market study
for a Chinese Black Marble (very black).
Black marbles are in demand but must run
tests and have samples to determine the
market. He says tests are most important,
modules of rupture, density, tensile strength,
flexural strength, abrasion, running approximately
$800 for the testing. Must know
mine production capability also to tell user.
Must have contacts on a world-wide basis for
marketing the material.

I told her about the dark gray marble, she
said black granite real hot, no one can keep
supplies in stock. Said Mexican black marble
sells for $14 per tile, $7-8 to contractors,
sells 30,000 sq ft/yr of black. Dark gray
would have much more competition but
could still sell 10,000 to 20,000square foot
per year but would be a much harder market
to break into. Quarries have 100's of
distributors. 3 ft by 3 ft by 3 ft would be ok
for tiles but no good for the slabs she sells.
She buys from European fabricators because
U.S. black marble not available and labor
costs too high.
The cheapest is travertine as natural rock
say $4 per tile but agglomerate $3 per tile.
Aggregate is not poured but the mixture of
pieces cemented together, cut and polished.

They do not toll saw other quarry's blocks
but are thinking about another product line
to complement their quartzite. Black marble
now is in extremely high demand and Don
would be delighted to send their quarry
expert Dr. Hollenbaugh, Boise State College,
to Conundrum Creek to examine the deposit
at no charge. He wanted a softball sized
piece to examine. He stated that cannot use
wire saws in winter months.
Idaho Travertine, (208) 529-4207, Ted Orchard,
October 27,1989
Idaho travertine custom saws tile for $2.65
per asquare foot and is now working on
some Tennessee marble which costs $2500
per block to ship. Approximately 14 tiles can
be obtained from a cubic foot. They deal in
planks which are 4.5 in. by 13 in. by 3-5 ft to
minimize waste. They can handle up to
10,000 tiles/month with their two large
diamond gang saws. One 9 ft dia radial saw,
three monolama single blade saws, and
splitting saws with two sets of five blades in
tile splitting saws. Will do custom slabs for
$5.00 per swuare foot 7/8 in. thick or larger.
This is $192/slab.
Colorado Yule Marble Company, Denver,
Colorado, Rex Luesby, October 24,1989
Supplied me with tax information and
generalized other costs, plans, and
suggested that there might be an
opportunity to toll fabricate or buy whole,
sound, blocks for $10-12 per cubic foot.

Nelson, October 27,1989
Just purchased Tennesee Pink, employs
Claude Ledgewood. Is travelling to Italy to
buy equipment for a tile line did not commit
to wanting feed stock.
U.S. Bureau of Mines, Washington, D.C., (202)
634-1185, Val Teportei, October 27,1989
Called to get price quotes on limestone and
any uses for the waste stream from a black
marble quarry. He said that tonnage was too
low and distance to market too far to justify
any use for the waste material.
